300E Turbo LPG Project

I have hit the seller up for half the repair bill so am now just awaiting an outcome? $490 they cost
Part of this was for boring out wheel centres as AUDI wheels have a narrower hub centre. Also picked up front brake upgrade parts. They were a steal & a half at least.
Car goes in for rego inspection on 15th Dec, then back to workshop for finish of everything. Still no idea on when it will be ready to bring home unfortunately.
As opposed to 17" rims, the 18's clear strut just a little more, as they move up & away from strut the greater (higher) the rim diameter. Obviously tyres will have to be stretched so I'm guessing, 235/40R18 max? I won't know til' I get car home & fit a tyre to one of the wheels & check both front/rear hubs for clearance. I'm advised the backs will be fine. I have seen some wide wheels on the rears of these 30e's. Don't now how they fitted them on 
Concerning the front hubs fitment, you'd think they would rub on the guards but fitting just the wheel gives little indication of that. The biggest drama now is settling for the right 'ride height' so they don't rub on turns & bottom out.
I really would like to drop it 50mm but may be a little conservative in this area & drop it the 35mm as planned. My paranoia is due to fact that car in original pics showed 50mm drop & it rubbed guards, bottomed out you name it with just 18 x 8's with ET35
I need to talk with VIPAC emissions mob now & will get back......
EDIT: Guys, will get back to you as it may help others going down this same path. A very effort-ful path. PRIOR to even considering an engineers cert' check. Vehicle MUST pass an ADR emissions test$$$$
The emissions test MUST pass with car running through entire rev range, not just idling. Interesting??????who knows After I talk to VIPAC guy when he calls back ,
I'll comment again.....

Not that easy with forged alloy I can tell you. Surprisingly hard metal.
After speaking @ length with a prominent emissions testing site, VIPAR, here in VIC:
If you modify a car significantly. Alter the factory settings that effect the standard emission levels provided by manufacturer, IE: FI, regardless of whether you convert to LPG or not & therefore obtain the installers compliance plate for the engineer, you are still required to do the EPA designated ADR emissions test, prior to being provided with an engineers certificate. This is simply due to not being able to provide the engineer with appropriate vehicle manufacturer's specified emissions specs for the alteration/s (mods), as in an available factory turbo ECU, MAF, sensors etc etc,) for the car you are converting to FI (obviously the particular vehicle model was never manufactured & sold on the market with FI), you must have the emissions test performed to ensure emissions satisfy the particular standard specified by the EPA! This then gets handed to the engineer whereby he gives this part of the certifiaction the 'big tick"! Only if you FI a vehicle that was factory produced in the same model ie: you throw a turbo, ECU etc etc on a 323 Mazda that has a model in the same year sold with factory FI, can you avoid the EPA test.
Sorry for the long=winded right up but I wanted to clear the points up for any Aussie (VIC anyway) forum member who feels the urge to FI their non-turbo modeled car

How stringent the test depends on year of vehicle. Pre-June 88' test is ADR 27C = less stringent requirements to be met. Post June 88' & it is a ADR 3700 test which is harder to pass. Btw, test is $1600 a time. Takes 2 days due to 2 separate tests to pass. 1 in the morning when below certain environmental temp'. This is what makes for an extensive dynotune needed, PRIOR, to make sure AFR's are consistent across rev range or @ least on average when calculated together.
In my case, I therefore need to satisfy the guidelines layed out in the ADR 27C emissions test. obviously due to no original manufacturers specifications being met (there is no specs haha)
So. In a nutshell. As long as the tune meets acceptable emissions levels on all 3 points. It's $1600 you coff up. Also, no matter what ECU you use, factory or stand alone, it still is all in the tune when it comes to EPA acceptance & passing that part of the VASS signature that you have to obtain for registration purposes!
P.S. WORLDWIDE:"HAVE A GREAT CHRISSIE BREAK ALL"

I will be finishing off re-sculpturing the damaged outer lips on rims today. Never did get anything from the bassad who sold me them damaged. He still denies they'd been in any kind of accident etc

Anyway, has anyone down under had mandrel bent intercooler piping work done? I am having this as part of the workshop fabrication work but it is friggin expensive
Not unlike mandrel bent exhaust. I figure the aluminium bends are more difficult or perhaps involve more careful/tedious work than simple mild steel? Any comments from anyone ever having this kind of aluminium work done??

Having a reality check on the workmanship I am getting done & comparing it to the Ford XR6 kits along with considering they still have be installed = labour, coupled with fact the workshop prices are always less!
Maybe this is what is charged if you don't/can't DIY?

The Best of Mercedes & AMG
What this amounts to is too much for the job @ hand. But the main point here is inconsistency with quotes anyway. There obviously getting @ me. After all the fark around now this.......well, this was the straw that broke the camels back!
Imho there aint no way this car is worth this much hassle & expense! So, I am now awaiting another quote just to get the friggin car running on LPG, as was originally but, NA. Turboless!!! The inlet plenum will be utilised with the mixer as I'm already committed to it's build (yeah $1200 for nothing). LPG re-configured to work reliably. New exhaust system. 2" I suppose? Whatever it takes to get the ***** on the road & registered.
In the end I guess at least I have a low mileage 300E on LPG with recent paintwork, low mileage engine, rebuilt & modified running gear & all engine bay parts etc. Not my dream build, but hassle-free for the unforeseeable future...........not alot for the over $15k it will have cost me by the time I bring it home, although this includes $6500 being original vehicle purchase price so, $8500 I guess for all the work to get this sucker back on the road! Then I have the wheels/tyres or brake upgrade to do but I'll sort all that.
Considering the Merc's I can land nowdays for similar money as what I will have spent on this 300E, this has definitely been a low point in my life & one I want closure with.
Can't blame the car when, it arrived in the condition it did & a choice was forced onto me to either dump it or try & salvage it. Then, ideas op up & you trust it to a loser of a workshop.......rest is history!
thanks guys for all the support & I wish it had ended on a more positive note with a HP Merc on the road. Now it's a **** machine & I gotta move on from here........
Tim
The problem now is the $4k I payed them months back ($2100 for the turbo was included in that) in progress payments to keep the ball rolling. So with just a quick recap on work done:
a) Engine block tapped (turbo oil return), then fitted along with engine access' & also running gear fitted = $1k tops?
& work to be done in the next month (hopefully) to get it registered:
b) New full exhaust system = $5-600?
c) LPG set up including new mixer & condenser = $1k tops?
d) Custom inlet manifold & fitting with mixer etc = $1.4k tops?
e) Tune = $?
So that's $4k already really........@ least I owe them nothing if this is about right for costing
I will be speaking with them again end of next week so I'll know better how it's all coming along
couldn't take it anymore
Spoke again with workshop. Discussed another option to get this car BOOSTED!!!!
Seriously, I can't handle the turd NA! I would sell it to a gay boy & buy a friggin worked Ford XR6
actually in all honesty I have a sore friekin neck from sitting on both Carsales & EGay searching out Aussie muscle BA XR6's & XR8's .....................then..........I had to go to workshop to pick up some screws I need for my MX6 interior (mistakenly taken along with nuts/washers/bolts for the Merc) &.......looked HARD @ the ol' beast one last time before contemplating pissin it off to a new owner :o I'd had enough of the workshop expense bull****! So, says I, what can be done to get the bassad boosted, forgetting the insane expense of the EFI & just going with the already installed LPG? Even a 2nd hand Garrett for now? I don't care! Use the old intercooler & piping etc...
So. Here it is! A couple of weeks & hopefully the little bugger will be ready to take down & register. Then, either I have the turbo work completed or I do it myself. Either way it will be boosted haha
I'll work out the details after it's on the road legally. First things first! Basically it will come home stock LPG (all refurbished up & nice) with the custom plenum & TB (this will be used later for boosting = no waste of $$$'s) & just a 2nd hand zorst system & whatever bull****'s needed to get it on the road, @ least it'll be economical & different again
sigh*.................
The original install was with what TT supplied for fuel enrichment.
It consisted of Hobbs switches and a piggy back controller to fire the two added injectors.
It didn't have any consistency in maintaining the required boost AFR.
I did a great deal of research and decided on the Split Second controller on the advice of an associate who races older Saab turbos with CIS-E in SCCA sedan events.
Worked great.
A lot of time was spent on the dyno and road testing to establish the best fuel map.
Had to make cat converter changes as it rattled two sets of 500SL cats on the dyno.
Ended up with Magnaflow spun metal cats and picked up 11HP...
The hours include suspension and exhaust work...
More then bolt on a "here's your car"...everything was tweaked to get the proper total performance.
My comments on any thread are an attempt to dissuade the less experience in thinking that they can achieve something on the cheap.
There must be a few threads started everyday by one who wants to boost a M103/M104...
Just don't like to see young kids who work hard spend money with no positive results.
I respect what anybody does...but I've yet to see a dyno chart posted by those that claim "mega hp"
Same for 1/4 mile time slips..
Street racing is one thing but it proves nothing about how much power a car has and if it can plant the power to the road.
Important to see the shape and area under the dyno graph lines to see if the power is consistent.
I might be hard headed but I find it difficult that a M103 with stock valve train can rev to 10K with valve float.
I'm not a kid..will turn 62 next month, but I know how hard it is to "work for your car' when young.
I care less about being popular if it means encouraging a young guy to think through what he's committing to !!!
Tim...
It will be no longer two tone once the all steel widebody build is complete...
All Signal Red with satin black trim.
Will have the period Recaro C's and the Atwie Silberpfeil AMG steering wheel.
My attempt at "time travel" !!!
The finished build will be what AMG offered in it's 1987 catalogue.



Heres a link below. Looks bloody close? What if you used the Ford axle shafts? Or tailshaft too?

Looks like car won't be too long now before I can retrieve it from the infamous workshop
Throttle body is being fitted to custom inlet plenum then, off to the powder-coaters for a nice matt/satin black, to give it a stealth look from the jerks in blue here. This will go for all go-fast bits inc IC piping
I should here from them in about a week, prolly longer with their track record lol. Anyway, progress all the same!Been looking into twin scroll hot sides & zorst mani's yesterday & today. As long as the workshop takes back the GT35R that they said they had a buyer for, I will most likely be getting the smaller, better adapted for my driving needs, GT3071R. This turbo has a smaller comp wheel but good turbine efficiency (basically the size ratio between the comp wheel diameter & turbine wheel diameter). I've got a supplier emailing the states for a twin scroll t3 or 4 flange zorst housing to mate to the GT30 guts. Will prolly go with the billet wheel & ceramic bearings, as with the previous GT35R I bought. Will be using the smaller hotside trim to to aid in spooling. The billet wheel will spool better too & being twin scroll, along with the twin scroll manifold, will make use of the pulse cycle of the exhaust valves = very
Also, using a twin scroll, because you split the hotside flange diameter in half (split pulse), you can go bigger on the hotside A/R hehe 
I kinda envisage mating the older twin turbo philosophy with a modern single turbo. Gain the low-end pick up whilst still having good mid to top power using the twin scroll design. This allows better scavenging of zorst gases & better efficiency/economy. Something I've always been about from the start!
I'm determined to get this 300E up & off it's *** swiftly. Doing all work myself except for fabrication work. Spending $$$'s on low-down performance rather than HP figures. I want the best 0-60 time I can possibly get on this dinosaur LPG set up. WHo knows, may be a fun thing when it's finished?
My only dilemma timewise is I may have to shelve the actual fitment til' I move in about a year or so up to Queensland, where I'll have to get another RWC see? I may do the fab work & stuff in the meantime to keep the project going along @ some pace.
May even position the turbo 'underneath' the zorst manifold to hide it from view as opposed to on top as before? Hmmmmm........
I'm stuck with the GT35 turbo for now. They never sold it off.....:o
So......as it stands, car will be arriving home on flatbed somewhere around lunchtime here today. The beast comes back haha

So now begins the pita work here @ home for me. Alot of niggling things to sort from here. Basically I want to do things step by step. First gimee an exhaust system up using stock manifolds. Next, purchase & fit a new LPG evaporator. Then, re-connect all the gas lines same as they were prior to going to shop. Re-wire stuff in bay & sort the ignition system out. Replace any lines, vac etc. Basically get it running!

Once it's up & running next is to swap out the front brake assemblies. Fit new springs & maybe shocks if they're stuffed?
Then move on to powder-coating the wheels & fitting new tyres. Then gimee guards, fit spacers, whatever it needs to get them to fit.
Fit the sound system and then go from there..........
Anyway what's new huh?Now that I am stuck with the new Garrett I need to rethink how I am putting her back together........due to turbo supposedly being sold off for me @ workshop (hat's new?) I was going to simply fix LPG set up for now & get it going stock for RWC & rego. Now I have to rethink plans again.
If I do end up turboing it now, I don't want to waste time/money having to redo it again later for boosting. May be better to do it now & get it over & done with. Gather up bits & pieces I still have here & piece it back together :o Yeah fun

At least I have it away from the work shop!




& they didn't even bother to make up a throttle cable bracket for me as they stated they would (what's new?) as I also need a new cable fabricated somehow???????? No idea @ this stage how to do this

This Ford below uses a very similar inlet plenum to the one I had custom made only, mine has longer runners as I have more room in my bay:

This 2nd pic shows runners similar to mine:

God you gotta luv these workshop experts don't you?????? Why do they breathe our air

Transmission guy that rebuilt mine said it'll be OK sitting around.
New LPG workshop guy said engine should be OK so will comment back once I've turn it over a few times. The first time in 10 months

Off to Autobarn this morning to grab some cheap engine oil to put in engine. I may pull the rocker cover off to oil the valve seals (if I can get to them properly). Gez this engine is clean. No sludge or burnt oil marks anywhere. I remember seeing condition of the bottom end when sump was off when they tapped the turbo drain line in the block. Very clean! Looking through intake ports the valves are nice & black. Plugs where clean as. A strange normal steel colour actually
Wierd! Also grabbing some degreaser & metho to flush the crap out of the intercooler.
Next will be to scrape the head manifold surfaces ready for new gaskets when time comes.

My main concern is the water jackets & general cooling system. The water pump is a bit tighter than it should be. May change this?
Can't get over the awesome condition of the engine. Clean as a whistle. Just hope the valve seals are OK
Bit hard to tell until it starts up & rns for the first time. That's a while off yet. __________________
With battery removed I can hide the twin LPG converters in it's place, tucked away out of sight. I think I will be running a 2nd copper gas line beside the original one so all the LPG gear can sit in the old battery compartment. Looking from front of car all you'll basically see is the engine, turbo & intake manifold, minus ugly wiring etc
