12 PSI should get you pretty close to or exceed your goal of 1,000 hp if you can control the heat. The 156 engine responds well to boost.

Thanks BlownV8. I do have to assume that SLS has the forged pistons and SLS buckets stock. That is something I'll have to do pushing past 600-700HP I think. Weistec indicated SLS buckets are pretty much a must since stock ones fail pretty frequently.

Weistec's forged pistons are ridiculously expensive though so we'll be looking to have some made after this first stage unless someone knows a better alternative (EuroCharged ones are even more expensive).

 

The only ones I know that will work long term are made by Mahle or Koblenschmidt. I wouldn't trust any other pistons. Don't cheap out here. You will.regret it.

 

^+1, if you are going to take the engine out and build it out then do it right first time so you dont have to do it again... going cheap on internals will save you a bit upfront but down the line will cost you a lot more if you have to do it over again

 

Interesting project for sure, can't wait to see what you guys come up with. If you need any tuning help let us know

 

Thanks you Gaspam and BlownV8.

I wasn't planning on cheaping out at all . Just looking at options.
I'm really grateful for the two companies you listed.

Do you know if they would manufacture for 1 person though if we had specs? Or do they only work through distributors in bulk?

 

Mahle made two custom pistons for my Ducati build years ago so unless something has changed, they don't require distributors or bulk orders.

 

Do you recall how you contacted/ordered from them?
I shot them an email.

 

I don't recall anymore, sorry.

 

The last time I checked the V8 forged pistons they were in excess of $4k. However, I'm telling you from personal experience. Run Mahle or Kolbenschmidt unless you plan on installing sleeves. Really, sleeving your engine may be the best option and could also be cheaper in the long run. JE, Weisco, and others can easily make great forged pistons to run in an iron bore.

So you will have to pardon my complete ignorance here.
Sleeving the engine is not something I'm familiar with? I saw that on MAHLE site but was not sure how/what purpose it serves.

I did send them an email earlier today and waiting for a response.
$4K is not too hatefull if it gives me stable 1K HP power potential but I wanted to explore what options I have.

Weistec sells theirs at $5.5K and when I asked would they give me a discount for the full build (+ SLS buckets, head studs, rest of the bolts -since they are torque to yield, gaskets, bearing assembly) -- basically almost 10K in parts alone -- I got a pretty hard NO ...
So I'm looking elsewhere.

 

Do some research on Darton MID sleeves.
That is what we use for the E55 engines

 

That is a very interesting concept.
What kind of power are you pushing with those in an E55??

 

MID sleeves can hold 1000 plus. A lot of GT-R use the same sleeve but in a different size.

 

So does that mean I can bypass the forged pistons basically? Since the sleeves will hold compression and integrity of the cylinder and only worry about valve buckets (notorious on these engines).

to others: Not trying to cheap out I promise just looking at different approaches.

I also found this lol

No, I would run the forged pistons too.

I feel you would be much better off buying a newer E63 and upgrading the turbos. You will get better results, the engine and ECU is made for boost, and will be cheaper in the long run.

 

If I was going to run forged pistons whats the purpose of the sleeves than.
I'd have to bore out my cylinders and pop those suckers in.

I can see doing that well past the 1K HP but I'm pretty sure the block can handle 1K (correct me if I'm wrong here).

1K in my mind will need: forged pistons, valve buckets, fuel sysyem? (pump, rail, injectors) and built tranny. Anything I'm missing?

 

Just got off the phone with Mahle.
They can do 40/32 alloy forged custom pistons. 6-8 week delivery.
225-250 per piston including pins and ring.
They mentioned I need to fill out a data sheet so I was wondering if anyone has done that before with them for the M156?

 

Did you tell them you need Alusil compatible pistons? Seems very cheap.

 

I didn't know if it was Nickelsil or Alusil. I think he assumed Nikasil

I'll email him tonight.

 

Did the measurements today and looked at all possibilities.
A thought occured about making an intake manifold and integrating cores there - similar to supercharger setup.. sounds fun and expensive lol.

Going to get rid of the big resonator in the middle to open more room for x-pipe. keeping stock cats for now.
Thinking of creating more volume with some crafty fabrication for the meters on the intake to increase their range as well.

Love watching Will's mind spin and work.

Oh, got a dead bird out of my radiator. It was nice crispy and dry. No clue how it got there since there was no damage to anything.

Turbos are sill being manufactured but getting close to getting our hands dirty.

ALSO picked up a kick a$$ set of idler pulleys and lower weigh crankshaft pulley from Ultimate Performance and Detail (ultimatepd.com).
Thank you Shardul! Looking forward to getting those bad boys and installing them. They will definitely help with the spin up.

I will have ROW airboxes available for sale. If anyone interested PM me. Had them for less than a year.

 

Got an answer and datasheet input from Mahle.
Pistons are not affected by bore material but ring are.
Silly me I assumed the price included rings. I guess it doesn't.
In any case here is the link to the data sheet.
DOES ANYONE HAVE ANY CLUE about any of these:

If you got this information from a Mahle rep, he is somewhat clueless about the pistons but he is correct about the rings. The bore material has everything to do with choosing the correct piston material. If you are running an Alusil bore, you have to run coated pistons. If you run an iron bore or Nikasil, you don't need coated pistons.

 

Yea I know about the coating. I'm wondering if that is what I need to specify on the data sheet- there is a coating field. I guess I'm not sure what all they offer Ferro, moly, whatever?/

 

Go with the Ferro.
