Legoinsaniac

good God!

I'll be looking forward to your progress reports on this one!

Saijin_Naib

so you need custom fabricated headers and stuff right?

jdmfiend

manifolds my friend =)

shadowgriffen

Ryan that's just plain Sick dude

Saijin_Naib

holy. is that all bolt-on or some serious ****?

jdmfiend

its all custom fab work

300EVO

Those are 4-cyl. manifolds or are you intimating that the company/person making those will make one for you? Will they then offer them for sale for all M104 engine owners? I also have a Wald V4-kitted 124 that I'm gutting & caging and would be interested in going that route.

jdmfiend

yeah i know, those are evo turbo manifolds.
the company doing my manifolds is 1fab but their site it down so i found some of their work online. when i come back from mexico ill go into specifics with them and see if i cant get them to build you one too and see if they cant cut the price.

shadowgriffen

1fab, you mean like the same peeps that did some stuff for Alexbenz's Benz????

shadowgriffen

any pix??

300EVO

Thanks, definitely interested. Looks like you sized the turbo just about right.... not too small and not ridiculously large.

mgw_300e

Ryan, what's your total cost look like and what kind of performance gains are you expecting?

YNVDIZW124

GOOOD LUCK on that project..

Have you thought about what your going to do about the ignition system, fuel injectors and managment, and intake manifold?

hellah fresh

Nice! Hmmm... with stock internals you probally can run no mor then 11-12psi?

ZorroAMG

Yeah , after you change the electromechanical fuel injection to electronic, then you can think about turbo'ing it.....otherwise, RIP 300E, oh and try more like 5 or 6 psi on stock motor...

300EVO

His car is a '95 E320 which already is electronic fuel injection. Either could be turboed. You are right about pressures however. You could use a rising rate fuel pressure regulator to supply the extra fuel demand and the stock computer and existing knock sensor. Since he is using an intercooler, he might get away with a little higher than 5/6 psi beyond that he needs some more detailed fuel/ign control.

mgw_300e

Are you sure it's that little? The blocks VW used in the Rabbit could take 15 psi before you'd have to start reinforcing it. (400hp, too)

I never did it myself, but I read that over and over again. I imagine a MB engine would be able to handle at least that? I don't know, but I am curious.

300EVO

I've seen these engines turboed before but don't know of any long-term cases. From what I've seen inside my own motor, it's built like a tank. As boost pressures go up, it's critical to guard against leaning-out and detonation ( bigger fuel injectors; ignition retarding; lower compression pistons....). I would like to know as well but could be an expensive R&D process.

mgw_300e

weren't you researching this stuff a while back? what did you find out?

YNVDIZW124

It's easy to turbo a mustang because you can run a aftermarket igniton and fuel system. Also the 89-92 5.0 engines come with forged pistons right out of the factory so you can either give it a 150 shot of nitrous or 8-10psi of boost and even more if you rebuild the bottom end. First he should start by porting and polishing the heads and do a 3 angle valve job. If he could fabricate a custom intake manifold and plug the ports where the fuel injectors go that would be one big step to making alot of power. That way he could run basically any fuel injector and fuel managment system.

Using the mercedes computer i think is a bigger waste of power because after you turbo the car you have to tune it on a dyno and get the right fuel/air ratio for max power.


Now if you can get a supra engine with a single turbo conversion and a big shoe horn that would make your car the biggest sleeper in the united states.

If you put this in your car you'll be my hero!!

This is in texas too so you can buy this and forget the mercedes engine for $1600 it's a steal!! 300hp 415 lb of torque!

300EVO

I'm not sure of the head work benefit as it is already a twin cam 24V so that's probably money better spent elsewhere. You may be right about the intake as most of it is thermo-plastic and possibly a weak link for serious pressure.

YNVDIZW124

I would think on a turbo set up you would benefit by porting and polishing the heads since the flow of air is smoother and faster. I don't know the price so maybe your right it's not something you can't live without but if your going all out why not.

I haven't seen many high perfomance internals for these engines so i don't know how can you rebuild it for max psi. That's why i say just get a supra engine because the aftermarket is huge compare to mercedes.

turbo kit on 3.2l = alot of headaches
supra engine = alot of power and some custom fab but not impossible.

hellah fresh

Wait a minute! Yes i have heard that people have been putting supra motors into a benz. I actually heard it from my friend that came from Thailand. There was a 300e that had a twin turbo setup in it. I wonder how much trouble you have to go to do that..

neanderthal

if youre gonna do an engine swap why not just do a small block chevy.
theyve been turboed and supercharged and modified more ways than a supra engine.
they are cheaper and lighter.
and probably end up getting you the same power for the same price but with more reliability if you start adding crazy boost.
