My present daily driver is a E36 3251 with a supercharged S50B30. I currently boost to about 8-9psi with my ASA supercharger, TSI/Powermod piggyback, Evosport pulleys, full Supersprint Euro exhaust system, 3.38 LSD, LWF, UUC shortshifter.....


Now I'm ready for a bigger project....turbocharging another S50B30 that a bought from Alex about a year ago. So far I have bought:
- 8.5:1 Wiseco forged Pistons
- forged Arrow conrods
- crankshaft bearings
- lightened, balanced crankshaft
- new stock head gasket
- tubular turbomanifold(made by Jon Volk)
- water injection kit


I plan to purchase next:
-CF intake manifold (hopefully with 3" inlet)
-Precision SC-61 turbocharger
-3" intercooler pipes, TurboXs BOV, and FMIC
-Powermod piggyback
-Tial 38mm WG

I'm planning on running 1 bar boost(I'm not sure the stock HG can hold more boost).

Can anyone give me input on how to acquire:
- stronger head bolts
- stronger HG
- stronger clutch

I would love to get the input from a member who has done FI to a S50B30 before.

for the HG talk to Erik from Bavariacars, he can hook you up with a custom one that'll hold boost, also provides Powermod piggyback.

OR

you could bite the bullet and o-ring the block

If its a right hand drive car, Mrblonde on here has done this but to an S50b32. If left hand drive, another good port of call would be PPF (pure performance factory in sweeden??) or i see in forced inducton section horsepower freaks are doing some good things with the E46m3of which hadware would be similar (except for tuning).

Do you boost 8-9psi in S50B30 with totally stock internals? Do you have an intercooler? Do you use an water injection? It’s quite interesting. Few months ago I read somewhere about Turkish (not DA Motorsport) project. The owner boosts ~0.68bar in totally stock S50B30, but he has been having a lot of problems such as blown headgaskets.

A friend of mine used a stock clutch and a pressure plate from M57 (3.0d), when he was boosting 1.0bar in his european version of S50B30. He said me it was enough. That combination is enough good to approximately 600-650 Nm in his opinion.

Do you want to install a bottom mount turbocharger? If so, I think you will have to buy a scavenge pump.

You should also don’t forget about injectors and a fuel pump.

What lightened & balanced crankshaft did you buy?

8-9psi from a vortech wont need lower compression..
i've seen it on 2 e36 m3, one S50B32, on S50B30
with no intercooler i might add,
but the car was becoming very weak after a few runs so they installed water injection and it worked out fine
but the stock clutch wasnt handling the torque so they had to change that

By the way can somebody put a standard on internals and headgasket,
i hear from one place stock internals can hold ~600bhp
and so can stock gasket with thicker sandwiched plate (to lower CR)
(the south africa guys)

in other places people say more than 0.9bar and the HG will blow, and internals MUST be replaced...
two totally contradicting theories! :/

Okay, regarding my supercharged S50B30, I boost 8-9psi with stock internals. Yes, I'm intercooled but no water injection. No HG problems yet.
I use the 120mm supercharger pulley(the smallest available from Infinitas)on my ASA supercharger. The car does well on the highway, but I need to do a lot more tuning as I am a bit too rich in fuel in many areas.
I have Sachs clutch, pressure plate and LWF.
No dyno runs yet,but before boosting I dynoed at 215whp, so I expect about 350whp when I do dyno.

Now, on to the turbo project.
I plan to do a bottom mount turbo, so yes I need to buy a scavenger pump.
I have 42lb/hr injectors already, and an extra inline Bosch fuel pump.

The balanced and lightened crankshaft is a Motorsport which I bought from Mert Dastan(Da-Motorsport). I will weigh it when I get a chance.

I will call Bavariacars to get some info on the HG. I just need stronger than stock, because I already have low compresion Wiseco pistons.

i thought Mert Dastan turned out to be a scam artist ? i hope for your sake that crank you have is really B&L'd! must have cost a small fortune

Thank you, cactus, for reply. Do you have any pictures of your set-up? Is it custom made, isn’t it?
An extra inline Bosch fuel pump is a good choice. You will have better flow. What is this Bosch fuel pump? Is it a stock one?

What did they change with a clutch? Do you know?

Is 8-9 psi from a Vortech safer than 8-9 psi from a turbocharger? Why? I thought the turbocharger has better an thermal efficiency. How much horsepower did those M3 achieve?

I have also heard that more than 0.9bar of boost will cause a headgasket blowing. It’s hard to put a standard on internals, because of its current condition. I know from other people, who have quite huge knowledge about turbo charging S50B30 that the weakest parts are a head gasket, rings (they can’t stand boost), pistons (they are special made to high performance NA car, are light. In Swedish opinion pistons are enough good to ~450 HP. One of them boosts 0.7bar after shaving pistons down (CR~9.1). The car was/is still OK. He has achieved ~470 horsepower at wheels. I have heard about broken drive shafts few times (for example PPF’s new project).

I know:
A fuel pump is okay to ~430 HP (all euro E36 have the same fuel pump),
Injectors to 300+ HP,
A clutch to 0.2bar of boost.

Maleckis.

about the clutch i dont know what they did cuz i didnt ask back then i had no plans other than keeping the S50 N/A :)

i think i can safely say this engine is pretty much unknown territory and a big headache to boost, i thought it would be easy but there is no accurate and reliable wealth of knowledge concerning this subject

i guess turbos put more stresses on the engine because 9psi is only at the redline in superchargers, whereas with turbos full boost hits early and stays across the powerband
right now im really regretting not buying a used vortech setup for a s50b32 a guy wanted to sell with a tuned ecu for $1000 :(
but i dont like superchargers and i guess im right because whoever installs a supercharger always always always ends up makinga turbo project afterwards and are not satisfied with the supercharger setup completely.
but if i knew turboing the car is such a nightmare i would have settled for the vortech setup cuz the price was very good

i thought Mert Dastan turned out to be a scam artist ? i hope for your sake that crank you have is really B&L'd! must have cost a small fortune


Mert Dastan is an entire new thread, so we wont bother going there.

The cranksahaft cost me like $2000 or more(I cant remember exactly). It might have been $3000. I had planned to weigh it, but hadnt found the time yet.

I will post pics of my engine bay when I get my car cleaned up(it's filthy now).

I cant remember the exact specs of the Bosch fuel pump, but I'll check on it.

Most of my parts were ordered from Mert Dastan (Da-Motorsport). I visited Mert in Istanbul about 2 years ago and drove in his '1000hp M3'. I was so inpressed with the performance(still not 1000hp obviusly), I trusted him to help me with the supercharge setup, which has eventually turned out ok so far. So my engine bay looks just like the pics on the Da-Motorsport website.

Since then, Mert has offered to help me with my turbo project, but now I know better... I'm looking for guidance elsewhere, like these forums.

cactus,

Post some pics of your setup. I've already seen DA's pics. Can you post some close-up shots of the custom manifold? That's what I really want to see.

Thanks!

Ok, I'll take pics tomorrow when it's daylight. It's really nothing special, but it beats the big-ass stock manifold.

Ok guys. I've decided to use Morristech for my fuel and ignition management. I presently use TSI in my supercharged S50B30, so it should be all very familiar to me. Oh, Daniel is a vey helpful guy.

I'm in communication with Erik fro Bavariacars. He recommends a copper HG which costs $350 and O-Ringing of head and block.

I may use an aluminium intake manifold instead of a CF manifold if Bavariacars will fabricate one for me.
