My 95 M3 EURO Turbo build

[GasFed m3]

This has been along time coming now waiting for all the bits and pieces to come together and here are a couple of pics and a list of the stuff that was waiting for me at home during my last shore leave

86.5mm JE pistons 8.3:1 cr balaced and pocketed to accomadate bigger exhaust valves
Total seal rings
Pauter conrods
ARP head studs, mains, conrod bolts
PPF 76mm dump-valve
Nuke performace fuel rail
tial 60mm wastegate(still waiting for)
Turbowerx oil-scavange pump kit
pt74gtsdbb turbo
Autonic SM-4
1000cc delfi injectors
clutchmaster fx700

The block(3.0L euro) has been cyro treated and received a set pyramid rings, while the head(3.2L euro) has been flowed and bigger exhaust valves fitted and the crank has also been been cyrotreated after being knife edged.

It has taken quite a while to get all these bits and pieces together and I am very close to the end now, the only bits that are stil here from the previous setup is the fueling system minus the fuel rail.

can't wait to see the end result!! How much power are you expecting?

also, one question. (I"m a n00b) What does cryo treating do to all the parts?

the pic quality is bad in the last pic but if you look carefully you can see little ridges cut into the back of the intake valve

The reason I had the block cyro treated was to help with block flex and the crank was to de-stress the metal after it was knife edged

You not only have the sickest build I have seen on here, you live where the sickest wave in the wold is. Bastard!

Ho - Ly - Cow. That is sick man. If you don't get a better digital camera for taking pictures though I think you'll risk being banned.

Sorry about the picture quality but this was all done in a rush with my cellphone, my updates will be better

[SiGmA]

Damn thats sick. I can't wait to see it! Keep us updated and good luck!

[eurotekm3]

wow!...this going to be a sick build!



keep us updated with pics + vids..... PPF parts!

wich turbo manifold do have and maybe some pictures?

I was running the savspeed cast exhaust mani and intake, but as soon as the motor is put together and installed my car will be going over to a place just outside of port-elizabeth called Hi-tec automotive and those are the guys who build the noble and gt40 replica kit car and so on from scratch and all in house and these guys are going to design and custom fab my exhaust and intake mani and build a 4inch exhaust.

what power do you want out of this car

[highboostingm3]

Just noticed your 74mm is dbb! Hell yeah! Can't wait to see what rpm full boost is. This car is gonna make 850+whp!

I am hoping to have full boost at around 4k What I am looking forward to is eventually being able to turn up the boost without worrying about any headgasket issues and if I see 700-750whp i'll be more than happy with that//

S50B32 and 74 mm:

Full Boost will come around 4750-5000 rpm depending on the following variables:

Head work: porting and polishing of the head. I see you have + 1 mm valves. A very professional head P&P is needed.

A/R ratio of exhaust housing

Type of exhaust manifold: Tubular or Log Style. This effects the full rpm seriously

Runner diameter of the exhaust manifold. What is your exhaust runner diameter?

Coating of the exhaust manifold. Improves full boost.

Intake manifold design. Very important. TOTAL PLENUM VOLUME & PLENUM SHAPE?

Intake manifold runner LENGTH and DIAMETER. These 2 factors are very critical, determine at which engine speed max torque is produced. So play a role in full boost build up.

Vanos: Needs to be reprogrammed through OEM ECU. to decrease overlap. The re-programming of vanos allows earlier full boost build up. Remember our Euro M3s have big overlap which is not wanted on a Turboed M3. I had full spool around 5400 rpm before vanos programming. I have reprogrammed the OEM ECU VANOS maps and that alone lowered full boost to 5000 rpm.

on the OEM ECU, there are more than 1 map for Vanos Programming: 2 exhaust vanos maps. & 2 intake vanos maps. All 4 maps needed to be changed. I made several maps, logged on the dyno at 4 th gear.

Down pipe diameter

Smoothness of downpipe. how smooth is it?

Mid pipe diameter

Rear muffler design

Any cat converters? if you can remove them

All being ideal, 4750-5000 rpm is the sweet spot. All being out of ideal line, expect to see full boost around 5500 to 6000 rpm

Main point: one can not optimize all of these variables at the first time.
You need to work a lot.

I own 2 x E36 M3 Euro Spec M3s, all twin turbocharged

[daytona M3]

alwaysturbo(mert?),do you have pictures of it and a dyno?

[AjRose]

Sick build

Any more info on pyramid rings? I cant seem to find any info on them

[hockey]

so are these the twin mert turbo m3. lets see some pics and dyno like daytona ,3 said

I am not to worried about the vanos as I am using the 3.2l head with the 3.0l cambox so I only have single vanos and my feeling is even though the autronic can run it, it worked fine with my old setup the way it was with the stock dme running vanos and that was with a T72 journal bearing+ log style mani and a standard 3.0l head and I saw full boost at around 4700
....
So it is on the basis of that, I am assuming with the pt74gts(DBB)+ tubular exhaust manifold+ 3.2L worked head with bigger exhaust valves and and and all the improvments over my old setup I think it is safe to say full boost by around 4K.

There are alot variables when it comes to the options there are to choose from when doing a turbo build and I can only hope I have made the correct ones, but thank you anyway for posting and I really would like to see a couple of pics of your twin turbo setup
