My turbo M3 build thread!

[M3_MadBimmer]

The car is getting very close to completion and i figured i would start the build thread now and hopefully in the next coupld weeks it will be finalized.

Little backround story,

I had my 98 estoril/mullberry m3 and never drove the damn thing, always wanted to boost it. I was away at school and the car was just sitting in the garage so i decided to sell it. When i sold it, shortly after bassmaster on bf.c was selling his 95 turbo m3 on there. I though man, pretty good price, i have no time to do a build at this time, why not buy it. So i flew out to NC and drove it back. Put a few thousand miles on the car and needless to say, everything on the car was sloppy and the motor gave out, windowing the block with the number one rod.

I've always stayed in touch with the buyer of my estoril and he actually was telling me that he might be selling the car. I cam up with the perfect plan...

I bought the estoril back, yanked the motor out of it and threw it in the 95 which is now my daily driver. I also replaced ALL of the suspension, brake lines, and brakes on the car, it was very poorly maintained by the NURSE bassmaster on haha. and i went to town on the estoril.

Out of all the parts that were on the 95 when bass master boosted it, i only used a few to go into the estoril. PWR radiator, ebc, aa DSB, FPR, oil distribution block, crankshaft, stewart water pump, and aa 90* TB elbow.

I’m now finally doing what I wanted (and should have) to do initially. And that is make a completely custom and proper turbo setup on my estoril/mulberry sweetheart using all new/quality parts. I’ve spent roughly about $25-28,000 on parts for this car. Only labor I paid for was for cylinder head work, block machining, and getting camshafts reground.

BIG THANKS to JT (Got psi) for doing the engine assembly, we were supposed to do it together, but
with different schedules etc he basically put together the whole thing. Also sorry for the lack of engine build pictures, but my camera got stolen with the pictures on it 

Exhaust:

- Tubular T4 top mount exhaust manifold
- 3” exhaust all the way back (no mufflers)
- Tial 44mm wastegate
- Wastegate piping tied back into the down pipe
- Turbine housing, manifold, DP, and WG piping all ceramic coated
- All v-band connections


Turbo/Tuning/Electornics

- Turbonetics T66 ball bearing turbo
- Converted to OBDI and using TRM tuning, multi-tune setup for 93, 93+meth, race gas, and anti-lag
- Aquamist HFS-5 water/meth system using two 1mm jets
- Custom 8 gallon meth tank
- Blitz sbc id III electronic boost controler
- PLX wideband
- Stri-Racing boost/vacuum, oil pressure, oil temperature, and water temperature gauges
- Aquamist gauge in the headlight switch location, A/F ratio and boost/vac gauges mounted on the steering wheel column pod, oil press/temp, water temp gauges and EBC mounted In a custom sunglass holder

I was initially going to go with ICS/Nick G factory obdII tuning until I realized the m50 block did not have a hole in the back for the obdII crank sensor. Plus the fact that they couldn’t do it remotely brought the problem of shipping my car over there…what if the car did not want to run, or had some other problems. Plus I wanted to properly break the engine in. Geaorge was very generous and a huge help with a bunch of questions I had. I’m really bummed it didn’t work out.

I’m sure I forgot some things but I will update as I progress. I’m hoping may 1st it will be done!


Big thanks to JT for being a huge inspiration for me to even start welding, and putting together my motor.

Mike Radowski for supplying me with parts and answering a ton of questions.

George at ICS

TRM, hopefully you guys will bring me to the promised power goals that I have!

I had already done it.

[Arnel]

Wow, nice job. That's a lot of work...certainly much more than I'm willing or even capable of. Congrats and enjoy.

i couldnt wait anymore, but it's almost done anyways

[ZoHeB318]

I wonder who was there when JD Moto took those pictures....

Luke did you build that manifold yourself? It looks amazing!!!

[r0nd3L]

That is one badass project.

The skills some people on here have amaze me!

the twin

and yes, i made that myself. Bought the collector and flange seperatly though.




update, installed fuel tank and mounted the bosch 044 inline pump.

[StreuB1]

is that a sheetmetal screw through your floor???

[ivopivo]

Awesome Luke!

You must be donating lots of sperm to keep up with that cash flow man haha

Can't wait to see it done!
