DTR's Turbo'd M52 E30 track/street Demonstrator

[DTRguy]

I run 225/45/17s in the front on a 17x8 0 offset with spacers ( I hit the frame thanks to my tie rod spacers) and 245/45/17s out back on a 17x9 -5 effective offset rim. Rear end is a 2.93 lsd

I run 15psi now (350whp on a cracked mani) and have yet to break anything. Although my build is no where near as extensive as yours. I'm just a 0.140" mls on a stock M50 NV.

the 245s lose traction if I floor it in just about any gear. :-D

I am guessing right now I am at 320 maybe. your tire gear ratio is smaller than mine (shorter gearing slightly) My engine is a stock 2.8 NV with gasket and head studs

I'm just screwing with you. 8psi on my M50 was enough to spin my 245s without too much effort. Almost scares the crap out of you right? I love that feeling. Gives me an evil cackle.

I hear ya... yeah, I have the timing conservative, and the fueling a tad rich. What rear gear do you have? What size 245 17 or 18? I am running 2.93 with 18's! It doesn't scare me so much as much as I am wondering if something is gonna break LOL

tsk tsk. your break lining light seems to be on.

lol good first vids! I'm jealous!

got an ETA of when the tune will be done?

I need to loop the damn sensors off and well yeah... had to steal the good ABS sensors off of this car and put on my other m50 car (daily) And the ones that I got came from the junkyard. One is good I am sure... the other maybe not so much. Brakes on the car (sans ABS working) are insane! Almost too powerful! No real ETA on the final tune. Trying to locate a boost solenoid or an N75 valve for the ECU to control boost to up it as of now. Not into manual boost control. Right now I need to focus on the bodywork, and getting other work in the shop done to pay the bills!

Saw the car today, heard it run. It should be silly.

Kevin. make sure you guys have some kind of video setup on it when you go to Mid-Ohio.

Yeah Dave I am sure we will somehow.

Here are the recent videos and a pic from yesterday showing the engine as it looks now basically all complete!

Fuck the Hood. You have to show off what you have under it.

[DTRguy]

This must be updated.... looks pretty sick! What are the specs on the m50 internals?

It is an M52 2.8 stock, ARP head studs .140 HG. m50NV head (I know right cheap setup that'll probably grenade)

For an update... IT RUNS... and well kinda DRIVES! I have to rework the intake plenum BOV location slightly so that it clears the hood... so no hood for at least today. But here are some pics to catch up this thread.

You Sir, have a great thing going here. Eye-candy!

What throttle bodies are you running?

They are extrudabody ITB's... Here is a link to their manifold for the ITB's I am using...

Ridiculous. Pretty sure nothing else needs to be said! Well, other than I'm jealous of your budget and fab skills.

Thanks! Don't be jealous of my budget... I'm broke! I have been planning and organizing, parts collecting for 3 years! The fab skills... I appreciate the compliment but it is what I do for a living. That is why I am doing this car to show this fact off ;)

Started working on the wiring...

My m20-m50 custom adapter I made:


And how I accomplished the coil pack/injector harness:
