The 15 Y/O Turbo M42 Build Thread (Now Holley EFI Terminator X Controlled)

[jintermont]

you sir give me inspiration to tarbo my m42 :-)

I drive mine daily so my tune is mild, I wanted it to last. I would love to add more boost and make more power, but I don't want to be fixing broke parts. I have a tune that makes more power but with my gearing doesn't benefit in any way. The current tune is much smoother and defined power band. I think with your plan of 15-18 psi, you will make 275whp or more.

If thats how it is, my 15-18psi idea may have to be toned down a little.

haha... NOT. ;)

considering the weight of 318's or e30s in general i cant imagine what that kind of power will feel like.

Not gonna lie. I'm diggin' the pink. Maybe get some BMW pink round emblems?

I wasn't having a huge problem with traction as long as I was going straight when I had my summer tires on the car and teh 4.10, but first gear was really too short to even do anything. I would shortshift into second around 5k rpm if I was accelerating hard. I'm hoping 3.73 will be long enough to let boost build but not so long that I'll have to work around the (now much larger) powerband.

So I take it you still have the stock ECU in the car? I would just take your time, just so you don't risk it...

As far as my oil feed line goes, I ran an oil line from the factory oil pressure switch to a t-fitting, and the turbo feed and the pressure sender are run from there. The fitting i mounted to the frame, so I don't have to worry about the vibrations that are kinda notorious for killing those senders. VDO sells a sender that has a post for the gauge and then an on-off 7 psi post for the idiot light, so I can keep the factory functionality.

I can haz pink wheels???

But seriously the only e30 that could pull off those wheels. Good thing mines exactlt like it. xP

yup stock ecu for now. im gonna keep it low low boost. like 5 psi max till i get it on a standalone.

^^^ Aww!! Fuckin awesome!!

[e30guydownunder]

Awesome build on the engine mate. I'm going to go with a fresh Head Gasket and some Big head bolts first up. I'm aiming to get over 150kW and keep it nice and responsive. We shall see. With my car weighing maybe a fraction under 1000kg's not like I need massive power :)

Was planning a balanced and forged build, but the coin is a lil out of reach currently and not really necessary for the power I'm talking I recon.

In for more progress on this thing!
