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

[Il Duce]

I've seen this thing IRL, not when it was turbod though. The stance is better in person than pics could ever show. The wheels are actually fucking sweet too. Good work man! Glad to see you got the turbo on.

[Dj Buttchug]

thanks for all the comments guys.

Looks nice! glad to see you getting closer to a boosted M42 :). Now you, me, e30guydownunder, and schnitzer all will have running cars...if I wasn't on the wrong side of the country, I'd say a meet would be in order haha.

And I really wish I had low compression/more boost, and a GT-series turbo. I can only imagine what that would be like over my somewhat more home-brew build...

What diff are you running, by the way? I don't really trust the small case diff, and I'm having a hard time putting power down, so I'm in the market for a 3.73 LSD.

There is a slow growin population of us scattered across the globe :)

To be honest I have NO idea how this thing is going to run. im running a 2.93 lsd medium case, so will see how that goes.

I know for a fact im going to have serious issues getting traction. will see how low boost like 5psi on the stock ecu feels.


Video up finally

I have a small case 4.10 with little to no 1st and 2nd gear under boost. I'm switching to a med case 2.93 to help boost sooner and decrease rpm on the freeway with my 16 x 9's :) boosted m42's rock!

i will one day join the turbo m42 world haha. to all you turbo m42 guys, what is the easiest way to supply oil to the turbo?

[ethrtyiS]

very nice. now we need a video of it driving.

[gsxrcop]

I tapped into the oil filter canister with a tee, feeds the turbo and gets pressure to my gauge.

here is where i ran my feed. there are two places to get oil one is here, the other is on the rear of the head. There is an oil port there as well. It is the same size as the one pictured here. this isnt my engine btw


Problem tho. No one in the world makes a 12x1.25 thread fitting(which is the measure of the allen plug) out to a -3 fitting.

Therefore one has to be made. I tig welded a custom fitting to make this work. i can get pics.

[dkbmxer002]

nice, i will probably try to use the factory outlet.

[dnova89]

Nice

[gsxrcop]

Just wait until you get a good tune, then the fun begins :) What kind of rpm's you turning with your wheel combo and the 2.93?

I did this same deal, with the same size bolt on a 24v VR6. I just used a 12mm banjo fitting with a -3an fitting off that. Worked like a charm. Got it from JEGS.

im turnin like 2500-2600 r3v at bout 80mph on the freeway. 1st 2nd and 3rd are longggg gearsss.

[gsxrcop]

That is where I would like to be, boost should make up for the longer 123 gears. Mine burns the tires the first three gears under 10 pounds currently.

[Mike The Bavarian]

that thing sounds real nice.

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

haha... NOT. ;)
