My 2.7i Build

[nando]

haha, yeah. there should be 2 wires going to the coil.

so it runs now? be careful breaking in a boosted motor on Motronic..

[SpecM]

so.... it runs now?

[Jordan325iC]

Well, it doesn't run yet. I realized my problem while I was at the library. Unfortunately I won't be able to work on the car till Wednesday once I'm finished with a few tests.

It is killing me having to study right now instead of driving to the garage and finishing this thing up.

Nice build man!! I am also just finishing my Turbo setup on my M20. I am quite amazed with the break-in advices given above...!!! I never ever heard of anyone saying you should drive a new engine hard!!

What power do you expect to make? Also...abit off topic...what do your M20 Turbo's down there do on the quarter??

Keep up the good work!

I'm hoping for 250whp @ 10psi. Might be a low goal, but my setup isn't optimal so I'd be happy with anything.

Uh, turbo m20s run from low 14s for little 6-8psi setups to low 11s for the 400hp monsters.

Ended up being a bad engine ground. Cleaned it on a whim and she started right up. She's running great right now, I've put about 85 miles on her. Changed the oil today and there was no metal specs that I could see, so all is well.

engine ground huh wow glad it is running!!


Now its time to race or spank my m42!!!

not to be a noob but whats welding a head and O ringing a block mean? Is O ring the block essentially putting O rings on top of each cylinder instead of a gasket? doesn't metal to metal not seal completely? and whats welding the head? close the cooling passages?

Oh jeez. Those are all very noob questions, but for the sake of the proliferation of knowledge I will answer them all. I don't have time right now, but I will do it on Friday.

Just thought I'd update this old thread, for posterity.

Did the break-in. First thing was ~20 3/4 throttle accelerations/decelerations in 1st gear. Essentially I just drove with constantly varying RPM for the first 100 miles, with lots of engine braking. I kept it under 3500rpm during this period, and I would gradually raise the RPM limit 1000rpm every 100 miles or so. Started boosting slightly after 300 miles. Once I hit 500 miles, I started using full boost. Oil change at 10, 85 and 500 miles. This is all from memory, but it sounds right-ish.

The compression test I did today (700 miles) went well. It wasn't a very scientific test because it was impossible to count the number of cranks when the battery was fully charged (starter would spin too fast), but it did give a rough estimate.
133 140 131 129 130 135
Even these rough numbers were within 7%, so things are OK in the engine thus far. I am pleased.

You should really check valve clearances after a few hundred miles. Mine had gone out-of-spec during the first 500 miles.

Engine bay (needs a bit of cleaning up):


The car:

Hawwwwwwwwwwwwwwwt

holy rack 'o' vaccuum lines batman. Be careful with those smoked tails, I am running a set like those, and less than 5 days on the road, someone ran in the back of me. No damages, but still....

i honestly dont see how people rear-end other people... i mean, if your obviously coming up on a car thats moving slower than you, slow down, brake lights or not...

OP, very nice, hows it feel with the turbo? thats a tiny air filter lol

if you value your car, never underestimate the stupidity of others on the road.

[Jordan325iC]

Yea, there are a lot of vacuum lines. All necessary however, and only 1 "tee" in the whole setup (FPR and RRFPR share). I will clean it up in the future by changing those two straight vacuum barb fittings to 90 degree fittings.

Made a $150 order to Summit today, should address a lot of the issues. Nice big air filter too.

As for the tail-lights, I got them in a junkyard while traveling for really cheap. I primarily drive the car at night (camouflage, you know) so it they're fine. They aren't as dark as the picture makes them out to be.
