I agree, I took mine off before the install so I could be a possibility? boosting the crankcase is an easy way to force a new engine. It will exploit every little imperfection in seasoned gaskets and actually start leaks. It also can foam the engine oil in the crankcase in extreme cases.

Currently I'm dealing with pulley offsets ever since i bolted my unit back on. I shredded 2 belts now, this weekend I plan for a final adjustment (117.7'' belts arn't cheap at $50).

Kc- Nice battery relocation, I did the exact same thing. Took stock terminal leads and used a solid nickel distribution block, worked great and i in the exact same location hehe.

My MAF adapter is dodgey looking at best so I just pulled it out to seal it up better, found oil in the intake piping (fresh engine oil.)

I wonder if that's from the few days of driving before I plugged the TB pcv pipe, or is there another cause...

probably just pcv residue.... racers use catch cans because it will eventually fill up with oil, sludge. Same is true in the intake on a boosted engine, lower rpm tend to cause the emissions in crankcase more than high rpm called blowby. Re-route the pcv away from the intake altogether. If you don't run a catch can you might experience some fumey smells but it's livable.

Hey guys. I know it's been a million years since I've udpated this thread but I have been busy as of late and thought I'd share.

I ran a 7.703 not to long ago, 1/8 mile. Should (maybe) get me high 11's in the 1/4. Video is on youtube.

Haven't been able to run the 1/4 yet. Weather has not been good and the tracks have been closed. I might be able to run this Saturday if the weather holds, fingers crossed.

The list, sorry if I've mentioned some of this already:

Rebuilt the trans with Raybestos blue plates and an "upgraded" second gear sprag.

Had the tq converter re-stalled to about 3200rpm. Added a bigger (much) trans cooler.

Intercooler has been gone for awhile, using WM injection.

Put in some racing seats.

Deleted the ABS / Trac system.

Replaced both front and rear rotors. All were under spec after the last cutting.

Replaced front and rear pads with EBC "redstuff" pads.

Bought and installed Megan Racing poly motor and trans mounts.

Bought and installed a Cartech / Bell Engineering FMU. I think I've really been pushing the 315 injectors. Figured this will give me a much better safety margin without spending a ton of money to buy bigger injectors. I have it set for about a 2 to 1 gain with an "on set" pressure of about 60psi.

Bought and installing tomorrow, Technafit SS braided brake lines. My rubber hoses have about had it and upgrading to SS is actually cheaper than replacing with OEM, go figure.

Have just recently purchased a ton of stuff to rebuild / update my suspension. Front and rear sway bar links. Front and rear Prothane sway bar bushings. Front and rear Prothane control arm bushings. And, Megan Racing adjustable traction rods. I've been meaning to do the CA bushings for awhile now, been putting it off. Figured I'd go ahead and do everything while I was at it. I might still get some steering rack bushings.

I could use some advice on what to do with the adjustment on the traction arms. I sort of understand the theory on having them adjustable just not sure how to use them.

Purchased solid diff and subframe collars from here: http://www.gtfactory.jp/cms/page.php?17 (bottom of page). Not sure how these work yet but I have some slop in the rear end somewhere and I figured for $50 I can't go wrong.

I think thats about it. I'll update with some new 1/4 times if the track is open.

Khris

Sounds good mate!

I've been thinking of trying mine without the FMIC, but never got round to it. So it runs better without yeah? I'm hitting about 10psi through it at the moment and holding good ratio's (A/F) on lpg... Though I'd happily trade some power from the 5-6000rpm mark to pick up more boost down low, if that happens without the IC?
