Just ordered a ct26 60 trim upgrade from driftmotion. I figured that I was going to get it anyway so might as well get a black Friday discount. Didn't see any options for exhaust clipping, is that something I should look into. Next up is getting injectors. 550cc or 660cc. I have a Greddy Emanage ultimate piggy back to manage everything.

Starting to realize with this build that patience is important. After I brought the ct26 60trim upgrade I came across a Borg warner s366 for the same price. Its a t4 but hell I'm going that route eventually. Sale lasts until Monday night so still get it.

they were from another member some time ago. was told they were never used. Not sure of the brand. Im not not sure what id sell them for prolly not much. I do need to get more so we may be able to work something out. I know I was thinking of upgradeing to the rc 750 at a minimum.

Need some input on piston ring gaps. I have je pistons 83.5mm or 0.020 over and was wondering what a good ring gap should be for 400 - 500 HP range. I plan on boosting around 15 psi and maybe 18 psi for track days. I never measured them when installing and now its been bugging me ever since. I plan on pulling them out to measure/gap, but not sure on the correct size. I also lost the paperwork that came with the rings so no info on JE's recommendations. I need some experienced advise please...

Thanks Rollus. After getting some experienced advise and understanding the end gap formula, it was recommended to gap the top ring to .016" and bottom ring to .019". Where I'm at on the build all I have to pull is the exhaust manifold and head. The oil pan wasn't sealed yet so no cleaning required there. Gonna leave the intake mani on for an extra handle when pulling the head. Can I reuse the head gasket after its been torqued down? ARP head studs to 90 lbs. Its a titan 1.4 mm gasket. What do you think?

Damn this update is past due... I have been working on the Sup though. Got so much done since the last post I had to read my own thread to see where I left off shittt. Well I pulled the engine back apart and gapped the rings to .016" top ring and .019" bottom ring (they were at .0015" before cutting em). It was actually a good thing I pulled everything apart because we got to clean up the cylinder walls and every other exposed surface of metal again. This time it looked even better than before cleanwise.

The turbo came a week before Christmas. My holiday couldn't have been better. Stayed with the upgraded ct26 60 trim billet wheel. Tried uploading pics but keeps failing.
