flatrate Posted January 17, 2015 Share Posted January 17, 2015 (edited) 140 is fine.. wet pistons could be from something else.. not likely it needs a rebuild..FYI my car only does 95psi on a compression test.. as long as it's consistant your fine.. Are you sure the turbo isnt causing issue? the motor has been oil staved multiple times, so the turbo had to suffer as well. Wet pistons isn't a complete give away that something is wrong Edited January 18, 2015 by flatrate Quote Link to comment Share on other sites More sharing options...
aongch Posted January 18, 2015 Share Posted January 18, 2015 Just started reading this thread, thx for sharing the details. I'm just about ready to track mine next month, basically still stockish tune, stock turbos pushing 8.7 lbs boost, just under 260whp SAE. What advice or gotchas I should look for? Lots of discussion on oil pressure, I don't think I have an issue, but do wonder if some of the high speed tracks and high-g corners locally will cause any oil starvation. I have the RB25 pan, and someone recommended the McKinney baffled pan. Thanks for any suggestions. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted January 18, 2015 Author Share Posted January 18, 2015 I have the Mckinney pan but with external pickup. Its very nice quality except they didn't deck the flange after they welded it. I had like a 1/4 gap which probably would be fine with a lot of "the right stuff" but i had it milled down flat anyway. I would highly recommend it. if your tracking a lot i would look into an accusump and i would also put an alarm on your oil pressure gauge. Not a lot you can do without opening the motor up. also probably put an extra quart in at the track. Quote Link to comment Share on other sites More sharing options...
aongch Posted January 19, 2015 Share Posted January 19, 2015 ...also probably put an extra quart in at the track. Good point, didn't know the McKinney has these quality issues. I'll at least keep the oil topped up, but won't we run into foaming issues if overfilled? Quote Link to comment Share on other sites More sharing options...
helghast7 Posted January 19, 2015 Share Posted January 19, 2015 so the rings are letting stuff through on a fresh rebuild? something stinks.....something that makes you want to look up the definition of insanity. Quote Link to comment Share on other sites More sharing options...

ZT-R Posted January 20, 2015 Author Share Posted January 20, 2015 In the meantime i ordered some 335/35/17 slicks and some wider butter lips. I doubt it will fit but "imma try". Quote Link to comment Share on other sites More sharing options...
ZT-R Posted January 28, 2015 Author Share Posted January 28, 2015 Ahhhhh soo close.... i could raise the car about 1/2 inch and it would be fine but ehhh i guess ill try the 315s, just sucks to loose almost an inch of tire. Quote Link to comment Share on other sites More sharing options...

flatrate Posted February 7, 2015 Share Posted February 7, 2015 sweet, i bet it makes great power and holds together just fine. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted February 20, 2015 Author Share Posted February 20, 2015 Well the 335 looked mean as hell, but not quite practical on the street. so i went with 315. grrrrr..... Quote Link to comment Share on other sites More sharing options...
EF Ian Posted February 25, 2015 Share Posted February 25, 2015 315 is pretty wide, surely that enough rubber? If not you need some traction control or less power. I think 335 would look to wide when viewed from behind the car because S30 are quite small cars, it would look really over tyred. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted March 1, 2015 Author Share Posted March 1, 2015 People say damn that some tire on that thing when i had the 295's on there. ha she gets better traction but i have only driven it once on the new tires, weather has been crappy, either cold or raining. I need to get it to the dyno anyway. Quote Link to comment Share on other sites More sharing options...
