And come to think i was pondering and pondering why my car was running sooooooooooooooo rich.

Heres the deal, im driving down the road and the wideband is reading 10.00 at idle and cruise speed, im thinking WTF! I then put 10$ in gas in and i get 15 miles down the road and its EMPTY!!!!!! i was like OMG this thing is a gas hog so what do i do, i check my fuel pressure....PERFECT. i check all my liquids and no leaks anywhere.... i cant think i cant think.....

I check my fuel filter, golden! i cant figure it out............so i check my spark plugs and BAM!!!!!!!!

check these out!


So i swapped them out with new ones, gapped em, and now it runs like a champ! Love it now, cant wait for tuning! dyno tune vid will be posted!!!



Now on to the new Brakes, the LS400 upgrade kit, rotors slotted/drilled in the mail....



Now the short shifter

Not that i know of....ive always used them. Im switching once it goes in the tuner. MY mechanic and tuner both said to switch them, hence the reason i dont romp on it....

what would u recommend?

WELL guys i need to downgrade

smaller faster spooling turbo is a must, im looking for a smaller turbo, 61mm maybe a 63mm ballbearing turbo, spooling at around 3000rpms not 4500 like mine now.....

what u think?

i still dont have my car running just yet. but it should be soon. Mines a GT35r twin scroll so spool should be quite quick.

I thought with this T67 Dual Ball Bearing it would sppol fast too, i was wrong haha, although the car isnt fully tuned yet so im going to wait and see.....

Even the 61 might be too big for what you are looking for...here is my boy's car with a 1j (264 cams) using a ball bearing Precision 6265 with a .81 back housing:

61 twin scroll should be good, the t67 dbb spools about 3500, full boost about 5 i either have to get used to it or go smaller. Im not sure, i think im going to wait until its tuned. Right now its untuned so we cant really judge yet ya know?

Your boys 1j put 600+ ? very nice, i was guessing mine like high 4's maybe 500's what u think?

That car actually made 648 @ 32psi on C16 when were done with it. The T67 on the 1J should be making 450+ @ 18psi

How about clutch, what clutch you guys use with the r154? Im looking to make that power if not more, ill be running about 20-24 psi, so i need a decent clutch

for now im going to just run a spec stage 4+ or a stage 5 to break in the motor, but ill be running a twin disk from ORC once drifting starts. the only way to do it imo.

nice ncie, i will look into that once tuning is done! ill prolly blow mine when tuning ahah

ANyway guys,
AN update on the turbo. I will be selling the turbo and running something new

ive done my research and wanted to do something different from what ive seen on here. Ive spoke with many supra owners and drifters, and i agreed with then...

63mm Twin Scroll is the only way to go

i agree with the twin plate orc. i have one in my car and its awesome
