Because it is all about the bling haha No I agree though, factory low mount stuff is great if it performs well, which the Rb26 has wrapped up very well as is and Meh at SF lol

not impressed by them?

Nice thread name change (looks at Stevo) I'm not sure HKS would be able to pay for the rights these days, most of the big name Jap companies are struggling for cash. Would be good to seem do a twin high mount 2867 ext gate kit.... .....for JZ's lol

(with a 3.4L kit)

Ahh I didn't even think of the glazed bore issue, Wish I had a bore scope, would be nice to have a look inside

Yeah, it has me beat Will get a leak down test done asap, I really am hoping it is just the head causing the problems

lol @ "small exhaust pipe"

85psi? is that with a comp test? even with the 272 cams it sounds kinda low, is the cam timing spot on? What comp ration is it meant to have? With the oil pressure, does it make 90psi if you free rev it? or is it 65psi at say 5000 rpm off boost and 90psi on boost? If so than the rings aren't sealing.

All the cool kids have 5 high comp cylinders and 1 low comp one *grubles....damn Supra

The viscous clutch would have jammed up Find a 2nd hand good one

when was that 1993? lol I thought 16.5k was expensive when I got mine p.s reply to my PM dammit!

I had considered that, but it the smoke is too instant after starting cold, and I'll be f**ked if I am pulling 1J turbos off ever again! lol I will pull the cooler piping off tomorrow and have a squiz, but 20 years of crank case gasses being sucked into the intake pipe means it will be oily

Ahhhhh that would make sense then!!!

Yes I read that, was wondering if you had tried the Ross CAS, is a direct replacement one rather than the crank trigger setup Edit - See here

MRA and iRace = run what ya brung

Did you guys try the Ross replacement CAS at all? Mark has one on his 2530 due to the timing going all over the place, A proper crank trigger setup is always going to be better at big revs though

blue smoke yes on both hot and cold start, no miss-fires, even at WOT (warm)

Don't make me bring up 1J's Steve you going to (try and) low mount them?

So, easiest way would be pressurize the cylinder and listen in both the intake manifold and the tail pipe for the hissing? I would but my air compressor is at my old mans house 1100ks away lol Titan - yeah, only smokes if its idling for a while, if you blip the throttle after idling you get a big puff of blue oily smoke.

Hmm as Disco was getting at T3 internal gate 2867 for a response monster Rb25 at 30psi.....

Ye, I would love to see them match the 2530's but for half the price, IF Garrett do them properly and not have people shoehorning them into existing -5 comp housings Im sure they will.

Hokay, lend my your ears eyes, New car is down on compression on the number 5 jam pot, but I don't know why!?!?!?! it came up at 88psi when the rest were 150-160 The car has dodgy valve stem seals, so blows some smoke after idling for a while, but that is unrelated to the lack of compression. (or is it?) I initially thought the rings were shot, but it doesn't blow smoke under load and the motor is very quiet, has very minimal blow-by and feels quite strong and smooth, idles smoothly yadda yadda yadda. It is a dead stock 1JZ with a cat back, standard boost factory intercooler etc. Now to my theory, is it at all possible that the leaky stem seals have gummed up the back of a valve which is causing it not to close/seal properly? I'm sure it is possible, but I have never seen/heard of it in person. Now when my RB25 chewed up and spat out a ring, the smoke would increase with revs/load as well as showing obvious pulsing blow-by. I'm going to try and borrow another comp tester and squirt some oil in the bore to double check (I didn't have anything handy this morning) But like I said, no smoke under load, to me it doesnt make sense. So I hope you can help too a) put my mind at ease and b) save me from having to buy a new motor Cheers A

Spot on

The BA xr6 turbos used the same intake as the Na ones but ford removed the variable length butterflies The latest ones use a yb cosworth esque centre feed unit with short runners Forgot where I was going with this lol
