yea nah, different thickness. I don't know if you can get the metal multilayer the same 0.9 thickness can you?

genuine mines baffles, I just put some into mine.. seems to have fixed that problem good luck.

I just used the -4 lines on the feed, and has provided enough restriction thus far..

nice build. but why did you disable vct?

hi mate, that's one nice Z. I just went through that kinda pain in the not distant past... in regards to your oil filter block. if the stock rb30 threaded screw on fitting is there, you might want to measure the exact diameter on it, then check the block sleeve. My first motor failed because I left the 30 one on, which is a beez dick too small for the sleeve, and oil does not circulate properly, and caused the same failure that you have suffered. if you do have the rb30 one on the block, you need to get another one, or rb25 one which has the thicker sleeve.

use the stocker. its fine for power even higher than that. I used a rb26 oem one the first time, now im using a cometic metal multi layer. I have to say I liked the stocker better the difference in quench was noticable. it really depends on how much boost you plan to run and power figure.. for your goal.. it wont matter unless, as others have said, you want to save some $$$ if you need to pull the head off

Thanks for clearing that up. I reckon you can do it, just takes practice and time. Hopefully nextime i can break a mid-low 11 at least. cheers, D

ive got the same problem, mines baffles arrived and i will try them out without the other mods ( have the sump already modified to go) but i want to see if the mines baffles alone do the trick.

im a bit surprised actually I thought this car was a pretty serious piece of top dollar machinery already. any reason you decided on the precision?

free postage to anywhere in Australia. need to move them guys go.

the gtr will be tough to beat off the line, do you know what its trap speed was?

Gday ol mate!, definently! it would be fun, time to dust her off and come out and play

I went sub 13 (12.8) on my second run still warming up before the trouble started..

yes they will

no expense spared ay

still sittin on the bench wrapped up. seriously nothing wrong with this head.. it needs to be used.

buy my head, it will save u alot. i got a fully prepped 25 head sitting on my workbench, fully machined for a 30 bottom end. was gonna use it but i dont know if i can be assed to rebuild another motor. just get urself a new set of lifters and ur good to go. http://www.skylinesaustralia.com/forums/topic/422340-rb25det-head-modified/
