reconmend an internal ex mani for 25/20

[R31 POWER]

Carl,

People also report a much nicer sound and more throttle response. Do you get this?

I love a car that leaps off the line and goes from 60-80-100 in a jump.

Dam thats a good result bigcarl :uh-huh:

T0nyGTSt I don't know if it was the bigger turbo or better cooler pipes and cooler(I did it all at once) but I noticed it revved quicker and has a meaty sound :uh-huh: but that could be the bigger exhaust housing?

I had to get both of my manifold faces faced coz it was a little out also.

It also mounted the turbo in the stock position sort of :freak: just the exhaust mounts had to be bent about 10mm towards the front coz it did'nt line up.

yea i saw the r31 gtsr manifold on a single turbo rb26 set up. was wondering how close the turbo would be to its original position. looked like you might be able to swing the compresser housing round and the dump would get close.

were could ya find one?

semi good news about the china mani's hey, they work but seems like ya end up spending extra on them patching them up. In the end it might be worth while getting a brand name. Im still not sure so ill wait and see the results, keep us posted guys!

and another question guy's what size turbos are you putting on these things. my turbo has a .6 ar compresser housing and to get it to fit onto the stock manifold i had to cut the heat sheld and angle grind the thrid runner to get it to fit. (as u can kind of see in my avtar)

If these china manifolds give more room with the design would be great.

with mine everything lined up perfect, im running hi flow stock turbo. we found that boost could also be turned up to 20psi with no pinging but one of my stock coil packs started to break down but once i rectify this will be making close to 240rwkws.

I fitted a HKS GT25235 and thats got a .64 I think?

interesting results....

although i always have been under the impression that exhaust runners that are tuned length jobs always outperform the standard .. suppose that goes without saying really.

as u really want the gas to arrive at the turbo at the same time .. helping spool up and reponsiveness. basically?? if these so called "tuned length" aussie designs were tuned length the results would show .. obviously they dont know what there doing then??

might give one of these china manifolds a go eventually. anyways. pity they dont have them for external gated setups.

.86 A/R it has.
