T28 gtir it is. Im not after extreme power as i still want to tune it a fair bit on e the wideband and get fueling and economy very smooth. Now i have confidence that i can run up to 11-12 PSI on a 100% dead stock engine. Im assuming with the lower displacement of the 1.6 the GTiR turbine should be sufficicent to hold reasonable boost right up until 8-9000rpm?

I can take pictures of the VET manifold for you guys if you would like? Im not sure anyone on here is using the factory one?

Snickers you mentioned that because of the shorter strok its going to be prone to less detonation, is this due to less cylinder pressure heat spikes and also due to the shorter stroke of it?


It will hold boost no issue, power will drop off a little before 8-9k though. It is still the turbo I would run however. A damn good powerband and I would expect AT least 300 wheel at 12-13 with your setup.

Do you guys think running the stock GTiR dump will restrict effort to get to 300whp?
Keep in mind i wil be extremely happy with 230HP at the wheels.

You will have no problem making 300 WHP with the factory GTIR dump tube.

I have seen GT28Rs make 360 WHP on the factory dump tube.

Porting the factory gti-r dump is also extremely easy and can't hurt. Smooth the edges baby LOL. Especially around the turbine outlet area.

I think Andreas mentioned the less detonation prone before i was going to. The SR16VE has the same piston area as a 2.0L and the same cooling "capacity" so it has better heat management which is the end all must have in turbocharged setups. The long rod, short stroke motor will be more critical to tuning because of the high piston dwell time, but i dont think you will get anywhere near detonation issues before getting to good power levels.

Plus the small turbos won't like the valve overlap that the big 16ve cams have, so you would want a little bit more separation between ports on the manifold. Who knows really, I havn't seen the VET manifold in person. It may do a good job at preventing reversion. But that small turbo will not be able to do the 16ve justice. Go at least a disco, with a free-flowing exhaust housing.

VET Manifold.

Looks like GTiR mani..

I don't think they're all that different. Next time I have mine off (in the next month hopefully) I'll compare the two side-by-side

The main difference is the placement of the turbo. The VET mani puts the turbo farther out. Andre fit a BB37 on his with some room.

so would the above factors matter if you were to sleeve the 1.6 to 1.8? with some 90mm pistons?

the reason i ask is because i have another block which is an SR16 block, SR16 8CW crank, and a stripped SR20VE head. im getting N1 cams for my N/A VE in my N15 shortly, so i will still have my SR16 cams, so i could build my SR16 back up but with lower CR pistons and some beefier rods, then stick a disco on it

does anyone do aftermarket SR16 rods?

sorry for the hijack
