HKS3037S 56T Retune

Rob77... the exhaust housing you use on your TD06 be it 20g/25g will have a huge influence, just as it does on the HKS turbos. (or any for that matter)

Your using the 16cm exhaust housing which as you know is huge. Swap it for the 10cm like mine, or even 12cm like Trust recommend on the RB25 and the turbo will be alot more responsive.

And beg, borrow and steal and get a Trust manifold if you can, they are worth every cent as they make a measurable difference.

Steve and others are making great, responsive power with HKS turbos, just like some are with Trust turbos.

I think moral of the story should be dont sell your Trust turbo short. How responsive would a 3037 with a 1.01 exhaust housing be on a stock RB25

If I changed the exhaust housing to a smaller one I wouldnt make as much HP would I, on such low boost? I think I will change the manifold, but I'll go for the same design as gtst-vspec, a tubular one with steam pipe and then ceramic coated. This way I can keep it low mount and looking relatively stock to the untrained eye As for me saying its a lagmonster, I was poking fun, I dont think 4600rpm for full boost is that bad, it would be nicer quicker and I think its achievable if I do the ecu and the manifold... as I said give me about 5 weeks and the ecu should be in

[GTS-t VSPEC]

Rob, It will be interesting to see the effect that the ECU, then the manifold has on the lag. Will give us all some idea as the overall benefits:D

[Steve]

Rob, you may find if you put a smaller housing on, you will loose a few kw up top, but you will gain mid range and boost response.

[rob77]

Yeah, but trust exhaust housing are like $700-$800 and I'd have to have the housing modified to take my wastegate onto it I think I'd rather put that towards the manifold

[Steve]

manifold and a good tune - you reckon you have traction probs now:D

If you find a spare adj cam gear that would probably help too.
