Just got my R34 Gtt basic dyno tuned, playing around with the boost. Got the following mods with no Nistune or aftermarket ECU yet...

Hybrid FMIntercooler

3' turboback exhaust with standard CAT

HKS electronic Boost Controller

Yellow jacket coils

Some good after market POD i cant remember lol

Everything else relatively stock...

would have been running close to normal boost (dont think it was tuned before), obviously slightly higher because of the aftermarket parts...

1st stock run = 204kw or around there... and 214kw after boost increased to 12psi :s not toooo bad

Do you think the standard ECU and maybe CAT are holding it back from more power?

I know the ECU because of the drop in midrange power :|... thats the next upgrade... anyone else have any tips?

WIll be getting the sheets in the mail

As above, with those mods and no more than 12psi, i wouldn't be expecting higher figures than what you have already, stock turbo isn't going to live too long on more boost, so that's probably going to be your first restriction in the chase for more power.

    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
    • Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
