Just to let you know that the R34 gtt cooler is not a straiaght fit to r32 gtst. You will have to either modify the endtank on the GTT cooler so the outlet faces forwards OR modify the R32 pipework so it lines up.
I'm contemplating which to do myself at the moment. Not sure.
Modifying endtank - can get a welder to do it for about $50, get to keep my stock piping (so i can refit a stock cooler if i ever want easily). Can be done with my car still going (big plus when i have to get to the welder and back) But the end tank is designed to flow best to the current outlet position, so modifying the endtank could decrease flow capability slightly.
Modifying piping - unsure what exactly needs to be done. May involve cutting the car body. Never be able to refit stock cooler. If the stock piping cant be modified to fit directly, I'll be stuck. Upside - endtank doesnt have to be modified, dont have to go to welder.
So still not sure what to do...
Apparently the gtt cooler should be able to handle 200-220rwkw. More than I'll ever have, and I have a water spray kit ready to go on at the same time. I'm looking to go to a sliding performance RB25 highflow eventually but thats it, so the gtt cooler should be perfect.
