My bad sorry guys...Turbo is GT3540 1.02 . Car is an r34gtt coupe.

I know....Rb25/30 boredom (not build ) question...but opinions will be cool Need to know some real Hp/Kw figures for my build...just your guesstimation possibly. Build 25neo head.+1mm over int/exh..rear head drain Stainless valves ..performance springs Tomei cams (poncam) Ati balancer ...prp collar..n1oil pump..forged gears..prp billet crank sprocket washers...billet backing plate to n1 pump..7L sump.. Stock crank acl bearings...87mm rb30 block..CP flat top pistons...Max peening H beam rods. Fuel cell...1000hp fuel supply..1400cc injectors. 6boost exh...45mm hypergate. Haltech elite2000....flex fuel. Real reason is so i know if my gearbox is going flying...

Hi guys....hoping to get some advice on my external gate while finishing off my build. Its an Rb2530 aiming @ 500kw range. Running a garrett Gt3540 /1.02...the external gate feeds straight off the turbine housing. Its a genuine Tial waste gate I think 35mm. It now has a 19.2psi spring loaded into it. My question is being only a 35mm gate will that play the game or is there a need to go to a bigger waste gate. Cheers for any advice. Jeff
