  1. Yes. But the rolls are narrower, the fins are closer packed. It did not flow or perform as well as the cheap replacement, That was later replaced with a PWR cooler.
  2. About factory GTR intercoolers. My 1998 S3 R33 GTR with factory cooler, boost curve: Cooler changed to Takashi (not the best) 600x300x100mm with no other changes: Compare the two coolers: inside new cooler: inside stock cooler: I'm unsure of other GTR models, at least factory R33 S3 GTR front mount cooler is quite restrictive.
  3. R34 GTT Rb25det NEO Stock engine HyperGear ATR45SS Turbocharger ID 1000cc injectors Walbro 525L fuel pump Power FC + Z32 AFM Greedy Profect B EBC 600x300x81mm PWR Cooler kit 3inches turbo back exhaust 4inches intake pipe with Pod Split fire coil packs Turbosmart 45mm external gate welded on exhaust manifold. Car made 400rwkws @ 24psi, E85 fuel. Hitting 20psi by 4000RPM.
  4. ATR45SS Rb25det NEO round 2 with fuel pump issue sorted. Now pulling 400rwkws at 24psi on E85 fuel. Car mods are listed in video below: https://www.youtube.com/watch?v=hrVjIMxIFrA
  5. The biggest you can fit using air box would be 3 inches, I would prefer a short 4 inches metal pipe in between. that provides better throttle response over 3 or 2.5 inches. Actuators, something 14psi or one of our high pressure actuators will do fine.
  6. Nice result. The pressure drop would mainly be restriction on cold side. A FMIC with a better cooler, 4 inches metal intake and free flow exhaust should see another 10~15kws gain.
  7. further update with prototype ATR45ss turbocharger. Car made 364rwkws before running out fuel.
  8. The 53.8 in 47 ex would be the best turbine wheel for SR20det, run that in T2 .61 turbine housing externally gated.
  9. One more result to share: Rb25det NEO Stock engine HyperGear high flowed Turbocharger ID 1000cc injectors Walbro 460L fuel pump Power FC + Z32 AFM Greedy Profect B EBC 600x300x81mm PWR Cooler kit 3inches turbo back exhaust 4inches intake pipe with Pod Split fire coil packs Turbosmart 45mm external gate welded on exhaust manifold. At higher boost level we've reached 340rwkws before experiencing ignition break down. https://www.youtube.com/watch?v=Mgz8Wzyc6X0&t=6s

  11. More video to share. This is an R33 GTST powered by one of our ATR45SS1 turbochargers at Hitec drift last weekend. Car's currently making 401rwkws on E85.
  12. The SL205 makes the same power as a 25G with better response. If your current turbo is not blown I can have that modified to the same specifications as the 20.5 with a 10cm with turbine housing supplied for less then half the cost of a new turbo.
  13. It acts as a normal anti surge slot. There is a lose in compressor efficiency. I did a comparison years ago result is in this thread. There was a lose of 300RPM and 11kws with that particular turbo used.
