Hey guys. I had a question for ya. I recently came into possession of a built GSR (B18C1). It was built to be boosted with Manley turbo tuff rods, 81.5 CP Carillo 9:1 compression ratio pistons, micro polished and knife edged stock gsr crank, full Supertech valve train besides valves, stock valves with 5 angle grind, stock GSR cams, Skunk2 cam gears, and pro series intake manifold, and i added 320cc Denso injectors, stock fuel rail, stock B16 throttle body to finish up the last couple parts the motor needed. And i will be using a ACT heavy duty clutch set with ACT lightweight flywheel, and a EM1 B16 trans. My question for you guys is that i want to run the motor N/A and i know thats not a huge issue, but how much power do you guys think this setup will make? i know it will be very reliable and it should be able to rev up 9000rpm or higher and be somewhat quick cause of the B16 trans. And for anyone that is going to ask, the car will be tuned on Hondata s300 with 91 octane by my local tuner. but do you guys think it will make 200HP on a good tune? thats my goal at least. i would upgrade the pistons to nippon racing full floating p30 high compression pistons but the motor literally has less than a minute run time.

 

So, you have a fully built GSR engine that is essentially a stock GSR with a full point LESS compression and an intake manifold... and you expect to make MORE POWER than a stock GSR ??? Not gonna happen. You will likely be fortunate to break the 150 WHP mark... a far cry from your 200 WHP goal. Your valvetrain may very well be able to handle a 9000 rpm redline, your low compression and moderate camshaft will likely stop making power at 7000 rpm, so there will be absolutely no reason to rev the engine that high.

200 WHP will require higher compression (10.5:1 to 11.5:1), aftermarket camshafts of moderate size (older "Stage 2" from Crower, BC or Skunk2 Tuner series) and a quality header with properly sized exhaust.

Oh, and this is totally in the wrong forum... there is nothing about transmissions here. I suggest you contact a Moderator and ask them to move it... maybe to the '92-00 Civic section.
