HEy do u guys think this would be a good mix ? GSR WITH B20 BOTTUM
if im thinking of a swap in about 3 weeks would this be good ?
but im not every sure i was thinking of just dropping a gsr and adding turbo in the future but since i have experienced turbo before its ALOT of headaches
or a gsr with ITR tranny and then super charging that .

oh yea, got to love that torque. Careful with the red line, don't go past stock setup of CRV. As for the head, The Skunk2 stage 2 cams will run well up to about 8500 with a stock GSR head. They don't tend to be a "lot" of cam for two liter combinations. As far as manifolds go, take your pick...AEBS, ITR, Skunk2....they're all about the same, with a very slight edge going to the AEBS..it's also the cheapest. ITR trany will be a bit much, GSR would be ideal with LSD to utilize all that torque.

if you can afford to go for an ITR head, i'd suggest that since you seem to be staying n/a. the reason against the GSR head is that the intake manifold kinda sucks for n/a if you plan on building it further (the IAB's). also, the intake manifold bolt pattern is different than the B16 and ITR head...mite suck if you buy a Skunk2 IM and decide to sell it later, and also the IM sits lower and may become a problem when you're looking for an intake (esp. CAI's).

anyways, just my 2 bits! good luck with your build up dood

wouldn't hotter cams be a bad idea if hes staying at CRV redline?

bigger cams with stock pistons can become an issue b/c the valve reliefs in the b20 pistons are tiny (especially compared to the b16/GSR/ITR pistons), this is b/c b20's use smaller valves.
So if you use higher lift cams that stay open longer (more duration) ur increasing your chances of the pistons hitting the valves, especially if you're gunna rev it to 8000rpms or higher.
You can cut deeper valve reliefs into the b20 pistons, but then A) it will drop the compression ratio and B) you really should balance the rotating assembly after removing material from the pistons (which means time to tear the engine apart and get new rings/bearings).

zeeman is right about the stock pistons hitting the valves. I'm assuming that you where gonna change them... You have to have strong bottom end for this to work a be a successful project. I would spend more on that than the head. even minor DIY polish on the head gives great results. Skunk2 cams are great even for a stock B20. Bottom end gains are noticable.
