they are fine for racing.

im using a b16 trans on my GSR motor. and its goin to get raced. so i dont see why not

 

well my advice may not mean much on this matter since I am a new and all to the forums but not new to motor capabilities. I myself am running an 00 si with a built h22 turbo and a good friend of mine is running an 92 civic vx with h22 non turbo. Then we got one more 96 dx hatch running a b18c with turbo and nitrous and I'm not joking when I say this but he cant touch me. Now my car is currently set up at about 500 hp and his is not. But he is much lighter, so by that we should be somewhat more equal.With that said I definately say h22. the money you will spend WHICH IS NOT MUCH MORE IF YOU PLAN is by far worth it. There is not a new z06 or viper I cant hang with or beat trust me I have done it. So if your gonna swap why not swap the best and do it once the right way. Now it's all personal opinions so in the end your gonna do whats best any way. But there is nothing sweeter than pulling up to a light weight b18 with a turbo who thinks he has something and you smoke it. Trust me I had one and it was built to 450 hp and the guy I sold mine is still trying to out build me. Now I say mine is 500 hp but in reality it is a little more. Gotta make those insurance companies happy

 

H22 is about 80 lbs heavier than a GSR motor, so stop listening to people saying how heavy it is, its not THAT big of a difference. H22 is a good motor, GSR is a good motor. The H22 obviously has more TQ due to the output, BUT, theyre larger, and slightly harder to work on once theyre swapped into the civic, thats where I saw a problem. I was considering the H22 as well, but I decided to get a JDM GSR. I am happy with it, and I will turbo it once I get a new car, and this one becomes my toy. As for now, im happy with the GSR motor.....it is quick, and loves high rpms. I think you can do better with your price, as I got mine for $3,000 with tranny, axles, blah blah, and its got between 25-35000 miles on it. Assuming its got 30,000 on it, I paid an extra couple hundred bucks for half the mileage. Want my advice? Get the GSR. The B16's are the most OVERRATED honda engines out there.......Not that there is anything wrong with em, but when you compare a B16 to a D16Z6 or Y8, youre barely talking double digit WHP/WTQ gains........BARELY.
