get latermodel 4a-gze pistons from a JDM redtop 4a-gze... has a slightly lower compression ratio of i believe 8.0:1....
or you can get JE pistons as well.... those are generally good for about up to 30psi (according to some corolla owners on vvti).
you could also think about swapping in an entire 4a-gze.... it comes supercharged and has a stronger crank..... you can easily swap over to turbo or if you want, twin charge the motor
stock 7afe cams work well for mild turbo applications.
after that you need a cam re grind.

the "problem" as you so call it. with the 7AFE is a weak crankshaft, this is supposedly the first thing to get weak if you have a correct, well built race motor. which they also do not have readily available. basically the 2 toyota 4-cylinder motors that have the most readily available parts made for it are versions of the 3S motor, and the 4A motor.

the 300 horse 7age 20v that was posted up recently used a stock 7a crank. I don't know how long it lasted though...

are your tranny's actually holding up? last i heard, the c50/c52 transmissions were only good for up to around 200hp..... i'm guessing a 4a-gze e51 (from japan) transmission could probably hold more....

All that money spent on 7AFE and hybrid applications and a Civic with an H22 swap will still eat it. People gotta balance things out before starting to throw money and time away.

how has he thrown money out? he gets parts from pull-a-part junkyards and does all the work himself...... the only thing that he won't use on the hybrid is the 7a-fe engine specific parts.... he was originally going to turbo it though.... i think that changed when he decided to turbo the te27....
also, a civic with an H22 won't outrun a corolla through corners.... it's way too front heavy and will want to swap ends easily... along with that, the H22a's are fairly expensive and the swap isn't easy per say.....
pretty much any honda swap is plug and play. its like messing around with legos.
still 16-15s after that many hours working on a motor? seems kinda pointless IMO even if its not a strip car or anything... thats still pretty slow.

weve gotten way offtopic. all im trying to say is even though the setup is kool and was cheap, the gains are less than impressive. i feel if it is a car setup for autoxing, that money could have been better spent in the suspension and tires. all that stuff most likely would put him into a SM class, where cars are much more modified.

i'll just put it as his 7a-fe pulls just like a 4a-ge smallport..... if you can keep it n/a and do that, it's well worth it..... and i'm defending him a bit because he's a friend of mine and he will be helping me out more than i could pay him back for

The biggest problem I see is that the 7a manifolds will not work on the 4a head. The intake could be a problem. Getting sensors to switch over could be tricky. You'd almost certainly have to use the 4a ecu (or a standalone) to realize any power gain. The 4a head flows better but its not going to make a lot more power until you get the air moving faster (i.e. higher rpm). The stock 7a rev limiter on my car is at 6750, not 6200 or something as many of you have suggested. I suggest that you don't pay too much attention to the tach needle as its not very accurate. I've heard several people suggest that the stock 7a bottom end will live just fine at 7500rpm. This suggests to me that a properly built and balanced bottom end (but no really trick parts) could live to 8k. At that point you really have the potential to make some power with this conversion.

with using a smallport head, you will have to do one of the following (in preperations of us doing the motor swap in my car we came across this issue but got lucky, we think)
you will have to use high ohm injectors from a smallport or use the stock high ohm injectors if you plan on using the 7a-fe ecu..... luckily we're finding that the injectors on my smallport (we believe are the 250CC) are high ohm and we won't have to worry about that for now...
please clear this up for me: is the small port the blue top or the red top? Or is it just a edition of one of them? I also asked what TVIS was a while back and never saw the response.
