hahaha....yes, there is a USDM f series motor called the f22a1 (i think thats the right number at the end) that is the honda prelude S model engine which is also the same motor that comes in the 94-97 accord ex but it has vtec.... both are SOHC. in japan there is a motor that came in the 4th gen preldues that is called the f22b.... stock rating of 160hp and is almost identical to the h23a1. in fact the f22b has a history of running better times in the quarter mile then the h23 in stock forms. so no disrespect.... you should do more research. i have seen your car at a h/a meet and its very nice and i have talked to you before too....your a cool guy from what i know... and i have known you have a jdm h22a. on average though. most h22 vtecs in honda prelude 4th gens can run 15 flat to a 15.1 with i-h-e. even with automatic. i know plenty of kids all over the us that have time slips and everything along with pictures and videos. so if you need proof... i can get it for you. also ..... the normal whp for a h22a in stock form is around 160-170 from the sheets i have seen. i have also takin 2 5.0's... all both of them had from what i know is pipes but i still took them. hell... AJ187 with the crx with zc swap and bolt ons has taken 3 or so 5.0's and i took him by about 3 cars. and you can ask him. we ran about 4 or 5 times. all the guy in the cougar said was that he had bolt ons, ecu shit, tranny shit.... and a new lsd... i asked for specifics and he said i-h-e and stuff like that. but he also said he takes it up to the track every couple of weeks and runs it. the track is right up the street from me in orlando. and no, stang2841.... that is not a challenge either. i wouldnt mind racing but just for fun. lol. and the jdm h22 trannys in lsd are sought after even for the us h22a1's. its supposed to be the best automatic tranny made for the h22's.
