if so , well i have the possability to buy an h22 engine with transmition of a 99 prelude, i was just wonderig if I can upgrade and if so what other things should I think about ( things that i may need)thank you before hand

Legal depends on your location and your dmv laws. You can swap a h22 in there, just convert the engine to run obd1 and i recommend a obd1 p72 ecu. A b series is probably a better choice for suspension and steering issues. But yeah you can swap in a h22 engine and transmission. You can even use a B series transmission on it with the help of the adapter plate that they sell. Hope this helps

You will need a wiring harness and ECU for the h22. Possibley new axles as the h22 is a larger engine and the axle widths are different. The engine and tranny mounts are different and may need modified mounts or a mount kit purchased from an aftermarket supplier. In some cases, a new fuel pump will be needed. Then, depending on your states dmv requirements, you may need to have it smog certified by an auto shop that does certifications and tags the motor. You are going from a 1.6 to a 2.2 liter motor, so be careful of cooling differences, and a new radiator may be needed, but in the mods we have done, we have only had to replace two radiators. Are you sure you want to tackle this on your own? Good luck and I hope you aren't one of those many I see selling their "project" cars on Craigslist and Ebay.

possible, i not too sure aboutlegal yes, as long as you don't adjust the chassis, and the the dvla (UK) then You can do what you like, within the laws of motor vehicles, IE body wheels hot sticking out from body work etc.things to think about, up rate the braking system, most important, up rating wheel bearings, to take the extra power, and anything else, that the power will be transmitted though, IE drive shafts, prop shafts.up rate the cooling system too, and the suspension to cope with the extra weight of the enginethe only reason i said not to adjust then chassis, is because it you do u will have to put your car in for a sva test, and also is may mean that your car does not have enough points to retain its registration plate number, and mean your car would have to be a Q plate

Yes and yes...Unless your trying to spend a lot of money, its not the smartest idea. Nothing against the h22, there nasty if done right, the vtec is insane!....That enigne is heavy! It will bend the front end of your car over a period of time. That engine is built for a big car like a prelude and accord. The torque also, your probably not gonna like it because its too much torque for that car...but again if you spend the money and get it done right, it will be sick!! You should stick with b-series tho.

will the only way is to ask pros them selfs so go towww.jazzproparts.com ask to talk to an tech that what i did for my car and got the right engine for my 99 civic dx and swaped it for a 92-95 civic si DOHC V-TEC B16A motor and tranny and ecu love it to death
