engines
 

i want to change my stock engine, if anyone knows whish is the newest engine that i can put on my 90 civic hatchback i will appreciated

U can put any obd0 motor in for the simplest install. So a 1st gen b16a(158hp) or a b18a1(135hp) for a b-series, or d16a6(if u dont have an si, 108hp), d15b5/6(130hp), or sohc/dohc zc(120-130hp) for the d-series. There might be a few motors that i'm forgetting, but those motors should swap in the easiest. If u go with a newer engine, you'll have to run obd1/2 to get it to work, which can be a pain to do, and expensive if u don't know how!
Do lots of research before u decide. I went with a 1st b16 for my 89 crx si. It doesn't have a lot of torque, but the b18a i was looking at offered only 130hp and 121ft/lb torque, so it's not a big difference in torque(111ft/lb-b16), but a big loss in hp from the b16. I don't wanna run obd1 either, so that's partially why I didn't buy the b18. Plus, all the wiring the b16 requires is four wires that go into the ecu, that's it!
Hope this helps ya, good luck!

the newest motor would be the k20a2. you have to know what u are doing and have the right kind of money .

The K20 is abouta sick ass engien. But it is going to cost alot more to do what you want to it. And you will have to change out alot more stuff on your car. ie: gauges, harnesses, and alot mroe stuff. BUt if you have the money, it is well worth it. You will rock out with that engine.

do you know if i can put a V6 in my car, or thats just a wrong idea
