Re: H23a VTEC??

The price on that engine looks pretty good. But I am, as many other are, more comfortable with the JDM H22A swap. I would assess that you could potentially get better help if you did the H22A vs H23 VTEC that not many here would have direct experience with. It also depends if you want higher rev's or more low end torque.

Re: H23a VTEC??

My experience : I like the H23A more than the H22A. It definitely has a more toreque'y feeling on the low end which is supported by dyno results.

However, for the money, its gonna be cheaper to buy the more expensive h22A engine.

Reason being is that more than a marginal amount of work has to be done to adapt the car to the H23A. If you put the H22A in you can use the same ECU's, harness, etc. It is NOT a straight "drop in". Extra work has to be done for it.

This is especially true if you want to keep OBD2, chipping and going OBD1 is the cheaper route but beware, you may not pass emissions like I did if you live in a state that has stringent emissions protocols.

You might also want to check my post history. I've got a post on what all was needed for my swap and the emissions problem.

Depends where you live. My engine runs fantastic, but it still wasnt in spec, it being a euro engine. And shops up here wont give you a waiver since its an imported engine.

I've heard Washington is pretty strict, but then, that's hearsay.

Re: H23a VTEC??

The H23A is pretty much a drop in. You just have to either A) swap the oil pump and crank sensor or B) rewire for the H23A's distributor. It definitely pulls harder than my H22A did, especially in the lower RPM's. I recommend the engine, I paid $700 for mine and just freshened it up a little before I dropped it in. No problems in the 1.5 years I've had it in my 99.

Jeez you did it that simply? Learn somethin every day. Did you just use the same ECU as your H22A?

Re: H23a VTEC??

I can also vouch for the h23. Put one in my '01 a few months ago and I LOVE it. The torque is night and day compared to the h22, which is perfect for daily driving. Most people swap oil pumps to run the crank sensor, but I kept the original pump and just rewired my harness. PM me if you need help with that.

Re: H23a VTEC??

I am still using the stock h22a4 auto ecu that came in my car. Though I am debating an obd1 conversion just to be able to get everything working at optimal levels.
