need help, h22, h23, knocking, rebuild? - Honda Prelude Forum

Ok, i bought this 92 prelude si 2.3 dohc non vtech about a week ago. it was makeing very small pinging noises, but i changed the oil and it seemed to go away. i take it on the interstate yesterday and as i am coming off the off-ramp, the pinging turns to knocking. then somewhere down the street the knocking turns to three different noises.

A really fast clicking, like taping the fingernails of both hands in succesion on a table.

a pretty loud knocking that sounds like drumming two ladels on the side of a steel refrigerator.

and a metalic grinding squeaking noises that sounds like the noise your brakes make when they are going, exept three times as loud and all intermitent like.

So, i don't think this is good. The engine is a H22 a1. i am wondering if i should re-build the engine or if it is even worth it. Many post i have seen say that a rebuilt one ends up doing the same thing.

So if i go with a used one i can't buy a rebuilt used because it will be too much money. so i need to go with one from a person seller that i find off of here.

now do i go with the h23 engine again, wich seems to go pretty cheap, or do i go with the h22 engine? not only that but i need to find one.

Also, what does h22 mean? If the engine or heads that i find/ am looking at are h22, then does that automatically mean that it is a v-tech engine?

I have checked out the faqs for the swap. they seem pretty straight forward. But i just want to make sure that other than swapping the motor mount and a couple other things, is this going to work fine with my si?

I will need another computer right?

any other relevant information that i have forgotten to ask would be greatly appreciated.

Oh, yeah... i found lots of bumpers on ebay. but no actual metal bumper reinforcement. i need that if anyone has it.

As for the engine? i will have 350 this weekend, and i also have a 1985 yamaha fj1100 that i would be willing to trade to get my lude back on the road.

contact me if you can help.

OK... first of all, you say you bought an Si with an H23 engine, but then you stated that the engine is an H22A1. Which is it?

H22 means that it is an H-series engine, and that it is a 2.2 Liter displacement. All H22 engines have a VTEC (not VTECH) head on them. If you currently have an H23, and want to swap to an H22, then yes... you will need to switch to the H22 ECU.

All other info as far as what you need for the swap is contained in the FAQ's that can be found on this site.

i'd say go get it checked out before doing anything drastic like a swap...could be that you just have to adjust the valves...except for the squeeling...don't know what that would be except for some belt slipping maybe!
