Hi. I have a 98 prelude type sh and my engine burns alot of oil. So I bought a jdm h22a euro r with lsd tranny and ecu. Can any of you guys tell me everything that i need to swap from usdm engine to the jdm to be able to pass smog in california

Have you tried searching?

You basically just need the USDM H22 oil pump and crank sensor (buy the oil pump from Honda, use your old sensor and lower timing cover).

You have to run the USDM ECU after that.

I'm sure there are lots of other things that you'd need to be CA legal. Try searching.

What about the intake manifold do i use the one that comes with the jdm or use the usdm. And will my lsd trans. Work ok with the usdm ecu

For ease of the swap while you are changing the timing belt re-use your h22a4: engine harness, idle air control valve, fuel rail, lower timing gear, balance shaft gear, oil pump with the crank sensor, and finally the distributor. This will have your euro-r full obd2 compliant. I did it this way for my swap, so I could just have everything plug n play and it was worth the time and the effort. Plus I have to pass smog so that was another huge influence of me doing it this way. Also order a Kaizenspeed manual timing belt tensioner it is a damn good part to have.

And one last thing you will need is to place an order from Rosko Racing. You will need to order: an IACV adapter plate to run the h22a4 two wire IACV, a euro-r EGR cover plate, fuel rail adapter kit for stock style fuel rails and ask him to make you custom spacers so you can use your euro-r injectors, and a Kaizenspeed tensioner.

And what about the tranny is my stock ecu going to run the LSD tranny or do I have to do any changes.

ECU's don't run LSD transmissions.
