Any tips, refrences, referrals, shops, sites, parts would be helpful hahaha

 

I can never get a straight answer with this question. Does an engine swap from a Base (h22a4) to a type s (h22a) require engine bay fabr.? Or can I just slip it in with the correct engine mounts?

 

<p>A true Type-S Prelude generally had ATTS, so although there is no engine bay fabrication, you would need a whole bunch of other stuff for it to work, since the ATTS system uses sensors all over the vehicle, a different ecu and control unit, etc.</p><p>If you just want to swap in a japanese spec H22 for a US spec, with a base tranny and no ATTS, then there should be no issues, just a straight swap, as long as you pay atention to any sensors and such in regards to the obd status of the car and engine.</p>

 

I do plan installing with the ATTS and swappin out the US spec for the JAP spec. Thanks for the info brotha!
