What all do I need besides the hasport mounts, linkage and axles? does the A1 harness plug in on each side of strut towers or do I need a A1 harness all the way to the ecu? do I need a jumper harness? how do i wire for multi-point? What ecu do I need? Thanks for all the helP!

 

depends on what you're plans are. I'm assuming this is your first time trying anything like this so to make things simpler use the 90-91 integra ecu and stay obd0. no you don't need a jumper harness. no, the a1 harness does not match up. you need to convert both your engine harness and your chassis harness from dpfi to mpfi. there are plenty of write ups on here that give you the steps on how to do that. just search a little. this is a very common swap and there is loads of info out here if you just take a few minutes to look for it.

 

I just did a swap on my 91 si i didnt need much i just got the linkage cut and weld and also bought some motor mounts. Everything else got from a 91 acura integra everything fits just right you will run into the axles problem but what i did i got the whole front brake assembly and it runs good. pm if u have any problems.

 

pretty much everything you need to know

or maybe just buy a mpfi conversion harness off ebay iv been dealing with the guy that makes them for years

 

link???

 

monotech on eBay used to sell the dpfi to mpfi setup but i can't seem to find it anymore. he still has this

but i don't know if he will also do a dpfi to mpfi conversion. suppose it wouldn't hurt to send a message and ask.

 

ya all you have to do is email that guy and he will make u one up for 130 bucks or u can send him your dpfi harness and he will take of 30

 

thank you!
