Alright, mine is being shipped from hmotorsonline right now and I want to make sure I'm ready for it. I didn't buy the complete swap, just the motor, tranny and ECU. So I was going over what I need and I know that the dizzy will need to be modified, but I also wanted to know if I need a new header and new exhaust for it. I know to change the timing belt, water pump and rear main seal. I haven't heard about the clutch. I haven't gotten a definitive answer on whether or not the VTEC is pre-wired or not in the harness

So basically, what am I going to need to have ready once this big hunk of metal shows up at my doorstep?

 

A little more information is needed, like what year H22 you purchased, OBD I or OBD II. VTEC is prewired on 4th gens by the way. JDM motors usually come with around 30K-60K miles on them, so clutch is optional. If you are swapping from an "S" model prelude you will need to purchase a header since it is not included. Of course change the plugs and plug wires when it shows up along with a new distributer cap.

 

It's a 93 so it's OBD I. Any recommendations on what header and clutch to get? Should I put in a lightened flywheel as well? It also occurs to me that I will probably need a new intake. True?

 

My 94 s was NOT pre-wired for Vtec but no biggie. You'll need to wire the Iabs and also the knock sensor.

As for your distributor i bought a brand new usdm h22 external coil off Distributor king on ebay for around $165. That way i didnt have to use the jdm internal coil or convert it. If you go with the usdm external coil dizzy you can use your f22a coil. I tested my f22a coil before installing and it failed so i bought an msd blaster ss coil. You can use your f22a engine harness but some of the connectors need to be make longer. I bought and used a used h23 engine harness, then wired the aib,knock sensor and vtec wires in a seperate harness to the ecu. Search and you'll find which connectors to extend if you use your f22 engine harness.

 

Also use your f22a fuel rail but use the h22's injectors and fuel pressure regulator.

 

Ok, header-wise, where is a good place to buy an SMSP header? Also, what is a good exhaust that can handle some future horsepower? I was looking at Greddy but I want to throw the question out to the experts before I buy anything.
