Thread: HowTo: SR20VE Swap Into a B15

I'm looking to start this swap i bought the motor and now im looking into swapping it just needed answers to if this is a good walkthrough? and also i heard you can keep the b15 ecu? but my main concern was how can i swap it and keep transmission? what all would i need to have the 6speed lsd work with the sr20ve?

You need the p12 bellhousing for the tranny and an s15 flywheel from what I've heard.

here you go.

i am trying an adaport plate my friend gave me to run a b15 throttle body on ve itm. i will put it on tuesday and see if it allows u to run a iacv for b15ve swaps.

did canx2k give you mine?

yes he did, if this works i am sending him the ve iacv.

did it work for u...?


cheers

yep used it for a year or so. Add some extra rtv as there is a slight leak near the top.

This is provided by Zerosin. It includes the wiring for the IACV to work.

Sorry. Thought I posted this before.

The IACV on the B14 ECU is a pulse type, like an injector, and only needs one hot ECU pin. Disregard the others and use the one listed in the table below.

I also made an OBD1 to OBD2 to OBD2 32 bit conversion list.

I changed my handle to phixer over here.
