I am doing a turbo swap on my 2nd gen rx7 and I am piecing together all the parts that i need, but my problem is that I am confused about the ecu that i need.
I have done my research, my 7 techy says this and all the boys in ottawa as well, that i need a n370 ecu for my turbo.
I bought a part from a guy on the forum and he sent me 374 instead of 370.
Is the 374 not for fd's ?
I am pretty sure that the 370 is the only one that is compatable
PLEASE LET ME KNOW!

thankx so much,
BRI

 

Nope that is for a turbo 89-92

Any N37X would work.

The N37X were all for 89-91 Turbos.

FD ECUs are N3AX

As I told you in your f/s thread where you're advertising the n374 as an FD ecu for $200 (lol), the n374 is an 89-91 turbo ecu. IT's just the japanese version of our n370, and is a direct plug and play for our 89-91 turbo cars. This will work properly in your conversion, if it is a working ecu. There is very little difference between them.

Any n37x part is 89-91 turbo. Any n35x part is 89-91 nonturbo. Any n3Ax part is a 93+.
