ok i am building an all motor crx and i have a couple of questions i would like to ask before i get started.

1. i have a b18c1 block with a b16a head which ecu should i use i have both ecus also???

2. i am going to be using a ys1 racing tranny do i need anything for it to work right on the b18c block or should i be good to go with a bolt up???

3. because of the diffrent top and bottom of the motor which wiering harneses do i need i have to one from the b16 and i have the one from the b 18....would i need to put them toghter???

4. and finally what would be better the stock intake manafold or the skunk2 for the b16


thanks for any help anyone puts toward this.......

 

1. If you want to stay obd0 use the b16 ecu pr3 or pw0..
If you want to convert to 0bd1 use the p72 gsr ecu.
2.The cable ys1 bolts up fine..
3. Use your stock wire harness,,and if you have a dx you must convert to mpfi..
Also add 4 wires to your harness for vtec..
And if you plan on using the p72 ecu you must get an obd0-obd1 conversion
harness as well as an obd1 distributor for the b16a head.
4.Skunk2 intake manifolds are good..As well as the integra-R manifold and aebs manifold,and Edelbrock victor-x

 

^ what he said is perfect, also what is the "racing" ys1 tranny, or is it just a ys1 that you'll be using to race?

 

1. This is my next swap. I'll be using a hondata tuned p28.

3. stock harness

4. If you use a itr intake manifold you will not have fast idle on startup.

 

what i mean by racing is that it has prodrive spowl..thanks
