Just wanted to know if anyone here has swapped a B20A3 in the 3rd gen S with the B20A5 from the Si. I am planning to do this swap very soon but would like some pointers from someone with any experience. Of course this will be the Carb to EFI swap, and I am currently rebuilding the B20A5. Some of the items I have for the swap are: A5 wire harness, ECU, Walbro 255ltr/hr Elect fuel pump, and of course the long block with all new gaskets, rings, and the rest of all that good rebuild stuff. I also am aware that I need to run another return fuel line and will also need the mounting bracket for the fuel pump, those are on the way. If there is anyone with info on this, please share. Any help is greatly appreciated.

 

just bringin it back to the top, I never seem to get any response to this subject. ANYBODY?????

 

Whoa!! Where did you get the 255 walboro??????? Im looking for one now..

 

the reason no-one has responded is because you have the dreaded B20A...

that aside, i have installed a b16A into my prelude and had to go from carbie to EFI so i know where you are going...

I needed to run hte return line, install a surge tank, high pressure pump (Bosch), modify the pump bracket and several other things.

you have not really asked any specific question so i will stop there.

well thanks for the replys fellas, I know that people dred the B20A motors but i'm gonna try what i can with what i've got. I have done some port work to the head and polished it up, all that's left is for the gaskets to go on, and for me to get this fuel thing straight. Tinkerbell, do you have an AIM s/n, or an e-mail addy, I know it's prolly listed but i'm typing right now and feel lazy , I can't think of anything else for right now, but I would like to be able to get in touch with you for any questions that might come up later or during the swap. Thanks again
Peace
