carb to injection with Prelude Si parts

[SCAM1109]

Will it work? 88-91 Prelude is 2.0, Accord is 2.0, possible. Prelude has B20A 2.0, and Accord has A20A 2.0. If so, what other parts would I need to make this conversion work flawlessly?
So far I have: 88-91 Prelude Si intake manifold
88-91 Prelude Si fuel injection ECU
88-91 Prelude Si ECU wire harness
Modified 250cc injectors (or whatevers suitable)
sensors???

uh I don't think that works. You'll need a SOHC EFI ECU I believe.

And you should have gotten a B16 or B18C5 intake manifold and fuel rail.

it won't work. you will spend more money using prelude EFI stuff, then if you would use b16 manifold.

If you were trying to use a 85-87 lude it might work cause they are the same engine.

If you use the A20 intake manifold/throttle body, you just might be able to get away with using the B20's ECU. I've been hammering around with that idea for a couple of days. You'll need to find an 88-89 exhaust manifold or headers b/c the 3g Lude's ECU wants two O2 sensors.

Beyond that you'll need the EFI fuel pump and lines, etc. Everything that's hooked to the intake manifold as well... the EGR valve and other various sensors.

You might be able to get that to work... you'd also get the benefit of a PK2 ECU which gives you more flexability for chipping. Not as much as say, Sean's setup, but you're sitting more on the affordability side of that scale.

I have the JDM ROM dump of that ECU if ya want it.

Well if you need to the lude exhaust just get some accord DC or pacssetter exhaust they both have two 02 sensors, but still the custom work you have to do to the intake is not worth it. It would be easy to just get another 3G accord.

So I should use b16 EFI parts???

For the easiest setup, use A20/BT parts.

only the intake manifold and even that requires some work. everything you want from an accord.

I have all the parts you should need if you want b/c I have my 91 Prelude Si for a parts car now to support my Accord habit ... But I just took out the FI stuff, the TB, fuel rail, intake manifold and a lot more too. Let me know if you need anything. I'm selling all that stuff for $90 + shipping.
