I've just dropped a b20 into my 88 crx si.

I've got a few questions regarding the fuel system.
I'm using the 90-91 pr4 integra ls ECU.
I'm using the crx injectors, and distributor.

Is that okay or should I really be going for the teg Distributor and Injectors?
with the crx I have the resistor box, would i be able to use integra injectors using my crx resistor box?

Any info would be appreciated.

 

I would get the 90-91 LS injectors and distributor. Especially the distributor because I know it is being held on by 1 bolt! I did it before I bought the right one.

 

The injectors will work the same way with either the Teg or Crx injectors. You are going to need the injector resistor box with both.

 

But is it essential to use the integra injectors/resistor box/distributor?

I'm currently using the crx injectors/resistor box/distributor.

 

The resistor boxes are the same. I think that the injectors are the same too. I dont know about the Distr.

 

The distributor is identical too, except for the mounting arms. They function exactly the same.

 

Keep the injectors, they are all the same 235cc/min.
Keep the CRX injector resistor box
I don't know about fitment of the distributor on the B20 head, but as a rule of thumb, you should use the distributor and ECU out of the same engine.

What you need is a fuel pressure regulator like a B&M FPR.
Also get the fuel pressure gauge.

Now to make the whole thing complete, get a Halmeter.
it is the same as an air/fule gauge, but more acurate.
I have one and it has been super helpful to get the engine to run correctly. www.twminduction.com

 

Okay so the injectors and the resistor box are not a problem.

So the integra Distributor I need to get.

I already have the B&M fpr, and the little fp guage. at idle fp is at about 38-40


Now the main problem with my car is, it hesitates under acceleration. I haven't been able to find any sort of pattern. The air/fuel guage i have (autometer, not great but for now it does the job) doesn't show any change in air/fuel mixture when the hesitation happens.

My plugs were fine as well.

It doesn't seem to be the injectors, I've got spark...so now I'm kinda stumped.

I'm thinking it may be the TPS?

 

watsup maz!

didnt know u posted here

 

ha ha! what's poppin' G!

Yeah, I'm mostly a lurker here, but now i need some tech help, so here Iyam!

 

hey, how much does that halmeter cost? thanks

 

You may want to see what a guy named "SONIC" says about it. He and I just did the same swap with a 91 si. CRX injectors work fine. We have the 91 teg dist held on by one bolt. When we first drove it, it felt sluggish, this was fixed by checking the engine timing which I might suggest. We have it advanced to 18 deg when its running right you'll know. really ramps up around 2500, you can feel the cams come on. I have the CRX fuel pump and the 91 teg ecu and I consistently throw code 47(fuel preesure) so car is not even at optimum. Fun swap. Good luck!!
