I pulled the plugs after some spirited driving and the car appears to be running pretty lean with the factory Si fuel pump. (light grey electrode)

Anyone know what a factory type R fuel pump puts out? I was just going to buy a type R fuel pump but the add says it works on 92+ vehicles.

97 spec JDM ITR swap with 98+spec header,bolt-ons,exhaust.

 

if it a intank pump you can use it

 

grab a walbro.

 

What I dont want to do is go with too big of a fuel pump that will raise the fuel pressure and make it run rich. I figured since the CRX has a return line on the fuel system you could run whatever fuel pump and just bypass the excess gas but I have read several threads to the contrary.

If I can run the factory type R intank pump that would be sweet.

 

you can run it and the fuel pressure thats what the fpr is for

 

your stock pump if fine. guys run boosted with the stock pump

 

yup. stock pumps are pretty good for while

 

Thanks for the replies guys. I am going to run a wideband just to make sure. I'll post up the results in a couple weeks.

 

I ran a stock D pump in my H22 hatch with no problems.

 

A little update, my car was indeed running a little lean at the top of 3rd and real lean at the top of 4th. I should have just changed out the ancient weak fuel pump starting out.

I installed a Type R pump and it was easy money.

BTW: If anyone finds this post with the search engine someday.

You cant access the fuel pump from in the car like many suggest on a 1988 CRX.

The pump is in the rear drivers side of the fuel tank and you have to drop the tank to change it.

 

wouldnt you need a different pump for an h22?
