Is there a difference or are the specs of those fuel pumps the same?

 

I believe the gsr, itr and 99-00 si pumps are the same.

 

...94-97 delSol VTEC, 99-00 Civic Si, 94-01 GSR, and all ITR/CTRs have the same identical fuel pump.

what about 92-95 EG fuel pumps?

 

...not the same.

What about an 85 Ford Bronco pump?

92-95 EG vs ITR pump

how much stronger is the ITR bump vs the eg pump?

 

I don't have flow data, although RC Engineering should since they do pump testing all the time. They did the volume vs pressure test posted on Hondata's site. That one was from a Civic Si, which would be the 'big' Honda pump.

Let's just say it's enough of a difference that Honda felt to put the higher flowing pump on the other cars vs the standard EG pump. And that's just bone stock cars - you will find that on modded cars the EG pumps lean out because they can't keep up with flow. And for FI I wouldn't even consider the stock Civic pump.

Also, I forgot to mention that I am almost positive CRVs use the higher flowing pump. I have not verified it personally, but I know a lot of people that do B20 swaps into an EG has flow problems with the stock EG pump.

Personally though, if you have a Civic pump and were considering getting the higher flowing Honda pump, you may as well get a Walbro 190LPH pump for $70 which will be plenty of flow for just about anything short of wild FI setups.

EG2 and EG6 should be the same pump as well. along with any other car that came
with dohc vtec

 

Correct...when I said EG I meant SOHC.

B-series DOHC VTEC/DOHC non-VTEC pumps are the 'big ones'. So anything Honda stuffed those into got the big pump. EG2 (I already mentioned), EG6 etc.

Stephen, have you been able to verify a CRV for sure?
