Hi guys.
Can somebody help me with which header from the following models will fit on a '91 CRX with a B20VTEC engine? It's JG headers with a 2.5" collector from IB I have to choose amoung:

94-97 Del Sol B16A VTEC
99-00 Civic Si Honda Civic
96-00 Civic EX Honda Civic
92-95 Civic LX, DX, EX, Si Honda Civic
97-01 Integra Type R
94-99 Integra GSR
94-01 Integra GS / LS / RS Non VTEC

 

You need to choose the header that will bolt up to your head. Assuming you have a b16, or gsr head. You just need the jg for the b-series. You will need to modify your front crossmember, or get an aftermarket one for it to clear.

 

i would say go with the GSR or ITR

 

Yes it's a B16A1 head I have on a B20B3 block. Where can I get an aftermarket crossmember for the CRX??
Could a JG B16A header for the Del Sol fit without modification as my CRX EE8 standard has a B16A1 engine in it?

 

I am using a GSR DC 4-2-1 w/o crossmember modification.

 

Then I assume you are using the GSR head right?
Would the ITR be the closest one to use and is it langer then a B16A1 header?
Which cat-back system are you using?

 

I have a b16 head and custom 2.5" exhaust. Not sure on the second question.

Check out http://www.jimfab.com Place Racing also makes one, and z10. IMO the jimfab one seems to be the best one for the money. I am pretty sure that all of the B-Series JG headers are the same, and will work with your setup. As I mentioned you can either get the new cross member or mod yours.

 

I heard from someone today that the ITR and B16A header have the same length. Since my CRX stock has the B16A1 engine in it then I don't see the problem with the crossmember. Could the problem be that the B20B block is larger then a B16A/B18C block or are they the same size?

 

The problem typically isn't with the length. It is usually how far it comes away from the head, and down. Check this thread. https://honda-tech.com/zerothread?id=270364
People usually do something along these lines to get their header to fit with the stock crossmember. The aftermarket ones are already open in the middle that allow them to fit. Hope that helps. Good Luck.
