No, fd injectors are side feed, while our injectors are top feed.

Also you need something to tune the injectors to take away fuel.

If you want bigger injectors to run your 6 port turbo, run the fb injectors.

There 680cc, and peak and hold. (Low imp)

What are you using to control the fuel? Also upgrade fuel pump, if you haven't yet.

Ebay fd's secondary's

http://cgi.ebay.com/ebaymotors/FD-Ma...Q5fAccessories

^^ Side feed.


I already looked into fd injectors for my 6 port turbo.

http://cgi.ebay.com/ebaymotors/93-95...Q5fAccessories

^^ Injector itself.

http://cgi.ebay.com/ebaymotors/550cc...Q5fAccessories

Fuel rail from fd with both injectors. So I stand by side feed.

I just searched to prove I am not crazy, and it appears that I am crazy. Correct, FD secondary injectors are side feed. I deleted my post which contains wrong information.

I must have been thinking of the 13B-RE.

It's already been corrected, but here's a page out of the '93 FSM:


Scanning through some of the posts in the 3rd gen forum, it seems there are some aftermarket rails for top feed injectors available for them too.

The 13B-RE is the one with the weird injector combo. I think one set is top feed and the other set is side feed?

It's most likely that's where the confusion is.
