Drax240z Posted August 4, 2003 Share Posted August 4, 2003 Just got 6 supra turbo 440cc/min injectors sweet. Has anyone used these injectors before on an L series intake, and can tell me if the injector ports have to be redrilled to accept the O-ring? Any tips from someone that has done it would be appreciated. Planning on a new fuel rail, and a much nicer looking intake to swap on at the same time. (I'm going to get a 2nd intake and clean it up much better than the current one before swapping) Getting there. 3" exhaust is high on the list of upcoming mods, as is the 3.54 R200 I have in the garage.

Cody 82 ZXT Posted August 4, 2003 Share Posted August 4, 2003 I'm running the bosch 440cc injectors that come with the JWT setup. They bolt in no proublem but, getting the connector to fit right is alittle tough. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 5, 2003 Share Posted August 5, 2003 I've got a set of 6 2nd gen RX-7 injectors ready to test and install if the duty cycle on the SVO units gets too high... Gotta rebuild the test bench, find out how much those babies really flow. Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted August 5, 2003 Share Posted August 5, 2003 I am running the supra injectors on my Z right now. they fit in the manifold just fine, use the OE Oring's on the manifold side. I can send you some pics of the fuel rail, its a little wierd but gets the job done well. I couldnt locate the stock supra plugs, so my injectors are very "poorly" wired right now later ~Kenny Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 5, 2003 Author Share Posted August 5, 2003 Yeha Kenny, I'd like to see some pictures of your setup. For those of you running a straight fuel rail, what have you done about pressure regulator relocation? Any ideas to incorporate it so that it doesn't look like an afterthought? I don't have any great desire to buy any other type of FPR, as the nissan one will do the job for me, so looking for other options for mounting to clean up the engine bay a bit. Went to a 700 car, car show yesterday, and got waay too many ideas. Quote Link to comment Share on other sites More sharing options...

The firewall is not a safe place for it, and that's also the reason I went with steel braided line from the rear of the rail to the regulator, as it passes behind the engine on the firewall. I think you'll have trouble making the stock regulator not look like an afterthought with a straight fuel rail, just MO. Quote Link to comment Share on other sites More sharing options...
240hoke Posted August 5, 2003 Share Posted August 5, 2003 well i am using the stock FPR with a straight rail and i think it turned out fine. Im running the fuel into the back of the fuel rail(firewall) then I have the regulator mounted on the front of the engine on a stud coming out of hte head (which i think was used to mount hte old fuel rail). All it took was a little modifing of the mounting bracket. -Austin HoKe Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted August 5, 2003 Share Posted August 5, 2003 I did mine like Hoke, except I was using a Bosch FPR. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted August 5, 2003 Share Posted August 5, 2003 Heres what I've done with mine. Not sure why it would be unsafe as Sleeper suggested but, who knows? Anyway. This seems to be a convient location as it's out of the way and doesn't get as much heat soak as some other areas might. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 5, 2003 Author Share Posted August 5, 2003 Ah Scottie comes through again. To me that looks like the cleanest mounting position. Sweetness. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 5, 2003 Share Posted August 5, 2003 Drag racing sanctioning bodies do not allow firewall mounting of fuel systems for (I believe) one reason -- clutch and tranny explosions tend to take out components on the firewall, for rear wheel drive. I think in general it is a bad idea to run fuel lines in harm's way, such as behind or in front of an engine where they can get damaged in a crash. Datsun had a reason for running the fuel lines in steel across the engine. That's why I turned to the reinforced, braided lines to run mine, despite the fact I'm a cheapskate.

Scottie-GNZ Posted August 5, 2003 Share Posted August 5, 2003 Sleeper is right about mounting fuel components on the firewall. Look at my pic and you see a big Fram fuel filter mounted on the firewall. Despite braided hoses, I had to relocate it as per the track (NHRA) rules.
