has anyone besides me bought one of these? says it fits 2005-2007 lsj engines.



reason i ask is i picked one up for my engine swap project (944 porsche with 2.2l l61 ecotec) as i figured it would be easier and cleaner to just plumb AN fuel lines than adapt a stock rail. i have a stock lsj fuel rail mocked up on the 2.2l head, fits without an issue. this obx rail, i just cant seem to make it fit correctly. if i try to bolt the rail up using the included brackets themselves it wont work, the fitting closest the front of the engine hits the water outlet area of the head, and the rail hits the head where the valve cover bolts to. i tried using the spacers from the stock lsj rail, it fixes the clearance issues, however now the injectors are too short (im using id 850s, 60mm long, as spec'd for the lsj by injector dynamics). i found some short injector spacers kicking around the shop and they are too tall, at least without adding a washer under the spacers on the rail.

anyone actually installed one of these things? i just cant seem to figure it out.

Everything from them has fitment issues and requires modification, no joke.

i realize obx is a crappy brand, and in all fairness it was a cheap fuel rail. aside from that, its the only aftermarket fuel rail i can find for the ecotec.

I think you'll get much better fittment and luck using the stock LSJ rail. Its very easy to adapt an lines to it.

I've done return on it in an and feed is super simple.

the lsj rail does fit better, however im running a returning fuel system and the stock steel line just doesnt fit well. i was planning on using the lsj rail and removing the crimped on end and welding a cap onto it, then putting a fitting into it. the only thing i dont like is the angle of it, i dont know how its going to affect the flow at that end of the rail with a plate welded over it. thats why i grabbed the obx rail, looked like a lot less screwing around and a much cleaner look. i mean, i can make it work, but all i can figure out is to run a set of extensions on top of extensions, not a great option.

ive got an 03-05 return style l61 rail, the one that had the regulator on it. ive already got it converted to a cross flow rail with an aeromotive regulator. problem is the 03-05 used an odd length of injector.

I recall some one on Facebook saying it would not sit flush.

You can make the LSJ rail a return style. Lots of us have. That's easy. Also you can bend, or just simply cut the feed end off and reposition at will and add a an style end to it. I've done that to the evap line to use as my return.

hit up axlethered's build thread

Just weld a -8 bung on the feed side and -6 on the return side and roll............ That's what the cool kids do, at least.........

whos build thread? im assuming you spelled their name wrong, i cant seem to find that user name

if i have to use the lsj rail thats what im going to do.

i have a few issues in my swap with that sort of setup. im limited on room to put things, and the best location for my fuel regulator is sitting on top of the manifold (im running an lnf manifold). my plan was to run the fuel in the rear of the rail and out the front, use a 90 on the end and run it to the regulator. that throws the whole stock steel fuel line out the window, it just puts it all the the wrong spot. next problem is firewall clearance, you wouldnt think it would be an issue, however the firewall in the 944 is pushed back in the center, and the intake manifold is right against it. i have just enough room with my old modded l61 rail for a 45 degree fitting to clear everything. having the extra adapter in it puts the fitting in the firewall. i did spin up an adapter on the lathe to put it closer in, it clears, but just.

i screwed around with it a bit more today, im thinking ill just run a set of 12mm injector spacers on top of the injectors, shouldnt give any issues. itll all clear, and i just need to make some shims for the obx rail. its not the end of the world, just not the cleanest look.

You could machine some nice spacers. The thing about it being in the Porsche is that anyone who does notice the risers will likely just assume it had to be done due to the nature of the swap.

this fuel rail will not fit, it sits to close to the cylinder head and the valve cover bolts interfere with the mounting and the fuel line fitting can't even be installed due to how close it sits because the coolant temp housing on the cylinder head is in the way, even after extreme modification I wasn't able to make it work

well, it fits





i ended up using a set of 12mm injector spacers and modified a set of lsj fuel rail spacers to make it work. im using ID850 injectors, however this would be the same with any 60mm long injector (whats used with a stock lsj rail).

Nice! Looks good

ahh see im using 42lb injectors so it was too far away from the cylinder head to use the spacers, what injectors are those?

Sharkey

iTrader: (1)

those are ID 850 injectors injectors. they are a short injector with a long spacer to make them 60mm, the same size as all the injectors used in the lsj (33lb green tops, 42lb black tops, siemens 60lb, motron 80lb, you get the idea). i just added a 12mm spacer to the top of them to allow me to space the rail up higher to clear everything.

all the Injector Dynamics require spacers

Sharkey

iTrader: (1)

yes they do. the 850s are a 34mm long injector and come with a spacer to make them a 60mm long injector. they fit perfect in my stock lsj rail. to make them work on this rail i had to add an aditional 12mm spacer. i test fit an old set of 42lb stage 2 injectors with this rail today, had to use the 12mm spacer with them to make this work.

where did you get the spacers from?

Sharkey

iTrader: (1)

i had a couple laying around the shop, however ive ordered a full set from ebay. they are the same spacers used to make an id1000 standard length. http://www.ebay.com/itm/331130173889?_trksid=p2060353.m1438.l2648&ssPageName=STRK%3AMEBIDX%3AIT

the purple ones are the correct height

Sharkey

iTrader: (1)

the purple spacers are the correct height, for the stock lsj fuel rail. to make this rail fit i had to space it up higher to clear the head, and as a result had to add the red spacers to the purple spacers.
