Injector Upgrade Problems

[mistermeena]

please help this is driving me nuts lol.

I'm upgrading injectors and I can't get it to fit. I bought a raceworks r33 rail kit, and xspurt 1000cc injectors. First I tried fitting it with the injector collars but the stock plenum fouls on the top of the rail. So then I tried plugging the injectors straight into the rail (without the collars) and it still wont clear the plenum! I'm sure that I've seen heaps of people using the raceworks rail and xspurt 1000s so I don't understand what I'm doing wrong. Any advice? Supplier said he sells many of these exact kits to fit r33s without issues. pics below.

To fit the injectors under the stock plenum I believe you require 1/2 length injectors.

Injectors are too tall

You can shave down the plenum and relocate a few things or just go aftermarket.

ah bugger I was told this kit would go straight in. In that case does anyone sell the shorter spacers that go under the bolts to mount the rail?

It doesnt look to me like I can shave the plenum back enough to make it fit.

You need the half height injectors too. See Scotty for what you need and sell off what you don't.

You'll need a new rail if you want to use those injectors or go half height injectors and use that rail but you'll need to cut down the spacers.

Or refund it and get what you were oringally promised.

I done this before with a cheap rail, it can work, it isn't easy and in the end we talkin bout a few mm of it fitting.. it probably will require some custom welding of shit/shaving to make it work

Should have just gotten 1/2 height injectors to begin with lol

[AngryRB]

Here is one i prepared earlier lol..

You can see the pipe underneath was removed and brass fitting installed uptop to make that hose easier to get on, and some shaving near that welsh plug, a fabricator can do this easy or if your local you can have this one...

or sell the lot/return it and get a kit that fits without any mods to the plenum LOL

[AngryRB]

Yeah if you can return/exchange then definitely do that... there is almost zero room even with the mods, takes long time to fit the thing up

[mistermeena]

yeah the seller is exchanging the injectors for the 1/2 height ones instead, and I'll just have to take some careful measurements and get the spacers machined down. I dont want to be grinding and welding on the plenum when I know that there are kits that fit straight in and I don't want the rail too close to the plenum anyway

[Dose Pipe Sutututu]

you can simple just chop them with a grinding disc to save money...

I would give you my measurements but you have a different rail with the protruding part per injector.

[iruvyouskyrine]

Just buy a shitload of washers and use the required amount. Then measure total amount and cut spacer to suit.

[mistermeena]

That's a decent idea haha easier than getting verniers in there I suppose. Can't do much until the injectors arrive now so I guess the car is on stands for a while longer.

cheers guys.
