Fuel Rail And Injector Choice

[Dan93]

Hey guys new to the forum and I've started modding my R33 GTST, so I've decided to go with the flex fuel option with the Link G4 ECU that's I've bought.
I've also bought a Walbro 450 E85 fuel pump.

I was recommended to get this fuel rail and injector package by my tuner so I want confirmation from you guys whether or not I should get it.

Mods are: pod filter, front mount, stock turbo (stock boost), 3 inch straight through exhaust with a decat, one hot dog and muffler.



For stock plenum. Top feed 1000cc injectors.

Why the hell not.

Well that's very informative.

i would be inclined to take the workshops advice given they will be doing the work and tuning it. you currently have only basic mods so it would be plenty.

Definately the best option going with that for the injectors only thing you will need to change on the aeroflow rail kit to fit the 1/2 size injectors on stock manifold is smaller spacers (8mm) and Orings for the plugs that go into the stock manifold are to big so you need slightly smaller diameter Oring.

Easiest way is talk to Scott on here or look at hes site http://scottyscustoms.com.auhe will sell you the kit with everything ready to bolt in at a good price.

Ok well the kit consists of everything specifically for the RB25det non NEO, so I would assume that everything that is in that kit is perfect for it.

Has anyone used this kit yet? Also it's $750. Does that seem to be a decent price for what it is?

Seems reasonable to me, what brand injectors? Bosche/ID??

Quite a bit of money for a modest performance increase (based on running E85) . You will need a retune. Why not wait until you get a new turbo? The new rail is not necessary but if you want one its not that expensive I guess.

Hasn't been tuned yet as that ECU isn't in yet. I'm doing the fuel setup beforehand so it gets done in one go with no retune needed.

What do you mean "I'm doing the fuel setup beforehand so it gets done in one go with no retune needed" ?

Does this mean you plan to drive around for a while with these injectors in without tuning it?

I will either drive the car to the tuner and install it there or I will do it all at home and then get it put on a tow truck and taken to the tuners.

[WantGTR]

you arent going to save much in labour. just take the car there and get them to install and tune.

That kit won't just bolt in, not unless they have made different rail spacers. Do you have a link? Where is the kit from?

Also the lower plenum adapters won't fit into the stock plenum without changing the Orings to thinner ones. The rail kits are designed for Greddy plenums.

Ah, Garage7 in the watermark. Ring them and ask? I doubt they will know what you are talking about, and it will be your mechanic's problem when it doesn't fit, which you will have to pay for.

[Dan93]

Alright guys thanks for the help. Has anyone dealt with garage7 in Adelaide before? They seem to be pretty damn good and a lot of help.

If you're on Facebook do a search for garage7 and look at their photos. Says it's a solution for stock plenum on rb25dets non Neo conversion from side to top feed.

[WantGTR]

if thats what they recommend and thats what you guys discussed/agreed on then maybe let them do their job?

[Ben C34]

As if! Random guesses are where it's at.

[Ben C34]

Garage 7 get alot of their own stuff made.

My guess is it will fit and work.

[scotty nm35]

Just looks like an Aeroflow rail kit to me, unless the pictures don't show the short spacers and second set of Orings?

I can only assume Garage7 are buying the whole kit including injectors from Aznew, which is my supplier, and they don't include either. I need to make the spacers to suit the short 40mm injectors.

Call them and ask, it's the only way to be sure.
