Almost time to get into these injectors but need some real world info about types and sizes . I'm leaning towards Xspurt 750s because I want the shortest ones to fit under the standard R33 plenum chamber and 740cc side feeds have been proven to get to 360 RWKW on Guilt Toys RB30 with E85 anyway .

I can't see a 300-320 RWKW RB25 needing any more fuel and I'm thinking anything larger may start to lose the down low mixture control and transients I really want to be really good . In fact as sharp as possible because I want to run lean clean mixtures at part throttle and cruise . I want to see numbers like 1 plus lamda at these times because my 25 really likes it when I can get it to do it which I can't consistently ATM .

There is a lot of hype about ID injectors and I'd probably pay for their ID850 GM injectors if there was a local supplier who kept spares . These are short EV14s that fit in late model Chev V8s and should work fine but there HAS to be local support and replacements available .

So far I haven't seen shorty 1000cc EV14s which is surprising to me anyway .

Plan is to modify a GTt rail which has two heavy duty "L" shaped brackets either end to bolt it down . From memory the rear one is slightly offset between the 5 and 6 injector mounts and needs some alterations to fit an R33 manifold . Also I believe one of the tubes possibly the return needs alterations to clear something under the plenum .

AFAIK the worst thing Nissan did to an R33 was fit SF injectors , cheers A .

The Xspurts definitely come in 44mm 1000cc. As they are the same price as the 750's I would just go the 1000's.

I saw a set of 1000's maxed out at 330wkw the other day on an auto RB28. It's not something you want to deal with twice...

Side feed injectors were good in their day, better than the low impedance 11mm top feeds anyway, but they are well past their used by date. Even the EV14's have been superseded by the new stainless internals ethanol/methanol compatible injectors now on the market.

Looking forward to pics of the GTT rail install, it is going to be the best of both worlds, stock looking and 14mm top feed so there are a heap of injector choices.

Why were they maxed out at such a low power level? I understand the auto box will give a lower power reading but that's still awfully low to have them at 100% duty cycle?

I couldn't find much info on stainless injectors aside from ID1300s but I think they are a bit big for mostly general use . Maybe in 500cc/pot engines but 415 - dunno .

At one of the OS forums I was reading that Bosch doesn't make Motorsport injectors larger than 1000cc and those with more flow are all modified in the aftermarket .

So I suppose 750 - 1000cc shortest EV14 is the go unless you know of anything better .

Bosch make the ID1300's though.

I spoke with the wholesaler when I found out about the new 1400 stainless internal injectors coming out onto the market. They are a Delphi version of the ID ones. They were designed for the V8 supers, as ID have a contract with Bosch not to sell directly.

Delphi are also spending a lot of coin lately on ethanol injector research, the most important of which is a controlled heated tip injector, designed to pre-heat the fuel as you crank for cold start. It should negate the need for cold start enrichment entirely, and allow instant starts in subzero conditions. I have politely asked their Brazilian connections if we can have this technology installed into the 1400's, hopefully something comes of it as I really chug through the fuel on cold start/running.

Arts no I don't have any Toyota pistons , only JE VG30 ones .

I'd like to try the GTt rail but your set up may be attractive if you have all the rail mounting hardware and manifold collars . I didn't really want an aftermarket reg but I suppose its part of the set .

Scott I did find mention of an Xspurt 900cc short EV14 on an NZ site , maybe these are known as 1000cc over here and similar to the ID850GMs which are short EV14s for late LS Chev apps .

i actually would prefer to keep the reg...i didnt know Scott got the r34 rail to fit...i was going to do that but couldnt find a neo rail cheap enough at the time to warrant not just buying an aftermarket one as i got a good price on it i also wasnt sure if it would actually fit, it looked to bulky so didnt want to waste the coin buying one

anyway I'm not fussed I can just use these injectors on my 1j. but then the rail goes to waste..anyway whole set is there with collars and all.....but if you can get a NEo rail in and dont want the bling, may as well do that i guess,at least you can use its factory reg as well

I am about to install xspurt 1000cc in std gtr fuel rail with std reg on greddy plenum. Will be doing a how to guide.

Could mod one to fit std manifold.

yeah Mark already done it and posted result in my how to tutorial thread...was a bit more work as he ended up having to mod the plenum ..where the shorter 750s fit in nicely

Scotty is confirming that Xspurt do a compact 900-1000 cc EV14 and if so that's what I'll buy . Big enough but not too big for an RB25s 415cc pots because I want it nice right down low . I want them to support 320 RWKW on E85 and not 100% sure 725/750s would do it .

I have seen adds from KPM (SA?) of 900 and 1000cc compact EV14s but not sure who supplies them . It seems there are lots of fake or dodgy EV14 hi flows getting around so given a choice Xspurt or IDs sound good to me .

I would have thought that there would be more of these 800-1000cc EV14 shorties available since they fit the 6-6.2L Chev V8s , maybe they aren't into ethanol so no market for them .

Anyone anywhere can criticise anything but here at least the Xspurts and IDs generally get a good rap here . Just as many people rag Deutchworks EV14 high flows as like them but some claim flicking them for same sized IDs made a noticeable positive difference . Xspurt is local meaning local spares , I doubt it's an economic proposition sending an injector back Stateside for exchange .

Insight Motorsport is at Arndell Park and he is a ID rep, I got my ID1300s from him when they where first released

The ID1300s are made by Bosch under licence to ID so I would be interested to see if you could buy them through Bosch or any of their dealers that aren't dealers of IDs
