Injectors

[zentac]

In currently running the sard 540cc (that are detailed on here somewhere) they are at 70% capacity at 411bhp so are there any larger ones 750-1000cc that plug straight in?

[Nick Mann]

So you want more than 530 then? I thought 90% is still okay....

I can't answer your question though.

[Turbo_Steve]

Well SARD do all sorts of sizes, so if you've got them in a specific shape they are bound to do them larger. The problem will be sourcing them, I'd imagine.
Sorry....not really very helpful.

411hp at the wheels?

Im in the middle of moving up from a GT28 to a GT35. Ive seen graphs of EVO's with 700bhp on race fuel with the same turbo Im going to be running - I need bigger injectors :D

nah fraid not, turbo ran out of puff.... at 1.5 bar :(

Dont know the specs, but i think Valmes is running 800cc ones. Plus i remember reading somewhere that GTO injectors can be made to work? If you have an after market computer, could you get Evo injectors to work with the low impedence?

[Nutter_John]

Yeah seeing as your running a standalone you should be able to switch between high and low injectors with no problem , there are plenty of 1000cc ones out there you could use , you just need to mod the fuel rail to suit the size and height

[zentac]

yeah i know that, I was kind of asking are there any that I dont have to mod the fuel rail. I would like an easy life once in a while when it comes to this car :)

[Nutter_John]

ha ha I can understand that Rich :D

Just putting some info together here!!!!!!!!!.
The ones we can use are Toyota soarer 530cc are top feed high impedance.
I am sure I have seen top feed, high impedance injectors on RHD Japans website, 800cc and 1000cc, not sure if this is logical.
(ones listed for toyota soarer are also suitable for other toyotas, supra are high impedence but side feed!).
Just thinking aloud here!

[bradc]

I'm surprised you're at 70% on the sard injectors that early. how much hp at the wheels?

[zentac]

348 Iirc

[zentac]

Ive just emailed sardracing.com to see what they come back with.

[Eurospec]

Just make up spacers for the rail, then you can use the much more common and easily available (about to get it wrong way round again) high impedance ones a la evo, gto etc.

Failing that 3sx performance sells the low impedance ones, but i cant recall the size.

Cheers,

Ben.

63565 (6 X 800cc) Nissan Skyline HCR32 RB20DET - 800cc - Top , High Impedance, 2 Hole, Time 1.6 msec

these should work rich with a little mod to the fuelrail

[zentac]

I got a mail back from sard, they dont do any larger ones than the ones I already have, I tried some evo ones today and looks like they should be a decent fit.

[Louis]

THe Evo ones being low impedence cause probs with the factory ecu, can your ECU, adjust for them? (can't remember what you are using!). Someone here was running the evo injectors ok for a while. but then burn out the resistors!

[Turbo_Steve]

That's fairly easily remedied: you just run an external resistor pack. Bit of a pain doing the wiring: about 3hrs work to do it properly.

[bradc]

Doesn't matter for Richard, he's got an Autronic like me.

[zentac]

Im running an SM4 so shouldn't be a problem. Dont think I will need resistor packs either

[Louis]

cool, Is autronic sm4 the one that doesn't like autos?? ( about to do a search now!)

[Gly]

yeh its has issues with autos

[bradc]

well the people who setup my ecu couldn't get it working. It should be possible however to link it up with the stock ecu and trans ecu to get the gearbox to change gear.
