Hey all

Have a r33 GTST series 2 track car.

Just bought a plazmaman Plenum and a HTA3076r turbo.

Changing injectors and fuel pump at the moment. And will be running E85

Im going for some 1150cc Bosch injectors and walbro e85 pump.

My question is, is it as easy as just buying a plazmaman top feed fuel rail and bolting it on to change from side feed to top feed, for the injectors?

Or is there more to it?

Any advice?

Is the Plazmaman fuel rail a good bit of kit? or anything that would be better?

Cheers

There are plenty of fuel rail kits out there, Plasmaman being on of the more expensive ones. I guess you are guaranteed it will fit under the plenum, although I usually recommend the Proflow ones since they modified them slightly to fit the RB25 better.

What the hell is a 1150cc Bosch injector? Seems every supplier is bumping the flow numbers just to make their stock sound better. At what pressure does it flow 1150cc? I assume we are talking about 1000cc EV14's here? If you are running e85 have you looked at the injectors designed for that? (Xspurt 1400's and ID1300's)

thanks mate.

Will have a look at a proflow ones. do they have a website?

Umm the injectors is bought here from a business trader.... 1150cc BOSCH injectors, E85 compatible

i have only part paid for them at the moment.

But im more not happy if the trader has said they are bigger then the 1000cc ones, plus paying slightly extra when they are 1000cc ones. plus they claim them to be good for e85

The injectors I have seen that care 1150cc are at 5bar pressure.

Ask them at what pressure they flow the claimed amount?

If you look at the id1000 injectors for example, they flow pretty much bang on 1150 at 5 bar.

That came out shit (on mu phone)

Look at the left column for pressure and the bright column for flow.

5 bar is pretty much 58psi.

3 bar is 43.5 which is the standard when specifying flow.

Thanks mate.

I know my GTR has 1000cc Bosch injectors and has been running E85 for a year and a half now. makes 389kws at the 4s. Im unsure of the head room of the injectors.

The gtst will hopefully make around that mark also. So for what your saying for the set up the 1000ccs and the 1150ccs are either the same injector or on a normal set up will flow the same?

bosch is ok with e85 tho correct? with stainless insides?

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
