Hey all.

I have searched the forum but cant seem to find a definite answer to my questions.

Im gettin a bosch high flow 044 and wonderin if i should be upgrading the regulator or the injectors?

I'm only after about 250 - 300rwkw.

I've been checkin out 2 different sard regulators;

1. Sard regulator 8mm Nipple( apparently suited to my power goal and I dont have to upgrade the injectors??)

or;

2. Sard TYPE-R regulator (apparently suited for higher boost applications and larger injectors??)

Any help is appreciated.

:D

You will struggle to get 250 out of the standard injectors without at least a new rising rate regulator. (and I wouldnt really consider 300)

If you are going to spend the $ requred to build a RELIABLE 300rwkw motor the $1000 (or a bit less) for new injectors will be only a small component.

Check out some of the other threads, but you will need to strenghen the internals (rods and pistons) turbo, intercooler, ECU etc etc. your up for several thousand to do this, then you have a problem of getting traction on a gtst with that much power.

If you want a Fuel Pressure Regulator Sard TYpe R, i have one ..

PM me.!! $190

Forget the regulator and just get bigger injectors. Simple! I'd probably avoid SARD as they are single jet type and not all that ideal for DOHC heads. Nismo/Apex/HKS make quad jet designs which are much better.

They dont hold there fuel pressure.

Or just get a SX.. double the price of SARD but better then ANY fuel pressure regulator in the world.

F1 car's use SX.

Cheers

Ya, a few guys have had problems with the SARD ones on RB25s

Nismo make 740cc only, but if you have a PowerFC there wont be a problem, and they are only an extra $50 or so over Apex/HKS 550cc ones so if someday you wanna go for 300-350 you'll be all set.

You wont need a fuel reg either. Im still using my stock one.

270rwkw - nismo 740cc injectors and no problems.]

cheerss - ash

been doin some more research and am curious if a set of S15 injectors would be more suitable. Apparantly these can fit straight on. How much power are these good for?? Can they handle over 250rwkw??

Also read that I may be better off goin for a gtr fuel pump. How much power are these good for?? can they also handle over 250rwkw?? how much is a good price for a gtr fuel pump??

With these upgrades would it be necassary to upgrade the AFM?? If so, any recommendations??

:)

Hmm, I was going to go for the 700cc Sards, great price from Greenline however this is the first time I have read anything bad..

Could someone explain this Single v quad issue to DOHC's heads?

Is this an *issue* or will it run well... or are we talking go for HKS etc...

Hmm confused now. R32 GTR

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
