hey blokes looking for an answer to a basic q but just dont want to spend all night looking for it if possiable

mate has a 300zx 31 model vg30 he needs a set of injectors and was told only nismo items will fit due to the fuel rails ok thats fine but what size do nismo items come in? and are all nismo items interchangeable within all nissan stuff ie skyline,silvia,180?

whats the price(reasonable price) on a new set?

price on a 2nd hand set?

thanks guys

Nismo injectors, 555cc for VG30 are around $1300 on tweakit.net - as far as I know, they are all copies of japanese 'denso' injector styles, which all RB engines also use.. depends what the fuel rail diameter is (common sizes are 10.5 and 11mm). Also depends specifically on the year the engine was built and if its NA or not. My guess is any replacement denso injector will fit.

The VR38DETT engine

The VR engine is a 3.8 L V6 piston engine from Nissan. The engine is the product of further development of the widely successful VQ engine series, in particular drawing experience from the JGTC racing engines as well as Nissan's VRH engines from vehicles such as the Nissan R390 GT1.

VR38DETT

This 3.8L twin-turbo DOHC V6 engine is rated by Nissan to produce 485 PS (357 kW; 478 hp) at 6,400 rpm and 60 kg·m (588 N·m; 434 ft·lbf) at 3,200-5,200 rpm in its use in the 2008 Nissan GT-R. With turbos, the motor weighs 608 lb (276 kg).[2] It is so far the only version of the VR engine in production.

while on the topic of injectors.

If i put on a ebay style plenum on a 25 neo, and a aftermarket fuel rail (top feed - theres one on ebay that says it suits r32/3/4 GTR - would it work with neo ?) would i be able to use r33 gtr injectors ? And would they be good for roughy 280rwkw ?

Also what type of FPR is best to use with the above ? Stock or go a/m ?

Are GTR plenums going to work on a non-GTR? GTR are individual throttle body arent they?

Sorry if I'm guessnig wrong but if this is a road car, aren't these mods gonna turn the car into defect central?

the plenum itself, does it come with the throttle assembly too? Sometimes the plenum upgrades are just literally the intake manifold without the throttle bodies as they assume you already have them... cant use GTR injectors because there is a latency difference..... not sure about how it'd work as I know nothing about NEOs sorry.

Its a JUN style plenum for an RB25 off ebay, i would use stock TB. Now if i have a bare NEO, what injectors would i put in there for roughly 270-300rwkw ? As in, if i get an aftermarket fuel rail, can i get it to work with GTR 444cc's and be ok for >300rkwk ? (Obviously tryng to do it on a budget)....keyword trying lol.

jrm: not looking to use a GTR plenum.

Cant wait for the next couple of days to be over.

All my seam welding and fuel cell mounts and subframe bracing will be done :D

Also brought another 2 fuel pumps :D 2x bosch 070 as a lift pump from the 57L fuel cell to a 4L swirl pot, then 2 x bosch 044 to a twin entry fuel rail to Bosch 1600cc injectors, with a sard fuel pressure reg.

sounds good, you think the sard will return enough fuel tho, I just switched to a turbosmart 1200, also running twin 044's as a feed, but into 850 sards, only just got it running and seems to be nice and rich on e85, once I've finished fine tuning it i'm guessing ill have around 85-90% duty at 400 ish rwkw.

Lol I gotta set some standard for skylines in Adelaide lol.

Priced up some top of the line ohlins coilovers. Full remote canisters, adjustable, just under $6500 :)

For that kinda money I'd be getting some quotes from Drummond Motorsports.... they make some pretty sexy shockers

    • So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit? 
    • Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
    • I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
    • I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.
    • Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
