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.

Nissan VR engine

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.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
