R32 what? RB20DE, RB20DET, RB25DE, RB26DETT ?

they are all different is size, but all top feed, so no R33 will not fit unless its an RB26DETT engine you have.

you can not change size unless you reprogram the ecu either, so you must get the correct ones for the vehicle you have.

my advise is get a good s/hand set and get them ultrasonically cleaned if they need replacing for whatever reason.

hmmm thanks guys i mite go for the gtr ones ?

how much power can they handle ?

thanks

What motor do you have?

If you don't have the correct size injectors then you need a Power FC or the like - otherwise the engine will run very rich, it will look like you have a blown turbo

GTR injectors can handle high 200rwkw and maybe even 300rwkw.

You would need a resistor pack of some sort and a retune of the standard/aftermarket ecu to control the new injectors. You won't be able to do it on the safc as far as I know.

How much power are you making at the moment? And how much are you planning on making? You can keep the standard injector and make 200+rwkw with a good tune. Just make sure they're in good condition and are clean.

You can buy a genuine one for ~$120 or make one up yourself. If you want one made up, just go to jaycar or dick smith and buy some resistors and make them some how I can't remember. Try a search on the forums and you'll find all the information you're after. I think it was Roy who also made a tutorial on how to connect up the resistor pack.

The standard rb20 injectors are high impedance and the gtr's injectors are low impedance. What the resistor packs do is it increases the resistance for the standard rb20 ecu to be able to control the gtr injectors. It's something along the lines of that, not 100% sure though. You just need it if you've got the standard rb20 ecu and plan on running any low impendance injectors.

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
