If you're willing to shell out for a quality exhaust manifold, why cheap out on the intake manifold? Go for a Plazmaman one. Don't waste your time with these.

R33 exhaust manifold studs should be M10 x 1.25 (fine thread). Going to be replacing mine soon as well.

Yeah I will need one. Sent you a pm mate.

Still heaps around. Just the owners have changed from people having a go with projects and sending them around a track to people treating them like an investment/status symbol to just be driven every couple of weekends and collect dust in the garage. No matter how much people value them, I'll keep having fun with Jap crap until I cark it. Also, eff the Americans for ruining the fun.

I'll give EFI a ring on Monday and ask them when they'll have the injectors that go with their kit back in stock. As for the harness, I don't want to stuff around trying to get stuff out of the USA but thanks for the suggestion. I probably will just wait for EFI to have injectors back in stock so that I can run their full kit. Looks like I'll be going with the FPR800 then. I hadn't begun to think about potential issues with running the 460 with my setup. Thanks, will likely be going with the 255 then.

Is that all he meant? I knew I'd need to do that anyway and replace the old gaskets while I'm at it.

Those comp test results seem fine considering its condition and K's. You probably already know but values can vary with different brands of comp testers. Like admS15 said, up the boost and send it.

Thanks mate, I thought so. Budget for the injectors and related components would be roughly 1K. I'm trying to do a relatively cheap bolt on build but without lacking in quality. I've been looking at a Turbosmart FPR800 which would be around $200. Anything cheaper/better? Will probably grab a Walbro 460 instead over the 255 since there's not a huge difference in pricing between the two. I would too but the Bosch 1000s that go with their kit are out of stock, which is why I've thought of going to Goleby's for the injectors. Not sure what you mean by split the intake plenum for fitment of the fuel rail. TAARKS claim that it's a 100% bolt on kit. Do you have a recommendation for a bolt on kit? I also saw these "plug and play" Raceworks injectors on ebay: https://www.ebay.com.au/itm/Set-New-1000cc-BOSCH-Fuel-injectors-E85-OK-for-R32-R33-R34-RB25DET-Skyline/171812524122?hash=item2800d3105a:g:b~0AAOSw7fJgRxkm Anyone had experience with these?

G’day, I’m looking to get some more power out of my R33 GTST soon (about 260rwkw) with some bolt ons and I have a couple of questions for those in the know. I’m still in the part collecting stage. With regards to fuelling, I’ve done a bit of research by rummaging through old threads and I’m leaning towards some top feed Bosch 1000cc injectors with an aftermarket fuel rail. I’ve chosen to keep the stock plenum and I just want to make sure that I’ve got the right options down before I order. I was thinking of getting the fuel rail kit from EFI Solutions: https://www.efisolutions.com.au/top-feed-fuel-rail-kit-rb25det-r33-c34 and a set of Bosch 1000s from Goleby’s: https://www.golebysparts.com.au/products/bosch-1000cc-980cc-1150cc-fuel-injector-e85?variant=29908789297261 For injector length, I have chosen 3/4 length 14mm and for connectors & adaptors, I’ve chosen Nissan JECS to Bosch Injector adaptors. Are these the correct options to plugin to the factory harness and to clear the stock plenum? I just want to be certain before I go and place and order only to find out that when I install the injectors, they don’t clear the plenum and I’ve chosen the wrong adaptors. From what I’ve read, I’m pretty sure I’ve got it right but would like confirmation. From what I’ve read, I think that I’ll need an aftermarket FPR or will the stock one be sufficient? If I need an aftermarket one, what would you recommend? I’m also thinking of getting a Walbro 255 from Goleby’s. Is there a better choice? Keen to hear some advice. Cheers
