This is the best place for research... There's blokes here building engines left right and centre!

so 8.5mm lift cams could go straight in ? what's the best duration to go with this before street driving is gone. i.e. reasonable fuel consumption and smooth idle. I was assuming at some point you need the extra lift for the longer duration to be beneficial !

Where's some good places to hunt down used injectors.

what about price ?

would it be sufficient if bigger ones went in with the stock setup or is it a must to go a new rail ?

what spec cams are you considering ? my mechanic thinks the 256 deg is the best for street driving. longer duration needs more lift to be optimal.

how big are the stock ones anyway?

Would you expect the need to increase the injectors for the GT35/40 and better cams ? Apparently the ECU needs upgrading as it only supports multipoint. This I'm unhappy about...

thanks for your advice mate, I'm gonna take it. GT40 & cams to come later after run in. Do you know if the GT40 can stay as a low mount ? Don't particularly want the expense of a full kit! Still unsure which cams though. Regards.

You got a contact number, and thanks..

You think so, I believe it's a high flow T03 , can produce 32 psi but loses spark at 22. I would've thought it could work better with the new engine. Want to achieve around 320rwkw. Also safer to run in the new engine with the smaller turbo. Will want to upgrade later though $$$

ok, height issue sorted , thx. If I don't need a plenum then I'd like to consider cams. This is it so far.. Engine is going together today for the first time. R33 gts-t series 1 head onto RB30DE block. Car already has, Haltech ignition & E6K ECU, 500 hp fuel pump& regulator,surge tank Series 2 gearbox, full size front mount intercooler , cold air box& unifilter 1200 kg clutch ,machined flywheel Blitz Dual SBC boost controller Hitachi T03-T04 turbo + 500 hp ball bearing core HKS 3" exhaust + 4 1/2 " tip Previous best was 247 rwkw on 12psi but had more and went better at 18 ! Now going for forged CP pistons 8.3.1 cr ,and REV rods together balanced within .25 g Chrone forged rings New bearings, main studs N1 oil pump and N1 water pump Block fully dipped and prepped from scratch Head work Keeping stock springs and lifters but considering Tomei 256deg Poncams. How much of a difference do you think the cams will make to this, considering another $1200 - $1400 for them. Or are there better ones for max improvement before street driveability goes down. Several opinions would be appreciated ! Regards

bl4ck32, Am I still up for a new top half plenum , one that's not as high ,or can strut brace be modified? Might be pushing the budget a bit now. Regards.

also looking for specs of various cams compared to stock. I've searched everywhere for before and after reviews but still nothing. Regards.

could anyone tell me of the best cams to use, the most aggressive before you've gotta do the springs and lifters.
