So I’m upgrading intercooler and fuel hanger/pump, have 1000id injectors e85-9 Garrett’s making 320awkw currently.Will upgrades to cam gears and type B poncams assist much in power gains on my Gtr32.

Im going to tidy the engine bay by powder coating the cam covers and figuring out weather to upgrade at this time. Advice would be great.

Hi again Matty. Just do the cam gears and keep the stock cams with your -9 turbos. If you cam it you will absolutely make more power, but your car will be slower everywhere except the drag strip.

Your call

Don't get Tomei cams if you're wanting new cams, get some decent Kelford cams, an intake cam gear (advance its mum) and install new valve springs (avoid Tomei junk), retainers and valve stem seals.

Yeah but with -9s car will still be slower for a streeter, even with the most baby drop in L182-A Kelford cams.

You're right though with the Tomei valve springs, how shit are they ? Caused me nothing but problems. The Tomei type B is, how did you put it, "made from a child's faeces"  😂 That still cracks me up.

That's correct, longer duration will move the torque/power to the RHS, however will also introduce more torque/power. This is where the intake cam gear comes into play, advancing that intake as much as possible (within reason) will pull that power curve back and the net result is nearly similar low RPM driveability but now with a wide power band :)

A bit of a balancing act.

Tomei cams & Tomei valve springs should not exist lol

Yeah I've played with this on my -9 33 with this with Tomei cams. Ended up going back to stock cams with I think about inlet advance 4 and exhaust cam retarded 2 degrees.

I think -9s would actually respond to a 10mm+ high lift cam with less than 260 duration, but most people are not going to do such big head modifications with such small turbos, or twins at all.

You are completely right though, but cams just not worth it to increase 10 - 15w at most top end.

when you do end up picking a set of cam gears i would go with the kelford ones. i think there the only cam gears with the 5 mini helicoils and seem very high quality compared to tomei hks etc. cheers

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
