Vq Build

[adzr33]

Hi guys,

I am in the process of getting a single turbo and am looking to get some boost into the vq.

I'm hoping to be able to run 10-15 psi. I am looking at buying the following.

Turbo kit (unsure which yet but want a single)

Larger injectors

Larger fuel pump

Stronger rods

Lower comp pistons

New button type clutch

And a up rev tune

Does anyone know if I will need any more internal mods or will this suffice.

Any help is greatly appreciated.

Will post up pics of build once it begins

Sooooooooo can't wait.

Kind of depends on what power your aiming at? rods are the VQ weak point and a set of low comp forged pistons are also good, whether you will need more will depend on your BHP goals, i am not sure if the valve material is up to turbo combustion temps?

One other thing you will definitely need is a complete fuel return system as the VQ doesn't use one, a decent adjustable fuel regulator as well, how are you planning on coupling one turbo to two headders?

I have a spare set of VQ25det manifolds here if you are interested, Single turbo and bolts up to the VQ35, same manifolds HKS used...

I can even help with the turbo and fabrication work seeing you are local, PM me if you are interested.

No worries sorry dude just moved to Perth. Haven't changed it yet. Not sure of goals to be honest was thinking if I can get to that boost safely I'll se what happens. Then I don't have to open the top end up. Something else to play with later lol.

I was just gonna buy a bolt on kit with everything.

If u can help with fab I'd be happy to try price it all up and pay postage tho.

P.S Cobey is selling his complete HKS 3037 Turbo kit with fuel pump, gauges...

Great write up as I will be embarking on my engine build this year. Quick question, I've already got all the ancillary stuff in place and I'm currently looking at a clutch/flywheel combo to suit and then I will have everything in place ready for the extra power. You seem to have done a lot of research already so what would you recommend?

If your going to do clutch then what i researched was:

Part Number: 6072-2100

Street Series 2100 Clutch Kit. Stage 2 - Steelback Brass Plus Clutch Kit

Part Number: 2-350Z-ST

Forged Lightweight Steel Flywheel

FW Weight: 18.65lbs (SOME ARE LIKE 8-13LB which is too light and will give you chatter, this one close to stock as possible)

Reason i went Competition Clutch was due to their high torque and HP factor (550-600?) and close to stock as possible.

I didnt get them from here but this is the ones

Make sure you also get

New Slave cylinder

Alignment tool

Stainless braided clutch line

Pilot Bushing

Chromoly pivot ball
