T04Z Help

[GTRR]

Hi Guys,

I'm seriously new to all this power stuff, the highest power output i've achieved was 200kws from my GC8 WRX back in the days with a VF34 turbo and supporting mods so anything over this is VERY new to me.

Been reading up alot on the T04z where there are many different opinions in regards to response and power it will make.

What i want to know is, is it possible to run a HKS T04Z turbo kit (comes with all the parts, front pipe, manifold, etc)on a standard R33 RB26DETT with supporting mods and gaining around 350kws or so? Will there be any chance of wearing out the motor sooner, is there such thing as running safe with that power output without the risk of damaging anything?

How responsive will it be on the standard motor?

And in the long run, if i wanted to rebuild the motor, will the HKS step zero increase its response and power output?

I thought about getting just the garrent -7 or HKS GT-SS but I know i will be chasing more numbers so maybe just get right to the turbo and be happy with that?

I've seen a R32 GT-R run 340kws with a HKS T04z however i don't know if it was responsive?

Any help and suggestions would be greatly appreciated, in regards to either the T04z or the GT-SS.

Thanks

go -9 or -5 if you want the ability to get around 350-400kw at a later time on a built engine, TO4Z is really a ~450kw turbo

I have a T04Z on my R34 and it makes 387kw on 98 octane and 460kw on Sucrogen E85 (30psi). Then only mods we have done to the engine are a set of cams, nitto head gasket and ARP head studs.

If your goal is 350kw, I would recommend the GT35R. You will have about 400rpm more response than the T04z and it will be the same response at the GT-SS yet make WAY more power.

T04Z is not the turbo for under 400rwkw.

On PULP I've seen them make 440rwkw so its certainly NOT the turbo you want.

GT-SS (-9s) are 330-340rwkw, T04Z is 450rwkw

So you can see there are two ends of the scale.

If you want a single, GT35, or from recent reports - GT3788

For twins, -9s

Put it this way - 2 simple questions.

1. Do you WANT to rebuild soon?

2. Do you HAVE 7-12k sitting there to do it?

IF you answered NO to any of those... Settle for a nice safe power level around 300-330rwkw. A street GTR with 300-330rwkw is reliable, and most of all it's super responsive. Take one through the hills with that response and you'll always be pleased.

If in 2 years you decide you want to get a bit more serious then just sell the turbos you have.

You'll get far more enjoyment out of a setup that is suitable for the use, rather than bolting on big turbos now because you "might" or "maybe" will chase more.

In the grand scheme of things swapping turbos out, when rebuilding - it's going to cost you 10% of the overall budget, which IMO makes it a non-issue.

Suitable package now, and suitable package later = happy times all the time.
