V8 twin tirbo 33 skyline.

[ricknismo]

Has anyone ever heard of or done a v8 conversion in a 33 skyline.Either nissan or lexus.We have a little project on the go and want to do a 750hp rwd v8 twin turbo 33.HELP!!!!!!!!!!!!!!!!!!!!

[GTS-t VSPEC]

We've just finished a project using a Lexus 4litre V8 with T78 turbo into a Supra RZ.

What help do you need? What have you done?

hey rick you still got those wheels ? i need a set.

[ricknismo]

We haven't even started yet as we are trying to work out if it fits and if it is street legal in QLD. What sort of hp and dollars did your project have.

[GTS-t VSPEC]

Well we are tuning it this week, expcet about 500hp at the wheels, this is without cams or agressive tuning, we want a reliable package.

The 4liter in the RZ is ok as it is a 25% increase in capacity which is allowed, I don't think you can do it in your case unless you have engineering certificates.

As we already had the engine and turbo the total cost is mainly in man-hours. We haven't come up with a proposed cost yet as we still have to tune the car and finish minor issues.

there was a VK Commodore V8 twin turbo pushing 1200hp on the dyno at the summernats..... killed everyhting i was told

be nice to c somethin different tearing up the streets now and then

[ricknismo]

Funny that it was built up here in rocky.I've talked to him but its different when you can chop and cut at will for a drag car.

VSPEC.. I'm considering turboing a 1UZFE Soarer. Can you give me some details? Keen to know how much it cost, what you used for fuel management, details on the fuel system, manifolds, and how you decompressed the engine. Just a few quick details on each would be great, you don't have to write an essay.

How many psi are you running?

[GTS-t VSPEC]

Miles B,

We will be initially tuning the car with a very conservative setup of about 10psi, to see how it repsonds to tuning. We have a single T78 sitting infront of the engine, there is plenty of room as the 1UZ is smaller in length. Engine management is via an Autronic SM2, manifolds are custom made.

I will attempt to get some photo's and post them for you, and will give you an estimate of the cost.

Thanks! I was thinking about a motec m48 pro.. much difference?

Can you tell me what you did to decompress? Head gaskets or dished pistons... or something else?

[GTS-t VSPEC]

Miles,

We have left the pistons stock for the moment and just used head gaskets to decompress, although in the drag car we built using the 1UZ we have used pished pistons aswell.

The Motec will be good, don't think too much about the Autronic, too much mesing about.

GTS-t VSPEC,

would love to see the engine bay pics of the supra if you have some.

this project that ricknismo is talking about has not had an upper budget limit on it. any help you can supply would be appreciated, even though we acknowledge that traffic rules between the two states are going to be different, any tips on what stage a mechanical engineer should be brought in. i.e should they be part of the build up from go to whoa to ensure that money isn't wasted in the wrong area's.

has anyone else done this in qld and had it approved by main roads dept.

[GTS-t VSPEC]

BigRod33,

With our car the 3->4litres is allowed under the current legislation, therefore the engineer only needs to confirm that the power output on the car is supported by the braking system. We are expecting very few problems getting it over the pits, be we shall see.

I'll take some photo's soon and post them.

If ya gonna put a v8 into a r33 , use a nissan v8.

I know where there is a nissan cema vh41 if your interested.

I think he wants 2g for the half cut. PM if u want info.

I heard the motor running in the cut its quite impressive.

4 cams 48 valves etc etc and revvs to 7500 no worries. Which means would be perfect with a turbo.

Not bad for an 8.

[hitnrun]

ricknismo and BigRod,

You may want to pop over to www.performanceforums.com and see if anyone has done this before. May not be skyline related, but they would be able to help with things like eng. certs etc.

Good luck and let us know how you go!

[GTS-t VSPEC]

There is also an Infinity half-cut in town aswell, 4.5litre V8 from Nissan. It is always better to try and stick to the same manufacturer in terms of engine transplants, will have less hassles getting it licensed.

[ricknismo]

does anyone know if either will fit?

2 turbos and a v8 will probably be pretty tight.

[GTS-t VSPEC]

Why do you want a twin setup, a big single will definately do the job. You'd be surprised that the V8's are quite a bit shorter in length, and it provides quite a bit more room to fit things in.

I know that the Infinity has been done before, I wold stear clear of the Lexus V8 in a Skyline due to licensing issues.

[Guest BigRod33]

hitnrun, thanks for the tip with performance forums

GTS-t Vspec, once you have photos etc can you email me.

also, any opinions about which would be the better motor VH45 or VH41.

also any ideas about availability of aftermarket internals for either of these motors???

thanks for the juice so far

BigRod,

The car is at the tuners at the moment, so the pics may be another few days coming, but I'll post them for everyone.

I know that for the 1UZ there are lots of aftermarket parts, including a 5litre strocker kit, hell yeah.

For the Nissan engines there are some aftermarket stuff, but you would be better off having it custom made in Oz. For huge horsepower then the 1UZ is hard to pass on, with bullet proof internals, 6 bolt mains etc, and a host of aftermarket gear.
