Twin Turbo System.


Alex

Recommended Posts

Hey guys. I have been thinking about it alot recently. I want to get a twin-turbo systme pu tonto my 350z. I was considering selling it and getting a performance car that is 4WD such as a Porsche 911 Turbo or the Audi RS6 (has to be estate). But then decided I will get a more practicle runabout for winter and save myself alot of money and get a car I already love with a TT.

 

Have read previous posts and considering taking my car to WRC Technologys metioned by urbanmyth and co. But I want it to be at least 500BHP at the wheels. so about 560-600BHP or so at the fly whatever it happens to be about. Does anyone know what would need to be done on top of the TT at arounf £8400-8500 and how much its likely to be about. (e.g. £10000-12000).

 

As I currently think the 350z is a class car. I have raced so many things and never been beaten,always been near neck and neck, I mean only yesterday I saw a brand new WRC Sti Scooby and soon as it got over a certain speed the car just anhiliated him, so a TT I think is the perfect solution to bring the acceleration to the high end speeds right up!

 

Many thanks guys! Alex.

For those kind of power levels, you need a bottom end rebuild and with the turbo installed, can't see you getting there for less than 20k

 

When Violent Racing wanted to come and install JWT TT on my car, my budget was £25k to give you an idea - they thought they could actually get internals etc done for £22k but I wanted brakes, suspension etc on top

 

And before you ask, the reason I didn't proceed was twofold

a) With what I've spent so far, it would've cost me £60k and they are much better things out there for 60k

B) I did not believe either with VRT's experience that the level of competence was sufficient to justify that spend. In the UK using a UK installer (assuming you have the cash) this should be your overriding concern IMO otherwise you're spending one hell of a lot of cash at very high risk of loss

Thanks for the reply prescience. So without going into crazy money what is the realistic BHP that I could apply for no more than 12-14k. Because if I was to spend 25k, if you add that plus say I could sell the car for about 18k that is aroung £43k that could easily buy a high performance car so would be pointless.

 

Many thanks.

I think that you can do Twin Turbos adequately with gauges, clutch, larger wheels for around the £10k mark. That will deliver a maximum I would say of 460 crank on stock internals. Your problem is to move over the 500BHp mark there is a step change in cost because you have to do engine internals (as a set) and that's where the expense mounts up. So I don't think realistically there is a BHp figure at the 12-14k level you indicate over and above that available for 10k.

 

Baptist might have a different view and his perspective would be useful. Jon, what is the minimum you get away with for internals (assuming a good choice of components) 8k? I still say that the cost/benefit is not in your favour at that minimum internal option though.

 

If it were me (which it sin't going to be now), I would be doing low compression bottom end, uprated head gasket, sleeves, probably cams, water injection plus brakes and suspension

So im looking at around 10k or so and being able to get round about 450BHP at the fly. So more than that would be crazy money..

 

See when I hear this I think, na sell it, but cause the 350z is already the underdog, and not laot on the road can push it around, 450BHP would make it a hell of a car which still turns heads, and isnt common as apposed to half the performance cars on teh market, e.g. scoobys and porsches.

 

Thanks for the help pre - will send a few e-mails and see what companies offer what, also it wouldnt be happening tomorrow. But I would like to see this happen before christmas for definate.

No way on earth would I run 450bhp on a car with standard internals. You could get that power out of the standard kit, but your engine would be on a knife edge.

 

The suspension and brakes, as standard will be well beyond their limits at this power output as well.

 

If you want 500 bhp, the turbo kits that are out there, need quite a few other components, as well as a built bottom end, to help you achieve that kind of power level.

agree on what Dorian said.

 

Another option would be to get a crated engine (already rebuilt) from the US (top spec, long block, ready to get the TT slapped on it and put back into the car) for about $13k plus shipping, VAT and customs and your block sent back, then you'd need a proper fuel system, clutch, suspensione and wheels. You'd then be able to go beyond the 500 number, well beyond. Mind you, over 600hp apparently traction is the issue, so not much point apart from bragging rights. And the £20k mark is about right for what I know.

or you could buy this one complete for less than £20k.

The guy selling this called me the other day and offered to do a p/x with my Audi Im trying to sell.

 

Sounds awesome but just a bit too scared to spend £20k on something I dont know enough about and might blow up, or kill me driving it!

 

I think a standard zed will do me for now.........

all this hastle :angry:

 

Because when I renew my insurance for this car, still full comp is like 45% less :yahoo: compaired to what im currently paying so it would be much much cheaper than buying something with 450-500BHP standard as 99% of them will be 20's on the insurance group!

 

Well as long as I can comfortably spend 8-10k and get round about 380-420 then I will be happy. cause I must not forget im in Scotland so Ferrari's and Lambos arent exactly common :teeth:

 

Only other thing can anyone recommend somewhere closer to home for me. And if your reading this Rev where is that specialist you take your car too? Would they do TT?

 

Cheers. Alex.

It all depends on how smart you are about it.

 

You can import a turbo kit from the states for about £3200 for the greddy of £3800 for APS of Power Enterprise. Some kits need a few extras.

 

The cost of fitting and a tune about £2000. Or if you are willing enough to try fitting yourself.

 

Suspension will be about £1200 - £1600

 

Or you could go to a UK company pay so that they make a mint on the kit then on the fitting and on the tunning and pay £8000+ just for the turbo set up.

Importing sound better to me :thumbs:

3200 for the Greddy?? you'll need more bits and bobs than the bare kit comes with, and does it actually fit the RHD car???

 

I dare say it will add upto more than that, especially when you realise that the Greddy is not a complete kit, by any stretch.

 

Do your homework, it cost more than you first may think.

Yea sa i said above.....Some kits need a few extras.

 

 

But many US vendors realise that they can now cash in on this and sell kits with the extras.

 

Alex: I fit most things myself as i own a bodyshop but allways trust Daztek to do tunning. They are prob the best in Scotland. Another company i use are Greer Sport they have worked on 1 or 2 350z's onw which had a turbo and supercharger that the guy built himself. Think it has loads of problems though.

Think the main parts for setting up a greddy tt kit are bigger injectors than those in the kit upgrade to 660cc. Power enterprise make the exact fit and better fuel delivery needs to be addressed a Walbro 255 fuel pump will fix this. Also to save the turbos a BOV helps fitting this should be cheap as its just a weld job.

 

From there its just a case of Good tuning. I have set up 2 other turbo charged cars that were not turbo as std and cant say how importand good tunning is.

 

 

Not saying i will deffo do it but if im going FI I will fit it myself then gave it tunned by some 1 else.

 

Im looking at the PE kit at the moment which is designed for RHD cars. This kit also needs the bigger injectors and fuel pump.

These are the basic parts for a GReddy set-up

1) Greddy Twin Turbo Kit with Front Mount Intercooler incl 440cc injectors

2) AAM Spec Return Fuel System

3) Walbro 255 Fuel Pump

4) Greddy Type RS Blow Off Valve

5) Greddy blow off valve flange

6) Greddy eManage Ultimate Main Unit

7) Boost Controller of your choice

8) eManage Main Harness

9) eManage Pressure Sensor

10) eManage Pressure Sensor Harness

11) eManage Ultimate Base map for 6-8psi

 

Around $8000 plus shipping and duty :)

 

You should also consider test pipes, hi-flow true dual exhaust and gauges as pretty much essential items

But does it fit RHD??????????

 

Good value kit if it does.

 

Well I confess, I did assume that that angle had been considered by Lew, but I did a quick check for myself and found this - the issue appears to be with the manifold

That was a while ago so Lew have you got suitable assurance from GReddy now :wacko:

surely if he sources this kit (like the PE) specifically (even still through a US distributor) for a RHD car, it should work? same for the APS one btw.

 

I don't quite understand your point? GReddy have responded (albeit a while ago) that it does not fit RHD, so he would need first to establish that they have produced a modified or a separate kit for RHD?

 

APS is different, their kit was designed for both LHD and RHD from the outset which is hardly surprising since APS is based in Australia and the US is their biggest market. Believe the PE kit is similarly designed for both :)

I am saying nothing of the kind because I don't know.

 

What I do know is that PE do LHD/RHD, APS do LHD/RHD and from a post in the Australia sub-forum of my350Z (link above), GReddy stated in direct response to a question to an Australian guy about the GReddy kit, that they do not provide a RHD kit for JDM cars.

 

You might doubt it, but the evidence is written there and needs to be refuted by GReddy before a purchase would be a wise choice IMO.

 

The issue I have seen elsewhere is due to the fitment of the kit with the RHD manifold :)
