Single Or Twin Turbos

[75coupe]

You really need to think about what you want from the car, cause a car with 600hp (which is a figure you keep mentioning) wont be the greatest daily.

How much do you want to spend?

What are you using the car for?

Answer these two questions and i think youll get more specific answers.

I don't know the bolt pattern of the T78 of hand but anything in the PT range is good, probably a PT6262 will get you where you want to be

Or even one of the HTA turbos

Split T4

Thank you, look at something like this

http://www.precisionturbo.net/Street-and-Race/ss/600-800HP/details/Street-and-Race-Turbocharger---PT6262-CEA-reg-/245

With the T4 divided housing

I have always preferred twin setups for response but lately the tech in the mid to big singles is so far ahead they are possible beating twin ATM, and since you there it just makes sense to stay with what you have

Where are you located ?

Hopefully Mr Lith or Disco stick their noses in here they will have a better idea of turbos to use

Twinscroll = the twins you have when you are not having twins.

To get a reasonably linear 300rwkw plus, a pair of Garrett (stock replacement turbo's) GT2860-7

Hard pipe kit (need both):

Dump pipe kit:

I'd suggest the tomei dumps with a custom down pipes or a full greddy dump kit.

Get some stock exhaust manifolds, have someone port them out (support upwards of 500rwkw).

Similar dyno results can be achieved with a well chosen single turbo, however power delivery on the street is normally not as smooth as twins... it's the off boost to 'on power' transition where the real difference is in my option.

... btw the main reason I chose to link the products to Kudos is that they support SAU as well as being one of the only professional and customer focused parts suppliers for skyline parts in Aus.

I didn't say that to try to offend you, sorry if I did.

I have already given you the advice of taking it easy for a bit and doing some research. if it takes another couple of weeks it will be worth it, both better and cheaper.

No offense Ben, would not have stayed on this site if I took offense easily blokes say what is on their mind and I do the same, all good.

The trouble is knowing nothing is a pain and I have tried to look around and the more I look the more confusing it gets, someone will love a product and the next bloke will say it is a heap of crap, makes my head spin

Efr 8374iwg ( I think it is, might have those numbers wrong )

Friend has one on his gtr, it is a 3L, but makes something like 22psi before 3k and can go on to make 600whp.

Hi Richard, your numbers were right, I had a look at the Borg Warner site and that could be one I will keep in mind.

I did see they are Dual Row Ceramic Ball Bearings , I remember a post/s saying that these can brake up and enter your motor , or was that referring to a different type of ceramic part ?

[XKLABA]

Different part, what they were talking about is the factory ceramic rear wheel, they can break off and end up in your cat, I personally have never seen one go into a motor

I read something on the GTROC Forum , they did not mention Ceramic Ball Bearings so it should be OK

So I have another Turbo on my list , thanks

[tricstar]

^ what he said.

Also my friends car was still on 98 not e85. So still more to be had.

I doubt you'll find any other twin or single turbo/s with that sort if response and top end ATM

[ttoks]

unless, you want to build a 30/26

looking at the PT 6266 as most of the components of the T78 can be used.

Thanks for your input

Your most welcome

The one in the link I posted ?

I never saw the post. I will have a look if I can find it

Not that interested in the Dyno readings, I want to feel it on the road, No lag and responsive as possible from the start. Until you drive the car for a while it is hard to know what you want, I know now.

Been talking to Joey and he said that MAYBE the PT6266 could still be a bit big for what I want , quicker spool, mid range power that can still use the T78 components, anything come to mind?

I will keep looking and hoping for members to point me in the right direction. I am hoping to find what I want soon as I want to get the job done during the Easter School hols as I will have to take my kids with me to Sydney for a week while it is being done.

Thanks again for pointing me in the right direction and to get me thinking with the top head

[XKLABA]

What cams has it got ?

And what are you looking at putting in it ? And for god sake don't say type B poncams

[GTR_JOEY]

He has the type B's Mick, I recommended yavuz's cams but he will need the releifs in the head if they aren't already there

[XKLABA]

Oh yuk, get rid of them

I suggest the UE cams to every one, they are a good setup and if I had of put some more thought into my head while the motor was apart I would have a set

If you want to change cams with "boltins" then either stock or type R poncams

This was the info I got back? Too late for the Poncams B, BUT that is life

The engines are designed with a certain power band range when we design and build them .

The power band of the PTE6266B CEA SP is perfect for the engines power band range of 4500 pm to 85000rpm ( std engine rpm range is 4000 to 8000 rpm ).

There is a turbo that is one size down from the 6266 and that is the PTE6262B CEA SP. This will give you a similar power band range as the original engine ( 4000 to 8000 rpm ).

Keep in mind that the exhaust manifold will need to be modified to suit either new turbo set up.

That would be ceramic wheels on turbos, like the factory GT-R ones.

I'd be impressed if you could even break a ceramic bearing.....and even more if they could somehow find their way from a sealed bearing cartridge into your engine
