Gtx2863 twins

[Taha]

Hi just seeing if  anyone has driven  a gtr with low mount  gtx2863r twins  or know what power and how they will drive  asking for  a friend  car currently  has t517s  on a built 2.6 with drop ins and a getrag 6speed 

[GTSBoy]

Have you looked at the thread?  The one at the top of the forum?  The one with all the RB26 turbo swap results?

[Taha]

I'll check it out  thanks

[sneakey pete]

Also there's a big Gtx2860/63/67 thread where some people have results

I recommend going twin scroll, single turbo setup if you want response, good transient and power.

It'll be crap to drive but make lots of power on a 2.6, those turbos are more suited to 2.8-3.0l

Whats his power goal? Drag spec or street?

Garret themselves state the turbos are no good on a mild 2.6

[Stixbnr32]

I wonder how they would go on a highly modified 2.6L in place of my -5's. 

Probably far to laggy.

I said there gonna be laggy but he is one if those gtrs came out with twins type lol ?

Street car  with a bit more punch then his t517s  he has a getrag so super short gears

Should be okay on a high revving 2.6, even still -5s on e85 would be better

To the OP: Better off getting HKS 2530 or -5s if he is staying on twins. 

[Stixbnr32]

Yeh I am formulating a plan to switch to E85 on my -5's.

Bet these are far to laggy for a street driven GTR.

I am getting some -5’s upgraded by MMP turbos to bring them into the 21’st century. Ceramic bearings and modern turbine and compressor wheels. Am expecting a combination of better response and a broader power band. 

Luke is super keen to share his knowledge and see how he can make the turbo best suit your goals. 

[sneakey pete]

What compressor turbine wheel are they using?

[Stixbnr32]

That is real interesting.  Please post before and after results.

I might talk to a well respected Turbo builder in NZ and see if he ca do similar before I go for a tune.

I’ll need to get some more technical details as I’m not exactly certain. Turbos being sent off next week. 

Image below of ones prepared last year for a customer. 

I already have the turbosmart IWG75 actuators on my current -7’s with a 20psi base pressure, so once bolted onto a mildly ported head with some higher lift cams it should make some stout numbers.

As I’m changing turbos, cams and getting the heads ported I don’t feel there will be an accurate comparison but here is the results of my current set up. 

Highflowed -7’s

kelford 264 8.9 Cams 

plazmaman 76mm intercooler

E85

What do you mean by 'Highflowed -7’s' ???

Billet wheels or?!?

This is what I've been talking about doing with the turbo guru here in S.A I believe...

Basically taking some -5's and putting billet wheels into them...?!?

[burn4005]

There is a reason all the new tech compressors come with anti surge housings and it isn't for looks.

updated to lager billet compressor wheels.
