Gtr 4 Inch Exhaust?

[Griffin]

yeah they do choof a little but i like it like that.

[N1GTR]

You'd be the only one on the planet that does!

Where they're choofing is where you should have a hard surge of power but because of the mismatched wheels they cant get the power out. Its like the power is in there trying to escape but it cant, if that makes sense

[Griffin]

]here are dyno printouts, had to take photos of them. Mainline dyno reading is 10% lower ,though its the same car with same tune.

Wow 180rwkw @ 5000rpm...

You could make 280rwkw @ 5000rpm - with a simple turbo change, and have the same peak power on 20psi...

[Griffin]

really??? With smaller turbos what top end could i get considering ill fit injectors at the same time and a tune. Or will i be better off making the most of what i have.

Its only a weekender and i dont mind the way it drives now but is it worth the expense of buying new turbos? Which ones should i get by the way?

[SiR_RB]

What diameter front pipes do you have currently with the -10 turbos? And what size merge they got?

Top end will stay the same.

You need to run 25psi+ to make use of -10s

20psi is just a warm up!

IMO, the turbo change is the better option. That said it is also the most expensive so only you can decide what suits you.

you will gain 1000rpm which for around $2500 (turbo swap + purchase - selling of -10).

It'll be the best value you'll ever see on a bang for buck scale.

Perhaps wait till Piggaz posts his results and see for yourself before deciding?

[Griffin]

70mm pipes that merge to 80 mm with 80 mm exhaust from there on. They are HKS pipes, with TRUST dumps. Why do you ask mate?

[Griffin]

ok how about tuning -10s for atleast 25psi, how will that go?

[N1GTR]

Each motor and setup is different, so no one can accurately predict what result you will get from that change.

Try it and see.

[GTRsean]

And I thought -5's were lazy on a 2.6!!!!

Yep, only way to see what your current setup will do 'safely' is to put it on the dyno and test while monitoring vitals.

Then let us know how it goes.

[Piggaz]

This 1000-1200 RPM that you pick up although I KNOW it's true... But my head can't fathom how the car will feel!

[Beer Baron]

the turbos you want to switch to are HKS 2530s or Garret -5s. much better option even on the most finely balanced RB26 in the world.

[Griffin]

Im sticking with the -10s

[N1GTR]

Enjoy the lag!

[Luke_ENR34]

Iv'e also got the GTRS (actual HKS ones) i picked up brand new for around 3k so just gonna see how they go, i know they will be laggy on the stock 26 but hopefully with cams, e85, ARC twin entry front mount and a light car they will work alittle

[N1GTR]

On a stock 73.7mm rb26?

Wow, thats going to suck majorly. E85 and arc twin entry wont help either, but dont listen to me or Piggaz - we wouldn't know or have tried that and posted results on here.

[R31Nismoid]

Sometimes people just have to see for themselves...

Someone post Gav's graph just for a laugh...

[N1GTR]

No don't do that, it's time for the standard close topic post from you. Don't forget the "use the search button" line, that's my favorite part

[Marlin]

Lolzzzzz bitchy lot

But serial, Baron's right again.

On a 26, -10's, yeah no.
