HELP! Turbo size?

[TWiSDeD]

Hi Team,

 

I’m picking a new turbo set for my GTR, which will run E85.

 

So far, I’m so confused.

 

I want near instant throttle response & hopefully 330 AWKW.

 

Assume, full exhaust, turbo back, intake, cam gears, powerFC, E85 setup.

 

I’m being told so many mixed things.

 

RACEPACE tell me 320 tops on their special turbo.

 

I’m hearing Dash -7 too laggy but power 350...

 

Then I hear that I need 34 N1’s for 330, but then that they’re not the same as Dash 7’s, they’re more like Dash -9!

 

What the f**k.

 

Where do they all sit ?

Oh & im told -7’s are differ to N1’s 34 ... by Racepace ...! But Chasers tell me they’re the same I’m so confused

Hi.

I have upgrade the top end of the car and producing approx 385 age on E85.

The following mods I made on the car were?

Existing mods:

3.5 inch exhaust plus sports cat
Air intake
Boost controller

New mods to the above:
-9's
Dump pipes
Cams
Cam shaft
Heltech ECU
1150 BOSCH injectors

Depending on what you want to use the car for, there will be lag in the turbos.
Hence you need to make othe mods to ensure less lag.

If I had the time again -5's better for the track.

But having 385 on E85 and 315 on 98 is amazing power. You will never use that power unless you are at the track.

Everyone has an opinion about turbos unless you have installed them in the car people go off hear say. Dash -7 or dash -9's is sufficient for the road.

Firstly what is your budget for the upgrades including the tune?
What ecu will you use?
Are you planning just 98, E85 or both?
Top end only or both? Etc.
