Garret Gt3040r 0.63 A/r Conversion?

[Nabil]

Hey guys need to upgrade my hairdryer....oh sorry my stock turbo on my rb25.....lol

Thinking of putting a gt3040r with a 0.63 rear housing so it can be more responsive. Searched it already but no luck.

Its a 600hp dual ball bearing turbo. Want to know how responsive its is and when full boost comes on?

Who ever has this info it would be most appreciated. Basically I want to increase my present 211.8rwkw to about to 260-270rwkw. HOWEVER, response and streetability is my first and foremost goal! Dont want a snail that has great peak power but poor low-mid range.

Any help would be great? I do not wish to hi flow coz its around the same for a new turbo these days.

Go the GT3071R then, a 3040 might be too big unless you've got cams pfc injectors, pump, z32 etc etc.

The 3071 is a straight swap. Well it is if you get the T3 turbine.

pfc injectors, pump, z32 etc etc.

all needed anyway

i have the HKS version of the 3040

291rwkw on 18psi with poncams

i have the 1.12 rear housing, so fairly laggy at full boost at 5000rpm

without cams you will still get boost about 4000 rpm-ish with that housing.. cant say for sure,

I'd step down to the GT3076R (HKS GT3037 56 trim) or the GT3071 as mentioned. The GT3040R is a mismatch turbo and will be too laggy for your power targets.

If you think you need 'em for the 71, your gonna need 'em in spades for the 40.

You are right though!!

The 71 will provide plenty flow for the .63 housing.

Personally I think the 76 or 82mm wheel will be a waste as the exh side won't be able to flow enough to make the most of the comp wheel.

CAn you elaborate on this GT3071R

What size ex. A/R should i use?

What is it rated at?

Do i need a custom dump? How much?

How much is this turbo cost?

Is anyone running this turbo on a RB25? If yes please state mods and power made.

PS: I will put a pfc in with the upgrade and run about a bar of boost. I will in the future place some bigger injectors and z32 afm (or maybe pfc-jetro)

Thank You In advance!!!

[Nabil]

Is there anyone who knows this info?

I just found the rating (its 500hp).

[Cubes]

Std injectors won't handle 1 bar of boost from a GT3071r.

I'd go one back again, 250-260rwkw is smack on the peak for the GCG Unit, and it gives insane response with great top end.

For the sake of having 250-260rwkw as opposed to 260-270rwkw (which can be attained by playing with dyno numbes if you need the sheet), i know what i'd choose for the RB25.

FOR F@#$%K SAKE!

Does anyone know the ANSWER to any of the above QUESTIONS???

Ahhhhhhhhhhhhh much better now....

[Cubes]

Do plod through the rb25 dyno thread....

There will be some one in there running a gt3071r.

I know of one but it was behind an auto and had an OP6 turbine housing machined up for it.

[Nabil]

I done that bro but had no luck.

Probably gonna start talking to myself soon.

try doing some research, you have been handed some info on a good choice.

price will depend on where you get it

custom dump pipe = YES - depends where you get it made

response - go for the 0.64
