Anyone Have Any 1st Hand Experience With T70 Turbo

[r33cruiser]

hi guys, im on a budget = =casual worker

i am considering a t70 turbo.

i have heard both good and bad things. i know of about 50 ppl with them with no probs

have any of you actually used one

i will only be boosting 10-15psi, nothing extreme.

specs:

Front Cover A/R .7

Front wheel trim 64.5mm

Rear Cover A/R .82 t3 flange

Rear wheel trim 60.5mm

yeap - they are big, laggy, and a waste of time putting one on a Standard engine running 10-15psi.

15psi out of one of these things is enough to push a standard engine to blow actually. Proceed with caution.

What brand is it? Garrett?

[r33cruiser]

yea garret,

cheers for your response mate.

then would it be better to get something with an a/r of .60. eg a t66?

but im after 1st hand experience, not inuendo.

LoL, AR has nothing to do with the naming convention of the turbo. A T04z rear turbine housing for instance, comes in AR's of .70, .84, 1.00, 1.15, 1.32. The AR is the ratio of the cross sectional area of the turbine nozzle : distance from the centerline of that area to the centre of the turbine wheel.

IE: You can get a .70 AR capable of flowing 200hp, you can get a .70 AR capable of flowing 900hp

Your best bets to learn the limits of various stock bits of peices you have. injectors, pump etc etc, and then size a turbo that will be useful to you, in that power window. High flows are popular.

This LINK will help show you what you can do, with what parts

Thanks

What motor is it going on? RB25?

Whats your planned mods/current mods you want to run with this turbo?

Need more info man

Its kind of like me saying eg. "I want to run a t70, what do you reckon?" and thats it.

If hes on a budget, hes prolly not keen on spending whats required to support a T70. Theres a lot of negatives running a large frame turbo on a stock engine at low boost.... laaag.

cheers, guys, i might just go for a smaller to4 option, dont want to blow it up.

as for the semantics, asume i have all supporting mods, but stock internals

Turbo's dont blow motors, the amount of air they move with insufficient fueling does.

If you have the pump, injectors, spark, and way of controlling it all, then you'll be ok, its then up to you how much boost you run on the stock motor.

cheers mate, yea i have 550cc'ers, 040 pump, and jjr coils and iridium plugs.

im just a bit worried, as mafia said, i wouldnt want to go past 15psi. and lag, heard, theres nothin till about 5k.

so i will go a slightly smaller t04b turbo instead.

thx for all ur comments
