GT1752 turbo?
rich201283 - 19/5/10 at 08:45 PM

Does anyone think a Garret GT1752 would be any good on a zetec and would it mount to a rs turbo exhaust manifold?

isnt that a little small?

Not sure - They tend to fit them on the saabs

That's like really small

I'd do the math as http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech103.html recommends

I'm pretty sure you'll be on the limits of the turbo though, even to develop 180hp.

Edit, like tom's and my 2l SR20DET uses a T25 turbo for 205bhp, so that's already a lot bigger.

weve just fitted the standard Escort rs turbo to a 2 litre zetec, and will be hoping for around 270 brake once dave walker has mapped it. It was running around 180 brake on the 1.6 lump with a chipped ecu.

We got it fired up today started first time, not bad for a completely fresh build. the car looks mint as well. So beware of a white series 2 RS Turbo in a village near you

Does anyone know what sort of power i would get with this turbo on a 2.0 zetec,

you would be better with a garrett GT2052 for modest power. Watch you dont get a diesel variable geometry one as it wont stand the heat.

TBH though id be going for a Td04-15g from a volvo t5 which will do 300bhp and 270 all day long. (about £50 on ebay when they come up)

Mine is a T28

Only to the Light Pressure Turbo (LPT) engines that only run a few PSI of boost. It's just too small for any useful performance on a 2.0L engine.

with respect that's rubbish - it's not a big problem to get 260bhp out of a 2.0 lpt Saab with a factory standard T17 turbo. It's only the ecu map that makes a lpt Saab a lpt Saab - change the map and.......

While I have seen them making 260bhp there were a number of different garrett and mitsi turbos fitted to the saab turbo engine and power is dependant on which one you have.

Also, while I agree the map is what controls the low boost pressure, and that a remap will improve them a lot, the lpt models in general came with a smaller turbo than the hpt models and hence will not make the same power if both are remapped.

regardless, its a bleeping pointless size of turbo to try and use unless it happens to be bolted to your engine anyway. There are a number of other much better choices for a 2l turbo.

I doubt that a GT17 is capable of that kind of power; it would be running way off the efficiency map so charge temps would be very high. Have a look around the web, this turbo is used for all sorts of small engine turbo conversions e.g. BMC/Rover A series, and Honda B and D series, and the consensus is that the turbo is good for about 200bhp, possibly up to 230bhp but you'd be well down on efficiency.

Don't have to look round the web - had one, done it, as have a lot of other people . I now have a 2.0 litre Saab 95 with a B205 engine and a TD04 Aero spec turbo, stage 2 ecu etc etc on it and to be honest, although ultimately quicker it's actually no more fun most of the time than the stage 1 ecu with the smaller turbo that still kicked out 225bhp and 300+ lb/ft torque...... how much power do you want!? lol
