hey guys, i posted up on the wanted section for a t3 turbo for a zetec turbo conversion im looking to do over the winter, however im not having much luck with a turbo for my budget at the moment, so i wanted to ask a bit of advice

basicially this is what i want to achieve

i want to convert my 2.0 blacktop to run with a turbo to produce 240 BHP. im picking this figure as i want to keep the engine internals standard (all i will be doing to the engine is fitting a decompression plate) im also going to be having a max boost of 8PSI, i believe the standard zetec internals will be able to handle this (please correct me if you think that is wrong).

obviously the turbo to go for is the Garrett t3, however these are quite hard to find for my budget, i would really like to find a turbo for under £100, as i trying to do the install on a tight budget, firstly there seem to be a few of these kind of "fake" looking turbos on ebay:

im guessing these are going to be cheap chinese rubbish and i should stay away?

what i really wanted to know what alternative turbos there are out there that i could use, and pick up a second hand one cheaply off ebay, ive seen quite a few GT17's from 2.0 SAABs but im not sure if these would be suitable, then again there is the k03 turbo from the 1.8T golfs,

at the end of the day i want a cheap turbo, (if i can get it cheap because it needs a rebuild then even better, im a mechanical fitter on a nuclear powerstation and often have to rebuild pumps on a slightly larger scale) that will give me the power that i want, any body got any ideas of suitable turbo candidates?

im not planning to do the install until the winter, but i cant get the exahust manifold or anything done without first having the turbo so i can work out where everything is going to go!

is there a particular reason for wanting a zetec turbo? just curious as you could probably buy a nissan 200sx engine and box for less than you could sell the zetec for! that would be sufficient power wise. or a saab turbo lump is dirt cheap and has huge potential. 350bhp plus, and im sure they mate to vauxhall rwd box

I have a brand new zetec fitted in my gbsc zero, on jenvey throttle bodies with an emerald ecu, I'm not looking for a major engine swap project, I would like to work with what I've got

Hello

I,m currently in the same boat although I have most of the parts other than a decompression plate.

From what i have researched standard internals are ok up to 250bhp.

The t3 apparently may be a slow to spool a T25 is better suited something from a 200sx although that said I am
going to try the turbo i have, its series 2 RST unit, although i believe its a hybrid of some sort.


Any way here is a link to a turbo in your budget.

Thanks I will keep an eye on that one, what's the max boost you can run with standard internals? Spool time isn't a great issue as I want to use the emerald ecu to control an electronic boost controller to give gear driven boost, as in no boost in 1st gear so that I can get off the line and then the boost coming in part way through 2nd and full boost in 3rd and 4th.... I think I can do that unless I have completley misunderstood the emerald ecu manual

I think Coozer had some bits for sale

As a guide 11-12 psi depending on what compression ratio you end up with, i have read some people up to 15psi
but a suspect the engine is stressed running this amount of boost.

I guess the mapper will govern boost level subject to any det.

Fair enough, haha time to bite the bullet and spend money on a turbo

I watched Tom drive up the road with this, it kept spinning the wheels as boost cut in

Regards Mark

you cant get cheaper injectors than the vxr astra ones which come with a rail and reg for £117 annd are 440cc

Got my injecters from scrappie of a 760 turbo volvo for 8 pounds.

Saab reds or the Volvo ones are ideal for a low power turbo , I meant that the vxr are a bargain compared to the green giant 440,s

Managed to get my hands on a Subaru impreza wrx td04 turbo last night for 50 quid, and it will easily give me the power I'm looking for at the correct boost. Once that arrives I can start modding the standard zetec exhaust manifold to take the turbo! Once that's done I need to manufacture some kind of plate and spacer so I can bolt my Nissan gtir plenum chamber on to the jenvey throttle bodies! So far I've spent 110 on two major components! My budget is looking good! Once I get the turbo it will be having a full strip, clean and rebuild with new seals, bearings and thrust ring.

You do not need a decomp plate - this is a bodge and is not required anyway upto 16PSI on 98RON.

For example the Mk1 focus RS used 9.5/1CR and 14PSI as stock.

The stock engine will take 250BHP all day without a problem.

You do need to be careful when mapping it, if you need anymore info please contact us.

Hi,

Yep - we have used stock CR all our zetec turbos without a problem. We are building a zetec now for a supercharge autograss car with 10/1 CR, this engine will run 20PSI and make 400+BHP (full race)

380cc injectors are fine for 250BHP (but dont be tempted to use old cosworth ones, these are poor) Bosch gen3 injectors are the way to go. Saab / Rover tomcat turbo injectors work well also.

We are in Shropshire, have a look at our website www.baileyperformance.co.uk

thats really interesting about the decompression plate, can you explain a bit further why it is not needed? most people seem to use it, im guessing by lowering the compression you decrease the point at which detonation occurs, so rather than lowering the compression if you use a higher octane fuel and having the timing mapped correctly again you will achieve the same result as a decomp plate? ie lower the point at which detonation occurs?

at the end of the day, i want a reliable and relatively unstressed engine. so 230-240 BHP is my target, and that will be more then plenty.
