Which do you think I would be better getting? Have a 2.1 zvh xe pistons ported and flowed head with cv36 cam superchips ecus running on mfi aiming for around 220-240bhp if possible. Looking at a stage 3 t3 or a standard t34 got around 250-300 to spend ideally.

bezo

i was going suggest a GT28 or a GT30-72, but if youve only got £300 to spend that kinda rules out those

t34 would be a good choice.

hi if your running the ke jet still id go for a stg3 t3 second hand 2wd cossie spec if u can find one for that .possible thoe

What is the BHP at the mo.

no matter what turbo you get mate you will need at least a fifth injector to push over 220bhp safely ... so i would go for a stage3 t3 and aim for 220bhp.... or if you are looking for future mods then a t34 but remember you will need to fabricate a down pipe to run it....

You need a cosworth 4x4 compressor wheel, 4x4 compressor housing, 360 bearing kit, step adjusting exhuast seal then balanced to 120,000 rpm. Call it what stage you like but thats the best suited to your engine spec on MFi with std rods and fueling.

Just to add that a T34 will be the worst to choose.

Main reasons are due to the size of the bottom end and the fact that a 1600cvh runs out of fuel before it is restricted by the size of the bottom end, so the extra CC makes it run out of fuel with less boost than a std 1600.

Next is that the fuel required for more cc and more boost can not be reached with MFi without bodging some sort of extra injector etc. In this day and age we have all moved away from that idea (which i never used in the first place) and replaced it with EFi management systems that can flow more fuel if required.

Last is the use of a T34 would need at last 20psi to make the most out of it as it will make you have some more lagtime over a smaller 2wd or 4x4 turbo. If your going to run less than this then a smaller more suited turbo would be better.

MFi cannot run 20psi + safe so why fit a turbo that would not be running optimum is pointless.

The above is from experiance not just random hear say and net waffle.

So when does a 1600 run out of puff.Has anyone hit the limit? just wondering.as you made some good points in that reply .

i run a cossie 4wd turbo, no 360 degree bearings or owt, but a 0.48 cossie housing and modified downpipe.
i have a 1,8zvh with megasquirt MS2 v3.0 running things and siemens deka 63Lb injectors.
i start making boost just over 2000rpm, full boost at 3100rpm limited to 22psi due to map sensor and lack of bravery for more.

i've thought of going for T34, but no real gains for me, no better ve efficiency and no real gains on boost, just more lag due to T4 compressor wheel and housing.

A T34 does not have any T4 parts!

Deffo not a T4 comp wheel or housing! Have you seen these in comparison ?

A Std 1600 CVH with 4x4 Turbo and cam will run out of puff at about 240bhp on a decent management system. After that you need more headwork.

t4 turbo bearing housing and bearing thrust bearing and exhaust housing all fit from t3 to4bt34] t04e

you can change all parts over no problem there loads of different comp wheel's and turbines from standardt3 to stage1 stage 2 stage 3 then the p,q trim turbine shaft[all turbine shaft sizes]

t34 with the .48 turbine work's well but there is a bit more lag

xr2wishy

iTrader: (2)

so what exactly is a T34 then?
i just assumed it's be a hybrid of t4 and t3 parts.
since they use the same bearings and all that.

wilky

iTrader: (1)

t34 is a t04b [its back plate and comp housing size]
t4 cossy is a t04e bigger comp housing and back plate all fit same shaft and center bodys
theres 3 main comp housings sizes .50 ,.60,.70 [cossy t4]

to be fair you don't have to jump from a t34 to the t4 you can bore hosing and put bigger wheels in mine fave at the mo is a .48 turbine with stage 3 t3 shaft work's well
fast spool smaller turbine keeps torque good and bigg wheel passes a lot of air
plus i bore t34 for bigger comp wheel's again faster spool up

turbos only good on 2 liter on around 400+bhp

my turbo i'am using is a hx35 with a hybrid turbine which i machined my self for faster spool up these can run 3 bar of boost lol

jano whats the best turbo for my car please...

1600cvh woszner low comp pistons and pec rods thats been fully balanced ect...
stage3 big valve head .... its got a piper cam at the moment but im getting a phase4 newman with genuine ford gaskets and arp's throughtout...
field motorsport inlet with green injectors and fully ported and matched to the head....
autospecialists manifold...
airtech front mount and rad and a stage3 t3
its on gotech mfi aswel

Cheers for the info dude

zvh

my 2.1 zvh with a fith injector run 286bhp on a stg 3 t3 with plenty of fuel safely.
and 264bhp without a 5th injector ,there are mods u can do to the metering head to produce more fuel

coswurv

iTrader: (8)

What mods are you able to do ?

rsmark86

iTrader: (3)

realy i dont see the point in a fifth injector for an rs turbo unless you pay like £150 for it as you can buy a gotech mini x kit for a bit over £400 and it took me 20 mins to find where all the wires go and about another 10 mins to tidy it up .....

now just stripping out all the old mfi wiring thats not needed....

Thanks for the replies guys much appreciated got the oppurtunity of a stage 3 t3 but unsure as to what housing it is i.e 36 or 48 there is no markings on it???
Jano do you sell the turbine housings?

rsmark86

iTrader: (3)

ive got a .48

drsrst2zvh

For sale or are you just stating that you have one?

I wasnt talking about cores or bearings as they are all the same other than being water cooled or not and ball bearing or floating bearing etc.


The T34 and T4 compressor housing, compressor wheel and back plate are different and can not be mixed matched.

The exhaust housing is also different, obviously. As one turbo uses a std size T3 shaft and the other a T4 shaft.

A T4 shaft will not fit into a T3 housing that the T34 uses. Either housing cosworth setup or escort rs or any other.

You can mod the T4 shaft by machining it down to fit into a T3 housing. Waste of a T4 shaft tho.

Next is that a T4 compressor wheel will not fit a T3 shaft so again you cant use bits of one and another.






Im not a trader on this site so cant offer any prices or quotes for work etc, just offer advise and help for those who asked for prices.

t4 comp wheel will fit t3 shaft both use 1/4 inch bore mate
also i bore t3 turbine to take the bigger shaft better hybrid
http://www.precisionturbo.net/small-...bochargers.php


have a look you havev loads of shafts mate
have any hybrid you want housing combo just a bit of machining

if you want too put a t4 comp housing back plate and wheel on to you t3 you can
all i'am saying is you can interchange all the part from mini t3 to a t4 [t04e]
so the range is massive

wilky machining parts to fit is not what i had in mind. Yes obviously if you machine parts to get them to fit then anything is possible. But out the box the parts are not compatible.

A T4 comp wheel will not fit a T3 shaft and assemble with a T4 back plate as the comp wheel is too high and requires machining, you would require a T4 shaft machined down to fit a T3 housing which is a waste of a T4 shaft like i said previously.
