Been offered a T34 and thought it would be a laugh to try it, do they bolt straight on or what do I need to do to make it fit?

depending on exhaust housing, get a cosworth type downpipe if on a cosworth housing.
compressor inlet is bigger IIRC.
otherwise direct.
will be laggier though...

Just used the magical search function and yeah need to cut and shut a cossie downpipe into my own so as to retain the cossie turbine housing which of course flows better than an RST one too.
I know it's going to be laggy! But it will flow for 300bhp and it's cheap! lol

you cant have a t34 with rs turbo exhaust housing, swap thebits from your t3 on to it,

Karlos G

iTrader: (4)

I ment the elbow not turbine housing sorry! lol
What bits mate?

crazycage

dont do it karlos ,fit a stg3 t3 . you wont like the t34

I'm with crazy cage, 55/.48 will be perfect for you

With the right spec it will make 300 mine made a smidge over but I run 280 ish in the car as its plenty for round my way

I'll show you a dyno sheet of mine if you like

Fair play fella's! lol
It was just offered to me so thought I'd try it but TBH having to fuck about making a downpipe etc is a bit too much hassle if it's really that bad.

I've got a stock one to fit today just to get me running again, so will keep an eye out for a bargain .48/55 or save my pennies up for a GT2560R.

The cosworth T34 is a little laggy on the cvh. The Iveco daily T35 is much better for this use and has less lag than the T34 and flows better than the 4x4 T3 with .48 housing.

The T35 does exist and not to be confused with the T34.

You can get a T34 with a .48 back housing to spool by 3500rpm on a 16 CVH. Depends how badly you hat lag but that seemed pretty acceptable wit the engines willing to rev from there all the way round to 6800rpm.

My GT28 isn't in properly until it's over 4k but the mapping is far from finished.

Full boost at 3500 daz? My t3 isn't that good!

my T34-48 dont seem too bad considering

xr2wishy

iTrader: (2)

cosworth 4wd turbo?
60trim on a 0.48 housing, will push well and used the same on my former zvh.
cheap power upgrade, boost came on at 2500rpm and full boost by 3200rpm, on a 1.8 zvh of course.

DazC

It was probably around 3700-3800 by the time it hit full boost to be honest Jim, but that was 26psi on a Cossie T34 with a .48 back end. By 3500 it had a bar of boost.

Karlos G

This talk of when they make boost is a bit vague and can't really be compared as it will depend on many many things... What manifolds you have, head work, cam, cam timing, mapping, what gear your in, what your ratio's are, what size wheels you run, how much weight your carrying and if the road is flat/incline/decline etc..
My gears for example are really really close (top out at 125mph) so i get through the rev's really fast leaving less time for the turbo to spool giving the illusion of a laggy turbo.
When I ran my old box which was really really long (theoretical top speed of 188mph)with 17" wheels it was the exact opposite.

J1mbo

That's identical I would say to mine

Is that a direct replacement for the T3 Jano or are any mods required (2.1 ZVH).

Versus_Creations

iTrader: (1)

It looks the same as the T34 without the acuator bracket built in.

Direct fit with either a YB exhaust housing or a cvh Housing.

Cheers Jano!

my box only hits 130mph, when i built my engine and took it out it has 1986 stamped on it ! so somewhere down the line someone has put a different box in, maybe from a 1.1 or something like that, 1st gear comes and goes so quickly, no even enuff time for a proper spool up

very wierd IMO

wilky

iTrader: (1)

you need the 5 bolt turbine housing ,that will bolt to your elbow,if you on a stage 3 t3 your turbine should be a .48 and bolt too the t34

1900 cvh and zvh will work fine on t34 with a .48 turbne my mate run.63 on turbine 1900 cvh 1 bar works fine quick box 130 tops

2000cc cossy standard had a t34 with a .63 housing and was quick enough
so a zvh will have no problem

DazC

iTrader: (1)

Very true.

I don't think my engine loads up enough to spool the turbo properly in the lower gears.

Cossie Sean

yeh get a cossie T34, and a hammer, adjust radiator, replace broken rad, replace T34 with stg3 T28 or t3, get a propper map done, smile

wilky

get a t34 comp wheel machined in to a t 3 comp housing

Versus_Creations

iTrader: (1)

wilky if you do that the act will be massively higher due to the smaller size of the compressor housing. You should not use or sings that have been machined out for this reason.

Karlos G

iTrader: (4)

I think for me it's either going to be a stage 3 T3 or a GT2560R, I really want to go GT but cost is a big factor right now so might have to be sensible and stay T3

wilky

iTrader: (1)

yes i have done this a few time not had a problem ,will the t34 run cooler at the same boost as a 4x4 comp wheel its more efficient on its map ,running more boost over 24 you will run hotter

i could be wrong but i have done it when room was a problem and it worked ok [think it was on a 4x4 v6]

kermitt

What is the difference and is it a straight swap onto an RST?
