as above ,what are the diferences in the two performance wise ,characteristics ect cheers

 

Same turbo 2 names....LOL

t35 is usually referred to as this from a 4x4 t3 modded to a t34 spec. as in a T34 with a .48 rear housing....

But essentially its the same turbo.

Just specify the .48 / .55 / .63

55 is the best one IMHO

 

cheers

 

t3/4 came on a std escort cossie, with .63 as std, but .48 and .55 are available


a t35 is a deisel turbo

 

THE TWO TURBO's A VERY DIFFERENT!

One is more suited for a YB setup and the other anything smaller.
The T34 blades are very different to T35 Blades i.e the air flow charateristics.

I use the T35 on a FWD car upto 300bhp over that a T34 would be better.

T34 has more lag than a T35 down to the shape of the Compressor blades and design housing.

 

Jano - how do you overcome the fact the T35 is designed for diesel application i.e not for the heat of a petrol car?

 

iirc he replaces every component with ones from another turbo...

...it's a bit like trigger's broom

 

quality

 

They are made from the same materials and have the same heat ratings as any other turbo made by the same manufactor.

So....you dont have to overcome anything! Apart from opening your eyes to other ways John.....

 

my eyes are always open to new things. Mine was a serious question. I thought the wheel was made of a different material, always willing to be corrected.

So a Standard T35 will just bolt on without any internal mods? Apart from obviously it being the wrong bolt pattern (as a T34 is for RST)

How does it flow compared with a T34?

 

I didnt say NEW! I said Different!

No the compressor wheels are made from the same material.

NO it wont!

Same amount of flow but at different times and bands in the rev range.

 

So what needs to be changed on it - i.e that isn't compatible?

Have you got the compressor maps for both?

 

how about the turbine wheels? the compressor wheels don't exactly have the hardest job, and there doesn't need to be a difference there for petrol or diesel.

 

I have graphs for Three cars that run these Turbo's we are talking about,

One is on a FRST 1900cvh 803's T34. He has 296bhp & 295lbft
He would make more power with a smaller Turbo and zorst Housing


One is a ERST 1600cvh T35-48a/r 803'2 & leaking valve seats 275bhp 265lbft

One is a FRST 1800zvh 803's T35-63a/r = 260bhp & 245lbft
He would also make more power with a smaller zorst housing

Some of the graphs can be found here

The Turbine wheels are the wrong size anyway, so we cant use them!

But yes you are correct in saying that these componets (Shaft) are different and will change depending on the fitment, temps, and size etc etc...

 

So what about the turbine wheel - is this changed?

 

Of course in a T35

you use the front end of the Turbo to rebuild it into a hybrid (if wanted) using :-

Maram (if wanted) Cut back (If wanted) L/H, Shaft with Step Adjusting oil seal

360 thrust bearing, oil thrower and seal.

New back plate and gasket/seal (If uses a seal as some dont)

New Compressor blades

New Compressor Housing

New journal housing cut for 360 (if wanted)

New Journal bearings (uprated if wanted)

New shrowd

New Criclips

New Bolts and Clamps

New oil return gasket

Left hand lock nut

 

thanks jano. So what wheel is it changed to? A t34?

 

Any T3 turbo shaft will be fine, but obviously if you want to run high boost you would be better off with an uprated shaft.

 

I meant the turbine wheel? or is that what you mean?

 

you have a Shaft which has a friction welded Turbine wheel attached to it (STD) which is the exhaust driven blades and the compressor blades which sit inside the compressor housing and is not attached to the shaft but is clamped down with a nut on to the shaft sometime have a lefthand thread on them to stop them undoing.

So yes a Shaft and Exhaust Turbine are the same thing really as they dont come apart unless you overspeed them

 

So how would you tell a T3/04 (ECos) and a T35 apart externally????????

I was also of the impresion they were one of the same

 

why would this be best ,what diference from a .48.63 (lag?)

 

I sense a stu essay moment approaching

 

Would be good As I say I was under the impression peeps just refered to the same turbo by both names

And as Im in the market for a new T3/04, think I best find out lol

 

Jano, you forgot to balance it

EsCos (large turbo model) std turbo was a T3/04B

EDITED: not for Damo - your post wasn't there when I replied

 

From what i was told at TT there is very little diff apart from they fit diff manifolds but im no expert

 

think he's holding out

 

They are not the same,

If you had both compressor blades on a table (Side view) the T34 blades are wide apart and not very high. The T35 blades are compact together These blades look more triangulated <sp (From the side) and are taller than the T34 type.

I will take a pic for you tomorrow

 

AAAh $hit i knew id forgot summin off the list

 

pics then please jano !!
