T25's How much boost can they run safely ?
My T34 is in need of a refurb and its got me thinking about doing something different.
I went out in Daryl Fletchers MkI Escort Camper Van a while back that Karl had mapped with a T3 on it and it went like a missile, much nicer than my laggy old T34 and it got me thinking about smaller turbos.
Plus I'm pumping so much cash into the Anglia stuff we are doing I aint got loads to spend on my cossie so I thought about a T25 and the Rouse type cars as they make bags and bags of torque and almost zero lag.
SO....
Whats the most boost they can run safely ?
Could I use one with my existing Green Injectors & 3 bar ?
Will my exhaust bolt up to it without any mods ?
Will my 500 Intercooler be ok with it ?

You just gotta love this forum... A post about shaving your nads gets hundreds of views and plenty replies from boys with bald sacks...
But I ask a 'technical' question and nuttin......
Surely someone with a small turbo escort must know how much boost they run with their Stage I conversion.
Or someone with a Rouse can give a bit more info on the conversion

What T25 is it?
There are many turbos that get referred to that way.
Its NOT boost that its going to be limited by though, it will survive a couple of bar probably, its the FLOW that is the issue.
Cossie will have it dropping off the right of the compressor map even at relatively mild boost.

how much boost you thinknig of running, im sure there was one or two in Retro Ford a while back, Anglia thrash i think it was, mind you you dont need alot of power in a car like that, a stage 1 is more than enough imo

You would need to get your ecu mapped to suit.

20psi sounds ace...
Can you do me an off the shelf chip for this Stu ?
Or do I need to come to blackpool... ?

I also know the chap who was quickest overall as he is the only person I've ever spoken to about Cossie'ing an Anglia who took my advice and went small turbo...
0-60 in 5 seconds dead is not to be sniffed at, especially as its on an auto box

Testing the future
would be lovely on a turbo like that with a good map i reckon 
a live mapped t34 with .63 exhaust housing is not all that laggy or unresponsive though - just too much power to realistically use in such a narrow and light car, so i think you are going about it the right way

Off the shelf no problem if you have someone check the AFR before you give it death to the limiter in top gear pal.

Errr sorry mate I think I havent explained myself properly.
Its for my 3 door.
All this talk of Anglias is because we have a project on to develop a kit to fit the 20v Toyota 4AGE engine into my Anglia van and thats where all my 'spare' money is going.
The T34 on my 3 door is in dire need of a re-build and I've been offered a very low mileage T28 cheap so I thought about using it as a stop gap.
But I always recommend anyone fitting a cossie motor into an Anglia to use the T25/T28 for the reasons you stated, narrow car with short wheel base.
