You got any pics or more spec's about the turbo?
It will more than likely need alterations, as in rotating housings, new oil feed etc

That turbo won't fit on easy mate, its got the wrong exhaust housing to join up to the standard 5 elbow
If want an easy to fit turbo keep an eye out on here, some always come up for sale which have come off a 5

I've got one that needs a rebuild (285 quid to be done with a 360 thrust bearing) and another that works fine (is nearly new, only used for a short time and bought brand spankers) but has the odd whiff of white smoke on idle, so will need a rebuild in a few months I think.
With minimal work this turbo does fit on a 5...... But the only problem is the exhaust housing.
The exhaust housing is .49 but a round outlet like a cosworth, to make your life easy you can change it for a tomcat exhaust housing that will fit straight on. Or if you can weld use the sabb downpipe and weld it to the Reno one........by doing this you will get rid of the restrictive elbow.
This is a better turbo than a tomcat as the compressor wheel is bigger than a standard T25 but smaller than a T28 so it's a good middle ground.
I have fitted one to a car and know of two others being used for allot of time with no problems, like you hear about the tomcats.

well im looking for something that will push out 200bhp with minimal costs ive got a welder so thats not a prob just dont know much about turbo's
For anyone else looking at this turbo the best one to get is the one pictured with the alloy inlet pipe that bolts on with two bolts.
They latter changed it to a gt17 that will be too small.
I just rotated the cores and hacksawed the the alloy inlet pipe down, then put the filter straight onto it.
If my memory serves me well the compressor wheel exducer is 56mm.

Interesting bit of info there Miller, might be worth looking into these as the Tomcat ones are getting harder and harder to find in good condition
Yes mark they seam like a good turbo and are always found on the lpt "low pressure turbo" models so have not had a hard life.
As you can see the downpipe had the lambda sensor already fitted so would save some time for peope, it just after the turbo and the downpipe can be fitted at any angle.....

will the tomcat exhaust housing bolt straight on this turbo without any issues ?
Their is a difference between the internal heat shield in the turbo but the tomcat turbine housing still bolts straight on with no problems......you could also use a .64 from any other T25.
You are best to grab the alloy inlet if its the newer turbo also.
You could remove the compressor housing on both of them, if the wheel is the same size then you could use it as well.
Good turbos for very little money.

Sounds like
1. your oil pressure is low?
2. Your turbo oil feed pipe is blocked or partially blocked
3. You oil is dirty... ALWAYS NEW OIL and filter when you change a turbo!
4. Your over speeding your turbo (too much boost for its size).
You shouldn't go through that many turbos, I think Somthing is wrong!

oil pressure guage is reading 6 at all times now ? but was about 2 when warm think its not working now to be honest and it could do with oil change other than that im not to sure
6 at all times? Sounds like the gauge isn't working correctly. If it's the standard one, that's not unusual.

is there anyway of fixing it or do i need new clocks
is there anyway of fixing it or do i need new clocks
Best route is external mechanical oil pressure gauge:agree: just ignore the std gauge known to not give correct reading's anyway
