Shall i put i cossie T3 on my S2 1.8zvh i know ill need a new down pipe but is there any reasons why not to? Like Pro`s & Con`s?

 

i think a standard rs turbo exhaust housing will bolt on a cos t3. im certain i read somewhere they flow more air iirc.

 

Well they are different but i will have to get a custom downpipe made (i assume they are abt £80?)
RST is 45 trim compressor A/R .42, 0.36 5 stud elbowed turbine housing

2wd cos is 55 trim compressor A/R .42, 0.48 3 stud non elbowed turbine housing

 

if the exhaust wheel is the same you can just put the exhaust housing of rs turbo onto cos turbo and use rs turbo downpipe

 

Are they the same? Will having a bigger exhaust housing be better in any way? (if i stick with the cossie one?)

 

yes

i put a rst ex hosuing straight onto a cossie t3 on my cabby

 

Seen many Cosworth turbo's on ERST's using the ERST exhaust housing - get it done

 

Ill do that then

 

So what would i need to change???

 

just take the cossie ex housing off and fit an rs turbo, may need to undo the compressor and twist the core and compressor housing to match up with your pipes etc, but that sit lol

 

using the cossie t3 compressor would turn it into a stage 2 rs turbo hybrid

if you use the cossie .48 exhaust housing also it would be a stage 3 hybrid if not better

 

I have just got a downpipe

 

That was quick

I wouldnt have had time to go to the local spar in that time

 

Things are all coming together nicely now Few months and it ill be on the road (Hurray!)
