right then, the start of the turbo project
...
the parts list first(which i'll have to edit as i get pics and as i get the parts!

the turbo-T25 like off the LC


a recirculating dump valve-yes you do need a recirculating dump valve/wastegate when you're using an airflow sensor



a picture of a manifold the same as one i have coming (to chop up and make an adapter with for the omega manifold )

[ngrainqey]

right then..an update on parts...

i have so far..
a garret T25-here's another picture i can upload pointlessly to drool over!


the x25 exhaust manifold (which will end up chopped up and have a gaping hole drilled into it



the downpipe-yes...its going to get lots of abuse

and here's the bit i actually want off the saab downpipe

[kris9128]

sounds like a lot of hard work matey. good luck to ya  tho  

[Mr Skrunts]

Hows about this idea for a turbo conversion.

[Mr Skrunts]

Seems there are a few people trying out the turbo conversion at the rear.

How well will a turbo work at the rear though?  

Ive got 3 spare turbos kicking about at home!

I wouldnt have a clue.  From the bits I have read there is a gain in power but no where near the same as a manifold mounted system.

The one thing that was mentioned and talked about in detail was the ammount of heat , or rather less heat under the bonnet.

Would be interested in Marks DTM views and theory on rear mounted turbo conversions when he has time.

Yes, I would too.

I guess it will work, just not very well/efficiently . :-?

[ngrainqey]

i think the rear mounted turbo issues are more.... lots of lag! and less boost pressure (because of length of distance the compressed air has to travel but not sure about the second point!)

[nick v6]

not knowing much about turbo's
but dont there need oil pumping round them to kep them cool
how do they go about thet wen the turbo is at the rear

i bet it sounds nice haveing a turbo right at the back

i doubt it sounds any different wether on the manifold or further down the exhaust pipe
and yes they need an oil feed but its more about the bearings than keeping it cool, some have water cooled cores(possibly all do but iv not seen everysingle turbo unit so cant say)

[nick v6]

i wouldn't know where to start with fitting a turbo weather at the rear or on the manifold
be nice to give it a go

lol from what iv had to buy so far i think it's going to be rather horrible!
it'd be alot easier if you managed to get the saab 3.0 manifold with turbo as part of the manifold, makes it alot easier than what im doing

[nick v6]

are you putting twin turbos on your v6
will it affect the pressure in the engine resulting in blowing the head gasket

no just a single one to begin with.
aslong as you dont have too much boost pressure then the gaskets are fine
