ok, thanks, i think its worthwhile rebuilding the turbo. Got mot, tax and insurance to pay out for in january, but after that i can get the block rebored, and start buying bits, cant wait!

I have a complete T3 turbo setup sitting in my garage doing nothing. Includes metro manifold and elbow (IIRC). Was going to stick it on ebay but you can have it for £80?

Inlet/carb/plenum are going for around £120 mark now. One I saw go for £180!! Crazy

All these threads about turbos are totally ruining my plans for my n/a engine lol
should of gone 1380 isntead of 1430 then it would of been easier to turbo in the future

[mini13]

shouldnt be a problem on a 1430,

you should be able to get 28cc in the head and get the pistons taken out to 15cc, that will get to to 8.5:1 compression.

Lol Bud get back your own account you just confusing people!

shhsss stu! ive got a turbo whatcha talking about?!

[samsfern]

one question i keep meaning to ask is whats better, and what are the pros and cons?

Lower compression ratio and higher boost

higher compression ratio and lower boost

[mini13]

Ideally you want the highest CR and lowest boost you can get away with for the required power and available fuel...

that probably dosen't help much!

[samsfern]

from what ive been reading, i was thinking of going for a c/r of 8.5:1 and running 15 psi boost, i dunno, what you reckon?

sounds ok to me, i run 20psi on 8.7:1

[mini13]

as above that will be ok,

[samsfern]

dont mean to keep dragging this on, but what final drive / wheel size are people using? Im thinking of a 3.105:1, which i think will be quite nice for motorway cruising.

Currently im running a 3.65, but have a very hot cam, i like that ratio, but id like something a little less revvy for motorway journeys, i occasionally do very long trips.

[Turbo Phil]

You'll find the torque of the Turbo will pull a tall diff fairly easily, so a 3.1 should be fine.
I personally run a 3.44 with 14's, because that was the tallest final drive that was available for my LSD. It's great for general driving, though a taller one would be a bit nicer on the motorway.

[samsfern]

one other thing, im getting the idea that ill be better off with a t2 turbo, how much would i be looking at spending on the mirage manifolds? Thanks for the advice so far

[Turbo Phil]

The Mirage kit is/was £350, I believe it's going up to £375 though ....

ooo cool, that means I'm going to be looking out for turbo parts on ebay now
