What turbo to use?

[volvo]

Im a rookie when it comes to the purchase of a turbo,(or any thing car related, but very willing to learn)
you all seem extremely bright, so i was wondering if any one has turbo' d a
1985 2.6 litre mitsa sigma, tell me what turbo to get (power, without a blown engine), and would i need a custom manifold, and all the other problems and solutions with this instalation.
and also what size intercooler, cheers

(sorry it isnt strickly toyota related )

[Jorrs]

man could u seriously be bothered ?
sounds expensive, and hardly worth the bother, buy a GSR motor or somethin will be better in the end

[urantia]

ah the astra oilburner engine?

Hmm i reckon you'll end up with a blown engine if you turbo it
You'd need to do alot for it to handle a turbo for any decent amount of time. Lower compression pistons, oil lines for the turbo, custom manifold to fit the turbo.
Its a carb motor like i am thinking of? or more upto date EFI?

mmm i'd just put that idea to bed and buy a turbo toyota to begin with for cheaper.

Well its all i got , mum turns up with it, i suppose it gives me a year to save for a sprinter with my new job , (if there are any left )
so i figured might as well clean it up a little preformace wise. only want a medium turbo and
a cooler, its kinda a waste of time, but ive never even sat in a turbo car , so this way i could

the engine could take it, driven buy old ladie, its an emmac shit box

120 thousand gen K's, any suggestions poeple

there is a VR-4 2.0L Twin Cam you can get and its efi and you run a nice safe 12 psi on it with out intercoolering it

[volvo]

urant you are right
aww the dream is over

all that stuff with the pistons would cost more than the cars worth to do

thank you, and whats an EFI ?

[volvo]

o WAIT STUPID QUESTION ITS electronic fuel injection ,

when i get my sprinter, id like to do a famous, 4agze conversion does this require me to get EFI on it, or does that come stock?

[urantia]

That comes stock. All ready to roll for supercharger goodness. You won't look back compared to the stinkma. (sorry the sigma wern't that bad, i still got one kicking around, burns the oil but seems to keep going)

[whatthe?]

Taken from sigmaturbo.com;

"Under the bonnet the Sigma Turbo used the 2.0 litre, SOHC, Astron 4G52 four cylinder equipped with a completely new intake manifold and a Garrett Air Research T03 turbocharger sucking through a Zenith CD 175 carburettor.

Compression was reduced to 7.8:1 with boost running at around 8lb. This increased power from 64.4kW to 116.0kW despite a lack of intercooling or water injection. Driving through a standard 5-speed Borg Warner manual transmission the Sigma Turbo covered the quarter mile in 16.8 seconds and ran to a top speed in excess of 200km/h.

By current standards 116kW and 16.8 secs may not sound like much, but back in 1981 a Holden 308 V8 offered only 10kW more power, while any car that could manage a sub-17 second quarter mile was considered quick. "


I'd say trying to get your hands on the stock parts from one of these would be probably the cheapest route to getting a little more out of your car

can and has been done.
