also...

who do i talk to about manifolds/adapters, etc?

Sorry man.... you need to put down way more information that what you have.

What engine?
What amount of boost?
What amount of maximum power?
Pump gas? (if so what octane)
Automatic or manual tranny?
Which car?

i thought evryone'd know that by now...

Daewoo Lanos
1349 cc 8v
boost: around 5 psi (keeping it safe for stock internals)
Manual transmission
Petrol/gas: pump, super-unleaded instead of normal unleaded (to keep it safe) not 100% sure on octane rating - but higher than average.
maximum power: not too worried about that yet.

this isnt deffinite yet, to be honest, im just keeping my options open seeing as i have a bit of extra cash. (ive still got supercharging at the back of my mind aswell - or even a NA beast)

'Pump gas' In the uk is 95/96 ron. Super unleaded is 97/98 ron. If that helps any.

Ps. I'd go for a turbo/supercharger running 5 psi over an N/A beast any day, you can still drive them kinda sensibly and economically when not on boost, N/A tuned cars, most on carbs, DRINK petrol flat out.

Well..... that's not an easy question I guess...... 1.3L 8V...... well I would say a T25 would be ok.... probalby not too much lag... hard to say.

The T2 is most likely smaller and should be decent..... with the internal wastegates (T2, T25) you have to watch for cracks in the exhaust housing

The T2 picture doesn't show any cracking.... but the T25 is at an angle where you can't see the inside of the housing.

For the price..... and what you want.... I'd go for the T2.... it will spool up faster and be very responsive to throttle.

ok, next question... lol

what about the manifold/adapter? will this have to be custom/specially made for the car or is there someone out there who already makes these?

A while back someone on here was selling a turbo kit for the 1.5L SOHC..... and I'm pretty sure that is the same bolt pattern as the 1.3L SOHC

It's possible to make an adaptor to go onto your stock manifold but it ends up putting the turbo very low, so I question whether there is enough height to allow for proper oil drainage from the turbo ( turbo must be higher than the level of the oil inside the oilpan or it will not drain )

Having a custom turbo header manufacturered in the UK would probably be very expensive.

Some guys who have used a low lying turbo end up creating a catch can for the oil from the turbo and then they use a oil sump pump to take the oil from the catch tank back into the oil pan.

If someone came up with a kit that included an exhaust to T25 or exhaust to T3 adapter and a powered sump system it would make turbocharging our engines fairly easy.

Here are some examples of electric oil scavange pumps..... not exactly cheap.... but I'm sure there are better deals to be had from non automotive applicaitions.

I often wonder if an electric fuel pump would work.... the fluid temperature might be an issue.... but I have to think they would still be able to push oil through despite the difference in viscosity.

Hmmm.... I wonder if it would be possible to go from the turbo oil drain into a low lying oil cooler then into a catch tank and then to the pump..... then the oil would be significantly cooler (when driving)

I guess it wouldn't help much at idle..... but there must me pumps out there that are designed for higher temperature (perhaps something designed for cooking oil )

well, thanks for all the input, PB, will keep it in mind or refer back to it in future.
will have to put boost ideas aside for a while again, cos that bit of free cash was spent on springs and an alarm system.

considering what you said about the height of the turbo above/below the oil pan it'll probly be better to just use a turbo manifold instead of an adapter, so i'll be keeping a look out for shops or metal workers near by that could possibly do it.
and... would i be correct in thinking that an existing turbo manifold from another car could be modified to fit a daewoo lump? ie: there are lots of turbo manifolds for all kinds of civic engines...maybe its just wishful thinking, but you never know.

Yes.... you could use a Honda turbo manifold and modify it.... might be a bit of a pain.... hard to say.

Hi guys,

Im still lurking these pages.
http://www.daewootech.com/forum/viewtopic.php?t=2755

The TD04 mounted nicely under the stock manifold with an adaptor. Even kept the A/C.
The oil return only ran the tiniest bit uphill, but i never had a problem with it.

I'd go for the T25. You'll feel the T2 will probably choke the top end a bit.
