I'm trying to source a supplier who can build a turbo to supply my needs. I would prefer a ball bearing turbo which rules out Turbotechnics. This is the email and posts I've sent to numerous turbo contacts.
Anyone here have any ideas?
Thanks

I'm trying to source a performance hybrid turbo for my 2.3T Saab. It has a Garrett T25 (CHRA 443854-55 TE1818F) as standard and did produce 220hp at 1.0bar boost pressure. I have additional items on the engine now and need a turbo which will spool up fast but also be able to supply up to 2.0 bar boost when required without running out of steam.
I've been in touch with 4 turbo specialists in the UK and have got 4 different specs on what I should buy! I'm confused!!

This is what I posted on a performance website....
I'm in the process of trying to get a ball bearing hybrid for my 2.3 Carlsson. One specialist says I need a GT 28 Series good for 320-360hp another says I need a T25-T28 with a .64 exh housing and a .42 or .6 or go to a 0.8 T250 compressor housing, another says I need a T28 with a .64 housing as fitted to 4x4 Cosworths.

Another US company told me this....
Looks like I have one more recommendation to confuse you with :-)
I would actually suggest a smaller T3/T4 hybrid. The reason being is twofold, one - even our largest T3 will only support about 325 HP at the flywheel which is a far cry from your 350+ goal. Two - I can't see a T2/28 series turbo producing that much HP. I haven't seen one yet.
As far as the exact turbo, I would suggest the T3/T4E hybrid with Super E50 compressor wheel & Stage II turbine wheel with a .63 A/R turbine housing ( T3 Flange ).


I'm running a gas flowed head, 3" JT exhaust, no cat, Aquamist running 50% methanol, modded airbox with JT filter, mbc plus minor other mods on this engine and am running about 1.6 bar but this might go up to 2.0 bar as I have a race engine built awaiting fitting thus want a turbo which will be able to supply 350+hp reliably.

Preferably the turbo will be a straight swap, but small mods to oil feed and return and waterpipes can be accepted.

Have you tried: http://www.universal-turbos.com/pturbos.htm ?

Turbo Dynamics do a couple that fit this criteria.For the GTiR they are called the MD214&MD196,not sure about the compatability with Saabs.Expect more than 350bhp on 2bar boost though.

You could try www.owendevelopments.co.uk. They might not be able to help, but a phone call can't hurt.

I just bought a hybrid turbo from them for my MR2. They've machined out a Toyota CT26 to allow a T4 compressor wheel, strengthened all the internals, ported and polished it and then trimmed the exhaust turbine by 8 degrees. MAN I can't wait to get this running

All the best.

Thank you Matt, have been in touch and they recommend a Garrett GT25R with roller bearings with a .64 A/R turbine housing which is supposed to be rated for 390bhp. I can upgrade the comp housing when I fit it on my tuned motor which will be able to cope with up to 440hp.
It'll fit straight on as it has a T25 exh flange but I will have to get an adapter plate to line up the exhaust pipe.
I'm still searching though and learning at the same time.

Try AET turbos http://www.aet-turbos.co.uk/

I know of a few unusual high power cars using their turbos so shouldn't think they'll have a problem sorting you out
