Okay its Saab related but I'm not having much success and although I am picking up snippets of info here and there I though someone on this board must know someone who is an expert and could help! This is what I've been emailing about and am getting totally confused. 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 ). Turnotechnics said ' The problem you may have is a size issue, we have two ways you could go forward, either use one of our bespoke T3 turbine housings with ••••• a/r and a direct fitment T2 flange And either a T3 size front end or T35 front end,or the other way to go forward would be to go with a T35 unit as a whole the only problems with the second option is you would need to modify the manifold. The other problem with going on to a bespoke system is the size of the unit and the modifications you would need to make to the oil water and inlet and exhaust pipes.' 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 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. Can you supply me with something suitable with what spec and at what cost. Are there any turbo experts who can guide me to what I want/need etc. | ||

Just got back from dropping off my Yamaha turbo at a place near Sacramento,Seemed to know his stuff,been in business for a long time--Turbo Power out of Cameron Park.www.turbo-power.com or check with Motorhead over on the Hayabusa board,http://www.suzukihayabusa.org/phpbb/viewforum.php?f=20&sid=d5cd6a7d0d1cb06099a7c 88293f788ce Good luck. | ||

From my understanding Abbott Racing in the UK or SPG9 in the states are the two power specialists when it comes to Saab's, so I'd trust either of them. From my communications with SPG9 I think I would lean towards them since I think their less into getting your money than they are into beefing up your car. Thats just my impression. Good luck, btw I've got a '92 9KT, love it! | ||

Abbott Racing are expensive and their products are top quality - which is why Saab endorse and sell them. Mark is looking for something outside of Abbott's expertise. Strange as it may sound I'd suggest Mark talk to Richard Albans at TTS Performance. TTS Performance Engineering have a wealth of 4-stroke tuning knowledge. Richard Albans, founder of TTS, has over 27 years of dedicated 4-stroke tuning experience. Richard is renowned throughout the motorcyling world as a leading expert in 4-stroke tuning. Heading an ever expanding team of engineers, engine builders and mechanics, he has made TTS the premier tuning centre in the UK for Japanese motorcycles. TTS has it's own dyno facility, including the recently added car rolling road dyno specifically designed for hillclimb, sprint and autograss vehicles. Rocket | ||

I'm in discussion with Group9 Performance but they are so slow!! My turbo is smoking badly so need some positive movement on another turbo, might have to get a standard one to get me by though. Abbott's gear is overpriced, over rated and over here!!!! They farm out most of their work to subcontractors then treble the price! Rip off merchants, mind you if they sold square wheels their fathful followers would probably buy a few sets...... | ||

Hey Mark I've got my thinking cap on! I don't have a contact number but search out and try talking to Swiss company 'Hirsch' or 'Saab Performance by Hirsch'. I believe they make larger turbo's for their tuning kits. Hirsch are Saab approved too. Rocket | ||

Hirsch...I would need a lottery win to buy from them!! They are good but even more expensive than Abbott. I'm in talks with Group9 Performance on the east coast of the USA and they are speccing me one similar to a customer who has had good results with one made up for him. Thanks for everyones help though.... | ||
