badtoy Posted March 18, 2002 Share Posted March 18, 2002 I would like to upgrade my stock twins with a set of upgraded stock turbos, does anyone in this group has a uk spec supra with upgraded stock twins or hybrid turbos? any real power or torque gain? at what range. here are the uk/nato/us specs of the stock turbos: Sequential Turbo'sCT12B(export) Turbine Size52mm/44mm (big/small end of same blade) Compressor Size58mm/39mm (big/small end of same blade) Turbine materialSteel Scroll area (mm^2)740 A/R ratio0.53 cheers Markus Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted March 18, 2002 Share Posted March 18, 2002 Gavin L will be along any minute now. He has these fitted to his UK spec and from sitting with him around Bentwaters, my first impression is that when they spool they felt a lot stronger all the way to gear change. Not so much of a noticeable transition between turbo no 1 and 2 as on BPU cars running std turbo's. Not sure if that is very clear. Quote Link to comment Share on other sites More sharing options...

Not so much of a noticeable transition between turbo no 1 and 2 as on BPU cars running std turbo's. Not sure if that is very clear. Unfortunately I don't have any of the technical info on my hybrids and until later in the year they won't have seen a dyno or drag strip. So hard data is a bit lacking. Power delivery is exactly the same as the stock turbo's only stronger as you would expect. On the occasion that Martin was in the car I was running at 0.85 bar however they are now running at 1.2bar which is quite a increase and pending tuning later in the year into the 1.4 - 1.6 bar range. My Supra went from stock to hybrids so I never really experienced a BPU Supra to make a good comparison. Stuart H and Eric had a quick blast in it a recently they seemed in impressed they might like to comment. regards............... Quote Link to comment Share on other sites More sharing options...
randy Posted March 19, 2002 Share Posted March 19, 2002 Gavin, Where did you get your turbos converted to Hybrids? How much did it cost you? and do we need to anything else performance wise if we are using hybrids? What is the max boost the hybrids can take? thanks!

My Turbo's were done by a guy in the UK called Leon Green. He can do a fit and supply or supply only arrangement, it does required rework of your own turbo's not a straight exchange. If you look at the details of my car under member 14 (www.mkivsupra.net/members) you will see what was done to the car, bear in mind I have a UK spec car with 550cc injectors. I understand that the turbo's are rated to 2bar but I am not likely to see that level of boost with the current configuration of my car.

badtoy Posted March 19, 2002 Author Share Posted March 19, 2002 Hi thanks a lot for all informations. Gavin, do you have an E-Mail adress of Leon Green or a website, I would like to contact him to verify the exactly costs. thanks Markus Quote Link to comment Share on other sites More sharing options...

Nic Posted March 19, 2002 Share Posted March 19, 2002 Hi Gavin Do you know roughly how much the hybrids and fitting costs were? Does anyone know of anywhere in the UK that could do exchange hybrids? cheers Quote Link to comment Share on other sites More sharing options...

Alex Posted March 19, 2002 Share Posted March 19, 2002 Gav, Out of interest what would have been the price difference to go for replacement turbo's instead of getting your re-worked? IE - if you had bought two smallish garrett turbo's which are a comparable size to the hybrids - how much more would that have cost you, do you know if this would have necessitated getting a new exhaust manifold?? Did you do any other research at the time?? Cheers Quote Link to comment Share on other sites More sharing options...
Eric Kasir Posted March 19, 2002 Share Posted March 19, 2002 Yep, I had a BPU Supra, and was definitely impressed with extra performance given by Gavins Hybrids, although that could have something to do with the fact that I was crammed into the back of the car 'cos Stu had to sit in the front 'cos he is too big and lardy for the back If it were me, I would go down the Leon route for upgrading to Hybrids, simply because he really does know what he is doing in this department. If I had of kept the Supra, it would have been my next mod. Eric Quote Link to comment Share on other sites More sharing options...

badtoy Posted March 20, 2002 Author Share Posted March 20, 2002 @all here is the anser I got from leon, thanks again for his e-mail adress Gavin. -------------------------------------------------------------------------------------- The Turbo's are reconditioned units, on exchange basis and as long as yours are rebuildable. I have three stages in Hybrid Turbo, pretty much mild to wild, all steel 360 deg thrusts etc, compressor wheels range from stock sizes to pretty much as big as you can get. Most common are the stage 2 and 3. Customers have described with the stage 2 its like jumping from a Ford Mondeo straight into a Supra!. STAGE 1 £1150 STAGE 2 £1350 STAGE 3 £1500 Regards Leon. ----------------------------------------------------------------------------------------- Quote Link to comment Share on other sites More sharing options...
randy Posted March 20, 2002 Share Posted March 20, 2002 I would appreciate it if you could give me leons e-mail also does he have a web page? Regarding the turbos-I would have to give him my turbos and he gives me the upgraded ones. Is that right? Also what sort of horsepower gain can we expect? STAGE-2 its like jumping from a Ford Mondeo straight into a Supra!:shocked: Will I feel that much of an improvement with the hybrid over stock turbos running BPU? 19psi?

THOR Racing Posted March 20, 2002 Share Posted March 20, 2002 My hybrids have the same effect at 14psi as my stock ones did at 18psi, making my 18psi nice :-) They were Leon modded ones (actually Leon doesn't do the turbo conversions as this is a engineering company that specialises in turbo refurbs) but he provides a complete service.

badtoy Posted March 20, 2002 Author Share Posted March 20, 2002 Pete, do you have a jap spec supra? or an uk spec supra? Quote Link to comment Share on other sites More sharing options...
Alex Posted March 20, 2002 Share Posted March 20, 2002 All, Please don't forget that the Jap fueling is likely to run lean on hybrids with anything more than 1 bar. Cheers Quote Link to comment Share on other sites More sharing options...

badtoy Posted March 20, 2002 Author Share Posted March 20, 2002 I just called up mr giles rose from turbotechnics Tel: +44 (0) 1604 705050.

What does it mean max out the ct12b? Also it would cost me 1300- right for the two turbos and I would need to send my old ones back to him. Also is it OK if my turbos are blown?

randy Posted March 20, 2002 Share Posted March 20, 2002 Pete, I assume this is the max psi available too you on 440cc injectors? Gavin, I woud need to cange over to 550cc injectors if I run up to 26psi right? Or do I require to go a bit bigger? Also what happens to the stock fuel map in our computer? I heard it is functional only upto about 19psi?Do we need to get a fuel computer and tune it? Quote Link to comment Share on other sites More sharing options...

Who knows, this question is about your car as well as the turbo's. I personally have not dynoed my car as yet and as far as I'm aware Pete hasn't either. Max out ...I would imagine that equates to the largest configuration deemed to be safe by Turbo Technics, probably around a stage III in Leon's books Old turbo's... yes this is exchange, you would need to send your turbos to them. I would be very suprised if anyone could buy in turbo's, rework them and sell them for a profit at £650.00 each. Blown turbo's...more than likely, assuming they aren't too far gone. You could probably get away with the "US guaranteed to blow your turbo's to f$%k mod", on the other hand you might not. Quote Link to comment Share on other sites More sharing options...
