Do a search from what I posted about my turbo within the last week or so.
I've just got a stage 1 hybrid from Turbo Dynamics, cost me £900 and the turbo dynamics spec is
"STAGE 1 - Retail Price - £900.00
MD61 Special Turbo Dynamics designed high flow six blade compressor wheel, (45mm inducer) with re-profiled compressor housing, 360 degree thrust bearing, twin turbine seal modification for improved oil sealing, new strengthened actuator bracket with stainless steel heat shield to take bolt-on, bolt-off canister, 12 – 14p.s.i. adjustable wastegate actuator, T.H.W.A. fitted with new tighter tolerance wastegate bush and new style arm & valve assembly, shims and tig welded crank assembly."
The guy said this is good for 300-310bhp, and the stages up start to get laggy.
I sent mine for recon, but they wanted £807 to fix it, as it needed a new exhaust housing and various other bits, so I paid the extra £90 to get the hybrid, which is still based on my original unit.
I've never heard of anyone needing a basic recon on these, its always more.
I rang a few other places for prices before I went ahead, and none of them seemed as professional as TD, but were all a bit cheaper by approx £100, but were also very vauge (sp?) about what their hybrids actually were. I'd also had a couple of recommendations for TD, and heard a lot of bad things about the turbo recon market in general, so decided to bite the bullet and pay the extra. For the price I probably could have imported a big turbo and had a fancy manifold made to suit, but the rest of my spec wouldn't match it and i cant afford to bring up to suit the turbo.
Edit: The price for the hybrid is £900 + vat, but I said that was out of my budget so he knocked 15% off, I also got them to give me standard actuator back, so barter with them!
