jay200bhp Posted November 9, 2014 Share Posted November 9, 2014 Right gents ,just thinking aloud to be honest .. My engine at the moment has BC rods.Mahle pistons,arp throughout and runs a greddy exhaust manifold and wastegate.I have a divided turbo its a t4 flanged precision t6765.... If i were to change this for a smaller more responsive turbo... I.e a setup for savage savage acceleration... What size would you reccomend? Wouldnt be looking to change manifolds etc so bolt on would be good.Also my current t6765 has done less than 2000 miles and is perfect ehat sort of money do they fetch second hand?

JamieP Posted November 9, 2014 Share Posted November 9, 2014 GEN 2 6266, Jim has just done that very change (6765 to 6266) and loves it. Quote Link to comment Share on other sites More sharing options...
jay200bhp Posted November 9, 2014 Author Share Posted November 9, 2014 Cheers bigman.what sort of power comparisons are they? Also costings jamie? Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted November 9, 2014 Share Posted November 9, 2014 Could also go down the route of the gen2 6466; still benefits from the new tech, fast spool and up to 900bhp. That's the one I'm looking at Quote Link to comment Share on other sites More sharing options...

JamieP Posted November 9, 2014 Share Posted November 9, 2014 Depends what power you want. People have done over 800rwhp on the 6266, but that will be race fuel and mega high boost. Dean has a fair point, if I had a built engine I'd be running a 6466 now. I'm not sure on prices, I got mine as part of a full Turbokit. Jim is SupersizeJim on the forum.

Luxluc Posted November 9, 2014 Share Posted November 9, 2014 What power are you looking at mate? Quote Link to comment Share on other sites More sharing options...
jay200bhp Posted November 9, 2014 Author Share Posted November 9, 2014 im not really a numbers fella luc ,but I guess am I right the car will be around 720 on 1.9 bar with the 6765..... But if it were lower it wouldn't bother me to much .... If it felt right on the road. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted November 10, 2014 Share Posted November 10, 2014 The 6266 would be my choice then. In combination with ethanol, you would make similar power than your current 6765, but a lot more torque. Quote Link to comment Share on other sites More sharing options...
supersizejim Posted November 10, 2014 Share Posted November 10, 2014 I can confirm that I am very happy with my set up. I got a Gen 2 6266. Cant confirm on HP figures, but on my older and bigger turbo it made nearly 650hp. Other than the turbo change, all I have done is put a larger air filter on it, and a Titan crank pulley. Ryan G @bartunning has worked his magic on it, and it is now a lot more of a usable weapon. Boost is nice and early and seems to have a better, smoother and longer power band than the older bigger turbo that I had. Some of this may well be down to Ryan tho. Trying to get down to a rolling road after my car comes outta the bodyshop, just so I know a least what shes putting out anyways. Quote Link to comment Share on other sites More sharing options...

jcbt Posted November 10, 2014 Share Posted November 10, 2014 6466 gen 2 will be around £1500 and that will be the one for me to replace my TO4Z Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 10, 2014 Share Posted November 10, 2014 (edited) theres still alot of choices on that turbo its self what is best ? bearing config, turbine size ect ?? I'm on a ported S cover with a divided 1.00 ar. 6466 gen 2 will be around £1500 and that will be the one for me to replace my TO4Z That's a big power turbo dude, you can't think of them as a 64mm turbo these days, that's a 900bhp turbo, that's more than the stock Pistons will handle I think.

Luxluc Posted November 10, 2014 Share Posted November 10, 2014 The 6266 is rated with 800bhp. Even with that turbo maxed out, you can get to the limit of the stock internals. Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 10, 2014 Share Posted November 10, 2014 I'm so tempted to build the engine and order a 6466 myself. Quote Link to comment Share on other sites More sharing options...

Chris Bailey Posted November 11, 2014 Share Posted November 11, 2014 It's going in for cams and intake first, then see how I get on. Interested to see what you make with 264 cams and the 6266, We'd like a similar setup, you should make over 650bhp on pump fuel I'd imagine.

The Goose pushed 580 on pump gas. I would say an additional 60bhp on cams and intake. Quote Link to comment Share on other sites More sharing options...
