nigelboyne Posted August 13, 2009 Share Posted August 13, 2009 hi lads looking at getting hksto4z turbo installed can anyone tell what sort of boost this turbo naturaly makes and what rpm it actually starts spooling up. also what boost can i run safely on the standard internals.the goal is to try and reach 200mph on standard engine.

AlanM Posted August 13, 2009 Share Posted August 13, 2009 Not sure when it starts spooling but you will have to raise your rev limit to break the 200mph barrier whatever turbo you fit Quote Link to comment Share on other sites More sharing options...
JamieP Posted August 13, 2009 Share Posted August 13, 2009 T04z is a pretty old turbo now tbh, still good but there is better performing turbos out there now, spool Will be dependant on what hot side you go with, smaller the hot side the faster it will spool but the less power it will make. A good condition stock engine will take lots of boost, certainly as much as any road fuel will allow. Quote Link to comment Share on other sites More sharing options...
nigelboyne Posted August 13, 2009 Author Share Posted August 13, 2009 the limiter is raised to 7250rpm.car is making 470bhp roughly stock uk turbos.really wanted to go for the twins gt2835s but was advised go single. the to4z comes as a complete kit do other makes and what ones would you recommend cheers Quote Link to comment Share on other sites More sharing options...
Lee P Posted August 13, 2009 Share Posted August 13, 2009 If your buying a T04Z kit it will come with a 1.00ar housing, with stock cams it will reach full boost approx 4000rpm. It comes in very hard all at once so produces impressive torque figures. Its good for over 750hp but on a stock engine I would run around 1.5 - 1.6 bar boost which will give you around 600hp. Have a look at Chingy's car which is running one, he has a dyno graph in his garage. Quote Link to comment Share on other sites More sharing options...
nigelboyne Posted August 13, 2009 Author Share Posted August 13, 2009 (edited) when you say 600 do you mean wheel or fly.i see graphs with hp figures but not sure if there at the fly or at the wheels.i have 400 at wheels so roughly 460/470bhp would that be correct Edited August 13, 2009 by nigelboyne add a question (see edit history) Quote Link to comment Share on other sites More sharing options...
Chingy Posted August 13, 2009 Share Posted August 13, 2009 As lee said, I get about 1.6bar at 4000rpm, comes in very hard and agreesive. Running mine on stock internals as Jamie said if the engine is in good condition then you should be able to run alot of boost, Quote Link to comment Share on other sites More sharing options...

Lee P Posted August 13, 2009 Share Posted August 13, 2009 when you say 600 do you mean wheel or fly.i see graphs with hp figures but not sure if there at the fly or at the wheels.i have 400 at wheels so roughly 460/470bhp would that be correct Thats fly wheel, at 1.4 bar on stock tubbies you could get near to 435hp at the fly with an aftermarket ecu but thats pushing the limit.

Hoppy Posted August 13, 2009 Share Posted August 13, 2009 I have a HKS T04Z kit fitted on my Supe Lee P gave a very accurate desciption on this turbo.It starts spooling just after 2000rpm and hits full boost at 4000rpm, and it sounds wicked too!! My Supra is still a work in progress at present, so i'm yet to unleash it's full potential.But i personally love this turbo and i would recommend it Quote Link to comment Share on other sites More sharing options...
