T14PPA Posted May 9, 2014 Author Share Posted May 9, 2014 If you want a cheap turbo at least buy something that's tried and tested with the NA-t crew. Otherwise buy a second hand precision unit. Fly is breaking his NA-t setup. If you want a cheap turbo maybe consider his T61. Otherwise keep an eye out for a second hand unit on here Ive got a cheap gt45 that ive been running a year with no problems. I just thought the garrett would be better - - - Updated - - - I know of a Supra in the uk running a truck garret and its an immense and reliable car! Thats what i thought mate Quote Link to comment Share on other sites More sharing options...

When you use higher boost but far less pistons and engine size, the running tolerances of the turbo are easily met. You also then benefit from running a garret unit that is far cheaper to service and repair as apposed to its petrol designed counterparts.

Also the actual unit itself is cheaper in total. I would imagine a huge litred truck engine would create a shed tone of heat through the turbo too? All i can say is that i know a setup running one and its a bombproof. But im sure a huge amount of time went into the turbo choice still. Even with it being a truck one.

Chris Wilson Posted May 9, 2014 Share Posted May 9, 2014 It's a totally unknown unit, he has no idea of the air flow map for it, or what seals it has. Some diesel turbos have less seals than petrol ones, as trucks do not usually have throttle valve and "throttling" is done by fuel flow. So running the wrong type on a car with a petrol engine with a throttle body will cause them to just smoke like hell and burn oil like there's no tomorrow. There's a vast amount of science in turbo types and sizing. But if you feel it's worth trying, with all the bespoke pipework costs, then fine, give it a go, but it'll end in expensive tears. It actually looks bigger than the one on my Mercedes truck, and that's a 12 litre engine.... Quote Link to comment Share on other sites More sharing options...
