Question for the turbo gurus out there

[4seasons69]

My turbo is going to cost more to fix than I would like to spend on a used turbo. I can get a brand new center section for about 950 or map has gt4294 listed on their site for like 1200.
Since the its already getting spendy should I look into going to a gt4202 or should I run the risk chipped exhaust wheel until I can get a billet version of the 4294 or 4202? I would also be willing to go away from the gt42 style turbos for the right one.

Basically I'm looking for your thoughts or opinions on what a good turbo would be that can support upwards of let's say 800 to1000 hp at the wheels at map?

(I have spent lots and lots of time doing research on turbos the last couple months and my brain is on over load right now. Just need a little help. Thanks!)

I have a slightly used GTX4202 with Tial V-Band housing on it for sale. They are an crazy expensive turbo though.

Ha yeah I know they go for like3k new. If I go the gtx route it probably won't be until spring because the engine rebuild is already quite spendy lol. but pm what you want for it ill definitely keep it in mind

I say get a small turbo first and see what you break.

6266 will only do 860 as vassil has shown, but probably won't wow people with the hood up.

Ahhh yea only 860 lol. Isn't he on e98 though? I want to stick with E85 for now. The car is setup for a gt42. It made 760ish at map on a 4294. but if the turbo is the right price I don't mind having to change the intake and exhaust. Honestly i dont care as much about wowing people under the hood. I care more about the performance and power.

Basically if I can go to a little smaller turbo pick up some spool make as much or more power on E85 and get the turbo, intake, and exhaust for around 2kish I'd seriously consider it. If I'm looking at more than 2k ill prob go ball bearing gt42 or go gtx

What about a billet 6766?

[Halon]

It's sounds like you want to keep cost to a minimum. So I'd say if everything is already setup to mate up perfectly to a GT42, then just stick with that platform for now for simplicity sake so it's just a bolt up affair without having to tweak piping and what-not. Little tweaks here and there can add up cost wise.

Without knowing what your current turbo is, or what exactly is wrong with it (you mentioned buying a center section, then mention a chipped wheel, what all is wrong with it?), it's hard to say what's the best path to go as far as repairing or buying new.

What is your current turbo and what is broken on it?

GT4202 is pretty old school technology.

[Shane@DBPerformance]

Don't expect big gains going from one large turbo to another large turbo in roughly the same size range unless the old turbo was maxed out and dropping boost/airflow a lot or you crank up the boost, which will probably take better gas. Especially if you retain the same size exhaust wheel and exhaust housing.
