68mm powermax vs mtw stage ???

Well I am still trying to finalize my build.

I was pretty sold on MTW but can only afford the stage 1. Sounds like a pretty good upgrade that's still pretty close to stock.

I have read lots of good reviews on the pmax 68mm but it is usually a lot more expensive. But i found one used for about the same price as MTW stage 1.

Just trying to figure out which would be the better upgrade for my build (since the price would be the same). I am using 175cc injectors with stock nozzles and a bunch of other normal upgrades.

I have heard the pmax 68mm is not as good as the mtw stage 3, but how does it compare to the stage 1 and 2 mtw.



Also this is the last item I am waiting on and I can have the pmax 68mm right now and I am not sure how long I will have to wait for the MTA stage 1

but could you elaborate more???


I have read a couple of build threads on the 68mm powermax hitting between 550-625 depending on injectors.

I am trying to compare the 68mm pmax to the MTW stage 1... (the two that I am looking at are the same price)

Does the 68pmax even compare to the MTW stage 2??? Or do you have to bump up to the stage 3 to equal the power of the 68mm pmax???


Also I have not read any negative threads on the 68mm pmax yet... although most of the threads I find are about a year old and people have not been talkign much about them since then

For the 175/stock personally I'd go w a billet hybrid w the new wheel. That's still gonna leave you a little room to grow

Or you could get the PMax and have matt or adrian or nate order you a billet wheel for it. The billet wheel Pmax is supposed to be pretty good too. The pmax had surging issues from what I recall and the billet wheel cures that up.

Just another option.

Isn't a 68mm powermax just a modded powermax to fit the 68mm compressor wheel and I'm assuming they change the turbine wheel also to keep it from surging. But I'm gunna say it won't last long if its based off the gt37 chra while the stage 3 which is a 67.4mm? Is made from a gt40 chra which to me seems a lot more reliable.

Thanks for the great info


Actually from the research I have found... The turbine side is not changed

If the turbine side isn't changed then just buy a 68mm compressor wheel and go have your stock housing machined to fit.

That is a thought... the only reason I am looking at the 68mm pmax is because I found a good deal on one for around $1000 (no core required)
