If you bothered to read the whole post, you'd see that I stated GTM's prices as well as a complete/machined and assembled short block. Let's not turn this into another f'ked up debate thread... Both kits come within reason of the other's prices. and offer 4+ liters of total displacement. The ONLY difference in the prices is that with GTM's parts only offering, they don't seem to include the sleeves. I could be completely wrong, but according to the announcement thread they posted a while back, sleeves weren't included in the parts only quote. I also stated their complete kit price for what it's worth. Very nice gear from either shop. But I digress...
Great work by IP and great things for the community as a whole. I'm always happy to see new things in new forms offered up for the masses.

But considering the stroked 3.4L supra with less displacement has made more power than the Z "stock" displacement should give you a "reference". Plus at some point you hit a ceiling anyways... OF course you can make more power with stroker kits..but the point was that sleeves allow you compensate with more boost...
don't get sensitive. I like the BC stroker kit

Your first statement is presented in a way that would lead someone to believe that the power achieved by utilizing a stoker kit can always be compensated for by sleeving a block and using more boost. That same someone might be led to believe that you are not able to run as much boost on stroked motor as you would on a non-stroked motor.
My point is that it should be clearly stated that if you have the same exact set-up on two seperate motors except for the fact that one is stroked and one isn't, generally speaking the stroked motor will have more power than the non-stroked motor.

The turbo that you select is going to be the limiting factor for HP on any motor. A GT47 turbo can only support X amount of airflow which equals X amount HP whether it is on a 2.0L DSM or a 4.2L stroked VQ or a 450+ cu inch big block chevy. If you put the GT47 on all three motors the resulting maximum RWHP will be roughly the same on all three if the turbo is pushed to its limits. The larger motor will make slightly more HP and a ton more torque of course. The HP difference due to the turbo being in a more efficient range of the map and back pressure being less. Obviously the TQ is greater because the extra displacement gets the turbo spooled quicker at a lower RPM. Therefore a supra with a GT47 and a Z with one will ultimately make about the same HP..... Z making more TQ and I believe it is a bit lighter of a car?? correct?? So the Z should win
Now to the question of how much HP the 6 spd Z tranny can handle?? I know the supra one can take 1500. Anyone know the limits of the Z manual tranny??

I'm guessing that as long as you don't abuse the transmission (drag race, powershift), it should be good up to 1000whp (or more) before something actually breaks just from shear hp alone. It's been proven that a stock Z can tear up a trans, and that a 4.2 stroker with 8xxwhp can do just fine with that same model trans.

Your power curve will not be dictated by how restrictive something is or something is not, your power curve will be dictated solely by the size of your turbo.. However if you do have a restriction somewhere, it will either stop making power beyond a certain psi, or if you do unrestrict it you'll notice it will take less pressure to get to a certain horsepower. Again it will not dictate your power curve.
thanks
thanks
as a good friend suggested me.... torque converter maybe the issue
