I have both a r35 GT-R and 996tt, yes the gtr (VR38 engine) is also upgradable, but I would take the mezger anytime for any non drag racing related setup

the new 997.2TT/S, 991.1/2 TT/S arent real dry sump, if going to use them with slicks just take care, other than that I see no draw back.

I believe the Mezger unopened record is 962whp? Regardless there are tons of cars running around making 650-700whp on stock motors, add back the drivetrain losses to the whp figures, and you have 900BHP stock motor cars running around just fine, I would say the Mezger engine reputation is well deserved and far from overrated.


What kills these motors, and mostly other tuner motors, even the "Indestructible" 2JZ is torque. As the turbo technology advances, these cars are getting faster and faster every 5-10 years, more power and less lag coming from smaller turbos, results in more available tq down low. If you have one of these turbo setups on a stock motor, I would make sure your tuner is aware to bring the tq on slowly in the low rpm range to be easier on the rods.


On a stock motor, I would be more afraid of a big VTG setup on "kill" using ethanol than a much bigger GT3582r 93oct tune setup.

GTR rods fail around the same torque as the Porsches, maybe even 10% less.

I understand that sudden spikes in torque and how the power is delivered reduces risk, but if the rods can "only" hold ~650torque reliably AND cost $7-10k to replace, doesn't that make the strength of this motor overrated?

On the stock set up which I ran for 8 years and 60,000 miles whilst the turbo was a daily I never felt I got any meaningful torque till about 3000rpm. In fact may sound strange but I got more torque spike on stock set up than on current bigger hybrid VTG set up. Pretty sure on current set up my torque is pegged back to something like 580ft lbs in non sport mode and 640ft lbs in sport mode. Have a dyno of the pump tune somewhere if you want to see it. Peak torque hits much later too at circa 4000rpm but theres good torque everywhere. On a turbo powered engine your tuner can basically model how much torque he wants and how / where in the rev band it comes in.

Mezger is a good engine. McLaren the only other manufacturer making engines of similar quality i.e. true dry sump designs with fully serviceable racing block. Having said that I blew my stock engine on a long high speed run at 175mph once! A tuner hadn't been anywhere near the car when that happened. A liner just melted after 5 odd mins of high speed running in 6th gear.

I may be wrong but I don't think the new 2017 991.2 turbo S has a proper dry sump engine? Is this correct?
