+1 on PE TT maxing out way before the limits of that block are reached.

Didnt somebody say the most that kit would do would be around 550whp? You dont even need sleeves for that....

The PE TT kit with supporting mods is good from 500-550WHP... If you push those turbos beyond that point you're going to be making a LOT of heat! Heat is the Enemy and will destroy any motor over time.

Just because you have a sleeved block doesn't exclude you from engine failure, it just means the cause will most likely be the next gating item...

idk i rember reading some where PE was breaking into the mid 600whp, but i think thats with the ubgraded turbos.


It would still be nice to see what PETT can really do.

550-650whp (depending on the dyno) is a nice comfortable limit for an unsleeved block. For all we know, the stock block can probably take a lot more, but until we know for sure, we'll sleeve them when customers are looking for 650whp+.

Unsleeved blocks can be very stout...but only time will tell.

Your engine build list looks very much like the engine build packages listed on SGP Racing's website. It is similar to their "Ultimate Long Block" which they state is "good to 850+ rwhp". Therefore, I agree with the others that the PE turbo kit will max out way before your motor does.

So is SGP doing your build? And if so, why don't you just ask Mark about it? He'll give you a good honest answer about what your max boost setting should be with the PE TT kit.

I was just wondering, what is the limit of the APS kit. Not the extreme. Just turbos. And how much psi can the APS intake plenum withstand? I ve heard off 15 psi? Also having my block build and need to know the limitations for my aps kit. Block can handle it.

Im actually getting the motor used from vq35carel who used to work from xs-engineering.. i has 2500 miles and yes, it was built by SGP racing... I confirmed all info with SGP that they did built it will all those things, and with xs-engineering that the engine didn't have a problem as far as they know. so... IT CAME WITH TWIN TURBO'S TOO... So, i want to push it as conservatively as 550 to the wheels... wish me luck

Nobody has really pushed the APS turbos from the standard kit with a good build since pretty much all are still stuck with the internal wastegate setup. I think once there are more external gate standard APS kits on built motors, you'll see well over 600whp @ 20+ psi. The turbos are far from maxed out at the 15-18psi that most people with built motors currently run.

i will let you know here in a couple weeks after a certain motor is broken in what the APS kit will safely do on a fully built sleeved motor...

From what I have seen, the APS TT reg turbos are very very efficient. We consistenly get more power at a given boost level, when compared to Greddy...in the sub 14psi range. After that, the Greddy's pull ahead a little bit.

It would not surprise me at all to see 650-675whp out of the APS TT's....depending on the dyno used.
