... thats a miss!As far as the power drop off, I think I recall a guy doin some R&D on maxima manifolds and found they were very restrictive up high. He actually made his own and gained substantial power up high. I did a quick search and didnt find it fright away but ill see if i can try and hunt the thread down.

You also have to look at the housing size along with the increase in piping length since it's a rear mount. The longer you have a 2.5" pipe the more it will restrict. Same goes with your charge pipes going back up to the front of the car.
You said you wanted to do cams but i seriously would work on what the issue is at hand before making any upgrades. What you have working for you should work great once you get it figured out. Changing something might add a headache to finding the problem.

Thank you for the input guys, Vince, yeah I followed sparks03max's thread since he started it on the org (maxima forum), but I dont have that kind of time or tools. Instead I got ahold of a Z mrev2 manifold with spacer and pathfinder TB, so direct bolt on. The meth is already turned off, car still feels good and with the new turbine housing it lowered full boost to almost 1k rpm.
As for the tranny clutches slipping, I actually thought that maybe my converter in stock form and unlocked is just not efficient at higher rpm's but after looking at my friends dyno I ruled that out, these auto's are tough.

yeah, the price was basically almost a give away, so F it why not. uptop the car feels the same, there is a dramatic difference in mid range gain (whole lot of power and torque), and for the 1st time in almost 5 years of my car being turbo charged, I get full boost in 1st gear.

Yeah, I think if it was a flow issue it would show up on the maf voltage, but instead maf voltage stays up, actually keeps climbing till i let off, its a Z32 MAF and getting aprox 4.8v, The Z manifold gets here on friday, so on sat I will reduce the gap at the same time, what do you guys suggest? I was thinking .030, i have it at .037 right now.
