what is the difference between p and q trim?

 

also whats the difference between divided and un-divided?

 

Divided and undivided refers to the exhaust housing entry point. Where the manifold bolts to the turbo. Divided means there is a splitter in the centre.

I also want to know the difference between p and q trim wheels. I've heard that the q trim will flow a lot better. Is this true?

 

I don't know if it helps or not, but I've always been told that Q trim wheels are better on ported motors and P trim wheels are better suited for stock ported motors. I may be wrong, if anyone would like to either back or correct my statement the please feel free to do so. Laterz.

ok cuz i jus pikced up a turbonetics 60-1 with .96a/r and .70 compressor side it's undivided but i will be goin ported this coming winter

 

That's a nice turbo you got there. P-trim will be fine on such a turbo. Have fun with it!

 

oh i plan on it

 

if you dont mind me asking how much do 60-1's go for in the US?

Cheers

q-trim is a combination of a larger exhaust wheel and housing. the larger wheel is harder to spool but makes more top end power.

 

u think an extended street port will elp or even a pb cuz those are the 2 that i am contimplating on doin this winter

and i don't know what prices they go for i got a wicked deal on mine 1000 bucks for the turbo and a custom manifold that the guy i bought it is gonna make.

 

P trim has a 75mm inducer and 67mm exducer give or take.
Q trim is larger,c cant remember the exact numbers but its something like 79mm inducer, 71mm exducer

 

Prices for turbo parts can be found at the turbonetics.com

the wheel is 50 and the housing is 180.

Thats if you already have the to4b like me.
