got a sapph 4x4 with t34 with .48 housing fancy a bit more umph wots the crak with a .55 or a .63 ? still want 2 keep it on greens if poss (standard engine)

 

Just get it remapped with a big boost spike if you want to get more midrange punch, or have a .55 exhaust housing as well and light blue injectors or greys to make it even better. Think a level 8 ecu would also be better with bigger injectors. But you may need to upgrade clutch as well if only standard.

 

Greys & T34 .63

 

what he said^^^^^

 

63 all the way..

or greys and t38

 

would their be a lot of difference from say t34 .48 low comp 7.2:1 touring car head greys to using a t38???

 

sorry mate,are you saying you have a T34.48 with touring car spec head?

yes a T38 would make a huge difference,and would be closer to what the head was specced for i'd imagine

 

YESSSSSSS

Probably about another 50-60bhp

T38, good for 440

T34. 48 360-370ish.....others will argue

 

its running a lot of boost on the .48 and i like the way it drives .. i drove my mates 4x4 with the .63 and seemed like forever for it to make full boost but was much more of a kick..

 

sound !!! thats the ? ive been askn. wots the difference ????? think im gonna go 4 siemens (blacks) .63 , 2bar massive tourqe see stu @ msd

 

massive torque is whats gonna kill the gearbox on a 4x4

ive got a t34 .55 and am away to get greys mapped at MSD which will see a nice 380 bhp
