I have a 2wd cossie with 3" Mongoose, KN, Montune Chip, Turbonetics T34 ar.48, grey injectors, low compression pistons, and ported top (???). Had it on a rolling road and the results were 350bhp@6100 rpm., and 417nm@4400rpm. 1,6 bar.

Will a ar63 exhausthouse be a good upgrade, or won't it make any differance?

corse it will change it

depends what you want out of your car really mate.

for better response and less lag, 0-60's i'd use the .48

for more top speed and more power on boost (but with a little more lag) go for the .63

You would need a remap too if you decide to change

.63 pulls like a train when it get going, right up to the max revs!!

If i buy a .63, should I buy BD-14's too?

I have not got them!

You need to have pocketed pistons for bd14's........BD 10's i think are fine for normal pistons.

What i mean in the statment above is that you don't run out of puff at top end like you do with a .48 housing.

i was in the same boat mate, i went for 43 housing as i hate lag but now i am restricted to under 400bhp until i change it.

but my car is running sweet and rapid at stage 3

just changed my 48 for a 63 well worth doing not that much lag

im running -63 with greys, 500 i/c low comp, worked head and
got 382bhp with fooked exhaust and tesco petrol, dont find
it much more laggier than when i had a -48 and like said
above it pulls all way to 7k

As I told you before Triggerhappy, bigger AR - more power on top.
