The xover pipe on my JB is ridiculously narrow at the turbo end,, even looking at the JA's it loos different, I've got a pipe that'll fit, so my question is it worth it?? would I get better bottom end / top end???

it should make a difference but dunno if youll be able to feel it

Ofcoarse you will, less restriction = more air in = more air out= more power

I'll put it on tonight ready for tomorrow's drive to work...
:beer

let us know what sort of improvment it gives :)

I am pretty sure I know what you are talking about. But to be completely clear.

Exactly what is the X-Over Pipe? Is it the pipe that runs from the IC to the turbo intake which goes over the engine, or something else?

X-over pipe means cross-over pipe, its just the pipe the crosses over cam cover.

Thought so

Mine is rubber, but same diameter from I/C to turbo

AHhh, yup yup, yours is intercooled isnt it? Those pipes are a bit larger then the non-ic ones, but ive heard of people having problems with em expanding and blowing off... Never had that problem with mine tho :)

Yeah its intercooled. Pipe inside diameter is equal to the turbo intake size.

I have heard they expand and retract, but mine haven't blown off yet.

well, the first I noticed was the exhaust not, deeper?, and the bottom end isheaps better I can drive off boost all day and still have plenty acceleration, turbo lag is improved... it's a good cheap mod for the money.

My only explanation for the OEM xover pipe, is that the engineers wanted to slow the thing down or something..

Good to hear it worked for your car, I knew it would
If you wrap it in thermo tape, you'll get some more power as well

would you really want to wrap the cross over pipe in thermo tape? if it isn;t intercooled then you'll only be insulating the hot air and keeping it in the pipe, atleast without thermo tape in this kind of setup the pipe can act as a kind of heatsink with the air that passes over it from the factory bonnet JA anyways.

But if the car is intercooled then ofcourse thermo tape it to keep the cooler air in.

Sorry maybe i got my wires crossed but do you have an intercooler?

Far out Benny, is it that hard to figure out? The idea of the tape is to stop all the HOT air from the motor heating up the pipe, thus making the air IN the pipe hotter. It wont cool the air, but it will prevent it from getting any hotter than it allready is. :)
and no, no cooler.

Nope.. I agree with far our Benny. I wouldn't wrap hot pipes.

The air inside that x-over pipe can reach upto 80 or 90 degrees C (no intercooler). The air in the engine bay will be a lot cooler than that.. especially when the car is on the move. You would want to leave that pipe un-wrapped so it can radiate some of that heat out.

The only pipe I would wrap would be between the intercooler and the throttle body.
