New kid.

[306pc]

Hi folks.

I'm new on here but I've read quite a bit already and the knowledge on here is unreal. Maybe I'll be able to pick a few brains and raid a few sheds as I turn my new love a 98 Diablo 306 1.9td lx 5dr mule into a racehorse.
I work in a huge car supermarket in Derbyshire and sell and see really new cars all day. They are so soulless. I love my 306. It's a tryer, a fighter. I love it.
So, it has a Lucas pump and a T2. I've done the stage 1 tune and popped a decat on there and I'm now at 18psi with the wastegate fully open and boost controlled by the fuelling. I get a nice haze on full boost and no smoke. I don't really want the smokey look. As I burn past I don't want them thinking its about to blow up! I got some front gti6 shocks and lowered it 40mm, back end to be lowered to match very soon. gti6 front brakes also added. 2 sets of cyclones but I've seen some Mi-16s and I might not be able to resist them.
I now feel that the car is being held back by the pump, and I may aswell go for a bigger turbo at the same time as putting the Bosch pump on. I like the way the T2 spools up, especially since the decat went on now at peak boost at about 2.2k so I'm shying away from the TD04 as they need revving hard right? So my 1st question would be which sounds the better option turbo out of the T25 or GT2052s (are they both bolt ons?) and second question 9mm or 11mm pump?

Any advice appreciated.

Nice to meet you all. PC.
