Hi, would like some advice, i have a 996tt with ap bov, ap induction and a 100 cel 3 inch exhaust aswell as a flash. Ive ordered some tial a28 turbos, what are needed mods before fitting and what are the best mods for future to get most power, thanks in advance

 

You definatly need to upgrade injectors, more fuel more power, ask your tuner what they recommend, you will need to retune.

 

As bimmer said you will need a new tune at a minimum. Larger injectors + a tune are a high yielding next step. After that I would look at new intake piping and possibly some headers (controversial). A race tune can get you 15% more or so if you can get the gas...

 

You need injectors and ICs... as well as a good custom tune...
Let me know we can help... I have a few guys in England running around with some fast cars...

Thanks for the advice, so how do these compare to 24/18g or 24/20g? What sort of bhp is possible?

 

These turbos can out run both 18g n 20g turbos (at least mine did) with quicker spool up

 

A28s will run with most 24/18g setups with similar supporting mods. To run with a 20g they need pretty maxed out supporting mods and probably some weight reduction. They spool up faster than both 24/18s and 24/20s so they are more streetable. The highest bhp I have heard is around 800 crank (~670ish whp) from the P800 Switzer kit. They claim there A28s are a modified variant though and I have not been able to find out how much boost they are running...

 

Right on Mark! I forgot the ICs. You wont get far without them!

 

Good to see a few of the UK guys starting to try out different turbos
