Hi all I want some advice from people who have been here & done it.....

I've got a saph cos 4x4 running 336bhp at mo on standard T3, greens, RS 500 cooler-rad, group A air filter, samcos, 3bar, msd chip, msd new wiring loom, 044 fuel pump, msd wring loom to pump, group A head gasket, breather system, etc

I've got a brand new T34/63 & a set of Siemens 55lb injectors to go on, it will b going to msd to get it all fitted & set up.

But
1. Is it worth doing, ie how will it drive different , coming on boost etc as I drove it round with a stage 1 270bhp for 12 years & when msd did the stage 3 I couldn't believe the difference!! In fact I still buzz off it 2 years on....

2. Will I need anything else doing to the engine while its there?? As it's the original engine totally standard apart from the above (62.000) original miles, will it need long studding? As I've already spoke to gears about the gearbox upgrade & quife rear diff, front has strengthened plate in & he said that will b fine. Sorry 4 all the questions but I'd like to hear off people who have been here & done it maybe regretted it & so on....? I will talk to stu obviously but I'd like a bit of feed back 1st.
Cheers Lee
