thats in the 230bhp section. there is no uprated gasket and head studs are generally needed for over 18psi as it lifts the head. id put that in the 300+bracket.

porting adds power all over the rev range, its not as good on a turbo as a nasp as the air is forced in but its said to be 15% gain on a nasp and 5% gain on a turbo.

ive not seen anyone with an aftermarket inlet manifold (except myself ). most use an M series inlet with the throttle body re-positioned to open the restrictive part of the manifold.

Car tax is primarly based on age and then either capacity or CO2, anything before 1st March 2001 is based on capacity, anything over 1549cc is currently ?205pa, the good news is this rate can be applied to the age of the vehicle OR the engine, which ever is the oldest!

I read somewhere that the hubs and driveshafts where different ? ie you needed the 420 ones ?

Or is that only if your are converting a 1.8 ?

Its the loom im not looking forward too, seeing as im going down the "hard but cheap" route

The only other thing im not sure about yet.. so lets say i have fitted the bay loom from the 420 complete, then why do i need a 220 loom for the engine ... or is that if fitting a dizzy lump ?

Being a wasted spark Ti lump, is it not possable to simply use the 420 gsi engine loom ?

Im sure i will answer my own questions in time lol, just keep thinking about it !

Great guide though,it was this guide that made me hunt for a 420 complete tbh, loom, pas pipes etc etc,sod looking for all that on ebay or scrap yard hunting.

I think the hubs are the same, but you might need to use the zs cv joints on the 420 shafts, the reason for this is the different abs rings, the 420 is most likely 27 teeth and the zs 42 or 43 (can't remember which) lol, worth checking the 420 ones though they may be good to use as they are.
