Just got some cash together and want to take the 3-door to 300+bhp.
Any idea how much it will cost? or how long it takes? who does the conversion the best? I was thinking of Mr Shead....

Where are you local to?
I think Castle Performance in Stoke are good, I think it is them that John Felstead uses for his Westie, though I could be wrong.......I wait to be either corrected or agreed with

300bhp is ***** power mate.........you might as well go to the 330bhp conversion. What you need :
3 bar map sensor £75
4 x 803 injectors £280
-31 actuator £75
Chip £200-£250
Grp A Head Gasket (especially on the 2wd cossies) £250-£300 fitted
I assume you have an uprated filter and straight through stainless exhaust system.
Take the above prices as your base figure and find out what the tuners quote you for the lot, and then you will find out how much labour they all charge. The job will take no longer than a couple of hours (The head gasket may take up to a day cause the head will need to be machined).
Regards,
Shaun.

Just before Christmas I had done a deal with somebody off the RS board to buy a Sierra 430bhp motor. I had organised to keep the engine and sell the car on to somebody else. The guy then sold the car to somebody else!!!!!!!!!!!!!!!!!!!!!!!!
Basically the money is still in the bank waiting to be spent. Realistically I am waiting for a mate to conclude some testing on a Xtrac Straight cut box. As soon as it has passed the testing stage, I will have the whole lot done at once, but because of the gearbox testing it looks like it wont be until the Summer now.
It will be a 420bhp conversion.

Xtrac without doubt are the best gear sets in the world. The gear kit from them costs about £2500. A Grp N big tooth kit from R&D costs the same amount, and WON'T handle the power. It has to be straight cut (especially for that rally like gearbox whine!!!! ). Quaife want £10k off of me for a Grp A box to handle the power!!!!!!!!!!!!!!!!!! 
Do the sums, matey.

2nd hand Grp A boxs are like rocking horse poo......good ones anyhow. And then you are still required to spend a few grand for a 4x4 one AND then you will have to get it serviced anyhow.

330 sounds nice mate, but will the clutch, gearbox and drivetrain be able to handle it? Will I have a relability problems with the upped power?
also, will I be able to handle the power? I'm running 15" wheels with mintex pads on standard discs, She's been lowered on chassis dynamics springs with standard dampers up front and gas Spax on the back. will I need to change this? particually the wheels cos she catches me out all the time and I'm worried I'll stuff her if I up the power.

All the transmission will handle that kind of power, with full reliability. You will need to check with Mark Shead/Castle Performance/Harvey Gibbs that the block will handle the boost, as I know that 2wd blocks are not as strong as the 4wd ones.
As regards to you being able to handle the power, I can't comment mate. All you can do is drive to your ability..........but I do know of several people running the 420bhp conversion on RWD with no problems. All of your suspension/wheels set-up will be fine.

Astraboy, take your car to SCS for the best service (and price) IMO 01733 576614. Harvey is the real cossie guru
Shaun,
The gearkit is made by DP Engineering and not xtrac. The mental is however treated by xtrac. If I was you at that power level I would get a quaife gearkit (or better still the 'swedish gearkit') supplied and fitted by DOME - 01527 577551. Do note that Martin Hadland has had the quaife gearkit for over five years and only recently had problems due to the box not being put back together properly after it was stripped for a check. DOME has sorted it now.
I am also going to look down another route now and use a 2wd gearbox(T5/T56) with a remote transfer box. May even chop the transfer box from an MT75!!
Cheers,
Dan

Astraboy,
My saff runs exactly the spec as described by Shaun. It's a lovely amount of power, but a little difficult when trying to keep up with Mike Rainbird!
Gearbox and clutch should be okay on that level of power.
Mine was built by Harvey Gibbs at SCS.

thats my main problem. I've just about mastered 285bhp but she still catches me out from time to time. I worried that 330bhp will do more than threaten to throw me over the armco.

Astraboy,
330bhp you will need a clutch,cos the standard one will slip a bit
use the orginal clutch cover,and buy a alcon 6 plate paddle clutch,
and the feel of the pedal will be the same as standard,you willnot know that you have a uprated clutch.
I think I have meet you at Brunters, with Redline mag I owned the moonstone Rs500,you was the lad with the white 3dr,doing a few donuts!!
