I'd look at a swiftune SW5, no question. You can run standard springs with it but I'd replace them ata matter of course. Swiftune can supply them too in kit form for the whole lot.
Deffinately new follower's, but nothing fancy really needed. Get them from Minispares or swiftune if poss, I've heard of others shattering.
I used to run one of these in my 998 cooper rally car, great cam, not lumpy with loads of torque.
Failing that Piper 255 or a 997 cooper cam.
Dont forget you will need to time it in properly too. I used a swiftune duplex set that has offset keyways to get it right. It wont slip neither, but you could get away with a offset woodruff key (minispares/minisport) if the timing is close and it is allot cheaper.
You may have to change the oil pump to match.
As far as i know, M&Ms dont do these kits.
Oh and I dont work for any of these company's!!

I think that is very good value and it really is a great cam for fast road work.
Put's the torque just where you need it, people get too hung up on horse power figures. Great if your racing it flat out all the time but anything else you need torque.
That's the stuff that accelerates your car!!

olly, if the rest of engine is a std 998 there's not much point. From what I have read on here, finity and the books most optimal lift is 1.3. Price per BHP you would be better with a stage 1 or if you have this then think about a new head, stage 2 or 3.
The best advice I have been given is read, read ,read ask questions of reputable engine workshops then work your own way over what seems to be the truth. When speaking to people there will always be the same topics cropping up.:D

The cam should make a differance. If your insurance CO has problems with the upgrades have a shop arround you will find someone to give you cover

High olly, i presumed that you had the head sorted and the cam was the next stage.
If you are not presently building up the engine and it is in the car with no immediate plans to take it out. I'd do the head first. That sort of money would get you a cooper head and that would make a fair amount of difference straight away.
Putting a cam on a standard head will help but it is not just about how much lift it has, its also the profile and cam timing that creates the power.
If the engine is out then it would make sense to do the cam now and change the head later.
Hope this helps.
Oh and dont bother with 1.5 rockers on a 998. The sw5 has enough lift as is.

Hi Olly, I'm not up to advising on performance enhancement so I wont comment on that. BUT. imangine the worst scenerio.
You have done the coversions. you,re out on your own (as we drivers often are). You have a smash and are injured, you are carted away in the meat wagon to nearest A&E. Your car is trailered to a compound out of your reach.In the case of where the police arrange for it,s removal they will have it examined, run it through the PNC for MOT Insurance etc etc (the list is endless)
In the mean time the insurance assessor comes along and before you can say boo to a goose he announces "He hasn't declared this that and the other so he hasn't stuck to his part of the contract by not informing us therefore he's NOT insured." Ok as I said in the worst scenario. They can refuse to insure you again and if you don't declare that to the next insurance co. you won't be insured EVEN if they take your money and give you the Certificate they are quite within their rights not to pay out. In the meantime the police could prosecute you for not having insurance + whatever they want throw at you.
Sorry to be Blunt but it is always advisable to inform them of additions ect otherwise the complications that follow can be horrendous to say the least.
This also icludes notifying them of accidents whre you are not making a claim on them!

yeh thats what i was thinking that. but as my dad has said and afew other people that if its acutualy under power now then what it was origonaly all you doing is tuning it up to its origonal state. i have afew options that i have to make my mind up on either get a new stage 2 head on it and declair that or get a bigger engine but that comes back to the higher insurance issue

Olly, Its wise words from Tony. If I were you I would check with the insurance Co as I think the question they ask is "Has it been modified". Getting caught out could cause you a great deal of problems, problems that you don't need in your life. I have a friend that had a lot of trouble with what he thought were minor details that is ending in them not paying out on a 17K car.

mm I'm not sure I think I read somewhere it depends on what oil pump you have installed and if you change or don't change the timming setup. Most people I think switch to an adjustable setup so that the cam timming can be set spot on, if not you need to use off set keys. This is just from what I have read in the past, so you are better checking.
If you speak to the company that you are getting the cam from they should beable to advise.
