anyone read the new thing for the 998 in the new mini mag, looked appealing. wondering what people thought? should i still go for 1275 engine? its jus my 998 is pretty mint, and its a big risk switchin engines.

[nmt_oli]

Id go with the 998 for now, thats what im doing!

got twin HS2 lined up, and already got stage 1 kit. just looking for a suitable head now, and it will be off to slarke race engineering to be tuned to perfection

i though the same after reading it, do u think the 91bhp was genuine? id love to try it but like u im in two minds.

new mini mag??

is the post being rubbish again

Im thinking of the 998 option too, much cheaper than buying a 1275.

I think the 92bhp was close to a genuine figure but the 70bhp from a 998cc with only a Stage 1 kit :erm: Isnt that a bit high for a cheap modification? and isnt the 998 only 34nhp as standard?

:wales:

Off topic but is this bhp figure at wheels or fly?

[miniboo]

must be fly

[nmt_oli]

91 seems mad for a 998, even with head+ carbs+ stg1 im only expecting around 55-60hp, if that. to be honest i dont really car about the figure, as long as it pulls better, is smooth and fun to drive!

What the hell was in the MiniMag?!?

This topic is worthless to those who haven't read it!!

[MaryQuant88]

Go out and buy a Copy :fear:

Its all about the shortage of 1275 engines and the bloke decides to tune a 998 to 91bhp, using a 1275 head, 1.75 SU Flat Pistone etc

No, 91 bhp was NOT a genuine figure as they stated a stock motor on those rollers made 60bhp!!!! So take off the 20bhp over read and that's about right for the spec, (70 bhp).

What a bad way of doing it though, spend a lot of time and money sinking valves then having to use a low lift cam when 998's love high lift and short duration.

I had a genuine 80bhp at the flywheel (on a dyno that read 40bhp stock), from an SW5 cam, 12G295 cooper 998 head, (they come up on ebay regularly), minispares ST1 kit with the drilled stock air filter housing. This is bolt together stuff. Morspeed do a recon, unleaded conversion and mild port on these heads for £250, though I just used an additive. Was great fun and easy to build.

Performance? Sub 10 sec 0-60 and GPS reported 110mph top end on 2.95 city E diff.

Personally, I can't see the point of flogging the nads of a 998, unless it is restrictions imposed by competition...

My answer is jut to remove the 998 and put a bigbore block in it.. and be done with it..

Fair comment, but consider cars like above that are pretty good condition, add a 295 head and st1 kit, 40% power increase and cheaper insurance that a 1275 with no engine swapping. For all out power, a big bore is the way to go, but my turbo 998 insurance quote was £180 less than a 1380 and will be much faster with more torque.

I am competing in the up to 1400cc hillclimb class though, so it is for a reason, but fun anyway.

[Guess-Works.com]

Not doubting that, but how often is the 998 rebuilt, vs the same 1380 ?
