Cant see the point and i'm not sure it would work well on a standard engine. With head and cam you'd probably feel the benefit of the Weber carb.

It's a possibilty once you have improved the engine in many other ways... Would not be my first choice for a carb upgrade - in fact , probably my second last - just before the ghastly 28/36 Weber..........

What would be your choice? im just looking for that bit extra go.

Depends on spec of engine - HIF 38 on a GOOD inlet manifold is fine for an otherwise standard engine - going up to an HIF 44 as the modifications stack up.

okay, just i've heard that the webber does a good job and will gve that bit extra poke, or isnt that the case?

on a 1275 yes but not on a 998 its will over fuel it

[bmcecosse]

" will over fuel it " Not if it's jetted correctly........

[Ben10Raw]

My mates dad knew some one who had that set up and his ran fine. So it got me thinking i could do the same, but run it past yous' on here first

[bmcecosse]

Go ahead - the problem lies in getting it jetted correctly........

get a modded cylinder head, cooper freeflow manifold, hif38 on a stage 1 inlet, K&N cone filter, and a cam if you have the ability

I have a stage 1 kit, and thinking about changing the cam also. so if i get a new kent cam then the webber will be suitable?

[danrock101]

depends on what kent cam it is, fit a better cylinder head, I still think a hif38 will be good enough up to about 70-75bhp. I'd rather fit twin HS2s than a weber 40 on a 998 personally, generally with engines you want the smallest you can get away with for the power you want

Thats the horsepower region im looking towards, i was thinking of a kent 286 cam, what you recon? i was looking at the twin HS2's trying to figure out whats going to be the best for a 998

[danrock101]

A kent 286 will be too much, a 276 would be better... Twin HS2s are great for a 998 but I would use a hif38 to start with.
