Hi people,

You may or may not know I've got a 1.4 si, anyway for some reason (don't ask why?!?) it felt a bit more powerful today and was much better to drive. To cut the story short I wnat it to be a bit nippier so I was wondering what would be the best thing to do to it.
I really ain't got much of a clue (yet) as to (serious) engine modding so I was wondering if someone could help. I know loadsa people are gonna say either:
i)The si was built as an economy hatch, and it's not even very economical or
ii)Your wasting your time, whack another lump in.
One thing I was wondering about was to increase the bottom end size. I may have just made myself look like a nob, as on here I've only ever heard of doing that to a Turbo'd mota. Would it have much of an effect to mine if I got it re-mapped afterwards? Thinking either 1.6 (xr2i) or 1.8 zetec ? I don't know.
I may also be able to get hold of an RS1800 engine, as my si is cvh how hard would it be to fit?

Anyway thats enough from me, just hope someone can help!

Cheers, Rob.

Okily-dokily, first things first. You don't technically have a CVH, you have a PTE - designation means Pent roof, high Torque, low Emission, and is designed to reach peak torque lower down the rev range, to allow it to use less fuel to produce peak power (i.e. it doesn't like being revved, I shouldn't think).

You best bet is to fit a K&N panel filter, free-flow exhaust (and manifold if you can stretch to it), and fit better brakes to increase your confidence and safety margin a little.

Chipping should help, although if money is no object I would find out if a UniChip could be transferred to a different management system at a later date, as they are custom mappable, and a great investment.

I haven't heard of a cam being made available, though - try Kent Cams.

Other than that, I would just start saving pennies to drop an XR2i lump in - for the same money you'd spend above you could probably pick up everything you need for one (engine, ECU, loom, exhaust system, inlet manifold, fuel rail, and various other bits and bobs. Mounts, fuel pumps, coolant system bits, etc, should be the same.
