Depends how much you want to dick around, and how much you want to spend. When I priced getting a manifold fabricated for a set of AE111 (Toyota) ITBs, the estimate was around $900 - $1000. Jenvey are now doing an off the shelf kit for the BP4W head for GBP611. (About NZD1300).

There are a couple of other items required like a vacuum manifold, throttle linkage and TPS but they don't add a lot more to the price.

The other thing to remember is that you will require an aftermarket computer to drive them properly.

I would say find out what diameter will suit you best. There is calculators online for working out intake diameter/lengths for what power/rpm you are after.

Getting a manifold made up may not be to much of an issue if the throttle seperation is similar to the port spacing. It is possible to cut up a stock manifold and weld a flange on, or if using the bike carbs use the rubber sleeve things.

I remember someone was selling a set of cbr 600 (?) throttles with manifold for $250 a year or so back

a crowd in aussie makes a manifold for dcoe carbs for the MX5.

you could use that with some Injection throttle bodies.
i think it was "injection perfection" selling the manifolds but cant be sure.

ITBs?

Just wondering if this would be worth sticking onto my car or will it just cause me problems/make the car worse?

Hard to say. The runners look pretty short and the flares on the "trumpets" don't look that great. Probably more suitable for a forced induction set-up.

I've seen quite a lot of silvertop 4age's at pick a part lately. Although most of them have been out in the weather for a while.
