Hi guys, if you could take a look at my vid and let me know what you think, cheers.

Its definitely an option. You would want to brace the manifold back to the block though and im not sure if theres earths on the chamber that would need relocating. Or you could get it welded back together which would be a better option for rigidity.

Or the other option, you could stick some bike throttlebodies on instead. A few guys have run triumph tt600 throttles on stock management.

If you going to cut up any inlet. Look at the Corolla one. For a bolt on 10bhp. 85ps instead of 75ps....

Id say the corolla one is a bit small too.

Cant see why it wouldn't work tho.

that would work fine but cut as close to plenum as possible as there will be less offset isseu then of the runners meeting plenum

if your cutting half way down the runners will be ofset by to much

i would use solid weld not silicons as the plenum is to heavy needs bracing

i think you would need to take the "offset" into account if you did cut...as the plenum would now be likely further away from the head when flipped around and i'm not sure how much space you are working with in relation to the "side" of the bonnet---assuming you fixed the touching at the top of the bonnet

i'd prefer you weld it in place too...instead of the silicone joiners

as morgey said, the throttle bodies sound like a good option for you

are you referring to the 5th manifold counting from the left?

if so, i'm not sure how easy it would be to flip around and rejoin given the pipe/runner work

i do agree it would be nice on a n/a engine torque wise though

As above. Get a set of itb's slapped on.
