Yes, alpha-n..

You know nothing. S50s have ITBs everywhere except the US, and the poster of the video is from Sweden. Please do your best not to make us Americans look like idiots. You can start by using something resembling complete sentences and words like "know" and "you'd". Thank you.

Tapping is normal for M20s.

thats the best sounding m20 sewing machine ever!

@unluckykid256932 "Tapping is normal for M20s" No. Standard engine in good condition does not have top end tapping, these were among the quietest and smoothest engines in their day. This tuner has probably set the valve clearances wider due to high lift camshaft, high temp compensation or avoiding valve bounce. It might be running non original rocker arms. If a standard M20 is "tapping" you have a worn camshaft, worn rockers and/or excessive valve clearances (should be 0.3mm at running temp).

This is like the 4th vid I'd watched about ITB and they just sound amazing!

I just came

how much and whered you get it? are you happy with the results?

[Lambert0000]

It has slow response because it doesnt have a plenum. Also the M3 donor of those ITBs came with it, and if you want extra performance you get a different plenum attached to some Alpha-N kit. No M3 runs with free throttle bodies, also because they would suck in the engine anything, and would just get hot hair from behind the radiator. If you don't believe this, I am 100% sure you have a chrome mushroom filter in your engine bay.

Purpose of this: this is clearly a race car, hence... performance!

Hi, I wonder why you build up a m20. Wouldn't a m50 be much easier to get the sam power out of it? And it is much more durable! Just curious...

@Mightymini2k ITB setups very typically have slow tip-in or partial throttle response. ITB's are for wide open power. If you're after streetability, try a plenum with a single throttle body and MAP/MAF sensor.

what is the purpose of having this the throttle kit
