Hi.

I have a hs4 single for my project 1380 and I'm wondering if it's as simple as buying another hs4 left or right dependant on which i already have, the correct linkage kit and twin inlet manifold to make it into a twin?

I can't seem to find anything on this.

Thanks chris

Not simple, if you want to fit twin HS4s then you would be better buying a matched set.

 

Alternative used by a lot of people is single HIF44 on decent alloy manifold.

Its as easy as you say, no need for a matched pair imho.

Really.. two rights or two lefts!?

No, you ll need a right one normally ( looking from inside the car)
I must say I didnt like my twins on my 1330, might be better in a maniflow manifold
