Skunk2 Intake Mani & Throttle Body?

Would ATR components be better than S2 then? And why?

the s2 manifold is a copy as such of the atr manifold there have been back to back tests done and there isn't a lot between them

Fair enough. And a fair bit cheaper as well I imagine. What bore is the TB though? I think 68mm would be ideal?

If you get a virgin ATR manifold you need a host of bits done to it. Mods done to make it fit a P13 head, IACV adapters, EGR blanking plates, a fuel rail adapter, port matching for a larger TB (ATR TB's are 62mm standard). 68mm TB's are about the limit you can go with an ATR IM, Rosko Racing say port matching anything larger can result in breaking through to the IACV.

While the ATR IM is cheaper to buy than the Skunk2 you have to do some work to it so the economics of both are about the same.

The setup I bought off Dino (originally Taffylude's build) has SK2 68mm TB, ATR IM, Stage 2 Pro SK2 cams and their associated parts.

And that was a good setup?

Think that's what I'll be going for if so..apart from I'll get the S2 IM cos it's easier.

With 11.5 comp pistons and associated bits it made 277bhp & 188lb/ft on it's last dyno by Dino.

The only issue is that once you start upgrading one part you realise you need to upgrade other parts to make your initial mod worthwhile. You quickly end up down the rabbit hole and end up with a car that doesn't resemble what you started with

Is this car going to be your daily Andy?

And what's you actual aim power wise?

It will be my daily initially yes, once I get the standard 2.2 in there. But once I start work on the project engine, it will have to become a track/drag/leisure car once that's fitted.

Aiming for 350/400bhp ultimately.

Your not going to get that level of power with Na easily. If you want that power you should look at turbo, it will be much much cheaper. To get to 300bhp from an NA H22 takes serious cash and I doubt you would be able to drive it daily.

Yeah, I'll be going down the supercharger route.
