As above really, am looking at going twin scroll as opposed to rotated on my new engine build. Mainly as i'm not after big numbers just want something thats minimal lag but useable power on track. If you was to ask for a figure i'd say i'd be happy with 400bhp.

It will be going on a 2.1 with avcs, 6 speed box squeezed in to a MY98 wagon shell. Would just like to hear from anyone who has a similar set up and the pro and cons about the set up.

I'd plump for a TS SC42. The SS version is well documented as doing the biz - so the TS version should spool blindingly on a 2.1/AVCS combo!!!

Thanks for the reply. I had been wanting to go rotated but after trawling through posts etc, it seems un needed for under 500bhp now. The 2.1/avcs combo i reckon should work well

Yep. Rotated not worth the hassle/expense unless, as you say, you need to help the engine to breathe really easily for high bhp.

Even the 2.0 can 'easily' make 500+ on a state of the art std position turbo of appropriate size.

OT, but what kind of power band would you get with a 500hp turbo on a 2.0? I might beeping something similar in the future, but I want power from 3k

Good Luck with that one, You`ll probably be more nearer the 4k mark with a 500hp bolt on turbo on a 2.0l, Single Scroll?

Hmmmn, 500bhp on a 2.0 with full boost by 3k.

I doubt there are too many turbos that could achieve that. As above, you're prob looking at c.4k, at best.

But don't forget, never lose sight of the fact that you'll still have raised bhp (and therefore increased torque too) throughout the rev range, compared to a smaller turbo - regardless of spool. Spool-up time (and peak torque) ISN'T everything.
