Best Turbo for 2.1stroker aiming for 500??
What is the best turbo to go for on a built closed deck 2.1 stroker engine? Heads and cams are V3 sti Type R, looking for around 500bhp and anything over 400lbs/ft torque will do with minimal lag, any ideas?

This is a first graph from our own stroker. This Turbo Technics S206 turbo is rated at 500 bhp, and we expect to see that soon, having made those figures with the same basic unit on a number of Evos. We should be back soon with the latest version of this one, which will come in at under £1000.

It made full boost (1.6Bar) at 3600rpm on my cammed 2.35
At a guess, i would think it would do the same on a 2.1 at about 4000rpm.
As for lag between full throttle gear changes, there wasn't any on the 2.35

......K8ller - this will be pretty quick spool up.

Still deciding, that S206 sounds intresting just worried that it wont be as responsive as I'd like the car to be as its a daily driver 
Seeing that Alan Jefferey is building my engine I may go for his turbo but really need to see what the spool is like, the rotated GT30R would be ideal but then theres the extra cost of the rotated up and downpipes and bracket fabrication for the turbo, there's so many choices !

Don't go rotated! There are soo many good standard fit turbo's out there at the moment, if the choice of turbo had of been around when I went rotated I doubt I would of bothered. Its only worth going rotated if you want to really make over 600bhp

Will this make a garunteed 500bhp on vpower on my setup provided I have my fuelling uprated to suit?

).
