Well I know the head package adds about 75bhp so with the compression increase and the prerequisite bolt on's you should be seeing about 250bhp maybe closer to 300bhp but no more. Basically you'd have I/H/E/Head/Cams/HeadWork/ECU...so heres the math:

(All Flywheel numbers)
Baseline-160
HeadPackage- +75 = 235
I/H/E- +30ish = 265
With appropriate tuning you could see higher gains.

For anybody questioning my bench dynoing:-) You have to understand the Head Package from Gude as it is cams, headwork, valvetrain upgrade, valve grind, porting etc. in one package. Thats how the one item adds that much power as it's a combination of a lot of work listed as one whole deal.

So assuming everything is tuned correctly and you upgrade the suspension, tires, and drivetrain accordingly you could probably dip into the high 13's as long as you drop some weight of the car (ie- remove sound deadening, carbon fiber hood/trunk lid/sunroof etc.) But remeber 13's are pretty fast for a fwd car like ours...I've seen LS1 Camaro's run in the mid to high 13's with exhaust/intake at the track with not so great drivers and stock tires...and those are rwd cars designed for that purpose.

For comparison, the E36 style BMW M3 runs in the low 14's high 13's stock and it has 240bhp, however the gearing is much more aggresive and it has a significant traction advantage because of the amazing suspension setup and rear wheel drive. You would need to modify the suspension in order to let your front wheels put all that power down as best as possible or else you wouldnt run as fast you'd hope or think...but regardless from a roll your car would be quick. From a stop however you would be at a distinct disadvantage as fwd is not ideal for drag racing.

Umm...I hope all that made sense? lol.
