Pecivil,

Are you going to the S.D. auto-x next weekend? If so I'll have to seek you out so you can show off your new hot ride a little.

Did you get any dyno results, maybe before and after? Or perhaps how much you paid for the conversion and where you had it done? All us jealous non-3.4-ers want to know

I haven't dynoed it yet, I will pretty soon, probably the next dyno day through PCA or BMWCCA. It feels so much more powerful I am dying to know what it puts to the wheels.

In terms of the cost, it ended up costing more than I thought it would. But I had unplanned expenses, like needing a new clutch and flywheel.

Cost breakdown:

2001 carrera 3.4 31k miles - 7k
Instant G headers/100 cell cats/muffler 3k
clutch kit $400
AASCO Fly $790
996 Throttle Body $250
Various hardware $250
labor about 4k
so a little under 16k

Got it done at Mind over Motorsports in San Diego. They were really good. It took awhile, but they were very professional and did a great job.

I'm guessing your about 270-280HP at the wheels.

SPortec put a 997 3.8 in the 987 Boxster (aprrox 350 HP) and Excellence said it could have easily handled much much more.

THe car definitely comes "alive" out of corners when 250HP/Torque or better is under there. I've driven various roadsters between 130 HP and 300+ (I forget what the Dinan MZ3 had) and there's definitely 'sweet spot' in the power to weight ratio.
Most well balanced roadsters handle superbly like a land shark with less HP but a roadster of roughly 3 tons at 240 HP and better has an extra kick in the pants.
My local autocross club put the 986 BoxsterS in with the 3.4 and 3.6 911's.
I've equalled or bettered them on many ocassions. The 2.7 Boxsters on about 20 less power than the 4 cylinder S2000 go back and forth for quicker times. The M3 coupes seem to post similar times to the standard 996 anbd 986S.

I think what you feel is that crossing over that sweet spot (which really doesn't affect peformance as you see with the S2000 match up) but changes the seat of th pants feel entirely.
Kinda like a 3.5 - 4.0 ton coupe when you cross the 500 HP in straight acceleartion. 350 doesn't feel much slower than 450 but over 500 and it's like "wow!"
