highstrung? no it wont be high strung. think about it. d15b7 makes 102 stock crank. Y8 head alone brings that up to a calculated 120, just from the headflow characteristics and increased compression,. that cylinder head also has teh best quench pad for VE. a mild cam will net another 5 or so horsepower. what do you have? you have a motor with OEM parts that has similar characteristics to teh stock B7 setup, but it simply has more power across teh entire spectrum
not by any means high strung, and the Y8 head adds about 10 peak torque, and some of teh low and mid range is increased over 15 tq
Im thinking your one of those people that lean towards a swap then to deal with the stock single cam
I think the d series is great for one of two things: either turbo it or just get groceries. Engine building is tedious work and for the cost of aftermarket parts and the time spent in the garage, a built N/A d-series just does not sound even remotely worth the effort to me. And, yes, I consider anything with a 12:1 compression ratio high strung, and you'd have to be a tard to put 87 octane in it. I'm not trying to be a hater, that's just the way I see it.
What do I have? Bone stock 99-spec b20 with a gs-r transmission. I consider this an upgrade from my previous motor, which was a built b16A with BC spec 3+ cams, omni valvetrain, decked head, etc, etc, etc. When it comes down to it, I'd rather have the car go when I hit the pedal rather than having to drop two gears and scream like a banshee to pass a minivan on the highway.
