Trans... Well, I have an LS trans on a GSR motor with a GSR clutch because I highway race so I want the higher top speed not so much the low end giddy-up. If you plan on circuit racing, go with the GSR trans with a 4 or 6 pad clutch (stage 3 and stage 2 respectively) so you can git her going after the apex.
Tell you what, my low end acceleration could use help, but I might go with a throttle position sensing setup to fire up a 50 shot at WOT to fix this cuz I like my LS trans too much.
1. The compression ratio of the B18C5 is not too high for boost. It's all about fuel and tuning.
2. The LS will hold up to just as much boost as the B18C1. So if you're going to eliminate VTEC, why spend the extra money? Besides. All of the VTEC killer cams are high in lift, but also have long durations. This is bad for boosted vehicles, because the valve overlap is too great, causing the motor to bleed boost.
3. For 200whp, you can run stock internals no problem. I'd recommend ditching the fuel setup that comes with the turbo kits, and getting some bigger injectors and a hondata for tuning.
4. As for clutch, you'll be fine with a full faced ACT clutch. Going with a 4/6 puck clutch on a daily driver isn't so great. The engagement is very harsh, and the pucks like to break off.
5. For the 50 shot you want to run, make sure it doesn't come on before 3500 rpm...or you'll risk grenading your motor.
