I know there’s Honda V-Tec motors with turbo kits, but I don’t get how that would work because V-Tec motors are designed to make lots of power with forced induction. Plus, aren’t they high compression so wouldn’t a turbo make it blow up?
Do they change the pistons/heads to lower the compression ratio?
It’s all about the tuning and the engine management. The only “problem” with turbocharging a VTEC engine is making the torque curve flatter, instead of ending up with a sudden power spike when VTEC engages. Any decent engine/dyno tuner shouldn’t have an issue dealing with this “problem”. A higher compression engine means more power with less boost. Of course it also comes with a greater risk for detonation, that’s where the tuning comes into play. But the Hondas and Acuras pushing an above average amount of power 400-600+ WHP, have replaced the stock connecting rods, sleeves, and pistons with aftermarket ones. At that power level, people do head work (port & polish work), and upgrade the camshafts (along with valvetrain). But that’s not really for safety as much as just for added power; the head work & cams I mean.
Unfortunately, about half of the Honda owners out there simply slap on pre-made turbo kits and drive without a second thought. Those people eventually do blow up their engines, and get an expensive lesson.
with a stock motor u can run low boost..8-10 psi with a 75 and up hp increase. yes they do have rather high c/r, but its all in the tune an psi levels. no u dont have to change internals, until u want more than 10 psi
if you want a fast car, you made a huge mistake in buying a HONDA

DAMN, thats expencive, for the $4k on top of the $5k for the car I could have me an Audi that competes with a Vette… compared to a Honda that can barely keep up with a RX7
