Hybrid Vtech

[mlowe]

Anybody have any feedback on swapping a B16A vtech on the stock 97 B20. I've read about the power gains and seems to be a faily simple mod. Be interested to hear of any problems anyone else has had. Thanks

reliable b20vtec engines cost money

[mlowe]

Yep, but here's my reasoning. Have a 97 CR-V with a 100K, not a bit of problems until recently. Have a 19 ft SeaRay boat I'd like the pull over the hill without feeling like I'm abusing the stock B20 to death. I figure a nicely rebuilt VTEC head, PCM and solenoid might be cheaper than getting a new vehicle to get the extra hp. Pretty dumb eh build a nice little motor just to tow a boat.

Not a good plan. What you need for towing is more torque. Adding a VTEC head to the engine will increase horsepower, but mostly at the top end. You'd have to tweak the valve timing significantly (i.e. professionally) to have any kind of impact on the delivery of low end power.

[mattt]

Varmint is right... DOHC VTEC engines are great for racing, not towing.

I.m.o. you're better off boosting your b20 8 psi. Lots of low end torque.

A B16 is a torqueless little motor not well suited to a CR-V. A CR-Vtec (B series Vtec head on a the B20 block), also known as a Frankenstein motor, would be a better choice as long as the proper mods are also done to the lower end guts. Doing it right ain't cheap.

boosting the b20 would be the way to go. about 8psi would give you the torque you need. dont put a v-tec head on it.....wont help your situtation

just supercharger that bitach

[mlowe]

Had to replace the head anyway that's why I was thinking vtec but I did just pick up a used non vtec head and turbo charger with exhaust manifold that should bolt right up. It's set for a 7 psi boost. Now for my next question is an intercooler necessary for non-racing applications? Appreciate the feedback.

[slick*vic]

it is not neccesary but makes the turbo more efficient.......plus it looks mean as fuck.....lol

[mattt]

with our b20b/z engines, even a small amount of detonation can easily result in craked sleeves... an intercooler will make it easier to prevent this from happening

a used stock intercooler from a volkswagon 1.8t (or tdi) or from a talon tsi is inexpensive and will help make your intake air temperature a little more ping friendly
