if i were to use a b20 out of a 97 crv and a gsr gead what would be the approx hp/torque with as much stock internals as possible(without the motor being unreliable) and just a header, exhaust and intake? would this be an acceptable swap for a del sol?

 

just know you would have yourself a high reving engine. All stock internals should be fine (use the b18 crank) just as long as you dont beat on it daily. I have no idea what the hp/torque would be. Dyno it and tell us As far as it going into a Del Sol...anything can be done with enough money :thumbup:

 

not really. you'd be limited to the b20's redline with stock internals. b18b and b20b cranks are the same.

 

ok then would a b16 head on a b20 block produce higher revs???
thats what i heard from this guy I work with. i was just kinda applying what he told me about a b16/b20 to a b18/b20.

 

Hold on a minute... :eh:

1) The head will affect high rpm efficiency, not physically limit the motor from revving.

2) The B18B or B20B/Z internals are kept to a lower rev limit, by the ECU for a good reason.

3) My honest opinion on CRV / VTECs and other Frankensteins is that you're better off buying a B18C and Sleeving it out to 2.0L using the Darton or AEBS sleeve replacements.

Then:
a) add high-c/r forged pistons and rods for an NA build up.
or.
b) low-c/r forged pistons and rods for turbo applications.

Basically, if you want to have a VTEC B that is as reliable as a stock B18C5 (for example), then it is best to start out with a VTEC motor, rather than do things cheaply.

A powerful, reliable small displacement motor costs serious money. It's one of the universal truths in auto performance.

 

right on :rockon:

 

what kind of figures would the 1.8 slleved to 2.0 produce?

 

Amen! Well put:thumbup:

 

Thank you both very much. :cheers:

 

all these what if questions will vary depending on what internals you're using.
