Ok, my friend and i are arguing the differences in motors, moreover, which will do better mounted in a 1st gen CRX. My argument is that the weight difference is totally negligible, and that the power difference is worth it. His argument is that vtec takes away from the power/torque curve of a non-vtec motor. Any thoughts guys?

btw, if someone happens to know the weight difference, id appreciate it.

 

up. i know you guys love to argue.

 

Well yes you would be right, the weight difference between the two motors would be next to nothing. The jdm D15b has about 20hp over the d15a3 you're comparing it to. I dont know what you mean though by vtec takes away from the power curve of a non-vtec engine. Are you talking about putting a d15b head onto a non-vtec bottom end?

 

Thank you!

My friend seems to think that the power/torque curve of a non-vtec engine is biased so that the vtec engine makes less usable power and torque over a non vtec motor. this makes no sense to me, but i have nothing to back it up with other than "your dumb."

Does anyone have the weight difference somewhere? Thanks!

P.S. this is all based on the idea that a 1st gen CRX will do a little better at local auto x with the d15 rather than the d15a3. have at it.

 

anyone

 

The D15b will dust that other one. Weight difference will mean nothing as opposed to power difference.

 

you do know that a D15B will not bolt into a 1G CRX without fabricating all new mounts and using the 88 and up D-series transmission?

 

aha! well thanks! does anyone have a popular bolt in motor that would do well in a first gen CRX?

if you wanted to purchase a mount kit, axles, shift linkage, etc. you can also swap any B-series engine into it

if the CRX is not the Si model, you need to swap out the fuel system and most of the wiring for ones from an Si model

 

wow, thanks so much for that information. My friend was kinda right. This makes me want to pick one these bad boys up as a prioject and do a restoration. Either way, lots of good stuff. Are there any vendors that sell a motor rebuild kit for the stock motor?
