Can u make a CA20DET from a CA18DET?

[phoenix_fire180SX]

I recall Nissan made a CA20 engine in the CA series so I was wondering, how plausable and realistic making a CA18DET into a CA20DET is? Maybe you could take the CA20 bottom-end and somehow get the CA18DET on the top (I got that idea from hearing RB people making an RB30DET from a RB30 block and RB25DET parts)? Just a thought. And I'm also aware of boaring out the block and stroking the engine to do this, but I'd like to keep (make?) the bore and stroke equal, and I'm not sure what that costs anyway.

The main reason I ask is because I'm seriously considering a CA18DET over an SR20DET (mainly for initial cost reasons), but the SR20DET makes more torque, and I like my engines to have a fair amount of torque to go with the horsepower (unlike Honda engines, or most Honda engines anyway). Put simply, I prefer flatter torque curves when possible. I actually like my KA24E because it doesn't lack in torque, but I don't like how it dies after 5500RPM either.

I recall NICO making a search button in the forums. i was wondering, have you used it? Maybe you could, and you would see that this subject has been gone over several times.

The main reason i ask is because if you took 3.7 minutes to read through some posts, you would have found one from just a few days ago discussing this.

ok guys, i dont flame often, so let me enjoy it before you call me an ***, i already know i am. now flame on.

lol be nice to the newbs :pface

just look through some of the old threads... there are a TON of them asking this same question, and its not as simple to make a CA20DET as one might thing... although s13240sxdrifter seems to think its easy as pie

anyways, welcome to the CA forum, and don't let ca18datsun510 discourage you from asking questions (just make sure you search first!):)
