a friend of mine is looking to replace the busted ls in his da teg and he's considering getting one of these two motors. he will be keeping the stock ls trans. also, if he went with the b20 i believe he would be still running the stock pr4 ecu. now i realize numbers wise they should perform about the same, but i was wondering if anyone with personal experience would suggest one motor over the other.

 

. i would go with either one it depends on what hes looking for and future mods ive had both motors before and both are great choices

 

B20 ALL DAY....

 

ytf this in AC?

 

B20Z for sure

 

b20 more torque for the same price

 

B20... then you can become a member on the gangster website known as b20vtec.com y0!

 

B20 . But change the rod bolts.

 

the b20 would definitely appeal more cosmetically?

 

your friend should replace his busted block with the block im selling

b18b1 with oversized b16 pistons for higher compression, acl bearings and arp rod bolts

 

LOL !

 

just make sure you use upgraded rod bolts

 

ah crap. i wasn't paying attention and just saw honda/acura and was looking for a general place to put a question such as this. was going to just throw it in the integra forum but didn't know if i'd get *itched at for putting it there. seeing as how they frown upon comparing motor X to motor Y type of threads. if someone wants to move this to somewhere more appropriate, by all means have at it.

anywhoo, so i see a lot of people are fans of the b20..
i assume the upgraded rod bolts are really only necessary if you're going to be revving it past stock redline? on an ls ecu do these engines make much power past there stock redline? basic logic would suggest not but i mean i don't know a whole lot about these motors. do many people get chipped ecu's with b20 maps to run the engine, or does everyone just use the pr4/p75?

 

i'm in the exact same predicament with my integra so i'd love to hear more input..

 

B20z more torque from a idle.

 

I love the pull of my b20

 

X2 also had both b20 over b18 unless your plan on one day making big power on the motor with a build.

 

why is this ??
