I'm planning to build a B20vtec with my first gen b16a but these questions in my mind hindrance me to continue this project..

1. Do i need to use standalone Computer Box and set my vtec trigger to 4.5 or lower rpm? coz i know b20 block can't handle above 7000rpm.

2. How can I strengthen b20 cylinder wall that is capable enought to handle huge rev?

3. If its much better to replace rod bolts? what kind of rod bolts?

4. Do blockguard advicesable for this project?

5. Do I need to change my piston?
Please help.. all suggestions are welcome.. Thanks for now..

 

you could have asked this in your other thread. whatever, i'll try to help. but dont listen to me, i dont know shit. :shhh:

1. yes on the standalone. do not use a piggy back like a vafc. you want something like hondata or neptune. and typically you'll want to raise vtec, depending on what cams you use and other variables.

2. the cylinder walls are not the issue. the rod bolts are unless you use forged rods and pistons. you should balance the rotating assembly to handle higher revs. you can sleeve the block if you still feel this is an issue.

3. if you stick with oem rods you need to upgrade to arp rod bolts and have the rods resized if you want to rev to 8k.

4. no

5. depends on what compression you want to hit

 

Thanks your always answering my stupid questions.. Thanks again ^^
