2nd b20v build for me and so far so good. What do you guys think of my build and how much power should I be putting out. Just to get it clear theres no dyno where ever I live so thats the downfall. Heres whats on the list.
B20b stock bottom block
B16 ported head
blox dual valve springs
CTR both intake and exhaust cams
skunk intake manifold
cheap *** fuel pressure regultor but not ebay
skunk2 cam gears
msd cap with exterior coil
Phearable b20vtec map with p28 ecu
For now its stock throttle body but will be upgrading to 70mm.
I want to get a thinner head gasket bump up the compression a little higher.
Future for the block is at least b20z pistons and arp rod bolts.
This is a mild build and my wallet can only fork out little by little. Any comments on tuning
will be greatly appreciated. Please dont flame on me and start bashing this thread. Thanks

 

theres countless B20 threads out there and ones with stock bottoms make about the same power. Look around and search what other builds have done.

 

You dont list a header. BUT, you should see around 190-200 whp pretty easily with that setup. Any more than that would be just a guess.

 

Stock bottom end with stock pistons?

 

Oh my bad I forgot. I do have header. 4-2-1 hytech replicas

 

sad to say but yeah stock bottom and pistons. Our gas here sucks ***!! highest octane is 91. I was going to the 11:?? comp ratio but our gas goes against it. I wanted to upgrade to at least the stock b20Z pistons which has a higher comp ratio than the b20b's.

 

Not trying to scare, but I'd be worried about p-v.

 

i was thinking that myself. is the lift on the itr cams enough to cause an issue? does it just turn into a clay the bad boy and see what it looks like situation. i would spare the money spent on say a msd cap and bigger tb and spend it toward some tuning


semi on topic, but did the b20s that came with p8r heads have larger valve reliefs in the oem pistons that can accommodate the vtec sized valves with any cam that has moderate lift

 

Cams aren't that big in the P8R b20B heads, valve reliefs are still small.

 

I'd check. The exhaust side can be problematic.

 

Piston to valve clearance isnt a problem at all. Weve been playing around with the cam gear degree and its just doing fine. My real problem is tuning. I have no real idea what to do when tuning.
