Ok, here is the situation. I have a built B20 bottom end that is just sittin in my garage. It has eagle rods and JE pistons (pretty high comp, pictures posted below). I got this block before I went turbo (I know, I know, I'm one of THOSE guys......) and ran it once before I knew much about anything. It ran like shit (cause it has such high comp and was never tuned) so when I found a good deal on a gsr I dropped that in and went turbo. Well, my turbo car does 325whp @ 11psi and runs a shitty 13.1 @ 118 in the 1/4 mile (on street tires, and my first time at the track, dun shit on me to bad pls).

Question 1:

Should I sell the B20 block or rock it? I know that I need to get the thing clayed so I can figure out exactly what kind of clearances I have if I run it. But in the end is there a point in running it when chances are my current car/engine combo is faster? What kind of power might I expect out of this thing (supposing a stock gsr head, stg II cams, decent exhaust header and skunk2 intake)? I know its guesswork, but I am just tryin to determine if you guys who know about this shit think its even worth it for me to play around with this thing.

Question 2:

Can someone give me a good method of determining what the cr is on these pistons? I would search but the search function is not currently working.

TIA for any suggestions..........

why need vtec when you have turbo. the whole point of turbo is to not run vtec. why have vtec when you can run vtec all the time. which in term no vtec. why would you wanna run the low lope and then the high lope. just run high all the time. unless you wanna save gas then that's another story... plus you won't have to worry about the switch over point, specialy when you have the turbo.

well i think u know the answer if your posting this in the all motor forum lol. anyways i think you should keep the turbo if everything is running fine, then if it blows up go all motor with this block.

judging from the dome on those pistons im GUESSING theyre 12.5:1 or even 13:1 CR

and if your going all motor get the head ported, and a big throttle body. the b20 likes to breathe

If you do decide to sell it, hopefully the buyer knows its super high comp and was driven on without being tuned.

My guess was around 12.5:1 as well. Thanks for the suggestion.

Yea, I would mosdef let whoever know that. It was only driven ~50 miles untuned. I never really got on it cause....well it ran like ass even @ partial throttle. I'm not the type to push something thats not working correctly. I would wager being driven gingerly while untuned would not really hurt this block though.

Oh, and if the buyer doesn't know this is pretty high comp......he's in more trouble than I can help him with. But I would of course tell him. Lol.

Anyone have a good dyi method for cc'ing the pistons?? It would be a good idea if I at least knew the cr.

ya know, i never tried this or heard of it before BUT its an idea i had while reading this. so i figured ill pass it on to you.

if you took a bunch of playdoh and made like a big ball of it, then mushed it down on top of the piston. therefore making an impression of the piston. then take a syringe and fill it with water up to a certain amount of CC's then fill up the impression of the piston you made. and see how many CC's it takes to fill it.
