My motor is just about done being built with the exception of head assembly. I am running 13:1 compression, and have new Spec B's. But have been told that that is too much compression for the B's. Is this true? Only got the spec B's because I got an amazing deal on them. But have been wondering about this so called problem for awhile now. Really am looking for a set of Jun 3's. Actually am willing to trade the new in box spec B's for a set of new or slightly used Jun 3's. Anyone up on that offer? I know this isnt the classifieds, but since I am a trial newbie user I cant acess the classified section to put this up! NEED HELP!!!!!!

 

Get rid of the Toda B's and buy my JUN 4's

 

Hmmm.... maybe interested. what are the specs on the 4's? Also what condition are they in? How much more agressive are they than the 3's?

 

jun 4's are pretty crazy IMO.

 

so how do you get over the valve to valve contact at 0, 0 with jun 4's? did jun just machine them wrong?

You can run the 4's with adj cam gears.lol even with .5over valves. The problem is, there's like 5 different cam gear setting total..lol i have them written down at home from when we measured them in MY motor.

And whoever said you cant run toda b's with 13.0 cr is crazy...I ran toda b's in my 13.0 motor and put down 220whp with minor fuel curve changes and no timming tunning. Spec c's would be a better choice , but the b's will work just fine.
Here's a link back from the old days..lol
