I see your point.

but where not talking about a new enigine.

It sounds like it just getting worn.

that's why race car's have catch cans to spit out water and other s*!t that gets in there oil.

i'm not saying to get a catch can but maybe a breather would help.

I know in sa you can't even get 13b engineered.

so i'd say no they won't let you get it registed.But you mite have some luck.

talk to dattoman 1000.

it's a bit hard to tell you not knowing the full story.

did you get rid of the pinging ?

that is the longest thread i have ever seen.

god dam!

speak to dattoman 1000 and also look at his web site it will tell you everthing you need to know.

with what your talking about doing you should get over 200 at the flywheel

The ones i am telling him to use are double springs.

120fly is right i'd tell you to use crow cam springs.

the product number is 4220.

good luck

looks like it just needed more fuel and going up to a higher gave you a better mix.
or it just stop all together.
