is this your motor for the supersprints? the one you made a p[ost about? or is this anotehr one?

[Benson]

Yes this will be motor that will be used for this year supersprint. The B18c had a set back so that will be finished mid this year. The B20 is just as good, if not better

i think this thread would be mighty relevant so i ask....


does anyone have a dyno sheet of a blocked cat? doesn't matter what cams it has... it would be interesting to see what the powerband drop off is like....

***DSP26's notes***

after spending $XXXX amount to get my car running, I understand now that those who were saying get a better Final Drive ratio are correct as it moves the entire powerband across to the left. Only reason i don't regret this build was coz my engine needed it... but in terms of first performance mod, final drive is better!!

I just discovered my gearbox has had a 4.266 final drive all along The gearbox is a Y21 aswell so thats odd.... Its funny considering how torquey it was for a b16 and how well the car went for what it was.... Would of been interesting to see how it would of went on what it was suppose to be (4.4 FD).. oh well ill never know.. i upgraded to an Mfactory 4.928... we will see how it goes.. im excited

how did you get that? or all Y21's have it? i'm guessing for JDM/AUDM version... coz the american online calculators have the Y21 as 4.4fd

[delsol9000rpms]

dont ask man. There are rare y21 gearboxs which come with 4.2s but ye thats very odd
