[MrodDrft]

Thats some GREAT info but im just wondering how is it easier to swap in a RB26dett than to swap an sr20 ?

[killab18]

yea also on your scale its easier to drop in the vq35de in the 240??? you might need to change your difficulty ratings. But damn good info reguardless.

[metalmulishaS14]

ALright, I have a 1993 240sx, with an s13 sr20det. How hard would it be to put an S14 sr20 in it? Im thinking of buying the whole front clips, so that may help... thanks
