First off i have a 91 240sx with a SR, it's a plain bone stock sr with a full 3 inch exhaust,FMIC, 255lph fuel pump, BOV and intake.
I recently ran a compression test on my red top sr. The numbers were not all that great, so I was looking into a rebuild. It just so happened that my buddy got rear ended so he's parting out his car (s14). He just had the motor built about 1000 miles ago, and he's only asking $1000 for the bottom end. It's a redtop sr with forged internals and .040 bored over. So my question was can I swap out the bottom ends without having to get it tuned or run bigger injectors,etc.
I've built a few SRs but all of them had turbo,cams,fuel upgrades and had some sort of engine management with them, so of course they were all tuned.
Any help would be greatly appreciated.
