Viewing a discussion on Bring A Trailer, someone chimed in and said you get an easy 400-450hp with a LS engine swap, but 250hp in a Datsun Z or 300hp in a 944 is an absolute riot (I know as I own both) and our streets are so crowded anymore there is absolutely nowhere you can use 400hp let alone 450hp or more...and who has time to go to the track anyway?

Other than some meagre bench racing bragging rights, what the real advantage? I don't think its maintenance as Datsun parts are inexpensive, 944 parts aren't bad either..and personally I prefer the nostalgic sound of bridge ported rotary in a RX7.

Your thoughts?

I've got to think that SBC parts are still cheaper than Nissan, Mazda or especially Porsche parts. Many/most folks end up wanting more power. You should be able to build an LS3 to be cheaper, faster AND more efficient (there are folks with Vette's that are getting over 30mpg). Not to mention, a new LS3 could burn cleaner (better for the environment) and they do sound really good.

If you've got something really special and numbers matching, great, keep it special. If you've just got a cool old car, then have fun.

I wouldn't do it to an authentic, original '73 911 RS or an old Ferrari or a Jag E-type.
