lets say there are 2 rx7's with stock motors and stock turbos. one car is modded with all the (proper) bolt ons running 10psi and the other completely stock. if both were driven just as hard as the other..... shifting at the same rpms, going through the same driving conditions....







which motor will give up first? stock or bolted?

rfreeman27 12-01-2003 08:02 PM

The engine with the bolt ons. Even though the boost is the same, It will flow more air. More air and HP genrally means lower age for rotaries.



good question, that is just my poinion and it could be wrong.

would all the mods make reaching the same rpm and power with less strain on the engine components?

FikseRxSeven 12-01-2003 08:15 PM

replies from teh rotary gurus would be great!!!



judge ito? boostn7?

The higher the boost level the greater the actual force onthe moving parts of the motor. Thus higher wear on said parts over the given time period.

I would think that the motor with more power would fail first. My reasoning is because my n/a making 150~ has 250,XXX+ miles....on the FIRST engine.

I'm going to bring up the heat side of it, especially in a fd; if you can remove the heat out of the modded engine then it should last longer or at least just as long, when done right
