Best thing you can probably do for reliability is ratchet down your horsepower expectations a bit. The list is long of owners who do these "ultimate" builds with all the happy stuff, and they take years and big bucks or a lot of effort to complete, only to blow a few months later and end it all in tears.

Or you can make 50-75 horsepower less, save a **** load of money, and have almost as much fun for longer. Everybody's use and definition of "reliable" is different, but I don't think there's any magic sauce you can throw into a turbocharged car, let alone a high horsepower turbo rotary and expect not to have to think about it again—unless you add a rotor, you're still working with 1.3 liters.

They're going to blow sometimes, but if you do a simpler build, you're probably going to be a lot less heart broken and be back up and running sooner when they do.

 

Nope, gotcha. Thought you were calling out my post, as it was the second one and the "engine" portion was right about $7k.

I was gunna have to question that, if so, as most of what I have falls in line with what you also suggested

Gotta agree here Peter. Build for more, run less

 

ah ok, i don't see a problem spending that kind of money if you are building an almost new engine with a handful of reliability upgrades internally.

i sort of stopped reading that page when i saw pineapple mentioned numerous times. i also have nothing against them but their line of thinking is far from mine.

 

Hi what are some good internal engine reliability mods that I should do to my engine that I'm going to be building up.
Thankd

 

Pistons...

 

I would never put a piston engine in a rx7 fist they are becoming rare, second why have a rx7 if its not a rotary that is what makes it unique to all the other cars out there.
Thanks

I would think that reliability falls under the maintenance of the car, the components chosen, the tune, leaner tune in cruise, richer tune in boosted areas. don't run anything outside its design/safety factor. run a 300WHP range for increased drivetrain reliability, don't launch the car, etc. let it warm up and cool down properly. lube engine well with 2 cycle engine oil to prevent carbon build up. Do dual oil coolers, radiator and all ducting, keep intake air temps down, ensure only to boost when heat sensor is not heat soaked. Change fuel filter regularly, run a reliable fuel pump, (2) if you want to be super reliable. run highest octane.
