Buy a shell for $6K-9K. even cheaper on ebay if you find one without an engine. and put a Cosmo 3 rotor in ($5K) for instant 320 hp. Upgraded turbo kit and engine managment plus all neccesarly add in like oil coolers. probally run you another $5-6K if you have fun and do the labor yourself.
instant 500 hp very reliably because they actually sell a 500 hp 3 rotor cosmo engine RX7 with full warrenty from Banzai racing. There been peopel pumping out major HP from a 20B...look at ACosta racing and the 800 hp 20B RX8.
Its plenty reliable since Rolex and grand am class race a 3 rotor RX8 with 350-400 hp non stop for 24 hours. Engine on either car did not blow once so ever. Only cooling and transmission problems. Cooling is the most important part. tunning a rotary is very different from a piston engine. exhaust gas are hotter and oil is the life line. theres alot of idiots pumping out 500 hp with stock oil coolers.
you have a 2800 lbs car with 500 hp compared to a 3500 lbs car with 600-700 hp. Reality is the RX7 wont experence tracktion problems. 500 hp RX7 is a very fast car.
AS for me...im not into drag racing so I would tune it for 300-400 hp. Plenty are reliable at that range. my friend FD has been tuned on 450 hp for 3 years with built aviation seals.
You have to remember that the car is deadly with 300-400 hp. Whos the new tougue king in Best motoring? The one that beat the 800 hp MCR skyline? non other then RE amemyia RX7 on stock turbo 13B
REliability is there...remember that Mazda races rotaries in endurence races. winning 24 hour at Lemans in 1991...not one single break down and virtually no wear on the engine. it just take a person to know a rotary engine to tune it right. And Mazda also has its own formula alantic race car series called star mazda...everyone races a stock renisis motor. And the autox winner here at MArtin morotsports in the street mod stock tire class is a RX7. plenty of people race RX7s so thats why parts are cheap. If you been to 24 hours at daytona you would know that a daytona legend is a Savanna RX7...which won 24 hours at daytona several times and did very well in its class. that was a race program between racing beat and MAzda.
