well another big reason i can see going with the SR over a rotary, is becasue of knowledge.
its much easier to call up a nissan guy and say i can't figure out why its doing this and they say well you have to do this
but with the rotary it takes a specialized mechanic to work on it and a really expensive one if you want it to last, thats the reason why its cheaper to work on piston motors is because of knowledge, there is just alot more of it versus that of a rotary
i'm swapping my rotary out for a piston motor, becasue i want something familiar under my hood, and i don't have the money to blow on learing and experiminting with a whole different kind of machine.
now i love rotarys, and have tons of respect for the people who build them, but personly i don't know nearly enough about them to start makeing big power with them. but i have built several 300-400 hp SR's and several high power inline 6's
(RB's and 2J's)

correct untill i come up with a very small pump and custom make lines wo adapt the sr to the new rack. i plan on doing this soon enough but for now the fd rack unpowered is actually rather pleasant from what ive experianced in the past.

why get a piston engine, when you have a car that a rotary engine will bolt right into, the car is even designed for a rotary engine! as a matter of fact, it is the only car in the world that is sold with a rotary engine already in it!!!
High CoG is very bad for handling!

WELL i went with the sr over an rb mainly for weight and size differance..even though the two engines share the same displacment the rb is still much bigger than the sr. not to mention the sr is supported way more by the aftermarket and is way more user freindly to me, im not trying to build a dyno queen here. as far as why i didnt put in another rotary i have gone over that many times in this thread.

It makes sense to me for a few reasons, 1 because i can, 2 because my renny died with no waranty and i wasnt about to spend more money just to have a stock problimatic power plant. so i can deal with the sacrifices i have made. plus the 8 looks and drives way way way better than a 240.
i like the idea of you engine swap.. just curious what tranny are you using i dont know much but i believe there is a 5 n 6 speed tranny? also are you doign any internal work? for your 435 goal is the tranny/ motor strong enough to handle that kind of power? (or after market parts required)

i wish someone told me that before... i already have a brand new runnign remans but im lacking desirable power. i refuse to boost the rotary again. im stuck between selling the 8 and changing cars or doing an engine swap...... which means i wasted like 4g on putting back the remans when i sholda just swapped a new engine. so many bad choices in my life.. hahaha

The RX-8 is so perfect, it has it's problems, but the actual design is really good.
This whole thing is just disgusting.

Quite interested in seeing if there is any performance advantage over just putting in the MazdaManic Greddy turbo upgrade for our rotary engine. Please do a dyno when you finish. The comparison would be very interesting.

Agreed but I still am a fan of the SR and the REN so I'm excited to see results of any sort!

i will post up slips for sure. just keep in mind that the only real performance mods im starting with are pretty basic. were doing a full custom 2.5" exhaust that is going to be almost straight through, acompanied by 2.5" charge pipes mated to a srt4 intercooler toped off with a greddy type s bov. no ac compressor and now pws pump. a apex i super afc, hi flow fuel pump( not sure what to buy yet) with all hi flow stainless lines, and i wide band to tune it as much as possible in its stock form. the ecu has been reflashed by central 20 racing and is kind of a pain in my *** because i cant get any specs on it. It came with the engine so im going to use it and see what comes out of it. were hoping that my base whp is some where aroung 210 to 225. im not going to have this thing pushing retarded numbers till we get it driving again to work out all the inevitable kinks that are going to come up. none the less i will post up sopme slips.

There is actually a large performance disadvantage by using a sr20det as opposed to a MazdaManiac Greddy setup. First, the turbo'd renesis is more powerful and second, the sr20det car is going to handle a good bit more shitely.
