RX-7 w/ RX-8 Renesis Rotory Engine?
Anybody think this is possible? I'm trying to look for more specs on that engine in terms of dimensions and such becuase I'm thinking of giving it a go. :confused:
Granted the RX-7 stock engine has a faster 1/4 time than the rx-8, isn't the rx-8 slightly heavier and all? I'm thinking that in an RX-7, add a turbo, intake, straight pipe, exhaust, intercooler, street ported, blueprinted, larger injectors, higher voltage plugs and wires and I'll be passing up vettes, vipers, and porches at will with a blip of the throttle with confidence that the renesis is more stable and reliable than the stock engine.:D Please let me know your thoughts. I'm trying to obtain as much input as possible before I end up blowing money on a shell and an engine (the engine would be a direct import from Japan of course).:cool: |
There's other threads on this. Ultimately, oyu'd do better with a V-8 that trying to cram a Renesis in there. NO TORQUE!!!
|
Well then in that case, if the admin can delete this post, that'd be great.
I'll just work on doing a search. |

but isnt the whole problem with forced induction of rotaries is the fact that as soon as you do it, emissions and reliability take a nosedive? And i bet those side exhasut ports come out of the block at weeeeird and funny angles n stuff.:eek:

i heard there is going to be some trouble putting a turbo on that engine...anyone else know about this

RP will be doing this soon I'm sure... they are getting 2 of them

Plus it has "colder" exhaust output which won't spool turbos as well (source: Rob at Pineapple).

I also heard something about the compression issue (too high?).. So that putting a turbo will almost mean, bye bye engine..
But when you think realistically, getting a renesis engine, getting custom turbo kit, and all.. it will be cheaper to just go with ported fd engine with single turbo.. it might make more power.. and proven to work.. |

Compression's too high to get any decent boost. |

The ideal form of forced induction for the Renesis would be a low-boost supercharger. Turbo's really don't work that well with the design, for the reasons mentioned above and also due to them causing slow catalyst lightoff. IMHO, the best application of the Renesis would be as it is in the RX-8 but in a small, lightweight car like the Lotus Exige.

do the V-8 swap, much more worth it in the end

Oh uh...a V8 in an FD, that would just make the refined RX-7 sloppy.
|
That's just stupid! Unless yer frum the hills of Arkansas, ya shtupid redneck!

Originally posted by skunks how so? would having double or possibly tripple the amount of the torque as well as hp a rotary puts out n/a not be fun or relible? ok, so it adds a bit more weight to the car but could you tell the difference? I doubt it! I know I could not tell the difference. (I know some people with heavier sound systems in their cars oppose to a V-8 haha).

Originally posted by GoodfellaFD3S It's the principle. The rotary is the soul of the RX7. I'd rather have 400 to the ground out of my BNR-turboed 13B than 600 to the ground out of an L88. Nothing against 'em, just keep the damn motor in a Vette :). To me, if it doesn't have a rotary, its not an Rx-7. BTW: Thank you for defending our country. you have my respect. |
