Weight of the 20B, weight of the Renesis??
I have tried unsuccessfully to find these two numbers anywhere online. Does anyone here know the weights for both the completed Renesis and the completed 20B-REW??
How much would a 20B swap affect the handling of an RX-8? I'm not considering the swap, I don't have anything close to the money, I'm just curious.
Thanks

Renesis is about 260 lbs.
20B is something like 400 Im not 100% sure.
If you try to fit a 20B, you have to cut the frame, which means there is no going back.
As for affecting the handling, well, unless the owner of the car is a moron, Im sure the person will upgrade a lot of things, so handling should not be a big problem.
The swap will cost a lot of money even if you can do it yourself. and I believe such swap is 100% illegal in Most US states.

Also, why would it be illegal? I've seen many post about people doing it on here before. Is it due to stricter emissions requirements??

not to mention 20b is not even a production engine designed for street use.
If u're in CA and cops wanna see your hood and they KNOW what 20b looks like, u're screwed, they have the right to tow your car.
with 20b, you will be giving up almost everything you have for your RX-8, since your ECU not going to work, you need to have custom engine management like Motec, then the location of the engine changed, your whole drivetrain needs to be change, etc.
A lot of money and time if you ask me. Is it worth it ? probably, if u're doing this as your project car. but no matter what you do, it will never be street legal.

because in some states, its illegal to swap any engine thats older than the one you have for your car. You're only allowed to swap with the exact same model of the engine.

If I ever did attempt this project I would be doing it from the ground up.

not sure about Illinois law so you have to check that out on your own. Even its legal to do so, you might want to make sure your car stay in Illinois, cuz who knows what happens when you go to another state ?
oh also, if an accident occur and your insurance company finds out about this (the engine thing), they have the right to deny your coverage. thats something you might want to consider.

the 20b-rew cam in the japan only eunos cosmo. they built it from 89-95 or maybe early 96. it was never certified in the us, and thus is technically illegal in a roadgoing car here.
the weight of the 20b is a lot, its got all the complexity of the FD-rew engine, plus another big iron, rotor, rotor housing, etc etc
a stripped down 20b, with stock turbos, no emissions or turbo controls, is about 60lbs more than a 13bt. my car went from 2860 with the 3 rotor to 2800 with a stock 13bt

no cop that asks to see under your hood is gonna know what a 20B is. and if he does, he'll probably drop to his knees and cry because his life is worthless without the 20B. even if one does ask you to pop the hood and recognizes the engine, hes not gonna know its illegal. its all gravy.

Eunos Cosmo production was 90-95. To my knowledge, there are 3+ certified, titled, registered 20B-REW powered Eunos Cosmo's in the USA. Plenty of hoops & red-tape to get these private cars on the road, trust me......

Its 20B-REW uses metal intake manifolding. Those twin turbo's weigh near 50kg alone with manifolding. Although it seems high I must admit I researched this info via Google. Personally, I would have expected 250kg - 300kg bracket but the explanation I read appeared reasonable so I went with it.
The 13B-MSP engine uses plastic intake manifolding & its exhaust manifold is less than 10kg

thats nearly 800 lbs!
for a rotary? arent they supposed to be light. a fully dressed chevy v8 ls1 weighs 500 lbs. (226kg)
how can it be true to its small and light rotary heritage and weigh more than a v8?
1600kg = 3500lbs
