Does anyone know the bare engine weight (no manifolds) also the weights of a series 4/5/6 13B's would be good too.

I'm considering installing the 20B into my FC, but am wondering what will it shift the weight distribution to? as the factory 13B setup is nearly 50/50.

My car is only driven on the weekends and about once a month at the track so weight dist is pretty important to me. I have considered the 20B route as it would be more reliable for me in the long term as a low boosting 3 rotor compared to a high boosting 2 rotor.

Any comments would be much appreciated.

 

I all depends on how you build the car. You need to check the applicable racing rules to see the minimum weight allowed for a 20B RX-7 in whatever class you will be racing. If it helps any, here in the US, a GT1 RX-7 with a non-turbo 20B has a minimum weight of 2100 lbs.

 

Sorry. What I should've said was that it is only on the track open days (i.e. you only need overalls and a helmet)

If I could only afford to race in a season

So its pretty much a street car.

 

What the hell?

Interesting two people at work use this site

 

I would guess around 150 lbs. Me and one other guy picked one up off the floor and put it on a cart. Not that scientific and I haven't been to the gym for a while. (nothing recent to reference)

 

well i didnt wiegh the engine but my 20bfc weighs within 10lbs of the listed stock wieght of an 88 t2 (mine is an 88), mine wieghs 2860lbs with a full tank of gas.
the engine is further forward and you will feel a difference, but it seems to only feel different

According to Peter Farrell, the difference in engine weight between a 20B and a 13B-rew is approximately 100 lb.

In my car, I have a 51%/49% weight distribution. If you haven't already seen it, look at www.cris.com/~Asam/20B.html

BTW, it's for sale.

 

how much you asking for it?

 

$39,900 and I'll consider taking a trade-in, if that's an issue.

 

40k?



Wow.... how about a Schwinn mountain bike... umm...a Super Nintendo... and a sock full of quarters?



J/k man. I'm banking on the fact it's worth every penny and more, though.


If I had the forty g's, I'd be getting this done NOW

I wish I could buy your car, as a 51/49 20B would be the absolute shiz. But I live in New Zealand. A fair way to ship your car and the fact that I could probably build it cheaper being the land of jap imports and all.
