hey, what up? i know a 20b swap isnt a chead or easy thing to do with a fd, but i was wondering something.



how much more does a 20b weight than a 13b??? does a 20b into a fd really mess up the great handling of the fd???

my car lost 60lbs when i went back to a 13b

 

you had a 20b and went back to a 13b? can i ask why? was it for handleing?



i am suprised the 20b only weighs 60 lbs more than the 13b, that really isnt to bad and i wouldnt think 60lbs would throw off the handleing to bad.



hey the RE gt300 uses a 3 rotor and jgtc cars need to handle real good.

 

I've heard on other websites that the 20b can actually shed some weight, any truth to this?

Apparently the 20b pushes the steering rack to a different location which causes bump steer, which would affect the handling somewhat. To be honest I can't see how this couldn't be solved with a new rack - it's not like the 20b guys are on that tight of a budget

I compared the weight of a 20B almost literally part for part to an old style 4 port 13B from my REPU and if I move the battery to the back, my front end may just about break even. I could hardly believe it myself. Of course I am not using the stock twins, so there's a weight savings on 62lbs right there. Infact, my header weighs the same as a stock 13B exhaust manifold from an R5 (JDM Luce or Cosmo) engine. Both weighed 21lbs or so, yet my header shifts its weight much further rearward for less weight directly over the front wheels.

 

so even with a 20b, the fd would still be one of the best handleing cars out there huh?

 

So long as you don't have to get rid of your front sway bar, sure.

 

You'll still have the bump steer problem though..... the only real solution to that from what i've seen is moving the engine/tranny rearward....

 

Even though it's a full blown race car, the RE-Amemiya FD with the 20b seems to handle pretty well...Of course they have a bigger budget than most anyone dealing with a rotary.
