ok just about everything i read about curb weights of 1st gen rx7's says that gsl-se's weigh about 300lbs more than the other rx7's. where is all this weight coming from? is all the extra weight from the 13b and its components? thanks in advance.

well 13b is heavier than a 12A, the trans is beefier, power steering, some have leather, power windows, etc etc etcc

fuel injection system and that whole 6 port actuation system, sunroof, leather, PS, A/C, bigger brakes, bigger engine, rear wiper, etc etc etc..

I'm sure if you add up all the little things it's there..

I don't have PS, or leather, umm, or A/C(anymore)

yeah I forgot about the 14 in suspension and such, the intake system is way heavier as you mentioned

basicly all the weight came because of the FI sistem, more wiring harness that the 12a, and the 13b engine. plus little stuff like bigger brakes and PS if you have it and 14" wheels

according to the UK brochure the 1984-85 RX7 is 2392lb's

a UK spec 84/85 RX7 is basically a GLS-SE with a 12a engine, no LSD and all the extra's as standard + rear seats + a non catalyitic exhaust system ( no emmissions regs on rotarys till '87 )

according to here http://www.rhinoracing.com/stock.htm

the GSL-SE has a stock kerb weight of 2590lb's

I doubt the rear seats weigh much if anything over storage bins and metal reinforcing so I guess that means a 13b with fuel injection weights about 198lb's more than a 12a with carb ??

oops UK cars don't have A/C or powersteering or the revised dash (no RHD cars did)

Beefier rear end, bigger brakes, stock GSL-SE wheels are much heavier (larger tires), 13B and its associated hardware, etc...

2 pounds here, 10 pounds there, 1 pound here, you get the idea.

Just weigh less than the other drivers and you'll be equal!

What?!

UK cars don't have a/c?

What's up with that? I'm sure it gets hot over there too!

its the same size as the 12a tranny, just a different 5th gear ratio. i think i've read that they arent any stronger, correct me if im wrong

Manntis

AFAIK they are stronger, to handle the greater torque and HP of the 13B

gamble302

well the 12a tranny is plenty strong, ive seen one run 12's, and it ran 11's a few times too. took the abuse for quite awhile.

anyone know for sure?

i'd say your answere lies in the post above yours

MikeLMR

ummmmm not really ... max summer temps are <90degF with only maybee one or two days hitting anywhere near 90
