weight reduction 13b swap
so in order to shed another 100lbs or so i plan on converting my L67 powered XJS to 13b power from an FD RX7.
i dont really have a question. i just thought it would make for good entertainment.
side note:
the current engine has wiped out two automatics, one manual and two different flywheels in about 1,000 miles worth of driving. its not fast enough for that sort of downtime.

I love the rotary engines but I would be concerned that they do not make enough torque to push such a heavy car as the XJS. What are your thoughts?
On the other side, they just love to rev and are very smooth and as you said, much lighter. You might have to put some lighter springs in the front end.

some thing like this pix.
its all about gearing and tuning, but an unusual idea! my 3rd gen. engine made 420WHP on 104LL avgas, 500WHP on with water.meth injection. FB weighed in at 2770lbs, no driver!
you might consider it fast!
i'm still trying to find an AUDI V12 twin turbo DIESEL!
all torque engine,750lbs.ft. at 2500rpm, and it would require different gearing also, going the oppisite way!
super dependable, great MPG.

a refreshingly positive post from ronbros for once.
i like it. theyre fun cars. my roomates FD makes 720whp on 31psi with a 42R turbo, 1000cc primary and 2000cc secondary injectors with meth injection, a modest street port and 3mm apex seals. and ive personally done 180mph in the car on low boost (530whp 13psi) XD

Before you go and do something that you MIGHT regret
go rent an RX8 for a week end...
NO torque.... and to push around a 4k lbs car... you have a 3.73 rear in it already...
ok
get that RX8 and load it up with 50 lbs sacks of sand until it = the weight of you XJS
then see if you can live with that...
I would go with monster torque over any RX motor

the auto RX8 weighs about as much as my XJS does. also those cars arent turbocharged.
and lastly if you read any of my previous posts you would know that i have driven similar cars
i would go with monster torque any day of the week but since my torque monster XJS is broken 7 days a week.....
