Subject: Renesis & REW rear housing differences was Re:
[FlyRotary] Re: Nice Trip
Hi Guys,
Attached are pix of a Renesis Auto rear housing
along side an REW Manual rear housing. The Renesis Manual rear housing is
the same as the REW manual. Following email will
have a couple of more pix.
The Renesis Auto rear housing appears to be the
same in every respect bolt pattern wise to a Cosmo Auto rear housing
(except that the oil drain goes to the left ( plug side), and the
bulge on the right for the side exhaust port.
Further, I have recently had several
different engines in two different cars, one an auto Series III, and
the other one a manual Series II, so the housings will fit on the same bell
housing pattern irrespective of it being auto or manual. I can
therefore categorically state that from around about Q3 1973, the bolt
pattern on the rear of ALL Madza housings is identical with respect to the
dowels and most of the bolts..
There are SOME differences between the Renesis
Auto & Manual in that because the auto starter is mounted on the side,
a la Cosmo, then the bolt hole that is in line with the plugs is not
there. To replace this, Madza but an extra bolt lug at the very top
in place of the cut-out that appears on the manual motors. There are a few
different auto flex plates, which have to be matched with the correct
stater snount length etc. Gets complicated when the autos went from 3
speed to 4 speed. Ther are also differences betwen the 12A and 13B auto
starters and flex plates. TOO complicated to get involved in
here.
The essential issue is that ANY Madza housing
post Q3 19'73 (change over from twin dizzy to single dizzy config),
will fit on ANY post Q3 1973 bell housing. Some mods might have to be made
for particular models.
For example, the EARLY single dizzy auto
engines in the late '73 RX2s, peculiarly, had a TOP starter,
but were fairly rare. The '74 onwards all had bottom starters. But
in ALL instances, the two dowel bolts and dowels, plus the right
bottom and top left bolts are in EXACTLY the same place. (See Jpeg) on following
email.
The post '86 RX7 rear housings lacked the
second bolt on the cut-out on the top (see pic of RX7 Series VI turbo engine in
crate). Minor differences, but I can categorically state that any
post '74 engine will bolt up to ANY post '74 bell housing. Starter
motor snout length CAN be a problem. There are a couple of "orphan" (Japan
only) bell housings floating about for which flex plates and starter
lengths are an issue.
Pic this post show the Renesis WL bolted up to a
Series II (1982) RX7 manual bell housing. Note extra lug at
top.
Other pic shows top view of REW Series VI RX7
engine in crate. Note top cutout.
Third pic shows backside of RX8 Auto rear
housing. Note oil drain gallery to left. REW and earlier drain to the
right.
Enjoy,
Leon

Tracy or anyone,
I'm just getting blasted by some Yank that is not
happy with the engines he got from Rupert here locally. I went and inspected
the engines for this chap to see that they looked OK and nothing was
missing, as a favour.
Now he's not happy that their not auto's and he
doesn't know how to change them over. He also complained that the Renesis
engine had 13B housings and he was getting ripped-off, I tried to explain that
the Renesis was a 13B.
BTW this chap is a Mechanical Engineer and worked
for many Aviation related companies. He is also doing his own PSRU and is now
complaining there is a difference between the
Renesis manual and the Auto gearbox bolt pattern and the manual pattern makes
this harder for him.
The only thing I can think of is that one of them
has the Cosmo ( extra top mount position) bolt pattern or that the
starter mounting holes are different.
The engines are on the other side of town, so I
can't see them directly.
Any suggestions on what ( if anything) is
different, I would like to respond to this chap as he's a real
pain.
Paul a photo of the Renesis from the flywheel
side would help, if you would be so kind.

Tracy,
Glad to hear you got a small break from slaveing to
produce all those products
for us !! Charlie ,Ken,Monty and I will be headed your way in a
few days......How

Got back today from Charlie & Tupper's Fly-in at Outer
Slobovia. Always a treat. Had big head-winds on way up but got
paid back with an equally strong tailwind on the way back. The
psychological effect of seeing 200+ cruise speeds is a kick! First
time using the oxygen system and it really makes high altitude cruising a
lot nicer. Stayed at 16,500 most of the time and felt great on
arrival rather than the need for a nap like I usually feel.
The Renesis continues to get better all the time as it breaks in and
I get the engine controller fine tuned to it. Only glitch was the
sluggish engine start after the engine cold soaked over night. Need
to switch from 15W - 50 to 10W - 30 for the winter. Or maybe its
that weenie motorcycle battery I use? Anyway, another pleasurable 6
rotary powered hours added to the Hobbs.
