Miata vs Sierra/Celica
I recently found a pic of the Sierra rear end. I have an 84 Celica GTS whose rear end is almost identical. I don't think anybody in Canada makes
frames for the Sierra, only the Miata. SO, how different is the Miata from the Sierra?? Are the bolts in the same places?
I have been told to keep it Miata, but a rear end is big bucks, and I already have a Celica one. My mechanical knowledge is limited so keep it
simple!!

Well, thanks anyways. I guess nobody knows. I am trying to avoid having to weld stuff since I can't weld.

i think they are quite different, the miatia is an mazda mx5? if so they have front and back subframes the whole running gear can be one piece without
the bodywork, theres a pic on here somewhere.
i don't think the sierra is at all like this, but i don't know for sure. but if the celica is like the sierra back end there are plenty of
kits and chassis plans you could use.

You can get a Sierra frame from Haler Concepts - (the Velocity - same as Luego). A Merkur XRTi will yield most
of the Sierra bits except the engine.

This is my dilemma:
A Haler/Luego frame from England will not get on the road here in Quebec without a government-chosen engineer's report. A LOT of hassle. So it
has to be MADE here, somebody has to give it a VIN, and it has to fit a Miata or a Toyota - there are no straight axle RWD cars left where I live
unless I want an old 1975 Mustang II rustbucket from the junkyard (for $850). Don't mention S10 pickup trucks. I am aware that for about $3000 I
could buy an engine, trans, and Sierra rear end from a place in Vancouver, all imported from Olde Blighty. I would pay a few hundred more to get it
shipped the 5000 km to here.
My choices are very few, unfortunately. I stand to be corrected, but I don't think any companies make their frames in Canada, except Deman in
Ontario.
If I could, I'd order an MNR Vortex, pay the duty, taxes, $2000 cdn shipping and be done with it. But I won't be able to drive it past the
edge of my driveway.
Sorry for the impatience. It's just that I need the donor out of my buddy's driveway by the end of this week.
Seriously, a friend has a Head Gasket for a Cortina 1300 for sale. New, old stock FelPro. No: HS21105B-3. He wants 20 english pounds or $40. You can
PM me.

http://canadianlocost.com/home.htm makes frames too - probably don't provide the bolt in goodness you need. Plenty of donors out west - why not
take a cheap flight out and drive donor back?

I have an MX5 - they are double wishbone rear end on a subframe. I think that era of Celica is a semi-trailing arm so similar in concept to the
Sierra/Merkur. Semi trailing is a space-saving idea for sedans that don't have the room for better geometry - hence guys like Rorty designing a
way of taking Sierra rear components and turning them into the better double wishbone system.

Here's how it's played out so far:
Dismantled and destroyed an 84 Celica, with a 22re motor. The car cost $925.
Garage rental, labour costs: $250
Had the transmission rebuilt, as it was missing 5th gear - cost $450. Spray painted the trans yesterday, using engine enamel.
Kept the Engine, Trans, entire rear end, wheels, computer, electrics, emergency brake, and some odds and ends.
Sold the tires and rims for $50 cdn. The 4 original Toyota mags, which are in very good shape (tires aren't great) are for sale: $200 cdn
firm.
Ordered an MX5 based SR7 Module A kit from Deman Motorsports - good reputation - seem like OK blokes. Very expensive compared to your prices, but
that's the price of admission.
Bought Front brake calipers, front hubs, spindles, rear brake calipers, gauges, 13" mags, full gasket kit for the motor, TR Spitfire steering
rack, AND a cool little Lotus gear knob, off fleaBay. Cost: rather not know.
Need rear axles or diff/rear end from an MX5. Think I have sourced those. This is the only one that fits the SR7 frame, apparently. I am not an
engineer - amateur or otherwise, and not a welder, and have read enough Adams and Staniforth to keep away from that stuff!
Should this post go somewhere else? Thanks guys/girls.

Sounds like you are off to a good start. The SR7 looks like a really nice kit.
There is a guy building one up by Edmonton but I believe his has the T-bird rear end instead of Miata.

Yes, there are a couple of BEC's with the TBird diff, but I haven't seen any Miata-based ones yet. Got everything to get it rolling,
except the rear uprights and hubs - prices vary wildly. I am waiting for Dan to let me into their builder's site.
The learning curve has been steep for me, but I am realising that a kit like the Deman is actually meant to go together by design, and not my
haphazard guesses etc I am however, going to need all the help I can find so I will stay tuned.
