|The V8 Miata project|
|July 18, 2008 - When last you heard from Elvis(our 2002), he had competed in the Car and Driver Supertuner Challenge back in '03.
Since new the car has had at least five engines.|
It's been used as a development platform for everything from big turbos to high-compression naturally aspirated strokers.
Now it's time for sacrilege.
We're going to install a Chevy LS1, using the V8 Roadsters kit we recently added to our catalog. We will be keeping close watch on weights and weight distribution to make sure we don't turn a sweet handling car into a pig. This will not be the white jumpsuit era Elvis!
|July 18, 2008 - Here is the complete V8 Roadsters subframe kit and diff mounting kit.|
It is very complete and includes new engine, trans and diff mounts, mounting hardware, etc. It uses frame rails similar to the FM rails to strengthen the chassis and tie the rear trans mount in. No matter what year car, all of the subframes are built with the improved NB control arm mounting points.
Our V8 conversion parts
|July 18, 2008 - Bill came in at the end of his day off to do a little maniacal destruction,er "fabrication" on the oil pan.|
A section has to be removed to clear the steering rack.
|July 18, 2008 - Elvis' 11/1 CR two litre oozes precious fluids after Keith and Brandon de-four cylinder the car.|
When using a lift, we find it easiest to drop the entire drivetrain and suspension at once.
|July 18, 2008 - Heck of a time to find "somebody" re-assembled the engine stand backwards.
At times like this the forklift is really handy.|
|July 18, 2008 - The oil pan needs some modification to clear the steering rack.|
|July 18, 2008 - Pan back together and hole for oil level switch filled.|
Still needs to be water tested for leaks.
|July 18, 2008 - Block hugger headers.|
Yes, we're going to want to insulate that starter.
|July 18, 2008 - Elvis before being gutted.|
1/2 tank of gas, FM 2 litre stroker with RB header. Let's see how close we can get with an extra four cylinders!
|July 18, 2008 - Brandon swapped the control arms, rack and shocks over to the new subframe.|
We *should* be able to just lower the car back over the whole thing when the engine and trans are back on.
|July 18, 2008 - It's the latest craze, kidz!|
Keith caught sniffing brake fluid.
|July 18, 2008 - The differential is a brand new Cadillac CTS part.|
It's a 3.42 ratio and would be a really nice upgrade for any high-power Miata - no matter how many cylinders it has! Yes, we're planning to make it available.
|July 18, 2008 - The differential is mounted using this bolt-on bracket.|
A couple of tabs are welded on to the rear subframe to locate the nose of the diff. It's very slick and fits beautifully.
|July 22, 2008 - The Miata's clutch master cylinder is 5/8".|
For the T56 clutch, we need a larger bore than that. This clutch kit fits a 7/8" master with a remote bleed screw to the Miata.
|July 24, 2008 - Water testing the pan.
After cutting and welding the pan, we tested for leaks by filling with water.|
After fixing two pinholes, it has held for a couple of days.
|July 24, 2008 - No, something terrible hasn't happened to Elvis!|
There is a fair amount of trimming involved where the frame rails meet the firewall to make room for the larger (MUCH LARGER!) new engine. We figured we would practice on a crash test dummy.
|July 24, 2008 - Drop the torch and step away from the vehicle!|
On the dummy car we did initial cutting with a torch for expediency. We will probably use plasma cutter and grinders to make the real cuts cleaner.
|July 24, 2008 - Dash-ectomy?|
The trans tunnel needs to be widened right at the firewall to clear the new bellhousing. It's easiest and safest to do this with the dash out and carpet pulled back.
|July 25, 2008 - More dashboard mayhem!|
|July 28, 2008 - Sad little guinea pig.
We figured we would practice our frame rail cuts on a terminal patient.|
Plasma cutters are wonderful things!
