Thought it was about time I got these pics up
The conversion started Xmas 2004 & after quiet a few delays, like a rebuild on my
Cooper S after it broke a valve spring, lack of finances, just getting p*******d off with
spending heeps of time on it & seeing no real progress the car is now finally finished
& on the road YAHOO!

The car was purchased in Toowoomba early 2004 & although was generally in quite
good nick was fitted with an Aplus 1275 that was a little disapointing as far as power
was concerned but smooth. I decided to go down the Suzuki G13B conversion route
rather than rebuild the A series & (hot) it up

First the engine bay was stripped out & front subframe removed, the wireing harness
was a disarster so that ended up getting the big chop & thrown into the corner
I knew basically how I was going to build the new subframe (thanks to DT) but how to
bend the tubes presented a bit of a problem. I sent some samples to a friend in Sydney
he computor bent a few sets for me Problem Solved & he still has the program.
Next build a jig to hold the subframe to stop things twisting when the welding started

Here's the jig note the big yellow brace bolted to the top of the towers, this stops the towers from twisting & pulling in


Image


This photo shows the almost completed subframe in the jig, the yellow brackets where
the bottom suspension arms go were use to locate the engine. I had a dummy gearbox &
just put a long shaft through the diff to support the engine on these brackets


Image

Here's the completed subframe



Image
Image
Image
Image

Engine mounts

Image
Image
Image

The bottom suspension arm mount is boxed in

Image

Mini pot joint driveshafts are used. This is the sliding jig I used to get the correct length
for each shaft. The shaft was cut & resplined to suit the Suzuki pot joint

Image
Image

A hole is cut in the r/h inner guard to alloy the mounting of the alternator

Image

Alternator mount was then fabricated

Image
Image

Fabricated adjustable tie bars & Mini Spares adjustable bottom suspension arms

Image
Image
Image

Suzuki gearshift mount & cut/shut shift rods

Image
Image

Engine bay all nicely repainted with subframe installed

Image
Image
Image


VL Commodor fuel pump & filters

Image

Metro turbo ventilated brakes useing a single hose. The machined up block joins the
ports in the 4 spot calliper

Image
Image
Image

Final engine installed with SR20 throttle body & front mount AFM & K&N filter

Image

A Diahatsu 1200 radiator fits perfectly with just a little taken out of the fan shroud
A combination of V8 Valiant & Datsun 1200 make up the radiator hoses

Image

So here it is all finished, looking fairly standard (which is what I wanted) complete with
"granny" rear louver, Honda Prelude front bucket seats & 12x5 Superlites
Next job fit the Mini Spares dash & redo the interior
Who can pick the decals?
ENJOY

The guy who bent the tubes up manufactures motorcycle stands & the machine that bends them uses a computor generated drawing/program to make the compound bends at the correct distance & angle. Although the bends are'nt "mandrel bent" you would think they were they are that good

Great job Blue!

Another succesful Suzuki conversion......

Enjoy the fruits of your labour - and good to see you sharing your wealth on knowledge wit the rest of us.

Q: Is there sufficient clearance between the alternator and the wheel on full lock and full compression (bump)??

Nice use of alternative parts too (Datsun 1200 rad etc)

Cheers,
Tricky

very interesting.... I'll keep that in mind - will he do it for others?

I'm sure you have this under control, but it made me have a double-take. the adjustable tie bars you've made using a steering tie-rod end - tie rod ends aren't made for those kind of forces, and do wear out. Just keep an eye on them for wear, as using them for caster control does put a lot of force on them....

The forces on the tie rod ends are in the same plane, weather they be used on the
steering rack or on the tie bars
DT has been useing the same sutup for about 6 years still with the original tie rod ends
& they are as good as new
