Hi All,

For as long as I can remember I have wanted a VTEC in a mini, I have had many minis over the years, I dabbled with a sirion converted Moke which was fun, but life saw me having to sell it. I shouldnt have wasted my time as my hunger was never quenched.
I am now in a position to start a build, and so it begins..

The Mini -
68 Austin Mini
850 Manual
Stock standard car with a terrible brushed on paint job

Image

The Honda:
B16A2 Honda Engine
Custom headers
mFactory Helical LSD
mFactory 4.00 final drive
LS 5th Gear conversion
Modified spliced Honda/Mini loom
Hasport poly mounts
Allspeed driveshafts and HD CVs

Image


My plan is to build my own frame to fit the Honda engine into my round nose without extending or modifying the front.

I have discussed my plan with an engineer who has given me all the relevant info to get it passed and registered.

Here are some pics of the shopping so far

Later model interior from a rover

Hasport poly mounts

mFactory final drive and LSD

Image

I have been collecting parts for a few months and trying to get my head around the wiring diagram and how to reduce as much wiring as possible, I plan to keep the mini loom for everything besides the engine, and have the Honda loom for the dash and engine.

I am also planning to try and put AC into the mini pillaging parts from multiple systems, hopefully finding parts that will fit in the limited room I have but I’m aware that this may not eventuate due to space requirements,

I have made some small progress on it,

I have hot washed the engine ready for painting

Image

Image

I have also chopped up the rover front subframe I have ready for starting the subframe build,

Image

The gearbox was dropped off with the final drive, lsd and 5th gear to be cleaned and assembled by NEAT gearboxes here in Adelaide earlier this week

When work and life permits I will start to strip the mini engine out and start the subframe,

It will be a slow project but i will keep you all updated as things happen.

Cheers,
Nick

Great project, and looks like you've done your research with the parts that you're selected.
It's quite ambitious keeping air conditioning. Does your "68 Austin" have factory air?

I’ve tried to do as much homework as I could.. dutchys Honda conversion has been a huge inspiration and help, and he has graciously supplied me a lot of information and put up with me asking a lot of questions

My mini was pre air conditioning as I believe this was only on Japanese rover minis starting from around 1987

Sorry for the question, only asking because that clearly is/was a Japanese rover mini.
. one piece Windows
. rear seatbelt mounting points
. interior trim, fixtures
. concealed hinges
. fender mounted mirror holes

Wrong, it is actually an English imported mini.. probably MkIV where’s rovers were MkV - VII

Ah, gotcha. You're probably better off with using a small Honda or Jap a/c system anyway as they use the modern refrigerants and poly V belts like your b16 crank pulley.

Good to see another Honda Mini in the works in this country - they're a bit of rarity.

If I can offer you two tips for the build based on if I was to do another one:

1. Buy an allspeed subframe - mainly for the time saving convenience more than anything else. The subframe is only a small part of the build. It's not difficult to build a frame that holds an engine, it's the countless times you have to go back and adjust it if you put something in a place thats not suitable.

2. Don't get too caught up on the air con. It's also not an engineering requirement, so can be added afterwards. Though I have AC in mine, it will be removed for engineering and the first few months of road use till I'm sure that nothing mechanical needs to be revisited, all to save a de-gas and re-gas each time.

Thanks for the tips Harley,

I am aiming to build a frame as close to dutchys as possible as I know this is working shape and design
And it’s what I showed my engineer as an example when chatting to him

As for the AC, if I can make it fit I’ll be happy but your right it’s very much a secondary feature, and not make or break. I have found a nice size compressor which I’m keen to try from a Daihatsu sirion but I need to wait and see where I can fit it, and more importantly where I can fit the condensor

Nice compact unit. Are you reverse mounting the compressor? The Sirion motors run opposite direction to Hondas don't they?

I’m not sure if they run in reverse?

I was under the impression that they ran the same so I was planning not to reverse the compressor but it might make it easier if I can.

Did a little more yesterday, started removing the engine and wiring.. hit a snag though as I couldn’t undo the bottom subframe bolts on my own (needed someone on the other side)

Also cleaned up my sportspack steering rack that I got from England, this has the limiters built in for larger wheels so they don’t scrub,
