Hi

Im trying to find information on what can be done and cant be done with regards to engine conversions.
All i have is some information about general engine change on the transport website.
Also on a forum saying that the max cc is a extra 50% of the original engine capacity eg 2L engine into a 1L deluxe.

However if the hp is great than 15% of the original engines hp then brake upgrades are needed.
But this is just hearsay.

So just wondering is there any informaion that people have thats better than this? Or even a contact?

Cheers

this is the website

National Code Of Practice < Clickit!

a mini with a bgger engine that 1100 without disks on the front is too dangerous. if you are looking at a serious engine upgrade, you will need to spend money on brakes too.

no point going fast if you can't stop...

In SA there is no power to weight ratio rules and also on size limits.
As the engineer that came and talked at the last Hotbricks club meeting said any thing can be done just a matter of how much money you want to spend

I got cooper S brakes but am going bigger. Thinking of metro.

What engineer do you use Ben (92)?

Stuart Croser from Tonkin Consulting

thank you cheers

I would suggest you talk to Rickman Smith at transport SA. If you read the rules here ,if the car is pre 1968 then you can do what you like to it. The only thing is the car will have to be inspected for road worthyness.
As for engineers the best bloke [who has been designing and building race cars for years] is Rory Thompson. He has built many ASP clubmans for road use. He even builds 3 piece alumin rims for cars. He is assisting me with the new brakes I am building.
He is in the phone book under mechanical engineers. If you can not find a no. then PM me and I will give you his e-mail address

that would be nice but it's just not true. you must send a modifacation proposal form to transport sa and they will send you back the details on what you have to do.in most cases it will require a engineers approval that will include lane change test brake tests ect.
the gog

Craig...Give Stuart Croser an email or a phone call. He's approved more than a few Mini's now and knows the cars well (he's also as ex-hotbricks member ). He's not cheap (but I don't think any of them are as their insurance is so very expensive).

You have to get approval from a chartered professional engineer (CPEng) and I believe they must also be Transport SA approved but this may not be true. Either way give Stuart a call. He works for Tonkins Consulting at Wayville.

Without sounding blunt,

What kind of price am i looking for get a engine conversion engineered?

With any modifications if the car is pre compliance then you do not have to build the car to suit compliance regulations as the manufacturer did not carry out testing at submit this when the car was built.
With any modification you can build a pre 68 car to what ever you want !!!!!BUT!!!! the final road worthy cert is only issued IF the car is deemed safe to drive on the road.
The point of a engineer's report is to ensure that any mods and reconstruction is is done to a standard. ie welding is done correctly and componets that are modified will take any changes in stress and load. All these mods can be "calculated" for loads and stress etc.
One issue that has come to Transport SA attention recently is the issue of torque steer on some engine transplants in minis.
Look at a Formula 1 race car, there is more" engineering" done on those than any road car, but a formula 1 is not driven down a dirt road,or driven on a highway in peak hour traffic.
Over the years the number of "mods" that I have seen done to cars that are TOTALLY un-safe is unblievable. Most of these have been done by people who are do not know what the changes are doing to the rest of the componets.
Just remember one thing, if what you do "breaks" then you or someone else may end up very dead.

Stuart is the way to go... to quote him exactly...

"you can put in anything in the mini as long as it passes the brake test and the lane change test.. no issues.. you can even put 18" rims if you desire.. "

I went to him with a whole bunch of questions of what I can and cannot do.. answers to all of them were yes..

As everyone said, he is not cheap! prepare to set aside approx $3k for engineering + track testing alone!
