Car Forum / MINI / July 2005Choose an engine
Hi all I am busy rebuilding my mini. I am in the process of moving the radiator to the boot and adding widened rear panels to accomodate air ducts into the boot. the reason for this is that here in South Africa the Minis are prone to overheating and I am hoping by doing this and adding two electric fans on a larger radiator might solve the problem. Any opinions? Secondly, I also want to know your thoughts on engine choice. I have a 1275 lump with 40 o-size pistons. I was thinking of using this engine with a turbocharger. My next option would be to use a 1800 16v Volkswagen Golf engine & box(which I can get at the same price as the turbo alone) and fitting this in the car. I know space is limited but it's doable. I've seen a few similar conversions in the past. This car is to be used strictly for fun, so practicality is not an issue. Any thoughts welcome. Thanks Maverick I am running an MG Metro in my Moke here in SoCal. Last week temps were in 110 degree range and no overheating. Basically saying if engine is running with proper timing and correct radiator with water wetter then no drastic change needs to be made. http://austinmini.ositech.net > Hi all > [quoted text clipped - 19 lines] > Thanks > Maverick > I am running an MG Metro in my Moke here in SoCal.

Whats water wetter? rm > http://austinmini.ositech.net > [quoted text clipped - 21 lines] >>Thanks >>Maverick It is a bottled substance that claims to make your coolant work better. I have never needed to use it but others say that it is good in a hot engine. The Muffin Man >> I am running an MG Metro in my Moke here in SoCal.

I am not familiar with water wetter, but i am using "anti-freeze". I don't know how high temps get here, but between my mini, my dad's and my sister's I can asure you that it is definitely a problem here. P.S: just before everybody starts asking questions: Thermostat and waterpump fine, engine flushed. Cyclinder head is not cracked. Everything's in working order,basically. The mini spares 2 core "super" rad cools very well, probably the best, with a oil cooler you should be ok, Steve. > Well, I'm sure my timing is correct, and I have a brand new 4core > radiator in it.

Hi, A thermostatically controlled fan fitted to your existing radiator should give you all the coolong you need.

A 2 core ST "super rad" from mini spares is cheaper than a kenlow fan & thermostat kit! you could fit both though, Steve. > Hi, > A thermostatically controlled fan fitted to your existing radiator should [quoted text clipped - 17 lines] >> > waterpump fine, engine flushed.

I wouldn't bother with the Turbo personally if you are having overheating problems with a standard engine as they do create a lot of underbonnet heat and you still wouldn't be able to get a reliable power output anywhere near the VW engine without throwing money at it, not forgetting that BL decided the turbo 'box could only just take 110lb/ft torque reliably and so limited the boost at the lower rev ranges to reduce warranty problems, I am not saying that you can't make them a bit more reliable but you do need to spend lot of money on them to get them anywhere near proper German engineering:-) before anyone calls me unimaginable things, yes I do own a mini and a mk1 Golf gti and I like driving them both, although the mini is quicker! miniman
