HIF44 Carb turbo vs non turbo
What is the difference between turbo and non-turbo HIF44 carb? There are different service kits for each.
Is the float and float needle different? How do you identify which carb you have?

Apart from the bulkhead mods its pretty straight forward, you may need to modify the wiring loom a bit depending on whether you intend to use the turbo's ecu or not. If you dont keep the ecu then it is a fairly easy conversion.

For a turbo engine you really want a s/c gearbox if your going to up the boost by any amount. cheers Paul

Thankyou for your politeness of creating a new post to talk about the responses given in an almost identical previous post. If you wish to not take heed of previous advice I believe KC has an article on this very board on this subject (might be wrong, been a little while since Ive gone through it). A helical cut gear, materials and bearings etc being equal, will be stronger than straight cut. For reasons in your previous thread another poster pointed out to you. Also for grain reasons of the steel itself. But Im no metalurgist. However, buying a new SCCR gearbox will ensure it has new, good quality bearings etc which goes a long way to making the boxes stronger. Further SC also offers less sidethrust which with gearboxes that have weaker cases can actually lead to a stronger box. A bit. From memory, the turbo fraternity found a rebuilt helical box (A+) to be the strongest solution (repeatedly discussed in this forums previous incarnation). Finally, if you want close ratio you simply have no option. You have to use a SCCR box! Of which the MiniSpares one will be better than most Im sure.

For proper advice from the guys that race with very heavily modded turbo engines i suggest going to : www.turbominis.co.uk These guys know their stuff because they have been there tried and tested and can tell you their results. unlike some of the bs that members of this forum will tell you. You know what they say, a little knowlege is more dangerous than none at all and judging by the replys to your question i feel that there is some of that going on here!

Now now Sumpnut, flattery will get you nowhere.

turbo
Hi I am currently restoring a mini pick-up and have put in a 1300 turbo which turns out to be an oversized turbo. I have adapted the engine bay and it now fits like a glove.. and just finished the re-spray..still not got it running yet though! I cannot wait to get percy running.

turbo 998
This is what I had in mind for my hilclimb attempt.... http://www.turbominis.co.uk/forums/index.php?p=vt&tid=4213 I think, probably over optimistically...that I can improve on this spec as well as I have loads of turbo exp on other cars. What are the limitations of fuel usage, can you use methanol or race fuel, you can mix up 120 octane fuel to support 25psi, this 998 was 18.3psi on pump fuel....methanol would allow considerably more boost than this but you would probably have to weld the head on to keep it from blowing head gaskets!!! I am sure you know anyway but you can build a 74mm bore 999 with a custom crank and rods for a super revvy over square 999 with lots of room for big valves. Would you get away with a 7 port head? This way you could install decent fuel injection avoiding the 5 port charge robbing nightmare... 8 valve heads are better for torque than 16v heads anyway, surely what you need in a hillclimb? I really want to do hillclimbing in a mini as well...and living in the SW there are lots of good venues.

Sounds good. One thing to bear in mind though is that turbo`d cars get very hot under the bonnet, so the more room around the turbo the better. And ideally you want some bonnet vents or something to feed some cooler air in.

can it be converted to a turbo?
hi there all mini lovers, im a girl who likes a bit of speed in my mini now and again.i have owned a vauxhall tegra 1.6 and my mini is a lot better on aceleration and handeling. but i was woundering if i could turn my 1275 mg metro engine into a turbo engine using the t3 turbo.i know that the boost would not be the same. im ready to get out the welder and grinder and give it ago. thanx guys

Unfotunately, its not quite as easy as that. The turbo puts a great strain on the engine so it has to be built, pretty much from scratch with that intent. The compression ratio for the MG Metro engine is also quite high because it was tuned as standard to give more power than a standard A series. Turbos also require quite a bit of other bits than just a turbo to get them to work right. It can be done and Im sure others out there will be able to tell you what you need, but Id like to offer the super charging option at this early stage. Its easier to install, more predictable and doesnt cause all the horrible heat management issues that a turbo does. Granted, the kit is more expensive than a turbo, but once youve bought all the other stuff needed (most of which are quite expensive) it equals itself out in the end. The main pros and cons are - Turbo - Pro - boost can be altered on the fly - Con - Tricky to set up and problems with heat and turbo reliability Supercharged - Pro - simple to fit and set up - Con - can be difficult to alter the boost becasue the drive wheel has to be changed each time.
