What standard mini engine can i tune to get up to 200bhp or more
I know it will have to be made turbo to reach that but what should i go for 1275 or 1380

[R1mini]

None of them will ever produce a genuine 200hp, even if the engine can be pursuaded to produce the power, everything else like the gearbox, clutch, etc will be so stressed they won't last any time at all

Actually, there are several Mini Turbos pushing around 200. They will need driving and maintaining more sympathetically than your average boy racer might, but that would also apply to an A Series with not much over half the power.

 

1275 or 1380 doesn't alter the potential that much. A 1380 could leave the cylinders a bit thin and make it harder to get the compression ratio down, but it could also help to get the turbo to make boost sooner.

 

The real issue is if  200 horses in a Mini makes it any more enjoyable to own and drive, save for on a drag strip.

1293cc ia what I'm going for.

I may get crucified for this, but if you want to get reliable 200bhp out of a Mini, you should be looking at someting else than an A-series engine.

Especially if you want it to be affordable, too.

Specialist componants k series bmw head conversion. Supercharged with the sports head will produce 200+... very expensive but it will still be an a+ mini engine.

As above really if you want a reliable 200bhp then you need to looking at a different engine altogether. Honda and Vauxhall are the common choices.

I think that would be a wise choice. As said, it will have to have a blower of some sort on it, so that being the case, I would try to keep the bore sizes as small as possible, but work from a 1275 block of course. The Bores will then be able to stay in better shape and head gasket sealing will be more successful.

 

I haven't built that kinda HP Engine, but have read up on a few who have. They claim with select parts it can be fairly reliable, however, I will add that while that maybe the case, it would also cost serious cash.

 

Another aspect is, just because you may have 200 odd ponies on tap, you don't have to use them all the time and if used the right way, the expected life of all the drive train components could be considerably extended. Likewise, even with the right bits, used the wrong way, it could only last a few minutes.

Get yourself over to turbominis, plenty of advice, reading material and also experience in exactly this!!

I can only assume your wanting a switchable 200bhp engine? not one with 200bhp constantly on tap. Often the case you will need lesser power, but a decent boost controller to up the boost when its needed and thats the kinda plan I have with mine.

 

You will need to consider the turbo choice though, with choosing higher bhp you might sacrafice low end which can spoil the experience of driving it in anything but anger.

Why 200 BHP?  Our BMW e46 330D, with 184 BHP as standard, is more than quick enough for road use, and that weighs quite a bit more than a mini ever will.

Why not? Lol. The engine I'm building is going to be going in my weekend toy/tackday mini. It's a high spec and I've done plenty of research about turbo minis for the past 10 years!! Lol

There are always people who'll have you believe it can't be done.

Probably just because they don't have a clue how to do it, or because fred at the pub said his sisters, cousins mate at the other pub had one and it blew up after 5 minutes and killed 7 puppies.

 

Mine ran 200hp, a genuine 200hp, proven on different rolling roads. 181bhp at the wheels with 184ft/lb torque at the wheels (204ft/lb @ flywheel) running 20psi from a modern turbo with a very similar boost threshold to a std metro T3.

That engine did 40,000 miles turbocharged, major casualties were a snapped tooth off 2nd gear and the bores/rings wore out by the end so I wound the boost up to see what would kill it. It was a 1293cc, stock AE cast pistons, std crank, std rods.

 

But no, it can't be done.

 

 

 

*edit* I'm bored of typing this now, I can guarantee people are bored of hearing it too.

Nick I've followed your build on turbo minis since I started looking into Turbo minis.
In fact I think I bought your old phase 2 cam off of you! Lol

but it will be running about 300ft/lb torque and that's what makes the difference in the real world, bhp is a pointless figure.
