And two other reasons why I like the 4G92 over the B16A, you can independently programme the exhaust and intake cam profile change rpm on the MIVEC. That means you can have the intake cam 'changeover' at 4500rpm and the exhaust cam profile 'changeover' at 5000rpm to increase low end torque. You cant do them independently on the VTEC.




I dunno about that being that much of an advantage. Everything i've seen on variable cam controllers is that all they do is loose power. Both mitsi, and honda did countless hours of testing to get there changeover point right, so trying to gain performance by messing with it from what i've read is a fruitless excercise..

Not having a go at you at all, just adding my opinion :wink: :D
Don't worry, i have a bit of a soft spot for mitsi's too, as i just sold my Evo IX 8)

Now enough of this rubbish and back on topic :oops:

There are several versions of the B16A, you want the one with hydraulic clutch not cable.

Front cut is heaps cheaper and easier to install.

G'day Tim,

Yes you are right, but that is for the stock engine.

When you change things like exhaust manifold and pipework, inlet manifold, throttle bodies, injectors, mapping etc, being able to independently programme both exhaust and intake cam changeover points can make measurable differences over engines that cant.

Damn, should have kept the Evo!!

What was the topic again???

Cheers,
Tricky

P.S. I got a mini - Rover front cut, your joking right? :wink:

Front cut will be way easier than a full engine conversion. Potential to still be a challenge depending on your level of experience and what you are after. Would be a good introduction.

I can't really comment on the full engine conversion as I've never had one. (Have done the odd engine change in a Mini though). If you do a full conversion make sure you allow enough $$ to do it properly as most are a compromise one way or another and have the potential to dramatically change the driving dynamic that draws us to the Mini in the 1st place. Seen some awesome ones and seen some bad ones.

How much power do you really need on the road in a 650Kg car?

I agree with that. I crammed the contents from a 99 model rover into my car, and though it's relatively straight forward, it's still not a bolt in job, particularly if you retain the AC, EFI, and other stuff.

If you're just swapping the engine to a late 1275 it couldn't be easier.

Comparing a standard rover conversion with a v-tec / 4efte conversion is a waste of time.
One is a basically standard mini and one is highly modified.

You need to find out what it is you want out of the car, how much money you want to spend, how long you want it to be off the road and what work you can do yourself.

What engine does it have at the moment? Rebuilding/modifying what you have may give you better bang for your buck.
Supercharging or turbo charging an A series might be another option worth considering.
BMW twin cam head conversion might give you what you want.

Its your car, no one can tell you what will be best for you. Go for a ride in as many differently powered minis as you can, and draw up a table of pros and cons of each option before you commit.
If you want help with the pros and cons, that might be a better topic post. :wink:
