v6 tuners
- Thread starter ray
- Start date
Well if its relatively un-chartered waters we're sailing.. its not really suprising is it? Surely there's plenty of engineers out there that know how to build and offer a complete race spec and tuned V6 if you want to throw them a shed load of money..?
As you may know, i'm not a mechanicly minded person.. but just sat here reading through posts etc, it seems many people here have tried various tuning companies, and many have had the same or very similar mods with huge diffences on there end results.. from the same mod! How can this be..? Good - or bad engines..? Everything all appears rather hit and miss to me with tuning and mechanics and not as 'black and white' as I had first thought before reading so much on here..
Whats not working for you at the mo then Ray.?

Mod it to achieve what? Just more of everything, something that behaves itself as a daily driver, something that works well on a track, something that puts out 128kg Co2?
It's a pretty sweeping conclusion to come to without including what your requirements/criteria are to be honest.
You're also coming up against the problem of a niche market - this "community" is small to start with if you then look at the people who are actually interested in doing things other than adding an exhaust and induction kit it's down to single figures. The "tuners" out there have commercial interests/priority - they've little incentive to develop for the v6 when the same time/effort expended on the standard 2.0 Clio engine opens them up to a much larger customer base.
If the cheque book is sufficiently large you will be able to go out "there" and find people who, assuming a proper brief, will be able to deliver for you - but it's never going to be as simple as finding parts/expertise for mass market models.

Very valid points Max ...
For me, if I had the time and inclination, my Vee would have a 2 litre cosworth turbo engine in the back and an LSD in the gearbox. Not quite the heritage of a big engined V6 but - many challenges (as I see them) solved as far as I can see ...
1. Reduced weight and centre of gravity for improved handling.
2. Easier tuning and reduced tuning costs from a mainstream engine and tuning companies.
3. Easier maintenance.
1 & 3 would be subject to the install being well engineered.

It might only be me here thinking this but what makes our vee any different from other engines??........naff all!!! The only difference is the fact its subjected to a little more heat than other engines. Last year I managed to fit a BMW K1200RS motorbike cylinder head to a 1950's BMC designed engine block. Bare in mind that this was pretty much a bespoke motor and was running over 290bhp per liter at full boost (was a 1460cc), I could have found a fair few places to set the cam timing and fiddle with the mapping. First thing in this case was to find a similar base map using similar cams and timing, second was to up the fueling....by alot! then tweak and "tune" the motor until perfect. At 290bhp a liter and a cost well into 5 figures it had to be perfect! Due to the siamesed port lay out (two cylinders relying on one port) it was actually harder to map a standard 5 port mini as opposed to a 300+bhp one but it has been done very succesfully.
If I was to go out tomorrow, buy a spare v6 block, add H beam rods and forged pistons, ported and polished heads, a different inlet manifold etc I'm pretty damn sure i wouldn't have an issue getting it runnng right. Every weekend there's probably hundreds if not thousands of kit car owners with all different types of weired and wonderfull engines running perfectly....why do people have such an issue with ours??
Yeah thats a mini engine believe it or not and there certainly isnt a big market for ones like that...

its av 6 engine ? fun it is james ? the more you think you know the more questions arise i am no stranger to this subject but i am shocked at the lack of knowledge out there for this engine ? not car and i still think its piss poor br spec of mods and custom builds yada yada yada every ones doing there own bit great and yes you can if you have a enough money you can go to prodrive and get them to do it im just disapointed with the lack of skill out there and lack of understanding
It "shouldn't" take mega ammounts of money to sort the running or tuning of an engine and it definatly doesnt take shiny nor trick parts to either. Ive seen people spend rakes of money on motors and gearboxes only to have problems where as others would spend less but think of better solutions to avoid problems. Take that engine above for instance. Up until very recently, there was only two companies who could supply a 16v cylinder head capable of 180+bhp for a mini. To say they are expensive is an understatement. That changed when a chap in Australia was looking for a cheaper, better alternative. An example of somebody using less of his wallet and more common scence of how an engine works I reckon. Don't get me wrong, having two million sensors on an engine and an expensive super computer telling it what to do is fantastic but from personal experiance, I here of more people getting success on road cars from much cheaper alternatives. JAMSport is around the corner from me and a chap assures me he could rewire my engine bay and use a Gotech ecu to power it 100% reliably. Thing is I'm 100% sure he can as I've seen some of the one off missiles he produces and they never miss a beat. He recently knocked out a 440bhp supercharged Fiesta. Nobody had any knowledge or experiance in doing that but it still proved effective and reliable.

your like joe 90 mate fair play to you
Ok to your original thread then.
1. Buy the two heads currently on Ebay and then find one of the many decent head modifiers in the UK.
2. Have them flow tested to see what a stock head will flow.
3. Then have both heads cut up into sections across the ports to see how thick the port walls are and how much possible port work can be done. This means you and the head modifier will know what your looking at.
4. Cam wise there are loads of different profiles out there from other different engines. Question is, what one do you want for your type of driving. Kent, Piper and Cat Cams can all supply billet or reprofiled cams for your needs and they are the best people to talk to.
5. Bottom end wise your half way there with that crank you have :wink: but rods and pistons aren't hard to get just a little pricey if they are one offs.

And a set of Accralite forged pistons- Which I just happen to have a set of and would be willing to sell if the offer was right.

Hi,
Managed to get a Pair of tyres from France so am now looking to sell the forged pistons that i have.
These pistons are new and cost a lot, I am open to sensible offers.
