Nope V6 turbo kits come in either single or twin configurations.. i'll have to look up the name for the manifold / turbo configuration when I get home as I dont have it on me now...
You can use one slightly larger turbo instead of two smaller blowers, only thing is when you have 2 aftermarket blowers you got to balance them ( maintain equal boost from both ) and that the fun part lol

this was posted on the coupe forum, its a transcript from the owener after one member emailed him, i can see anyone proble with posting it here as permission was given on that forum:
I have had The Stealth Systems Coupe for 5 years now . I am going to put it up for sale in mid Aug latest as am away most of July due to getting married.
We have set the Supercharger to run at 12psi which would be putting out around 350bhp and the current multipoint nitrous is set at 150bhp. This is after lots of trial and error with breaking belts (well destroying them) and getting traction. It now runs very well, good traction and does not wreck the toothed belt option we are running.
The cost of doing these conversions is very expensive and would be cheaper for me to use the gear from the coupe + scrap the body. I can'y bring myself to do it and want it to go to a good home. I could have sold it to a German Coupe owner last week, but he wanted to strip it out to use as a track car and said he only needed it to last a season.
I have spent probably 25K plus on this car (probably more) and some of the work that was free would have cost an arm & a leg. Things like one off alloy fuel rails, one off multipoint set up, one off shocks etc.
The beige leather, dials, respray, bodykit, wheels, complete engine build, fuelling, stand alone 2k ECU, wiring, stereo, carbon bonnet (2.5K) and so on made the car to hard to break up for bits. Even the exhaust is twin exit 3 inch with cat by pass or full race cat and vortex mid section (£3K).
If you know anyone who is a Coupe enthusiast and wants it I would be looking at around 11.5K, which is well cheap. Would even take a PX as will need a car till I get something sorted out.
I will put it through an MOT & full service at start of Aug and I have a folder full of info from a ground up rebuild all in pics. Loads of mods since the Sept 03 Max Power feature.
Car has done 24K since original conversion, 63K in total and about 5k since the new ecu, fuelling and charger set up.
This car has had a really easy life as at the age of 38 I have had enough turbo cars etc to appreciate longevity. I change the oil at least twice a year and last 3 years I have only done 2-3K a year. I never put my foot down with the oil/water cold and the car has loads of safety features. Dual core alloy intercooler and methanol/water injection keep the charge temp down. The supercharger has an extra high pressure oil feed like a drag car and the ECU is probably the best on the market and can be re tuned to suit any future mods. This is done on the go and not on a rolling road. Rolling roads cannot simulate normal air flow and therefore cannot get the tuning spot on.
so the reason its only 350 without the spray is due to the way the charger is driven

yeah but you have huge flow problems with a 6 cylinder into 1 turbo you have to be incredibly trick with manifold design to make it work well generally your better off going twin turboNiz406 wrote:Nope V6 turbo kits come in either single or twin configurations.. i'll have to look up the name for the manifold / turbo configuration when I get home as I dont have it on me now...

thats a hell of an underestimate i have seen an mi16 turbo pushing 700bhpNiz406 wrote:indeed !
Would love to twin tub a V6 210hp ! have a nice 350hp motor !

ok thats modded to hell but i would expect about 450+ with a tt 3litre v6.
also i would choose the non VVTI 200bhp model the cam shifts to a pretty wild cam with the vvti the overlap of such a cam would spit the boost straight back out the exhaust, this is one of the many reasons why vtec's are a pig to turbo charge yes its doable but not easily

wat the hell ??????????????? only 300bhp that charger must be running like 4 psi or something :/ pointless tbh, im also not a fan of nitrous on road cars, i like power when i need it not just when i have gas in the tank. and gas becomes expensive if you use it :/Niz406 wrote:Dude seen that before... theres only one problem with it !
Its only 300hp without the spray.... the tight sod would rather have 500hp from a gas tap and not from the pedal !

this is bs 12psi on the v6 engine WILLl be more than 350bhp i would do the maths but its late and i cant be assed ill take a look through my books laterRick_J wrote:this was posted on the coupe forum, its a transcript from the owener after one member emailed him, i can see anyone proble with posting it here as permission was given on that forum:
