big power vr6's?

[stevegolfvr6 0]

im currently looking a turbo charging my vr6, im wantin to go for big power and was wondering about a few things 1st.

what is the current biggest power vr6 in the uk?

whats the fastest vr6 (1/4 mile, 0-60 and top speed ect) in the uk?

what sort of gearbox will be needed to cope with big power (std 2.8 or 2.9 cope, with lsd obviously) ?

can the 2.8 be bored out to a 3.0 ?

when a 3.0 can a strong engine be had from it, as in are the bores very thin and wont cope with huge power ?

any help will be great, cheers

You're right mate, boring out to 3.0 would make it weaker. Better of keeping the 2.8 as it is or going to a 2.9 but to be honest I wouldn't bother...the difference would be minimal. A turbo conversion will cost approx £5k in total. Pretty expensive but the best way to get big power..around 400bhp+. The standard gearbox should cope ok but lsd or an uprated diff would be a good idea to put down the extra power. There aren't many turbo conversions on the VR6 in the UK. If you speak to The Phirm they have just done one taking their golf up to over 400bhp. I've seen it in person and it is one nice car. Its just been featured in Performance VW magazine. The Phirm are one of the best around at tuning VR6's. I would say their's is one of the most powerful mark 3 in the UK. I'd estimate quarter mile would be low 12 secs and 0-60 low 4 secs. If you visit The Phirm they may take you out in it.

ok mate, im planning to run alot more power than 400bhp tbh, ive seen they can get double that from across the pond in the states so i think 600-700bhp is roughly what im planning on goin for (final figure).

ive got the pvw mag and seen the phirms turbo vr6 and for what it has had done its produing good power, mite have a chat with them and run threw a few ideas.

thought the lsd would be a big gain as with any powerful fwd tractions a problem, is there any diffrence between the golf or corrado gearbox ?

low 12's aint bad but im currently doin that with my other car so wanna b takin a sec of that if possible

thanks very much for ur help, any1 else hav any facts/info please pass it this way

Hope you have a spare 10k lying about because thats approx how much it will cost to get that type of power maybe more personally i think 400bhp would be suficient unless your only going to drive it up and down the strip it will be horrible to drive unless you get a 4- wheel drive conversion and stealth quoted me 12k so no no for me but if you got the cash to fling about go for it and cant wait to see the dyno figures and maybe a vid if you go ahead.

ive got a fair bit of cash to spend, was lookin to go jap but tbh there to common and every1 expects then to be quick, but goin to be doin it in a 2 stages, 1st will be the top half of the engine with turbo and nos, then it will be to build a bullet proof (as poss) bottom end and drop it in the hole, thinkin prob bout 400-450bhp with stage 1 and 600-700bhp with stage 2

[tubby 0]

what turbo kit you going with for that sort of power at stage one ?

[stevegolfvr6 0]

not sure if im gonna buy off the shelf or go custom tbh, depends whats avalible off the shelf tbh lol

You should check out eip tuning in the usa if you are serious about that type of power and the phirm can supply all the kit you need to go all the way up to 680 wheel horse power.

hope you find it useful.

Unless you're going 4WD then 400-450hp is going to basically eliminate your first couple of gears even with an LSD. Hell of a lot of cash though.

Bear in mind that weight reduction will get you fast times on a track. It's make more difference removing stuff like soundproofing than trying to stretch extra HP out of your engine.

P.S. If you want to go big and need a new base let me know because I can get you an R32 engine or a V6 4Motion.

Incorrect.

Sorry.

Realistic power levels and a good plan. Stock bottom end is good for 450 odd with a head spacer, but dont run much more before you strengthen up the bottom. For over 600 you will need rods as well as pistons, go with ARP head studs, main studs and rod bolts and a nice low compression

There a bit of info here http://www.vr6oc.com/e107_plugins/forum/forum_viewtopic.php?128066.0 and theres a good few more posts with good info in them on this site.

If you need any more info feel free to mail me.

Should have made myself clear there. By eliminate I meant in a wheel spinning high revs sort of way. In other words: wouldn't it be difficult to get the power down without wheelspin?

You can fit a raceloogic launch/traction control system or similar - u wont get any wheel spin then :0)

[IbiVR 0]

No not really - I see what you mean though. Its all about adjusting your driving to the car - if you drive it like a saxo then yeah you'll spin the wheels up and end up in a hedge soon enough, but its actually surprisingly easy to get it all down as you learn the car and be more progresive with the gas

As you start to get in to even higher power figures, if you start to struggel you can control boost with something like the Apex-i AVC-R, you can set boost levels for different gears, different rpms etc to allow you to get off the line nicely, and stop you blowing gearbox's apart on gear changes etc.

Another option is to lengthen your gearing a touch - theres loads of options, where theres a will theres a way.

Sorry should've explained myself more in the first place - its not been a great day, lol.

Ha I've got it on my car but its never been setup - keep forgetting to get it done, should get some good 1/4 mile times with it running

mmm, looks fairly comprehensive, however its alot of money for what you get - and the biggie - it wont fit a right hand drive car. HGP do some good stuff though.

Tom.

[Bazmcc 0]

That's a hell of a lot of stuff in there. probably not a bad price by the time you count it up seperately. Plus points would be getting everything in one go, getting a Garret turbo, Samco Pipes, intercooler piping, short runner intake mani. Down points would be not knowing the quality of the other unnamed parts (I can't read german). Why doesn't it fit a RHD?

if ya dont mind me askin why wont it fit on our right hand drive cars? obviously they have a slight diffrent lay out in the engine bay but thought it was just the downpipe that caused the problems?

ive got that problem at the mo with my other car, if i want it to the car wont grab traction till 4th with ease, but put the power down propally i can grab it but the begining/half way thro 3rd, so believe im used to big power fwds and know it aint bout just plantin ya right foot the problems could be sorted with a custom lsd box with longer ratios which im sure can be found for the vr6 aswel, yeah ?

[stevegolfvr6 0]

looks fast forwarded in sum spots but not sure lol

The VR has more weight over the wheels, and a longer box in the first place - you wont have the same probs with it. Although if your going over 400bhp then an LSD will sort it right out.

You can easily get longer ratio's into the box too.

Put up a post about your R5 if you have pics etc - sounds interesting, be nice to see it.
