vr6 turbo

[twin eng, twin turbs]

hey.
those anyone have a golf mk3 turbo vr6 because i want to make one and i need people to tell me what i need to do to the internal parts of the engine.\
cheers bois

You can run up to 10 psi on standard internals as long as they are in good condition with out to many km's on them, but its having a good safe tune that is the most important thing with any custom setup...
Going the whole hog i would use Pauter rods, 8.5:1 JE pistons, ARP head/rod/main studs, inconel coated oversize supertech valves, HD valve springs, titaninum retainers, light weight lifters, Custom cam grinds to suit turbo, Alluminium flywheel and pulleys, linished crank or reground if required. Fully dynamically balanced, Custom inlet and exhaust manifolds. Port and polish and port match head and manifolds. Garrett GT35/40r with 45mm tial wastegate and a 3" exhaust. Motec or Autronic ECU. Their is so much more things than this though......

Alluminium flywheel and pulleys,

Im running the standard flywheel and pulley . Why would you play around with the harmonics and balancing of the engine without really knowing its outcome

linished crank or reground if required.

Id get the crank knife edged as well

can you imagine the time, effort and pain in the @$$ it would be to engineer a twin charged setup? wow. it makes me wanna go get drunk to not think about it at all.

quote of the week, !!!!!!!!!!!!

turbocharging is so much more efficiant than supercharging and u have almost limitless hp capabilities (for a fwd anyways)!

I've read that the stock internals can hold up to 11 intercooled pounds which I gues would be like 350hp? way too much but very cool. though 9psi is the safe option . . .

as was mentioned before, get on vwvortex and search till your heart's content!

I have balanced numerous bottom ends as an engine reconditioner and though aftermarket suppliers of alloy pulleys and flywheels say they are balanced when you balance a bottom end you balance the crank first and then add the pulley, flywheel and pressure plate and rebalance them all at once because it will be out of balance! Maybe not by much, but a decent amount will effect the bearings life, put undue stress upon the engine and reduce power and the smoothness of the engine under high revs. Knife edging is a great idea to and will reduce rotational mass as well as reducing parastatic frictional losses.

Says it all really!

I'd go a blower myself. Love that whine!

turbo ftw.....

VR6 turbo would be a better set up i recon, not a big fan on blowers

Many people have problems with the superchargers on VR6's with slack in the belt, if it is too tight, it puts too much preasure on Power steering, alternator, water pump etc, and eats them for brekkie.
If too loose then you dont make the power, most people struggle to make over 270hp with a supercharged setup.
I have read nearly all of the threads on Vortex on this.
Easy to make power with a turbo

Also Turbo FTW

Bah, what would you know...

Put a puffer on it!
