Well you either want good reliable power and good low down torque with no stupid turbo lag, or you want to have a car that goes tah tah tah when you back off so everybody looks...

A small blower kit would set you back a few grand, but its bolt on and lets go, no issues with warranty. No jerking around with oil and water lines to the turbo, making new exhaust manifolds etc. No tuning problems. No heat problems.

I don't really care what you do, but i thought i'd steer you in the right direction before you go wasting your money on a second hand turbo that is most likely knackered and all the other crap, only to give up before its finished because it was never going to be any good.

Where would you get something like that from for a few grand ?

I know a Vortec will cost you around 5K

Having made custom turbo set ups on my mk2 8v, a twin turbo set up on my twin eng mk1 and a larger custom set up on my audi a4 i can give you some valuable advice. Steer clear of the older bushed bearing turbos like the t25, t28 and even the t3 off of the vl bommodores, they are to small and restrictive on a vr6. Preen may hate turbos with a vengence but he has been in my mk2 and knows it suffers from next to no lag due to the modified high flow roller bearing ihi vf22 turbo. It comes on boost at 1500rpm and flows 450hp! I run roller bearing GT garretts on the other cars. To get the best drivability and power even if you dont want to run huge boost a roller bearing garrett GT series is the way to go on the vr6. A GT30r with a .64 air ratio exhaust will boost up super fast with stock compression and from what you have stated you are after it would be a good choice. Dont go to big turbo wise though because then you will get lag. Even a later model r33 skyline turbo off the rb25 is ball bearing and is a cheap option though you are limited to 14psi because of the ceramic exhaust wheel flying apart. Steer clear of the rb20 turbo though they look very similar the rb20 it is bush bearing. For the best response make your exhaust manifold as short as possible, this will give the not just the gas flow but the flame front from the engines exhaust stroke hitting the turbine wheel and spooling it faster! Tuned length manifolds will make more power up in the top of the rev range but if you are after drivabilty a short runner design is best.

I do have some experience yes! Have worked on many a Skyline and other turbo imports.

As "twin eng, twin turbs" said, an RB25 turbo would be good and easy to find, plus cheap, or even a VG30 BB turbo would be alright, as long as its not one of the single smaller TT ones from the 300zx, you want one off a VQ30DET (ie Nissan Cima) motor. A GT35/40 off an XR6 would be nice, but probably a tad big for what you want.

Making the manifold will be the hardest and most expensive part of the process unless you can do it yourself or know someone who can do it for you cheap!
