Hakan's VR6 TURBO Build (slow progress)

[Hakan]

I've been planning and dreaming about building a turbo vr6 motor for a few years now. Im getting over the 128kw with not enough pull so I decided to buy another VR6 engine instead and rebuild it as I have money to spend on it therefore it will be a pretty slow build after stripping it down.
I saw one at the wreckers 1.5 years ago but I was to busy building my current vr6, So I went back 3 weeks ago and saw the same car and guess what? the engine was still in there I got quoted $330 so I put a deposit on it but they did tell me that It had a KNOCK on it and they cranked it over a few times and it wouldnt turn after a few degrees :0 the odometer said 83,xxxKms out of a Auto'1996 golf mk3 and externally the engine is super clean .

Today 29/09/2012 1:30PM I was in a good mood so I decided to pick up the engine and bring it where it belongs

Finally Look whose Home ready to be stripped naked I had enough of typing pictures will tell you the rest of the Story

[Hakan]

My aim is to get over 300/FWKW with the help of
Wossner forged 81.5mm piston and forged rods
Larger cams
Larger valves
HD valve train
port and polished head
twin scroll custom Turbo manifold
Turbo= havnt really decided if i want to go single or twin turbo but I was thinking of twin GT3076R or Single GT3582R ?
Injectors
big fuel pump
fpr
and more

[Hakan]

So let the stripping BEGIN....
Manifolds come OFF ..

Cam cover and timing chains come off (there were no guides just a few pieces hanging

Head comes off and we had bent valves awells were changing them anyway .SO THATS WHAT THE KNOCK WAS luckily there was no hole on the pistons. thats the first time i've ever seen bent valves in my life. so happy to be rebuilding a vr6 again but this time for power.But ive got another project drift car to finish off and then ill be starting to buy parts for the VR6. Im only on apprentice wages so money is hard to earn If your asking how long this engine will take to finish im guess until i get my full licence which is around 2 years so it will be a pretty slow build by saying that i still have to strengthen my 02A gearbox with stronger gears 3.94 r&p and LSD, driveshafts ,clutch,flywheel also a STANDALONE ECU .all of it will be in this thread . Feel free to comment and ask questions. Im still researching for parts and ways to build a power Vr6 . This car will be used for Street/track 1/4 mile purposes to teach those v8 boys a lesson

Nice. Good luck too you sir. Pm me if you need. An extra hand, obviously never done it but enough research to do so.

Single gt35 will be best. With a .82ar seems to be the consensus.

Nice!
I vote twin turbo. Purely because i've never read/seen of anyone doing that on a VR6 before.
Good job though dude I'm tuning in to this!

[KI11Z]

nice work! and a bloody steal for $300! damn son...... 2years is a long time, I hope the build eventuates and you don't lose motivation in that time ...lol, look forward to tracking the progress

[Pmk]

Dayam $300 is nothing ! This looks awesome so far man. I wanted to do the same but.. Not worth converting mine !haha Gl with it !

Skip the old GT garrett cast comp wheel turbos. Run a GTX series billet comp wheel as a minimum.

For about the same price, I would go with precision turbo's new CEA 6262 billet comp wheel, or Comp turbo's Triplex BB 6262 billet turbo. They're pretty much the equivalent to Garrett's GT35 (61mm GT35 comp wheel vs 62mm PTE's 6262 comp wheel).

Edit: I'd run single turbo purely for economic reasons, not mentioning weight, packaging problems

Thanks mate will do but right now I am gathering as much information as possible such as :
what size injectors ?
how much to oversize exhaust valves?
difference between 3 angle and 5 angle valve jobs and the benefits ?
What size cams for turbo ?
porting and polishing head ?
fuel pump?
Lugtronic stanalone but who would be able to tune it ?
to oversize pistons or not also if i just get it honed would i still need to get larger rings than std?
what main bearings to use ?
what conrods to use i.e H beam or I beam
i need lots of measuring tools !
as for Turbo i decided to go with a single Precision Cea 6262 twinscroll

[YoungDubber]

Sounds dope! Good luck with the build and hope theres not too many bumps along the way!

UUUGGHH your making me want to keep my VR6

I'd personally go 2mm oversize intake and exhaust valves, a port and polish, cams from whatever company sells turbo specific cams for a vr6. as far as i know all the bearings a stuff are of roughly the same quality (correct me if im wrong!). Dont know anything about standalone sorry!
i did a fair bit of work to my vr6 a couple years ago and got all my parts from www.fourseasonstuning.com just select your car and engine like you would on any of those sort of sites and youll see they have HEAPS of stuff for a vr6. the guy who i dealt with has or atleast at the time had a supercharged vr6 and was really very helpful, cant remember his name!
I went for the oversize pistons, only the cast ones from a european version 2.9l vr6, so only 1mm bigger. i went those ones becausei couldnt justify another 400-500 bucks for forged pistons. after doing alot of research i worked out these engines can take roughly 450-500hp, so if i was ever going to turbo charge mine, which WAS the plan to do a year or so after, i just didnt think it NEEDED pistons that could take more than 500hp, thats just not useable power to me!
again from what ive read, so dont take this for gospel, if you are going to turbo a vr6 and want to know the 1 thing to change, its the conrod bolts. i hear ARP ones are great, so i got them.

like i said i havent actually turbo'd a vr6, but that was my plan and i did the full engine rebuild in preperation for that.
let me know if you have any questions might be able to help
i like your plans!

Hate to say this but I'd rather go with Haltech or Vipec than going with lugtronics(which is actually a rebadged VEMS).

I read through AZ and vortex that tech support/communication with lugtronics ie Kevin Black is pretty bad. So imagine yourself waiting for a week or two..maybe a month just for a tech help from him.

Pretty sure the recipe for the power you're after are all in vortex tech builds.
