If this is going in a mk3 mk4 jetta or golf, ill say this because I had a turboed mk4 gti and I fabbed everything. clutch will slip, axles will break, quaife is 800 plus a pain to drill out ring gear rivets, 100 for arp diff gear bolts, intercoolers are a bitch to fit just like any other car, tires are expensive, for 600 horse you WILL NEED motor mounts, especially with how fast a hx35 will spool, every car that isnt turboed from the factory will always nickle and dime you not matter how cheap or expensive your budget

Yeah, is this longitudinal or transverse? Either way, what he said... 600 WHP in any car is going to need a lot. Oh yeah, forgot the injectors, fuel pump, head spacer if you're going to drop the compression, cams (don't know if you're changing them but I don't know how well stock N/A cams work with VR6 turbo engines) exhaust, exhaust manifold, external wastegate, brake upgrades to stop the thing, assorted brackets, clamps, lines for the turbo, PCV system rerouting and catchcan and I'm sure there's about 10 other things that I forgot that someone will add.

Oh yeah, then there's the issue of tuning it. Standalone from 034's about $2000 + dyno time to dial it in unless you can get a custom tune done on the factory ECU. In which case you still need the dyno time.

Don't get me wrong, I'm all for crazy projects and builds, it just won't be cheap. It'd almost be cheaper to do a twin 28RS elim 2.7 S4. Or a Tial 770 build.

Been done plenty times in a B5 A4/S4, even more people attempted to do it and quite. Be ready for things to break often if your plan on making 600whp.

VR6 might be cheap, the HX 35 might be cheap too. But everthing else to get it in the car and running will break your bank.

Hx-35 would be an excellent choice. If I were you I wouldn't shy away from an hx-40 even. Plenty of 4 cyl guys are running hx-35's. If you're going vr6 then I would look into the hx-40.

My buddy keeps telling me they "dont know the peak hp of the turbo" Well idk about that but I bet the turbo would be amazing on a VR6!

BW EFR would be even better.

That's true. A $500 vr6 swap. You're on the right track, but you left out exactly 98.7% of the parts necessary.

Well I wouldn't worry about that. I mean you don't NEED them, ... wait... you do.

How's the spool up? Do you have a log that shows boost/rpm?

sounds like a huge endless list to complete this goal, i would plan on spending at least 5k to do everything the RIGHT way

what you guys dont know is everything has already been replaced. im running a pc 16 k04 now. i know axles will go a lot. i want some stern track density mounts all around tho

$5K? That might get you half way there. There are people that spend $10k on that setup and gave up before they could finish.

Did you just use a k04 tune and supporting mods as reason why a VRT in an A4 would be a simple swap?

I dont, the motor is now going in my a4, but in my gti I would hit 18 psi at 4200 rpms

ditch the hx35 and get something bigger for a vr

hey dont forget the $500 vr6 engine cradle for the a4 chassis.. but honestly i wouldnt do it unless i had a vr6 already.. and a blown up a4..

Honestly, the vr6 and the turbo are the cheapest part of a vr6 swap.

Or make your own if you have access to a welder like Spanky does/did.

I was thinking of doing this when I blew my motor but it's too expensive for me right now. I already have a 12v vr6 block, and heads so I thought it wasn't going to be too bad. Here's a little build sheet I made couple months ago. That's missing a lot of things btw, also thats all internet pricing. Theres some stuff in there you don't really really need but I always like to do it once and do it right. If you plan on building a VR6 you better have no budget, unfortunately most of us do.

Did I read this right? the car currently has a ko4 and matching software, so it is all set for 600hp? just buy rods and a turbo?

here's your sign

god, point being is the groundwork is laid, and to the numbers guy, my hx ws like 150 out of a wrecked cummins, my tune is 300 because my friend owns all the goods including a mustang dyno, rods are cheap from scat, manifolds are 200 from atp, i dont give a fuck if it cracks, its 200 bucks, thats for starters, get your shit right, the cradle, i wanted to learn fab work more precisely. what a bunch of fucking douche bags. my whole drivetrain is rebuilt, short of a clutch which i already know. have fun playing ookie cookie

We aren't douches, we're realists. Because realistically, you're way in over your head if you think you can just slap shit together and it will work.

Irony.

Just put the HX35 on your 1.8t. It will save you $10k+ and 6-12 months of hating yourself.

lol
rods are $600+,
atp manifold is not $200(clones are but not atp)
how bout injectors?
software?
intake manifold?
clutch/flywheel?(you now this is custom right?)
oilpan?
etc, etc, etc?

Im not trying to be a dick but nothing you did preps the car for a VR6 and you dont understand that, prove us wrong and keep us posted with pics

i was oversimplifying, i know that by no means will it be easy, and i think that it came across i thought it was going to cost nothing, im looking at a bang for your buck perspective that....for the money, a vr6 will be more reliable than a 2.7 with k04s or 28s. also that i can make close to the same (not saying same, but ballpark) whp to a tial kit or 28 on the 2.7. i have help on parts and a tune because a good friend of mine owns a place in durham nc. injectors i have siemens 630s and an ecs adj fpr. mani will be atp, which are like 200....i know people with them. clutch / flywheel...according to blackforest there is a bell housing adaptor for this which is reasonable. pan....no clue. and you are correct, scat rods will be 600...im not fucking stupid and i know the road ahead, but this is much simpler and much more reliable than other options

Honestly, if you're looking for simple, this isn't it. If you're looking for a long term project, that you will spend days and days and days fiddling with the smallest little thing simply to get it to fit, or even come close to making it work, but then have to go back to the drawing board and start over, then this is it.

By all means, go for it. Read Haenszel's, NYCS4, BigBoost's build thread and you will get a better idea what you are getting into. We do need more B5+VR6 cars around.

need some engine mount brackets made?? PM me. :)


and also an HX35 with the oem 12cm housing hit 25psi by 4300 on my 8v and that was just SILLY :) 375whp and 365wtq...WINNING.

jettaglx91
05-02-2011, 04:57 PM
Simpler then a 2.7T? not a chance

More reliable then a 2.7T? well the vr6 in general will be but the swap part totally changes that, it will all be based on your skills for the install

again ATP manifolds are not $200 unless you are getting one used

You keep saying you have help on tuning but what are you tuning? you have to purchase something to start with?

and the bellhousing adapter/flywheel I think its about $1000 and that doesn't include the clutch

and you are not gonna make 600+hp on 630's on what Im assuming is a 12v

wildbill
05-03-2011, 08:39 AM
its a shot in the dark
i cant say the shop, but the guys name is evan
and we were going to start with 630s and go from there
