[@Saltyoldguy-]

Just a note on the pistons: the reason they blow ringlands like that is due to the very tight stock ring gap. Lots of guys havs really good results using stock pistons with wider ring gaps in the high .020" and low .030" ranges. With the stock gap of .015" pump gas is just too much heat for them at the 500+ mark, and they but together.

[@COMotorsports]

Agreed (to an extent lol), we've done it and still had issues. It really comes down to the fuel being used. The real answer is keeping the knock out.

[@Saltyoldguy-]

@@COMotorsports For sure. I do see a surprising amount of people running genuinely 600whp through bone stock motors on full e85 and doing it for a long time. Whether or not they have blown ring lands and send it anyway I'm not really sure lol. But like you said, the main key is keeping heat and knock away.

[@Aladinscave]

Fully agree with you, running boost on std ring gap is playing with fire it WILL break the ring glands it just a matter of time even on a forged piston 🏁

[@byronn.2885]

The VR6 is one of my all time favorite engines. They just sound so good with a high flow exhaust.

[@sursomsatan1225]

Way better than any of the popular i6 engines

[@lorddrako1990]

Now we're in my wheelhouse 💪. My stock rods lasted until 30psi, 20* of timing, on e85, and borg s366. So approx 600-700 wtq is the limit or stock rods. Stock pistons are good to about 600whp with them being gapped to roughly 0.025". Anything more and you need aftermarket forged. When tuning, keeping it a point or two on the rich side and will save the hot cylinders. A head spacer/low conpression pistons are only necessary when using pump gas. E85 does not need lowered compression so you get to keep low-end torque when using corn juice. The mk3 12v vr6 has a FIBER head gasket and MUST be replaced if turboing. It will not hold pressure well. While the head is out, put new valve seals in and HD springs.

[@williamhall7446]

[@patriklenck1735]

​@@williamhall7446 3.6 is direct injected with high compression. Not the best recepie for a reliable turbo build.

Good video. I am about to embark on a 550WHP (approx) 3.2 into a 2001 S4 B5 manual. Learned a lot and will do rods, pistons and a good head. Flywheel and adapter is probably the single biggest $$$. Probably go with Holset Cummins turbo at around 18-22 boost. Pick N Pull has my motor for $349CDN complete from Toureg.

[@tptrsn]

Great video! Question though, have you guys actually seen any situations where the stock rod bolts were the initial breaking point in a turbo VR6 build? The reason I ask is that theoretically speaking, the instant of maximum strain on a rod bolt is at TDC on the exhaust stroke. When you add boost, the backpressure in the exhaust port in front of the turbine wheel, and the incoming boost itself depending on overlap, actually cushions the piston at TDC on the exhaust stroke, thus reducing strain on the rod bolts. Presumably you might also add to the top end of the RPM range with the help of boost, so that adds strain to the rod bolts, but I don't know at what point the strain forces actually become higher than they were with the factory N/A configuration. I suspect that rod bolts really aren't necessary at all in a turbo setup like they would be in an aggressive all-motor setup.

[@ChastonPierce]

Just want to add, you can use stock head bolts with a head spacer. HPA uses them even with a 5mm head spacer plus 2 full gaskets, and have had no lifted heads on their 780ftlb of tq builds. ARP head studs should be a requirement for 800+.

In regards to the cast cranks, been in the facebook groups for almost a decade now and have seen them fail in cars. Usually upwards of 5-600+ to the wheels and experiencing detonation. Also seen a lot of experienced tuners use cast cranks in close to 4 digit builds perfectly fine. It seems the cast cranks just aren't able to hold detonation very well, which still isn't good but is different than "you can't use these ever."

Interested how you deal with the timing chain for the cams...

I know on the HPA kit where it drops the CR to 7.5:1 they supply a chain with an extra link... is this something you do or anything you would recommend to do to mitigate the inevitable chain fun and games?

You mentioned head spacers but when using forged pistons that lower compression is a head spacer still necessary? I guess a better question would be: what compression ratio is recommended for pump gas as you mentioned?

Lower comp pistons, no need for headspacer. It's just used to lower compression.

​@COMotorsports The head spacer is a great option though, as it makes the VR a non interference motor. So maybe take that into account when making your purchase.

Is the two head gasket route even an option? I'm still naive and inexperienced so thank you for answering my previous question you guys are really cool

[@COMotorsports]

It is possible to stack gaskets but it's just more room for error. If you look at an MLS gasket you will see it's 3 layers. The middle layer gets taken out and the spacer goes in its place which replicates a stock gasket, just thicker.

I drove maybe 5 months and couldn't get the car into gear. Stock 02m gearbox and the pressure plate was digging so bad it left indents on the housing. I had it diagnosed and they suspected crank walk. Wear spec is .30mm and I measured .38mm. Would the crank walk cause that much damage to the gearbox or is that more a clutch fitment or install error?

So if you were planning on forged pistons, would it make sense to just get lower compression forged pistons and not need a head spacer?

[@Saltyoldguy-]

IF you need the pistons. Otherwise stock pistons are more than adequate for most 500whp builds

[@E36_kidd]

it depends on on the fuel you plan to run

[@BEYTEK]

600bhp mk5 r32 snap crank. 2.8 crank to make an R30 is the way to go here in europe

Can you share failures?

[@dejanmeki]

I have 07 Touareg 3.6fsi would like to put turbo and have 500- 600hp of it 😂😅....

[@COMotorsports]

Do it.

[@dejanmeki]

@@COMotorsports what's the roughly price tag for it ?

[@COMotorsports]

@dejanmeki well there is no kit so your making a lot of it yourself, and there will be tons of billet parts required to make the parts needed. Way more than the vehicle is worth, so if that scares you, then time for another project. Lol

I kinda disagree with what was said in the beginning. Yes knock/detonation is caused by poor tuning (this is why having a standalone is important. Failsafe would’ve saved it) but forged pistons are not gonna stop knock/detonation. I’ve seen forged blocks go just as quick. The weak link no matter what will always be rod/journal bearings. Stretched rod bolts. What I disagree with is the HP numbers. I’ve seen 800hp with just spacer and rod bolts. All on a 12v but that power is useless in a FWD car hence why most who are at that and above are usually awd. I don’t say this after building one VRT. I’ve built plenty in my 30+ yrs in the game. 23 as a shop owner. I have a VRT that’s been seeing 30 lbs of boost for 17 yrs without opening it once. Went through a few turbos and a few trans. That’s due to a good build and good tuning. My point is don’t think having forged internals with prevent these things cause they won’t. Detonation don’t give a shit what you got inside. I’ve seen a few broken ringlands on forged pistons. I’ve seen holes burned straight in the middle of the piston. It all comes down to tuning and setting the failsafes so it doesn’t get to that point. What they do is allow you to set your comp ratio better then a spacer. With the spacer you only have 9:1 & 8:1. Pistons you can do 8.5:1 and so on. It also allows for deeper valve pockets for those running big cams. (288’s and bigger). Keep up the good work guys. About time you’re touching a man’s engine. Not that crappy 4 cyl junk. 😁

We're talking to 99% of the people that are on YT so although you disagree these are good rules to follow for the average person. We've seen stock VRs make 1000whp that doesn't mean it's partial for the average person. Guys doing stuff like that are much like us with the 1.8t stock engine that we made 600whp. We have the means to get there safely. Regardless of which engine or how many cylinders yes of course knock/detonation will kill all of them without question.

[@nonsense0233]

if you go forged pistons do you need the spacer?

[@COMotorsports]

No. Spacer is just a cheat to drop compression. Aftermarket pistons would be spec'd for the application.

Ferrari have a brand but they build (like all Italians) beautiful junk. Thanks it. No engineering prowess what’s so ever. Any real car engineering company knows this.
