Hey all, first post here at VR6oc. Needing some advice and guidance on a build I'm attempting to do - big fan of forum scraping and commentary, wanted to see what you guys think!
The vehicle in topic is a 2008 .:R32, 3.2L VR6 24v CBRA engine, bone stock and at 77k miles.
Let me preface this a little bit; I'm not looking to have a monster modded R32. I'm looking to go a 'safer' route with N/A and gains through efficiency, keeping true to the angry VR6. Classic 'rodder style! Boring the engine a tad, higher strength/larger pistons, longer intake cams for a bit more breath, and water/methanol injection for cleaner combustion and overall safer operating conditions.
Now, I don't have any experience inside of engines as this is my first N/A vehicle to work with, which will be more in my league for starting out. I know how engines work, understand the variables at play, I just don't know where to start looking for parts and people with experience with the platform. I live in California (USA), and have a lot of 'racing' shops around, but they've so far all scoffed at me for not wanting to fully blow this engine with F/I, and won't even quote prices for assembling/tuning what my concept is since I'm "wasting my time" with it. I'm willing to do this myself with all the documentation I can find (preferred), or potentially pay a shop if the price isn't astronomical.
I have gotten confirmation from a hot rod group near me that this is the route to go for N/A, but all of those old dudes laughed after the conversation when I showed them the car I was speaking about. Said they had no clue about parts sourcing or how to really help me, all they know is that it sounded like a good project.
My current plan is this, and I really need some feedback here, or somebody to chime in with experience.
- Raise compression to ~11.5 with 85mm forged aluminum pistons (open to brand suggestions as these are common)
- Snow Performance N/A kit to install before the throttle body (single nozzle, as the intake manifold is great for distributed flow to the cylinders)
- Long duration intake cams, to allow finer mixture of turbulent air/w/m (no idea here as to where to find these)
- Custom tuning or a higher octane map, with a more aggressive timing curve
Brands? Retailers? Current builds with similar concepts in mind? Any classic 'rodders here?
I appreciate any responses, forum-goers! Thank you.

Hey all, Fritz here from the lovely Bay Area, California. Long time VW enthusiast, short time lurker of vr6oc since I've just purchased my first VR6 a couple of months ago.
Had a 2006 GTI for a couple of years, problems made me skip out on it and now my dad has it full time and is putting the money into it.
The new baby is a 2008 R32, only 77k miles on it! My current project, and the whole reason I'm posting here. Check out my signature (soon) for a link to my project/assist thread. I need info on a slightly...different power route than most.
Mom's new MK7 GTI-PE is a fun little look into large turbo application, and the cherry on top of this fun family of VWs.
BUILD: high compression + W/M + long intake cams

Thanks for the responses, guys. I'll be contacting HPA and Techtonics about a custom build it seems. The suggestion of Techtonics Tuning is great, I do like some of their internals. Never heard of them before, so I'm super happy.
Still looking for other info out there, forum stalkers. I know somebody else has tried this build before me...
