Hi guys. Thank you for all the feedback. I appreciate your willingness to provide inputs.
I come from JDM naturally aspirated platforms. I currently own a highly "personalized" S2000 that I bought new in 2007 and intend to keep for ever. I have pretty much done all power mods that make sense and spent money on handling and braking mods to my exact specification. The car weights 2650 pounds with me inside and 1/2 tank of gas and is a joy to drive. I was patient in slowly accumulating performance parts and goodies including lighter parts (can be extremely costly), often waiting for sales to get the right part or accumulating parts as they became available used. Generally speaking, every aftermarket part on my car can be sold at 80-150% of price I paid. Having a really long term view allows me to take advantage of arbitrage opportunities to buy low and enjoy until some day when I will get rid of the car.
I went down the typical stage 1 -> stage 2 route with my MK7 GTI and have been sorely disappointed and underwhelmed. I can and I should but I am not going to bitch about some of the engineering choices that VW made and the garbage marketing echo chamber the larger aftermarket support companies have created. I've decided to go the hybrid turbo route and focus on building a car that I would be happy to own for many years and miles. I want to build a car that I like so much that I would refresh/upgrade the engine when the time comes (assuming no catastrophic failure). However, I want to be very patient and smart in how I accumulate the parts that I will surely need to support big turbo and nice to have parts since all will suffer from huge depreciation.
So back to aluminum front subframe. I am absolutely not going to buy this part new. I would like to keep the part cost down around $250-300 because it doesn't do much and I can make the upgrade anytime, independent of other mods. I contacted over 30 salvage auto joints and autohaasparts and another place located in NC seem really promising.
If any of you guys have hybrid turbo set up, I would love to hear your thoughts regarding what supporting mods are proven to work.
Best,
J
