Default Custom Turbo

Has anyone made a custom turbo build for the L98?
I'm thinking about making one...

There aren't many out there. LCvette and MNvette have designed their own systems, but both are LTX cars if I'm not mistaken. JoBy's car is L98 based, but I'm not sure what accessory set up he's using, or if you'll run into problems using the stock L98 intake where his car is using a modified stealth ram.

As soon as I find my money tree, I plan to go twins on my L98 car. I have it all mapped out in my head, and I'm pretty sure I could make it work. However, mapping it out in your brain and the actual build are completely different, lol.

It might be easier to find an LTX accessory system and use an electric waterpump. If you do that, there is a pretty big hole on the passenger side that a turbo will fit it. I believe both MNvette and LCvette put their single set ups there.

I have taken quite a few measurements and have a pretty comprehensive list of parts if you want to get together via AIM or something and discuss ideas.

I'm waiting on my money tree as well, lol. But I think it'd be cheaper than buying a $5000 procharger system, plus I'd be more satisfied if I actually did all the work.

I've been reading pretty much everything I can about turbos and building the system. The only things I'm worried about is the timing needing to be changed, the engine needing more fuel, and tuning/boost levels. So in reality I'm still a rookie and have alot of work to do before I can start buying parts. Yeah I'd be up for discussing.
