Finding a DSM was much easier (to find)/cheaper out of state rather than buying in Montana- I took the chance and bought one while on vacation- still no regrets!

On vacation I bought the car in New Mexico and traveled straight home to Montana. Before leaving the state, turbo failed. No tools on vacation :)! Well the PO had a nice expensive OEM Evo316G on there, that I paid dearly for again. Something like a 3k total repair bill from the shop that I was at the mercy of. Yup I paid, I really needed to get back to work, boss was expecting me back. Fast forward just 101 miles before home and timing belt fails :). Oh well, I had AAA, free 100 mile tow. Drop it at the house and the guy writes a bill for the one extra mile. Must hate DSMs.

Yup it's been a money pit but it wasn't going to be a daily driver. Yeah they're cheap cars to modify, just don't buy out of state unless you got some extra cash.

So I rebuilt the whole setup minus the brand new turbo. I first wanted to get a feel for the car and how to tune before modding. Well one day, in the driveway I took something apart and ended up waiting for a part. What the hell lets fix this other thing up while I'm waiting. And delete this. And rewire that. Notice something? Well that pattern never changed. I haven't driven the car 3 months total and going on 2 years owning it. SO, currently, I'm giving it an entire wire tuck, redesigning the shifting setup (full ball bearing/bronze bushing system), redesigning cooling system (expansion tank vs overflow, like a GM), possibly DIY twinscroll manifold for an HX35 I got for free, among typical things.

I'd like to have the car widely known one day -when time permits to complete the project, and who knows maybe sell it after to get 50% of the money back on it ha! I'll try all the kinds of racing one day but I'm fairly certain I'll still like working on the design of -and custom building of cars over any of the possible end results like driving the damn thing or racing :)
