I think tonight will be more of a gameplan, inspection and parts list. Honestly, I'm pretty worthless on the weekdays for wrenching because I work manual labour and am old. heh-heh.
But like I said, don't buy anything without checking with Phen or I first. Haha! Phen has saved me probably hundreds of $$$ when I first bought my P5. Then again, he also helped me mod it too so he cost me just as much in fun parts.
The MSP headlights fit the P5 but you'll need to do some re-wiring because they are dual filament bulbs. But they are much cheaper on eBay for the MSP headlights. I have painted and baked mine before and refinished them last fall so we'll take a look at them.
As far as new engine options, there are a few. I would think just another FS-DE and keep it pretty basic would be best. But like the other cats said, they seem to be hit or miss. Kevin (not sure if you met him yet) bought a 1.8 FP for $300 in Chicago and we swapped that in and it's been running great. When I was getting quotes for USDM KL motors they all wanted at least $1k for a motor with at least 100k miles on it. I got my KL for about $900 shipped and it looks like it has 20k miles on it. And there is the FS-ZE option too for about $700 but you'll need to source an ECU for it. But we can research more about that.
I'm stoked to come over and check it out tonight, man.
edit- and my FS-DE will be for sale when I swap but that won't be till May or so. ANd it's got 132k miles on her. But still runs great, we'll go for a ride tonight. But no pressure to buy it.
