My first REAL SCARE with the Boxster! need some advice..

[CrisZenithBlue]

some of the particles were metallic some looked like copper.

i've decided to go with a used 2.7l so i bought a 21k miles engine from Cellkid and it's gonna be on its way soon.

need some more advice while that is being shipped. this is a great time to do some upgrades and preventive maintenance on it so here's what i'm thinking:
- buy a new S model oil cooler (wont touch a used one that might come from a blown engine)
- new WP that i already have (stocking up on parts) and regular thermostat (that i already have)
- will grab the AOS from my engine, it had 15k miles on it so i dont feel i need to replace it now
- Vertex IMS bearing (they are close to me and i can get a good price on one)
- i have TopSpeed cat delete pipes and Fister exhaust. why not add some aftermarket headers while at it and make a bit more power. can anyone recommend a cheap-ish set that will also delete the primary cats but wont leave a CEL on? not fabspeed though.. i know those are way too expensive. i'm in FL so no emissions test woohoo!
- i just put a new MAF on my old engine so will pull that from it
- new stock air filter
- new plugs and tubes (engine is old in years so plastic is probably brittle)
- should i also get new coil pack? maybe at 21k miles they wont be bad but still.. plastic and age
- was thinking of getting a lighter flywheel and make it a bit more revvy.. what do you guys think? what's a good brand/clutch set?


what else should i keep in mind? i dont want to go to crazy and murder the piggy bank but it's a good time to make small improvements.

thanks in advance,

Cristian
