I didn't know they were naming turbos stage x now. What marketing schemes Will they think of next.

For a turbo upgrade you Will need the following.

Turbo: price depends on turbo.
Intercooler: depends also. Fmic or tmic? Roughly $400-1000.
Fuel pump:$100
Injectors: about $550
Tune: about $500

You have only had it 2 days and already ready to go this big? Is it up to date on service? You would need to talk to a tuner and not us to decide exactly what parts Will work for what your goal is and what they recommend cause in the end they Will be the one that's gonna make it work.

285 is an arbitrary number since crank numbers not from auto makers are mostly made up. It's about 230 whp. Stage 2 and stage 4 turbos don't exist. This isn't Gran Turismo. What specifically did you have in mind for a setup or power wise?

You already have a stage 2 set-up.

Stage2=downpipe and tune.

1. What is a stage 2 turbo?
2. Stock BOV? KEEP IT!!!
3. Stock intercooler? Stick with a top mount. Go bigger and used if you can. Front mount can be a lag monster.
4.& 5. That will be fine.
6. Waste of money at this point and a good sign the previous owner didn't know Jack Squat! This should have been a last mod on the way to 400 hp. Not a 1st mod to hit 230WHP. As long as you tune for it it can't hurt. A good coat of wax will give you more ponies than that thing.
7. Get a real tune. Open source is the best bet. I wish I could find 93 oct. 91 is all I can find. If it is going to be a daily driver I'd go with a tune that uses the highest best available oct.
8. Unless you track it this is for show.
9. Kartboy RULES!!! Anything less is for fools.
10. Sways and end-links would have been money better spent.

My advice to you is get this engine checked out first. Blackstone oil analysis and a compression check come to mind. I see a few red flags here. Take your time. Do LOTS of research and keep in mind ,this car has been out for a long time. We know what works by now.

And give us some pics! Bugeyes RULE!!!

All right, where is the distributor cap? I need to find the #1 plug wire to hook up my SUN machine.
