So maybe I could take a bit of that, and fix it myself, have the painter that painted the car paint it for a bit of cash, and take the rest to get that MK.

Question time (because the more you tell me the more confident I get)
Would you suggest the MK Turbo setup, some ebay intercooler, ebay oil lines, Megasquirt, Wideband, and injectors? I really feel like that's a small list. I mean, boost contoller, bov, gauges, gauge holders, bolts, and other little **** I can deal with, but is there anything else that will stop me from getting the car to go/start up?

The plan I had will still stay though, megasquirt first, then turbo.

As far as this being my only car, I'm 17 and on my last leg of highschool and will have a job very soon (hopefully full time), I have 1300 now to get it started with the ecu, injectors, and wideband, then will use the job to pay for the rest over time. So what I'm saying is I can live without a car, I live with my parents and can have them drive me, or take my grandfathers truck. (I guess I contradicted myself, I do have a second vehicle.)

BOV is a toy at less than 15psi and can wait. The boost controller can wait and can be done by the MS anyway. Another superfluous expenditure for a starter kit. Gauges are not necessary because the laptop will show everything.

Keep it simple and durable. Stick to the necessities.

Wouldn't a boost gauge be something to consider? I don't mean like oil gauges, temp gauges, and whatnot. The car 'has' those anyways.

The toy is what I want, is it true that bov can hurt turbo response?

And thanks for letting me know about the boost controller in MS, how does it work with the wastegate? Do you put the wastegate to the max, then lower it with megasquirt?

Not going to lie, people give you guys a worse name than you deserve, very helpful to noobs.

A boost gauge can be cheap, but it's not needed. I used a $14 one for a while, it just had a terribly shitty backlight. You aren't going to react to a boost gauge in time in overboost, so that's why the megasquirt does that.

I use a cheap ebay blowoff valve, like $30 cheap. If the valve is working right it should not hurt spool. Mine seems to be fine, it will still surge occasionally but it's much better than nothing. It's pretty decent at only opening in high vacuum which is why it occasionally surges. It's firmly closed at idle or better, hasn't given me any problems.

Ebay AN lines/fittings are junk, I use a 4AN brake line for oil and cheap silicone for a return. You can buy T3 hose barb outlet plates and 4AN restrictor inlet plates cheap.

I bought all my **** at once, but I ran just a megasquirt and rx8 injectors for a while. Widebands are cheap and a necessity for megasquirt.

You can still work in a lot of upgrades as you can afford them, so long as you are a sensible person and realize current limits. If you still run stock cooling you can't run full boost back to back on the highway, not for long at least.

You need to read how wastegates and boost control work, because it's totally opposite what you're guessing at.

Alright I'll read up on wastegates and boost controllers tonight.

What do you mean by stock cooling? Do you mean that by radiator and fan? Or deeper into the coolant lines and stuff?

Look up coolant reroutes.

Would you say a radiator is worth getting? My radiator is an OEM one, but less than a year old.

What do you mean by back to back highways? Say I wanted to handle that problem, could I make it run at different boost levels depending on the gear, like can megasquirt do that?
2nd - 8
3rd -10
4th - 10
5th - 2 (so that highway (around here is usually around 90 between cities) it doesn't get as hot?)

Or do you mean highway runs at full ***** over and over. 20-90-20-90-20-90?

I'm sure I could search for this, but my grandfathers graveside is tomorrow and I'm a casket bearer so I'm heading to bed. I really appreciate the help.

Oh we're ******** alright. But we're the merry kind.
We don't reward stupidity, and that is where the reputation comes from. So be it; we have good information. Just do your part and try not to ask questions that are easy to answer with a Google search.

Yes, get a new radiator, but more importantly, do a coolant reroute.
Use the Google machine I mentioned earlier to find this.
Just don't do anything you see Hyper doing
.

MS3X can handle boost by gear, but that is not going to take care of improper cooling.

You telling me my last question was something I should google? Lol gg m8

I'm going to start on this **** soon and think I have learned what I'll need to know to get started. I'll probably have more questions down the road. Next step is either finding a megasquirt for cheap, or just buying it new.

Buy an MS3X.
Other versions will work, but it has more features, and all the support is being focused on it.

My problem there, is I really don't want to deal with building a MS, I just want a PNP ecu as I don't want to have the car sitting there because I fucked up the wiring.

If someone was selling a built MS3X i'd go for it, but if that doesn't pop up, probably not.

What exactly is better about it anyways other than more support? I mean I don't want a list of features, but what is actually going to benefit me being a novice tuner and not going for high horsepower?

There are several vendors of prebuilt MS3 units. Your very own forum admin Brain sells them.
Reverant is another good option who many people go with.
Or just buy an MSPNP from DIYAutotune.
Read this.

A distinct benefit of the megasquirt is the fact that it tunes its own fuel map. I don't remember what else you asked.

I have a $20 Bosch BOV that makes silly whooshy noises. No expensive crap needed. But they are completely unnecessary under 15psi if you are worried about money.

MSPNP2 would probably be the best bet right? Considering I've tried soldering and failed badly. Or is MSPNP (not 2) sufficient? I'm going to contact Brain though for sure.
