Walk through of a turbo build.

Building a turbo motor is not as hard as it seems. Yes, there's a lot of parts you need, but there's also things that are nice to have but not necassarily needed. Before you begin you need to know what your goals are and what you're working with. Make sure your engine is good to go and then start your parts collecting.

As an example we'll start with a 3.0l V6 engine. We're going to run 7psi boost.

First, the shopping list:
A turbo - you don't have to have twin turbos just because you have 2 cylinder banks. In most cases one large turbo will perform better on a V-type engine the 2 smaller turbos, it's also more simplistic in design. A mitsubishi 14b turbocharger from a DSM would suit our needs but we'd be pushing the limit with it beyond 7psi. It's got an internal wastegate too so that just eliminates another part needed later.

exhaust manifold - you can use a stock one, you'll just need to modify it so you can mount the turbo if you don't use a Y pipe. it all depends on your application, you can also get custom made turbo headers too, this is the preferred method. We'll say we're gonna use a Y pipe and mount the turbo towards the back of the engine bay near the bottom of the engine but still in the bay.

exhaust piping - if we're running a single turbo we need to route the exhaust gas from both banks into the turbine of the turbo a custom y pipe would work this just really relies on your engine bay layout.you'll also need a downpipe from the turbo to hook the exhaust up to. this should also include a dump tube for an external wastegate.

Wastegate - if you need an external one, you'll need to modify your exhaust manifold to install it. So for a modified stocker I reccomend an internally gated turbo, use an external gate for custom jobs.

intake piping - basically a CAI will do the trick, save some money make your own, just don't use PVC piping. Engine temps will degrade the plastic and cause it to break, that wouldn't be a pretty sight. Also be sure to use silicone couplers, cheap rubber degrades easily as well, silicone stands up to the heat better.

Piping from turbo to intake - again can be made at home.

Blow-off valve - not needed if you have an automatic, but mandatory if you're using a manual tranny. Relieves the air pressure between the turbo and intake. operated by a vacuum line. The best one for cheap is off of a 1g DSM and is reliable beyond 15psi if modified, I've even seen guys run 20+

Intercooler - charge cooling of any kind, whether its an intercooler or water/alcohol injection is a good idea, but not mandatory if your running low boost. go above 6-7 psi, and I wouldn't bother trying to hotpipe (running without charge cooling)

Injectors - you're adding more air, you'll need more fuel. Plain and simple just make sure you have some kind of management for tuning.

Fuel Pressure Regulator - there's hundreds of em out there just make sure you pick a good one. You could also get a fuel pump with a higher flow rating.

Fuel management - the best (in my opinion) and most known on the market is the Apexi S-AFC. It will work with your MAS or MAF and ECU so you can control the amount of fuel the ECU injects into the engine to fine tune and get a smoother running system. You could also go with a standalone ECU like the Megasquirt, SDS, or Greddy E-manage, but those are highly advanced and require a lot of time to learn how to use properly.

Boost controller - you can make a very reliable manual one for about 7 bucks with parts from Home Depot Performance Shop... or you can spend big bucks on a premade manual or an electric. this will control the amount of boost your putting into the engine.

ignition - you need to run spark plugs with a colder temp range, bigger wires are always good too. You may also need to adjust your timing as well.

Various Small parts - vacuum tubing, oil lines (possibly coolant lines, depending on your turbo), and line tee connectors are always good to have around. You may also need to find a way to modify your oil and cooling system so that you can connect everything.

a full up engine build is not necassarily needed if you don't plan on going too high with the boost. Just besure you time it right and eleminate all detonation and it will run reliably for years. The hard part is actually installing it.

If you guys spot anything I missed in my articles, or typos call me out and I'll fix it. It's not my information, it's ours.

good to see people out there who like the turbo setups. I get tried of guys telling me a supercharger is better. Technically, a turbo is more efficent, but it really come down to what you want out of it.

I'm thinking of doing a twin turbo set up running side mount intercoolers and stock turbos from a 300zx with the stock recirc valves but well see if it ever happens or not but it'd be pretty sweet.

Wha is the stock compression ratio on the 5.2 motor??

Because I know (typically) high compression motors + boost= trouble. I know you can safely run low psi, but why boost if you can't up the boost. Boost is as addicting as crack, idk how people run low boost. All the cars I've worked on came to me boosting 8.5 psi(stock) and left boosting 18.5 on hi and 15lo. I'd wantto run like a 8lo 14hi. Idc if I need intercoolers along with meth

I'm looking at engine swap for my Dak and when I get into that project i was going to go ahead and pipe it and set up for a twin turbo setup...
