I'm looking to turbocharge my 97 f150 4.6 liter and don't even know where to begin.... Money is a big issue.. lookn to turbocharge under 2 grand and achieve over 100 hp.. Can anyone help me? All ideas are welcome....

Thanks TJ

 

If you can pull it off for under 2gs it would me impresive, you cant find a kit that cheap so the only option is a custom set up so figure 250 for the turbo 400 for a KB boost a pump, 350 for injectors then 1100 for custom tune for ECM( depends on whos doing the tuning), and then there's the BOV dono how much they run and all the piping and exhaust work that would be take ridiculous time,also you probably want an intercooler and those arnt cheap, but if its a hobby and sounds fun go for it. also there are many different ways to do things so i could be wrong.

 

well i jus purchased a t70 and oil lines... what should i get next?

 

Is this truck your daily driver?

 

yes it is. im only in highschool still can't experience the two car luxury lol

 

Dude your opening a big can of worms with this project, your truck could have some serious down time before you complete this project. First thing i would do is find a tuner with a dino tell him what your planing on doing and ask how much for a costom tune, also do you know what the wast gate is set at for boost with that 4.6 i wouldnt run more than 6 to 8 psi, then after you figure all that out ask the guy doing the tunning what he would do for a fuel set up, like bigger injectors new fuel pump, this is only a start and for sure before you start this project make sure you have all the parts to complet it. also ask the guy for sugestions on were to mount the turbo and how to run the piping and i realy hope that you are very good at MIG and TIG welding because your going to be doing alot of it, it can be done but it will be an a$$ load of time and labor.

 

ok thanks man

 

There are several threads on FTE in this section about fabricating your own turbocharger system for various engines. I don't think any of them speak to the 4.6L directly an engine is an engine is an engine and it's a matter of sizing the turbocharger correctly for a given engine displacement and effective RPM range. These are decisions made up front, then once that's done you start welding up your exhaust manifolds, plumbing the intake, and so on.

If you acquire parts through trade, ebay and junkyards, you can put together a system for much less than two grand. But keep in mind after you fabricate and assemble everything, you need to tune the EEC (the EFI computer) so that it understands the concept of boost and doesn't choke to death on the radically different-than-stock data.

Generally, you need software, a programmer, a J3 adaptor with a ZIF socket, and a variety of other things. Most importantly, understanding and patience.

And MeanV10 is right - unless you have a spare 4.6L engine to use as a guide to fabricate exhaust and intake on, more than likely your truck is going to be off the road for a while these steps occur.

This is why my twin-turbo 500cid stroker project sits on a run stand in the garage - I can work on it as I have time and money, and the original engine remains in my daily driver and I can still use it. Burning lots of oil yes, but it runs

 

i jus got a t70 turbo and a type RS blow off valve... whatz next?

 

Honestly? A "time out" and some planning.

You're putting the cart before the horse and a 1000-1200cfm turbocharger (T70) is grossly oversized for your stock engine.

You need to figure out a realistic power goal, rpm range, and size your turbocharger for those figures based on the amount of boost you want to add.

THEN you buy the turbo
THEN you fabricate the manifolds
THEN you install the intake plumbing
THEN you tune the vehicle.

Intercooler or not?
If yes, water or air intercooler?
Alcohol or water injection?

Where will the turbos be under the hood? Next to the engine's heads? Over the wheel wells? Next to the side of the back towards the back? In front where the accessories hang out? Closer to the radiator support or possibly in front?

Where are you getting the manifolds from? Are you making them? Are you having them made?

Where are you going to source the silicone hoses from? How many bends will there be? Inside diameter? Will they be reinforced or not? What clamps will you be using?

I seriously recommend you purchase Corky Bell's "Maximum Boost" book to get you started in building a mental foundation of what's involved.

Turbocharging an engine is significantly more complicated than buying a random turbo/wastegate and sticking it in the engine compartment with duct tape.

 

Maybe this will help. Alot of money.

thanks for the help bigtime. Well i'm gonna probably use the t70 and type rs blow off valve.. can i fabricate those to fit my f150? what to buy next?

 

I'm not telling you what to do but Frederic knows his stuff about turbo systems. Just search for post by Frederic. You will see he has alot of info on turbos.

 

I have a universal twin turbo kit brand new out of the box. Includes all piping everything you need except for the exhaust manifolds which you can cut a set of headers and moch them to fit, to the flanges on the turbos. Please feel free to call or text me at 2893310012.

 

Guys probably married with kids by now lol
