i plan on, when i get back from deployment, starting a turbo project on a 2004 toyota tacoma 4x4 trd. i will be getting the cx kit and i was just wondering will i need to upgrade the fuel system/ECU? will i need a piggyback, i can only find injectors specifically for the trd supercharger which i have already had the argument of turbo vs s/c. also with 11-12psi, i know the kit comes with an 8psi BOV but i will be replacing the spring, will i need to build the bottom end (i.e. forged lower compression pistons, Rods, and Crank) if so where is the best place to look for those components. Thank you very much

If you are going to build the bottom end, LC Engineering has all the parts for that. They sell a forged crankshaft & chromoly rods with ARP rod bolts & also CP forged pistons & they can make them any compression ratio that you want & if you ask them they have teflon coated bearings that they don't have on their website & they also have toyota style fuel injectors up to 650cc & some smaller.

So i will need to upgrade the fuel system what size injectors do you think im going to try and get 10-12 psi?

You would have to ask the guys that have turbos. Mine is only supercharged & right now I have 6 Bosch 318cc fuel injectors with a Walbro 255 LPH in tank fuel pump & a Walbro 255 LPH in-line fuel pump. I'm building mine for drag racing only & I'm going to the 650cc fuel injectors & I have a Haltech Platinum Sport 1000 ECU so I can tune it for what ever size of fuel injector that I use.

I ended up using the FIC6 controller and URD port injector and a Felco 255lph pump (cheap ebay pump).

Careful with changing primary injectors; its can be difficult to tune low rpm's/idle if the injectors are too big. With the URD port fueler, you only have to tune boost and let the stock ECU do what it does best for daily driving.

My truck will not be a daily driver & it will be for drag racing only & it will be highly modified & also will be running a 2 stage nitrous oxide system along with a methanol injection system using pure methanol mixed with 10% nitromethane.

Comment was directed to the OP ;)


Still waiting for your build.... :D

First off you have a bit to learn, I would do some research before jumping into anything.

I will go in order of how you asked them.

You will need to upgrade the fuel system and ECU if you want to make more then ~200-220whp as thats where the stock injectors max out. Injectors are not supercharger specific, if they fit, they will work with whatever.

That said Andrew is right, extra injectors are much easier to deal with when using a piggyback vs messing with the primary injectors. Only issue I have with the port fueler is that it forces you to use the stock intake manifold, that should be a must change piece with a turbo IMO. You might be able to use it on the low plenum mounting point though.

The BOV has nothing to do with the boost pressure, in fact you would be best to not install a BOV at all. The wastegate is what control the boost and you can easily change the spring in it or add a boost controller to get whatever boost you want.

You will not need to worry about the engine itself until you are making ~400whp+. The thing you will need to worry about is the automatic transmission if that is what you have. That will blow with only mild amounts of extra power.

Ok & I agree that for a daily driver to large of injectors would make it idle rough.
Not the case at all if you have a standalone. You can make 2,000cc injectors idle like stock with modern injector tech. I know of a TON of guys doing just that.

You do pay extra for that tech though. For a V6 a rule of thumb is the injector size in CC is roughly what you could make in WHP.

So a 500cc injector would be good to around 500whp on gas.

Say I wanted to get just try 220hp for starters which is where you said the stock injectors max out. Could I do with everything stock? How much boost would you recommend?

Texas_Ace I believe sold his 4Runner.

If you mean 220HP at the wheels, you'll be nearing the top end of what the injectors can do. You can push injectors to 90%+ duty cycle but at that point they basically are just spray nozzles that are on non-stop and are very hard to tune. The 5VZ-FE dyno's around 148HP so that's pushing about 70HP higher than what it came with. There are drop in options available from other Toyota/Lexus vehicles.

Are you looking at running the turbo system with a piggyback system?
