Few turbo driveability questions.

[ShiningBuick 10+ year member]

A buddy of mine picked up a turbo setup from a 2.2eco today for cheap, kind of an impule buy, but he's going to put it on his 2.4L in a Sunfire.

I did some research so far, and now I'm curious on a few different things that I ran into.

it's a T3/T4 turbo, reletively small intercooler, and and I don't remember who makes the wastegate and BOV. Right now he's planning on running around 5psi for starters, so he doesn't blow stock internals hopefully (he already said if he does he'll upgrade though).

So installing will be the easy(er) part it seems, but once it's in I'm lost on the little details.

Lets see..

2 Bar Map sensor? Will he need this guy? Will this work if so?

Wideband? Sounds to me like this is an air/fuel gauge? He's got a simple airfuel gauge, does he need this to go along with it?

Injectors? Are there any bigger injectors that fit directly on that are recommended?

Intake manifold.. keep it stock or will it need an upgrade?

Boost controller? Any recommended brands/ setups for this?

PCM.. will it need a an aftermarket one? just a reflash? Is this going to be possible to tune with a laptop/ obdII/ something or is it going to need professional help?

Any other stray sensors/ lines that need to be relocated or anything?

Also, any recommended engine upgrades right off the bat? Cams?

Sorry if I'm ignorant, this is new to me. I tried searching and these are the questions I was left with.

Also, don't bother saying to build the motor up, he's dead set on putting this in, THEN dealing with it once stuff breaks.

I dobut the exhaust manifold will work. Does he have the LD9 (non-ecotec) or the 2.4 eco?

I'd check out http://www.j-body.org/

T3/T4's are good turbos. I'd check for any shaft play and have it rebuilt. Tial BOV's and waste gates are nice.

He should not need that, but I'm not certain on that motor.

The one he has should suffice.

Injectors? Are there any bigger injectors that fit directly on that are recommended?

Bigger injectors are a must. You're putting more air into/out of the engine, you're going to need to give it more fuel.

Intake manifold.. keep it stock or will it need an upgrade?

Won't need to change that, stock is fine.

You can make a home made boost controller, or buy one.

Take a look at this

Not sure on those motors, but on Hondas they'll convert the car to a OBD1 ECU for greater tuning capabilities

Cams not needed, but it'll make a little more power.

He could run into one of the two problems. He can blow a connecting rod right out of the oil pan, which isn't bad, just replace the rods with forged internals with a nice set of pistons. The other thing that can happen is throwing a rod through the side of the block. Then he's going to need to buy/build a complete motor, and start back at sqaure one.

With those questions, I see stuff breaking quickly.

With that said, I'll try to answer with the best of my ability.

2 Bar Map sensor? Will he need this guy? Will this work if so?

His car already uses a map sensor. I don't think he'll need an upgraded one with the amount of boost he is running. Also, link doesn't work.

Wideband? Sounds to me like this is an air/fuel gauge? He's got a simple airfuel gauge, does he need this to go along with it?

A wideband refers to the O2 sensor. He will need this in order to tune the car properly.

Injectors? Are there any bigger injectors that fit directly on that are recommended?

You probably don't need injectors with only 5lbs. of boost. With that said, you may want to research the types of injectors that may be available for his car. Tuning them is not going to be fun. Usually an upgraded fuel pump and fuel pressure regulator is all that is needed.

Intake manifold.. keep it stock or will it need an upgrade?

Stick with stock. I'm pretty sure you'll have to have one custom made if you do decide to change it. I believe Sunfires have pretty short runners on the manifold anyway. You could always port it if need be.

Boost controller? Any recommended brands/ setups for this?

Electronic boost controllers are more accurate. The Greddy EBC is a really good one.

PCM.. will it need a an aftermarket one? just a reflash? Is this going to be possible to tune with a laptop/ obdII/ something or is it going to need professional help?

A cheaper solution will be to go with a piggyback solution. The Greddy e-Manage is a really good solution. If you want something simple that you can tune without much professional help, you can try an Apex-i Super AFCII. Don't expect miracles out of the SAFC though.

Any other stray sensors/ lines that need to be relocated or anything?

You'll probably find that out during the install.

*Oh, and stick with stock cams.

t3/t4 turbo? Isn't that turbo a lil too big for a 2.4?

Nope. There's guys running them on their 1.6L Civics, etc. Depends how much boost you are going for. Obviously, a bigger turbo is going to have a lot more lag on low boost than with higher boost.

INJECTORS A MUST

and look into an exhaust.

might be best to even get 3" piping all the way back!

but like fusion said he might throw a ride through the block!

BEEN THERE DONE THAT! not fun!

spend a little more money at first and get it done right!

spend no money now, but pay WAY MORE later!!
