greddy turbo kit
#2
an intercooler is always recommended in any boosted car. no matter what psi you will always see a gain in horsepower. i guess its truly not needed but i dont see a point in not having one.

You do not need the intercooler. The kit out of the box is ready to go, 5psi wastegate. If you plan to tune for more power in the future an intercooler is a good idea. Greddy makes a bolt on intercooler kit to go along with that turbo kit designed for the xB.

John, thought you were going w/ nitrous.
3min3m2, this is the greddy turbo for the 1NZ-FE xA / xB, not the tC kit. The base Greddy turbo doesn't come with an intercooler or upgraded injectors, and it does not even include a new intake, bolting instead to the stock airbox. No spark plugs either. The internal wastegate is set at 5 psi.

The intercooler and intake are extra, found here. The intercooler kit says it needs the Airinx intake to work, not sure if other short ram intakes will work as well.

They recommend going with colder spark plugs, the standard NGK V-power one-step colder work fine and are about $8 for the set. Also, upgrading to tC injectors is a good idea as the supplied base map runs lean, and of course get it tuned before agressive driving.

Heh, no problem, figured that was the case. Not sure why they decided to slim down the kit for the xB, maybe because they felt the motor was only good to 150, so with holding the boost @ 5 psi the I/C just wasn't needed, less cost and lower weight. I think they should have at least thrown in a set of plugs and bigger injectors, they're somewhat essential.

Sorry dane, mine sold a week ago. If you're on ClubxB, I got a PM from XTNSIV asking a few questions about what I did for my sale, he's getting ready to sell his, send him a message and see what he's thinking.

That's an interesting question. Configured with the Greddy kit, the turbo is oil fed / oil cooled. However, the turbo itself does have a water jacket, there's two other holes on the side facing away from the engine and two freeze plugs on the side facing the engine. That specific turbine, model TF034, is watercooled on some overseas Mitsubishis. However, on the Greddy manifold it sits above the water line for the engine, so it won't cool the turbo when the engine is shut off and a turbo timer is still needed, or letting it idle for a few minutes.
In this picture, the water inlet and outlet are facing up, with the oil inlet on top and the drain on bottom.
here are the freeze plugs, oil feed is facing bottom, return is facing top.

my only concern with forced induction is reliability on long trips, i drive to see my mom about once to twice a year (400 miles) i know i have asked the question before but you seem to be the turbo guru, what is your opinion of how it would hold up on a long trip like that?

my kit seems to be doing fine after a 1600 mile trip. Biggest Issue I had was since I haven't finished my tune entirely, its still extremely rich at one point that my car hits under any acceleration in overdrive at ~72+...so my AFR's would tank to 10's whenever i was slightly accelerating just cause it switched to open loop.
Even with that issue, car still got decent mileage, think 27 was my best tank...
SO the tune is really where it matters. And since your traveling, just take it slow and don't boost a lot and your car will never know the difference...

Long trips should be no problem. Most of that would be highway at a steady speed, i.e. out of boost, so the engine wouldn't perform any different as non-turbo. What really kills a turbo is short trips becuase it needs time to warm up, a cold turbo means cold oil and very high oil pressure, which coupled with quick acceleration from lights means the oil seals can blow.
The only thing is that at the end of a long drive, let the engine idle for about 5 minutes after parking to cool the turbo back down. I always ran with a turbo timer so I didn't have to manually keep track, and a timer never forgets. The Greddy full-auto timer worked well for me.
The water jacket really just replaces the need for the turbo timer. If the turbo is mounted below the water line of the engine, when the car is shut off the water in the turbo housing evaporates and drains, pulling fresh water in to cool the turbo down. it doesn't help all that much while the engine is running. With the Greddy manifold though, this won't work.

you guys have helped me out more than you probably realize, any doubts that i probably had in the past are starting to go away. I am gonna keep you on speed dial Brian in case i have any other questions/concerns. I wont have the money til probably around this summer so I will use these few months to really learn the kit and not just bolt it on like its a CAI or a set of HID's
