Do I need to upgrade trans, etc.

 

A clutch will be about all you need other than a better flowing exhaust.

 

I second that.

 

-1 step colder plugs from NGK would be a good idea too..

 

I've been reading as many posts as I can on the S/C. I've been thinking about getting the Greddy. Correct me if I'm wrong cuz I don't know much about F/I.

Do you need a aftermarket intake? it doesn't come with anything like that in the kit, right?
Obviously you want hi-flow headers, cat, cat-back.
Stock fuel injectors can cope fine with the S/C?
The stock drivetrain can handle 129 whp, if need be?

 

I think you would want to put an after market intake on, better airflow to the SC. The stock box can be very restrictive to air. The kits dont come with intakes, would be nice but thou.

As you stated a high flow exhaust is good, will help get the exhaust gases out as fast as the SC is pushing it in. Thou alot of people are just running new headers and axlebacks with the SC.

I agree the stock fuel injectors would be fine, but why not upgrade if you got the money and want to do a little more work(fuel pump, fuel presure regulator, fuel rail).

As for the drivetrain, i dont think any of us really know what this drivetrain will handle over the long hall, only time will tell. But i would think it could handle 129hp no problem. sorry wasn't sure if you were asking questions or stating what you know, but i chimed in a little.

 

Supercharger + I/H/E + clutch


Later--> 330 RC's, pump, dyno tuning




I still prefer something intercooled, eaton roots type s/c's blow a littler hotter air than i'm comfortable with

 

Don't forget that with any kind of air intake charging system cylinder intake pressure increases. Unfortunately the chance for detonation increases also. Along with a colder spark plug, it is recommended that you also switch to a higher octane fuel ( 91 +) for more efficient cylinder cooling and combustion. The third trick you might consider is changing out your 180 thermostat to a 160 unit. Personally, I would also install a thermostatically controlled engine oil cooler along with a few gauges (boost, oil pres, oil temp, water temp) just to keep an eye on things, and switch my fluids over to synthetics.
Good luck!

 

Later i'd recommend an oil catch can as well to filter out the gunk that may build in your lines. I don't have any s/c experience but i have about 2 years of personal turbo experience on my previous vehicle (02 civic) and within a few short months after installing the turbo kit, gunk blocked my PCV valve. Watch for blow by and all that jazz

 

NGK coopers or Denso Iridiums

 

what about torque master plugs think they will be fine ?

 

Now that you mentioned PCV valves, I would like to bring up a very important point. Your normal, everyday PCV valve is designed to operate in an engine that always has negative or zero intake manifold pressure. In effect, your crankcase is always venting in one direction with a normally aspirated engine. The reason your PCV valve got ____ed up after you installed the turbo is that now, with positive manifold pressure, your crankcase ventilation system is attempting to work in reverse. Think about that for a second. A properly operating PCV system normally releases positive crankcase pressure to the negative pressure intake which sucks (vacuum) the vapors from the crank. When you have a boosted manifold, positive pressure wants to reverse the flow of gasses and oily vapors from the intake back down into the crankcase which is already under pressure! One way to eliminate this dilemma, would be to vent the crank to atmosphere...but as we all know...that is illegal.

I have owned several factory supercharged and turbocharged engines in the past and these engines are always equipped with a PCV valve that allows pressure to bleed back and effectively travel both ways. These engines do not build up sludge in the PCV system. On the other hand, I boosted a 3.0 Solara engine with a TRD sc kit a couple of years ago, and had some sludge build-up. I am sure there are a lot of people out there that know a lot more about this phenomenon than I do, so maybe someone can chime in and offer a little more info on how to get these PCV systems to run cleaner on these aftermarket supercharged and turbo boosted engines.

 

yeah that exactly what i did to my xb with Greddy S/C and it been working good sinc Jan. 06

 

With any other type of FI mod, I would get the car dynoed to check AFR, unless you have your own wide band. The Greddy Emanage was cool and all and the car felt good but I was still curious as to what the mapped the afr at. After dynoing the car I realize its too lean.

so have you done anything to correct the problem of being to lean.

 

I have the greddy and not one problem yet.. make sure you have an 05 and lower XB before you buy it.. it dont work in the 06 becuse the ECU is differant.

Other that the clutch sucks on the 5spd.. if oyu have an outo i would add an transcooler.

Intake Headers Axel back.. thats what i would recomend..

 

The clutch is fine. I would recomend you getting your car dynoed or have your AFR datalogged so you know exactly what the Emanage is doing. At 13.5, it really is too lean for a turbocharged car. Intake is fine as there is a tube in the stock box that can simply be removed. As far as headers go, there is no need to waste money on headers if someone is going to turbo as the ex manifold will be changed anyways. IMO, the axleback is pointless because you are essentially only upgrading the muffler. Most people slap on an aftermarket exhaust and get whatever gains the part makes without choice. I will be trying different configurations to balance the hp and tq curves.

I was tuning the Emanage on Friday and the car feels a little better now. I will proably stap it back on the dyno on Tues and do some more tuning.

 

i am interested in buying a supercharger but i wanted to know if it works on an automatic xb???

 

The Greddy SC is built and made for an Auto... Just not an 06. Supposidly there is a fix for it.
