how can i up boost on my 18g kit....right now iam at 7psi stock spring for the wastegate.......how can i up boost.......will a cheap ebay boost controller work with this wastedgate or get a greddy boost controller

blaze the chemi

you can up boost with a easy boost controller (manual boost controller). Just make sure you have the fuel/timing management (i.e. TUNE!) to maintain your boost without grenading your pistons and ringlands.

Or if you wanna be really cheap you can tweak the wastegate actuator(sp) arm but i wouldnt suggest doing this if you havent had expierence with it.

The turboxs MBC is your cheapest bet. A lot of the Greddy kits that I have tuned will spike and not hold constant boost using this boost controller though.

urbansi

mine held fine even with it unported and a 3in discharge'd downpipe.

you have a greddy turbo kit too.....is that kit good.......cuz iam pushing 208 to the wheels on my.....how about yours.........am at 7psi.......is that normal.....and how did you hook up your bc..........cuz i try two on ebay and they dont work.......still maxing out the wastegate......any idea.........

get an mbc or ebc, Ebc would be better since you can adjust the boost setting anytime in the car or while driving. But before upping your psi, make sure your fuel system is up to par with the amount of boost you plan on running. Also depends how much you want to boost. For example you want to run 12-15psi, make sure you have supporting fuel pump, injectors, upgraded fpr, and most importantly tuning the car with a standalone ems along with the boost controller. Doing this will keep your car reliable, have longevity and even drive like stock. You don't want to boost more then what your ecu is set at, you'll damage your motor and the turbo. Also you may run into leaning out problems or fuel starvation.

i just tune my car with crome and run at 7 psi whick is stock for greddy turbo......and they guy told me i cant us a boost controller on this turbo .......so iam just check up see if its true.......and all that with only 208 to the wheels is nothing i want more power........stock everything except for 550 rc injector was put in there.....................you know anypleace who sell upgrade downpipe for this turbo and still keep you ac.........

are u running a full 3" setup? you should be able to put a boost controller, especially if your using a standalone system, since you have full adjustability and control over your ecu. Since you plan for more power, save up for an upgraded fuel pump and upgraded fpr your going to need it for sure. You might have to get a custom 3" DP, are you running an fmic as well? with more boost calls for a more efficient intercooler.

yah i have a fmic and stock exhaust the the greddy downpipe.......i was hopping if anyone know where i can get a upgrade downpipe pf 3inc or sothing............

urbansi

i know that kteller used to do a 2.5in upgrade but i am not sure if they still do, i had mine custom made from a local guy using an ATP discharge.

avotegra

what kind or type of exhaust flang does a 18g greddy turbo use.........or bolt pattern..........

VspecSiR

contact spoolin performance, I had them make me a custom downpipe for the 18g. it'll make a big difference

avotegra

how many whp did you get out of that......and how much it cost you........
