    new B6t owner..

    Did a bit of poking around on here. Still got lots to learn on this little motor. But also got a few questions. I couldn't quite find yet.

    Like what's the stock turbo good for?
    What's a decent upgrade for the turbo?
    What kinda hp can these motors handle?
    What options do I have for ecu upgrades?(I've noticed some members offer chips?) Any other small things you guys recomend upgrading while I have the motor out?

    I was planning on just doing timing belt headgasket and some head studs.

    You might be better to send it to the BF GTX email group:
    323gtx@yahoogroups.com.

    The ECU upgrade would be getting it chipped (or buying a chipped ECU - Corksport sells them). Buying an FCON (a piggyback 'ECU') is another way. Both allow about 16 psi boost vs. stock about 10psi. About 180hp.

      Well I would like to see around 225-250hp. Upgrading stuff isn't a problem. Just read the vj-11 thread not sure what that will do me to for hp. Will have to do some more poking around on this one. Heard the T28 mentioned a few times. What's the pros and cons to each one?

            -stock turbo is good up to about 14-15 lbs boost or about 170-200 hp depending on other things
            -there r a few swaps that u can do but for big power i would have someone make u a manifold witha t3 outlet flange
            -there is a member here on CP, rocketman, he has a nice chipped ECU, corksport also sells one
            -a free flowing intake/exhaust, chipped ecu, boost controler will get u close to 200hp


            the swap u are doing is awsome in theory and is very possible, but 1 quick little warning... i have a friend who spent a year converting his festy over to a B6T big turbo monster, he had it all gutted down to cutting out the door inners and running a lawnmower battery. That car was scary fast, and when i say scary i mean like it just felt unsafe like u were on limited time and gonna die. He actuly felt the same way and parted it out. The car was EXACTLY what he wanted but once he had it he realized what he really built...a lighwieght korean tin can with a super fast Mazda engine. If thats what u want u are looking for help in the right place but i suggest a roll cage to strengthen up the body of your car and a LSD diff to help with the tourque steer u are gonna get.

            good luck

                well the car already has the aspire brakes and what not needed for it. gonna try and figure out a cage with one of my buddy's. wanted to hit up some autocross this year with it. and the cage was already in the plans but not sure how much of a cage I wanna go with. as for a new manifold for the T3 what kinda turbo are you recomending? I have some talented friends when it comes to welding and fabricating. I also plan on using this as a everyday car. so i figured 225-250 would be reasonable and still driveable on the street.

                  lol, 225-250 in a festiva is reasonable...I don't know if I'm with you on that :p but it sounds like an awesome project nonetheless. Hope it all goes well.

                    150hp is reasonable, 250 will be very fast. Remember u are putting this in a car that wieghts around 1500 lbs.

                    Small t3 or a gt25 or some dsm turbos like a 14g/16g will be fine for that power

                      This isn't my first car I'm building. Just my first time with the b6t. I've driven cam waugh's original fastiva as well my srt-4 is in the 11's. But the look on peoples faces when you walk them in a festiva is priceless. But the b6t is all new water to me.

                        So if you chip the ecu and put a vj-11 on it how come you can only boost to 16psi?

                          VJ11 ain't that big flowing a turbo, kinda like the vj20, anything beyond 15 is hot air. Getting 250whp out of a b6T is a neat trick and would involve a lot more than a chip and bigger turbo, you'd be looking at a standalone and custom plumbing and big injectors and etc etc. 200 is more realistic.
                          A T3, at least the size T3 I'm used to, on that little engine is ridiculous. Lag lag lag. GT25=good idea if you're bent on getting rid of the vj14. Ballbearing FTW. Also, throw away the stock "intercooler" and get a decent frontmount. Once you get the thing running, get ready for the car to make its own decisions as to when to change lanes...
                          '90 AWD Protege, full GTR drivetrain swap, ~320 whp daily driver, RIP, and
                          '90 AWD Protege, yet another GTR swap, Open class rallycar with a Toyota GT4 gearbox swap, thus crossing the line between hobby and mental illness. And a Brabus E55 K8, removing all doubt.

                            well 200hp how do you guys recomend getting there? vj-11 and some injectors and a chipped ecu?

                            so far it's gonna have a front mount and some sort of chip for sure. and I'm sure my buddy has a vj-11 laying around from a few cars he's stripped.
