it pulled very hard. i only held it for a like 2 or 3 seconds then let off. how is 30psi not safe? just curious. people run 20-25 all the time

so earlier i was having boosting problems where my car wouldnt boost any higher than 16psi even with the MBC all the way up. it didn't hit fuel cut, it just wouldnt boost higher. so someone told me the waste gate flapper was probably opening on its own and needed to be tighter, so i shimmed the...

well my car doesnt have a cat. lol its a completely open 3in exhaust... and no, it hits 16 psi VERY fast

oh, ok.. i will try that... i'v always wondered if it were possible for the flapper to open like that on its own. i'll give it a shot tomorow morning and see what happens. thanks IJ.

what does preload it mean?

i had a cheap manual boost controller and with it tighted all the way it would only boost to 16psi, so i got a new turbonetics type MBC and the car still only boosts to 16psi even with it all the way tightened.. so i disconnected the MBC and just plugged up the boost line so it should be...

i REALLY think we need to have a GOOD video made for the MKIII's

i think the best part of the video is the fact that the supra sounds so beasty it makes the staticy sound on the guys video recorder IN Lambo!!! lol... truly AMAZING

that just pisses me off.. that supra doesn't look like it was in that bad of shape till he shoved it in the ground!!

also at family video there is a video game and on the cover is a supra with the hood off, the turbo is on the drivers side.....

well ya, but just the idea of not having to stop and pop the hood everywhere.. makes things alot easier.. im just iffy about how this MBC works though.. :S

im looking for a new MBC and i saw that this one was an adjustable from in the car.. which would be alot easier.. but im not sure how well it works, or even how it really works,, could someone shed me some light on this? i would really appreciate it! thanks...

ok then look at this video... approx. 54 seconds into it.. all pictures are of supras.. this guy is messing with the TB on the passanger side of the motor... http://www.youtube.com/watch?v=EwGJqW0Ezw4&feature=related

what are SR's and RB's?

is there a any model MKIV that has the turbo on the right hand side of the motor instead of the left hand side... when looking head on at the car?

what exactly is the maft pro?? i'v always wondered,, and how does it work?

please add me to the list!! Suprafanatic -- Toyota Supra--MKIII Turbo--- 60-1CT--Spearco IC--550s/lex--other mods

come on guys..there is no reason to start bashing people here... but the problem could be as simple as a vacuum line not being hooked up. alot of them are important.... explain your cars condition alittle better, what exactly are you working on, and what isn't hooked up at the moment?

you have a bad FPR or hooked it up wrong.. weather or not you have the 12v mod the fuel pressure should go up SOME when you adjust it..IMO

no i didn't do that 12v mod.. why is that so important?
