How about this turbo kit on my vibe?

[Faultline]

I sppoke again to a turbo guy that I talked to in november,but lost track of in November,because he moved. But I found him again and here is what he will do for $3100.00custom manifoldt3 turbo w/ external wastgate adjustablefront mounted intercoolerand now for the tricky part, we are sucking the air thru the MAS , like stock, with just a k&n filter, and adding a recirculating Blow Off Valve to keep the air calibration correct. ther will be a return fuel line...so we can use a vortech FMU (fuel management unit) to have proper fuel air ratios. ther will be a higher pressure fuel pressure regulator , but still stock injectors. Were looking to do 6psi boost. no piggy back or stand alone ECU. and no gauges.MY questions : can the ECU still lean out the fuel , with the FMU installed?Will the Ecu retard the timming at all under boost? or under this low of boost , will I be in danger of detonation as vvt-i advances timing at the high end?IN the tuning phase, He will put on his panel of gauges to moniter things, we can add a timing retarding unit if needed , and bigger injectors if needed , and guages if I like, but that will be extra. He said that stock injectors with a bigger FPR can flow more fuel than if a piggy system is tellin them too. And talking to Spyder guys with the PE kit,Wich only replaces the stock FPR, said that they were fine until they wanted more than 8psi boost. we will see.what do think? please criticize and offer any concerns Thanks good Vibes faultlIne

what engine??? 1zz or 2zz?? is it a GT... lemme know and I wil answer your question

[Faultline]

Oh yeah , I have the 1zz, manual 5 speed. But oops I just went down this morning and put down 1/2 the $ to get things rolling , He is going to order the stuff he needs, and when it all comes in in a week or 2, I will go down to his shopp and he will take off the manifold to make a jig then replace it so that I can drive around in my car, while he fabs the manifold and puts together the intercooler stuff, so that when I come back, it will take him about a day and half to put it in the car. The manifold is steel...but very very thick..nearly 1/4 inch. He said that its cheaper than stainless , but because of the thickness he has had very good luck with it not ever cracking--only one car that was for racing ,and it was pushing some serious speed. He showed me one and and it was very beefy and was real clean work too.He said that he has had stainless crack too. He showed me some pics of som installs,that struck me as being very neat and clean work.The core for his intercooler .installs, is 9"x19". so much for my own IC which is 6"x14", dont worry about my post on how to clean it caus i do not need it any more Any how, 9"x19" is huge! He said he likes his air coool!So basically, the fuel management is being run mechanically at this point.FPR and FMU and return fuel line.Ther is a trick here though with the return fuel line that makes life simpler,But I do not know what to expect when it comes to the tuning phase. The vibe ecu is diferrent, can it stil make things lean with a mechanical FMU? Can a higher pressure reregulator push enough fuel thru stock injectors? So far, the kit would seem reasonable $ without adding any piggy back electronics, So I already have my I on Split Seconds FTC-1 unit , or a J&S unit , But I hope I do not have to.and wont cry if I do ...so what do you think?Good vibes Faultline

IO would try the split sec unit before I went with a FMU.... the FMU is just gonna be problems... you will run REALLY rich under boost.... I drove a celica with that set-up on it.

[Faultline]

thanks for the reply andrew Are we to asume that the celica's FMU was set at the same fuel/air ratio? I am a little cloudy here. I thought that under boost that you could set it at like 12:1 ratio but you could set it leaner or richer than that?And I am a littlle baffled about how they adjust according to fuel pressure rather than having a sensor to the MAS.Also, I think that one of the ideas here is to get more from the injectors when set up this way.The thing to find out about using the split second FTC-1 is whether the cam sensor, crank sensor, and MAS is the same as the celicas on the Vibe and or Matrixes. Also , what do you think about a steel exhaust manifold whose thickness is 200 /1000ths , I believe he said ?good vibesfaultline

OH YEAH.... all the FMU does is raise fuel pressure and force more fuel through your injectors.... what you need to be able to do is control the injector pulse(how fast it cycles) even on our 500 hp cars we run about 40-50 psi fuel pressure. The FMU works.... but not great or consistant

Thanks again Andrew, I did talk to Mark at split second a couple of weeks ago, and actually , he is the one who posed the questions about the sensors LOL. Fortunately for me , I only live a couple hours away frm them, they recomended that I get a service manual for the Vibe which would help them determine the sensor issue. They are not to keen , though ,on doing installs. Except for speciall projects. But any how, I just need to find out if the ftc-1 will work with the vibe ecu. the vibe ecu , to me is the stealth factor in this project, for all I know , it is the same as a matrix , or celica; but maybe not. I am wondering, what piggy back the sc will be using to go with our ecu?. Oh yeah... I realiz that the injector pulse remains the same with a fmu...just higher pressure... so if injectors fail under these conditions, do they just dump fuel into the system crazy like? or maybe too lean like? or like ...oops there goes the motor like? I guess in the end , once I am boosting, I want to learn how to read the signs of aproaching detonation , or at least not be so fearful of it. I think I will ad a pyrometer and an A/F meter, What meters or guages do you put in your boosted cars for safety?

[andrewmva]

I think I will ad a pyrometer and an A/F meter scrap the A/f gauge.... it will do you no good... the delay is Toooooo long by the time it read lean.... your done. I would go with FP or an OP gauge instead... and a boost gauge for sure!!! If the injectors failed from too much pressure they would probly lock... letting NO fuel in (not good) Wish I could help ya more with the sensor issue... -but I honestly don't know.... you have a GT right??? there should be an ecu code on the outside of the unit... gimme that # and I can check out my ECU (Matrix XRS) and see if they are the same

[Faultline]

no my car the base , with the 1zz. But I have not had time to get the ecu #'s . Its dark whenI get home, what a wimp, ..I know. but maybee this week end. but since you have the xrs, does its ecu match the celica gt-s? BTW Andrew, I stumbbled on some old threads on Spyder chat ,from like the summer of 2001, anouncing a turbo kit for the 1zz in the spyder from MVA racing. The Kit was to be in 3 stages starting at $3999.00. Marcos comes on in the middle of the forum and says that you could use stock injectors up to 11psi on the 1zz- which upsets everyone , but gets everyone talking about rising rate fuel regulators , and using higher fuel pressure to get more from them. This is all before Kaz's car. so.... did yu guys ever market the kit, and what about marcos say up to 11psi on stock injectors?????

[andrewmva]

that was with stand alone management though... very different from a rising rate reg. XRS and GTS should be the same but I'm not sure yetNo turbo kit... however we will do custom installs on-hand.making a kit that is not perfect is a good way to ruin your name(turbo performance) I don't wanna do that. we have that MR2 here now and have done pistons, rods, the head everything I will keep everyone posted on the progress.quote:no my car the base , with the 1zz.
