Specs on the rebuilt motor.
Pistons, rods, bearings, rings
And i'm mad at you for going s/c to turbo, but I love your beast of a car anyways.
oh and btw...talk about alot of room to work there between the radiator and intercooler NICE!

motor is stock pistons rods and rings........
I hope to do the same someday.

was the reason you pull the maf before the turbo due to space or performance
I can't remember but I think putting the maf there cause some stalling issues, for some reason I can not remember the pros/cons of placing the maf on onbe side rather than the other
I've been drinking so give me time and I'll remember if someone does not post the answer

Well for one if you vent your bov to atmosphere you will have a stall on decel seeing you are bleeding off metered air. Its somewhat harder to tune pre turbo but not im possible at all. I always will put my maf charged side just to make my life a lil easier to tune. Hell i may even go mafless this year to be honest.

I do agree with tuning being a ***** with the maf on that side tho but I'm still using the FMU so I'm keeping my fingers crossed.

ok thats what it was tuning with the maf pre-turbo, so how does the car control the injectors if it does not see the extra air coming from the turbo. I know you have a fmu but that work off of vac/boost and the safc but maf voltage. I am not sure about a safc but on my vafc2 you could tune into close loop but the ecu would override so I set my everything to kick in after 30% throttle and 3k rpms which is fine but what are you going to do when your not in those ranges for tuning
I am asking cause this quesion came up before, when I was worried about being on the highway in 4 or 5gear around 50-70mph and floor it

The maf on the inlet side of the turbo sees all the air that is going into the engine because it has to come through the maf first. Pretty much the ecu is going to try to keep the car at 14.7 afr in closed loop, so adjustments you make the ecu will try to adjust the afr to keep it 14.7. Alot of turbo people just tune the open loop and the transition range into boost. Right now my timing is slightly advanced in closed loop and retarded in boost. Injector pulsewidth is increased in the transition ranges into boost with the emanage blue but I'm going to experiment with an o2 clamp and see what the results are. For turbos you will make more power safer with something like an emanage blue/ultimate versus safc/vafc because you have timing control and can increase injector pulsewidth.

sweet build man, 2 things, someone told me i couldnt use FMU with a turbo 'cause the power was so sudden and the FMU is not quick enough to keep up with the fuel demands of the turbo, and also i thought the MAF had to be on the charge side. man when i get this new job, imma go turbo, Kzoosh gonna help me right? :-)

Im always down to help the peeps out. U dont have to put the maf on the charged side. Bish you will have a stall issue trust me. U may not have it now but you will. I think the vafc has a anti stall feature built in. Once you do have the stall you can set the anti stall to give it a little more gas per say to keep from dying.
but then I sold it before I got it right

I do have an issue where the car wont rev past 2600 if I start it up once. When it does that I just shut it off and restart it and it works fine. Any suggestions?
It was, I used a forza/obx 3in inlet muffler. It sounds good, a little raspy in the begining but once it warms up the tone gets better ant the rasp goes away.

Turbo is way better than the supercharger.

Although having it on the charge side is nothing bad, MAF's do die occasionally, and most likely not related to it being on a turbo car. See if you can swap with someone else and test it for a bit.

Thats one of the symptoms for the maf giving problems, what maf is it?

Nice, I think Im ready to look into a 3" setup soon. I was worried about it being too loud but the car isnt my daily anymore so it shouldnt matter now.
