I bought a maft pro setup and have a few questions. I have the stock 440cc injectors and I have some 680cc injectors that came with the car. In addition, I have a HKS FCON W/ GCC. Now my question is should I run the 680cc injectors and get a WB O2 sensor and keep the HKS setups or change to...

Well I mean I understand what to expect from the MAFT. It is a support mod. It won't make the car fast by itself but it allows for more precise tuning and converts me from AFM to MAF and from what I read speed density is a lot better way to go for 7M's ...

I just bought MAFT and wondering if I got a good deal. For 160 shipped I got GM 3" MAF sensor, 2x Vibrant 2.5" to 3" couplers and all Vibrant stainless T-bolt clamps, MAF translator, and MAF harness. Did I get a good deal? I'm going back through this car and building it like I want and not...

finally something I can be useful with on this site ... I'm a salesman at a welding supply store and the smallest tig machine that can aluminum with Lincoln is an Invertec V205-T AC/DC ... I can get it for 2845.57 ... Unless you were looking to do this as side work it's best to find a shipyard...

Finally all ready to perform my boost leak test tomorrow [yay me get to work on the supra while everyone else is at parades due to it being Mardi Gras down here] ... I will be replacing all vacuum hoses as well but I got to thinking about something and need some info or feedback. The car is...

Honestly I never thought about using a smoke machine. I will definitely go that route with it. The coil packs and spark plugs and wires were good. I still don't think it's a vacuum leak even though I will replace every hose. But once it warms up a bit it has excellent throttle response and...

I have composed a check list of things to check within the next couple days check coil packs check spark plugs and wires check intercooler piping check all vacuum lines run a compression check just for good measure check timing with timing light Is there anything else anyone can...

that's exactly what I was talking about ... So I will just plug it off. I will drive the car up on the ramps today and start checking the intercooler piping and see if I can get to the wastegate since its a external dump style wastegate. Any particular way you suggest checking the wastegate...

I appreciate the modified diagram greatly. I will definitely have to look into this. However what I thought was a VSV isn't I guess then. The item that I know isn't hooked up is the one that goes to a filter and it where the throttle stop is located. It seems like a diaphram of some sort.

Well the only VSV I really noticed was the one near the firewall and the previous owner blocked off the EGR [I am in the process of trying to get the engine all back stock for the most part as far as EGR and boost sensors etc ...] I will check the other VSV. The other VSV is located above the...

I will put a timing light on it tonight just to be on the safe side. As far as the idling I noticed that my VSV is not hooked up. I was looking on the side of the throttle body and noticed that there was no vacuum line running off the bottom of it. Will this effect idle? As far as it running...

When I fixed the TPS I really didn't notice a change in performance and even after fixing the coolant temperature sensor either. The only thing is that the temperature sensor fix made the engine a bit easier to crank. But if I sit there for a few minutes while the car gets to operating...

Okay let me start with saying that I have no check engine lights. I had a code 22, 51, and 34. I bought a new TPS and calibrated it. I replaced the coolant temperature sensor. All of my codes are gone now. My next question is concerning the code 34. Can you still have a boost leak and no check...

Is the brown wire supposed to be running off of another wire? [see pictures] Something doesn't seem right. And I have a yellow/black wire that has nothing attached to it. http://www.supramania.com/forums/album.php?albumid=382&pictureid=2618...

After that code is cleared it should run very well. What can I expect? I have no idea what a 7MGTE runs with no problems. I bought the car pretty much as is and just had to tie up a few loose ends. I think the wastegate is set at either 8 or 10psi. I just got it up to 5 to make sure the BOV...

Trust me I believe you ... I just wanted to confirm it because I had multiple people trying to tell me otherwise. I will take your word over pretty much anyone when it comes to a situation like that, but I appreciate the confirmatin.

I know the sensor itself is good considering I just took it out of the box. I will check the voltage and do a resistance test when I get off of work. However, I'm a bit confused on one thing. Does the coolant temerature sensor effect the performance of the car? I definitely want to clear the...

I have installed the new coolant temperature sesnor ... The plug coming off the harness had been cut so I used a plug off a 7MGE. I connected the green wire and brown wire to the sensor. Are those even the right wires? Those are the only two that I see no connected unless I am missing something...

Ahhhh finally some progress ... I finally cleared the Code 51 and next is swapping out the coolant sensor since I have found where the wires were cut. *prays* Hopefully this will fix my problems and I don't have to track down any possible vacuum leaks. As always thank everyone for any...

Okay I have set the TPS as stated. I turned it until my ohm meter went from "OL" to a small reading ... Now what? I check the codes and I still get a Code 51 Also ... I wasn't able to find a .700MM feeler gauge so I used a .711MM feeler gauge. Will that hurt the calibration?
