I had IS300 coils running good in wasted spark mode on the AEM V2 and a DH61 igniter. I've just converted to Granatelli Xtreme COP coils powered by an EFI source coil igniter module wired to fire full sequential. Cranking the car over it sounds like it's only firing on one cylinder. All coils...

Approved by Supracentral Hey guys, I just launched a new site I've been working on the side. It's a convenient way to show off your car and host your "build thread" - completely free. The concept is very simple, but I feel it's a better approach than your typical forum for this type of stuff...

I'm putting together an automotive website, and am in need of a couple pics that stock photography sites just couldn't satisfy :p. I'm looking for a couple things: 1) A pic of some serious mechanical carnage (rod through the block, clutch exploded through the bellhousing, etc.) and 2) a pic of...

I got my AEM V2 up and running pretty well and am starting to do some light road tuning. It idles, run and drives pretty well but medium load (~ -6 psig to 0 psig) at low rpms (1500-3000) it stumbles and actually kicks back just a little bit. Higher RPMs are a lot better but it also feels like...

I just installed the AEM V2 from driftmotion and I'm having some trouble getting it started. The car ran on the stock ECU+maft pro the same day just before installing the AEM. Relevant mods are: - GM 3-bar MAP sensor - GM IAT sensor - IS300 coils on the stock igniter - RC 660cc...

First off, my setup is nowhere near stock running on a stock ECU with a Maft Pro. I realize this won't be perfect and isn't optimal, but I know something isn't right. Relevant mods are: * Aeromotive A1000 fuel pump and respective Aeromotive regulator (-10 feed/-8 return) * 680cc injectors...

I just finished rebuilding the 7M. It runs pretty good, and after 50 miles I did a compression test to make sure everything was actually good :). I did it on a fully warmed up engine, and all of the cylinders were within 5 psi of each other although the readings were a little lower than I had...

I just finished building my engine and I'm not getting spark on cylinders 2 and 5. It fires for a second and then the ECU shuts it down because of the code 14 (not getting IGF signal from those cylinders). Here is what I have checked so far: IGF wire good between igniter and ECU (hence I...

I'm referring to the one at the upper left of the crank snout. It appears to not be used, but it also doesn't look like it bottoms out like the rest (there is something else back there). I'm thinking it's just connected to the main stud threads (no clue why), but I want to make sure it isn't an...

I need to replace one of my crankshaft oil galley plugs as it stripped and needs to be drilled out. I ordered some 12x1.25 plugs but they are too small. Toyota apparently does not sell these independent of the crank, so I need to source them elsewhere. Anybody know the thread size of these buggers?

I've measured all of my journal diameters on the crank and have the following: Mains 1 - 2.3624 2 - 2.3623 3 - 2.3621 4 - 2.3621 5 - 2.3623 6 - 2.3621 7 - 2.3621 Rods 1 - 2.0467 2 - 2.0467 3 - 2.0466 4 - 2.0467 5 - 2.0468 6 - 2.0468 Great! All within spec, but I'm...

I'm looking for some polyurethane motor mounts, and haven't had much luck finding ones for 89-92s. BIC only makes them for 86.5-88s. Without getting some custom made, I have found these so far: 1)...

I have my Maft Pro (software version 5.27) set up and running with speed density great except for some slight off-idle hesitation/stumble. I've tried to adjust all of the "tune response" settings but nothing seems to cure it, rather it only seems to get worse. I have a FFIM w/ 80mm throttle body...

I've had my Tial BOV since I bought the car, and it was originally on the upper IC pipe right before the 3000 pipe. I would rarely hear any surge with this setup. Fast forward to now, and I have a new FFIM and just got the Tial mounted on the intercooler pipe right before the throttle body...

I know this may not be the most popular style for MKIII Supras, but in my opinion it looks the best on our cars. I'm looking for pictures of your Supra (or others) with meaty tires that are not stretched. Any Supra with aftermarket wheels and at least a straight sidewall--if not more--qualifies...

I currently have a FFIM, and during the install I just temporarily grounded the ECU wires to the chassis. They are grounded to the back of the intake manifold stock. I have no location on my new one to ground them, except for maybe on one of the studs holding it to the head (I would have to...

I'm looking at some Work Equip wheels in 17x8 +35 and 17x9 +35. These will fit just fine, except I'm worried it won't clear my big brake kit (4 piston kit from Arizona Performance). It would be easy as pie if I could see the wheels in person and just use arz's template to see if they will clear...

I'm getting ready to install my MAFT Pro and Apexi AVC-R boost controller, and I noticed that the AVC-R comes with a "pressure sensor" that is plumbed into the manifold vacuum. The MAFT Pro (in speed density mode) obviously uses the GM MAP sensor to read pressure in the manifold. Is there a way...

So I need to mount my Tial BOV on my intercooler piping: I'm leaving room for an IAT sensor and a meth nozzle in the engine bay before the throttle body, and I don't think I'll be able to fit my BOV there like I had hoped. I'd like to mount it as close to the throttle body as...

I would like to run a meth injection setup in the future, and I am currently converting my car to speed density using a Maft Pro. I'm trying to decide where to place the IAT sensor so I can easily install a meth nozzle later on. I've read many differing opinions on this, but should the IAT...
