LOL...yeah you have ;) I actually would love to see the "good stuff"...and, learn how to properly use a scope!

If the ECU is grey plug, it's an '89+ and should hook up just fine. The '87-'88 ECUs were yellow plug. A new harness is an excellent investment ;) If the ECU is really JDM, you will have to eliminate speed cut....you can do this by buying an HKS speed cut defender or disconnect the SPD...

You'll need to get your hands on an '89 and '92 wiring diagram. Please use proper connectors (like deutsch connectors) to mate the wires. Last I checked, Champion Toyota has a main harness for around $370 ;)

First of all, I didn't make the "delete this post" comment...but, you did for mine in post #24 above. Power is relative...like I said, the EGR does not function above ~4500 RPM, so there is no effect on total HP the engine produces. The EGR was designed to do two things: 1) To lower NoX...

First, this thread belongs in the GE Tech Section since it is a NA-Turbo swap. You need to read this: http://www.supramania.com/forums/showthread.php?t=34560 I'm moving the thread since you will get more accurate help there. So, the new harness has grey plugs...it has to be an '89 since...

Is this a NA to Turbo conversion? The color plugs on the ECU and the harness used need to match. Also, there is a big difference between a turbo and NA ECU. I'm a bit confused as to what exactly you are doing? Please explain in detail and reference the colors on the harness you are using...

What color are the plugs on the harness in your car? On the JDM ECU?

If the head bolts on the motor right now are at factory torque, I'd re-use them in a heartbeat ;) Torque to 70-75 ft/lbs and call it a day. If you get ARP bolts, use the ARP spec...75 ft/lbs on an aluminum head using moly for lube. ARP studs are better...the spec is 85 ft/lbs using moly...

Enough with the insults and name calling...IJ warned both you guys. Tone it down or the staff will "take it to the next level". Start with this thread Derwin: http://www.supramania.com/forums/showthread.php?t=80267 Removing the EGR running a USDM TCCS is a fools mod. Enough about the...

Yes, E85 will help. To take full advantage of E85, might be time to think about a standalone ;)

You tuner is telling you the truth. You need more flow through the head...cams are part of the equation and will net you some gain at that level. To take full advantage of the cams, you will need a port job on the head and oversize valves. The meth injection is so you can keep the motor...

Personal reasons? Mixing oils is not a good idea...the additives can cause "conflicts" in use. I'd like to hear the "personal reasons" you use to justify what you use is better than the petro engineers at Red Line have spent a great deal of time/effort in making MT-90. BTW - Lucas does not...

NAPA Gold filters are made by Wix...that's what I would use if I were you. the Toyota Denso filters are good, but hard to come by. The Toyota Thailand filters are not much better than a Fram. If all else fails, WalMart SuperTech filters (made by Champion Labs) are not bad.

Studs are better...but, if you had bothered to search a bit you would know that ;)

Did you read the filter thread? Based on your question, it doesn't look like it. Actually your oil pressure is not that bad for a 150K stock system...it's within normal values. You want to replace the cooler relief spring. Shimming applies to the oil pump relief valve for higher...

First of all, Fram filters are crap: http://www.supramania.com/forums/showthread.php?t=42763 It's your car, but it will be a cold day in hades before I would run a Fram filter on my car. Get a Wix or a PureOne filter...I order Wix filters at www.rockauto.com or get a NAPA Gold filter (it's...

The small space between the cylinders is going to be the problem.

Since you are new, you need to know the EGR subject has been beat to death. Read this thread (all of it): http://www.supramania.com/forums/showthread.php?t=80267 Cooling the head: - Behind the EGR cooler there's a water jacket in the head. - The reason it's hotter around #6 is it's the...

And that's not going to happen until the motor is back in the car and you can provide useful info...like ECU codes. You seriously need to read this: http://www.supramania.com/forums/showthread.php?t=20163 Enough of this crap...Thread Closed

If you decide to change the cam timing, just be careful. Small increments ;) I'm going to be on my annual pilgrimage for the next few days to experience all the mean and nasty things that can happen in a 747 simulator. Won't have a lot of time to hang here till Wednesday night. Good luck!
