We still need to know that it was a 2GNT orginally. The turbo 2Gs are totally different as far engine, ignition, spark plug type, coil type, ECU, etc than a turboed 2GNT.
True. sorry I didnt mention that earlier!

So, it runs that same with the stock ignition stuff on it as it does with the MSD stuff? Are you sure some plug wires aren't going to the wrong cylinders?

Yep runs the same. I think MSD is about the same as stock though anyways isnt it? Ill check the plug wires though! I dont think I could wire them wrong though! I mean isnt it pretty straight forward, or is there something I should know?

It sounds like an ignition problem, or the MAP sensor is getting a bad reading, or maybe you blew up the motor. With the engine running, try pulling out each plug wire 1 cylinder at a time to see if there is no change in the way it runs with any of the cylinders.

I dont think the engine took a crap on me (knock on wood), cuz everything is forged. How could I check the MAP sensor? I will also try the pulling off the plug wire also. If that is the case with the whole plug wire pulling off thing.. how do I fix it?

If you have the car running and you pull a plug wire out, the way the car runs should change. If it doesn't change and the wire is sparking to the engine, then you know you have spark and maybe it is a problem withfuel on cyclinder or it has no compression. If if doesn't change and wire isn't trying to send spark anywhere, then you know it's an ignition problem.

Forged internals don't make a motor bullet proof or indestructable. Their purpose is to handle more power, they will fail also from detonation, pre-ignition, overheating, etc. They will withstand more beating than stock stuff, but it is still easy to blow up a built engine.

Alright after doing the plug wire test, All wires were giving off spark, but 2 of them, the 2 coming from the right tower side, are not sparking as much as the others were, so yeah. As for gas on cylinder, how would i go about diagnosing and fixing it? Does anyone recommend i take it to a mechanic/shop?

Ok, so try replacing whatever powers those wires, whether its the MSD box, factory coil, etc.

I think I may have a timing problem on my hand. Could timing really be thrown off by driving it hard for a night like i did? Looks like the time has come to FINALLY get her tuned. I am like almost 100% sure its timing, because I have done everything ignition wise, and I dont think it would be bad compression. So I have narrowed it down to timing. I will be coming to a shop near you, soon.

I would make sure it is in top running order before you bring it in somewhere to get tuned. If you need to schedule some shop time to get it running right then do it, but dont schedule tuning time if it is running the way it is.

Depends what youmean by timing. There is having the timing belt lined up correctly, there is ignition timing, there is cam timing, there is setting your base timing with a CAS or distributor, etc which are all different.

Well, I havent done much with the car as of late, so i decided to drive it to autozone to get checked for codes because I wasnt sure if the CEL was even supposed to be on (CEL burnt out). They scanned it, and it came back with 5 codes, 1 for the EGR, and the other 4 for each cylinder. I wish I wouldve written down the exact codes, but all I remember is it was something about the exhaust gas recirculation and that something was happening in turn, to all four cylinders.


I drove it home, parked it in the driveway. Went back about 3 or 4 hours later, car wont start. It cranks and will have that noise like its about to compress or something, but once it is JUST about to start, it just doesnt and continues to keep cranking over.

Anyone think that it is my MAP sensor thats f-ed? If so, should I just go 3.5 bar? cuz I cant even find the damn EGR in my car. I have 2 eclipses, and the other one is also 420a (but NOT turboed) and I can see the EGR valve fine, on the passenger side of the engine. God. someone please PLEASE help me


Edit: Alright now the car wont even crank over. It just sits there and does nothing, no cranking at all. I had my dad push me and try to pop start the car, and thats when it started to not even crank anymore. before we tried pop starting it, it cranked, but wouldnt start. now it just does nothing. Anyone have any ideas, or that could come out here and help me... Ill buy you a case or somethin! I would go to a shop, but cant drive! :angryfire:

If your Egr is stuck open at idle then that would explain your crappy idle. Egr is used at cruise speeds like on the highway mostly. When the engine is cold it richens up the Afr allot, so theoretically if the egr is stuck open wide and your engine is cold it will let allot of exhaust back into the cylinders which will displace oxygen and cause the rich fuel mixture to not ignight.

Try swapping the egr's from car to car.
