I cant believe no one said your head might be fucked. If you over heated your engine you probably had grinded one of your pistons against the wall of its chamber. Therefore oil leaks through and your smokin blue all the way down the street. LOL That of course is the worst case situation. I am going through that right now and I am boreing out my block as we speak. Ohh well, you play hard you pay hard, borein my shit out just adds more hp when I'm done. See you on the streets!! Also if you are going in the shop. You might want to get rid of your balance shafts in your block. It limits the 4G63, the kit to replace them is around 50 bucks. Later

 

50 bucks my ass, 50 cent for a freeze plug, a couple dollars for some JB weld, and an angle grinder will do the job nicely

 

nobody said what you just said because it was retarded. he has a blown turbo, the head is fine, and balance shafts don't limit power at all

 

it does in the G54B... but i guess that's what we get for havin truck motors in the StarQuests...

 

lol after everyone says its a blown turbo, then he starts listening, but disagreed with me haha oh well.

 

I am going to say turbo or the valve seeds.Change your oil and see if there is any coolant mixed with it.How many miles do you have on your car?I hope you got some money saved up.

 

how does a balance shaft limit power? i just don't see how it's phiysically possible? it's like 1/2 lbs rotating mass so yeah i guess it robs .1 hp from you but i don't see how it could be a limit in any way

 

well in the G54B the balance shafts are driven by the timing chain. of course the timing chain is driven by the crank. also, they are a main failing point in the G54B (which i believe is why i spun a rod bearing). eliminating them in my car nets about 5hp, increased oil capacity, and slightly increased oil pressure. only draw back is that you should get the bottom end balanced if you plan on revving above 6k (which i prolly won't, so it doesn't really bother me) and a slight buzz from the shifter.

 

that still doesn't make it a limit.. all it is is extra moving parts.. you gain power because you are removing rotating mass... 5hp seems a little on the high side IMO though

 

it's alot more reasonable than the 10-15hp claims that run around on StarQuest boards. lol. i dunno, but i guess it was a shitty design on the G54B. they're more a failing point than on any other car i've seen. the G54B is the more experimental of the Mitsu motors anyway, so it doesn't suprise me that they designed stuff stupidly. i mean, take the TBI (throttlebody injection) and jet valves on a turbo'd car. oh well, i love em anyway.
