How to find TDC? found a method that might work

[jmartinez1228]

The car has a 420a which has a mls gasket from the factory. The oem style gasket is perfectly fine for this application.

ah see I remembered it was 420a and my first thought is a 4g63 hg issue . Oh well thanks for clearing it up. Editedededed my last post.

The guy I bought it from had a cometic head gasket on it, he told me to make sure I put one on? Should I go with his word or stock.

I got a 10", 2/3, 5 ton puller. I rented it, get all my money back if I return it. Is this the right size, I asked for a 2 1/2 jaw puller and they said that was what I needed.

OEM MLS HG, end of story.

Obviously the cometic didnt do you any good.. OEM will be perfectly fine.

if the puller works it works.. i do think you got the right one.

Like we said, you CAN re-ring with it in, but keep in mind not your pulling all the pistons out, disturbing the rod bearings, now you open risk of contamination, or an "accident" when you re install them. If you did that , it would be a good chance to inspect them, but you may find something you dont like. IMO choose a path and do it.

Either: Pull, inspect , fix OR do a HG and check the head, and leave the rings alone.

 

[GSTurbo1]

OK... I think the HG from high heat due to the fact that the fans were not working at all in the car when I got it. I'm pretty sure this is the culprit for the bad head gasket.

 

[glowryder]

Could be.. At this point, id ask myself..how well did this really get build.. I mean fans not runing , etc.. how the hell did some one let you dyno/tune the car if your fans were not working...

Imo.. you say you want to buy another modded car.. this is exactly what happens when you dont build it your self. you get some one elses crap. Keep that in mind.. its just going to repeat itself.

 

[GSTurbo1]

The guy that originally built it had the fans wired to turn on whenever the car was on... I mean it was a good build when the original owner had it, just no telling what has happened between levi's hands and mine. You know it has to be an efficient build if on 5psi pushing 233hp.

I'm not trying to disrespect you, I know it was a great build it was just people that did not know how to do proper maintenance on the car after the original owner sold it.

The wiring aspect is a different story, it has been an on-going battle for me to make the wiring legit. I feel like a mad scientist trying to decide if I should cut the red wire or blue wire in order to save the world.

 

[glowryder]

I thought u bought it from him.. so , then you should know what happend? I think some one wired it wrong or dicked with it. no reason for it to quit working unless one of the 2 reasons previously stated. Regardless, thoose numbers are inflated, but thats neither here nor there.

Claiming 20~25 Hp per PSI gain is outlandish, esp on that turob where its not at its peak effiancy..Again not here or there.

Get the HG fixed and fans fixed and enjoy the car till something else happens is my vote.

I thought it was to good to be true, seems solid when its running good though.

Anyways, the reason i;m so hesitant on the HG replace is that it has been bored or so LEVI said when he did... "its been bored .020 over". Does this mean I will need to get a HG that will fit accordingly? Or would a stock head gasket work? I don't know if you guys factored that in.

I think that had to be on 8psi which is the wastegates spring pressure... don't see how the only pushed 5.

Oh and I got the fans fixed, I put them on a switch.

"I'm not trying to disrespect you, I know it was a great build it was just people that did not know how to do proper maintenance on the car after the original owner sold it. "
I thought you got it from the builder, thats where i was lost. so if it changed hands and your 3rd person, then now i see why theres alot of WTF .

"I think that had to be on 8psi which is the wastegates spring pressure... don't see how the only pushed 5." thats what i was going to say, Hahn offers a stock 5 and 8 spring, however, they usually keep boosting past that a few PSI. So i bet even tho u have a 5 psi spring, you boosting at ~8+, which would make alot more sence.. Also depends on where your masuing the boost, and they dyno. but id be more inclined to belive thats an 8 psi +car.

.020 is nothing to Worry about just get a Mopar MLS. your good to roll.

 

[GSTurbo1]

Ok cool deal man... just wanted to do it right!!! Yeah the car has been through 3 other people since the builder , if you would have rode in it when I got it compared to before i did this tear down you would be like WTF this isn't the same car. I went from running a 2011 mustang get from a 40 mph, getting lead by 6 or 7 car lengths to pulling on him by almost a car length.

 

[glowryder]

well given that.. I think you need to decide what you want to do with the car. If your going to keep it for a bit, and maybe add more boost (not sure whats stopping you), then i would say Rebuild the engine.. Have it gone thru , get new bearings and rings, Mechanical tensioner etc..

 

[GSTurbo1]

I think I am going to build and turn up the boost. The main issue that was holding me back b4 was bot being able to get traction. I turned my MBC up to 15psi and at3rd gear 60 mph punch it blows the tires off. I feel like there is no point in having all the power with no way to control it... I need fat tires.

 

[glowryder]

No.. you need Clutch, LSD first.. tires wont help if your a 1 wheeled wonder.

Id also recomend a crank scraper and windage tray the way you describe your mountain drives.. these pans like to have oil starve conditions.

Imo- do a rebuild. While your in there add the Crank scraper/Tray, LSD and clutch. THEN your call will move more efficently, then maybe get a et of nitto 555s

Your a boosted 420a, Traction problems are the story of our lives, you wont be able to fix this. this is where Boost by gear/TPS is nice. Im not sure if you have that option on your MS unit. But A nice EBC would work too..you dont need 15 psi in 1st n 2nd. I plan on staggering, 8 Psi in 1st/2nd then 18 Psi in 3rd onward.

looking at your profile, you have along way to go... Id also suggest Poly motor mounts, Al fan and some pushers to open up the space you'r turbos in to just name a few. Maybe get a few more monitoring tools..Like a water Temp guage.

not trying to talk shit but i do not believe you made 233 on 5psi, an sounds like your car was halfway built right, probaly the reasoning it has been passed around, imo your best built is to take your stuff to the machine shop an get it all rechecked and go from there. Clutch, an lsd, would definty be an upgrade to be looking into if your wanting to make any good power (or else you want be putting to the ground efficiently an your clutch will not last long, trust me as i know)

haters haters haters.... hahaha. Levi (the guy that built the car) said everyone was real shocked when they dyno'd, they did several pulls and this was the average. I'll show you the link straight from TDC

Bam! Get of deez son... everybody has to hate when it comes to the 420a

I have nothing useful to add, but I did when the OP acted like having the Hayne's manual was any different than drawing pictures on your toilet paper with your feces.

Actually...I will add something useful, as the owner of 2 boosted 420a 2Gs...let me promise you, that there is no point in power that you can't use.

I honestly want to take the hanes manual back, I feel like i would be better off using google. . Anyways sick spyder man, I would give anything for this car to be awd. I dont feel like dropping all that money too make this thing get a little better traction, its just going to be a mountain car... no drag car.

I got to the point of taking the crankshaft pulley off and about got in a fight with the jawtooth puller. That damn thing is the devil, I think I got the one that is a size too big. I'm going to research just to be sure though

 

[99 gs iowa]

hater? i have no reason to hate on your 420a i have my own, that runs an spools perfectly, just saying your number are incorrect is all

Yea, we discussed it above, it must have got lost.. It may have spooled to 8+ psi for those, numbers which would make alot more sence.

If this is a mountian car.. then a crank scraper and windage tray is a MUST.

No ones hating, again, those numbers are not close to what others witht he same or better setup have gotten @5 psi. thats why your getting called out. Its no biggies, its clear it was pushing more. no worries.

GL with that Pulley its a bi***, i would laso recommend switiching back to stock. UDP isnt the greatest thing for a turbo car, not to mention, it has no dampening ablilities like the stock one..

You never now what lies within the beast... . Yea your car looks sharp man.

Mitsubishi one of these look good?

 

[glowryder]

Thas it, talk to Kevin, tell him Cody sent ya.
Get the crank scarper and windage tray/baffles. those are critical for oil control when not going in a straight line.

why your at it, might as well get teflon upgrade.

 

[GSTurbo1]

ok cool... i think i'm going to try and make this thing bad a$$!

I was underneath my car cleaning all the excess oil off the block and noticed a pretty cool little tag on the side of my clutch/transmission side of the block. It said New Venture Gear and had a bunch of numbers stamped under it. Any clue what it might be?

Nevermind... i guess it's just factory? Or at least that's what I pulled up from some research. It looks like a neat aftermarket tag.

 

[glowryder]

its a stock trans.. IE NVT350.. NVT = New venture Gear Trans.. Its stock.. Sorry to burst your bubble.

Crank scraper/windage tray/Baffles are a must for you, the rest is all optional..Be prepared to have deep pockets. Your current build is what I call Level 1, Entry level, with a nice EMS, minus the fact its MS1 .

 

[GSTurbo1]

Pockets don't go too deep man, . I don't want a drag machine just a fun weekend driver.
