well today i over boosted and blew my head gasket. must admit beating that 300c while smoking from the hood was fun. i just dont know when to quit sometimes.

anyway i need a reason to tear into this car anyway and now i got it.

HERES MY QUESTION

wat will milling my head 20 thousandths do besides raise my compression????

since youll have the head off go ahead and send it into buschur. also just get a oem head gasket dont get a aftermarket one,and get some arp headstuds so it wont blow again.

why send it to buschur when i can get it milled here????

so wat happens when you raise compression

port and polishing? optimized flow, etc.. It wasn't a white 300c rt was it lol..... Leave those boost controllers alone :banghead:

I would send it in and get a head from them. Use yours as a core. That way you know its not warped. Also new timing belts, water pump and oil pump gears, not to mention the front seal, front cover gasket, head gasket [you want the metal one] and a new valve cover gasket and change the oil.

I wouldnt trust a machine shop in town with an import motor. My .02

kinda off white. i couldnt resist an early morning race especially since you started it. and it sounded nice

Next time dont play with boost unless you have a way to check your air/fuel and are able to make adjustments with tuning software. Playing with the boost is Russian roulette.

josh_zarbock

11-23-2009, 05:15 PM

vic how am i supposed to learn if i dont make some mistakes. and i do have a way to read my A/F.

also found water pump went out too so that might have had alot to do with it. i was watching my gauges and it wasnt getting too hot but if the water leaked out the water pump then my gauge would have not been reading correctly which im thinkin i just got it too hot.

gonna check my head to make sure its not warped. wheres my ruler and feeler gauge.

and i will continue to tinker with things.....its how i learn. and with my maf mod i can adjust my fuel and air mixture to make sure im not running to rich or lean just to let you know

because bushur knows wtf hes doing,since he has some of the fastest dsms in the world.He knows what to do to the head to make it the best for your car.

im telling you the afr on the controller you have now is not right.Get an aem uego and weld the bung in the downpipe for a correct reading.

josh_zarbock

11-23-2009, 05:29 PM

ok jspeed sounds good but wat im gonna do is rebuild this stock and find another motor to take my time on and build properly. that way im not rushing things.

as for this motor wat im gonna do is build it back stock and get a new wastregate actuator set at 13 lbs. motor had handled that all weekend so thats wat im gonna go with. use this as just a nice cruise motor.

josh_zarbock

11-23-2009, 05:30 PM

im telling you the afr on the controller you have now is not right.Get an aem uego and weld the bung in the downpipe for a correct reading.

so how is the reading im getting wrong if its comin from the exact same place

vic

11-23-2009, 05:31 PM

I tried to warn you though lol. Yes that is how your learn, a wiser way to learn is to research as much as you can before you make any adjustments on your car. Know the cause and effects of each action you take. Trust me I learned the hard way too. I just hate to see you get a nice ride and blow it up. But now look at it as an opportunity or excuse to upgrade the failing part lol :D

Do you have a wide band o2 sensor? DO you know what the readings are supposed to be? Look I blew up a brand new LS2 engine.. After that I installed a wide band and PLX gauge to make sure I knew some what what was going on. Also got a dash hawk which monitors a crap load of parameters. Right now I use all my free time researching how to tune. I sit on HP tuners sites all night, go through all the forums, study others tables etc.. Hoping to tune my own vehicles soon. Maybe a year or so.

Free information all over the web. Use it man, and good luck

edit: That screw on your 2g MAS isn't supposed to be used for engine management. And removing your honeycomb wasn't very smart either..

josh_zarbock

11-23-2009, 05:34 PM

didnt remove the whole honeycomb. it is a 4 piece and i just removed the one above the screw. must say that i did my research to find that mod and it fixed the problem i was having which is why i was able to boost past 13 lbs without fuel cut out

josh_zarbock

11-23-2009, 05:35 PM

a 2nd gen eclipse comes from the factory running rich as hell. so turning that screw out helped me out greatly to get the car running ideal

vic

11-23-2009, 05:38 PM

Just because you were able to boost more doesn't mean what you did was safe. You have no idea what the afr's were through the curve.

If you had done research then you would know by removing 1 or more of the honey combs can cause a very lean spot at around 4k rpms. There was a reason it wasnt allowing you to run more boost. You just tricked it to allow it and thus could have been the cause of your new found problems.

Again these 2 things might have made the car run better but was not a reason to up the boost without proper engine management.

vic

11-23-2009, 05:42 PM

And saying you leaned it out and then turned up the boost? I would have reduced timing, added a little fuel and then upped the boost a lb or 2 at a time..

It could have been detonating the whole time lol.. Hell My LS2 ran fine on a 150shot with no extra fuel. Then I stopped at the light and it was knocking like king kong under the hood... :lmao: Luckily I had a warranty and had it replaced with a gm crate engine free of charge..

josh_zarbock

11-23-2009, 05:47 PM

its not that easy to reduce timing in my car. gotta buy adjustable cam gears which are expensive.

i didnt lean it out either.....just got it running ideal.

and i only increased by a pound at a time. it handled all boost levels fine

like im sayin...im pretty sure my water pump leaking all my water out and my gauge not having water flowing across it read wrong and was hotter than it was saying causing that head gasket to blow.

vic

11-23-2009, 05:49 PM

You could be right dude.. No telling. Good luck

josh_zarbock

11-23-2009, 05:53 PM

im pretty sure thats wat happened cuz it was boosting fine and had no problems while i was racing last night. didnt know it was leaking out my ater pump.n while i was pulling the motor apart i found there was no water in it and my radiator cap was on so im figuring thats wat lead to it blowing. then the boost just helped push the oil out

vic

11-23-2009, 05:55 PM

Could have came out when you blew it.. I dunno. I am only going off what your telling me. Could have been all kinds of things.

ask for mike, tell him what you got and what you want to do. http://www.fist-racing.com/contact-us

He would be the only one remotely close around here that I would let touch or rebuild anything for a 4g63

by the way I have a brand new lm-1 wideband I was going to put on my 1g eclipse but never did $100 bucks and its yours
.I have some other little nick nacks you may be interested in just send me a pm

josh_zarbock

11-23-2009, 09:11 PM

well as for now that car is gonna get a stock rebuild with a 13lb wastegate actuator. then ill find another motor to build

josh_zarbock

11-23-2009, 09:22 PM

ok so i did research and found that at idle or cruise i should have close to a 14.7:1 and i have a 14.5:1 so thats good but found that i am running rich as hell still at WOT. so i do need a tune.

i have read in several places its better to run a rich mixture anyway is this true

jordanj

11-23-2009, 09:37 PM

every car is supposed to be close to 14.7 at idle and cruise.thats what stoich is.
You still never said what your afrs are at wot.

josh_zarbock

11-23-2009, 09:44 PM

reall my bad lowest i saw was an 11

jordanj

11-23-2009, 09:49 PM

yea thats pretty rich,you could go a little higher like 11.8-12.3ish.You should really look into getting dsmlink so you can actually tune your car.

josh_zarbock

11-23-2009, 10:14 PM

well i heard that garret might have the tuning software anyone got his number

ok i know wat i wanna do finally. i want this to be a nice 12 sec daily driver

jordanj

11-24-2009, 12:05 PM

get an evo3 16g turbo

josh_zarbock

11-24-2009, 12:28 PM

ok well im lookin to retain stock internals and haead gasket so will that turbo be ok with stock shit

josh_zarbock

11-24-2009, 12:38 PM

well that wastegate actuator is the way im gonna go for now. its cheaper and will alow me to do wat i want with out any huge modification.

that 16g is around 600 and not to mention i have to buy the install hardware since the piping is different and that runs 325. so that is out of the pic for now. might use that setup on my built motor though but i was lookin maybe to a bigger turbo than the 16g for my built motor

vic

11-24-2009, 12:52 PM

Gotta play to play. Building a motor isn't cheap either.

you know wat i have somethin to say.

no wonder noone really likes comin to this site anymore. whenever they come here and ask for help they get ppl that put them down or talk shit. im pretty sure this is the reason this is a dead website. in all honesty ppl if you cant help someone without being rude about it then just keep things to yourself.

i post on here to get help from ppl who know wat they are doin and wat the consequences are. sure i could research on the internet but its nowhere near the same as first hand experience. so i prefer to ask people wat works for them and wat doesnt. if you have a problem with that then im sorry. i learn better by explanations from ppl and their experiences and how they can explain it. me just reading some shit on the internet just doesnt sink in to well.

vic

11-24-2009, 02:22 PM

alright vic enough is fuckin enough fo real. im tired of you doggin on me. this is bullshit and from now on i dont wanna hear anything from you.

Jspeed thanks for your help and patience with me. maybe some other ppl need to learn how to be a little nicer and patient......VIC.

I dont have alot of extra money. times are rough right now. all i want is a nice daily driver that i dont have to spend alot of money on and when things ick up ill start droppin more money into another motor that way i still have my car to drive.

lol dude your askin and I am telling. All it takes is some looking around. I am not doggin on you. I am telling you to search and there is cheap stuff out there for your car. You had a nice daily driver, then you blew it up. I was trying to warn you not to do that, it was too late. I am saying I think your being lazy not looking around.

This site is for help but most of the time you get on here and want everyone to design your build, look for your parts, then you don't listen anyway. So before you go running your mouth sit back and look at what your doing. You being fucking lazy, and no matter what anyone here tells you you only listen to yourself and do what you want to do. Everyone is too nice and wont tell you the truth. I dont give a shit and will tell you like it is.. you can at least respect that lol.

josh_zarbock

11-24-2009, 02:45 PM

and i respect that in you. idc about other ppl and no i dont want them to design my shit. just asking and getting ideas. that dont mean im gonna go with wat you or someone else suggests. i am a stubborn person and love to learn for myself and see my mistakes. and as for lookin for things i do but i dont know the correct places to look in to find wat im looking for which is why i ask for help. better to ask for help than to not ask at all. and nmy car didnt blow up cuz of th boost i put on it.......it did cuz of a water pump failure which i now know after having someone more experienced look at it. im sure the guy i had look at knows way more than most on here with the exception of a few. its funny cuz he kinda looks like santa clause but he knows more shit than most. anyway i thank you for your help and if you didnt mean for it to come across as dogging on me then i apologize

vic

11-24-2009, 02:49 PM

That's cool dude. If you need to find something pm me. I just didnt want you looking dumb on this site. It just gives all the pussies more reason to go talk shit about you behind your back. lol Victoria life, aint it grand?

I wasnt there to check out your ride so I dont know what could have happened. Just fix it right the first time and replace key components while your in there. Do not skimp out. If you have to wait, then wait till you can afford to buy everything.

josh_zarbock

11-24-2009, 02:51 PM

ya thats wat i plan on doin. just getting this motor back together and once money picks back up ill find a motor like the one you found for me and mod that the correct way.

i do want to change my t25 actuator to the one jspeed found though just so i have somethin slightly more than stock 10 lbs boost. i know the car handles 13 with no mods to the fuel sytem or anything so thats wat i plan to run it at for now.

vic

11-24-2009, 02:56 PM

You should be able to run 3lbs with a boost controller. Just be responsible. Also dont know what your car has as far as engine management. Most at least run an SAFC to controller the fuel.

josh_zarbock

11-24-2009, 03:08 PM

well for some reason this boost controller is being gay and i cant keep the car at 13 lbs with it on. it keeps building up and boost spiking. i have run a boost leak test and have found no leaks. hell i even ran dye through it and still nothing so idk. i have tried 2 different boost controllers and both have the same issue so thats why i wanted to just change the actuator. i just like the fact that the car has all stock parts and beats most 8 cylinders on the road. ppl trip out when i tell them its stock everything except the bov.

i am goin to go ahead and port the intake and exhaust so that the holes line up and dont create resitance

vic

11-24-2009, 03:15 PM

is it an rpm based spike? sometimes it a settle spike where if you reach a setting it may go a tad higher and settle back down to it. I know on my Honda jet ski I had the bad controller and went to a homemade ball and spring type which held perfect over my $150 dollar one lol.

So is it creeping or spiking? any specific rpm? heck could be both. Why its good for you to research since you would know exactly what your car is doing. You should leave it alone for now until you get it running again so you can troubleshoot it more.

I know I sat out on the lake for 3 hours alone getting everything all fixed and holding boost right. From hoses, to controllers, timing, ecu, etc.. it was a pain. But once it was right, it was dead right and ran awesome. Pulled hard too. Couple people on the site got to ride it. Also running a larger intercooler allowed me to run a higher boost setting and more timing while staying on pump gas. I did run on race gas once but the lake was too choppy to get a top speed run in or any good flat run for that matter.

But it takes time and alot of troubleshooting, adjusting, testing, etc..

josh_zarbock

11-24-2009, 03:24 PM

well lets start here

the way the vacuum line are ran

line comes off intake mani down to turbo where ti tees off to the wastegate actuator. so i have vacuuum to both that turbo and wastegate actuator. wat i was told to do was remove that line from the mani and run my boost controller between the trubo and actuator. which i did. but no matter where i turn the controller it goes sometimes to 18 or 15 then settles to 10. depending on how much i put my foot into it is how high it goes. its like im controlling boost with my gas pedal

josh_zarbock

11-24-2009, 05:45 PM

ok just did some research to better understand turbos and must say it is way more complicated than i thought

vic

11-24-2009, 06:21 PM

was it connected to the top port or side on the wastegate? should be on the side port.
it should also be connected to the turbo compressor or anywhere between the tb and turbo.

Another question is what BOV is on there?

post a pic of your engine bay if you can
