DSM Go Boom!

[Render]

So I was pacing in my drive way about 2 days ago while talking to a local performance shop that specializes in 1G DSMs, and I noticed some oil spots under my car, when I went down and when I leaned down and checked the fluid, I realized there was antifreeze in it also. I went over to a friends house and used his compression tester, and the results where (4-3-2-1) 110-90-80-100, so I am assuming head gasket...

...So my question is, what brand/size head gasket do you recommend?

On another subject, this summer, I want to build an engine this summer, the only thing that I know I want to run is 2G turbo pistons, what else to you guys recommend, I will be doing this completely seperate from the engine I have right now, so I will need a differant block, and the works, I am thinking a SS tubular manifold, and a friend recommended a steel block, what is the advantage of a steel block over a cast iron one, and where can I find blocks for the 4G63? Also, I noticed when looking at a 2004 Mitsubishi product line up book from a car show, that the Evo has a 4G63, what is differant in it that makes it put out so much HP than my 1G Eclipse? And could I put an evo valve cover on my Eclipse engine? Thanks guys, im open for suggestions, so please hit me up!

if your going to build your motor, do it right. You will spend BARELY less on pistons and rods if you go with 1g big rods and 2g pistons. Its a waste. That can handle WAY less power than say wiseco pistons and eagle rods. You dont need a crazy block. I know ppl with over 400 whp with stock block built internals. Just get a 1ga 6 bolt block, hot tank it and make sure everything is square and sealed. Build that, use ARP studs, sheet metal gasket set, and be sure not to forget the head work that you should get done. At least get porting done while the head is off.

there is a CRAZY awesome shop in stpaul mn. They are called QPR. I would advise checking them out. Ive seen them do CRAZY crap, and as far as the tubular manifold goes... piss on that. Get a stock 2g manifold and get an external wastegate for it. Shoot me a pm if you want more info on that shop. Later

dont forget 1mm oversized valves and springs and retainers.....gotta good ones.

Just buy an OEM HG from Mistu. What symptoms do you have to lead you to believe the HG is blown other than compression? Does your oil look like chocolate milk? Oil in your coolant? White smoke boiling out the exhaust? Overheating?

As far as the new engine goes, how much power are you looking to make with your built engine? If you're not planning on making 500+ HP, you'll be ok using stock 1G big rods. All 4G63 blocks are cast iron, they're not steel. Also, the EVO 4G63 is basically the same motor, built to rotate the opposite direction (oriented 180* opposite in the car). You can't use the EVO valve cover. Why would you want to anyway?
Not to be an ass or anything, but from the questions you've asked, I would suggest doing a LOT of research before ever beginning this project.

 

[90LaZeRrst]

well said, A LOT of research. But yea, why use those rods / pistons if for another hundred bux or so you can get REAL after market ones. You have to get the rods or pistons machined to accept one another.. waste of money. And when you build an engine, dont half ass ne thing because all you are gonna do is redo it later. So go big in the motor right away. Good luck, pm me if you need ne thing.

I know I need to do a lot of reasearch, thats why im here asking you guys questions. I wanted to use the evo valve cover because it looks cool,

As to using the stock iron block, should I just buy a junk yard engine then?

Oil is still black, but with white creamy substance in it, car seems very slow since right before i noticed the oil, no smoke, no oil in the coolant, temps are slightly hotter, but still basically in the middle, but i was told this is just the beginning? What else would it be? What can I do to find out.

Thanks guys!

wut year / model is your car? Is your timing possibly off from jumping a notch or something?

1991 Eclipse "GST"

I sure as hell hope it isnt off

I think im going to order a complete timing belt kit

I ran 1G rods/2G pistons in my last DSM, and I will say they are far from a waste. I noticed alot better power out of boost with that setup.

Take into consideration your power goals. Are you shooting for 350-400whp or going all out? If you plan on running, lets say, a B16G, 20G, even a 50 trim or FP3052 with all supporting mods, then the 1G rod/2G piston combo would be ideal for you. I found an extra set of used 1G 6 bolt rods for $100 and a set of used 2G pistons with about 55K for $100, so this is proof that the 1G/2G rod/piston combo can be had for cheap. Sure they dont compare to forged, but if your not going all out, you dont really need to go that route.

I'm not too crazy about it, I want about 300-400hp at the wheels, but I want everything to be new. What would you guys suggest with that in mind?

Done.

New 2G pistons from the dealer are like around $300 (w/or w/o rings I dont know). You can use your stock 1G 6 bolt rods.

Use this here.

Speaking of doing your research i think you should do a little more before you go posting this crap.

evo 3 engine is the exact same as a usdm engine but compression is up to 8.5:1 and uses a bigger turbo. As far as the 1g big rods and 2g pistons, there are a great budget setup and hold up quite well. I currently run that setup on a 14b and can hit 12.6 so tell me its not a good setup. Now i will admit that aftermarket rods and pistons are great if you wann make 500hp and beat the shit out of it but im willign to bet you dont need that much.

if you want to spend money on aftermarket pistons and rods then you might as well go buy the crank and build a 2.3l stroker you will be happier that way

If you would notice he mentioned the 2004 Mitsubishi Product Line Up. That would mean the EVO 8, which the motor is 180* .



The comments with the 1g rods/2g pistons is all on preference.

I picked up a set of 1g rods for $70. It cost me $112 to have machine work done so they would mate. That's $182 compared to $500+ for forged internals. I've had no problems with mine, and would do it again for any street driven application in this car.

 

[90LaZeRrst]

where do you guys do your shopping? I can get eagle rods and JE pistons for 400 dollars . And how do bigger pistons enable you to handle more boost.. that makes no sense . 1g rods ( which he already has) is wut matters. HE can get some real pistons for around 200-300 bux done deal. I guess its a matter of preference, i dont do things half assed. If im going to do something, i do it right the first time versus wasting more money later. But thats all i have to say about any of this. Im out.

 

[out there]

he might not need pistons for a while, local guys have made pretty big hp numbers with stock 6 bolts (400+)

Wow, aren't you in the other 2G piston/1G rod combo thread??? Same crap, different thread...

1. www.dsmtrader.com , www.thepartstrader.com , classifieds here. Im sure tons of people here use Ebay.

2. Show me where you can get Eagle rods AND JE pistons for $400 together. $400 for Eagle rods I can believe, but for JE pistons or both together for $400, I call BS unless you have some illegal connections.

3. "Bigger" pistons in a compression ratio sense allow you to make more power using less boost. Overbore pistons change the compression as well, but are usually done when having a cylinder block honed.

4. "Real" pistons? Do you even know what the disadvantages of using forged 9.0:1 pistons vs. 2G pistons are? Please tell me if you do because at this point, Im convinced you dont know WTF you're talking about.

5. Whats half assed about using 2G pistons? Maybe you were in to Honda's or something and think 12.5:1 Sp00n pistons are t3h HaWtN3SS!!! My god will you please come back here and show me you know anything about building a 4G63. Do you figure spending more money is what's gonna get you fast? Do you figure tuning is a piece of cake and the more money you spend on a part, the faster you'll be? Did you ever take into consideration that certain people have certain time/hp goals?

6. Thanks for your prescious .02 Gangsta, please take it out the door with you as you leave.
