All motor hybrid questions.

[Spyder Sean]

Ok bought a 96 gs spyder had a 2.4l sohc head. Just bought a 2.0 Dohc. Was going to turbo but decided too many problems as this will be my DD in the summer only! Would like to push At least 300 WHP. Need ideas for the head parts for now building one thing at a time. I have looked in to kiggly behive springs and 280 cams is this a g9od.start or not? If you could list parts below that would help me get this.goal and links please do thanks.

 

[dsmgst1996]

you should put the 2.0 crank and head on the 2.4 and turbo it .. Your going to have a long road getting 300 whp outta of that motor n/a.

 

[Moonlight GSX]

Won't the 4G63T (Evo 4-8) head fit on a 2.4L? The orientation of the belts should be the same, not to mention you'd be rockin' a 2.4 DOHC which sounds like a good deal to me.

Intake manifold would be facing the rad for starters. Can you do it? Yea. Is it practical? Nope.

I agree with all of this, except for the crank. What would be the point of putting a 2.0 crank in a 2.4 block?

The Evo 4g63 is flipped 180° in the engine bay compared to a DSM 4g63. So the belts would line up, but the intake and exhaust ports would be flipped. The DSM DOHC head will work on the 4g64 block and the intake/exhaust ports are on the "correct" sides.

See this thread for more details: http://www.dsmtuners.com/forums/cylinder-head-short-block/428378-newer-4g64-2g.html


OP- A 300hp NA 4g64 will be far less reliable and much more expensive than a properly turbocharged 4g64. You have 2 options here:

1. Swap the DOHC head onto the 4g64 block and boost it. While 300hp wouldn't be difficult, your limited by the NA pistons in the 4g64 block. So building the engine wouldn't be a bad idea.

2. Swap a 4g63 into the car. You won't have the low end torque of the 4g64, but you'll have much more room to grow with the factory turbo engine. You could use the 4g64 crank to build a 2.3 stroker, but that requires building the engine with aftermarket internals.

Destroked 2.1L Long rod. Not sure if that's what he's getting at, but its where I want it to be . Gotta love that R/S ratio.

It was more of a rhetorical question. I know you can use the 4g63 crank with a 4g64 to make a few different engine's (more info here http://www.dsmtuners.com/forums/art...stroker-destroker-long-rod-engine-basics.html). But those require custom rods and pistons to work. I just didn't want the OP to get the idea that you can simply toss a 4g63 crank into a 4g64 block.

Im sorry i should have been more gathered with my answer. thankyou for clearing it up with the links. I was really just shooting the option that makes more secne because of the currant plan made no scene 300 hp n/a 4g64 dd .
It could happen but there are easier ways then n/a .

I just bought a 63 head which will bolt correctly up. I Do NOT want to turbo exactly why I need people to post parts and recomindations of things to do to push 300 whp. I'm already building another.motor for turbo. This one I want all motor no cheater boost. People who build motors have more of a reliable car. No boost leaks. Less money depending on the build probably in this case not mine. But let me now I can do with the 63 head I have

 

[thomcasey]

Porsche got a max 208hp out of a 3.0l 4-banger in the 944S2. I doubt you will be able to squeeze 300whp out of a 2.4l without boost

 

[GPTourer]

Maybe you can find a '94 Galant GS somewhere. It was the only time Mitsu did a DOHC 2.4L in this country. I'm not saying the head will be that much different then a 4G63T head, but at least the pistons, cams, IM etc will be setup for an N/A application. Then you can figure out away to make it more powerful.

200whp is a more realistic goal though, I doubt you'll get anywhere close to 300whp without F/I or nitrous.

 

[Spyder Sean]

Damn this is makeing me wish I kept my Honda. I put a little under 8k in the motor and it wasn't boosted and pushed almost 320.

Agreed and all race motors built by TRD and Cosworth were doing around 12-13k RPMs to make those kinds of numbers with perfectly ported purpose built fully custom parts designed for that use only. TRD has a 4AGE motor (1.6L) that makes around 280hp (crank or break I can't remember which) at 12k RPMs. As for Cosworths record holder I don't recall exactly because I don't have a car I'd throw one of thier motors in.


If you really wanted to do this you would need a R&D team, a test lab, possibly hundreds of thousands if not millions of dollars and top people in their field. However I do think if you did the math you may be able to do around 240-260hp if you are willing to spend tens of thousands of dollars.

However I doubt parts past that range are going to make much of a difference and you are going to be faced with the problem of balancing and perfectly polishing and matching the ports for the best possible velocity.

Despite that I would love to see how far someone could get with this in mind and attempting to over come the problems themselves. It's really nice to see someone push budgets, parts, etc but it seems as though very few people here have any desire to do that and want to shit all over the idea of someone really push the limits of what's possible.

If you attempt it, I would love to be proven wrong.

Uh, what?

You can tell he is still a honda owner at heart!

You spent 8 grand to make less than 320whp?

Spyder Sean: what i am about to say is not intended to be rude or bias, but it obviously seems like you have not done your research very well, nor do you understand the potential these motors have. 8k ??for a honda engine, to squeeze out what a 4g63 does bone stock.

1. dsm are the most affordable factory boosted cars on the road/ with un-limitlessness potential.

2. if boosting is cheating. then your a sore loser. that word was created by people who don't like to loose, or see others win.

3. "respectfully" maybe your right, perhaps you should return to the Honda game.

 

[GPTourer]

Damn this is makeing me wish I kept my Honda. I put a little under 8k in the motor and it wasn't boosted and pushed almost 320.

Gonna have to throw the flag on that one. Almost 320whp all motor would put you at the top of the Honda tuning world with that Bisi dude, and you wouldn't be sitting here fooling around with trying to build a N/A DSM. You'd be up to your armpits in Hondas with paying customers beating your door down to work on their cars.

That said, if you are serious about building an all motor Mitsubishi, there's a thread here somewhere that showcases some very fast cars down in PR. No, they won't be as fast or as mighty as your Honda, but there are several 10s N/A cars down there, maybe faster can't remember. Might want to hit one of them up for some advice.

Mitsubishi's most serious answer to Honda was the 4G92 1.6L. It claimed as high as ~172hp stock but it was their "B16A". But it isn't the only way to skin the n/a Mitsu cat.

 

[Alex7747]

I think its been stated already but, the only way i can see you getting a 2.0l to make 300whp is to get your 2.4l and destroke it to a 2.1l and rev it past 10k rpm. get a High compression piston like 11:1+ but then you'd be really limited on fuel options. then the cams, not sure on those but they'd probably have to be a custom grind. then you would most likely have to make a custom intake manifold and exhaust manifold.. I say it can be done but it really isn't worth it when you can just slap a turbo on the completely stock motor and make the 300 and more.

Edit: i forgot to mention all the head work like bigger valves, porting etc.

 

[Miasma]

Damn this is makeing me wish I kept my Honda. I put a little under 8k in the motor and it wasn't boosted and pushed almost 320.

I think you need to provide us all with some details on that, if you want it to be taken seriously. 8k into a dsm would equal far more than just 320 hp. Its amazing how much money can be saved by researching and building smart.

 

[Moonlight GSX]

If it means anything I've researched 8k into trying to build a setup to reach on or around 700whp... but that's mainly the turbo/intercooler setup and a supporting mods (excluding engine, ignition...).

 

[Spyder Sean]

Ok for one sorry if I believe boost is cheating just my opionon if you don't like it then you can leave my discussion this post was here to help me put togather a car I don't know anything about. And some of you are helping me others are just talking shit. And for 2 I can some of you know shit about Honda's. Most Hondas that are all motor dependindbon the car take anywhere between 5-8000 $ to build I bought itbs if you know what that is that costed me about 2500$. And if you guys wunna look really stupid go to YouTube and type in otl raceing guys are pushing 320 who with over 12k in the car. Now can I get help or what. Haters goin to Hate

You're going to have far less $$ and a lot more reliability in a turbo motor. 300whp in a daily driver n/t is an "ambitious" goal. Not saying it can't be done, but like so many other things in life, just probably shouldn't. If you're determined I have just one suggestion forged everything. Get the compression as high as possible and only buy gas at a race track.

 

[dsmgst1996]

You could just build a 4g64 and throw 150 shot on it .. Your really not going to get much help dsm's are based on a turbo charged platform for the most part. We must be cheating stock !!! I dont see anyone hating just people try to stop you from throwing money away if i pulled 320whp out of my tsi with 8k invested i would be pissed I'm almost pushing that with less than 1k invested and the only thing holding me back is injectors.If you are stuck on the honda mind set there is no way to see life on the plus side of the boost gauge.

 

[Spyder Sean]

See I already have a boosted motor for it. So I'm trying to build another motor formy car I just received more then enough money to blow from a lawsuit money isn't an issue. If I really wanted I could buy a 100k $ car. But I don't win.a slend the money plus insurance would be outragus
