4g69 is it a good motor? advice

[devlin]

my car has nearly 100,000 on it and in question whether i should go forced induction or not. sense it has aluminum heads do you think the motor isnt strong enough to live a long life? Right now i am in debate to just buy another car older with less cpu's and motor is made out of cast iron rather then have aluminum internals. what do you guys think?

[roman lujan]

Okay the motor is good yes the head is aluminum but the block is iron the crank is rated around 600hp. The internals are flimsy but can be removed for forged parts Wisco makes piston, you cam pick up rods off any manufacture that makes 4g63 rods. You can swap valve retainers from the evo 4g63 as well as the valves themselves self which is said to fit but no comfermation on that. You can port the head for 300 and you will feel the diffrence forshare. They offere cams, From delta and row. Yes this block is very good it has a The 4G69 is a 2378 cc version built in Shiga, Japan. Bore is 87*mm and stroke is 100*mm. Output is 162 hp (119 kW) at 5750 rpm (160 in the Sportback Wagon) with 162 ft·lbf (219 N·m) of torque at 4000 rpm. It has a cast iron engine block and an aluminum SOHC cylinder head. It uses multi-point fuel injection, has 4 valves per cylinder with roller followers, a one-piece cast camshaft, and a cast aluminum intake manifold. The 4G69 incorporates Mitsubishi's MIVEC Variable Valve Timing technology. The 4G69 is an interference motor like the 4G63.

Go old school if ur worried bout aluminum

[MACH1219]

if u want to go faster, buy a v8....lol

are u talking nitrous, blower, what? what psi? how much NOS? A lot of factors, low amounts of boost stock motor probably handle ok, if you get crazy, then you need to beef it up

[Slippercream]

lol. I think you'd be looking at a tractor motor if you expect to see cast iron heads.

The '69 is a good motor, if you're looking for stroke. It's got a good bottom end that you could mate with a '63t head from a CT9A Evo, with little modification. There are enough internal options out there to make this combination work, and it's been done many a time before.

Now as for working with the whole engine by itself and boosting, that's a different issue - there's more to making an engine push out effective power to yield at the wheels than just an engine.

[mivecpower]

iv been thinkin myself is it worth it to turbo or sc my gs. all i have right now is the money for the actual kit, but im wanting atleast 350 at the wheels so i know the internals must be done, but is it worth it to actually save more money and have it built up or more worth it just to trade up to the v6 or what? i love my gs to death and always said i4 is better than a v6 but now im starting to completely doubt it :/ plus after having the chance to drive my friends 03 cobra around town, i just feel slow, but i guess thats what happens when you drive a fast ass car and then get back into your basically stock n/a 4 banger lol but anyways is it worth it? to basicaly spend as much as the whole car is worth just building up the 4g69?

[MACH1219]

No, it is not worth it, and you most likely will seriously regret it. Just keep all these fantasies of a super powerful GS to exactly that, fantasies, and you'll be fine.

Speaking from experience, if you want a fast car, with TONS of aftermarket support, u start with a v8 mustang or something similar. But with the price of gas these days, and the move to all electric vehicles well on its way, i would scrap all plans of throwing thousands of dollars into a car to make it faster, unless your rich.....or at least have a second vehicle to drive and a garage to work on it in

[mivecpower]

but see thats the thing is i know i could go get a mustang or a gto or somethin with a big v8, i used to have a 76 nova with a 327 swap, super quick off the line, but its just one of those things like iv raced a mustang gt, from like 94, at the track and beat him by like half a second, and when they get mad and make me pop the hood and they see its not a v6, it just feels great to see their disappointment haha.

[roman lujan]

It's really up to you to deem if it worth it not some one else. Fully built you can see around 350 to 400 hp on full internal and a turbo which is quick for now but give it like 5 year and if there is any gas powered cars left they will be making alot more then that. But you can always swap out cranks and turn the boost up but by then it will only be a weekend car

[mivecpower]

so what is the cost to get a v6 put in? or even an evo engine put in, if thats even possible. im startin to think just trade in for a gto but i love my car

whoever you beat driving a 94 mustang v8 clearly has no idea what they are doing, in either working on the engine, or driving the car in a drag race. I wouldnt throw your hopes on that being a regular occurance

you dont want to do these things. You seem to have not considered tourque steer either, a result of high power and front wheel drive.

if you love the eclipse, but want more power, sell yours and buy a v6 version. Thats a start.....then if your still hungry for power, you start modding the v6.

[dsm2mivec]

Gto's are kill stories. I love the look and the sound but they aren't near as fast as you can get for that kind of money! There is a saying that I use for myself it's 'built not bought' my suggestion to you is get you a 240 or something and build the motor by yourself paying attention to little details and stuff like that and even if it's not the fastest thing out there you know what your doing! Other wise you go buy a car that's gonna rape ass and be like 99% of corvette owners :/ your gs can be crazy fast but you gotta have $ and knowledge and like everyone else said by the time you get it as fast as you want it's gonna be obsolete

[roman lujan]

Na that year modle of mustangs are pieces of shit I have lined up with a lot of them a each time I killed it the are rated at 215-225 form the factory so a newer car with a little less horsepower but a more aggressive geAring can take it out now a full bolt on gs should have no problem even if it has some mods

[MACH1219]

GTO's are junk. The other pontiac is bass ass, dont remember the name, G8 maybe?

he wants to go fast....hes not a mechanic or he wouldn't be entertaining these ideas in the first place. what are GT's eclipse, around 260hp? so thats a 100 hp head start over your GS, and you havent had to mod anything. its not financially feasable to make your GS powerful versus buying the GT.

[roman lujan]

Not to mention they are almost 20 years old with out of date tech and the motor has maybe atleast 100k+

maybe. i still say the stang owner was a clown. however, my stang memories are of this MustangWorks.com - The Ford Mustang Power Source! so I have forgot what the stock version felt like

out of date tech? can you be more specific? The only big common advancement from that era to now is variable valve timing, which wasnt as common on V8 engine anyway

[roman lujan]

Yeah that will make the diffrence new heads cams beefed up trany Full boltons. That's a whole different storie compared to a guy with some flow masters and a intake

[mwaterous]

Not to throw a wrench in the topic, but anybody here who really thinks electric has a chance of taking over in the next five years has been working in their garage with the doors closed. Just sayin.

[roman lujan]

Most companies have have hybrids and electric cars and it's only going to keep going look a Chevy the have hybrids and electrics now and the gas machines are going down the only real cars Chevy has is the comaros and corvetts which is the horsepower is going up dramsticaly and so is the price and the electrics are taking over the market

[mwaterous]

They've also been put out to pasture entirely I think twice before. Oil companies stand to make next to nothing off of them or we'd be driving cars powered by almost anything but already. I think the hybrids are out there just to make the stupid vegans happy, and that special happy group of folks in San Fran (sssnnnnifffffff, points if you catch the reference).

I'm not outright saying you're wrong (okay I guess I did, but I'll take it back for now), I'm just saying that I don't think it has a hope in hubris. If we survive the 2012 apocalypse, the 2013 apocalypse, and all the way through to the 2016 apocalypse, and we're both still on the forums here, I'll buy you a beer if it's all electric on the road. I'll even overnight a six-pack.

[MACH1219]

Oh, its not going to happen in 5 years, not even close, but I think eventually it will happen

[roman lujan]

Well it will get much more dominant

i am a mechanic, its just the only thing iv worked on are older model v8s, mainly chevys, and i know how easy it is to make power on them, stock bottom end get the heads p&p and good intake cam and exhaust and boom you got a cheap and decently fast car, used to have a nice nova before it got totalled, but anyways i just love my eclipse but yeah i dont really know anything about these new cars. but at the same time i know for the same price as just the turbo kit for a car like ours i could build a 500 hp v8 without nitrous or anything. now i wish i woulda just bought another old school with my insurance money

[MACH1219]

so sell your car and buy something else. no biggie
