hi, i'm just curious if anyone has ever tried to put a 4g63 into a Rx7? that engine is very powerful and doesn't weigh that much more.....i'm thinkin about trying this next summer...does anyone know if the engine would match up to the tranny?

 

Isn't the 4G63 engine mounted in a transverse position?

 

i believe so...i realize that there would be a lot of custom work done...i'm just curious if the tranny from the car would fit to the 4g63...i mean those engines can produce 250 hp with jsut a few bolt ones...reliable to...and doesn't weight that much more...jsut an idea

 

I had a friend with a turbo eclipse.i think he was running about 500 awd hp.the engine was completely rebuilt and had all things done.his best run was 11.3.With a broke *** tranny.In a 3600lb car.I tell you one thing it would put my fd to shame.

 

well...thats pretty much y i'm lookin into this swap.....i know a lot about DSMs....not a lot about rotarys

 

You can't be serious. You'll end up wasting alot of money, I don't think its worth it. Why not get a 1g Talon/Eclipse and stick to what you know. It just makes more sense that way IMO.

 

because of the weight advantage...a good 300 pounds with a full interior....plus...u'll still have a better weight distribution...also....the power potiental and reliablity is a lot better...the stock engine can handle a lot of power and still run everyday...plus i like RWD better than AWD or FWD

 

the reliability? Come on.

You could just make an rx7 with the same power and same reliability. You just have to take care of it.

 

Ok you have got to be kidding. Wankel7's TII is doing over 200whp and he still had a catalitic converter!!

 

okay...my friends daily driver...with 170,000 miles...and 3,000 into it...made 310 at the wheels...through AWD...so what is that say conservatively 340 or 350 at the fly....and he drives it everyday and beats the crap out of it...for the past two years....i've owned my Rx7 for 2 weeks...it have a 140,000 miles on it...had a brand new engine put in at 120,000....i have the papers from the previous owner and all of the papers for the maintence......and the car has overheated 6 times on me...plus it has left me stranded 3 times...hence the reliablity issue....figure this...my friends same setup....500 pounds less....easily low 12s

 

OK, and you think a Mitsubishi engine is going to be reliable? Who do you think made most of the electronics that we have the most problems with?

Do what you want, but power, reliability, and a good price are not something that you can ever have altogether. When it comes to those three you can pretty much only pick 2, and Mitsus haven't struck high on the reliability mark, ever.

 

a 4G63 is a horrible motor, they are VERY WELL KNOWN for spitting balance shafts resulting in dropping the cam belt and you get a great pile of bent valves, a stuffed cylinder head and a new meaning of piston porting.........

 

horrible motor....where did u get that opinion from....if the timing belt is put on correctly....there is no problem....and the 4g63 is very reliable....i've been researching the 1st gen 90-94 eclipse for over a year...i just fell into gettin an Rx7...love the car...jsut need a lot more power....i've been lookin into doin a LS1 with a 6-speed. and u can have all three things together...buy a 1st gen eclipse for like 3000...put a 1000 into it...ur into the 13s....so if that isn't cheap..reliable and powerfull...i don't know what is

 

you could check with buschur racing for info on making the 4g63 a rwd affair. i know he used a powerglide on the rwd talon and plebani's old 4g63 starion. the 4g63 is a great motor and very reliable, it's just the transmissions and 2nd gen crankwalk problems that suck. dollar for dollar though the ls1 swap is where it's at.

 

thanks a lot

 

LOL, I'm loving all the misinformation on the 4G63. I'm not convinced that a 4G63 is the best swap, but it's a very capable engine, and very reliable on the stock bottom end. Do some research, the wide bell housing 4G63 will bolt directly to a TII transmission. Hard part will be sourcing the correct block (not from a Talon, which uses a narrow mounting, need to find a van or truck motor). Then pull the DOHC head and turbo setup from a DSM. Should be a very easy swap into an FC if it isn't too tall with the cam covers.

 

yeah...exactly...i know the engine is great....but i'm going to do the LT1 swap instead....with a 6-speed....about 285 hp....with another gear....not to mention there is a kit to install it...so thats my best option....but i love the sound of a turbo....who knows...maybe is a few years when i start my career....i could turbo the LT1 or supercharge it, but for now doubling the HP and almost tripling the toque should do fine

 

My brother has an 1st gen Talon and all I have too say is its pretty quick he has intake, mbc, full 3 inch exhaust, 2nd gen manifold, and a 16g turbo, its pretty quick.

 

Wow... There are alot of people on here who are pulling all sorts of **** out their asses. I happen to be a Mits. tech... I have never even heard of some of the things people are saying the 4G63 is "known for"... The 4G63 is an awesome motor. The newest version (LAN EVO VIII) happens to be the most powerful I4 on the market.

 

thanks u....to many people on here...pull **** out of their asses about motors they don't know **** about...stock internals can handle around 400hp....only problem i know of wih the motor....is if the timing belt isn't done right...it could jump off and bend all of ur valves

 

That can happen to any engine that uses a belt and has a valvetrain... The only thing the 4g63 is know for is crankwalk with the early 7bolt motors. They were in very late model 1Gs 2Gs and the JDM LAN EVO I-III. The LAN EVO IV started the current style. The tranny on the left side and the motor on the right. The only thing they are known for now is destroying transfer cases. LIke the blue one that is in our shop now...

 

LOL....i wonder if that is the guy from buschur's fourm...some guy was there complaining how he broke his transfer case in his evo

 

Might be...Transfercase problems are starting to arise in alot of evos though... This guy has a full Tein adjustable suspension, tubo timer, enkie race wheels and Takata harnesses, with some other minor stuff.... While the T case out though we put in a sprung 6 puck clutch, light weight alloy flywheel, and some JDM swaybars. This thing HANDLED like it was on rails. took a 90 degree turn at 30 MPH, NO body roll whatsoever. It stayed perfectly flat.

 

damn..thats like my 7...if it ****** ran right...lol...yeah i wanted a DSm, but fell into a 7

 

I just found out that he (for warranty purposes) took out his fuel controller, FMIC, 3" exhaust, intake, BOV, and electronic boost controller...
