4g63t swap tranny questions


Recommended Posts

Okay ive been reading this for a while now and looking all over for answers to 4g63t swap questions and a faq on the swap. but i havent been finding anything that answers my questions.

 

So this may sound stupid but why cant or doesnt any one use the stock cconquest tranny with the 4g63t swap. i figured the y are both mitsu desinged and should share mateable parts.i mean besides the bell housing not bolting to a 4g63t whats stopping you from using a conquest tranny?

 

 

and i say this simply because ive seen every other tranny on the list from toyota to powerglides on the list but tnot a solution to using the stock tranny.

usdm 4g63t all have the a slightly different bolt pattern than our conquest transmission, aka narrow block, the conquest is what we call the wide block. So you gotta find a rare wideblock 4g63 or 4g64 block to work with.

yeah okay well thats not new information to me i understand that that is obvious. but what about the input shafts etc spline counts in put depth . is that all shared between the 4g63 and its wide block conterpart...... if so how come i havent seen any one addapt a narrowblock bell housing to a conquest gearbok and mate it to a narrow block 4g63 seems like the simplest solution if possible and when i just thought oif doing the swapp before reading anything or falling upon the site thats what i was planning on doing. any takes on this why wouldnt this work if it wont.

whats wrong with the tranny im not trying to do a drag setup or any thing. i dont have to worry about new final drive ratios matching etc. im gunna put a max 275 hp light tuned 4g63 in it. so i dont see whats wrong with the conquest tranny that it cant handle it. i suspect it might have trouble shifting at the higher rpms that tranny is set up for but still uncertain. i plan to drift the thing so im not worried about power just feasibility. tell me in my application why would every other tranny be better than just using the mitsu conquest one. And if so i want to know why do people go and search out a wideblock so that they can use the stock tranny with out problems in doing a swap.

 

no mad just not seeing consistent information and geting tired. ive been tuning my car with the new 850 cc injectors in the eclipse and im still not done and its been like 24 hours in

you need 850cc injectors to make 275hp with a 4g63??????????????

for my swap for now im going with the d 50 tranny becuase i want to get the car up and running after that im going to look into adapting a mustang T5 to the dsm fwd turbo bell housing for the reason of they are cheap and every where and hold descent amounts of hp. if i didnt already have a built 4g63 narrow block i would have just looked for a wide block 63 or 64 and been done with it. but this is just my view on the whole thing

Mitsubishi (god love em) did not make their rwd transmissions with seperate bellhousings. If that were the case there'd be DSM motors in just about everybody's starquest. That is the reason you don't see stock starion trannies adapted to fit the narrow block. You have to cut and weld and that compromises structural integrity.

It is really simple to understand if you read it fully and thouroughly. All your questions have been answered on DJ's site. To do what you say is putting the starion guts in a D50 trans and only one man has done that effectively and he is Eric Plebani. He will not tell how it is done but is more than happy to build one for you and then they have not lasted more than a season even for him.

 

The 4g63 wideblock came in 87-88(for sure other years maybe) mitsubishi pickups and dodge D-50/Ram-50 AUTOMATIC ONLY.

 

I posted a link to one on ebay in the Ebay forum.

no man pay attention I dont have a 4g63t in my quest i have one in my eclipse turbo which is set up for 450+ hp to the wheels. ona to4e 57 trim turbo. tubular manifold.eagle rods and wiseco pistons arp studs the works. hence the need for 850cc injectors because 450 fuel cut at like 10lbs of boost with this turbo. you can get 275 hp tot he wheels with boltons and light tuning with stock in jectors. Ive been in the 4g63 motor since i was 13 so i know what im talking about. as far as conquest and starion. thats another story.

 

the wide block if i can find one ill get it. that seems like a simple solution but. i dont think its that huge of a deal to adapt a belhousiong to the gear box that works. I mean there s a right and wrong way to do that sorta thing . i msure there is a way to not totally compromise structural integrity.

 

But iu havent had a chance to look at it all ive been fooling around with the eclipse and working on the pro 4 car

 

so im gunna start lookingfor a wideblock 4g63 is there any differences be tween the wide and narrow besides the tranny mounting. like water jackets etc will a 4g6t head olt right up. timing bits ?

Same Identical block with the exception of the trans mounting. It only came in SOHC but all the DOHC specific stuff is a direct bolt on. Same bore, stroke, rods, crank, balance shafts, gaskets, seals, etc. The front oil cover is different for the SOHC as well as the water pump. Another good thing about the wide 4g63 is that they are all six bolt. I'll snap some pics of mine this evening.

Just a note, that you've also gotta look out for the flywheel diameters too. I managed to wedge a 4G63T into my Mitsi L300 van and attach it to the stock L300 gearbox, but had to modify the starter ever so slightly so it would engage with the slightly smaller ring gear on the 4G63T. This was an Evo 0 ( JDM VR4 RS) motor though.

OMG I found one a 4g63 wideblock i founf one in a 88 mightymax i guess. two of them happened to be next to a Plymouthlaser i found in the junkyard for parts one is a 4g64 and the others engine code read off as a g63b so Im gunna snage the g63b this week end and then grab a head too so Ill be ready to go turbo dohc 4g63 in the conquest really soon. and no need for a wire harness because the drift starion will be on a standalone complex.

Measure the bellhousing bolts before you buy. Should be 13.25" between the lower mounting bolts. I believe you have found a wideblock but measure to make sure. Might as well get the whole laser engine. You'll need the oilpump, timing components, oil pan, pistons, and if you use stock pistons I'd suggest having the squirters installed on the wideblock.

Glad to hear you found the wideblock. Hope all of the 2.0 DOHC parts swap over to it as easily as they did to my DOHC 4G64 wideblock. I'd recommend forged pistons and just leaving the oil squirters out. The money you'll save in machine work will nearly pay for the pistons.

 

Also be sure to check the bore and stroke to make sure it is the same. I heard that EARLY 2.0L G63Bs had a different bore and stroke. Not too sure of the specifics or if its really true. Just be sure to check.

 

To answer your question about why you cant adapt a narrowblock to a wideblock is becuase they are too close. 12.25" vs. 13.25" Its hard to move a 1/2" bolt hold over a half inch and not interfere with the original hole. You might be able to weld up the bellhousing holes and redrill, but you'd have to get almost perfect or you'd speed the death of an already inferior input bearing.

 

I used a D50 transmission in my first swap. I could only get the input bearings to last 6 months. Went through 4 transmissions that way in 2 years.

 

There is a guy on my site that just released a custom bellhousing that lets you bolt a Toyota Supra W58 to a narrowblock 4G63/4G64. It is selling for $350 through my message board at the moment. Visit my message board's Marketplace for more info. I see no $$ from this, I'm just promoting it becuase I want to support people attempting this swap and those making parts even when there are only a few people doing this type of swap.

 

And... "standalone complex" . haha.. you talk funny. Feel free to talk more about the drifting stuff. Just use aim: DJpowerhaus

You can put late guts of the big trans in the small early case ... You most cut the bearing hole for the bigger bearings ... Take the Quest bearing retainer use it ... Cut a hole for the fork in the bell housing ...Make a mount for the slave cylinder on the side of the trans ... Use Quest tail housing and forks and shifter...

 

There is a truck trans with the small bell housing and big guts .. I have one sitting here ... There's also one just like the Quest ...But cable clutch.. :?

hey guys im back in the process of building the motor. I stopped and one crucial point. puting 4g63 turbo pistons in the car. I mean im trying to make power so when i took a look at the stock g63 pistons they are very similar minus the crown of the g63b pistons. they are domed versus dished and should have noticable higher compression in the same set up im thinking a point or 2 compression points mixed in with the combustion chanber displacement on the Dohc head.only issues ice seen from examining the pistons is the skirts on the g63b vs 4g63T pison skirts is the g63b has mor piston skirt and less oil travel to the wrist pins. but same wrist pin to piston crown height and of course unsure about valve to piston clearance as the the g63b pistons lac the valve relief in the same locations as the 4g63 pistons which its not like I have never put valve and/or spark plug relief in pistons before. ( Commonly done on ihra and nhra rail cars on) especially on the rotella T team car of my professor. Im going to check the valve to piston clearance when i mock up the motor this coming week end. SO is there anybody who ever thought of using these pistons if so how did it go or if not why besides the reasons i just gave and explained.

 

In-turn Of BREmotorsports concord,NC

standalone complex.

 

If any one wonders why id bother to to put these pistons in the car when i could just get sum high compression pistons and throw them in the car. simple ... Im a motorsports technology major and im always been a budget racer. basically im a college student who has been taught life is a binary situation "You are either "STOCK" or "MODIFIED" ! which one would you choose?"
