I want a modern 4g63!

This platform is just aching for a "modern" 4g63 swap. I was making 550 wheel HP in my 05 EVO on the stock block, and want that capability in my Conquest.

 

As everyone here knows, the 4g54 transmission bolt pattern is the same as the old old style "wide block" 4g63 used in early 80's auto tranny RWD vehicles, not the same as the old style "narrow block" 4g63 used in DSM's, or the new style 4g63 used in EVO VIII and IX.

 

Transmission adaptor plates can always be fabricated, but it would be easier if there is a RWD vehicle somewhere in the world that uses the new style 4g63 with a RWD transmission. I know there are RWD vehicles with the 4b11, but were there any RWD new style 4g63?

 

I am assuming of course that the engine to transmission bolt pattern on the 4b11 is totally different than the modern 4g63... let me know if I am wrong http://images.ibsrv.net/ibsrv/res/src:forums.evolutionm.net/get/images/smilies/smile.gif

 

Thanks,

Bill makes a narrowblock to r154 trans adapter for around 600 if in not mistaken.

 

There is a lot more to the swap than worrying about the transmission though, which is why most members havent bothered to mess with it.

 

Swapping in an evo 4g would be the same difficulty as swapping in a 2jz, or v8 or anything else (and probably more expensive)

What are the HP limits on a stock narrow block if you just plop it in without a rebuild? I never pushed my GVR-4 past 350 HP, other people said you could go further. I like the newer 4g63 power potential right out of the box, 550 wheel HP stock bottom end is great!

You can put a 1993 dsm block into a starion like I did.

 

You can put a 2g head or probably even an evo head. I put a 2g head, evo crank, evo oil pump and evo oil filter housing. Also evo rods and pistons could probably be put in, although I used aftermarket rods and pistons. Evo springs and valves and retainers could also be used although again I used aftermarket units.

 

Not sure what more you could ask for.

What year EVO crank?

 

Did we ever figure out why 2G DSM 7 bolt engines had crank walk issues, and if so was there a solution? Or should I stick with a 6 bolt engine? I know EVO VIII and IX are 7 bolt and no crank walk, with a pull type TOB on the clutch instead of push in TOB.

Any evo with a 7 bolt 4g63. Evo III, IV, V, VI, VII, VIII, IX.

a 1g 7 bolt engine does not crank walk.

 

Don't waste your time withe the r154. It's junk, I've broken 2 and I'm on #3. they shift like a 1910 john deer tractor that's sat in the rain since 1915. Either do a built t5 a tremec or t56.

 

The t56 requires a custom tunnel. A little more work than the r154 if I'm not mistaken.

As of his 2007 update:

 

"In the end, I changed the clutch to an OEM clutch, and my problem went away.".... what kind of answer is that?

 

If you want to make substantial HP you cant do it on a stock DSM clutch.... but his solution to crank walk is to use an OEM clutch???

The problem is thrust pressure from a heavy pressure plate. The harder you push, the more the crank "walks". With proper bearing clearance, you won't get crank walk on a manual. There is no issue with autos crankwalking.

You didn't state manual or auto, but I assume (making a butt of me and you) you want a manual.

The early Galant/Colt (70's) trans nearly bolts up to a 4g63. 3 of the 4 bolts line up. My brother is doing this swap now. However, the trans cannot handle over maybe 250hp. Who would trust 3 bolts to hold over that anyhow.

Bills adapter plate is THE way to go. He uses standard parts aside from the plate itself, and the crank coupler. The 2 parts that are unlikely to fail/wear.

Yup, currently a 5 speed car, plan to stay manual. Did the crank walk prone cars have jacked up bearing clearances from the factory? I know Mitsubishi never admitted to anything... but they switched to a "pull" style clutch for the EVO VIII and IX here... not sure when they switched over in markets that have had the EVO before us.

 

I suspect that being able to start the car without pushing in the clutch will help with crank walk problems as well. No pressure from clutch on the thrust bearing before oil pressure builds up has to help.

i wonder if the scion fr-s rwd 2.5l turbo engines could be made to fit :P

Not a big fan of the boxer engine's Twice as many cams to change out if you upgrade them, pain in the butt to do spark plugs, exhaust routing is a pain... all this is from owning a few WRX's in the past.

 

I would be willing to try a 4b11 with the RWD 6 speed transmission from the Hyundai Genesis Coupe. Expensive engine to source unless you can get a wrecked EVO X or Ralliart.

my opinion is that when you change the clutch out the clearance between the throw out bearing and pressure plate changes. You can damage the thrust bearing this way in my opinion.

why don't you just put in a rotatry engine? You'd have more torque.

I just realized from looking at cars at the DSM EVO shootout that it would be a pain in the butt to have the turbo on the drivers side instead of the passenger side. The Exhaust would have to cross over from drivers side to passenger side to mate up with the stock routing. But, the 4b11 on the other hand has the turbo on the correct side ready to rock!

The Scion engine isn't turbocharged right? P.O.S.

My P.O.S. 302 engine isn't turbocharged but it runs decent. ;) Back to the topic, what t5 transmission bolts to a 4g63? I am assuming an adapter is necessary. Since my car already has a t5 I am curious.

this is a finished T5 bellhousing, its the first one

It all fits out very nice, I should mock up the engine assembly to find shifter location but I need to finish the work for Dave ( screaming eagle) first

http://www.billsautofab.com/images/T5narrowblock98.jpg http://www.billsautofab.com/images/T5narrowblock103.jpg

I need to get ahold of Dan at compitition clutch and find the right bearings this week
