EJ20 Single Turbo - Can a 5spd D/R handle it?

[ezapar]

i do not know if the xt6 pressure plate will work or not......but it is one of the things i will try when it comes to putting the trans in.....

 

I have an XT6 clutch and pressure plate in my 5 speed d/r. It's only mated to an ea81, but I can't get it to slip when I just push the gas and let the clutch do all the work while climbing over something.

There was someone on here that put a twin turbo EJ and hooked it to the stock 5 spd d/r. It was all in a huge lifted wagon that he used for mud running. There's a video somewhere

[monstaru]

i am speaking of a 5spd behind an ej205, with 227hp stock(just what i read, not what i claim).if the starter spacing is the only problem with using an ej flywheel, i may try to figure that out......because all of this is lames.....

 

 

it just gets me ya'know.no one knows what a wrx clutch is going to do behind an xt6 pressure plate.but they want to theorize, it won't work, it won't work.

 

well ************ , on paper communism is perfect.

Now I'm not positive, but pretty darn sure that what I grabbed out of my pile was a EJ PP. It didnt match anything I had used previously, but it bolted right up to my ER flywheel/clutch. I havent had a problem one with this combo so far.

 

It could not have been an EJ PP. There is just no way to bolt an EJ pp onto an EA flywheel.

A "clutch" is a flywheel, disk, and pressure plate.

 

A WRX disk will fit on an EA input shaft.

 

That's the only part that swaps between EA clutches and EJ clutches. The flywheels and pressure plates are completly different.

 

Clamping force is generated by the pressure plate. This is what determines total grip.

 

Friction atributes are set by the disk, a ceramic puck disk will apply quickly, and not like to be feathered. An organic stock disk will let you feather the clutch. It's more progressive in it's lockup, which reduces shockloads.

Different disks have differing static friction, so they will change the max torque transfer for the same pressure plate tension.

 

What we're saying is use the best clutch disk available (which is not stock WRX, it's aftermarket high performance for a WRX) in an EA flywheel with an xt6 pressure plate.

 

OR run an EJ tranny and use a high performance clutch for either a 2.5rs (push type) or WRX (pull type) depending on what EJ tranny you have.

 

If you need lo range and selectable 4wd, use the EA flywheel, xt6 pressure plate and disk of your choosing.

 

If you can do with AWD, permanent 4WD(welded center diff), or just need a rear output to run into a transfer case, use an EJ tranny.

A are we talking a part time tranny?

 

That would hold up better (dependent of tires) then the OEM WRX tranny,

 

on the street your in 2wd (not that much power required to break traction),

 

off road your in 4wd and on loose dirt / snow, not much required to break traction there ether.

 

Shy of rock climbing / running HUGE tires wouldn't a 2wd tranny hold up better to spirited driving!?

 

Also I have a XT6 clutch in my push button 5spd EJ22 loyale and I've had no problem thus far (stock tires though lol)

ah ************ it, i'm goin back to ea81's......:lol:at least until i can afford an ej d/r.cheers, brian

Never said it was a EA flywheel, its a ER flywheel.

I assumed it was a EJ PP because it didnt look like any EA/ER PP I have replaced before.

But even when I was in the mudpit at WCSS11 with a carload, then up at Greenwater doing donuts, I never had any clutch slippage.

Yeah true, but if I wanted a high-power front wheeler I'd buy a rice-bucket like a Honda

 

 

And lets face it, nobody likes Hondas

Hey now! I got my most expensive speeding ticket in a honda. They're good cars, though I woudn't buy most of the new ones. They've gotten way to damn big. An old accord is the size of a new civic, a new accord is the size of a grand marquis. Screw making fun to drive economy cars, lets make overpowered luxo-barges.

 

True on the FWD being less strain on the transmission, but I found the EA front suspension to suck as far as putting the power to the ground. Something about the geometry of the front, it rises way up when you accelerate, the camber goes too far positive, and the tires loose grip.

wow....this thread is almost useless.

 

 

FACTS. Things I have done/tried/tested.

 

An EJ transmission swap is not hard. I did a lot of leg work when I did mine, and could not find any factory driveshaft combination that would work. the carrier bearing mount in EJs is further back relative to the transmission than EAs. so all speculations about transmission lengths goes out the window. An EA82 5MT driveshaft is too long for an EJ trans in an EA82, and an EA82 AT one is too short for much spline engagement at the slip yoke. it would work, but for how long......I wouldn't trust it, even with just EJ22e power. Transmission mount is different, but that's just a matter of getting your hands on XT6 crossmembers, or some fabricating, the crossmembers are really almost identical to EA82 ones, but with holes drilled in them and a third piece bolted between them (which has to be swapped for an EJ one anyway). Phizinza started working on modifying the starter enough to work with an EJ flywheel when he did his brat years ago. he didn't end up going through with it, but you could find his thread and then more information about it.

 

EJ flywheels are larger than EA82 ones, and will not fit in the EA82 transmission bellhousing as-is. Some grinding and starter relocation might make it possible.....but it's not an easy option.

 

An EJ pressure plate will NOT fit on an EA82/ER flywheel. period. the 6 mounting bolts between them are much further apart on an EJ. And even then, you'll need a push-type PP to work with any EA82/ER clutch fork, which only improves your clutch options a bit from the EA (cheaper, but not much stronger). if holding power is what you're after, converting to hydraulic and push-style is the way to go. Or just drop the cash on a Spec EA82 clutch.

 

An EJ clutch disc will work just fine on a 4WD EA82/ER. But upgrading the disc alone only effects how quickly it wears, not how much torque it can hold. Like I said, upgrading to a high-end WRX disc, but using a XT6 PP means it'll still be slipping all the time, but it won't wear as fast.

 

I ran a high-quality Beck/Arnley clutch kit for an XT6 on an EA82 flywheel behind an EJ22e in my wagon. it was in rough shape after 40k miles, and I ALWAYS let the clutch engage fully before WOT. That was definitely near the limit of what that kit could hold.

 

 

 

Educated Speculation:

 

I have seen zero evidence to suggest that an EA82/ER 5MT has any different gears (as far as strength is concerned) than your average EJ 5MT (excluding the WRX STi RA stuff). The gears are no larger. the only way they could be stronger is if the material was treated better. The only difference is the low-range gearset, which does add some complexity.....the input shaft certainly isn't the weak link on a single-range trans.....The rear transfer gears look a bit beefier in the FT4WD setup, but again, not really the weak link unless running RWD.

 

From what I've seen standard EJ 5MTs hold up to, ~225 ft/lbs is probably about as much torque as the gears can hold up to, even if used carefully. IMHO, any effort to get a clutch in there to hold that much is useless....

 

 

 

From what I remember, there are 2 cars that ran an EJ20t with an EA82 PT4WD D/R 5MT. one with an EJ20H (early twin-turbo), and the other was Albie's, with an EJ205 (USDM WRX). Both were lifted wagons with boggers. both were used hard in the mud. and both saw catastrophic drivetrain failure at one point or another.

yes, does anyone have one?
