where the doctor go Options

[Dr_Tweak]

Dr. Tweak is partially right.. I have noticed an apparent torque steer.. but.. however for me it goes in both directions.. not just to the left. When I get on the throttle in a low gear like 2/3rd.. The front end has a tendency to go all over the road.. to the left.. the right.. the steering gets real loose and flighty.. heh. I'm starting to wonder if I don't have a locking diff though over a limited slip. Reasons being is when I turn a wheel the other turns in the same direction.. even when I just had axles in the trans.. um another thing is if I turn the wheel while stopped to make a hard turn.. I'm not talking about full lock either.. just anything more than a slight turn of the wheel.. I'll need to slip the clutch a lot more or else the front end bucks around and gives me trouble.. and I've checked into every possible reason for it and found nothing.. other than the idea that i may actually have a locking diff.. would explain it.. differential isn't slipping.. so I have one wheel pulling more in the turn than the other wheel..

Another thing to add is the handling is much much better.. if I'm going through a tight turn.. instead of slowing down to hold traction I give it some gas.. that front end just sucks me through the turn.. and I've taken some wicked hard turns intentionally trying to get the car to slide out and no dice..

Oh and I'd consider myself to have a high power FWD vehicle.. dyno at 287whp at just over 290ft/lb.. if only I had some fuel upgrades.. I'd be well over 300 ah well.. this can be scary enough.. can't say how many times I've nearly crashed because of the steering getting all loose and pulling all over the road.

I'll bet you have an E153 with the MR2 LSD, don't you?

I'll bet that you are right. 95 JDM MR2 LSD.. was odd.. I had to trim ugh.. I forget how much exactly.. 1/8" or 1/4"... off of the driver side inner stub for the snap ring to lock into the differential.. On the inside of the diff there is no bar either.. it's a solid wall with one.. probably 1/4" hole in the center of it.

That's what I've been saying, the LSD is in the MR2 tranny is FOR A RWD CAR! LOL

It's not designed for a FWD which is why it acts like it's locking up on you and whatnot. This is why I don't recommend using the MR2's LSD with 3SGTE swaps in Celicas.

A v6 swap will probably only put down about 180hp/tq at the wheels.

So you're speculating that the loss to the wheels will be 45+ hp? That does not sound right to me at all.

The typical 1MZ makes 190 to 200hp, so 180 WHP is about right.

You'll obviously be making a little more (about 190 whp) because you have a 3MZ.

Hah.. you don't have to tell me this.. I was figuring that myself lately... mmm.. rwd mid engine car.. LSD designed for that.. Mmmmm.. Oh well.. it isn't a big issue I don't really care.. I've come to accept that it's one of the quirks with using this LSD.. and it's not some big issue that hurts the function of the car or transmission.

[Dr_Tweak]

Yeah, I imagine that it works okay for traction, but now here's a real-life example of why I don't use the MR2 LSD E153.

Now an E153 from a Camry or MR2 converted to FWD, with an ATB differential, that would be the best!

Right Collin?

*edit*

I've just realized, we've covered a lot of good info in this thread!

I'm using a 99 camry e153. If I was to do it over again I would go with an aftermarket LSD.. by the time u find/buy a stock LSD.. get axles for it... you've already paid for a good quality aftermarket LSD and maybe even axles

Oh, and you swapped in the LSD unit from an MR2? I gotcha. Well, the point made it still the same, like you said, may just as well have gone with a nice aftermarket unit in the first place.

Indeed.. HOWEVER.. I paid 400 shipped for the lsd.. 400 for the inner stubs.. so I got a pretty good deal.. I wouldn't pay more than 400 for the vlsd. The VLSD is also a bit easier to setup as usually you can just drop it into the trans w/o worrying about diff shim adjustment... But setting the shim up on the diff isn't very difficult to do anyway.. just need a good micro-torque wrench.

wow, you guys answered my question and more!

I LOVE THIS SITE!!!

although at times this thread got heated- lots of things can be learned from this thread alone. not a bad read at all, on all ends.
