You wont be able to see with your eye a warped rotor. When my front rotors were very badly warped I took them both off and set them on a flat table. They looked perfectly flat still. But I took them to the shop and had them turned on the lathe. He guy said they were so warped he had to turn them twice. If your steering wheel shudders when braking, it's your front rotors that are warped. Should only be $20-$30 to have them turned and they'll be good as new. Easier than buying new rotors.

http://www.porterfield-brakes.com/ I'm using the R4-S pads, which are great for street and autocross. But if you're doing a track day or an extended run down a mountain, once they get too hot they loose friction and fade quickly and wear away fast. I've often pulled over to let them cool for a minute and then start again.

If you don't want to upgrade to the larger 87+ rotors, that's fine. But the smaller '86 rotors will warp again a little bit easier and fade a little bit faster due to less surface area to distribute heat.

But you should still do the stainless steel brake lines. It's a easy switch and gives a rock hard brake pedal with amazing feel and control. Those old rubber lines that are on the car make the pedal feel much spongy-er. In addition, old rubber lines can burst and then your brake pedal will fall to the floor while you're coming down that twisty mountain. Brakes are the #1 most important system on a car, and if you're going to drive it aggresively, with more power later, you should have SS brake lines. It could easily be a matter of life or death. I know several people who have had their rubber brakes lines burst. Thankfully none of them were in a really dangerous spot.

The stock fuel pump works just fine with a 20v engine. No need to replace it unless you want a newer unit.

if you have to buy new rotors they should not cost you mre than 100 $ a pair or thereabouts as getting basic ones are cheap and easy, the mr2 from 88-89 or so used the same as a ae82 carolla, only backwards hub wise, but the rotors are cheap as

Yeah, it's hard to fine MR2 stuff in junkyards everywhere. Anytime a new one shows up at the local one here, it's completely stripped to a frame within a couple months, but nearly completely gone after a couple weeks.

I bet if you post in the fun section or on the MR2OC.com you can find someone in NY who has a 20v one and get a ride. Or you can always make a road trip to Idaho and ride in mine. Hell, if you came that far, you'd deserve to drive it too.

I've seen that done a couple ways. One of my friends mounted it essentially in his glove box, with the face sticking out of the dash beneath the glove box. Looked nicely done that way.

Years ago I was in circuit city and came across an infinity sub and amp all built together into a small box. It sounded fantastic (the best of all the display models there in the store) and I thought that it would fit nicely behind the passenger seat. But I never bought one.

You could always build a box that would fit behind the seat easy enough.

Even if you are a big guy, you can just stick it behind the passenger seat. Photos of your creation?

I did both. My first 20v swap I used the original 16v tranny with a new clutch because the engine didnt come with a tranny. My second 20v (after the first one died) came with a tranny and so I used it instead after modifying it to accept the shift linkage on the front side. The later model tranny shifted much smoother. It also allowed me to put the started on the intake side, which is a much easier spot to replace it when needed and didnt require modifying the exhaust header.

Oh, and the stock 16v clutch and pressure plate will work fine with the 20v for launches up to about 4500RPM. If you launch higher than that, it will slip.

also for an easier to find front brake upgrade you could use celica gts or gt? caliper early 90's it has a 57mm piston and the bracket i for 25 mm disks need redrilled or just use face lift... (also
cressidia brakets and calipers can be used of a certain year but cant remember, same caliper as the celica but hangers are for a 22mm [same as a facelift aw11] one weekend i spent WAY too much time in a pick a part yard taking parts off of one toyota and trying to bolt it onto a face lift aw11, i went to get the facelift calipers but was beaten to the calipers/brackets).. some good info http://www.marcmedina.com/MR2suspension.html
