I would think an Esprit would be a walk in the park to work on compared to a Midget or Sprite. I swear the people who assembled those were midgets (er, little people) who had only 2 fingers and a thumb on each hand.

I've only had the engine out of the MKI once so far. I thought the front (car not engine) mount might have attached to the engine.

What would take you or me a couple of days of easy wrenching, would take the average 20 something on MR2OC a week. Hence the best $850 they would spend is to have someone else do it. Plus they wouldn't be out of their DD for more than a couple of days.

I'm not too worried about it, I'm actually taking my time and I'm pretty far into it. Nothing is dificult, it's just a lot of removing things.

I still maintain that I am a 20 something and I can see this project only taking a weekend, but it's a side project so I'm only doing a bit at a time. So in this case, Rob, you're right, it'll probably take this 20 something a week to do!

Yeah, that whole "front" v. "right" thing gets confusing in a transverse mounted engine setup. I mean the one over in the right of the pic that you can't really see 'cause it's too dark. Everything else is either transmission or bell housing. I swapped in a Fidanza flywheel and ACT clutch in this one in about 2 days while it was about 20F out in my unheated garage, so that limited wrench time because of the required "warm up" time.

Another forum for MR2's is www.toyotanation.com It covers all Toyotas and has an MR2 forum. Not really recommended though.

That said, however, my son just swapped in a V6 Camry motor into his MkII and found a similar UK forum for just this kind of thing. Pretty helpful. We did have an issue with the Camry motor and the Gen 3 Camry forum on Toyotanation was quite helpful.

The Camry motor seems to give the engine compartment plenty of room because of no turbo and shorter (front to back) block. He did a fantastic job; car runs terrific and it all looks very oem.

I disagree that a clutch on an SW20/21 is a E36 M3ty job...at least no E36 M3tier than a lot of other FWD applications. After putting a downpipe and upipe on my WRX last week, I miss how well thought-out the Toyota is. If you read up on a clutch job for the WRX, you'll see that this is also harder than an MR2.

Here is how I would do a clutch on an MR2 SW20, and it sounds worse than it is:

Put the front wheels on boards, at least 6" high and 24" long. Remove trunklid, engine lid and side covers and get them out of the way. It takes literally less than 5 minutes to do.

Remove rear bumper cover

Remove the exhaust

Hang brake calipers to the fender well,

Unbolt AC compressor and hang it (don't undo lines)

Disconnect radiator and heater hoses and clutch line at rear firewall

Disconnect the shift cables from the tranny.

Disconnect throttle cable at throttle body.

Disconnect engine->body harness from ecu in trunk

Remove the airbox, etc.

Attach a cherrypicker to the engine hooks

Unbolt the "strut rods" from the chassis

Unbolt driver and passenger side engine mounts

Pull the struts.

Unbolt the lower subframe

Lower the ENTIRE drivetrain and rear suspension onto the garage floor, onto a piece of plywood, or the top of a rubbermaid container, or onto a furniture dolly.

Unbolt the cherrypicker from the engine and bolt it to the recovery hooks on the rear of the chassis (this is why you remove the bumper cover. If your paint is crap, you might not care.)

Lift the arse end of the car into the sky and slide the entire drivertrain right out from under the car.

Now you have the luxury to comfortably replace the clutch and perform any other maintenance with ease. When you're done, roll 'er back under there.

It sounds complicated, but it's not. It takes about an hour and a half to do all that, if you're experience at wrenching and have a good tool kit, including air tools. 3-4 extra hours total.

You don't have to do it that way. You can pull the axles and tranny while the engine is in the car. Then you can spend three hours or more cursing, trying to deal with flywheel bolts and aligning a clutch and transmission on your back, in the dark.

If you're comfortable, you'll do better work and be less likely to get hurt. I have a sequence of pictures of most of this.

You can fix the top end problem fairly easily... but i agree with you as a whole. :)

On the passenger side, the water comes out of the quarter window vent louver. It doesn't do this on the driver's side. Normal? Seems strange to me.

Short of making a new, dedicated topic, does anyone know the answer to this? Here's a pic of where the water currently comes out, see the clean streak?

As far as I know those are not drains. They bolt to the unibody from inside the cabin with 1 10mm bolt. There is a little rubber flapper behind it. I think the TTops drain down the a-pillars.

If the top leaks, there is a toyota part for eccentric latch pin bushings.

Ok, I knew it seemed really strange. The driver's side drain down the a-pillar. Maybe I have a clog and it's routing the water above the quarter window molding.

Neither the MKI or MKII require the whole engine/transaxle to be removed to change a clutch.

You do have to support/hold onto the engine with all but the front engine mount (passenger side of the car) disconnected and tilt the engine/transaxle combination down enough at the back/driver's side to slide the tranny off.

Remove the axles and exhaust (but not the headers/manifold) and disconnect the things that will get "stretched" by the tilting.

When I raced a MKI and the machine shop was cutting the flywheel step wrong (resulting in multiple clutch changes), I did the whole job at the track in an hour.

In April I did my first MKII clutch change at the track and it was 9 hours.

Most of the "F" heads are designed for economy... but that doesn't mean they CAN'T perform.

5SFE uses a short duration cam, and "low compression". This allows good performance when attached to an automatic, and allows cheap gas usage. Get a set of longer duration cams, bump compression, do some chamber work, and get the correct management and a 5SFE should have no problem twisting, AND making power to 7000 rpm.
