Modified Accessory Belt Routing Complete (PICS)

What, you mean the factory timing belt tensioner pulley?

I want to see the engine bay. Any pics of this clutter free act of God?

Seriously. I bet it will make me cry every time I look at my engine bay. Soo much shit...

I don't remember what mounted to the hole used to fasten the pulley but it was obviously free. The only thing you have to do is add washers to move the pulley away from the engine block and once tightened you have to make sure the pulley is straight.

Very nice. I like the fact that the eccentricity of the stock t-belt pulley allows you to adjust belt tension. However, extra parts suck, and my method uses fewer parts.

Thanks for the compliments everyone. I'm pretty pleased with this mod, personally, and I'm happy that there are other people out there who are of a like mind. Thanks to 91Vr4n00maxima, by the way. In another thread of mine he mentioned that he had started but not finished doing this, and I thought to myself, "be damned if that SOB is going to have fewer parts than me!"

Valdas, I'm not sure what belt you should use. the 060390 is quite tight on my setup. If I remember correctly, the 390 has an actual length of 39 5/8 inches. On the stock crank and alt. pulley, a belt 39 7/8 would probably be perfect. With an aftermarket underdrive pulley, you might find that the 390 fits perfectly. If it is too long, there is a slightly shorter belt available, Gates/Napa/Carquest #060388. I'll bet that will fit. I'd like to ask everyone who's planning on doing this mod to let the rest of us know if they find a belt that fits better than my 060390. As I said in my opening post, it's not so tight that I'm worried about it snapping or putting undue pressure on the alt. pulley, but it's tighter than it should be.

VR4's-Kick-Ass, lawdogg, and others who have requested pictures of my engine bay: I don't have any recent ones. I think I've got some from a while back, before I did this mod and before I dumped the AWS and made a custom throttle cable to replace the old Diamante cable. I'll snap some photos this week.

Most likely, though, you guys will be disappointed. I still have the factory intake piping, and I have not converted to speed density yet (don't know if I ever will), so there's still some clutter. I can say however, that it's about as empty as you can get for a car with the stock MAS and intercooler piping. When Tim (*GT) and I went out for beers earlier tonight, I came up with a list of ways to further simplify my engine bay. Here it is, in no particular order:

FMIC: obviously this significantly simplifies the intake piping. Now that Tim and Chris (Multiades) have a tig, a front mount is a much more viable option for me.

Maft-pro or AEM: Currently, I have no plans to make more power than my 450s can handle. I've been tempted to get the Maft-pro because of its secondary fuel trigger (or whatever you'd like to call it) feature, but I hate to spend that much on what is ultimately an unacceptable piggyback for just that one feature. AEM is more expensive, obviously, and total overkill for my power goals, but it is awesome. Both, of course, would allow me to dump the MAS and run filter-on-turbo, if I wanted.

Relocation of fuse box to glove compartment: This is a tentative winter project. My current plan is to buy a circuit breaker or fuse panel from summit or pegasus and mout it in the glove compartment. I've deleted enough systems that 3 or 4 of the circuits in the stock fuse box are worthless anyway. But I may decide that extending about 60 wires is a major pain in the balls and leave the damn thing where it is. Rest assured, though, that if I do it I will have a thread with pics.

Fuel lines: Current plan is to run a single feed up the passenger side, split it to the rails, then run short lines to AFPR mounted where the cruise box used to be, then run a return down the driver's side. It will be relatively easy because my AWS is out. I may do this over the winter too.

Electrohydraulic power steering conversion: This sounds more difficult than it is. 2G Toyota MR2s use an electric pump to circulate fluid for the rack. Further, the MR2 PS system uses a vehicle speed sensor and a steering wheel angle sensor to vary the assist and to switch the pump off when the wheel is straight. Replacing the stock 3/S belt-driven pump with the MR2 pump is easy: find a spot to mount the pump, wire it up using a relay, and run some new lines, and it's done. I haven't figured out how worthwhile it would be (or how feasible) to employ the MR2 vehicle speed and steering angle sensors. This, too, is a possible winter project.

Unassisted brake conversion: This is probably the most difficult of the things I've listed, especially because I take my car to roadcourses. I can't sacrifice brake pedal feel the way people focused on drag racing could. I looked into this a while ago. I think it's possible to use a Tilton remote MC bracket in place of the stock MC/booster, so long as I can properly modify the pedal assembly. Another option, better but more complicated, is to install a complete floor-mount pedal assembly. But if I do that I will have left the realm of engine bay simplification. That such an assembly would eliminate the stock MC/booster is incidental. In fact, I would put the Maft-pro/AEM in this same category (Chris, I know what you are about to post about piggybacks, so don't bother with it ).

I got nothin' else. 3 of these, realistically, could be done by next spring--fuel lines especially, since all I have to do is buy the parts.

to open up the electric PS search a bit...the S2000 and hybrid ford escape also use it.


as for you having less parts than me....dont worry. i was going to fab up some retardedly elaborate setup to put tension on the belt.

Why would you do that when you can just use the special tool?

Power steering on the S2000 is a fully electric affair, yes? Is that true for the Hybrid Escape as well? The MR2 system is electrohydraulic: instead of a belt driven pump, there's an electric pump (I probably didn't need to explain that). A few other cars have similar systems, but I forget which ones.

To do the conversion, all one would need to do is wire up the pump and run a feed and return for the fluid lines.

I think I might actually mount the pump on the cabin side of the firewall, and then just run the fluid lines out to the rack. But hat may end up being more trouble than it's worth, and I'm not going to relocate stuff to really annoying spots just so I can say I did. Right now, the PS conversion is more of an idea than a realistic project.

[91vr4n00maxima]

yes. fully electric.

i spaced the fact that the mr2s were just an electric pump.

I can get you a true manaul rack conversion for your power rack if you want to go that way.

I am also currently ditching the ABS using brake lines and bias controller from a base model with no ABS

Bring it forth immediately.

I would absolutely prefer a manual rack. I know you've been working on it (you mentioned it in the a-arm/crossmember thread), and I've been meaning to PM you about it. I think I'll do that now.

I'm internet less starting today for a few days, I PM back my phone number. We'll work something out.

Cracking idea.
I just did this on my spare/test engine.
Works a treat with no grinding required at all.
3 trips to the local motor factors and having come away with a selection of belts on the final trip, I have a belt that fits perfect.
Only thing I have had to make is a spacer to sit behind the pulley to clear the engine, but 5 mins on the lathe and that was sorted.........

I weighed the removed items and the items and the weight saving was 13KG
