The Works engineering one is lightweight, yes.
How light, I don't know.
What's the stock one weigh, I don't yet know.
Under drive, not sure, from the pics, there seems to be less difference in diameter between front and rear pulley sections than on the standard one, so possibly.

It doesn't fit. I was your test dummy. You're welcome :lol:

Doesn't line up with any of the belt circuits, plus the inner circuit is supposed to be 6 rib, not 4 like the Works pulley.

And no, you cannot space it out with washers.

Does it actually bolt on?
If so, I will take it.

May help you out there :D .
Just need to check if it's a 4g92 1.6L or the 4g15 1.5L :roll: , I would say that they both run the same setup.
I need to change out the belts so why not do all the pullies too :D .

Been a while.
Quick update, 2am.
Engine and box is in, mounts fabricated (using bushes, and bits of fto front lower control arm!), no contact anywhere there shouldn't be.
Need to locate a small alternator 55amp +, making new headers, rpw ones don't fit in space available (anyone want rpw headers? The y pipe has been cut immediately after the join).
Need to arrange new gear cables, and driveshafts.
Link G4 Xtreme being collected friday.
Water manifold sorted with speedflow black fittings for header tank.
Wiring has been stripped back, wires required have been identified, doing a little rewiring today (Saturday).
Will be using 6 individual pencil type coils, negating the need for any ht leads.
Not using the 70mm tb, something a little more interesting.

More pics soon.

So... what TB will you be using??
I was actually wondering how this is coming along, good to see an update.
Keep up the great work, I am sure many here are anxiously waiting for the completion.
In the mean time, pics please??

Throttle body; I have chosen an option you may find interesting, however due to the required design and fabrication, you just gonna have to wait for the pics. Rather show the finished product rather than my mock ups.
Have decided against supercharging, at least for now. Maybe revisit that option later on down the track.

Ok, yes, we all love pics.
Here are a couple for you.

Did you weigh the engine?
Does it concern you that the engine is on the same size as the driver, so maybe one side will be heavier?

Also, I feel like a noob for asking, but is that the water pump in the last 2 pics? If so, why are there those pipes leading out of it?

I would say that it is the thermostat housing and the two large hoses would be radiator hoses going to the radiator and 2 of the smaller pipes would be heater pipes to the interoir and the other 2 smaller pipes could be going to an oil cooler.

Headers, make an offer. Want the cut y pipe, or just headers?

Water pump is down in front of block.
Water manifold is what you see.
Fittings are radiator feed and return, heater return, two feeds for headers tank, one return.
Heater feed takes off radiator feed down near chassis rail.

Engine is in factory engine location.
It is a fair bit more central in the chassis than you would think, will get pic up soon to demonstrate.

Currently awaiting inlet mods, new exhaust flanges to build new headers.
Need to send my Link G4 Xtreme ECU to NZ for free upgrade, as CAN was implemented later, mine does not currently support it, so will not talk to AiM dash.
Need some time off to get into it!

Have you considered getting a different gearbox for this?
I think the FTO ratios are not well suited to the engine especially when racing

Such as? Any suggestions?
My car is half the weight of fto, so figured ratios wouldn't matter much.
Considering a sequential box later, but not right now.

Who was that guy that rallied the 6A12'ed Mirage? Didn't he use an Adelia straight but gear set Spetz?

Clint, you can mix and match some parts. For example I have a Cyborg gearbox with 4.625 FD and taller 1st gear, and 5th, so the drop between 1st to 2nd isn't as big, but the gap between 4th and 5th is pretty large, which allow the revs @100km/h to be the same as an FTO gearbox.
Maybe you'd change 5th to the FTO one so the gap between 4th to 5th would be smaller, but your top speed would only be about 230km/h.
What tire size do you plan on running?

These guys offer a sequential gearbox for the FTO:
http://www.modenaengineering.com.au/about_us.htm

Bennoz, Atmorally was his nickname. He had an adelia set but I don't think they were straight cut. He also had an ATS 5.0FD which he broke twice. Turns out they aren't very tough, at least in motorsport use. His top speed was only about 200km/h from what he said, but acceleration was blisteringly quick

Mix and match, ratios, lol.
With lack of experience with fto, having never even driven one, I have no idea how the ratios will suit my car as yet.
The stock motor and box from elise, top speed was circa 200km/h, with 100km/h in top gear sitting at 2500rpm.
At this point, I am guessing it will prob be about 3000rpm in top for 100km/h with stock box and ratios.
The original motor redlined at 7000rpm, the vvc motor another 500rpm higher.
Basically, I guess I am best waiting to see how it goes, and then deciding if I need to change anything with regard to ratios, fd, etc..
At this point, I am tickled pink to learn that my gearbox code signifies an lsd!

Stock wheel/tyres are 15x5.5 with 195/55/15 (205/50/15 at the moment) front, and 16x7 with 205/50/16 (225/50/16 at the moment).
I will be getting some new wheels, some Work wheels, 16x7 and 17x8, standard upgrade for Elise.
Tyres will be 205/50 and 235/45. Or thereabouts, depends what is available with the brand/model tyres i choose. (RE11S, Z1 Starspec, D03G?)
Prob will go with a sport road tyre on the larger Work wheels, and put semis on the standard wheels for track days, etc.

I was thinking, later, to look into a sequential 6sp box, such as Hollinger, Quaife, Xtrac, Sadev..
All quite expensive.. prob cost as much as the whole damn conversion will end up costing..
The Modena Engineering page has a few links, all say "coming soon"..
What is their FTO box like? Type? (Sequential?6spd?)
Is it as expensive as the other options?

Tell me more about hybrid mitsu box options?
Once it is in, I am not interested in doing something that will require other big changes to accommodate, such as replacement flywheel, clutch, starter, etc, all just to accommodate a different gearbox...

With those tire sizes you will be able to go well past 200km/h in 4th gear.

The modena gearbox from my knowledge is a sequential 5 speed, but don't know the price. The site is underdeveloped but I've heard good things about these guys and supposedly if you want info from them you should call and not bother emailing.
As for the gearbox options, you don't need to mix and match, the best one for circuit racing is the RS gearbox, which is basically the 1.6 MIVEC gearbox with an LSD and a shorter 5th gear. These are pretty rare though, and I think you can just use the FTO 5th in a 1.6 MIVEC gearbox for the same effect (this isn't confirmed though).
