ZZE122R, Rotrex S/C?

[onezzdashfe]

i hope im not starting up an old thread, i have had a quick look through but no forum seems to have the answer im after, i'm looking at supercharging ol'faithful (03 1zz-fe corolla sedan) as far as i can find for price, servicing and longevity Rotrex seems to be the best option (C30-84 or C30-94 w/restriction sleeve) but the issue im running into is how dang tight the enginebay is on the pulley side, i had read on another forum (no one had posted for about 3 years, so i assumed its dead) that someone with a similar car moved the alternator to the other side, but left no pics about how he did this, whether he added extra tensioners, what the bracket he was that he used to mount it, nothing, so i was wondering if anyone has on a whymm moved the alternator to another spot to free up this area for a s/c option? ohh another reason im going for a Rotrex is how quiet they are, i love sleepers!

if anyone is able to help shed some light that would be much appreciated!

as you can see from this pic ture there aint much room on the corolla's

so what i have thought of for 2 options is number1 easier option but trying to find info on whether i can do this with a rotrex is to run an extended shaft from this side over to near the gearbox and mount the gearbox

seems to be an easier setup then option 2, which is, remove the engine completely and mount the alternator on the opposite side of the engine and mount s/c where the alternator was.

i see option 1 as the more viable, it adds in shorter intake piping that could also double as CAI just by cutting a hole in the plastic in this next photo

but i cannot find out any information from rotrex on whether i can use a direct extended shaft to their unit or whether its going to need another pulley and belt!

[onezzdashfe]

the main thing i really need to know is there a way i can run an extended shaft design on a rotrex or will i have to use a secondary belt design eg

(engine side) Pulley===========s/c

or Pulley==========pulley belt s/c

with the s/c sitting lower, and having the engine side pulley above the alternator? a good example of this is off the Vortech site

but i can't decern from their information whether they sell this as a spare part, or if its custom made, and also which of thier s/c would be the best

then that adds i need to get another tensioner and also work out the pulley ratios?

Hey mate,

Think of it this way:

THe engine bay shown above (ideas pic) is a LHD (left-hand drive) car.

which means the side where the pulleys are on the opposite side to ours (Jap-built).

For your application, you would need to have the rotrex the other way around. Custom mounting points for it, and correctly sized belt, and you would be good to go.

If there is more you want to know, Flick me a PM.

Motors dont usualy reverse between lhd and rhd. thats just a Honda

[Evo7]

no, upon closer inspection, example pic is honda...

google Scion XB s/c

to "Evo7" and "Reliable" comments:

please keep on topic, i don't want this thread turning into another troll thread about what car this engine is from, and keep this thread about me asking questions about Rotrex Superchargers and whether this

setup is possible with rotrex superchargers, cause if this isn't viable then 3 options are available 1: use something like this but with another pulley and belt to drive the s/c(which means more load on the motor) or 2:(the worst case scenario((the way more expensive option)) )i have to rip out my engine to move the alternator to the firewall side of the engine which is very low on the block as well! or 3: move some things to situate it!

As you can see from my previous post like All corolla's of this model my pulleys are on the Right hand side of the car, and just to add my car is RHD (Australian Model).

So the only thing that really moves is some piping for a/c and p/s from stock. as it is im waiting for a reply from a guy in England who's T-sport 2zz-ge corolla has this model s/c, im just waiting to see where he moved to expansion (radiator overflow) tank to and whether he moved to alternator, because it's not visable in his videos, and i can't find any local 2zz drivers who will let me pop their hood to check local of alternator!

Hopefully im not wrong with my measurements, i (i really do think things out before i even think about buying them, so in other words, another month of measuring certain parts of the engine bay before i really contemplate buying this s/c), i might get away with just moving expansion tank and also a/c piping to accommodate this s/c, but when i do, end up deciding on any option, i will post a "FULL" how to and whats involved (both physical and cost (Australian Dollars) wise), most likey i will have to fully remove stock Rad shroud and fan and opt for 2x thermo fans on the front to compensate for the lack of wind tunnel affect from the shroud (where i live is very hot most of the year (tropical North Queensland, where the foam things around your beer keep them from going hot!)

how about i put it simply "Has anyone taken the pulley off of a Rotrex C30 style supercharger, and from what you have seen do you think an extension shaft drive (similar to the one i posted) can be used on it???????"

[123R-Prozak]

Sounds like your angry

***** your power steer off then

Don't need power steer on a straight line..

?? angry how do you pick that, if its about me trying to keep a forum on track, cause sick of reading many forums where someone asks a question and links 1 pic then forum turns into a trollfest of "no its this, or that, or your better off selling and getting a wrx" and if you read, im upgrading my faithful daily driver! if i wanted a drag car would get a v8! so removing p/s is not viable!

I can't answer your question but I think you are on the right track with mounting the Rotex on the gearbox side and running a shaft to it.

I'm sure and local machinist could fab something up for you to make it work. Often Rotex chargers are used on a extended drive shaft and I don't see them making a specific model for extended drive shafts so I'm sure you'll be able to remove the pulley and fit a shaft to it.

I'm sorry it was not my intention to detract from your topic with my Honda comment. Don't worry about some people around here, they can get a bit hot headed and insecure some times. we'll laugh it off

Look forward to seeing your Build, I was not much help this time but keep posting your questions and I'll try and help where I can, sometimes its a good idea to bounce ideas around.

yeah been chatting with Evo7 about certain things, plugging a few ideas at him as well, now the question is money!! as with all mods, gotta balance RL and fun stuff! hoping about 2 months(3maxx) ill purchase the unit from Bulletcars in Brisbane, then i'll go from there, by the look of it, too much stuffing around to do an extended shaft, most likely going to have to cut a hole in the bonnet, and place a backwards scoop on it, and have the s/c over the alternator! so i will update on this, when i get the unit and will post pics of every step of the way (have 4x8gig sd sticks for my camera!), so this thread maybe at a stand still for a couple of months, but after that it will be a mixture of + + + which will result in

get a new custom overflow tank made to sit out of the way, get new AC lines made and mount the charger between the AC compressor and alternator. I wouldn't mount the charger somewhere that would require bonnet mods.

Or just go turbo ;)

I've done both supercharged and turbocharged setups on the ZZE's and the turbo version is much better bang for buck.

well i have talked to a guy in England over his modded corolla T-sport with Rotrex, he had to move alternator to the back but his car had electric power steering, so there was a spare mounting spot with a small modified bracket to suit!, 2'nd there isn't enough room to fit it there, i have looked into other ideas, newest one, un-bolting alternator top blolt and rotating it down and having a bracket made to hold alternator and s/c, this would lower s/c engine bay height alot and not have it exposed as much through the bonnet, but this means the bracket may need to be stronger(don't quote me on this, i have no cad programs or anything like that to try and draw them up!) really don't want to mess too much with stuff inside the engine bay if i don't have to, but most likely expansion tank ins going to move!, a bonnet is easily replaced!, saw one at a wrecking yard for $40 no hinges, was tempted to buy it and cut hole, but no use until i have s/c for correct sizing, yeah i have measured things but rather see it!

on the last note, i don't like turbos, yeah i know with the right internals they are very strong, but alot of small cars around my area run turbos, cause their a dime a dozen, i'm always different, my old quote "You say tomato, i say FOOD FIGHT"

[CHA54]

I still think it would fit in that space with the mods I've suggested.

The turbo setup I did made an additional 30kw at the wheels over the supercharged setup, it did it with with less boost and more response... All on the same car wtih the same ECU etc etc

heres a pic from a T-sport in the uk, using the same s/c, note he moved the alternator to the back

see how tight it is without alternator, im pretty sure that distance between s/c and radiator would be illegal in QLD! he was lucky, his model has electric power steering, so firewall side has plenty of room and free mounting points to place alternator, but i really need to find time to take my car in and put it on a hoist, so i can get underneath and see how much room there is around and get some mates ideas about placement! but going to wait to do that till after i have the s/c, ecu and fuel system upgrades, which will be about 2 to 3 months time! , he also has a youtube video just look up rotrex corolla and its a grey colored one!

[onezzdashfe]

but the question is what sort of supercharger did you use and what size turbo did you use, cause with s/c's there is a big difference in how they produce their power!

[CHA54]

TRD supercharger and a standard secondhand WRX TD04L turbo. Charger at 11psi, turbo at 9psi. did 20,000km on the charger setup and now around 30,000km on the turbo.

The turbo setup is better in every aspect, lower heat, lower EGT's, more fuel economy, more power, more torque, gear based boost control for traction in lower gears, hardest thing is keeping it off boost :P

thats where the rotrex is different, it produces power differently to the trd roots style because its a centrifugal style, not trying to argue, but different s/c's do different things!, but i have looked at your threads, quite interesting, but how much did that vipec cost, i have tried looking around but only can find detail listings and no price, i was thinking for now of getting a Emanage blue, like what Evo7 is running, cause i don't think im up to using SA yet so a piggy back will do!

[SuperDave]

Did you not follow my link? That Celica is in Australia and includes all the information needed on mounting a rotrex to a zz engine. Probably go down a size from what he used for a 1zz.

[CHA54]

I'm quite familiar with the rotrex chargers, still wont be anywhere near as good as a nicely matched turbo. But I'm all for seeing another 1zz rotrex setup completed.

Vipec V44 is about $1600-$1700 retail from memory with 4bar map sensor, 2m loom and motorsport grade intake air temp sensor.

the problem there is how much engine room a celica has there compared to a corolla!

been trying to work out exact s/c i will need thinking going down one notch as you suggested C30-74, but going to have to put project on hold for a couple of months (2 at most if i can) to sort out some Real life stuff!

and where did you get the vipec from CHA54? cause for what it is that is pretty cheap!

hmmm thats interesting, you can use it as either piggy back or a stand alone from what i read up, talk about versatile, and i noticed on a few forum mentioning Ray Hall, i wonder if thats the same Ray Hall who has a turbo shop in Cairns where i live! from what i hear he is bloody good with forced induction systems, might go see him once i get my s/c and see how he recommends to set it up!
