Alternate Supercharging Options

[jeremyflower]

Gidday everyone,

I've tried asking the New Zealand club about this but haven't got any replies...

Has anyone here come across any cheaper options for supercharging an AS/IS200? I did a bit of my own research into various things and found that the 1G engine has a bit of a history and in the late 80's was fitted to a Toyota Crown with a supercharger fitted as standard (1G-GZE).

Does anyone know if this has been looked into in the UK? I was thinking that if a good supercharger and all the corresponding pipework could be obtained from a car wreckers it couls probably bolt up without too much drama (assuming it doesn't upset the computer too much and it all fits...) for a fraction of the cost of the TTE unit.

Also can anyone tell me what the model code of the TTE supercharger is? If it's the same as the one I'm talking about it'll add some strength to my arguement.

Specs are: SC14 85-89+ 1G-GZE length: 311mm/ width: 148mm/ height: 254mm/ weight: 11.9kg/ displacement: 1420cc

There should be a pic of it below (pic stolen from another site... sorry!!)

Any help would be great, looking forward to your replies.

Cheers,

Jeremy

I have thought about this route (i.e not a specific s/c for the car) i would imagine in theory that you could fit any S/C you wanted so long as it provided the amount of boost or more than a specific designed model and of course that it fits in the space you have.

I would imagine either way you are going to have to fit a piggyback fuel computer etc and get it remapped as the engine is going to be getting alot more air throughout the range at a higher pressure and fuel will have to be adjusted to suit.

As to using a toyota s/c if it comes from an earlier version of your engine i would jsut check to see what differences there are between the engines blocks get modified but its often how much so. Quite a few things stay in the same place

good luck

Hi, the TTE supercharger dont look like the one in your pic :o

[Rob]

AFAIK it is the eaton m65 unit, totally different to the one u have in the pic - that one has differnt mount points etc and also a clutch and it looks like lubrication pipes - the eaton is self contained.

you will have to make the piping, a cradle, get an intercooler, block the clutch, sort out the lubrication, find a piggyback ECU, sort out the bypass, find the correct pulley sizes for the boost etc - will prob cost more £££ and time than its worth

What I was hoping to do was get all the factory pipework off the 1G-GZE engine and modify it to suit.

Unsure whether there ever was an intercooler with this particular engine but I'll definitely be fitting one.

I was thinking that the clutch would be a bonus rather than a negative, the original operated on thottle position or manifold vacuum but if I can make it work with just a switch on the dash... do you see where I'm coming from? Instant power or ecomomy at the flick of a switch would be quite cool.

I've been told that I can pick up the supercharger itself here for $200-300, all the associated pipework and ancilliaries shouldn't be much more on top or that.

The ECU might pose a problem, unsure if the stock one will get confused by boost or not, guess it probably will though since it seems everyone going the forced induction route is going for the piggyback route.

Cheers for your help though, I'll keep everyone posted with my progress or any other information I pick up

:-D
