s/charging a supra

Guys,
I'm on the brink of deciding whether to go ahead or not and need some advice.. I own a 2jz-ge JZA80 supra with a full 2.5" mandrel bent exhaust, and pod filter, and i'm thinking of putting on an SC14 charger. Worth it? I'm not after MASSIVE power, just a bit of balls down low rpm.
Now, I'll be running the charger on stock boost (4psi?), with an FMIC setup with the possibility of changing to a smaller pulley (more boost) later on. Will my A/C need to be taken off? I think so?. What power can I expect? Will I need a piggy back computer for more boost? fuel reg? What will be needed to put it on? How do you adjust when the s/c comes in (rpm)? Anyone want to estimate costs?
I will also be running run an in-cabin switch to allow ON/OFF mode. Suggestions?

have you thought about using a sprintex supercharger? although I don't know if they make a kit for the 2j.
The sc14 s/c would be a bit small, wouldn't it? - seeing as how it is off a 2 ltr motor (I used to own a 1ggze with the sc14)..
just a thought ..

Unless you are greatly attached to the car I would suggest selling it and buying something with the power you are after. The changeover price will probably be less than the cost of modifying properly...

you're going to disconnect your air-con for 4 psi of boost?
not something I would even be considering.
the FMIC will not be all that helpful when you're only running 4psi (they're much more effective at higher psi)
personally I wouldn't really bother... what sort of a budget were you looking at?

budget of $2000 ... I think this can easily be done
- charger
- mounting brackets, belt
- cooler, piping
anything else? i already have a pod filter
I will run whatever stock boost is for a while.. I'd prefer to run 8 or 9psi, so always possible to upgrade later on. I didn't buy a TT supra because it would of cost me another $10k for a decent one. For that amount, I can do a turbo conversion on my current supra and get 500hp.

yep -
how are you going to control the SC ?
what are you doing about fuel injection?
what are you doing about maintaining the right fuel ratios?
what are you doing about cooling intake air?
what are you going to do about an intake?
how are you going to go from the s/c to the throttle?

Everything is going to be left stock, thats how this guy did it. He had no issues on that boost level. Running a piggy back system is only necessary for bigger boost. Stock fuel pump/injectors are fine to handle the stock level. I'll leave the rest up to my mechanic

To answer your question: no, it's not worth it. A budget turbo installation could be done for less money and be much more effective. The SC14 is just too small for a 2JZ, and making it fit (with all the associated plumbing issues) would be a nightmare.

REAL NA mods are exxy and nowhere near as rewarding as forced induction.
Sure, he could spend 2 grand on bolt on rubbish, but the power gains would be minimal/non existant.
Real gains will require opening the engine. Goodbye $2000 really quickly.

the cheapest way to do it would be to find a wrecked 2jz-gte supra, or someone who's just upgraded the turbo on their 2jz, and get the factory manifold & turbos

what would be the maximum costs?
for everything... fully fitted.
actually I would prefer a GTE swap...
but i don't think i can find a mechanic in brissy that could do it.
even if i could, i would think the cost of labor would be tremendous...

Nope. Don't do that. The GE and GTE exhaust port spacing and exhaust stud patterns are totally different. They just don't bolt on.
You're looking at a totally custom setup.
I strongly suggest you go to www.supraforums.com and surf around the NA section. Plenty of folk have done it. Kits are available from the US.

freakysoarer, the cost is massive.. just adding to your list
- air filter
- map sensors?
- aftermarket ecu? optional i guess
- fuel regulator
by the way.. i got quoted JUST for a nice exhaust manifold, approx $1000... turbo, you're looking at $1500+ for a brand new T04e or something. And thats only 2 parts!!
to import a turbo kit $7000.. then allow fitting

Best and cheapest way to power up is "NOS"

NOS is illegal on the streets. If you get caught using a bottle, expect a MASSIVE fine ($10,000) and a possibly a jail sentence.

not just that but also any of the equipment used facilitating the use of NOS
on the other hand i know 5 ppl who use it on the street and they've never been caught, thanks to some tricky piping and bottle placement
and its not that big of a fine, its usually just them ordering oyu off the road and you have to get an engineer to inspect tht you dont have NOS anymore... not to denote how serious it is when you get caught with nos but - they will make sure you dont have a car for about 3 months, they just keep bombarding you with paperwork

So if I were to import a kit from the US... say, from FMAX...
it would be like about US$5500 plus fitting...
and the option to do a GTE swap... whats the full cost?
And what would be the reliable of the 2, in terms of normal street usage?
And are there any experienced(as in the GTE swap) mechanics out there that would settle evrything for you for a price?

if you were to import a kit from F-MAX, the final cost would be above $7000-$7500 (I just used a currency convertor).
GTE swap... finding a decent 2JZ-GTE will set you back a shitload. You would have to change the gearbox as well, and also fuel system.
normal street usage on both, they would be fine

Toyomoto also do a kit, and DaveH (from Supraforums) is about to release a budget kit - might be worth investigating.
