N/A Supercharger Project x2

Rally said:
No need for engineering as far as I know. The rear calipers were available on the RA version of the STI, and I am still using the original 4 pots. The brake lines are approved. The gearbox uses the existing mounts. If I put a 2.5 litre engine in it I would have to get that engineered.

But upgrading of the turbo to give more power is virtually the same as getting more power from an N/A. Im keeping the same engine just increasing the power.

I have been reading and read somewhere if your producing less than 15% of power than the most powerful engine that came stock with that model you don't need to get it engineered, just a permit from the Department of Transport...
Looking into it more though and going to send a few emails...

I won't even be producing as much power as a Forester GT :shrug:

Thats upgrading an existing turbo, not adding a S/C.

That's a good point, will be interesting to hear what they say.
 
That's why I did not want to comment- I am not sure what the WA rules are
 
I'd forget the 4 pot brakes unless you want to change wheels, I've got a set of early WRX 2 pot brakes with shoes & discs you or anyone can grab for $100, much stronger than single pot brakes.

When I had mine engineered he didn't even want to drive it, just looked at the lift mods and passed it, I wouldn't bother telling them either, my Liberty is still regoed as a 2.2 auto after 6 years of having a good double the power and it's already been written off lol.
 
Forgot about the wheel thing. Yes, you need WRX rims to fit the 4 pots- but you can get a set of those 16" WRX rims for about $100 these days.

Yes it will be interesting indeed to see what they have to say :)

What about the H6 Forester guys??

That orginally had a stock 2.0l n/a. Now currently has a 3.0l H6 pushing over 220Kw and still has the stock brakes and 15" rims.

Wonder if it is engineered? Dulagarl?
 
Indeed. Once again it would depend on the state rego laws. or perhaps it was engineered.
 
Agreed- if that is the case it is indeed a worry. I'd imagine an engineer would require a brake upgrade- I'd like to think he would anyway, even if the owner did not. It's worse when you get blokes sticking big block V8's into Escorts and Gemini's and think that by putting VT Commodore twin piston front calipers on will be enough. I'm generalising here, not referring to a particular car.

It's all engineered, as is Venom's H6 liberty - needed it for rego since they both moved interstate. Lift and engines are covered ;) AFAIK the foz is still on stock brakes, but it could have beefier brakes installed... Greg will tell you ;)

I'd say your brakes will be fine, it's torque you're after, not the fast paced boost of a turbo that you're after - just don't drive it like a turbo!

Cheers

Bennie is as usual correct.

Don't think it puts out 220kw though taza, unless you know something I don't. More like 186 kw stock, but having said that it does have a very generous exhaust and is tuned "hot", so it might be as much as 200kw. I'll know next time I put it on a 4 wheel dyno.

Still has standard brakes afaik. Would like to change that one day, but I'm busy saving it from the insurers atm.

Oh ok, I read on ozfoz over 220 with the tune up and aftermarket exhaust... :lildevil:
But thats still pretty darn good then anyway!

Do you know anything about what was invloved in getting it engineered when you bought it? Does it have a modifications plate under the hood?

By thw Way hows it going with the hail damage? Getting it all sorted I hope :raspberry:

link? You could be right.

Dunno what was involved in getting it engineered. Doesn't have a plate afaik, but engine number is noted on rego papers.

Hail damage? still in the process of getting quotes etc.
 
Just write R134a on the supercharger and pretend its the A/C.

Seriously though the dpi guys are pretty decent especially if you take the right steps before you do the work. They have a list of engineers they recommend.

I have a mate building a rotary Gemini and he's going through the process atm. I'll find out the specifics for you if your interested.

If you do go the sneaky route, it might be better going for 3rd party only that way they won't be as likely to inspect your car, you'll save money on insurance and you stand a reasonable chance of not going bankrupt if you rearend an exotic.

I will see if I can refind the link.

Hope you get the hail damage fixed soon. Was the interior damaged at all, wet?

Yeah that would be great, i would like to take the right route rather than having issues with licencing and insurance. Or atleast find out whats involved.

That cable you mentioned for the locker project in the other thread too would be great.

Ordering the chargers tomorrow and they will be posted Friday, should be here Monday or Tuesday with express postage.

The project has to be done by next Friday too so will only have a few days to do it. Thank god for Australia Day, can use the day to work on it then and hopefully ahve them up and running the same day. Looks like im going to have a few late nights out in the shed with Dave trying to get these done before next friday :raspberry:

Taza
 
Wow Taza, I'd suggest you take your time on this project, it's not something you want to screw up! And to do two of them in that time - insane!

Cheers

Bennie
 
Good luck mate.

Just wondering about the whole switchable thing. Will the s/c cause a restriction in the intake when it's not running?

Apparently not - it's a very good all rounder once setup properly.

Also Taza, just remembered, forget the BOV that vents to the atmosphere, go for a setup similar to the factory one - this is where the BOV vents around the SC14 so the air is effectively just cycling so no boost is being produced. It won't mess with your ECU either.

If you've spoken to Subarino about it in depth you'll know that he hooked up two BOV's to sort out the boost while off throttle issue.

You'll work it out.

Cheers
