Liberty 3.0r-b 6spd manual mods?
 

Hey everyone.
I have had a H6 spec b for a while and was looking at beefing up the power, I was wondering if anyone here has had any experience with them or knows of someone that has.

There doesn't seem to be any places in Perth that have done anything on them except for an exhaust..

I have found this place over east that does a supercharger kit for them

Any thoughts or opinions will be greatly appreciated, except for the generic "you should have bought a STI" type comments.

Cheers peeps

3.0 spec B mods?
 

Hey peeps,
I have posted this in another forum also, I am unsure which is the right one as I am a noob to these forums.

Raptor Superchargers

Shame you didnt ask a few days ago, a guy on the liberty forums had a full raptor kit for sale. He still has a few exhaust parts left. A place over east called pulse racing have done a twin turbo kit. Not sure if its mass produced though. You could also get a custom single turbo built like the might car mods build.

Finally, since it sounds like you relatively close to stock, you could sell it and buy an Sti :P

Have you seen the Mighty Car Mods guys on youtube? They just finished a long-term project 11-sec car. Basically it was an old-school lib with a H6 transplant that they strapped a turbo onto. A lot of work cos they had to change over looms etc which you wouldn't have to do, but you would prob have to custom mount/dump pipe etc as I don't think there are any off the shelf options (could be wrong?)

Anyway, long story short, check out MCM for an idea of what they did mechanically, might help you out

Cheers man, yeah I have seen just about all of MCM videos, unfortunately I don't think there are any turbo yodas on this side of the country. Unfortunately my wife will not let me spend a huge amount of money (over 6-7k)... well to be honest she wont let me spend close to that, but I will have to talk her into it.

Welcome to the forums.

I have merged the two threads to keep all the comments in one place.

Do you have a full exhaust system already, extractors back?

When you get the supercharger, they will be required, so if you don't already have them then it might be a good idea to get them...while your saving for the forced induction.

Im a fan of what MCM did, but they have alot of friends and cheap labour. Getting a shop to do all the work could end up quite expensive. I havent looked into it much, but i assume there is no of the shelf turbo kit for these?

if not, i would lean towards the SC kit, raptor do have a good name in the SC industry so i would say there kits are quality units. the good thing about a SC kit is that you will get your NA predictable feel with liner boost levels...making it great for a daily / daily you can give a squirt of the line and beat most cars.

don't get me wrong i love turbo, but more so a fan of buying a kit designed specifically for your car. at least if it breaks you have someone to fall back on.

I thought they ran fairly high compression stock and performance gains were hard to achieve.

Thanks Unkn0wn, I have spoken to raptor, the throw in the the headers when you buy the SC kit, apparently a cat back system for a GT liberty fits with no problems and is only about 900 bucks. So that is not too much of a problem.

I have been looking around and there does not seem to be any turbo kits you can buy, I would prob have to do a custom kit which I think will be expensive.

Apparently the H6 is a tough motor and can take a bit. The SC should just be bolt on and go. I did provided a link in the original message to raptor. The only issue is tuning. It will have to be tuned because the SC with cause the motor to ping and lean out on the stock tune.

The kit looks like it has been designed for the car, which is good. The last thing I want to do is rebuild the motor because of putting too much boost into it.

Cheers for the help so far

Yeah that is what the dude from Stechnic was saying. He was open to the idea about the SC but he has not done one himself and wanted some more info about it.
I think even with an exhaust and headers you will not get too much power gain.. That's why I am considering a SC kit or something to that extent.

Thanks mate.

cheers for merging the threds

I remember looking into it when I had one and it just wasn't worth the effort as I was on a budget and gains were negligible.

Exhaust will net very little in the way of gains

Tune will get you some hp.

Better of selling, adding your 6k and getting a 03/4/5/6 sti

As I stated on the first post, those sort of comments are not helpful.

Thanks mate, that is where I got most of the info I already have on it. I was hoping someone in perth has done it. It does not seem so at the moment.

Cheers for your help

Not a lot you can do on a NA motor without opening it up.
Maybe a tune with a new chip, exhaust, but for the extra you get, maybe 10 to 15%, not good value - bang for your buck.

If ... the 3L H6 is a tough motor, and lacks low down torque somewhat,
it is a candidate for a SC.
You could expect up to 40% extra torque and 25% extra power, but my guess is you are up for about $12,000 or more for the job if all done by a workshop. Whoever does it should be listened to carefully w.r.t upgrading intake injectors and exhaust.
Who does that sort of thing in Perth? -
Try West Racing in Osborne Park, or, there was a SC place on the GE Highway Rivervale I talked to a few years ago, not sure if still there.

Yes they are because they are absolutely correct.

The 3.0RB is a cruiser, not a sports car.

You want it to go fast? Fork out and turbo/sc it, or don't bother.

A tune and exhaust combo would cost 2k and net you 15hp? Yay!

Enjoy it for what it is, not what it isn't.

Pick 2

The one above is also applicable for hookers, but not to be confused with the girlfriend model

Thanks for the help peeps. I will have to think about what to do next. Maybe just keep it a as a nice cruiser. It still goes reasonably hard for stock, so I cannot complain to much.

:)

They do sound glorious with a decent exhaust, very Porsche like.
