Stage 4 Pac Performance Low Mount Turbo Package
 

PAC PERFORMANCE 'PROJECT 500' RX8

http://www.pacperformance.com.au/Art...bf53071292.jpg

For some time now Pac Performance has been revered for building some of the countries toughest rotary street cars. After years of R&D we believe we have created combinations and packages that deliver the three main ingredients that we consider essential for this kind of application; Power, Response & Reliability.

The Pac Performance ‘Project 500’ RX8 is an in-house build being developed to showcase our Stage 4 upgrade package for the Mazda RX8. This is the ultimate power package upgrade for your RX8, transforming it from a mild-mannered cruiser to an exotic killer whilst still retaining a stock-like appearance, drivability and reliability. Drive in, drive out.

The Pac Performance Stage 4 upgrade is the same package as used on the Mazda Australia Targa Tasmania cars and includes a full engine rebuild with upgraded seals, extra doweling and turbo porting.

Helping the 13B Renesis engine do its thing will be a custom Pac Performance-spec'd Garrett turbo built specifically for this application; mounted on a custom-built steam pipe manifold. In an effort to retain a factory appearance under the hood, keep the manifold and exhaust design simple and very importantly, maintain the cars great balance, the turbo setup has been mounted nice and low.

This positioning necessitated some clearancing to be done on the factory cross member which is carried out by our in-house fabricator Ross.

Although a large amount of material is removed, it is replaced with much thicker steel plating and substantial re-enforcing and bracing will be carried out, making the modified cross member much stronger than the original.

Every aspect of this kit has been thoroughly researched with a lot of effort being put into strengthening, clearance and ease of access; aspects that other manufacturers often miss-prioritise or even overlook completely when developing so-called bolt-on ‘kits’.

They claim 500hp at the wheels.

Looks like a lot of fabrication anyone have a idea of cost?

$30 000 AUD for the full package that includes an engine rebuild. It is a drive in drive out service

The reason it is called the 500 project as the power output at the wheels will be 500hp. It is also S2 compatible.

So if you have deep pockets then this will be the ultimate RX8

Wow.

Well PAC does have a reputation of building quite some fast rotaries... In fact they hold the highest trap speed record for a rotary.

I wonder how reliable is this ? Esmeril made a project like isn't it unreliable ? Are they know how about SP turbo Rx-8 ? What's the details of these power figures reliability or trick is e85 ?

Yes there guys have a good reputation so they will give it a good shake.

Will be interesting to see more details

Has anybody know the details of sp turbo rx-8 ?

Ric shaw owns one but has not revealed any details.

Here is some info: Mazda RX-8 SP for Targa Tasmania | CarAdvice

Ric shaw had purchased one and did it up and was on sale for around $60k. I think it has sold. He also has a brand new engine with strengthened internals currently for sale.

Interesting exhaust manifold on Pac's kit.

I am curious what they are doing for an engine mount on the turbo side. If they hit 500HP it will be for 10 minutes.

That manifold equals for better flow i think, after porting big pipe diameter and flow better for boosting quicker and better.

Has anyone tell me how many kilometers reliable turbo Rx-8 goes ? Totally engine life after FI ?

Depends on the turbo and the boost you run...

49,000 kilometers I'd say is the average.

Also it will be running on E85...

As a second note it doesn't say 500 whp or bhp anywhere on the page

So I am assuming its 500 hp on the engine dyno

Which would equal 410ish whp after an 18% drivetrian loss...

410 on E85 seems more believable.

On the aus forum we have been told 500hp atw, and our dynos generally read lower than yours over there.

Damn, this is something right here.

It's $14500nz ( $12200au ) for a drive in drive out 400+ REW swap ( inc fresh engine ) at RX7Heaven and that has plenty more power potential

I don't see how this Renny upgrade is worth it when you can REW swap for so much less

That makes me almost want to break my engine!!!!

will follow with much interest ..............

It's what I'm gonna do, not even gonna fuck around with boosting the renny unless i get a great deal on a turbo kit.

Next engine will be a REW for sure, that'll be ages since my engine is 10000km old lol

After playing in Brettus' one the more power thing could be addictive!!!!!!!

The setup does look awesome and it's a rebuild of the engine which is very cool .. that being said I'm in agreement with you.
Not in the least which should also be mentioned is all the bitching and moaning you hear over people being told to expect 10k USD just for a descent FI setup.
Can you imagine the wailing over 30k?
