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?

+1 ... sub'd

500hp and a 45mm wastegate?
The welds look as if they were made by a blind man.

^ Couldn't of said it better myself.

For most renny builds after you spend all that money on boosting a Renesis you find out two things....

Your stuck at sub 300 hp and with a tricking time BOMB. :sad:




.

Yeah pretty much. An engine swap is the only way to go if you want to make more than 325HP reliably.

I'm sure you can 20b for less than 30k

I don't understand how this is so expensive, even the Hymee supercharger kit is $12300

I know Aussie wages are very good but these prices are just insane

I see the Rx8 forum bashing machine will enjoy this thread.

No bashing here Brettus, you know me, if there is an easy way to get power I'm keen!! As long as its not me doing the work its safe!, lol.
By the way....BBEEEEERRRRRR.

In Australia we cannot transplant a 20B for road use and you can only put a REW into a 2003 model. I am not sure how these guys will achieve 500HP at the wheels however, it will be interesting to see the results when they get there.

We have all seen similar claims before and they have turned out to be failures however, these guys have a good track record. I do understand that this power will be based on using E85 which is not really ideal for daily use due to the lack of bowsers that carry the fuel.

For boost rew absolutely easiest & cheapest way but we need reliable msp engine in my opinion if anybody manages reliable renesis i think the day of 8 pride is begining. How about mazdatrix hybrid msp now has anybody know the details of it ?

who cares where they land ultimately.... they've got a solid mission statement and the community will benefit from it.

LOL @ ANYONE that thinks the REW is the answer to a reliable booted 8. There is a reason the LSx swap is popular with the 7 community. l'm not banging on the REW either. I love that engine. Just saying it is not the solution for reliable boost.

I'd say an REW running 12PSI on a single turbo setup making 330 whp would be more reliable than a renny running 12 psi making 330whp.

Just a guess really...

Even if it is still does not make the REW reliable :)

Most of the problems the REW units show are either builder-related or tune-related. They can be fairly reliable at power levels the renesis can only dream about!

Yeah, I hate my REW swap! It's always breaking down :sad:





.

I'd say your pretty close shady, I made 363 @16.

I daily drive around town @ 12psi which is about in that 330 area.

Still enough to spin the tires in 3rd gear and scare the kids in the back seat :lol:

I'm not comparing the MSP to the REW. So everyone step back and put their daggers away.

LSX swaps for all!

My opinion is that a stock renesis block should only be boosted to around 7-8psi max . on a good tune . With some internal mods 12 psi could very well be reliable but so few of us have actually done the necessary mods it's hard to say for sure right now. I'll let you know in a few years :)

As far as 500whp being reliable - I'm just as skeptical as anyone I but live in hope ....

"Rocky and son Peter have just finished assembling the Renesis 13B engine for our 'Project 500' RX8.

Nothing too fancy inside, just some basic tidying of the ports and strengthening measures carried out in preparation for its boosted future...

Who else is hanging to see 'Project 500' hit the strip...?

-Pac Performance "

I envy people who can live the dream and share it with their children!

I saw one post at rx8club.au if everything as they write is true. Renesis Territory Begin..



RX8 Club Australia • View topic - PAC Performance Project 500

Just spoke to Rodney at PAC performance..

Pretty damn surprising!!

1. 500hp is actually at the rears not the flywheel!
2. Kit is completely compatibly with S2 8's
3. They are installing the kit on an auto 8 right now
4. They have tuned a haltech for an S2 GT in the past and are using haltech for this set up
5. The price is 30k, with full rebuild included in the price, rebuild is basically strengthening all internals, custom fabricated apex seals used in PAC race cars tailored for the 8, etc..
6. Kit has and is still being used in 3 cars to date, one being mazda motorsports targa 8, which has still had no problems.
7. Rodney says "I can pretty much guarantee, that as long as nothing stupid (i.e running on low oil) happens to the car, you won't have any problems.

500hp no way jose, not with that small of a turbo.

We've been making some solid progress on our ‘Project 500’ RX8 build, working on the car after hours and in-between the usual day-to-day jobs. As always, customer jobs come first and our own toys a close second…

http://www.pacperformance.com.au/Art...9f9585a8b7.jpg

Our fabricator Ross has now finished off the turbo mounting side of things including mounting of the Turbosmart 45mm Hyper Gate and fabricating a three inch dump pipe. Everything is tucked up nice and neat to ensure clearance is never an issue whilst still retaining ease of access.

http://www.pacperformance.com.au/Art...5c0d7d752c.jpg

With the Garrett turbo mounted in place Ross then moved onto the cooling and intake side of things, fabbing up alloy piping for the front mount intercooler. You can also see in this photo the start of the turbo air intake that will run into the standard air box.

http://www.pacperformance.com.au/Art...9d291ab35f.jpg

The intercooler itself is a chunky Pac Performance four inch bar and plate unit that will have no issues cooling the charged air. Mounted via custom brackets it sits in a V-Mount position to ensure no loss of flow through the radiator core.
To ensure there is ample flow through the intercooler ducting and baffles will me put in place to help guide fresh air through the core. This mounting style was used on the Mazda Australia Targa Tasmania cars with great results for both intake and water temps whether the cars were cruising or going flat out.

http://www.pacperformance.com.au/Art...8d61a1e875.jpg

The radiator is also upgraded as part of the package, with a quality alloy PWR unit taking place of the original core.


http://www.pacperformance.com.au/Art...915be705c9.jpg

Apart from a quick tidy up of the ports, new Pac Performance seals and extra dowels the engine as Mazda intended. Rather than go crazy with the engine itself the bulk of the power increase will come from the carefully-selected bolt-ons and of course the all-important tune via the Haltech PS2000 ECU.

http://www.pacperformance.com.au/Art...b5104e7205.jpg

Lastly we also received the Mazdaspeed front bar that’s part of the package and will be fitted to ‘Project 500’. On top of the much cleaner and meaner look it will give the car it also offers increased air flow to the entire cooling system.

Nice fab work, what are you doing for and engine mount? That's not a Mazdaspeed front bumper, BTW. It would be sad to see a shop in the industry using knock off parts.
