View Full Version : Kiwi MR-S project...

29-08-2008, 09:04
I know this forum is all about bigger engine swaps for the MR-S, but I thought you may be interested in a little race car project we are working on here in New Zealand.

Take one of these...


...strip it down...




Buy one of these as an engine donor...


Make a few cuts to make it all fit...


...fabricate up some engine, diff and suspension mounts...


...add some super lightweight fibreglass & carbon fibre panels...


...and hopefully end up with something that looks similar to this.
Turbo Hayabusa powered, hopefully around 450 hp, somewhere close to 600 kgs...and a whole heap of fun!

600Kg's? Fuck me, that will need to be seriously light weight fibreglass u got on there.

Nice project though.

sweeeeet :)

29-08-2008, 09:26
lovely project..now that is brutal..!!!! love it..:thumbsup:
how much do all your panels weigh..?

29-08-2008, 09:34
600kilos is helluva target and good luck on that one! will be awesoem project and I kno the busa engine well and big cc over here do turbo is up to the 600bhp mark for it and the guys near silverstone will superharge i with good results too. One thin I would say on the busa engine is go for the older ones as the new ones (ie late 07 onwards) are not good for tuning or forced induction and the older engine is the one to use. Cant wait to see the results of this as gonna do something new with the mini this autumn and wieght wil be on of the things to look at on it but not much left to lose/reduce apart from seats as nowt else left and only a few kilos to lose from the interior after the seats go. Only glass left is the windscreen fibeglass or cabon doors wont be huge saving over the guted standard doors which are now just skins so really scratching head to see what else can be reduced now.

Think if you get this down to 600kos will be an amazing machine as hat engine is very flexible when charged.

Jesus that's sweet

Two brutal.
Good luck on the 600Kgs weight target.

Don't know about this but, these guys http://www.powertecengineering.com/drive_solutions_home.php used to build my racing sidecar engines and they also produce the Radical sports cars. They have a solution to removing the chain aspect of your build, if thats an option you might desire. Although it would be added weight. Just some info for you.

I don't think you are aiming high enough :)
Go for the possible 700bhp you can get with the stage 2 kit :)

29-08-2008, 13:47
700bhp from a 1.3ltr lump is just a ticking time bomb and purely for drag racing I'd say. 400-450bhp would be plety in a 600kg car.

29-08-2008, 13:58
yeah but it would be fun.

Hayabusa engines are awesome tools, the abuse they can handle is immense. There are a few reliable 500hp ones floating about I just think 700 would be nuts.

Sort of glad I never bought the supercharged hayabusa I saw a while back, think the engine might have been removed to go in something else eventually :) That one had 257bhp at the rear wheel.

I'm looking forward to the end of this swap, is gonna sound nuts :)

What a creation, fabulous piece of kit. I can't wait to see vids of it in action.

fukin bangin. :thumbsup:

29-08-2008, 16:34
Now what you really want is 2 of those Busa engines and a welder and you'll pretty much have one of these:


Without the downforce unfortunately.

Would sound absolutely amazing though : http://www.youtube.com/watch?v=5YAFMZyBPI4

Amazing work! Wow... i'm stunned! What a project!

29-08-2008, 19:02
700bhp one s about a 10grand ticking time bomb

29-08-2008, 19:22
Holy shit that's epic!

nearly as subtle as the Caterham in Evo this month. Take 2 ZX12 engines, one supercharger an a carbon fibre bodied Caterham. 500kgs and 500hp.

fucking mental.

29-08-2008, 21:46
and I thought I was the only truly mad kiwi:D

guess not;)

Fellow Evo reader :)

It just looks mean as fuck doesn't it! Unbelievable PTW ratio. Yummm.

We believe (hope) that 600kg is achievable, remember that these only weigh around 1000kg totally standard. We have some fibreglass panels at this stage, but some will also initially be carbon and more once we have the body sorted.
To minimise weight we have (are) cut away all the unnecessary reinforcing including the sills, (which are very heavy & multi layered to make up for the lost strength in not having a roof) all the reinforcing around the windscreen A pillars, seat mounts, inner guards etc etc, even as far as cutting off the chassis rails at the shortest possible point past the suspension pickups...

700hp would be nice but we are after reliability, so are looking for 450ish. We have two engines and plan to build two complete rear subframes that house the engine, drivetrain etc so can easily swap the whole lot if we encounter a problem...or maybee a qualifying & race engine... :driving:


PS: Check out this link for a few pics of our previous projects (toys) including 2006 Ford Focus with Falcon XR6 Turbo engine, Supra twin turbo powered AE101 Corolla Levins, BMW Z3, Mustang Cobra RA, plus GT40 replica & convertible Falcon...

Excellent stuff, so what competition will you be racing in?

Where u based aswell, stateside? (am only assuming cos of the Falcon engine)

It's this sorta high end stuff we need as part of TB, alongside us homebuilders. :thumbsup:

Kiwi MR-S project...

Not sure if there maybe a slight clue in the title olie :hidesbehi

Also is the Flacon not used mainly in Oz and NZ rather than America? :hidesbehi

Olie you been on the source again? :hidesbehi

traditionally the falcon is an australian made car...but marketed in NZ Aus...and sometimes in south africa...

as we know...the big car companies market the same vehicle in different countries with different names....Holden monaro(AUS/NZ)/pontiac GTO(US) is one of the first that springs to mind at the moment

and if any other country is claiming the "kiwi" as their iconic critter....Ill kick em all in the teeth;)

Looks a bit like our Brit Car entry.

Not much visable progress on the project at this stage. Have the subframe that holds the engine etc, all made & mounted. It will also be used to mount the suspension pick-up points. The suspension points have been designed & drawn by a top race car engineer in NZ, so we are just making sure they are all 100% correct.
Recently had the car on the scales and bodyshell, engine, gearbox & "diff" weigh a total of just under 250kg, which is pretty much on track considering there is still some weight to come out of/off the shell itself...
