Hi Guys,
Just thought i'd start a little WIP for my MR2 as i'm building a new cylinder head to finish off the motor.
As the title suggests, it's a '95 Bathurst ed. MR2. I purchased it in 2006, so i've had it a few years now, but still lovin it every day.
 
It's been run in the NSW hillclimb series (2009) which it won the class with, it was good fun racing at the different venues, bathurst in particular was a blast.
 
Currently i'm rebuilding a whole new power package for it, as when it ran the hillclimb series it had a rebuilt bottom end from a gen3 turbo swap, as well as a set of semislicks.
So pretty much everything is getting tickled with some real nice toys now, and hopefully will be done with that for next year so i can run the Aust. hillclimb series.
 
A few pics of it at grafton before the modlist, taken from one of the other competitors with a nice TME EVO.

As far as current mods go there is a bit,
Powertrain
 Gen3 3s-gte motor has been swapped in, with ct20 turbo
 - Forged o/s pistons with ceramic coating
 - Gapless piston rings
 - Forged rods
 - Modified the standard crankshaft (now a lot lighter)
 - 3" exhaust downpipe
 - custom 3" exhaust
 - custom intake
 - boost controller (at 18psi)
 - larger sidemount intercooler
E153 Gearbox and standard LSD
 - exedy 'hyper' clutch
 
The handling was not forgotten either
 - Tein Mono Flex coilovers
 - whiteline adjustable swaybars
 - Dunlop semi slicks (205 front, 225 rear)

At the moment though there is an absolute bucketload going into the new cylinder head and accessories that have been looking more and more daunting as the parts have arrived, The cylinder head is currently down at the engine builders, now that all the parts have been cryo treated, once I get some flow numbers from the porting then the rest of the parts can be finished up.
In Progress
Cylinder head rebuild and blueprinting
Reshaping of ports
Reshaping of chambers
1mm o/s valves, modified further to reduce weight and improve flow
Jun Valve guides
lightweight valve springs
undersize titanium valve retainers
shimless valve buckets
274 degree high lift billet camshafts
adjustable cam-gears
ARP head Studs
 
Also a new fuel system:
Surge Tank
External fuel pump (bosch 044)
ATS top-feed fuel rail
2000cc ID Injectors (flowchart for mine had 2200cc )
Sard FPR
Wolf V500 EMS
 
A new Intake System:
Phenolic Intake Spacer
Custom Intake manifold
90mm Throttle body
Water/Air Intercooler
Water Injection
 
A new exhaust system:
Custom exhaust manifold
Twin 38mm wastegates
3.5" downpipe
lightweight 3.5" exhaust
 
The exact turbo is yet to be decided, but the astute reader might noticed a lack of BOV on the mod list as to what family of turbo i will be getting.
James might be able to guess that one :P
 

Very nice weapon you got there, love the action shots - that's how MR2s are made to be driven!
Enjoy. :)

Borg Warner ftw. Looks like a pretty decent build. Could you PM me a price on the cylinder head parts and approx costs for labour please? I'm not quite as far along as you are with the build - I'm just slowly acquiring parts here and there for mine.
 
Would look alot better with the stock rear lights IMO.

I would also guess Borg Warner EFR....
 
I just recieved a 6758 in the mail this week 

Yea, i'm just waiting for some flow figures from the head but going off some flowmaps i have i think it'll be the EFR 8374, i asked for fullrace to put my name on one as there seems to be a short supply of these EFR critters.

Great to see another MR2 out there on the competitive scene. Do you have footage of the Grafton track?
 
Best of luck

Very nice list of mods keep up the good work will be good to se it up and running when it's finished

Hi All
Been waaaayyyy too long since i've been on here... But I'm sure you guys will be very interested in the MR2 now...
 
So after quietly accumulating parts and getting defected a month before getting the car to the workshop (located 600k's away from where I got defected... another story for another time...) I got to work on the MR2 and it's looking rather special now as we move into the tuning stages I might split this up into 2 posts cuz theres alot haha.
 
OK, What's been done? well what hasn't?
 
The cylinder head was the first part to be tackled:
Gen3 3sgte head (blueprinted and components cryotreated)
 - Shimless Buckets out of 2zz
 - Jun undersized titanium Retainers
 - Jun Valve Guides
 - 1mm OS Intake valves
 - GSC Beehive Valve springs
 - Brian Crower S3 Cams
 - Adjustable Cam Gears
 - Porting work to the intake/exhaust
 - ARP Studs
 
I originally wasn't going to touch the bottom end... then we took the head off and saw slight wear on the bore... enough of an excuse as needed to strip and rebuild the bottom end as well... the owner of the workshop believed mark was due to improper cleaning of the bore from a previous rebuild... it passed the white rag test when I was done with it...
 
The Bolt on's list sounds nice, looks nice, smells nice..
 - Borg Warner EFR8374... and the 3 year wait that went with it when I was informed the american indy car teams got them in precedence to me who had pre-paid for it... thankfully the aussie dollar was really good back then.
 - Custom made twin-scroll exhaust
 - Custom made tapered intake manifold
 - Custom Air/Water Intercooler
 - Custom pipework... much pain to be had here as you will see
 - After-market radiator
 
Fuel System upgraded to handle pretty much any power i ask of it now... the ID's I got max out at 3700cc's... It was fun making it idle, so made the choice to run it exclusively on E85, and running 17.5 volts to the injectors to get the idle nice... it's very nice now idles like a stocker haha.
 - Top Feed Fuel Rail
 - ID 2000cc injectors
 - Sard FPR
 - 2.5L Surge tank
 - Bosch 044 external pump
 - Replaced all hoses with biofuel compatible ones save the in tank pump... will be changing that in short order I think.
 
Oil System was modified as a... preventative maintenance measure... now an oil cooler where the intercooler would usually be found... the thermo fan there for backup. On a separate note the exhaust manifold necessitated the requirement to make a custom dipstick... what a pain that was...
 
Also replaced the CV's with the ATS racing ones... gotta pull them apart as I think we did them wrong as evidenced by the "clunk clunk" when turning left when any amount of load is applied... straight line however is fine so dyno testing was able to be done.
 
I previously mentioned I had the wolf V500... Wolf were nice enough to upgrade me to the V550 when I found out they brought it out. We haven't done it yet but gonna put a clutch switch in and set up launch control and anti-lag and ignition cut on it... can't wait to see that working, bring on the quick shifting haha.
 
Anyway the build was pretty straight forward save a few choice things like forgetting to prime the oil pump and having to make up a dipstick tube and signal noise
 
With all that said and done we got it running and have starting the tuning process and after a few runs it was putting out over 600nm of torque on 16psi... still got a bit to do yet tuning wise haha! gotta get cams dialled in and then finish the break in before we go into the scary 20's and 30's
 
Anyway piccies coming up next :)
