Six of New Zealand’s finest 4G63 bangers

7 September 2015

Mitsubishi Evos have a heritage in New Zealand that is so strong that the Aussies are thinking of claiming it as their own. We’ve been modifying the outstanding tri-diamond all-rounder since the old-school VR4 days, so it’s safe to say that we know our way around the 4G63 engine. NZ Performance Car decided to take a trip down memory lane, use up some gigabytes, and create our very own 4G63 throwback, with some of the coolest 4G63-powered vehicles we’ve featured in the last few years. If you’re here to find out information not relating to boosted 4G63s, leave now — you’ve been warned.

‘Quarter Master’

 

On the cover of Issue No. 199, we featured Michael Bradley’s 895kW (1200hp), 7.43-sec Evo VIII — a banger in any language. After owning a 671kW (900hp) Evo II for a number of years, Mike was sick of the regular breakages, something that a lot of all-wheel drive dragsters are well known for. So, after discussing his plans to build a tube-framed front with Top Gear AutoTech, he was convinced to build a rear-wheel drive monster that would end up running a 7.43-second pass at 286kph.

 

Built by Auckland-based Engine Reconditioners, the 4G63 block can handle in excess of 50psi of boost, thanks largely to its GT45, while revving up to 11,000rpm. To handle this punishment, the block has a set of custom-made methanol-specific pistons, custom rods, a billet crank, and L19 head studs. It has also been grout filled. The head was heavily ported before a set of custom drag-spec cams, titanium retainers, heavy-duty double-valve springs, and solid lifters were fitted.

The gearbox is a five-speed Liberty Equalizer equipped with a CO2 air-shift kit and a titanium bellhousing that houses the Quarter Master triple-plate clutch and custom-offset flywheel. The equalizer is a clutchless box that only requires the triple-clutch plate for staging the car, and not for changing gear.

Its Bogart Racing Wheels measure 15×4.5 inches up front, and 15×14.5 inches on the rear. They’re wrapped in Mickey Thompson’s 15×14.5×32-inch drag slicks, while the fronts are Mickey Thompson Front Runners.

Kat Benson’s time attack machine

 

“Diamonds are a girl’s best friend,” Kat told us when we featured her 2001 Evo VII in Issue No. 202, and it’s also the reason she’s stuck with one after deciding to upgrade from her early-generation Lancer GSR. She had big plans for her newly built Evo VII, but has recently focused her attention on NZ Superlap, where she has been extremely competitive. Here’s a snapshot of what the car looked like when it was first built.

Its 4G63 was already forged when Kat took possession of the car, though she still took it straight to Carl, Hans, and the team at E&H Motors, who quickly stripped it down and worked out what needed doing. The block runs HKS forged rods and pistons, and ARP rod bolts, while E&H has ported and polished the head, along with CNC cutting the valve seats and bowls. They then fitted HKS 272 camshafts, Kelford Beehive valve springs, A1 Technologies L19 head studs, and an HKS head gasket to round out the very sturdy engine package.

 

The Garrett GT3582R turbocharger, sitting on a Sinco manifold, runs a maximum of 32psi for this build. This gives Kat 400kW at the wheels, though she also has lower-power tunes for when full power is not required.

The Mitsubishi runs a fairly simple fuel system — a Walbro 255lph in-tank pump fills the surge tank in the boot with regular 98RON pump fuel, then a Bosch 044 external pump sends that fuel up to ID 1000 injectors sitting on a custom fuel rail up front.

The Evo that started it all for Michael Keen

Most of you will know Michael Keen from his latest build, which is one of the fastest street Evos in New Zealand — and it’s featured on the cover of Issue No. 216. But that’s not where Michael’s love affair for Mitsubishi started — for that, we wind the clock back to Issue No. 206, when we featured his Mitsubishi Evo IV.

With the IV continually dialling in upwards of 32psi, the block internals needed to be built tough. The bottom end is an STM big-boost special. JE forged pistons, Eagle rods, ACL race bearings, and ARP hardware can be found inside. The balance bar has been removed, and the entire rotating assembly balanced and digitally blueprinted. The head features a Kelford Cams port and polish, Kelford 272 cams, Kelford valve springs, and Ferrea 1mm oversized valves.

Sitting on the HKS stainless manifold is a Garrett GT35/40. When the original engine grenaded itself, the con rod slammed into the compressor housing, but thankfully Michael was able to repair it. He also replaced the exhaust housing with a smaller option to help reduce lag.

Making the switch to E85 required the fuel system to be upgraded. Fuel is now lifted from the tank to the surge tank by a Walbro 500hp pump,  before being fed to the ID2000 injectors via twin Bosch 044 main pumps. The fuel rail itself is a Hypertune item. The Evo IV features a 50-litre fuel tank as standard, which Michael used to to take 150km to empty while on low boost, and a wallet-killing 80km when the fun switch is on. With no E85 available on the pump, he used to have to buy it in drums.

To handle the power delivery there’s an HKS twin-plate clutch and flywheel combo, with an Evo V RS rear differential. Both the AYC and ABS driving aids have been binned.

Tastefully fast

 

Back in Issue No. 209 we took a look at Shannan Baker’s 400kW-plus at the wheels Mitsubishi Evo V streeter. Shannan originally purchased the Evo from a car yard, only to have it blow up on him a couple of months later thanks to a faulty wastegate actuator. The engine was replaced with a new one, and from there he set out to build a wild ride capable of tearing up both the track and the street.

Shannan’s 4G63 runs a Manley 100mm stroker crank, which pushes the displacement from 2000cc to 2300cc. The crank pushes Carillo rods and Wiseco pistons to create an ultra-strong base with which to make some serious power. Up top, a ported and polished Evo V cylinder head uses oversized valves, dual springs, titanium retainers, solid lifters, and a custom set of Kelford cams.

 

Shannan ordered a complete AMS 950R turbo kit from the States. The kit is ready-made for Evo fitment and consists of a 304 stainless steel thick-wall tubular manifold, Precision 6766 billet CEA ball-bearing turbocharger, TiAL 38mm external wastegate, and a stainless steel O2 housing with dual slip-fit recirculated wastegate dump — going fast made easy!

Shannan is a fan of upgrading, not just replacing, when things break — and his driveline is a perfect example of that. The factory gearbox remains, but it has been rebuilt with Evo VI GSR gear ratios and a taller 4.111 final-drive ratio. The clutch is a Quarter Master twin-plate, and power is fed out to a Cusco LSD up front, and Evo VI RS plate-type LSD in the rear.

Because Shannan runs both 98 and E85 fuel, the fuel system is a fairly intense affair. A Walbro 255 in-tank lifter pump feeds a 2.5-litre surge tank. Two Bosch 044 pumps then send the petrol up to some Fuel Injector Clinic 2150cc high-impedance injectors, sitting on an AMS fuel rail via stainless steel braided fuel lines.

Michael Keen hits us again

Only 10 issues after Michael Keen had his Evo IV featured in NZ Performance Car magazine, he hit us with the news that he had something else to show us, in time for Issue No. 216. Yes, you got it, another Evo. But this time an Evo IX, powered by an even more powerful 4G63 engine. If you remember reading the feature on Michael’s Evo IV, you’ll know that he has a thing for going fast — specifically in a straight line over the quarter mile. But as these things tend to go, although he was running lightning-quick 10.5-second quarters in his Evo IV, it still wasn’t rapid enough — Michael needed more. “I guess the bug had bit … You just want to keep going faster,” he said. He was already making over 450kW at the wheels while running one of STM’s excellent forged short-block packages. But with the sort of power he had in mind — somewhere around 750kW, or 1000hp — he was going to need a new drag-specific bottom end, as well as big upgrades to the IV’s set-up: the driveline, body, suspension, and tyres — it was going to be a big job.

After purchasing a 2005 Evo IX from Chris Rae — who was chasing the stock block record — STM set to work building something capable of Michael’s goals. This meant using the best gear available from Eagle, JE, Carillo, ACL, and ARP, which when combined with the best parts from both of Michael’s Evos would create an ultimate, nearly indestructible 2.0-litre four-cylinder Mitsubishi 4G63.

 

At 33psi the current set-up had nearly reached its limits, with STM’s tuner Chris Wall squeezing 525kW (704hp) at the wheels out of the 4G63 — spot on what Michael and the team at STM had wanted and predicted for the car’s testing phase.

After a season of testing, Michael will need to swap the huge Garrett T04Z in favour of something even bigger if he wants to knock on the door of 1000hp. But when he does upgrade, we’ll keep you posted on the numbers once it rolls off the dyno.

Ian’s first car

 

Yes, that’s right, this is Ian McKay’s first car, and he’s owned and modified it for over 15 years. What started as a bone-stock Mazda Familia GT-X has been transformed into a 606kW at the wheels 4G63-packing street weapon that runs 10s — making it a car we were glad to feature in Issue No. 215.

So, what does it take to produce 606kW at the wheels in a car such as Ian’s? Well, a very large-framed turbo helps, so Ian chose a Borgwarner S400SX, which is more than capable of pumping out over 40psi of boost, after the usually more-than-capable T70 turbo maxed out at 430KW. But what about the internals?

 

Ian’s 4G63 is now 2300cc after the installation of JE asymmetrical pistons, Oliver I-beam rods, a 100mm 4G69 crank, and ACL race bearings — all assembled by Dick at Hytech Engines. The head has been fully worked using a Kelford Cams 288-degree intake, and 290-degree camshafts with 1mm oversized valves and titanium retainers. It’s a good enough base engine to handle over 700kW should Ian want to, but for now it produces 606kW on 37psi of boost with Klotz 118-octane fuel.

Initially, Ian was only going to run a gearbox from an Evo, but then he thought, ‘why not use the engine too?’ We’re confident in saying the GT-X Familia wouldn’t be producing anywhere near as much power as it is now if he chose to run it with the factory engine set-up.

“I have thought about selling it, but it’s just not worth it. It’s just an expensive garage ornament, I have so much fun when I do these events, that I forget all about selling it. Who knows what will happen next now that this is done, I had thought about building a drifter but it’s sort of all been done. A nice cruiser, maybe a 13B turbo, but in something really different. I have always had the thinking that if you come up with something unique and it works, it’s just that much cooler. Sure it’s not the easy route, but that’s half the fun.”
