Why A 4G63 Is BETTER Than An RB26 | R32 GTR 4 Banger

Pulling out a RB26 and replacing it with a 4G63 is not something you see to often, or possibly ever, when it comes to the R32 GTR Skyline chassis, but that is exactly what has been done to this time attack weapon. Let's see what makes it tick.

Dom from Tony Rigoli Performance (TRP) runs us through some of the reasons why Chris Alexanders CJA Motorsport Nissan R32 GTR Skyline is better off with a 4 cylinder Mitsubishi 4g63 producing 1030hp to the hubs via a Borg Warner EFR 9280 is better than the equivalent 6 cylinder RB26.
The 4g63 retains the MIVEC setup in this application which along with a custom cam helps the car have great boost response from as low as 4,500rpm with engine management and traction control strategies being managed by an EMtron KV16 and a MoTeC Dash/Logger handing the rest including extra data logging along with a MoTeC PDM.
Like many cars we see now the factory strut towers are retained as per World Time Attack Challenge (WTAC) rules along with the firewall which is one reason why the team have chosen to go with a 4 cylinder engine which gives them great packaging advantages especially when coupled with a transaxle in the rear of the car.
'Fire ring' cylinder sealing is used to keep cylinder pressures where they should be, and how that works along with a copper gasket is explained by Dom along with why a 2.2L 4g63 build using a TRP stroker kit was chosen over a 2.4L option.
Not bad for a build that took a few weeks eh! We're sure there is plenty to dial in and look forward to seeing this build progress up the time sheets in the coming time attack events after a few battles with the aero at this event.

[@pacpacpacpacpac]

I had an R32 and an R33 GTR many years...now an Evo 9. All I can say that the 4g63 is the better engine in every way...better response, lighter, no oil issues, not to expensive for more power and other things.

[@AdmissionGaming]

I thought the heads had some oil issues isn't that why they get noisy lifters? I remember reading it on a tuning website.

[@HHCHunterYTC]

@@AdmissionGaming Yeah, par for the course with a hydraulic lifter setup. But it's really not common. I've had mine for a long time and I haven't got lifter tick yet.

[@slow26gtr]

Worth all the bs just for the sound though mate!

[@skylinefever]

At some point, better hydraulic lash adjusters were introduced, and they solved the noise. The Evo IX may have had them. Using current HLAs in earlier Mitsubishi engines often cures the noise for a long time. Also, Kiggly racing has an oil regulator that helps the HLAs function correctly. Jafromobile mentioned that there is an oil feed in the cylinder head that gets smaller when you resurface it. Therefore, when rebuilding a head, port it open to prevent problems. I aspire to own an Evo X. I hate timing belts with a passion. Just because some cars I love have them doesn't change that fact. Also, the Evo X will now and forever remain a classic because Mitsubishi probably won't build another rally car.

[@robbalinski1606]

[@joels6736]

I want to do the opposite of this swap. I have a Eclipse GSX laying around with a built 4g63 but it's automatic (hate auto) and the dsm manual transmissions are trash. I want to take a full r34 AWD Attessa drivetrain with the 6 speed and fit it into the GSX chassis (fully seam welded) and get it to bolt up to the 4g63. From what I can tell it should work after getting the oil pan / front diff figured out, and a few other details. It would dramatically alter the weight balance by rotating the engine 90 degrees and getting that heavy automatic out of the engine bay and going with a long shaped tranny down the trans tunnel instead. Ideally the goal would be a 50/50 balanced 2700-2800 lb Attessa AWD Gsx but it'd probably more like 52/48.

There are various advantages and disadvantages. The reason I love inline sixes is because they have no need for balance shafts. To me, a balance shaft is like a constant drag that only exists because the engine is flawed from the beginning. This is a reason I passionately hate 90 degree V6 engines. The 4G63 uses balance shafts. EDIT: I deleted the comment about the 3SGTE Supra because other people mentioned it. Toyota did it for the same reason this man created an inline 4 GT-R.

Over a 1000bhp to just the rear wheels seems like it gonna be a handful even with the ECU based traction control. He did mentioned the gearbox is somewhat similar to the R35 gearbox but why he didnt choose to run a second prop shaft to the front and have a front diff for AWD traction? The iconic Tom's Supra also runs a 4 banger 3S-GTE in the race car instead of the 2JZ for weight balance. Thats a weird but interesting suspension setup there. Why they didnt go full on push rod and go that weird double cantilever hybrid sort of suspension?

[@jcadlols]

You get pretty diminishing returns out of awd at higher speed with a lot of downforce. These tyres are also pretty overworked so anything to reduce tyre loading is going to pay off even more than in other categories. I love awd but the context I love it is a low speeds or in bad weather.

[@linchester8464]

@@jcadlols Pretty sure the Motec/Haltech and other latest ECU have some sort of AWD traction control which can be made more rear biased. The Skyline ATTESA while old school by today standards was quite an interesting piece of hardware. Under hard acceleration, its only RWD. Only under cornering will the torque split to the front. Now there are gearbox control unit or GCU for short which controls the clutch / gearbox and diff systems. I am pretty sure we can make a solid AWD that is a monster both on dry and wet conditions.

Yeah they're not just driving this to a carpark to bounce it off the limiter trying to drop some guys boxer shorts. It could sound like a wet fart and it wouldn't matter on the performance side of things - Taz.

Why so much Honda hate, K-series one of the best NA engines ever, nevermind 4 banger

[@hpa101]

He was just kidding 😉 He also doesn't hate the RB26, he's set a world record with one - Taz.

[@hondamanvtec2894]

Just K swap

[@VincentViolence]

Why not just use a GTS r32? Waste of a GTR much?!

[@hpa101]

Who cares? Someone bought a car and is doing what they want with it 😎 - Taz.

[@BlagoP]

They're both mediocre engines.

[@Paper.Power.Politics]

Way to go is. 2.0/2.3 built focus ST ecoboost engine! With the 2.3 internals! Proven to be the new 4g63

[@EVOFans]

Oh you mean the engine that can't flow for shit beyond 6000RPM without extensive headwork? No thank you, 4G63 master race

[@Paper.Power.Politics]

@@EVOFans well that’s why u have to use a 4 port head buddy!! Not the stock head! It’s not even the stock block! But still all ecoboost! I’m building a 1000whp ecoboost mustang right now! Using a sleeved 2.0 focus ST block , and a 4 port head that comes on the Range Rover evoque. Should be out by end of the year! Or early next year

[@dsm_zo]

The 4g63 will make way more n for half the cost. No sleeving the block needed cause it's still closed deck cast iron, heads ports flow plenty b4 porting, will rev with the best of them with proper valve train. And also has a bunch of years of development over the ecoboost engine. 4g63 is king of 4 cyls but people wanna forget n hop on the k bandwagon.

[@Paper.Power.Politics]

@@dsm_zo yeah your 100% right!! But hard to find a good evo nowadays.. I’m building a 1000whp mustang ecoboost right now, but not using the stock engine components! Using a sleeved 2.0 focus ST block, with the 2.3 internals, 4 port head off Range Rover evoque for more air flow, it’s a variant of the ecoboost engine. Everything is the best metals and parts money can buy! Like Callie’s 4340 enforcer rods, upgraded 3.5 rod bolts, 250wall h13 wrist pin, custom spec vct piper cams , with a custom turbo kit by ETS with xona 105-69s turbo. Should definitely give evos a run for their money. But yeah would be a lot easier to make that power with a evo. But when it comes to cost it’s pretty close

4G63T the best 4cylinder
