Does anyone have anything useful to say about this relatively cheap HKS 2.8 kit that appeared late last year?

the one that can use stock conrods if you wish.

"step zero" I think it is called, and a stock redline of 8000

as far as I know the price is about 400,000 yen. Which is $5k. Plus $? for install.

Anyone know what the $? usually comes to..

In addition to increased displacement effect of 2.8L, STEP ZERO is the best solution for engines that require better response.

The target maximum revolution is best for stock or GT-SS turbine with greatly improved response.

The affordable price allows usage just for engine overhauling.

It is optimized for target turbines and rpm.

Although it is full counter, the ultra lightweight design achieves quicker response than ordinary STEP1 or STEP2.

Full counter design decreases load on metals.

The pitch of both connecting rod ends is not changed as ordinary kits and stroke is adjusted by piston height.

This design is less side pressure, less friction and more durable than other manufacturers' 2.8L stroker kits that change the pitch between the both ends.

・Newly designed φ86.5 piston.

Piston bore can be selected depending on engine block condition between φ86.5 and φ87.0.

・Proven MADE IN JAPAN (HKS in-house production).

Couldn't tell you an exact price but I assume it would be no more then the HKS Step 1 / Step 2 kit.

Tangomatt has a HKS 2.8lt kit in his R34 GTR, best ask him and he can let you know whats involved and pricing.

His HKS 2.8lt was put together / tuned by Ben from Racepace.

Well your RB26 will become a lot more responsive and the revs will just blast straight up, no sweat.

Will have plenty of pull too!

Pure 'sleeper' mod and will surprise a lot of ppl.

You thinking about doing a 2.8lt conversion?

What's your goal?

Its just basic kit that is purely for response while using GT-SS turbo's or alike. You'll get around the 400ps (dont know what that is in HP or Kw's) but I'll be at HKS on the weekend so can get more info.

I saw them a few months back and asked about them and they reckoned it was just upgrade kit for more performance, lighter crank and revs more quickly but 8000 rpm max. I'm pretty sure its not a forged crank, just lightweight counter.

They made them up here because everybody is broke and doesnt have the coin for the Step 1,2 and 3 kits !!

400 PS = 394.52 HP

400 PS = 294.20 kW

Sounds good your heading to HKS on the weekend.

Please do tell us how you go.

400ps is roughly 293kw... which I assume u mean at all 4 wheels?

I would have thought that is pretty conservative estimate with GT-SS turbo's and supporting mods..... let alone adding the 2.8 kit??

Dont quote me on that figure as gospel as when I was talking to my mate at HKS about the 2.8 build on my car at the time and was wondering why they were so cheap compared to the Step 2 kits.

There's a few configurations on the kit with the basic starting at 400,000yen.

Why only 400ps?

considering the standard GTR crank and rods can see almost 600ps then it must be the piston design holding this kit back? maybe they are light cast items similar to stock not forged

that or the crank is significantly lighter (and therefore weaker) than the standard crank?

Ok my mistake !!

Was just on the blower to my mate at HKS and Max power rating of kit is 600PS !!

sorry for the misinformation.

Crank is full Counter weight only.

Forged pistons and Rods.

Use of N1 Oil pump is fine as limited to 8000rpm but you cant be too carefull so upgrade of oil pump is up to customer.

Highly responsive motor with great torque !!

600 PS = 441.30 kW

That sounds more like it :P

Good to hear that elrodeo666.

I love a great responsive RB26 as the experience is pure awesome!

The Japanese rate it at the wheels but their dynos are notoriously number happy.

Regardless its pretty good bang for buck.

My 2.8 Step 2 build here was bloody expensive !!

So is it a lightened factory crank by the sound of it?

If so - that would be quite a nice saving.

I would say the RPM/power limit would be relating to things like rod bolt choice and so on, which are easily solved

Just bumping an old thread instead of starting a new one.

Is anyone using the step zero kit?

It says that it will suit someone running GT-SS or stock turbos and only revving to 8000rpm. Is this HKS under rating their product or is it really that weak?

I would be interested to know if it would be capable of around 600hp with a T04Z and 8500rpm with ARP bolts all round and all the good necessary hardware.

Thanks

I am looking at 2.8 options myself at the moment, and a tuner responsible for the engines in some of the fastest time attack cars in Japan tells me they are using the Step Zero in the majority of their cars, all of which are producing at least 650PS and have yet to find the limits of the kit - Interesting feedback

It appears the Pistons and Rods included in the Step Zero are the same as those included in the Step 1, leaving the main difference as the crank

    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
    • Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.
    • I also got the same floor mats for a bit of extra bazzaz haha
    • Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
