As many of you may be aware the Haltech R35 GTR Skyline had a catastrophic blow up on Friday the 24th if October. Our GTR has been running on a new platform of Haltech engine management flawlessly for over 5000km's now.

The car was being track tested at Eastern Creek raceway

(http://www.eastern-creek-raceway.com/) when the engine let go. The car had completed countless flat out laps with the engine producing 400kw at the wheels, up from 300kw at the wheels - The driver tells me it was a terrific ride!

After finishing Haltech's latest Flat shifting calibrations a few more test laps had to be carried out. With no sign of trouble the car went out and successfully completed 2 more laps before finishing up on the side of the track leaving a trail of oil and plume of smoke behind it.

It was time to put it in the trailer and go back to the workshop to pull it down. After building up enough courage our in-house mechanic removed the VR38DETT from the car and set it up on the engine stand.

A few hours later the engine was fully stripped and the damage to the engine was clear - It appears Haltech have found the limits of Nissans new super car!

The engine had met its maker.

Piston #1 and #3 had separated from their lower halves right through the center of the gudgeon pin. As the Conrod's had no piston's to guide them up and down the bore they started smashing the bore, block, oil pump, sump and anything else that got in their way.

Due to the massive damage to the block we will need to replace it. And figure it's a great time to make the engine a little stronger. We will be boring the motor out and installing Darton sleeves, replacing the factory cast pistons with a study Forged unit as well as installing a set of Billet conrods. This should allow the engine to reliably produce over 400Kw at the wheels and handle the pressure.

Keep an eye on the Haltech website or drop us an email anytime for further updates.

this is how the R&D works.

Drive it and upgrade it slowly until it let's go.

Once it lets go, research the causes and weaknesses, and built a package that will ultimately make the identified sections stronger, and allow much more power and upgrades to occur.

Once you have this package in, tested and showing potential you start selling the package, and perform the original process all over again.

As you get more and more performance mods, you add to stage 1's package until the engine blows up again.

Now you have the upper limit of stage 1, and the supporting aftermarket mods for it.

Once you rebuild the second motor, you have the base line for stage 2 under way, and you keep upgrading until you blow the motor again, and you again have the stage 2 kit, the supporting mods, and the upper limit all sussed out.

Blowing cars up? :D

Just kidding. 400AWkW is quite astounding if the only thing changed was the ECU. So does that mean the car could have reliable and comfortably ran 350AWkW by changing just teh ecu without many dramas?

I have been waiting for this also. Will be interesting to see if other failures result from the same thing.

Also interested to see how much all new gear will cost to strengthen it for the next round of abuse

Hmm should chuck a 2J in there, 400rwkw on stock internals wouldn't be a problem then :P

j/k

like someone said, good time for some R&D and gives them a chance for a good footing in the modification of R35s.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Should have asked what is the car?

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.
