124,000km Service

 

It's time for a service again but this time round, it's a lot more hurtful to the wallet. Besides the obligatory Torco SR1 10W-40 and a Nissan oil filter (Part No. 15208-53J00), I got the HKS GT-RS turbine rebuilt as well. It well sort of uhm ..... blew up. 

So it was removed and sent to an authorized Garrett distributor to be looked into. A new Garrett CHRA GT2871R was ordered and in it went into the HKS GT-RS housing. That certainly put a huge dent on my wallet but at least it's now as good as new, literally. 

With my new Tommy Kaira Digital Meter Cluster, the mileage now actually reads 108,000km. Will be using this reading from my onwards.

The inevitable has come! The ER34 needs a new turbine to power it's heart.

I've always told myself to modify the stock Garrett TE27 turbine to a ball bearing unit and replace the fragile ceramic fins to stainless steel versions. That is a slightly cheaper alternative yet provides just enough additional juice to keep me happy.

I've been waiting for that day to come for quite a while because I knew one fine day, I'm gonna blow the ceramic fins of the stock turbine. Amazingly though, it withstood all my punishments todate. Or perhaps I don't push her hard enough?!?

I dunno about that, but what I do know is that, finally I have in my hands something better than just modifying the stock turbine. Yes sir, I've got the HKS GT-RS turbine ready to bolt onto the ER34's RB25DET NEO! Woohoo!!!

Pic 2: On a WGNC34, the GT-RS netted 395ps and 463.8Nm of torque :O

HKS GT-RS ball bearing turbo upgrades are bolt-on turbo upgrade kits for the RB engines. These are designed to bolt directly on to the stock manifold. Together with Garrett, HKS designed and sized the turbine for maximum power and response throughout the RPM band. The GT-RS turbine is rated at a very usable 400ps! *grins*

The one I have has a T25 flange thus I've got to change the exhaust housing to a T3 flange in order to bolt on to the manifold of the ER34. Other than that I've also got to fabricate new stainless steel braided oil lines. And then we are good to go!

I've heard, read and also test driven an ER34 with the GT-RS and the response on this turbine is nothing short of superb! I can't wait to get this baby into the ER34 and start making a little bit more ponies. Yeah boy, the ER34 project is starting to get just a little bit on the serious side in the engine bay.
