I've been getting quite a number of emails and messages lately asking what's happening with the build as there wasn't any update ever since my last post.
I'm sorry folks, I was busy with work and haven't had time to update the blog.
Couple of things has happened since my last update, the first engine which has been built with the CP forged pistons and Crower billet rods was sold to a friend of mine and is currently undergoing transplant into his car.
He will be running the built bottom with his existing turbo kit but with a Haltech Sport 1000 replacing his E-Manage. Once the car is done I will have it featured here.
Secondly, we're revising our setup again. Yes, AGAIN.
Toby has decided to make some last minute changes to the engine configuration, mainly the pistons and turbo.
I can't reveal much at the moment, but we're aiming to make at least 400 wheel horsepower so we're revising the engine compression ratio and the turbo as well.
Stay tuned.
JUN Auto Releases High Lift Camshafts for Toyota 1NZ-FE
(Source: JUN Auto)
The link to their news release can be found here.
Though JUN mentioned that the camshafts can be used with the stock ECU, but that is only for the Toyota Vitz (NCP13) owners.
For other models you would still need to use an engine management for optimum results.
The current model released by JUN is the street specifications of 252 duration with 9.0mm lift.
If you are interested in getting a more aggressive profile such as the 256/272 duration with 9.0mm/9.5mm/10.5mm lift, you will still need to get in touch with GT Auto as they are the only people carrying them at the moment.
Stage 2 Turbo Project - Crankshaft Nitriding & Journal Polishing
Most stock OEM steel crankshafts have been induction hardened, which is actually a low cost process in which the surface is heated by a high frequency alternating magnetic field that generates heat in the crank's surface quickly before being quenched.
Because of the uneven heating and cooling due to cost saving reasons, the crankshaft hardening process creates a lot of stress within the crankshaft. While it is an ideal hardening process for stock applications, but it is really less then favorable for high performance/racing applications.
Hence, we had the stock 1NZ-FE crankshaft sent overseas to be nitride coated and its now back and ready for us to assemble it along with the engine rebuild. Nitriding is a chemical hardening process in which the part is heated in a furnace, the oxygen is vacuumed out, and nitrogen is introduced which penetrates the entire surface.
The result? An extremely hard surface which will give us a peace of mind when we increase the rev cut to well over 8,000+ RPM, allowing us to stay at the redline level without any worries even under hard boost.
If you're wondering what was the material used, its titanium aluminium carbon which gives the black surface you are seeing in the pictures. Read more about it here.

The color of the crank is now different
A closer look will give you a dark bluish purple look
We also took this opportunity to have the crankshaft journals micro polished, a process where the surfaces are made clean and smooth so that it reduces the friction, allowing the rods to spin a lot more easier and faster.
The end result? A high revving friendly engine to go along with the other parts :)
Surface of the journals are now clean and smooth

Stage 2 Turbo Project - Golden Eagle Intake Manifold
Christmas just got better with the arrival of the intake manifold from Golden Eagle Manufacturing.
Thanks to GT Auto, as Golden Eagle's authorized dealer they've worked together to developed this intake manifold for my car.
This is still a prototype.
The design of this intake manifold is not final yet as we'll be testing it and to keep refining the design until we get it right.
So I guess you won't find this intake manifold up for sale anywhere yet but if you're the adventurous type and would like to give it a try please do get in touch with us.
Or if you're interested in getting one when its ready, you could get in touch with GT Auto to place an early pre-order and get a discount off the list price when its up for sale!
And to copycats out there, imitation is the sincerest form of flattery.

We're quite impressed with the quality of the finishing

The flange is made for the 60mm throttle body that we'll be using later
Stage 2 Turbo Project - Golden Eagle Head Gaskets
Now that we're using the 77mm over sized pistons from Ross Racing along with the newly sleeved engine block, we also got Golden Eagle to custom make these head gaskets for us as well.
They are multi-layered and is 1mm in thickness, just as we requested.
And Golden Eagle were kind enough to even threw in 2 steel tags for us as souvenirs!
