Our little 2JZ "engine that could" is coming right along.  Just an intake pipe and a couple of small engine dress-up details are all that's left!

Project Supra MKIV: Part 8 – Fuel and Engine Breather Systems

No plans to skimp on this 2JZ now!

by Pablo Mazlumian

If you’ve been following Project Supra, you’re probably wondering when we'll fire this engine up already.  With so many parts changed, this build not only takes a great deal of time, patience, and wife’s hard-earned money, but diligence is required to get everything featured as well. 

Add to that a momentary, yet rather large setback in November when my laptop fell carrying four unrecoverable articles-worth of pictures (my bad), and you can see how easy the weeks can build like cottage cheese, and before you know it we don’t fit into the same jeans anymore. 

We thank you for patience and interest thus far, and trust us when we say we’re almost there.  The car will be running very soon, but let us share some key components we've added, and why.

Today we’ll be discussing our fuel system, starting with our Walbro pumps that you see here nestled inside a PowerHouse Racing fuel pump hanger.

As important as the fuel pumps are the fuel injectors.  We’ll talk about why we chose FIC injectors.

PowerHouse Racing makes a few Supra-specific engine dress-up parts that also serve a function.  We’ll start by showing you their engine breather kit…

...as well as PHR’s Deluxe power steering reservoir relocation kit.

How do you feel about working in the Supra's engine bay? Obviously you have a lot of parts that are quite a bit larger than stock but it seems that the bay isnt all that cramped compared to many other cars I have worked on. Not sure if you had any major parts deleted or moved.

Are you running an electric fan or the stock belt-driven one?

It's curious that you are so anal about heat-wrapping your manifolds, then you turn around and paint a radiant heat-shield BLACK of all colours... Black actually /absorbs/ heat and makes the heat shield /less/ effective than just raw aluminum.

I may be wrong here, but I am pretty sure that the white black vs white heat absorption argument (heat reflectivity is more correct) is in regard to how much of the color spectrum the color reflects. White reflecting almost all colors, black reflecting almost none. I don't think it has quite the same implications for something under the hood experiencing radiant heat as something sitting in the sun with ultraviolet and stuff going on.

Besides, Swain coats specific parts that need to extract heat quickly (i.e. intercoolers) black.

Thanks for reading, y'all!
@Protodad: If you look at a stock engine bay, you'll see it's way more convoluted and cramped: http://mkiv.com/techarticles/spark_plugs/engine.jpg
Also, @Monkius, yes there shouldn't be issue with the shield being powder-coated black. It's to reflect the heat upwards anyway, and out of the louver that is already on the back of the hood.
@Dusty, yes electric fans that will be featured in next installment. I definitely like the look without the shroud on there, although some may prefer it.

nice car! im woundering so if that motor has a non hydraulic set of lifters how often do you have to adjust the valves? and have you fired it up yet?

@theneil: thank you. I think you would have to have the valve adjustment checked at around 60k, and then if all is well you shouldn't need to touch them again unless you drop in new cams and such.
The car has been fired up, yes! Sounds good, and all it needs is tuning and a new battery we are waiting on :).

Haha, no all is well. Have had the car for a few weeks running on the wastegate spring and it feels good. Expecting to go in for the E85 tune soon but the shop has recently gotten swamped. I will have an update within the next few weeks however. Car spools up quicker and sounds better than ever. Will have video and dyno graphs soon. Thanks for checking!
