I was thinking this too... Looks amazing I love every detail but I think your primaries will prove too long and risk flattening your power curve at higher rpm. Have a look at 7oxins experiences with his 7ag build.
What length are the primaries? I love your fabrication skills btw, so i dont mean to be too negative.
If it were me, Id use the talent you obviously have to make a custom inlet manifold that gets the inlet to the left side of the motor, away from your big primaries.
Have similar height issues with the 2azfe conversion, however I was lucky that the stock sump works perfectly and can be removed in car.
I also dont like the idea of crossmember spacers, mainly because I want to run it low and I dont want to have my lcas pointing upwards and create all kinds of bump steer.
Im looking at an a9x type scoop to get the bonnet clearance up where it needs to be.
Almost finished my hilux diff, mounts are on I just have to redrill the axles to 4 stud:
I will be making a heat shield for the intake and probably boxing off the pod filter. As for the extractors they are 31" long (each within half an inch) which is what most of the aftermarket ones are, but they were 1 5/8" and I made mine 1 3/4" so it should be alright. I thought about doing the intake,but the forward facing TB's dont usually distribute the air evenly. This is fine if the engine is boosted but being NA the standard one does the job very well.
Thanks for all the comments and praise guys

lol @ flattening a power curve in a 3RZ-FE...
This isn't a 4AG
So physics doesn't apply in a 3rz fe? Please explain?
Diff looks awesome! Big centre!
Uhh, low revving high torque 2.7l square bore narrow angle truck motor vs high revving wide angle twin cam 1.6
have you ever SEEN the power curve of a 3RZ-FE? I drive one every day of the week...
You still havent explained anything about the passage of gasses through the exhaust. No rational reasoning, no evidence to back up your rude comments. I'm inclined to think you dont know what you are talking about. I could be like you and string a bunch of engine related words together, but then I wouldn't make sense either.
Hey Lappy Id really like to see the collector on those headers.
Matt I don't think he was trying to be rude. What he is saying is that the engine is made for stacks of lower down power and it's going into a light weight car. Therefore the no matter what extractor design it's going to pull from anywhere in the rev range regardless.

Well, the 2.7 litre engine at 5000 rpm will be volumetrically similar to the 1600 at 7000. So it may well relate more than you might think at first examination.
I'm just trying to instigate a technical discussion, and examine Lappys' reasoning in the hope that I may learn something. I guess I have learned that this is only the place for sarcasm and insults, not to learn anything. Its my fault, I expected Nick to engage in something other than putting shit on people.
Lappy, what kind of exhaust headers do the 3rz engines come with, are they factory 4-1 or 4-2-1 and what sort of primary length do they use? What have you designed your headers to do? I assume gas velocity will be increased by the smaller pipe size? Did you use a nice merge collector and what size pipe do you plan on running after it? Are you using a megaphone type arrangement or a straight pipe? Catalytic converter? Resonator?
