as the 1uz firing order is the same as a SBC the 2 middle exhausts on one side swap to go with the front and rear on the other side my plan as i have a rear sump is to put a group of 4 pipes together under the front part of the sump to allow the pipes to cross over.And i will use a x balance tube to raise the pitch of the exhaust note. an x also gives a few more HP than a straight across balance tube.
Ok, here's another question. What about cams for an engine with 180-degree headers? Do they use the same cams that regular headers use? Based on the articles that I've read (based on the links posted and some of my own research, and you can correct me if I'm wrong), regularly cammed V8s use a lot of duration to help extract the air out of a engine that revs high. Those cams happen to also have a lot of overlap, which helps in creating the lopey idle. Would you be able to reduce the overlap on an engine that has 180 headers and still be able to evacuate the same amount of air? Or do I have the wrong idea?
custom stuff would include
1 cranck, 4 cams, injection and ignition system from motec probably, 8 titianium rods (pauter maybe), 8 pistons, and an enormous bunch of very High grade very light bolts to keep everthing in place,
or call KMS (kronenburg motor sport) in holland and ask them about their batch bought Audi/Lamborghini V10 engines. there's one going into an ultima as we speak.
would be brilliant effort to engineer a flatplane set for a 1uzfe though... Errol (RMS) made some sort of assumption that he would be able to pull that sort of stuff off..... so if you have silly money to spend, maybe contact him?
rev the crap out of it, with a good microfone at hand, tape it and let us hear!
