Could you please explain in more detail how can you match cam profile to exhaust manifold style as I dont have the book?

Great design! What sort of program did you use to draw that up?

Thanks for your replies people - its is already becoming more clear... But what does 304 and 321 stand for in materials? What is standard wall thickness for street NA and turbo manifolds? Would 16 ton pipe bender be enough to bend mild/stainless steel and inconel? PS and no I am not planning on using titanium

Any tips or tricks to this - I am having real trouble with polishing in between and inside letter (like inside "o" etc)?

Will both the stainless steel and mild steel be suitable? What are the other chatracteristics that I should consider when purcahsing tubing for fabrication of custom exhaust manifold? Are the same materials used for turbo exhaust manifolds manufacture as the manifolds for NA cars?

Any more pics... I would have imagined tha more people here have custom/aftermarket manifolds?

Just curious what exhaust manifold people are using, so post up your pics... Interested in manifolds for all engines - just wanna see different designs... :)

Well I read somewhere that a standard 240z has a weight distribution of 51:49 - almost perfect. Now consider a 240z with an sr20det in it - being a 4 cylinder (will seart completely behind the front axle) and having an all alloy design (meaning its lighter) it will alter the weight distribution significantly and from what I can see this alteration will make the car rear heavy, which in turn will lead to fun but not a very efficient handling dynamics on the racetrack.... On the other hand I keep hearing that 240Zs with SRs have great handling, could someone please explain to me how that works? While I understand that its possible to cancel some of the rear-heavy effect through proper suspemsion setup, wouldnt it still be better to have close to 50:50 weight destribution?

Got any pics of them on the car? And what flares are you panning on using?

Any one have pictures of that car? I really want to see how the te37 looked on a Z.

^^^Yeah I heard those cranks are expensive - but still thought I will give it a try - you never know what you might find in the wrecking yards... I am actually planning to go down the turborcharged path as well and was thinking about usinf the ld28t exhaust manifold. I am sure it will provide great low down torque, but I am slightly concerned its high RPM flow capabilities - has anyone used those manifolds succesfully? Btw did maximas come out with both ld28 turbo and non-turbo? Were all the patrols with ld28 turbocharged? What exhaust manifold are you planning on using Dennis? What about you Dave - what manifold did you use? John.

I know they were used in 80s patrols but could someone specify the exact time period? Any other cars it was used in? Thank you in advance.
