So I'm going to be building up a 3.4 PR, and from what I've seen the Trueleo is the only effective small-volume production bolt-on intake out of the bunch. The rest are un-documentd one-offs, or based off the 2.8 Fiero intake and are a joke.
Firstly, integrating the SFI/DIS from the 95 engine I'm buying into the intake manifold and block would probably be the best to base a performance build on no?
I know some members here must have done one-off intakes, what kind of experiences or results have come out of them so far? My needs here are for a bolt-on manifold that will efficiently flow the max that the 3.4 PR heads (even ported and matched etc.) will be able to support and possibly more CFM beyond that, seeing as I may do mild F/I as the money comes to me.
As I'm not reaaally a F/I buff yet I'm not sure if I'll need to just buy a new manifold when going turbo etc. but hopefully a skilly crafted one-off, or some production manifold that I don't know of yet will be able to fill both N/A and F/I roles??
What is the practical and efficient intake option here?
Moving along to exhaust...
Saying I go for a dual-plenum or tubular (IE trueleo style) intake manifold to un-cork the 3.4, I still want my engine to be able to exhale efficiently too, especially if I go mild F/I down the road.
From what I've seen the aftermarket header/manifold selection is pretty slim. My needs here are for a set of manifolds that will flow respectably for a N/A build as well as hopefully get away with supporting a turbo later on if that's possible. Durability would also be a plus here, that may be a matter of metal selection and heat coating/wraps etc. though.
What should I be considering? Are there any production manifolds on the market that can meet my needs or are customs my only real option?
Any real benefits of equal length primaries? What diameter pipe should I be using? What length of runners until they collect?
Any input is awesome, I'm hoping this thread can attract some attention from the iron head builders, as moving to aluminum heads begins to cause practicality problems for me involving the EFI/wiring.
Cheers,
