i been reading threads about aftermarket manis and stock manis and porting stock manis. its funny how the the sellers of aftermarket parts will always tell you that the stock mani is crap and they even think that even if your 4e is stock it should still have an uprated mani. i think toyota R&D department knows more than ur shop about manifolds. they been making engines since 1934. yes they are mass produced and cast with imperfections but the design is there that they spents tons of time and money R&D which you sir have not.
flowbench test a ported polished stock mani to any of the $400-500 aftermarket ones. the first things these sellers of aftermarket parts will tell you is that the stock mani will crack. if you take off too much metal u lose structural integrity. but then you can stregthen it up on the outside. and aftermarket manis crack all the time. and what are we told to do....weld it up. $600 for the same flow rate and it cracks just like the stock mani and you have to weld it up. you are probably gona heat wrap it anyways so it will just end up looking like a heat wrapped stock mani would
i just hate when people go around stating stuff as fact and saying the best option is to buy stuff from them.
heres some facts.
stock manifolds can flow just as good as the jam and any other aftermarket mani when its ported and polished...FACT
aftermarket manis crack just like stock ones do...FACT
stock manis cost 1/10 of the cost of a aftermarket mani...FACT
the only...and i mean the ONLY benefits from an aftermarket mani is its lighter than the stock one. but hey its shiny (oooooohhhh aaaawwww), you can brag about it to friends, "i have greddy fmic, sard bov, tong hybrid ct9, hks fuel rail, _____ MANIFOLD, blah blah blah", and it might even come with a cool sticker for you to put on your car.
i think if you have the money to spend then hey buy w.e makes u happy. but its just so stupid when some1 is told by a seller that they should buy an aftermarket mani when they are running stock boost levels or something like 0.8bar. these manis were R&D to hold up stock boost. so of course if your pushing 21 psi you should get a mild steel one.
idk just my thoughts. anyone have input?
