Stainless Manifold?

[Stagea1]

hey can anyone please explain the pros and cons of having a stainless turbo manifold? im currently deciding what to go for on my Stagea

[pipster11]

a cheap one will not hold in the heat so it will not spool as well

a cheap one will also have crap runner lengths and collectors = less flow again

a cheap one will also crack easily

the stock one is fine up to 300rwkw

Sweet thanks mate. I didn't think they were good anyway

plenty of people run them with not much problem. You may need to get the faces machined down for peace of mind more than anything - but other than that, the only other real issue with them is if you're hanging a big turbo off it, especially high mount - you might want to reinforce it with some additional bracing as some have cracked in the joins under severe heat.

other consideration you need to make is if you want to redo the cooler piping/front pipe or not - because the aftermarket manifold will most likely move the location of the turbo.

if it's just to fix the problem of a damaged stock one, just get a stock one - spend the extra money on getting it cleaned up inside professionally. as has been said, stock ones support plenty of power - but keep in mind, these are a piece of cast steel, mass produced at lowest possible cost to get the job done using the least amount of materials and taking up

if you're doing turbo, new lines, doing your cooler etc then i'd do go aftermarket - quality will vary with price to a certain point - but if you want a good option at not huge cost check out the 6boost manifolds.

otherwise, has been said - stick with what nissan thought best.

there is also a gibson motorsport one for sale on the forums that i saw. made for an RB20 but fit up to RB25's no worries.

if you haven't heard one of these things in real life you're missing out..... s3x for your hearing. still remember the first time i heard a car pull away, not even on full boost, with one of these on..... never heard a turbo car sound the same, it sounded like an exotic supercar.
