what kinda power if any can be gained from switching to a tubular manifold over the stock one still using the stock T25 ? thanks in advance.

 

It depends on the manifold. i've seen approximatly 10 to the wheels, sometimes no gain, sometimes there's the possibility of more than that.

take this Full-Race unit, for example:

Available through us, there is a possibility that it could make 20 due to its' awesome collector.

 

If you're trying to get more power (more than 250ish) from a T25, then you're beating a dead horse. If you're going to buy a $1200 manifold, you should probably save another $1200 and put a decent turbo on it.

 

i was looking at the megan racing manifold on your website, and that what i was thinking of, either that or the fever racing one......

 

the fever racing one is just a top speed.
save your money.

 

what if its a t28bb?

 

still high hopes for a ball bearing t28.
t3/t4 probably better.

 

GT28XX series turbo + Full Race bottom mount = the best sounding best horsepower bottom mount solution that will not melt your brake master cylinder nor have downpipe fabrication issues

 

There is a customer of ours that made 267whp on a t25 with the upgraded intake and exhaust manifold
