hi there, ive just bought the xu10j2te engine and i was looking forward for a twin cam upgrade because ive already upgraded the standard turbo garrett t25 to a t25/t28 hybrid which means there will be alot of power increase therefore more fuel is needed so am i thinking right about the twin cam upgrade?? also i was looking for a sport exhaust and i found a greddy back box and here is the pic, so i dont know if the greddy exhaust the right choice for the turbo engine or not also i dont know if i need to change the standard middle box which is the standard 405 sri 2.0 8v xu10j2c??

twin cam upgrade? as in 16v head or what?

nope, does 16v cams differ?? i never did know

what do you mean by "twin cam" then?

You can't have twin cams without a head that'll take 2 cams...

I guess that's exactly what he's meaning, twin cam upgrade --> remove 8v head, put 16v head on.

Can use whatever XU 16v head you want really.

Need to fabricate new exhaust manifold unless you use S16/T16 head and standard T16 exhaust manifold.

exactly, so is the t16 exhaust manifold available in any peugeot parts store?? and how much does it cost and is there a site that sells t16 exhaust manifolds?? and guys tell me what u think about the greddy back box exhaust does suit the 2.0 8v turbo?? and does the standard xu10j2c middle box suit the new engine??? thnx in advance
