turbo ???
hey guys, i was just about to start making my reverse y-pipe for my turbo but i couldnt decide what piping size to go with...what size did you go with from bank 1 and bank 2 to the collector then to the turbo?? i will probably go with a t3/t4 turbo...not to sure what brand....also what size intercooler piping to go with?? i see some people run 2.5'' and some run 3''...what whould you suggest???
my set is (parts that i already have):
stock internals vq30de in a 95 fed spec maxima 5 speed
mevi intake manifold
act 6 puck clutch
definitive crank pulley
greddy emanage ultimate
ngk wideband
tial 38mm wastegate
tial 50mm bov
still looking for a turbo, and a intercooler and piping...
debating on if i need head studs or not
my goals will be the most whp i can make with a stock vq30 without blowing the motor...
anything i need to upgrade or anything that you would suggest??
lmk
thanks

You left injectors off your list of things you still need. You WILL require injectors for this. I would also HIGHLY recommend a reliable methanol injection setup. If you want to push the limits, it is one of the most effective ways to keep your motor together.
Anyways, IC piping - 2.5 is more than sufficient for 450whp which is about as high as you're probably going to want to push a VQ30 (and 450whp will require a tune that is on the money).
Forget reverse Y. Reverse Y setups are old school. Extra piping means more lag, worse performance, and more weight. Do a forward Y. It's pretty well mapped out how to fit a Forward Y these days.
Forget a UDP. UDPs are a complete liability and provide virtually zero gain. 1-2hp at most, and that 1-2 hp comes at the risk of ruining your engine, an engine which you have already stated you want to push to it's limit. You'd be absolutely out of your mind to put a UDP on this setup.
What turbo you get depends on a lot of factors, need more info on your intended use of the car and what your requirements are as far as lag and response goes, etc. Also your budget and personal preferences.
Personally, I'd probably get a Master Power brand turbo if I were buying a brand new these days. You can also piece together a good turbo if you're willing to search out individual parts or have one rebuilt for a few hundred bucks. Lastly there's always Holsets.

lol the funny thing is your probably right because 1500 is pretty damn close to idle.. As for the OP, 500whp is too high of a goal. Wait and get the car boosted first then possibly add meth later but not right away. Also figure out what size turbo you want to run. Put it this way, a garrett gt30 would be too small for the motor. A gt35 is a good starting point
