ok heres my plan: in about a years time i will have a bunch of money to spend. my goal as far as power is low 12's. with a streetported engine, using a standalone ECU (yet to be determined which one.) but my question right now is which turbo to use. the bnrsupercars stage 4 upgraded stock turbo with a 60-1 compressor seems like a good choice. heres what it says on the site
60-1 compressor wheel
· T04B package
· 360 thrust package
· Choice of turbine wheels (t3 hiflow, 0 trim, 69 trim, or P trim)
· Standard external wastegate flange added to your turbine housing ( external wastegate is additional)
· Ported turbine housing entrance

how much of a difference would a full turbo upgrade using the same compressor wheel make? in terms of HP at around 15psi? would it be worth the much higher price? and i dont know much about the turbine wheels... what is the difference between the options? and what size wastegate would i need to keep the boost under control?

i also have a question about wastegates. where does the exhaust go? back into the engine bay? i understand how they work, i've just never seen on in real life.

im just full of questions tonight

The full T04 will run more efficiently, and the engine will run cooler.

Probably close to 50bhp...

Yes, if you can afford it.

As a ule, run the biggest turbine trim you can afford - P-trim is the standard.

As a rule, run the biggest wastegate you can afford.&nbsp We normally run Tial 46mm or HKS 50mm race wastegates.


You can have them just channel to a "dump tube", which just pipes them under the car, or have the dump tube connected back into the exhaust.&nbsp The dump tube is rather loud when the wastegate starts opening - the piped-back-into-exhaust is quieter, but more work to fabricate.

thanks for the info! thats exactly what i needed!
but i will probbably still end up going with a hybrid because it would cost around $1000 more for a full upgrade (with manifold, DP, lines etc...) unless i end up with more money than i expected, i will probbably put that $1000 towards suspension.
