Turbo, piggy-back, and EG33 boost questions

Hello guys,

New guy to the SVX here. Not new to boosted cars though. I have a few questions after researching your forays into boosting the EG33.

1. Why don't you use piggy-backs? MAPECU2-4, SAFC/VPC combos?
These two we use on 2jz, 4g63, and Honda motors all the time.
Allows u to remove the MAF and run MAP system. NA or boosted
they work well and are easy to use with a good wideband.

2. Since knock is gonna be a problem if you raise boost to 8-10psi
why not use meth or water injection? Another mod we use very
well. Since winshield washer fluid is mostly meth...u can buy it
anywhere in a pinch.

3. Why not use one single mount rear turbo back where the cat is?
Easy install and you can do this yourself in a weekend with little
outlay of money. I know some will say lag is a problem...But us
Supra guys call lag a "head start" for the other guy !!! Plus you
get pretty decent gas mileage around town,and hardly any
welding involved. Hell...you can buy most of your hard piping
from CXRacing.com !!!

I have some STS turbos from my room mates 2010 Camaro I was
gonna try to mount with a SMIC from a Supra to try some of these
ideas on my $200 95 LSi I just got. Running at 5-7psi. Using a
SAFC/VPC and 440-550 injectors. With a Supra fuelpump. Stuff
I have laying around really.

The 95 has a rebuilt trans and only 150k just needs valve cover
gaskets and PCV valve.

Having boosted several NA cars in my life I don't see what the big problem
here is with getting a reliable 100whp out of the EG33.

Boost is boost. Nothing special to it if u follow the rules...

1. Don't get greedy
2. Keep those AFR's around 11.9-12.8
3. proper cooling. tranny,boost and oil.

Unless I'm missing something here? I'm not looking for a street terror. I can
hop in one of my Supras for that. Just feel this car needs another
80-100whp and those glorious turbo sounds to go with its awesome looks !!!
