I currently
have a Greddy Turbo kit on my 94 Honda civic Coupe which cames with a Sohc
vtec Motor that is 1.6 4 cylinder. I was looking to upgrade the Turbo to another
turbo with internal wastegate, that would not need the replacement of Manifold,
maybe even keep the stock downpipe, But that I could deal with. I even went the
extra mile and called Greddy themselves but there was no help there. What I had in
mind was to Upgrade from my TD40H-15G to there Twin cam Kit which is
TD05H-18G. My problem is that the 15g is not efficient after 6000 rpm, its like it
dies off and My car Rev limiter kicks in at 7900 rpm. I want something that makes
power all the way to redline, I also want something that when I want to push more
then 15 psi, it is efficient also. I have posted before and Search and got nothing. Any help would be appreciated.

 

Why not just buy a t04/t3 hibrid from http://www.majesticturbo.com or http://www.turbonetics.com. I'm not sure why you prefer the internal wg(emissions?noise?) but all you need to do is to just change the piping before the I/C(if you have one), get a Tial 35mm, and get a new dp.

 

My problem is that I dont want to change my Manifold, I just want something I can bolt on, I dont have any problems with emission in NYC and Noise doesnt bother me.
