 I get it... this is just a joke.  You're trying to sound as ignorant as possible just to get us wound up?

Yeah if a Honda 1.8 can spool a big truck motor turbo around 4k to  
20psi+ than idk. The hx35 and he351cw both out spool and out flow  
gt30r and gt35r. The hx35 flow about 60 lb/min and the other a little  
less. I want to do most of the parts (supporting mods) you mentioned  
before than hipefully the manifold and my 250 dollar gt35r will have  
popped up by than. You should check out the compressor map on dsm  
tuners or a cummins forum. The plan is to run low boost on the big  
turbo for awhile with a nice flowing head. These are my tentative  
plans. Step 1 is doing what you mentioned to track down this boost  
issue. Than standalone and fuel system. Than turbo manifold and  
headwork. I don't see any reason to open up the block until I break  
some rods.
