Dre simply stated that a change in CR wouldn't effect the whp/psi made. I simply took it to an extreme case to prove a point. Changing the CR of the en...
VE of the engine affects the flow rate of the turbo based on the pressure ratio and adiabatric efficiency. Without going much further into detail, I can tell you for certain that WHP/PSI will chang...
I would try a new DVM to make sure. I have found a lot of the cheap ones when connected directly to the battery read too high, and working in a parts store I see it more often than I should.
Man, with all this talk of 500whp+ on pump gas I don't know what to say. I know its a big turbo, but i have yet to see any car around here in the 2.0-2.5L range make anything close to that on pump,...
I've built 3sGTE/5sGTE hybrids before. With ported head, big cams, and 2.2l it was very slow to even boost a GT35r with a .63. I guess it just depends on what you call sluggish, as it is based on i...
Ya i figured it wasn't TS considering you said only one wg. The TS would prob benefit mid-range a bit. It cuts about 5% off the total capacity of the turbo system though, because of the smaller hou...
That thing has to be built to the nuts man. Ported VE head, wow. Nice build, was he able to run twinscroll on the GT37 or did he run an open housing? Which AR?
it uses rpm vs speed calculation. The boost by gear works ok, but i wasn't able to set mine up all the way because the AVCR i was using was old, and everything was in Japanese lol.
stick with stock cams and call it a day. the SR16 cams have way to much overlap to dial out with cam gears. 70* worth of overlap. the SR20ve cams only have 48*.
This is interesting because my turbo spools just as fast as a GTiR t28 setup, and only ~200rpm slower than disco, even at higher altitude. Just saying.
i used the window weld and it worked amazing. Way better than my prothanes. They held up great, but there is a right way to do it. You have to clean your old mounts really really well and dry them....
I should also say that the regular VE cams will likely work better with mid-frame turbos. the sr16 cams have a lot more overlap and won't come alive until running a rather large turbo.
I used the ARP2k studs and they seemed to work ok. I didn't like them because the torque spec is 105ftlbs which is way too much in aluminum imho. I thought they were going to strip out really bad.

How do you not get traction on the street? I don't start spinning 3rd until making over 420whp. Unless you have a really worn out lsd, you won't be spinning 3rd until making a lot more than 400whp,...
You gain a lot of powerband in the mid-range when going the big-boost-smaller-turbo setup. But keep in mind that some of these turbos will retain a lot of heat under high boost and can cause some h...
They are more conservative. They are obviously tuned off of a very large turbo car. The timing maps are conservative across the board, but that is ok. I just run a 17* advance and the tune is prett...
the rear mount battery setup would be awesome on my car. But they won't let me track the car with a rear mount battery without having a stupid kill switch.
There is little point to switching maps when switching vvl. The tune is based on airflow so technically the DE map will work on the VVL. But your cold start idle will be ridiculously high. Overall ...
