As many of you know I'm going to turbo the 7A.


So first things first, with the help of Garrett's Turbo Tech 103 (Expert), I did the compressor flow map calculations... try to follow along, if you have any questions just ask...

here are the EQUATIONS:


and the CALCULATIONS (for a 7AFE with a target of 200hp at the flywheel):


then you need to plot some numbers on the COMPRESSOR FLOW MAP of your choice
I got a small Garrett 2052 which should be enough for my goals


From just looking at different compressor flow maps you'll learn a lot. In general, the closer the turbine and exhaust housing sizes the wider your power range will be but the maximum boost level is limited. When the sizes are significantly different you'll notice the compressor map will look taller and thinner, that gives you a smaller RPM range you can boost in but you can achieve higher boost levels in that range.

I got some Supra lime green top 315cc injectors from Manny (presure2) which I just sent out to be cleaned and flow tested.

I bought all the lines and fitting for my oil filter relocation and oil return, I'm working on the oil feed items.

Peter, the tech at work, his brother-in-law does some machine work so he had my oil pan drilled and tapped in the place we had decided on.

we put some kind of metal putty stuff just to reinforce it a little...


kind of blurry but just so you can see about where it is


and just for reference, you can see on the bottom what it used to be. of course we made sure it wasn't used for anything first...

im quite positive he can reach 200 on flywheel with this turbo as long as this turbo able to flow 220cu ft/min

u must mean SHE can reach that goal

yes its true. I am a girl.
