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.

Hey guys, I'm the Piloter who's doing the 7AGE build over at ToyotaNation, just thought I'd stop lurking and drop by for this thread in particular.
I've been doing some intensive modeling of the 7AFE/7AGE/7AFTE/7AGTE/7AGZE/7AFZE via Engine Analyzer Pro and trying to get a selection of compatible turbos/superchargers programmed in as options, thus I've been reading a LOT of flow maps. This was originally created for the VW guys, and I've modified it slightly to give conversion factors of airflow in pretty much every unit possible, you'll just have to modify the VE at your discretion and plug in numbers to boost RPMs and PSIs. http://rapidshare.com/files/59382057/18tCo...ctions.xls.html I have to head to work right now, but just off the top of my head the best turbos to start looking at if you want 7 PSI by 3K (what I've been simulating for) would be a GT2552R or a TD04-15. The GT2862RS ('disco potato') and T3-'Super 60' will both come up on 7 PSI by 4K, but that's with the flow figures for a bigport 16V head. Hope this helps. |

I have already bought a turbo. When I get some time I'll post up the compressor map for it and explain where to plot the lines and how to tell how much boost it will make and when.

but for now I'll introduce the rest of my turbo project...
What little things I have so far: AFC Neo Fuel Controller  Oil Pressure and Boost Gauges  Manual Boost Controller  2 Bar MAP Sensor  Rebuilt 7AFE waiting to be put back together and boosted  Log Style Exhaust Manifold (I can't find the picture of it... and its at work so I can't take one) Turbo (being FedEx'd from Canada at the moment) -------------------- |

Once I add more about the calculations and actual flow maps I'll see if someone can move it around so it's all together and away from all my turbo setup stuff. -------------------- |

my turbo is here... and its little, just like everything else in the 7A, perfect match if you ask me
I tried to give an idea of size with some of the pics but it just makes my hand look big... so keep in mind I have tiny hands...      -------------------- |

that looks similiar to my turbo hmm!
-------------------- the 1/4 doesnt have patience for a ST.... so we make them ST-T's so atleast we'll sound good going slow.
