I plan to start my turbo build in 2018. I am easily blown away with some other members comprehension, in regards to turbo/tuning knowledge. I recently stole another e30 with a 91 m20 swap. (I bought the car for the blower, paid 220 for a running e30 w/title). So I plan to build the spare engine for my current car.
I have read Maximum Boost earlier this year, and plan to read it again as I have learned more since.
Here is the plan.
Engine: m20b25 stock
HD Rockers
Con Rod bolts
Supersprint Valves.
OEM Gasket
ARPs
(piston rings if needed)
Skimmed/Decked block and head.
How many people suggest the water jackets to be welded? 400hp is my maximum goal. Getting the project started/moving I will probably run anywhere from 6-9 psi and plan to turn it up to 9-15 once said and done.
Engine Management: Build-a-squirt, running distributor, unless I can grasp (mentally) wasted spark set-ups. I realize how they work, I just don't want to burn out coils and would like to keep it simple.
Turbo: HX35 or Precision 6266/6262.
Cheap intercooler and whichever decent manifold I can buy/have built.
I have seen 38-44 wastegates being used, will look into it further.
This is the generic pre-build list. My main concern is tuning.
Where is the best place to learn tuning for VE, spark, fuel? How much do you trust Autotune? VE confuses me the most, being honest. I know there are calculators to spit out numbers. I would rather have the understanding of why the adjustments need to be made. All I understand about VE is, it should be adjusted based on atmospheric pressure ( considering barometric pressure when figuring the number?) as well as calculating the amount of air that is being forced into the intake. So, do I adjust accordingly with MAP/IAT levels?
I plan to have the engine prepped by the end of this year and have MS running (NA) early next year. Hopefully boosted by Summer or Fall. Should I grab a good base map and watch the tables live, with datalogger in the background?
True tuning novice here. Please excuse any ignorance, you're welcome to laugh if I am in left field.
Thanks again for anyone that can transcribe my poor intellect and making a valid response!!!
