4agze to 4agte
I own a ae86 4agze and just starting 2 buy inlet mainifold, turbo mainfold and turbo just wondering if any one has tips in the process of change over its a map sensor'd 4agze will i get away without having 2 change the ecu and is there any big wiring changes that need 2 be done thanks

after market ecu is desireable but stock will be fun. can't run that much boost on stock ecu though.
T18 in the build
I've done the same thing but i ran an Adaptronic ecu. There cheap enough to run and do 100 times better than a stock ecu..
**Sorry not to really answer your question. Just my experience**
OK, I haven't done this myself, but seen the results a few times.
Just remove SC related stuff, bolt up turbo manifold, turbo and a suitable intake manifold. Sort out intercooler piping. Then the thing should run fine. I've seen it done on stock ECU plenty, and it works. Yes an aftermarket ECU allows tuning for improvements, but the stock one works.
There'll be some vacuum lines that need to be rerouted/sorted out, but they are simple. Only electrical issues I can think of are TPS (which may just need a different plug, but I seem to remember some bigport to smallport TPS change on the NA manifold), and idle control (you can get by without it, use the temp controlled idle valve on the NA manifold or mount the ZE valve somewhere).

yes very doable and i suggest everyone with a map 4agze in their car to do so. runs on standard ecu fine. 6psi on a t2 is plenty on a 4ag and i wouldnt run anymore than 8psi unless you have an upgraded driveline.
be careful however how you shift if youre running a t50. a w5x would be the next step to take before an aftermarket ecu.

yes i did fail she was 14 what u expect(shakes head)
works great limited to about 12psi tho.
thers a boost cut at about 13psi i think but can be sorted with an fcd
maps have a 14.7psi boost cut .. AFM just blow up with unlimited boost
