bigport to smallport install

[sketchy]

Hello,

I am interested in installing the smallport 4age into my ae86 so doing some reading on how people have done this. I have a few questions that i'd appreciate some advise on.

One issue i have come across is the inlet manifold. The smallport (non t-VIS) engine is a FWD application and so the inlet manifold points the opposite way to the RWD T-VIS version. This needs remedying to complete a successful install!

One solution i have seen is to use the RWD inlet manifold but remove the T-VIS from the RWD 4age inlet and install the T3 bigport to small port adapter (https://technotoytuning.com/toyota/16v4a...rt-adapter)

The other method i have seen is to cut'n'shut the FWD non T-VIS inlet to work the other way round so the throttle body etc. does not point towards the firewall.

Does anyone have advise on advantages/disadvantages of both options? Of course i could go ITB, but thats a project for another day! At the moment i wish to keep stock ECU.

Presumably if keeping a stock ECU i would need to use the smallport one rather than bigport? Would the smallport ECU give me any problems with the loom/electrics for my ae86?

Thank for any input.

James
