Hi guys,

I'm going to replace my v4 1998 sti type r engine (because I ruined it) with a fully forged, run in 2.0 engine with sti v4 heads.

As the engine is run in and is a standard 2.0 lump (but forged), can I just swap the engines and use my standard ecu with no need to remap?

Thanks

It will need mapped.

don't think it will need mapped as using the same heads

We don't know if the original engine failed due to low octane fuel on a Jap ECU. If so, the cost of a map will be insignificant compared to another rebuild!

IanK - we used hi octane fuel (99 Ron). But unfortunately, my mate installed a boost controller and was being an idiot and running 2 bar boost!!!
So I'm pretty sure the boost is the reason of the failure!! Idiot!!
