Hi all,

This is my first post on here, I can get hold of a Twin scroll engine with very low miles.

would there be any major difficulties swapping it with the WRX engine?

I understand the Twinscroll setup is different it comes with headers, turbo and downpipe so that bit is fine.

I also understand that I may need a new ecu or is the WRX one sufficient with a re-map? If not will I need a JDM STI ecu or is a UK spec one ok?

If there is anything else you can think of please let me know.

Thanks in advance

Andy

You will not be able to use the heads from the new engine as if its from a twin scroll car its an STI engine with AVCS haeds and yours isn't The twin scroll is only for the turbo and nothing to do with the engine.

Oh,

so does that mean I can just use the engine with my own headers up pipe and turbo and not use the twin scroll pipes/turbo etc?

hope it does

It sure does But as I said you will also have to use your own heads as well. Personally I would fit the twin scroll setup as well and get the car mapped for it

if you get the ecu and wiring loom you can use the lot.. but this may alsio require clocks etc..

the bottom end as said will go straight in but you should get it checked or remapped as compression maybe altered.

the twin scroll complete set up is excellent but it might be less hassle to just buy a twin scroll car etc..
