GrimmSpeed EFR7163 + Bottom Mount Header with EWG


Recommended Posts

Yes the downpipe would need modification. But more importantly, the header will not fit an EJ block and will need significant modification too. Since this is made for the FA motor, the exhaust ports are not the same distance apart from side to side as the EJ motor.

Very interesting. We would also need a modified downpipe for this, true?

 

Probably lots of modifications. Ignoring the downpipe and looking at only the header I doubt the ports coming off the FA20 engine are the same as our EJ25. Still, might be easier to make that fit than building from scratch...

This gentleman from Aussie land just threw down 504 on e85 at 28psi. Turbo is the EFR 7670 1.05 A/R twin scroll (external WG) has plenty of room left for more power. Keeps blowing intercooler piping.

On p98 fuel @19psi made 384.

 

But wait THERE'S MORE!!!

Not knowing much about the FA motors I would guess there would be far more fab work involved to get this kit modified for a 5th gen LGT.

 

I haven't looked in the engine bay or under a new WRX. That being said, I'm thinking of space limitations and differences revolving around subframe, motor mounts, oil pan, oil scavenge, etc. In other words way more complex than just the different spacing between the exhaust ports.

I may, or may not, have possibly known, or not, someone who thought this was a great idea and may not have ever been caught...

 

Honestly though (besides cost) why is this a bad idea? How do they "catch" you.

 

As long as you have a motor from your model, isn't the answer just my last one exploded and this was the cheapest way to get it running again?
