Great Buggy!

 

The best advise I can give is to get all of the engine build specs, parts list, possible mileage, and get the tune info maybe even take it to a tuner and have things checked with the tune. Is there a wideband o2 on there? If so what AFR's is it running at WOT. What boost is it running?

 

Only run premium fuel. Also see what oil has been used in the motor and maybe even have an oil analysis done from blackstone labs. This will give you an idea of engine condition, and also great for viscosity and change intervals.

 

Thye ej25d is not a boosted motor so I think you need to see what was done to allow for boost. IE: pistons, rods, etc.

 

Thats a big turbo for only 220Rwhp, on an sti motor it would give over 400Awhp. I am betting the tune is really rich and/or super conservative. You might actually gain better driveability with a smaller quicker spooling turbo. With tuning of course....
