Hawkeye sti jdm limits
 
Hey guys am new here. Have put a deposit down on a 2005jdm impreza hawkeye and was just wondering what sort of power you can get on stock internals? And what would i need for a stage 3 map? Apparently it has a iHi vf37 hybrid turbo kaki moto exhaust but I don't know what else has been done.

Welcome
With vf37 oem top mount and exhaust around 360, should survive 450 horses for a while with right turbo ,exhaust, intercooler etc.
Needs front lip spoiler me thinks.

I'm thinking about possible keeping the top mount and running water meth for cooling to keep the temps down

I agree it does need a front lip also need to get a sti seat as it has a rigid bucket seat in it

On pictures looks like it has oem 4 pot brembos on front and 2 pot on the back, jdm comes from factory with front sti strut brace,some comes with wind deflectors and tinted rear windows.
Have You auction sheet,grade?

Phil91940 05 May 2023 07:27 AM

No I haven't . What are the standard brakes like?

stockcar 05 May 2023 09:41 AM

the later JDM 2.0 cars use the same Hyperpeutic piston manufacture as the 2.5's and ultimately can suffer the same fate of ringland falure......
personally would be wary of running one above 400 for this reason, earlier 2.0 cars ran a factory 'forged' piston and would be safer at mid 400's albeit your then into potential for rod / gasket / head bolt issues on a std engine

Would it be the later or earlier engine in mine thanks for the responses

anything after MY03 JDM wise is a 'later' engine so the above applies specifically to yourself.........
