Max Capacity Posted June 5, 2014 Share Posted June 5, 2014 My Spec LWFW bolted to my ej255 and my ej257. So I don't see why your current FW and clutch should not fit. I never even thought about it. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

funnyman06 Posted June 9, 2014 Share Posted June 9, 2014 You don't need injectors for 300HP, but they will be maxed out. Link to comment Share on other sites More sharing options...
chaz517 Posted June 10, 2014 Author Share Posted June 10, 2014 Thanks funnyman.My buddy blew his engine at wicked big meet the other day on his 99 RS, track was closed for a bit for clean up ooops, but he was going to give me his 660cc venom injectors for my stock ones, but after researching those, they sound awful n I said nevermind. We will see what the % is in a few weeks when I finally get my car back ( this week)and break it in. Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted June 10, 2014 Moderators Share Posted June 10, 2014 You don't need injectors for 300HP, but they will be maxed out. That's dyno-dependent. If you are shooting for 300awhp on a "true reading" dyno, most of the folks here will suggest an injector / pump upgrade. Stock stuff will get you close, but as mentioned you'll be maxing that stuff out which really isn't a safe option.

funnyman06 Posted June 10, 2014 Share Posted June 10, 2014 On a dyno that reads about 190HP stock i threw down 315 340 with stock injectors and a DW65C. Peak boost is about 21psi. Like i said though, IDCs are in the 90s. For Reference Link to comment Share on other sites More sharing options...
