StephenA Posted August 16 Share Posted August 16 98 2.5 frankenmotor build. So I'm looking at the 2.5 headbolts. Am i to remove the cams in order to get the head bolts out? The Haynes manual is as helpful as a milk bucket under a bull. It tells me what order to remove the bolts, but nothing about how to access the bolts with a socket. I cant wait to get these heads off and put the 2.2 heads on. Stephen Quote Link to comment Share on other sites More sharing options...

StephenA Posted August 17 Author Share Posted August 17 Thanks. I guess I'll just go bang on those cams. Quote Link to comment Share on other sites More sharing options...
ocei77 Posted August 17 Share Posted August 17 once the bolts are removed they'll come right up. Watch the torque on install if you want to keep the heads. They are INCH pounds not foot lbs. O. Quote Link to comment Share on other sites More sharing options...
StephenA Posted August 17 Author Share Posted August 17 Not bothering to save the heads. ill reassemble them loosely in case someone else wants them. Id rather stick with the 2.2. First time with a frankenmotor, but I'm keeping the 2.2 from the car intact in case I build this motor wrong. Having fun either way. 1 Quote Link to comment Share on other sites More sharing options...

Dohc ej22e - Second Generation Legacy (1994 - 1998) - LegacyGT.com Fun, but sadly non engine issues killed it. Quote Link to comment Share on other sites More sharing options...
StephenA Posted August 17 Author Share Posted August 17 thats an interesting combo. smaller block but with better air/fuel flow. truly, subaru is a lego set. Quote Link to comment Share on other sites More sharing options...
ocei77 Posted August 18 Share Posted August 18 Keep everything. The 25D headbolts are a different length than the 2.2. Also the mounting point and the dip stick length are different. The ect may be different and depending on the year may be in a different location on the crossover pipe (ie: front or back). More power to you Quote Link to comment Share on other sites More sharing options...
StephenA Posted September 21 Author Share Posted September 21 Thanks for the advice. I've been taking note of the differences. I'm guess I'm using this as a learning experience. I just hope it runs. Sorry for the delay. Life suckerpunched me and I'm just getting back to this project. I need it running because I'm selling my other outback.

Numbchux Posted Monday at 03:23 PM Share Posted Monday at 03:23 PM I think it's clear what you're working on. But for future reference. DOHC subarus (I think all of them, certainly EJs) require removing the cams to access the head bolts. SOHC engines do not. 2 Quote Link to comment Share on other sites More sharing options...
