gorganl2000 Posted February 16, 2017 Share Posted February 16, 2017 (edited) i've tried a search, but didn't find much. anyways, does using the thinner 0.5mm 5efe or 0.6mm trd headgaskets with forged wossner pistons allow for adequate pistons/valve clearance? and will this make the engine an inference engine or does it still remain a non-inference engine in case the timing belt snaps? and how about if stock 4efte pistons are used in the same scenario?

goldenvtr Posted February 17, 2017 Share Posted February 17, 2017 What turbo will you be running? I have built a the same 5e only with some speedvison cams. havnt decidedyet, ive put a td04 on to run it in lol its a tos up, retry my td0520, it was too laggy on the old engine but with this CR should be more drivable. or vf34/vf22 for less power but wider powerband... really dont know haha Quote Link to post Share on other sites
gorganl2000 Posted February 18, 2017 Author Share Posted February 18, 2017 if you do change from the td04 after run in, ,,of the 3 last turbos you mentioned, i'd go for vf34 Quote Link to post Share on other sites
