CHESTNUTXE 7,321 Posted August 8, 2016 Can anyone shed some light on why these green rocker cover engines are more popular on e bay ,from what i have been able to find is that they have a better conrod or the same one as the turbo engine,and they are of higher compression,im getting itchy to buy another engine to play around with and i figure go for a barra BF /FG engine and strip it down and then order some atomic gear to start to suuuuup it up for a turbo,i think from BF onwards the rod's are better than BA please anyone chime in on any good info cheer's.

CHESTNUTXE 7,321 Posted August 8, 2016 Looking to build a nice 300kw engine similar to what comes out in the xr6 T.but starting with a base engine keep the rod's,get the low comp pistons,and stainless exhaust valves fitted,if keeping it to a mild set up,probly dont need the atomic gear,with exhaust manifolds i see those 6boost ones for a lot of cash.

tpak addict 1,909 Posted August 9, 2016 They use the same rod as the turbo Barra's... or should I say the Turbo Barra's use the same rods as the egas as they were developed for the Egas first. 1 Thom reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,321 Posted August 10, 2016 i no the mahle are quite expensive ,but is there another option to loose some compression like can the factory pistons be milled 100 thou ? Share this post Link to post Share on other sites
tpak addict 1,909 Posted August 10, 2016 Dont know.... could always use a compression plate I guess.. Share this post Link to post Share on other sites
CHESTNUTXE 7,321 Posted August 10, 2016 I no you can get one for the crossy but em err yeah maybe ?-a second hand set of factory turbo slugs would be ok in a budget build. Share this post Link to post Share on other sites
tpak addict 1,909 Posted August 10, 2016 Few people have turbocharged a stock egas motor before.... Run on E85.. problem solved hehe Share this post Link to post Share on other sites
CHESTNUTXE 7,321 Posted August 11, 2016 without lowering the compression ? Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted August 11, 2016 Yep, it's quite a popular replacement for people to do when their original turbo motor goes bang. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
CHESTNUTXE 7,321 Posted August 11, 2016 I thought the gas engine was even higher compression than the normal one. Share this post Link to post Share on other sites
tpak addict 1,909 Posted August 11, 2016 Egas motor is cheaper than a turbo motor... When it goes bang, get another one.... Share this post Link to post Share on other sites
tpak addict 1,909 Posted August 11, 2016 I thought the gas engine was even higher compression than the normal one. Only on BA... BA ULP 9.7:1 Egas 10.7:1 BF are both 10.3:1 ULP & Egas FG S1 10.3:1 FG S2 (EcoLPi) 12:1 Share this post Link to post Share on other sites

tpak addict 1,909 Posted August 11, 2016 More compression means more torque.... Egas donks pack a punch when turbo'ed Share this post Link to post Share on other sites
