5e colin Posted August 5, 2014 Posted August 5, 2014 yes in gen 1 they look identical but are less strong gen1 will hold 11/12psi daily and gen1 4efte rods go past 18psi not to fund with gen 2 they are both shite 4efe and 4efte Quote
Glanzacoley Posted August 5, 2014 Author Posted August 5, 2014 Right I have a mk2 gt turbo which I need to change a Conrod in I have 2 4efe engines paste one out of a 96 glanza S & the other is a normal uk spec starlet 4efe can I use a Conrod out of one of them for my mk2 gt turbo? Quote
5e colin Posted August 5, 2014 Posted August 5, 2014 no it will be unbalanced use 4x 4efe rods then they weigh diferent by few gram Quote
Glanzacoley Posted August 5, 2014 Author Posted August 5, 2014 Ok thanks is it possible to change rods without removing head/crankshaft? Quote
5e colin Posted August 5, 2014 Posted August 5, 2014 no and to your other thread regrind on crank for sure or go scrappy and buy 4efe engine and use the crank Quote
Glanzacoley Posted August 5, 2014 Author Posted August 5, 2014 I've removed scores with wet & dry mate What would you suggest now? Quote
5e colin Posted August 5, 2014 Posted August 5, 2014 you cant just attack a crank with sand paper it needs to be measured with micro gauge to see if its still tru al the way round if yoy scimp out now it will bite u in tyhe ass later trust me been there before !!!! Quote
mikey4410 Posted August 5, 2014 Posted August 5, 2014 Yeah as above.a crank has to be PERFECT otherwise will last a few minutes and then die. Quote
daniel_g Posted August 5, 2014 Posted August 5, 2014 This is why its a fuckin minefield trying to buy a starlet or an engine for one. Too many clowns chucking them together and buffing the cranks down with sandpaper. Quote
fiddlersport Posted August 5, 2014 Posted August 5, 2014 sandpaper on the crank, first time i have heard that lol most people ask whats the best or who can do a good regrind on the crank... what grade sandpaper anyhow ? this will be funny !! Quote

_shaun_ Posted August 5, 2014 Posted August 5, 2014 Nah ull be fine with sanding the crank down just make sure you sand the new bearings down to match. Another top tip is rather than trying to torque the big ends down properly just pop a few cable ties on jobs a good un. Quote

AdamB Posted August 6, 2014 Posted August 6, 2014 There's no problem with polishing a crank with sandpaper providing that the crank is continuously rotated ie when its on a dynamic balancer. Quote

Ask Full Race how they do theirs Quote
