I have a GE block that has been Bored .40 over , Now the Question I have is would i benefit if I where to get a set of 3SGTE Cams ??? :? What do you think will be the HP Gain? Like I said it bored .40 over and has bigger pistions...
3sgte cams have less duration.....alltrac owners put our na cams in there engines ..i know hks makes cams ,google it or alltrac.net it.
The 5sfe has a Crank that will fit- If im not mistaken-? :? im wondering if the Duration on our stock cams is more efficent than an aftermarket set- seeing that the pistons are oversized? :?
the 5s crank will make it a good stroker motor, you have to machine the main journals to fit a 3s block or rods...don't remember the GTE cams are worthless in an NA motor.
mad props to alltrac.net where I got this from crazy_russian All Trac Club Member Joined: 10 Nov 2005 Posts: 139 Location: Toronto, Canada PostPosted: Mon Jan 01, 2007 5:22 pm Post subject: Reply with quote Here's 1st gen info for completeness. I got this from Mario ( st185-sainz ) 1.gen 3SGTE (st165) In: 232deg, 7.15mm lift (timing 4/48 ) Ex: 232deg, 7.15mm lift (timing 48/4 ) 1.gen 3SGE (st162) In: 240deg, 7.2mm lift (timing 5/55) Ex: 240deg, 7.2mm lift (timing 55/5)
ok- its come to this either just knife edge a GE Crank- or go for the 5sfe and knife edge that- which you all consider better for a road course race??? :?
in a road course the first thing that should be addressed is suspension and aerodynamics, not HP. On that note: i would go for the increased displacement of the 5s crank, making your GE a 2.2L. forge out the bottom end with balancing so you can get the bottom end ready to hold high revs consistently. then have the crank champhered, knife edged, and balanced as well. sounds like you'll be wanting to contact chrisK or ATS racing.
OK after many hours of research and muscle tenseing up- If found what i was looking for, Now this will benefit alot of GE owners in here!!! As youve all read in the above post- Im in search of a few ponies in a GE block- so what I have found is : A 5SFE Crank and Rods can go into a GE block !! Without any machning. this will in a grey area make a Stroked GE Engine. Now due to the fact im limited to what I can produce from the block- Im going to use the stock GE rods- with a 5SFE Crank (machning the gernals will have to be done! This guy has become a God to - and ive already made him frusturated with all my questions lolol http://www.mr2oc.com/showthread.php?t=132687
you really need to get ahold of chrisK on the mr2 boards. he will answer every question and it'll be for your motor.
