Ok ive been thinking i want to later build another block up. I thinking of going w/ this setup let me know if this will work.

GE sleeved to 87mm and 100mm crank now what rod lengths do i need to run this setup? If im correct the 87mm should make it close to 2.1 will the 100mm crank make up the remaing .3 to make the full2.4 is this possible? What length rods will i need is there a formula for this. This would be a full race motor also wouldnt this kill my rod ratio.

Also any manufactures of crank that big i dont want to use a deckplate is that possible?

Anybody of similar setups got some info this will be used for allmotor chores w/ compression in upwards of 14:1.

 

that is some serious bore. i dont know if 87 mm is possible. 81 to 87 is quite a jump.

 

its possible if sleeved i know this already

 

with money anything is possible !!! the part about going out to 87 mm is possible but you might have problems with ring seal, I dont think anyone makes a 100mm crank though and without using a deck plate your R/S would terrible.

 

Yea, you're planning on running a deck plate right... The farthest you should be able to go is ~89mm, offsetting the sleeves... I've never built a high compression motor that big and if you do i'm sure TUNING will be FUN This gonna be a straight race motor??? My friend's race motor is nothing special and a lot less expensive then what this setup would run... GE sleeved 2.0L LSVTEC running 15.0:1 Ross pistons (which are weird, they have a pyramid dome), we used to have JE 15.0:1 slugs in it... Portflow head, SK2stage3 cams, ITB's, Hondata, it made 260whp and 162wtq... It ran an 11.40@117 last season but that was with a STOCK B16 tranny w/ Quaife LSD and MT 24.5x8x13 slicks... Those damn slicks are too tall even for that B16 tranny and we were finishing at my friend was shifting into 4th just as he crossed the 1320 mark... Oh well, we'll see what it can do this year with a custom tranny, different slicks, and the SpeedPro... Hopefully some 10sec passes... Anyways sorry I went off but my point is unless you're trying to build the fastest NA race car I wouldn't spend my money building a 2400cc motor.... Good Luck!!

 

That combo would yield a 2.377 L motor. More importantly, and I think someone mentioned this, your R/S ratio is going to be crap, dictating a redline of around 6k. Why not simply biuld a B20? same (mediocre) rod ratio as the LS, but with 2.0l and no real drawbacks(like having to spend an ungodly amount of money).

BTW, Im pretty sure the rod length on that would be 148mm. rod ratio would be 1.48:1, obviously.

 

Question re: GE sleeved 2.0L LSVTEC running 15.0:1 Ross pistons (which are weird, they have a pyramid dome), we used to have JE 15.0:1 slugs in it...

At 15:1, what were you doing for fuel / engine management?

Thx,

Mark

 

I've never heard of such high compression, thats sick.

 

RC 550's and Hondata... The motor was actually running well but not fully tuned on the top end.... Peace

 

who makes 100mm cranks?

or do you mean 95mm?

my setup is 86 bore 95 stroke street 12.5 compression

 

and thats 2.2 Litres

 

you can make a 100mm crank

 

http://www.rddyno.com
They make 2.4 liter blocks.

 

Iv'e seen a 2.4 that made 290whp 210tq it was 101x87 if i remember right. The car disapeared like a year ago

 

Who makes a good stroker crank, and Rod combo for a 1990-1993 LS motor? I want to gain a little bit of Rod to Crank angle also, not just lengthen my dang breathing stroke.
Rod to Crank ratio is a great way to achieve more torque. Just don't overdo it. I have seen people 'notch' the bottom of their piston skirts, or the cylinder walls or even the inside of the crankcase to achieve a desired R to C Ratio.

Please tell me who makes a stroker kit???

thanks,
Scott

 

Crower is the only one that i know of (for the LS) other than that rddyno site. I'm sure others do to.

 

Eagle specialty makes the best stroker cranks...

 

i dont know about the best but they do make stroker cranks.
