my friend just put eagle rods and JE 9:1 compression pistons in his 00 gsr. he did nothing with the block, how much boost can he handle? i know he wants to do 20 psi on 116 octane. can teh cylinder walls handle this?

 

Yes, from what I've heard the cylinders walls can with very good tuning.

yup i heard around 500+ with tuning....but don't hold me to that

 

With extremely good tuning maybe, I think 400hp is pushing it on stock sleeves, let alone 500, but I have seen stranger things. Standalone would be a must and maybe you would want to look @ Crower rods, some people are shady about eagles....Good luck tho

 

thats it? you dont need to bore it out or anything? just take off the head and put new pistons in and rods? what about 8:1 compression? and up the boost even more? anybody with experience on this? i would like to know the best setup to do wiht stock sleeves . thanks.

bump

 

the stock sleeves can... but for every one person who has gotten away with running 400hp on stock sleeves there were another 4 who cracked em.

tuning is obviously the key, but so is luck.

if you're going to tear it apart, it's best to have it sleeved.
8:1 compression would obviously be safer, but not when you're going to have to up the boost even more to get the same amount of power that 9+:1 would get with lesser boost.

9:1 compression is fine. you have no idea how horrible 8:1 feels before boost.

the more important question is what is your friend's fuel set up? and what form of engine management is he using?

 

he will be using hondata or something simialar to it wiht 450cc dsm injectors

 

we had stock LS sleeves crack at about 575whp.. held 460 really well.

Obviously those numbers are on race gas...what do you think about on pump(93 octane)..

 

Sleeves don't know what type of gas you're running. Pressure is pressure to a piece of metal. But yeah, that was with race fuel.

Once again, obvious information..i was just wondering what kind of numbers you guys put down on pump gas

Me too, since my goal is about 350-400 hp....and it may save me from having to do sleeving work since i'm broke

 

do you guys that dont sleeve your blocks just take the head and oil pan off and put new rods/ pistons in and still make really good hp?

 

under 400 hp stock should be fine. we have a gsr with stock sleeve, eagle rod, je, dyno out to 360 and run a consistant 11.8 @119 in a daily driven ek. it's been racing for about a year now.

actually, this is the first time i've had a stock motor with boost, so i was just interested in what other people have done..I really see no point in doing pistons and rods and not sleeves....i just want to see what the stock ls($450 special from arturbo) can do...I know every set up is different, and it might not last a long time either...

 

&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt; stock sleeves

306whp at 12psi

 

306 at 12 psi thats it?

yep, the components and the tuning is the key really. there are quite a few who run 350-400WHP on stock sleeves, and some that have reliably made 500WHP on stock sleeves for a length of time. tuning is the key and how everything is setup as well.

yes easily put that is what's done. but you have to realize that there is a considerable amount of prep work done, the new rods and pistons aren't just "thrown in there".

all the clearances need to be checked, the cylinder bores need to be "round" and not oval with the correct clearance for the new forged pistons. bearing sizes and clearances need to be checked, with the correc bearings installed. piston ring gap needs to be set and aligned on the piston correctly. and of course everything needs to be very clean when reassembling a motor, can't have it done without thought etc.

also some cylinder bores need to overbored slightly to bring them back to "round" for the proper clearance all the way around the piston. this may require an 81.25-81.50mm bore size instead of close to the stock 81mm bore size. if you just installed 81mm pistons into stock sleeves without checking clearances and doing the needed honing, the rings wouldn't seat correctly and one side of the piston may be too tight to the wall, whereas the other side may be too loose etc.

but in the end the rod/piston package can yield a nice reliable power increase over the stock items, even with the stock sleeves still being used.

 

I have a friend that puts down over 400 to the wheels(18 Psi) with Stock Sleeves. I think it is ok to do 18 on Stock Sleeves with Race gas. He runs 15psi(370hp) daily on pump gas.

450's? your nuts. 500 whp needs about double that.
not to mention hondata disowns DSM injectors clearly on their site.
