Time for the build... I know safety first when it comes to motors but do I "NEEED" to sleeve my GSR block? I plan on 400HP MAX with t3/60-1 at roughly 15-18psi... i have read about stock sleeves holding 600whp, but how long does that last? How often does a cracked sleeve happen?

If i dont sleeve motor will be 81.5MM bore b18c1, CP 9:1, Eagle Rods, Cometic headgasket, GE blockguard, 720cc injectors. Hondata tuned by Ralphy of DRT....

 

Looks like my set-up minus the block guard and i have slightly higher compression.

 

i have a stock bore b16 in my 99 si turbo charged with

8.5:1 JEs
crower rods
str block guard

i have been boosting for 2 years and made over 300 on a daily driver, NO SLEEVES.

how many people do you actually KNOW personally that dropped or cracked a sleeve?

i dont know any

 

look at nextelbuddy...he just hit 400 on stock sleeves(i believe)
he has a blockguard

 

I met up with someone who had a gsr motor in a hatch, stock sleeves, but forged internals. He was running 450whp, hondata tuned by raphie at DRT. This was on race gas, but his car was fassst. I am building a b16 with stock sleeve and I'm shooting for 500whp, should be finished by the end of summer.

 

when ralphy tuned my car i made 294 on stock everything gsr... the sleeves held up fine, it was just the 150k that was on my motor previous to boost that didnt like that much power (spun bearing, bent valve, couple cracked ringlands...)

 

If your going to pull the motor to put in new pistons and rods it doesnt take anymore effort to have it sleeved. Its only another grand. Im sure people have made crazy power on stock sleeves before but you have to expect it to pop eventually when pushing that kind of power. Why BS around? Just sleeve it and make it bullet proof. Thats just my opinion.

 

My engine has been together for three years with stock sleeves, arias pistons, eagle rods. Went 11.4 at 130 on high boost and spinning 1-2.

haha, thats what i was thinking, "only" another grand, hell thats "only" my house payment.

 

well the way I think of it is. you are already putting together a nice motor. why not sleeve it already. at least if you ever decide to boost more or take it to the next level. its already done and ready to go.

 

Look at it this way, is it cheaper to sleeve the motor or build it twice?

It is always better to spend more now than it is to spend A LOT more later IMO.

Its your car, roll the dice if you want to.

 

you would be much safer sleeveing gives you a piece of mind
And even better if you wouldnt leave your car with DRT (Dominicans Robbing Thiefs)

 

haha yeah only. You guys know how much money is spent on making our cars go fast. Whats a grand to make it bullet proof? a Full race manifold costs a grand, a nice turbo costs a grand. This seems like the most important part to me. "only"

 

im doing a build soon and i cant decide if i want to sleeve or not. you have it apart so why not and why risk cracking a sleeve when you can sleeve it a be good to go..
i dont know.... I JUST NEED MONEYYYYY

 

With a good tune you should be safe at 400whp.

just because you have a sleeved motor doesn't make it bullet proof. Without sleeving and saving $1000 (give or a take a couple of $100.0), invest in a nice standalone.

Its about as "bullet proof" as one can get. Its your opinion that sleeving isnt nessecary and it may not be but its going to be the weakest link latter down the road. It makes sense to do it now while the motor is out.

whats the point of sleeving if "said person" is going to run the hack or something like it?
If he plans to run the hondata (not a true standalone but thats a different subject and hopefully I didn't open up a can of worms )as he stated above, then he already has that included in his build and if there is ~$1000 left, then yea go ahead and sleeve...but if not, save the money, buy a "true" standalone and tune (can't say this enough) using stock sleeves

The problem with that is the motor is much more fragile. You will be constantly on the razor edge. Even small amounts of detonation will crack the sleeves at that power level. One day you might be in a hurry and grab the 87 octane pump without realizing it. Also keep in mind that a motor is a lot more prone to detonation on hot and humid days.

With a sleeved motor you might actually get away with stuff like this, but with the stock sleeves you won't.

 

im going to sleeve.

 

I agree with 4-banging. Your engine is only as bulletproof as your tune is. Sleeves on a motor that's running lean as hell and has way too much ignition timing is NOT bullet-proof. I would invest in good engine management before sleeves.

 

hondata equipped.

You should be good to go, if your tuner is good.
