EDIT: anyone post up #s that your d series has made and at how much boost.

I feel like such a noob asking a question like this but Im really curious. I just made up my mind that Im not gonna go all out building my ZC for high boost and Im just going to throw in some eagle rods and endyn pistons and run 10psi daily, 12 when I wanna have fun.

My goal has always been to run mid to low 13s. My question is what are some #s that you turbo d-series ppl are getting around 10-12psi. ETs, dyno #'s, I dont care.. I just wanna know where I'll be.

No sleeves with 12 psi = pushing your luck.

10 psi is a lot on a daily driven SOHC too. I currently run 8 psi daily and I'm itching to go up to ten, but I just can't do it. I get tuned again either this week or next, so 10 psi may be an option. We'll see.

 

12lbs is alot for a properly tuned ZC with endyn pistons and eagle rods?

 

No 12 psi is not alot, I've sceen it on stock internals, get it tuned and you'll have nothing to worry about.

If you're being sarcastic.. dont be. Im trying to learn something.

 

with rods and piston u can run 15+ with good tunning.

I gave you GOOD advice. Listen or not. Its not my motor. SLEEVE THE BLOCK FIRST. It'll be safer, hold up longer, and with the pistons and rods, you could run a hell of lot more than 12 psi SAFELY!

 

Tony, first off I'm not trying to be a dick when I ask this but.

Do you have experience with D series sleeves cracking? How much power (not boost) can they hold. I read that D sleeves are just as strong. They are also of the same metalurgy as the B series just a smaller diameter. I do know that prelude sleeves are weaker and made from a different material.

I'm gonna run 18PSI or 300WHP on stock sleeves whether the sleeves pop is my own problem. I just can't see ANY reason why, they would not be just as strong as a B series sleeve... If you have a reason please share.

again I'm not being a dick I just wanna hear your thoughts.

 

Good question, I'd like to know if he's had experience with D series sleeves before too.

I really dont want to run more than 12psi right now.. I just want to have something that runs mid to low 13s and Im not trying to spend much $$ on this setup. I already saved a grand+ going with a ZC instead of a B16. Im about to buy a greddy kit with 6K miles on it for $800, only thing missing is an intercooler. When Im ready I just want to spend another $600-$800 on pistons/rods and be able to hit the mid to low 13s that I've been wanting. Sleeving the block costs more than I paid for the entire damn engine.. I'll wait till Im out of college and have a 2nd car and stuff before I spend alotta $$ on the turbo GSR that I hope to get done. Right now I just want to have a quick daily driver for my last year thru high school and my college years.

Your location states "Jinxproof brown noser." I think it was him that ran a HUGE amount of hp on a GSR with ALL stock internals, except for an Inline Pro headgasket. I've seen sleeves crack at around 200 hp and I've seen them hold up at 400+ hp. Tuning is definatly the key, but if you are going to build the motor with rods, pistons, etc., why not sleeve it to? Why risk a motor?

 

You do know that even with forged internals, if the tuning is not done properly the engine can be severely damaged? Spending a lot of money on strenghtening the engine is only buying a certain level of insurance. That money is better spent on better tuning of the engine IMO. I am not saying that noone should use forged pistons/rods/sleeves. I am just saying if you are going to build up the internals, just don't forget that excellent and proper tuning is still a MUST.

 

With 15psi you will be fine. i have ran 18psi on stock sleeves with out any problems!!

I dont care what these people think!! I know you can do it!! i know from personal exsperiance.

Now if you build it with sleeves then the sky is the limit!!!

I couldn't have said it better, you have to build it then tune it. You can't just do one, that's like chewing and not swallowing, or swallowing but not chewing. You have to do both.

 

I run 10 psi daily. I have been for the last 6 months with no problems. I run the car hard and i track it at least once a month. If the car is tuned properly it will be fine. Btw this is with completely stock internals. We are going to be adding headstuds, thicker headgasket, Y8 intake mani and 3bar map sensor, then tune and up the boost to 15psi in about 2 weeks. I know it can be done. I know of 2 people personaly that have ran this setup for over a year with no problems. Tuning is the key.

 

The sohc cam sleeves are made of the same material as the b-series sleeve. I know first hand that all stock internals the b-series can withstand 20+psi. I push a stock block gsr with a thicker headgasket to 18~19psi on race gas while I had down time for my built block. This was stock pistons/rods AND stock sleeves. The turbo was a 60-1, so I was making well over 400whp. Tuning the is the key to utilizing the stock components. TSohc-Tec's freshly built d16 engine just had some boost ran through it last night, and Saturday were heading down to the dyno to make 300whp on whatever psi level will suffice. He has the Toyota supra/B16a rod combo on his bottom end. No block guard, no sleeving. There will be zero problems. Detonation kills the sleeves, if we arent detonating the sleeves will hold.

Another aspect to illustrate how strong the stock d-series sleeves are is dictated by the bore size. The smaller bore (same thickness) will always be stronger than a larger bore (same thickness). The larger bore size tends to distort under higher stress since its moment of inertia is much larger, and is susceptible towards bending loads.

 

I'm getting tuned this Saturday at Xotic Motorsports in PA. We'll see what my completely stock internal D16Y8 can do. No Hondata, just the VAFC hack w/ an Uberchipped OBD-1 ecu .

 

We have ran SOHC vtec motors on 20-22 psi with just a piston/rod setup. Been runnin strong for a couple years now. Like they are all saying... its all in the tuning. find a good tuner and you will be AOK.

 

i have ran my stock internal sohc at 14psi for 3months straight of just pure *** whooping on the motor and then turned it up to 16 and did not blow. i overheated it due to a bad fan, warped the head, hydrolocked cyl3 so the motor blew at the track and that was when i was going over 20 psi, and the cyl walls are fine no cracks or anything.

 

I'll be running 10-12 on my stock z6 once I install injectors, V-AFC and tune it. Right now I'm running 8 and have been daily for over a month now. I beat it too
