DOHC Reliability > SOHC reliability for boost?

[99Geezer]

Ok I realize that there is a huge difference when dealing with a SOHC and a DOHC. I use to have a turboed d16y8 and the reliability was crap. It seemed like every week needed something done, and went through 1 block and about 2 or 3 head gaskets running about 5 psi daily driving, driving it somewhat easy. The point of this thread is that if I do decide to turbo my gsr, will it be much more reliable then the single cam that basically wasted a lot of my money.

Really their BOTH reliable. You must have had a bad tune to do that to the SOHC. But the B18C is stronger and a better motor by far. But if you use a bad tune then you will have the same problems.

anything will go to shit if its not done properly. you can have the most reliable build but if its not done right it doesnt matter if its on a $100,000 porsche or a $10,000 teggy

if done right, they both can be very reliable, and if done incorrectly they can both prove to be troublesome.

as said above it's all in the tune and what you are using for management with your setup...if you have an inefficient setup that will not accurately tune your car for boost you will have problems...i have heard of guys with completely STOCK gsr engines run 10-12 psi and get 300whp out of them and drive them daily with no problems...very impressive and can be done with the right tuning and setup...i am hoping to get 250 whp out of my stock gsr motor once rebuilt.

Either SOHC or DOHC are both reliable... did you have it tuned correctly? There's no reason for head gaskets and blocks to be blowing out left and right unless it just wasn't tuned the right way. Turbo=TUNE. they work hand in hand, can't have one without the other. You're just askin for trouble lol. GSR's are good motors to turbo, but if you want to be on the safe side, or if you want to run a little more boost, you should build up the block and the head if the funds are available. Then you'll be steady running 13's with good fuel delivery and tuning.

you ever heard of tuning?

 

[99Geezer]

yea i did have it tuned by a local shop in wichita, i guess they didn't know what they were doing.

Old thread FTL.

I know this is an old thread but d-series are not as stout as b-series. They have really weak rods and cylinders, they're bearings aren't as wide as b-series so you have less contact (more friction on a smaller area, not going into the physics of it). There's a lot of things that make the b-series better for boost right out of the box, tuning has nothing to do with any of this. You can tune a car correctly, it still doesn't mean the motor is going to hold up.

They can both take a massive 5 psi beating when tuned right though........lol.

D16 rods are so cute and tiny though :lol:

OMG 5psi no traction lol
