im doing a All motor b18c1 wit b16a head. I was tighting the head bolts to the book, an i stripped out the block!!! then had it fixed at a local shop, pent to put in back together an it happen again!!

Question is, what head bolts do i use? Im useing the b16a ones..... maybe the wrong ones?


Please, lil info will help!

You can e-mail me also, monkeyboy313@hotmail.com

 

i have the same setup i bought gsr head bolts i think although it was a while ago so im not sure. what torque spec are u using?

 

There's nothing to it. You use the coresponding botls to whatever head you are using.

For the PR3 (B16A), use PR3 bolts, they fit perfectly.

That is wrong. B16a bolts are too short. That is the reason you stripped the headbolts.

Use B18C 1 or 5 head bolts.

Definitely not. That's how misinformation is spread and people continue to tear out threads.

Use the studs for what the block is. B16's are about 3/4 of an inch too short to use in a gsr/ls block and put too much stress on the threads they can reach.

 

Jay,

thanks for 2nd'ing what I said. The mis-information has got to stop.

Oh yeah, nice car and a nice build.

 

If thats the case i'm sorry. I have a B16A, B16B and a B18C5, thought they were all the same, including the B16B and B18C5 ones which come with the P72 block.

I'm suprised to hear that.

 

B16B and B18C5 are the same block. They are both taller that the B16A.

Ditto. I was always told the same thing and believed it until I was assembling a motor and looking at my headstuds. I had a set of GSR's and B16's from GE and they were different lengths so I started researching it and found the differences.

It's been spread forever and a lot of very intelligent guys still believe they are the same but it's sheer luck they haven't found out the hard way I believe.

 

Good to know, thanks for the heads up

 

Yep.

If it's a B18c, the head bolts are 6 7/8" long, B16a are 6 1/2" long. That's total length from the very top of the bolt to the bottom.

 

Mis-information sucks.

 

ive re-used gsr headbolts with no problem. and i have done 2 poormans builds

 

yea!
me too

Just because YOU have done it and it worked out doesn't mean it SHOULD be done. I reused a set of B16 headbolts 4 times once, motor still runs but knowing now what I didn't know then about properly measuring them for stretch, I wouldn't do it again.

 

why are you using B16 head instead of GSR? Im assuming that you had GSR head before. This cause you alot of headache and GSR head is better.

 

so much misinformation over the internet.... You need to use GSR head bolts as established earlier in this thread. As for what head is better... im not even going to get into it.

 

thank you all!!!

haha well its solved, now all i got to do is get the old helicoil out of the block, put new one in, an put in my egale head studs in it and i should be hooked up.

Im useing my b16a head b/c my motor is pretty much a type-r motor, 12.1 compression, and thats kinda high an i was told that the b16a head will keep me in safe zone for higher rev. If that is false info, please correct me! lol its not together yet.

My motor is got

egale oil pump, water pump, griddle, p72 rods, 12.1 compression pistions, all ina b18c1 block! bought it from someone who was parting out his street car.

Anyone got any good ideas on takein out the old helicoil?

thanks again everyone for all your help.

those p72 pistons must have massize carbon buildup on it, to be able to get to 12:1 compression...

How on earth did you come up with 12.1:1 compression? What p72 pistons are you using? p72-A0 = USDM b18c1, p72-00 = JDM b18c1. With these pistons, a stock head gasket and no decking or planing of the block or head, stock valvetrain, you'd only be between 9.8-10.3:1 compression roughly. If you were using JDM ITR (p73-00) pistons, you'd only be at 11.1:1 (everything else stock) at best. Your part combinations and number claims just don't add up... do you even know what you bought or did you just take someone else's word for it?

take it to a good machine shop and have them use a time sert they are stronger than helicoil's imo.

milling the half an inch

 

the motor i bought was rebuilt with domed type-r pistions. Not b18c1 but i think ither aftermarket, or typeR.
