soon to be powered by twin boeing gas turbine engines!!!!

 

yeah J, we need to figure out my mysterious loss of vacumme, lol.

 

Hey Snw...you got a thread that has everything you have done to your 260??

 

umm, sorta? lol, i think.... why?

 

he hasnt even begun to work on it......

 

Just curious as to what you have done to your Z...and do you have some good pics of your 260?

Maybe not...but she moves good

 

Get it to a 1/4 track!

 

hey nismo, did you ever get your zx to utah?

 

Yeah, about a week after MSA I got it transported home for $390. She's stuffed in the back of my garage for now.

 

hopefully gonna become even faster??

 

Indeed. "Upgraded" cam and rockers. Gotta put together my 318ti & then work on the Z.

 

why not put an "upgraded" head while your at it?

 

eh? It's already got one... shaved .020, 3 angle valve grind, new springs, MLS headgasket....

 

no porting, no bigger ss valves????

 

ummm, right now ive had a few 260 LIVES! threads at the time turned out to just be diesiling though and the paint job needs a lil work no good pics my friend took some but the *** hat hasnt sent em to me, ill make new thread for it some time when i get those pics. but right now its solve my mysterious gigantic vacumme leak, then paint, then mods. then i dont know what, im considering selling her before teh winter unless i can get my garage spot back.

 

you ever figure oot what wrong pick?

 

Naw... for the time, effort, money, supplies to port, and little gain, it's not really worth it to me (not for the L28ET anyway). And they are new valves, but stock size I believe... the machine shop never said anything to me about going oversized.

After much pondering, I think now that it was crappy bad oil. Even tho the oil only had a couple hundred miles on it, it had sat for almost a year in the car, through winter, summer, winter... I'm going to change the cam / rockers & use synthetic oil to see if that will solve the lube prob.

 

I hope you plan to use a good quality non synthetic oil to break in the new stuff - for at least 500 miles then switch to synthetic...do it right man...do it right.

 

alright barbie, i could get the cable out, but the car is just a little box of metal now, but i still have the glove box chingas...

 

i dont think there is a much of a breakin in period for cams its probably a good idea to take it easy for a bit but im pretty positive you can use synthetic right away, and why were you using synthetic in teh first place? i love that stuff

 

new cams require 20 minutes at 2500 rpm, non synthetic, then one oil change with non-synthetic. then do what ever you want. for good measure put a new oil pump on, its kinda security.

 

Why was or wasn't I using synthetic??? I didn't have synthetic in it because the motor had about 2500 miles on it. You don't use synthetic to break in a motor.

Yeah, a couple fresh oil changes will hopefully clean out all the freaking metal shavings from my cam lobe!

 

well i didnt know that, lol. i thought 1k miles was an engine break in period though.... or is that 3k...... hmmmm..... and synthetic is cool and all but once i switched to it my timing seal leaks now

 

Engine break in is usually 500-1000 miles. Synthetic is molecularly thinner than organic (normal) oil. If you put synthetic in a motor that's been using traditional it's whole life, things will leak as the gaps between metals & seals has actually been wider for the thicker oil.
