what are some good bolts and gaskets to get for the pacesetter headers? i havent driven it more than 3000 miles and one of the bolts are gone, 4 loose, and the gaskets are blown out. what ideas?

86BLUEBIRD

summit sell stage 8 locking header bolts. its like 40 bux. u can get felpro manifold gaskets from any parts store for like 5 or 6 bux

87blueracr

where, cause i tried advance, they didn't have the gasket. i decided to use grade 8 bolts for mine with a lil high temp loctite

86BLUEBIRD

u hafta ask for the exhaust manifold gasket. they dont make header gaskets for these cars. u might be able to find header gaskets for s-10 or something but i dont know

87blueracr

oh well too late now, i got 1/8" garlock(high temp, high pressure gasket material) now, i garuntee that stuff won't blow out.

supposibly the gaskets for the 2.8 fiero are better then the camaro and s10 gaskets.

I keep hearing about using LS1 something bolts, dunno.

87blueracr

it is possible, but the 2.8's take the 10X1.25mm bolts. that seems kinda small for a 8 cylinder

87blueracr

they are the wrong size for the 2.8. i measured the threads on the ones i took out the other day 4 times with a standard pitch guage and a metric, they were metric on my car!!!!!!!!!!

86BLUEBIRD

it says its for the 2.8s and thats what is on mine and they work fine. take from that what u will

Header gaskets ARE available for the 2.8...Fel Pro makes them, and they work great. I don't have the part # handy, but will post it later. If your local parts store/speed shop can't get them, call Barnett Performance in Atlanta (800-533-1320) and ask for Chris or Keith.
The Stage 8 bolts (LS1) work well, at least with the PF & E headers. Standard SBC bolts weren't long enough IIRC.

86BLUEBIRD

the only gaskets ive seen from fel pro r listed as exhaust manifold gaskets. this is what they look like.

im gonna start doing some checking around and find header gaskets tomorrow and get some bolts. if i find the part number, ill post it for anyone else w/ headers.

87blueracr

that is kinda funny, the 3/8-16 are close, but not enough to keep from crossthreading them. with my standards of bolt fit, that wouldn't do. i want the correct ones with the correct fit in this case i believe it is a class 2 fit that you are looking for to keep them from backing out, though it may be class 4 fit. i always get the classes of fit mixed up. i guess that i better go and study the machinist's handbook some more before i take my next advancement exam in a year!!!! the difference between the classes of fit is just how much clearance is between the "nut" and the "bolt" or male and female whichever you perfer. i would want the fit to be within .001 for both the female and male major and minor diameter that way as soon as they heat up, they lock where they are and don't move, but unless you get a machine shop to make them for you, you won't get that kind of fit.
when it comes to fasteners, i suggest that everyone who is not a machinist read a copy of the section for fasteners in the machinist's handbook. it will really open your eyes and give you a higher standard on nut and bolt quality.

86BLUEBIRD

for the love of ***. I have the Stage 8 bolts made for the 2.8 on my car with the pacesetters. theyve been on there for over a month and havent budged. They work. what other freakin proof do u need other than that they work

87blueracr

(laughing)
as long as they work and they are the right size, and you are happy with them, you good to go. i was just simply stating what i would use and am using and why. sorry if i made that a little too indepth and long.

RTFC

'87Blueracer, newsflash for you- our entire cars are metric.

You guys need to simply godown to any local performance VW shop and buy some "performance header exhaust gaskets" for a type 1 VW bug engine. They are the same 2-bolt spread pattern per cylinder. The stock VW gaskets are 1 1/4" ports, the performance ones are 1 1/2" ports. Its what I have on my car.

The ones I use are metal on one side and paer element on the other (metal ring goes through though- so no blowouts ever.)
The gasket to the right is part of a Hooker headers gasket made specifically for our cars.

RTFC

Also, our header bolts are an M8x20 bolt. Go to any industrial hardware store and they will have them in stainless steel. Also use some copper antiseize compound on them and re-torque them after you first the motor and warm it up the first time- try to retorque them when the motor is still hot.

87blueracr

yes dean, i know they are, but i always check to make sure because i have found standard bolts on the car before and i know they werent' supposed to be there. cool, now all i gots to do is find a shop around here that sells vee-dub parts and i am good to go with the gaskets. i would rather not use garlock unless i have to.

87blueracr

dean are you calling 20MM the thread pitch or the length?

RTFC

Are you kidding me? I thought you are a machnist specialist in the Navy?
Kid, you keep showing you inexperience. Its the lemgth.

LT1guy

iTrader: (1)

They're not in the regular vehicle gasket listing, they are in the performance gasket catalog. Thats why few regular parts stores will list them.

87blueracr

dean, it is supposed to look like this due to the multiple different thread pitches Major dia.X Thread Pitch X Length. on all technical drawings that you will ever see, you will never see major diameter by length without having the thread pitch inbetween them. the reason for that is that there are about 1,000 combinations of just major diameter and thread pitch(1-4, 1-6, and 1-8 all of which are standard american thread sizes). that is what tells you how to set up the machine. the length (obviously) tells you how long to cut the threads. yes to do it right, you cut them on a thread cutting machine or a lathe. using a tap or die will work for "in a pinch" work, but to make sure that the threads are straight you use a lathe or thread cutting machine(i call it this cause all it really does is hold the stock square to the cutter{wheather single or multiple point})

for the new guys' sake the correct size is M8X1.25X20mm

i just ordered locking header bolts and felpro gaskets through summit, they make the bolts specifically for the 2.8, so we dont need to use some off another vehicle. should have them by this weekend. ill list part numbers and all that when i get them for future reference.

LT1guy

iTrader: (1)

Cool, someone must have told Stage 8 their LS1 bolts would fit. When Redraif's were ordered they weren't yet available.

86BLUEBIRD

they work. those r the ones ive been talking about. do u have the headers already or r u ordering them?

87blueracr

86 blue, i do have the headers already they came in like 2 weeks or so ago. they are just finally getting put on!

86BLUEBIRD

they make a difference. mine rnt setup into true duals(although the guy that put them on said i should go that route) but i noticed a difference. i just used the stage 8 bolts and fel pro manifold gaskets( they looked better than the ones that came with the pacesetters) and havent had any probs there. i had the slip joints welded together but there r still small leaks there and the ball/flange joint on the drivers side leaks so i will get something to fill in there. at some point i will cut the cat off and put in a piece of pipe ther since we dont have any inspection.

87blueracr

86 blue, i don't have the pacesetters, i got the HOOKERS. i figured out how to run dual sides with a h pipe. they a pain to put on the car with the engine still on! especially the driver's side(hurts my hands just thinking about it.

86BLUEBIRD

hopefully for u that intake will flow that much more air. otherwise u will be losing too much pressure and killing ur performance. engines r basically air pumps. if u cant pump in as much air as ur pumping out its all for nothing. if the 350 SBC dont need true duals to push out 400+ hp, this v-6 wont need it to push 200+ like ur going for. bigger is not always better. and as much of a pain in the *** it is going to be(as well as a money pit), u might not get what u expect from it. id say maybe go with a 3" like redraif and the 350 guys, ull probably get better sound and performance than the 5" worth of flow ur gonna be putting on there.

87blueracr

i am droping it to a 2 inch system, not leaving it as 2 1/2 from the collector. word on the street is that dual 2 1/2 flows the same as a 3" system. i don't know how true that is, and i haven't gotten the machinist's handbook out to find airflow through a specified size tube. yes the machinist handbook even has information on stuff like that!
i understand what you are saying with that, i know the size of the tubing that they are using for the intake, and it will push the air through without a doubt.
p.s i am shooting for 300 not 200. 200 is easy with theese engines, i want a challenge that is why i am going for 300.

drdave88

iTrader: (3)

ive got the headers on, got about 3000 miles on them and the bolts worked loose and blew out the gaskets.

87blueracr

uh ho that isn't good, if you don't want to get those studs in the correct size, then just use the bolts that you have been using and put some high temp loctite on them. you could also use a punch and score one of the threads too.

86BLUEBIRD

300 rwhp? unless ur going forced i doubt ull get there. good luck tho.

87blueracr

like i said i like challenges! not forced induction, just a good cam, high compression, a good intake, new rear end gears, headers, and some other internals.

86BLUEBIRD

meant to ask. what ship r u on in the navy?

86BLUEBIRD

dave, after u get them bolted back up with the new gaskets, check the bolts every few days. after driving just retorque them down, even the flange bolts. if u keep noticing them move out, get some hi-temp loctite to seal them in.

my brother spent 4 yrs(drunk) on the arctic(supply ship) as an electrician and mechanic.

87blueracr

yea agreed that is the smart thing to first off, that way you don't have to worry bout them.

87blueracr

not all of us are drunks, the arctic almost hit us a couple of times durring underway replentishment.

86BLUEBIRD

u ever heard of Raytheon? i spent 4 years building cables and harness assemblies for them. alot of DOD stuff

87blueracr

yup, i have. well i guess we better quit jacking this thread, might p**s someone off prety good, if you wanna chat, just email me!

ok locking header bolt kit part number is: stg-6910 $40.99 through summit
fel-pro header gaskets: fpp-1449 $24.39, summit
although it says the gaskets are a 1.25 diameter. our tubes are 1.5. so i may have to shave a lil off.
