Just wondering who's built their bottom end up enough to use ARP main studs?!
Im in desperate need of the partnumbers, or even a company you got them thru. I don't want to use stock replacement main bolts
I know there's one particular org member who had main caps custom made, and he had ARP main's, iirc.
please, i would greatly appreciate any info you have for me.
thanks
Steve
I'm not done yet, but my 2200 will have ARP head studs, mains and rod bolts for sure. If you are building a fresh bottom end, ARP is the way to go.
I was a retard, and now I'm permanently banned.
go to www.jtuners.com they sell arp mains
and JBP sells the ARP head studs.

As of right now ARP doesnt make a Main stud kit for the LN2 engine, just the head stud kit.
I am going to send my stock main bolts to JTuners and they are suppose to work with ARP and have a set of studs made.

Mike, when is this all going to happen?
Believe me guys, I obviously WOULD go with ARP mains if they made them in that size/length.
I have been around for long enough to know where to go for headstuds, infact they're supposedly in the mail! (from jtuners)
the whole rotating assembly will be balanced as well.
I hate talking about my project.
lowfire (chris) had a set of ARP mains, I was hoping he was going to read this.
He also had custom main caps made, and that's probably where he gained the extra length to find bolts that fit.
gah, I dont need this problem right now
At this point, im not exactly sure, may need to call ARP directly and tell them what you need, if you can give them the dimensions of the stock bolts then im sure they can make you something that will work, they do custom jobs, just cost more.
Id like to know where lowfire got the main caps from??

I sent him a message yesterday but hasn't gotten back to me.
I can only imagine what custom mains cost!!

Yeah i was thinking the same thing. BUt you would only really need the 2 center mains that would make the bottom end alot stronger, I wonder if the LN2 main caps are similiar to SBC caps at all??

well my block is at an 'sbc' specialist machine shop... (i use the term lightly)
But they have been in touch with ARP, and that combined with all the different blocks they have sitting there. They haven't been able to match a set up
apparently they dont make that particular length/pitch`
Well im pretty sure that the stock bolts are an 11mm, probably an 11mm x 1.50 or 1.75 thread pitch??

Hey guys
Yeah, mine are made for my billet caps so I don't think those dimensions would do any good for ya
Sorry I can't be of more help, the billets are a tad bigger than stock
................Which car will hit 400 whp first???................
Where did you get the billet caps and main studs from?? What did they cost you if you dont mind me asking?
Did you get all 4 billet cpas or just the center 2?
Got any pics you can post of them??

damn, stevefire is SOL
thanks for getting back to us thou chris.
If you have pics to post of what you did, that'd be awesome.
I'm wondering if we could get billet spacers made up to allow our blocks to fit the V8 main studs?
I know we have quite a bit of clearance between the oil pan and the caps.. so that way really isn't much of an issue.
I'm going to talk to the machine shop tomorrow and see what we could possibly do.
Well i called Pro Gram Enginering today and asl them if they have ever done anything with the LN2 2.2 engine and they said no.
So i tola them that i was looking to get a set of billet main caps made and they of course would need my block and stock main caps for mock up, and if i sent them the block now, with a 50% deposit they could have it done by around the 3rd week of January.
Total cost 750 to 800 bucks plus the cost of shipping them the block.
Now that would be a 2 bolt front cap, and a billet wet sump rar cap that woud also be a 2 bolt like the stock caps, and would be a splayed 4 bolt on the center 3 main caps. And that doesnt include them drilliing and tapping the block for the center splayed bolts or line boring the new caps either or the cost of a custom ARP main Stud Kit.
I was on the phone with ARP about the main stud kit and they faxed me a calculation sheet to see all the dimensions of the stock block and main caps to see if they have any in stock kits that will work, or if a full custom kit is needed.
Ill get back to you all with those results.

Yeah, these are just about the only thing left on my bottom end 'to do' list (don't think there is really anything else I could do other than machining...). Anyway, I've been giving JTuners 'subtle' hints that they need to have these produced, and they said they've been having problems with ARP and weren't sure if they were planning on doing them or not.
Also, with regard to billet mains: I thought about having them done, but I can't get over the possibility of different rates of thermal expansion between them and the block (steel vs iron...same material basically, but different %Fe, which would make a difference). I dunno, that's just one area I wouldn't want to have to worry about materials differences.

The Billet steel main caps will not casue any isues when run with a stock cast iron block, its been done for years and years on SBC and other motors and has proven way more reliable than the stock cast iron caps.
With the billet caps, main studs and forged rods and pistons the only weak link would be the crank, and with a turbo motor the boost comes on smooth enough to make lots of power before you have to worry about the crank breaking.
but large amounts of N2O seem to be harder on the engine so i dont think it would last as long, plus when the crank did break, the entire motor would be junk, it woudl take the block and everything with it most likely.
I want to have some made, but will probably only have the 3 center splayed bolt caps made, it will be cheaper and the biller rear and front cap really isnt needed.

well apparently the stock bolts on the LN2's aren't 'torque to yield' so they are reuseable.
I just got all my machining finished, just waiting for them to hone out the small end bushing on my rods and pin fit the pistons.
Got the align hone done with the stock bolts, unless we find a kit or something close within the next month or so, I'll be using stockers... *zips up the flame suit*
sorry but there's no real way around it unless I want to spend that much on billet mains.
has anyone else had their crank balanced? Apparently it didn't take very much for them to balance it... weird.

Yeah, with internally balanced cranks, it shouldn't take much, as not much can change once it leaves the assembly line, right?
Did you over-bore at all? Any metal treatment, oiling work, o-ring, balancing? If so, how much did this stuff run you? (I'd hate to take my engine down to the machine shop and come up short on cash
)
fortune cookie say:

didn't o ring the block as Im hoping jtuners comes out with the MLS HG's soon. The oil gallery holes were chamfered, and no real metal treatment was done.
I haven't gotten a grand total, but my estimate was for less then $600cdn.
that includes;
prep wash
overbore (+.020")
crank grind (+.010")
balanced crank
pin fit (piston)
rod hone (small end)
align hone
ring gap
cam bearing change
and I believe it comes with main and rod bearings...
I did get a deal because I know the machinist at the shop.. I hope that helps. I cant think of what all else I got done (if I've missed anything I'll let you know)
Cool, thanks, that's about what I would expect (assuming you didn't get a HUGE discount
)
Obviously you're in the boost world...and it looks like you may be the first 2.2L done with a full boost build (that's still running, unless I'm forgetting someone, which I probably am)...what are your goals for the setup?

Well they are available now, you can orer them on there website, they have them in stock for N/A and Boosted applications, and i got mine in the mail the other day and it looks pretty sweet. Should be good to go for lots of boost.
BTW: Mine is the boosted version.
Heres a pic for you.

I have a 96, and I thought the 2200's were different!?
Hell if they're not I'll order one up right now.
plans for my build? To daily drive it with boost, and successfully run a 96 2.2 with a standalone. (not sure if anyones done that 'yet')
I know lowfire has an insane build on the way, and he will no doubt be hard to keep up with, but he's not finished yet
. He is also going to be running a multec or AEM (can't remember what)
I don't have any hp goals in mind, nor do I have any 1/4 mile times in mind. I want to be able to romp on it whenever I want and hit 15lbs consistently...
I've got a Haltech E6GMX, hopefully it'll be able to idle my 150pph injectors.
Also doing a top feed conversion w/ aeromotive AFPR and 2.3HO fuel rail (hopefully)
