I have a gsr head now and a golden eagle lsvtec kit and some gsr arp head studs ready to be put together but my bottom end has to stay stock for now
1. i have arp rod bolts and is there any way to put them on without pulling the motor apart??? can i just take off the oil pan and replace them that way?????
2. what ecu is good to use do i have to get a chipped p28?? cuz all i hear about them is they run hella rich.

 

bump i need some help out guys

 

1. you cannot just take the oil pan off, and replace the rod bolts... you must take your rods/pistons out and bring them to a machine shop so they can press out the old ones, and resize them for the ARP's..

2. if your going to run the gsR intake mani, then use the p72 ecu, or if you plan on buying a skunk mani, or AEBS, etc.. then use the p28 ecu.... i hope that helps mayn..

 

damn thats more money for a rebuild **** thanks man

 

what?? you can put rod bolts in by removing the oil pan (the crank has to be turned, oil vent has to be removed, and youll need a long torque wrench, but its possible).

For ecu, which one do you have? VAFC is a good option, but U'll want to go to a dyno to tune it.

 

ok now im confused ive got 2 opinions can i or cant i anyone else????

 

to use after market rod bolts on stock rods, you need to get the old rod bolts pressed out of the stock rods, and have the new ARP's machined in the stock rods.

Some people don't bother reading the entire thread and just post stupid nonsense that confuses people.

Yes, you have to disassemble your motor and take everything out to do this.

 

umm, what rod bolts have to be pressed out again? not stock b-series ones, because they are held together with a bolt and a nut.

And if ARPs needed to be machined in, then why would they have different apps for different set ups?

No ignorant replies necessary.

Yes, it can be done, and yes it is a pain in the ***. But a hell of a lot better than having your motor tore apart, and put back together, just to rod bolts installed.

 

Ignorance is bliss my friend... but if you think you don't have to get the rods machined for the new bolts go ahead and try it... and see what happens.

 

Dude if ignorance were bliss, you'd be orgasmic.

It doesn't make sense to machine stock rods to fit arp rod bolts. That means they'd have to rethread the rod, and that would weaken it at high rpms, which would completely defeat the purpose of getting them in the first place.

The big end of the rods have to be resized to fit the new bolts and for it to work properly.... I wish it were that easy to just drop them in... but it isn't...

It doesn't cost that much, maybe 50 bucks...

And I don't care for the comments I'm just trying to tell you what needs to be done.

 

They have to go to a machine shop. I have 2 sets there right now.

 

Ok ok I stand corrected......mine was all hypothetical, maybe I got carried away a lil......but at least i admit when im wrong!!

*edit*, not really. ARPs will fit into stock rods, hence the different apps available.

So bottom line, it's possible.

u need arp rod bolts for a ls part num 208-6001 cost 35 @ lighting motorsports ht special i bought some u u go 2 cheap it will cost u later

 

damn thanks for the feedback guys i guess ill have to go to my local machine shop and see if it can be done still in the car but i do agree with the fact that it is ****** retarded that u have to rip the block apart to replace rod bolts maybe i should just call ARP themselves and see what they say

 

your have to take the rods and pistons out to put the bolts on
you have to take the rods to a machine shop to have the rods resized for the new bolts
they dont really need to be presed out anyone can get the bolts out yourself but you do have to get the rods resized which will run you about $50
and since its out there is really no point in running the pr4 pistons
if you low on cash just throw some pr3 pistons for a cool 11.5 cr and you all good
and since the rods are out you also might as weel renotch the rods to run gsr/itr rod bearings

ARP comes in 2 different applications... 8mm and 9mm .. you want the 8mm.. the rod does HAVE to be resized forr the bolts... if you resize the rods for the bolts you should have the bottom end balanced to do things right so nothing is thrown off by the resizing... BOTTOM LINE IS arp bolts are not bolt and go... like previously stated ... if you want to do it go ahead but you will be dissappointed when it doesnt work

 

i dont know where u are getting your info from but stock rod bolts do not have to be pressed outand there is no mod to get the arp rod bolts to fit i took my stock rod bolts out and put the arp rod bolts in no problem and my ls/vtec is at 8500 daily and 12'000 miles later not one problem so the answer to your question in NO there is no machine work to make them fit and NO u dont have to take them some where to get them pressed in and out its not hard at all do it yourself and save your money u can go to summitracing .com and order the rod bolts like i did and put them in yourself

your a dumb ***
yes you do need to get the rods resized anytime you change the rod bolts

 

ok dick face im just making all this up and il really did have to get them pressed NOT!!!!
listen here **** face im a tech at honda and i built this motor from a bare block so i think i know what i did to build this motor and the only machine work i had to get done was the block shaved ,bored ,honed,and the head shaved and proted and polished everything else i did at in my stallso dont ******* tell me what i did or didnt do maybe one need to research your info and why would arp sell rod bolts for that app. that needs to be resized also its been a while but i do believe the part number is #208-6001

 

haha i wouldnt want to drive the car with the bolts not resized and done half ***... probably with pr4 pistons 2 haha

 

thats pretty funny for somebody who doesnt know alot about this subject i have a little more than 12,000 miles on this daily driven car which sees 8500+ daily and there are 2 other techs at my dealership that have done the same and both have a solid 20,000 miles + with not one problem but what ever u can take the word of somebody (WHO HAS HEARD) or somebody who does this succesfully for a living at a honda dealership its your choice

just a note: they are pr3 81.25 with ls rods arp rod bolts(direct fit) the ony thing i had to press off then on were the pistons

 

did you even build this engine yourself.....pr3 and p30 pistons are a direct fit onto ls rods... itr and ctr pistons need modification... i havent heard.. this is from experience..im not here to argue.. just so other people do it the right way

 

SHOOOOOOOOSHHHHH!

JESUS..ALL THIS BICKERING.

listen..heres the deal, not to sound like a dick, but these are the facts.

1. LS ROD BOLTS DO NOT HAVE TO BE "PRESSED OFF", YOU CAN TAP THEM OUT.

2. ARP BOLTS DO NOT HAVE TO BE "PRESSED IN", THEY CAN BE TAPPED IN.

3. IT IS NOT "NECESSARY" TO RESIZE THE BIG END WHEN INSTALLING BOLTS.

4. IT IS A VERY, VERY GOOD IDEA TO RESIZE THE BIG END WHEN INSTALLING ARP BOLTS BECAUSE WHEN TORQUED, THE BIG END WILL BECOME SLIGHTLY OUT OF ROUND.

5. I KNOW THIS BECAUSE I HAVE DONE IT BOTH WAYS.
