ARP Rod Bolts
Bumble - 17/9/13 at 09:54 AM

Hi All,

I've done a search on here on this subject and opinion appears divided on the benefit of fitting ARP Rod bolts.
I have just acquired for a very good price, a Ford remanufactured 2.0 Silvertop Zetec that I plan on fitting over the winter as small end bearings are noisy from cold on my current 2.0 Silvertop - repair cost vs new engine cost = nothing in it!!

I obviously have to pull the sump off to fit the shortened one on my current engine and am not sure whether to fit ARP bolts or not. Car is predominantly used for "spirited" road use with odd track day.

I've read the fitting instructions from ARP website and it recommends re-circling rod ends after fitting new bolts. Is this really necessary and how easy are they to fit? Can't decide whether to ARP or just stick with Mr. Fords Rod bolts already fitted.

Thanks,
Matt

Fitted them to my black top the other week, just to be safe, not because I plan on using the extra 500-1000 extra revs they may safely give, but if I accidently stray in to that band, for the sake of £40-50 it felt a like a cheap safety buffer.
On the blacktop they bolted straight to it with no concerns, there was already a taper on the cap and the existing bolts.
Not sure if its just older zetecs that need the taper added. But from what ive read, its not hard to use a tapered drill bit to add a small taper to them, it doesnt need to be a machining job.

I used a wood-countersink bit to make the necessary taper on my old XE, was fine for 12,000 miles.

Do the fly wheel at the same time, for the same reasons

Is it common for them to fail?

Unless your planning to rev the engine past 7200 there is no need to fit arp bolts.

If your engine is stock it won't pull much past 6000 anyway

I wondered who bought it . I was about to bid the start price as you did but you beat me to it lol

Current engine is std apart from R6 TB injectors, free flow ss exhaust, Megasquirt and lightweight flywheel....easy to rev past 7200 rpm!!

When I rebuilt mine I just put in new Ford bolts and torqued them carefully as per instructions.

I think new standards bolts are fine up to 7k on a regular basis.

And what is the correct torque for standart Ford con rod bolts in Blacktop?

whitestu - 19/9/13 at 03:24 PM

My blacktop has been fine on standard bolts using 7250 as a limit, but it has accidentally been much higher than this [8200 iirc] and has survived.
