Can someone give me the part number for the correct Timesert kit? Just want to make sure i get the right ones.
Thanks

Bump to see if you'd purchased a kit yet.

Why not a Helicoil?
That's what I'm doing for my rebuild.
My machinist had better luck with them over timeserts.

In my opinion helicoils suck. Time certs are a permanent fix. The I have done countless Honda blocks with time certs over the years and have nothing but success. you will want to get the complete Honda kit for b series blocks to do the c30/c32. Do not try and do this with out this kit you will ruin your block.
The machine shop that is building my engine has been in business for 40+ years.
he's re-worked engines with timeserts that failed with Helicoils and never had a failure.
He warranties his engine work and wouldn't but on timeserts.
Helicoils are made from Stainless...Bad when combined with Alluminium.
anyway, still after the correct timesert part number or length.

I dont know if mike is gonna reply... but i'll speak for him.. hes correct
the b series blocks were designed at the same time the c30 was.. many b-series parts work on the nsx motors
Ok, thanks. Can't seem to get these in Australia so i want to be sure i get the right kit.
I called Timesert and they tech support guy there said that they have both SS and steel Timeserts.
Helicoils are much more exotic in their offerings:
HeliCoil 304 Stainless Steel Inserts
•Standard, general purpose material
•Stocked in most sizes
•Ideal for original equipment applications, repair, and overhaul
•Moderate corrosion resistance
HeliCoil Inconel X-750 Inserts
•Used in areas exposed to high temperatures
•Typical uses: gas turbine engines, nuclear applications, well drilling
•Non-magnetic
•High corrosion resistance
HeliCoil Phosphor Bronze Inserts
•Ideal for salt water applications
•Non-magnetic
•Excellent electrical conductivity
•High corrosion resistance
HeliCoil Nitronic 60 Inserts
•Manufactured from a special corrosion resistant stainless steel material that is provides superb
galling resistance as well as wear resistance
•Compatible with stainless steel screws
•Ideal for use in vacuum environments
•Requires no additional coatings or platings, hence making them ideal for environments where
contamination is a concern
•Particle free
•Non-magnetic
•Moderate corrosion resistance
HeliCoil Titanium Inserts
•Superior strength-to-weight ratio, ideal for applications where weight reduction is a significant
concern
•Excellent low temperature stability. Their low coefficient of thermal expansion and increased
material stability makes them suitable for use in satellites and applications where inserts must
withstand sub-zero to 600°F temperatures.
•Non-magnetic
•High corrosion resistance
HeliCoil Screw Thread Insert Coatings & Platings:
Dry Film Lubricant (Mollylube)
•Provides additional lubrication in high friction applications
•High temperature resistance (400ºF)
•Highly recommended with HeliCoil Screw-Lock Inserts
•Mildly corrosion resistant
•Colour : grey
Cadmium Plating
•Provides high corrosion resistance
•Plating provides lubrication, preventing galling during insert installation
•Colour : iridescent yellow (HeliCoil Free Running Inserts), olive drab (HeliCoil Screw Lock Inserts)
Primer Free (Heli-Guard)
•Designed for use in aluminum and magnesium applications, HeliCoil Primer Free Inserts are
manufactured to to meet all relevant Military or Metric Aerospace standards and are coated with a
unique resin bonded fluoropolymer coating . This coating forms the barrier between the HeliCoil
Primer Free Insert and the parent material, greatly reducing & preventing galvanic corrosion
•Eliminates need for zinc primers
•Eliminates locking torque issues associated with primers
•Improves installation productivity
•Provides additional lubrication facilitating insert installation
•Colour : matte black
Silver Plating
•Recommended to reduce galling of threads at high temperatures
•Plating suitable for use in temperatures up to 1200ºF
•Colour : silver white
i stand corrected, didn't know Helicoils came in all these different materials,
Handy to know.

Yes, the kit you want is the 7111.
Any shop that would put helicoils in a motor for headstuds is just asking for trouble.
Helicoils are a one-time quick fix good for small, low torque applications and as already stated timeserts are permanent.
BTW - I just want to be sure that nobody is installing helicoils just to try making the threads stronger - because they won't.

Then explain to me why my friends that works at both Travis and Moffett AFB use Helicoils for repairing military Helicopters like this:
TimeSerts are the only thing to use in your NSX block, they even make a Big TimeSerts kit to fix your block when the Helicoils fail (and they do allot). Please do not waste your time doing Helicoils even though it is the cheaper way to go. Cheers, Shad
Considering the topic, I'm curious about the need for these. Have there been that many OEM thread failures? If so, I really don't read about them that much(ever?) on this forum.
Not many OEM Thread failures when using stock head bolts (stock head bolts are a stretch type). But if you have had the heads on and off a couple times, motor is higher in mileage or have converted to the ARP studs and nuts the OEM aluminum threads in the block become weak and fail. Cheers, Shad
Had a thread failure or you did the install as a precautionary measure?
I'm looking at buying that kit for mine. The local machinists I've tried don't have the special tools....
Anyways, I've read the standard Timeserts with the 7111 kit are carbon steel. They also offer stainless steel timeserts. I take it we should use the carbon steel ones?
Thanks,
Dave

Thanks again.
$385 shipped with a free flashlight! Just need to buy some more Timeserts:

Nevermind, the cheapest I can find now is $410 for the kit.
At this point in my build and cash outlay, I'd rather not purchase a kit for my machinist to use one time. He wouldn't have use for it either so he doesn't want to make the investment....
Would anybody that had to purchase this kit consider renting it to me please? I have no problem with a rental fee and a refundable tool deposit once you get it back from me.
The only issue I see is how long it has already taken my machinist. However, I think he's about ready to fully devote time to my engine, so I would probably need it a total of three weeks.
Thanks in advance!

So do you guys torque the heads up tighter with the timeserts or stick with what ARP says.
Rob alluded to a higher torque in this post:
http://www.nsxprime.com/threads/1477195
But he doesn't get on here much anymore and I don't have another way to contact him and ask what he used.
So, I'm going to follow Shad's recommendation in this thread after I get the block time-serted:
