Thread: Confused about flywheel

Hi I have a B15 sentra with a SR20VE swap and B15 tranny.

I need a new flywheel, currently the one I have was a wolftechnologies one. I really don't want to spend another $500 on another flywheel but I'm not sure what exactly will fit.

Will this fit?

I also need the bolts for the flywheel, does ARP sell them? I see listings for the DET but from what I understand the DE and DET bolts are different size. I assume the VE bolts are the same as the DE bolts?

Any other inexpensive options? It seems there is no inexpensive cast flywheel, I don't care if it is lightweight or heavy to be honest I just want a working one.

Anyone want to sell me an inexpensive used OEM one? Thanks!

yes u need the 108 tooth one so you wont get a check engine light for an extra tooth. also any oem sr20 flywheel will work, they all have the correct about of teeth so the crank sensor sees what it needs to see. thats a good price tbh. as far as i believe arp does make bolt but talk to greg a gspec.com and he will be able to get you some. also make sure u use red loctite on them when installing them and a 6 point socket not 12

Don't the JWT flywheels have a replaceable surface like the Fidanzas...?

Do not buy XTD, it is junk.
And the RWD ARP bolts do work as far as I know.
The funny thing is, ARP does not actually even make an SR20-specific flywheel bolt kit. The kit being sold is ARP part number 254-2801, which is for some Ford V8 motor that just so happens to work (the bolts are actually 1mm longer). Aftermarket parts stores call it an SR20 kit and resell it, sometimes at a markup.

So where can I get an OEM flywheel replacement? Nissan lists the ring gear and insert as separate parts. Can I use the ring gear from my jwt? The holes in my jwt are foobared so I can't use it.

Okay so I'll order bolts ARP part number 254-2801 they seem cheaper as a Ford part than Nissan (like you say, mark up for the JDM crowd).

Now just the flywheel.

Oddly when I look at parts stores they only have the insert / shim (the friction part).

Hi all. the ARP studs are out of stock locally but I can get these locally http://www.summitracing.com/parts/arp-156-2801

It's a new part number, pack of 8. Same thread and pitch and size. The only difference is the under head length. The old part number is 1 inch or 25.4mm the new one is 0.975 or 24.75mm

Think it will matter?

EDIT: answering my own question, I see above the old part was 1mm longer than stock so these are identical!
