Whaddya think about these Brent?? The only issue I am somewhat worried about is it's resilience to heat (didn't find any grade 8 bolts/nuts). No washers as of yet

My issue exactly! I just bought some head flange bolts (and nuts for stud removal) from Home Depot. I will post pictures in a few and let me know if you think they may work out.


I was able to get the nuts on my old protech manifold, I think I did use smaller the stock ones though. I think those two are the only ones that are much worse then GTiR one.

yeah on these turbo manifolds stuff gets really tight and the smaller nuts will definitely help. I had the extended enjuki racing ones and loved them but some manifolds wont work with them due to length.

Thanks for the recommendation guys!! When I make my trip to the hardware store next, I will pick up a set and see how they work

Also, I think I may have came up with another solution. Now I DID end up purchasing a complete stud, nut and washer kit from Greg which should be here this week

Regardless here is what I came up with:

I basically ground down the washer on one corner to fit over the raised portion of the manifold runner. Seems to work just fine. I will know for sure on Friday once I get the OEM in and grind them down. In the meantime, here are pics. Let me know your opinions

def wont hurt at all still gives you enough surface area (more than not having one on there)

I like that. Cody used to shave down stock washers and stuff all the time to fit around welds and things. That should work fine.

Ohh that's right, I remember having to do the same with that log (I'm assuming you bought it from keo?).

Which cars came with washers on the exhaust manifold side? I've only owned 99+ SR20's and all of them had exhaust nuts that were huge and no washers.

My two 99 cars had them. Maybe it is a roller rocker thing to not have the big washers.

No, not this manifold. This setup was purchased brand new from Protech back in the day. The engine is a 98 SR20 for reference

Just a quick update:

I shaved down 3 of the total 8 washers and so far so good. It looks I am getting proper surface area contact between the bolts and the surface of the washer. I also tightened down the bolts in a star fashion and no leaks to report so far. Once I am able to drive the car again, I will check back after I do a 100-200 mile loop to see how they are sealing.
