Lots of hot, cold cycles affects all of the studs / bolts on engine. Add a tight cambelt to weakened tensioner bolt = snap. Exhaust manifold studs are more common due to they experience more heat.

ahhhhh yessss that makes sense! Heat, ultimate pain in the ass.. Good call Skym.

What spec are those kelford cams and did they require any head machining? I wanted some longer duration than 264.

[Skym]

Look on Kelford cams website -

Yep, reused the stock old tensioner bolt never doing that again.
Spec on cams, stock lift, 270 duration, no machining of head required. Although I did get a three angle valve job .

I replaced all the exhaust manifold studs with arp hardware when I did the first rebuild.

With stock lift, did Kelford regrind stock cams???

[BenOswald]

Nope, brand new product. I was specifically looking for sftop in cam, didn't have the money to build my head, kelford offered the best service and most aggressive duration, while still staying working stock spec limits. Which I am very happy with and highly recommend these guys. They're from NZ, they had my cams at my door within a week of placing the order too, very high quality, very old shop(they've been inthe business for years) love em.

I have a second rb25 I will be building in the next year or two, which will have fully built head, with big lift big duration cams, to help achieve my 650hp goal for it. But the motor in the car now, I want to keep around 400-450whp. To keep it somewhat docile. Brrrrat brrrap brrrapp braaaaaapbrapbrap braaap, shift, brapp, *squeal,*smoke,*flames. love.

Cool.

[BenOswald]

[BenOswald]

Decided that I will be doing a GT4088 top mount set up,on th spare motor for the monster set up.

[Supraclean]

WIN! What manifold are you going with? Please say 6boost or 'something custom or badass!

[BenOswald]

Something precision and quality for sure! I really want full race, but you know.....$$$$

[BenOswald]

UPDATE: Fixed the electrical, was due to bad engine ground. Compression tested and i have zero compression. Bent Valves. So i dug out my spare head and valvetrain and am prepping to swap it over.
