Hello all I am thinking of changing the bolts in my engine bay to titanium, thing is I can't find anywhere online the size or kind of bolts used in our engine bay and number of them, can anyone please advise on this matter.

Thank you for sharing, I came across several sites, but I'm not sure which sizes and quantity needed for our cars, if you can kindly chime in

Here's my engine bay: https://www.clublexus.com/forums/bui...l#post11169970

I have since then switched to ChasingJs' hardware though.

Quality on the ChasingJS' are better.

No I'm not serious you are not going to replace every bolt in the engine bay.

So all the 10mm socket bolts are M6-1.0

Most of the bolts/nuts in the engine bay are M6x1.0mm and M8x1.25mm. A lot of them you can choose to replace with shorter ones (bolts) to save some weight. The bolts and nuts that use 10mm socket are the M6 size and the ones that use 12mm socket are the M8. The shock tower nuts are M10x1.25. Unfortunately, there isn't a kit that has all the bolts and nuts made for our specific engine bay. Here're my main sources of titanium fasteners, and I've replaced a lot of them all through out the car:

Racetech Titanium
Pro Bolts
MetteC
Ti64

The 4 small screws on the GruppeM filter housing cover are M4x.70mmx12mm.

HTH.
