I've ran Supertech all season at over 900hp and over 10,000rpm, not one issue, must be crap eh?Supertech are cheap crap I wouldn't use any thing made by them, I've seen snapped valve springs and retainers. I would imagine there valves and guides should be ok
That is some statement you made there "cheap crap".. I am waiting to hear from any of the tuners who have used their parts in their high powered engines.. I want to get it right first time and not mess about about. Tomei is my first choice but I am considering Supertech if they are as good why not?Supertech are cheap crap I wouldn't use any thing made by them, I've seen snapped valve springs and retainers.

I would go for tomie with out a doubt, ask Ian at clockwise motion who builds 24hr race engines he has seen it time and time again with supertech. I wouldn't fancy using there parts but on most engines for road short track use they will probly be fine. I would rather stick with standard nissan parts myself proven partsThat is some statement you made there "cheap crap"..

Lol used supertech in all my heads and never had a problem and there parts are not made in china.Supertech are cheap crap I wouldn't use any thing made by them, I've seen snapped valve springs and retainers. I would imagine there valves and guides should be ok
I'm just going by what Ian told me/showed me and made me think I wouldn't want them in my engines, he did go a bit far with it but every engine he built was proven. We all have our own opinions and what we've seen and what has worked in the past. For me I wouldn't feel comftable risking itLol used supertech in all my heads and never had a problem and there parts are not made in china.
