Thread: sr20ve head on usde bottom

Post #159 Page 8. That guy was using det pistons, ve head, n1 cams..

If you're saying its possible on a de, than this guy must've got his timing way wrong when putting the cams in or something...

Additionally SR16 cams+boost on stock DE bottom end is fine also.

valve springs? how high do you rev it on a regular basis

You ever pull the head? Money says you got damage or cam timing is wrong.

Do a re-fresh and snotch it..... i got a set of DE pistons hitted in the exh side... i was using normal cams....

Good lord,what gaskets are you guys using. And are you guys getting these heads resurfaced and if so how much is being taken off.
the only time I have smacked exhaust valves was when I over revved it past 9000 Rpms on a misshift and that was on 20v pistons.Eventually the misshift did some damage to the block and swapped it out for a de bottom end.
I also had that same Head cut 3-4 times in the past and while testing the motor i went +5-5 on de pistons and i had an idea it touched just by how the motor sounded when it switched over.when i removed the head I noticed marks. Other than that I have yet to see any other smack with the cams straight up or with minimal advance or retarding.
I've done 10+de/ve swaps and only had one of my own personal motors touch due to the above events.
I don't wish to steer anyone in the wrong direction but I have my results and conclusions.

De/ve revving to 8300 Rpms. Stock head bolts felpro paper gasket.

De/ve stock head bolts felpro gasket.
De/ve

G20 de/ve

Back in 09' I am still running the same head now

I have more vids of cars with swaps but they cannot be posted on here.

You answered it yourself,mAterial taken off the deck of the block and the head.

Yeah I have. Everything is fine.
