Max rpm on my build? yes it's already built
First off I wanted to thank all the people on this forum for supplying me with information and i was not a part of the community much. Now i am lol.
Sorry i hope this is not a dumb question as i am actually very new to this forum.
current mods just to motor and drive train
I just wanted an idea of what my rpm limit should be around....
Rebello built 1.65L b6
supertech +0.5mm 8.8:1 pistons
manly rods
ACL ceramic coated race bearings
port and polish
oversize supertech exhaust valves +1mm
vs-855 valve springs
kia lifters lol
1.8 valve train parts for sustained high rpm
Adaptronic ECU
ARP Everything,, yes the flywheel bolts too.
fadanza 7 ish lbs flywheel
2.5 separated Downpipe
3 inch cat back silverline
2000nb 6 speed
1.8 lsd
i think that's it
Soon to be changed
Greddy turbo kit with td04h
begi downpipe stainless
changed to a
begi s4 manifold
with s15 spec r t28r
custom Rebello downpipe.

I was under the impression that the vs-855 springs that have a 66lb resting rate had a much higher rpm capability vs the 46lb stock... closer to 9k is what some other have done.
Im guessing the 7000 rpm was much sarcasm because stock is 7200 rpm.
im going to look up the max rpm of the oil pump as i did not think of that.
i dont want to be accused of not using search function
btw motor was balanced also

But on the forums it's common. Do a search and you'll find 1,000 post talking about upgrading oil pump gears, and how the stock gears are a known weak link. Cheap insurance, etc. Maybe find 3 people that actually broke them. Maybe. Anyways look into it and draw your own conclusions.
I also ran the stock throttle body and never had a throttle body screw failure. That probably was luck, because that failure is wayyyyy more common than broken oil pump gears. (you can probably find 20x more evidence of failed throttle body screws vs oil pump gears, for example) There's people racing miatas that are naturally aspirated that have had that failure. That one actually does happen, so if you rev to the moon consider a different throttle body.

Oil pump and damper are normally considered "necessary" for "to the moon" rev limits. Pat may have gotten away with it. But people have also gotten away with running 300+ on a stock motor. Or 300 through a 5 speed. But I blew my 5 speed at 220hp, and others vented their blocks much earlier.

Rebello said that 8k would be no issue with with springs that I had. mention of the oil pump was never made. apparently they have never seen a broken one and have been building miatas for quite some time spec miata, turbos and such. Brian who works there "owners son" who is after all the time i have talked with and knew before this build is kind of a friend now , had a 375 hp 1.6 and used the stock pump..
If the oil pump breaks at RPMs he sets me up for i know he would feel bad esp since i have known him for a fair amount of time and live about 15 miles away from their shop.
apparently most people who are breaking them don't have a fully built and balanced motor. i could be wrong here too but that makes a huge difference in hard metal life.
I honestly i really appreciate all the time you have spent with me already.

Those valve springs should be fine then. 7,000 wasn't sarcasm, lots of folks think the stock oil pump gears will break above the stock 6,900 RPM redline. I've rev'd BP's to 8,000, 8,500, 8,800, and never failed as stock oil pump. That's my experience. Apparently I'm really "lucky".

If anyone wants to make a point for using a better oil pump, post oil pump pressure data on your motor before/after the pump, or post pics of your broken oil pump and what conditions you were operating at when it failed. This forum is pretty good about no BS, data/fact/actual experience, but for some reason that doesn't apply to oil pumps? That's what's sad about oil pump gear failures, there is almost No evidence of it, so people make analogies (this broke at... that broke at...) excuses (cheap insurance, while you're in there, why not).

Several years ago I spent a few hours looking for ANYONE that actually broke an oil pump gear. I found 3 who had pictures of the failure, and two of them were not using a harmonic damper at all (were instead using an aluminum pulley that replaced the stock harmonic damper as it saved weight) and one was using a damper, but had previously run the mentioned aluminum pulley that replaced his damper but switched back before his oil pump failed. If oil pump failures are common, I'm sure a quick search will turn up several people who have had such failures.

That says nothing for why oil pump gears fail, or that yours failed under what conditions, or what improvement you have measured with a different oil pump. This forum is supposed to be no BS, actual data, actual experience, not hearsay.
