will the stock sr20ve rods hold more than 8000revs?

are the forged ones must have for the 8+ sr20ve?

Can I just use arp rod bolts or stock rnn14 sr20det rods?

stock de rods will work too. you also will need the 8cw crank.

Yes they can hold more than 8k.

My friend VE with stock valvetrain sees 8300rpm daily.

run your 4 cw crank, its lighter, its well balanced from the factory.

run oem de rods or ve' rod's.

my buddy runs a ve with a s&r kit in the valve train, along with n1 cams and the oem bottom. it see's 9500rpm everytime he takes it out.

Haha thats crazy that what IVAN's car use to take it up too with the Frank Stage 4 cams. It felt like it wanted to keep going past that too lol.

mine has seen 8k for 2 1/2 years

I want to build a reliable engine. I've already bought nismo thermostat, bc s/r set, acl bearings set. don't want my engine to lose power.
need some rings and gaskets and I'm ready to begin.

thanks.

This is an interesting topic.

I am wondering if you should be more concerned about the valve springs?

I was told that revving higher than 8000 would float the valve spring in the sr20ve so i cut my rev limit to 7800 (using the sr16ecu that revs to 8300).

I am wondering if that is a myth but then again I am using sr16 cams. I know I'm a bit off-topic but can you guys shed some light here.

are the 16ve springs and 20ve ones the same?

should not be the same,sr16 can rev higher

Oh yes they are!
13203-1N500 SR16/20VE Outer Spring
13204-1N500 SR16/20VE Inner Spring
Used on N15,B14,B15,U14,Y11,P11

13203-1N520 SR16VE.N1 Outer Spring
13204-1N520 SR16VE.N1 Inner Spring

Oh yes they are!
13203-1N500 SR16/20VE Outer Spring
13204-1N500 SR16/20VE Inner Spring

13203-1N520 SR16VE.N1 Outer Spring
13204-1N520 SR16VE.N1 Inner Spring


So if the springs are the same, why some people say that revving the sr20ve past 8000rpm (especially with sr16 cams) will damage springs?

I really need need to see the logic cause I am revving to 7800rpm whereby I have the capacity to rev to 8300rpm!

Is it because the internals (crank, rods) of the sr20ve are heavier/bigger and can cause more damage vs that of the sr16ve?

I was mistaken too. thought they differ.
but now I'm using bc s/r set.

I plan to use nos on stock sr20ve bottom. how much it can hold?

yeah i thought they where the same too, and now i see that definatly are, but i was puzzled to why the safe reconmended rev limit on standard springs is 8k but 16ve goes to 8.3k standard.

however many people rev to 9k on a 20ve no problems. i suppose the shorter stroke does mean capacity to rev higher, but this has no relation to the top end

It's the cams. The bigger the cam the higher you can take the stock springs. SR20VE cam is smaller than the SR16VE and N1 is bigger than both of them. If you take your Sr20ve cams to 8k u run a good chance of floating the valves. SR16VE to 8300 maybe but I would never test it unless I wanted to pull the head off the car. Sometimes you will bend a valve slightly and not even notice it because the motor will sound fine. That is until you take the head off and have the valves checked. If you want to rev to 9k get some springs unless you have money for the down time needed to fix the problems that will come from floating a valve.

I don't see a point of revving an engine more then 300-400 rmps over the cams peak power.

how much hp will the stock sr20ve (with sr16 cams) will hold. I plan to use nitrous. Will the stock bottom hold 30 hp, or I may use 50 hp?

Depends on the engine and how much there is at what rev - if 300 over peak is where lower gear power matches next gear at shift, then that's where to shift. That takes some dyno work. Else, you don't have a clue, and without hard data, shifting above redline (7500) is simply asking for nights in the shop earlier. Somebody above said they'd done 8300 for over two years; I'd say that's pretty decent data assuming he's engine savvy. Miko said to set the digital 6 at 7500 with stock internals. If somebody has HARD dyno data otherwise, or HARD data consistent 1/4 times, or HARD data on lap times doing otherwise, I'd be happy to listen. Else, just shoveling waste material upwind.

Are you talking about the valve springs or the bottom end of the motor going over 7500? 9k and 9500 I have seen myself on the road and on the dyno.

Run 30 is to 9500 on the Franklin Stage 4 cams. Drove it on the street and took it to 9k as best as I could tell with the factory tach. The bad part about not having a rev limiter and big cams is it feels like it wants to keep going lol. 8k-8500 should be fine. The SR20 still dosn't like reving that high for long because the water pump just can't keep up with it for a long time still.
