Thread: Need some SR20VE w/ N1's and Nitrous advice build??

OK here's the deal now I really want to get the most out of my VE powered car and my next best option and most reasonable and reliable option is to finally get some N1's along with s/r's, cam gears, and really see and hear what this engine is capable of doing especially when she is getting a decent shot of nitrous down its throat at around 8500rpm, but I will be adding a VET HG or whatever is strongest and a set of ARP HS's that I pulled from one of my previous builds. Should sound pretty damn amazing and hold it well with the proper engine management.

I am currently using the sr16's, which really made a nice increase in power, but it just isn't enough to keep up with the turbo guys. I need to make in the 200+whp range to put myself back in the low 13's with the added power of the N1's, cam gears, and additional rpms.....Even more once I get the nitrous, which I am dead set on doing instead trying to boost it



Basically I want to make around 210whp or really close all motor and with do it with my set-up below + some added goodies like first getting my calum ecu returned(no problem with that yet), add N1 cams, some b/c springs and titanium retainers, raise my rev limiter to 9K, which sounds good to me and the cams and head should do it w/o any issues I am assuming?? Do I need some rocker arm stoppers? Even though (btw I will be adding some ARP headstuds for later on(since I already have them) and I am also adding a stronger HG(again which is the best? or should I just buy a VET?? , but after that my question is HOW is it possible to rev with a calum basic ecu????I thought all they can go to is 8010, so I do need a new aftermarket igniton and coil don't I? Which system is recommended and used by most of the 9K+ revers and what model numbers do I look for? Now if there is anyway to do this through a calums' ecu or is there some way around cam gears set at??? This is where I need some peoples VE first hand experience, knownledge and input, because I have no idea where to set my cams gears at, so somebody chime in who knows what they are talking about and has or is very fimilar with the same set-up I have especially the same ssac header w/2.5" downpipe, going straight to a 3" test-pipe, and finally out a 3" mandrel bent exhaust all the way out a freeflowing magnaflow mtuffler! There is NO back pressure in that exhaust.....

My aim here is to make the most hp that I can make out of the VE motor as is everybody's i guess??, whether it be with the N1's with the s/r's, cam gears set at +5 -5 or +2 -5(new one I am hearing with ssac header)and the 9K rev limit or should I just stick with my sr16's maybe grab geras and s/r's for them??

I know this stuff has been answered, but the answers are all over and really hard to put together for he true answer!

thanks!

just spray it.. you over complicate everything, all of what you posted has been done already

I would go with a different header if you are looking at over 200whp.

quick answer....you'll definitely need rocker arm stoppers with the n1 cam profile if you're going to 9k rpms!

I just have one question... why use any springs/retainers at all with N1 cams? They won't even start to float the 20ve springs until over 9K. I guess people run up to (or over) 9500rpm without many issues. I think 9K should be relatively safe. 8500 should hold up just fine.

I feel like i'm on the same page as you dude. I am running the N1 cams now and the car is quick but not where I want it. I am planning a mild bottom end build so I will be spraying this bish and see how she likes it. I think a nice 50 wet shot would be sufficient. Hoping to get it together within 2 weeks. The SSAC has been making some crazy power. Don't ask me how but ****, they have been. 200+whp tuned with a ssac 2.5''. I want to get some new domes for the bottom end when I finish this semester of college. I think some high compression would be a nice thing!

As far as the revving, a good friend of mine has been revving the hell out of his N1 cammed motor. I rode in it and saw the tach shoot past 9K while tearing apart the tires. I have also had my car shoot to 9K when I had a "friendly encounter" with a built civic.

Rocker Arm Stoppers ftw!

Jonwepa, you need to walk before you run.

I would say that you would need double rocker arm stoppers, since there are two cam profiles, they should have two different sets of stoppers.
I personally would run stock sr20ve springs and retainers and rev to 9k all day. Still have yet to see a ve fail from revving to 9k, and this is a daily thing. The stock sr20ve springs are stiffer than the n1's. spend the money on a better header and tune the car. Then when the intake is the bottleneck in the system, then you will need to either have one made or do it yourself. You want to get some quicker times with your car, run n1 cams with stock springs and retainers sell the sr16ve cams and with that money you can get some sr16 pistons. Modify the pistons accordingly to what kind of fuel you plan to run and make sure there is enough valve clearance for your setup. Run a 75 or 100 wet shot. That should get you close to where you need to be if it is tuned correctly for alot less money. Once you reach the limit of the ssac look for a asp budget, a gen 6 or an old aebs. Obvioulsy there are beter 4to1 options, but then the cost will rise. The ssac header is a great bang for the buck header, but it will become a restriction around 200 whp give or take.
