Thanks man I really apreciate it.


Im going to buy the n1 cams and intake manifold soon( 1 month more aprox) if someone can get me the 20v cams for a good price I can do a lot of cam testing between the sr16 n1 20v and stock sr20ve cams...you name it..

Regarding to my setup... Im just waiting to te head gasket almost everything its ready for the build motor.
I was pretty impress with the sr16 cams.... this cams as I stated before net me 50whp over the stock sr20ve cams the spool its almost indentical Im very happy with the outcome 500whp under 16lbs its nice...and its feels very strong on the street (I will put a vid tomorow) My goal its to make 550 whp at 16lbs hope with the concurrent parts this can be done or at least get near this. I still have a lot of parts to change turbo comp wheel now its a 62mm can put a 66mm turbine housing to 1.32 ,with the built motor 9000 rpm n1 cams and intake manifold etc full boost must be under 5300 rpm in 4gear This proyect its going to be finished before this year ends . let you know the results as a usual.
critics and info regarding will be very apreciated.
Thanks.

That is right ..
n1 are first then the 20v I think the n1 will get he 1-1 between back pressure and boost that still pretty good well we will see.

wait so the turbine compressor wheel currently is a 62 and you might end up putting a 66mm on? Also you have a 1.32 rear housing you might end up putting on? I am going to go out on a limb here and say do you really need a 66mm comp wheel? You are barely in your current comp wheels efficiency at 16lb's. I also think your current rear housing will be about perfect with n1's however it is good to have the bigger one there if needed.

In saying alll this i would still like to see the results with the switching of parts. look forward to your 20v results, they should make as much a, if not more than the 16ve's without needing to switch the low cam so eaqrly and dip in power from 3200 till about 4700/4800

I would love to see a 20v 228 10.7mm low intake cam matched with a 11.3 244 vet low ex cam on the dyno with a set of cam gears tuned for low end power, just to see how good you can get spool and just compare the differences in low end and spool to the pair of 20v's.

Whats funny is I told a lot of people that sr16 cams on larger ( GT3076R and up) turbo setups makes a lot more power.... and that was over 3 years ago...

the SR16 cams to get the best spool you need to kick in the cams early, atleast the exhaust cam, at like 4000rpm or earlier. I do agree that the larger big lobes will help out though from the 20v cams.

100% agreed

This will be a nice comparo I also think the 20v will still keep the powerban little longer ...

Send me the cams and I will do it...

Cheers man.

can not promise anything, but might be able to get my hands on some vet cams. If i can get at a acceptable price ill buy them and send them on down. I always wanted to do this testing anyway so i wouldn't mind sending some down

If you get a good price let me know , we can divide the buy...

Dayum. Ya I have wanted to try out the VET cams on a bigger setup. They have much better engine response than my old 20ve cams did. I will have some results on my particular setup soon, but I honestly dont think the VET cams are going to react to the bigger turbos as well as smaller ones. The lower duration and overlap just won't have the scavengine effects that the 16VE cams have.

I would love to see how the 20V cams do though, because I have always looked at that particular cam setup as a perfect turbo cam for my turbo size.

^^^ i am only really interested in the low ex lobe mated with the 20v intake. The vet high lobes will be garbage on jp's set up.

i know of someone running 20v cams with your turbo and a .64 t3 housing. He gets full boost very very early. His way of describing the power delivery was like a worked v10. This guy is no stranger to crazy setup either
