ok i want to upgrade to a 37R,i already have a buyer with cash for my 35R.now if i upgrade to 37R,finish fuel system,go with buschur race FMIC,buschur intake mani ported,and alky should i be good?will i see good numbers?oh should 37R be used only on built motors?

i have AEM,pump,1000cc injectors,cams etc..


so should i go 37R and finish what i was gonna do or keep 35R and finish what i was gonna do?( fuel,race core,alky etc?)

AMS said 37R is only good really for race gas,but if i do alky and like 27psi shuld i be ok?thanks,let me know...if i do upgrade it will be very soon..thanks

 

A 37r is unreal at high RPM's and High Boost. @ 27psi your still a bit shy of it's sweet spot but it should run its *** off.

i have a Complete RNR 37r Kit for sale in the Classifieds section with less than 1k miles on it. And no wait time.

 

I dont like the alky, that is a fail safe way of trying to make more power. if the alky kit stops working your engine could be toast.

 

^very true...but ive heard good things about them and never heard of one failing

i only need the turbo,not a kit..ill be ordering a 37R turbo from AMS soon if i hear good things about havent it with my setup

 

if you don't mind full boost at 5200 rpm then you won't have a problem.

 

i thought it was closer to 5700-5800

 

well can i run a 37R on stock block?

with aem 5bar uego/wideband/1000cc inj/fuel pump/ams fuel rail/ams fpr/buschur intake mani ported/buschur race core with piping/alky/fulll 3in exhaust/ngk bpr8es plugs/throttle body/272 cams

with that set up can i run 37R or just stick to 35R?

 

27psi on a 35r is no fun. Go 30's!

 

well on pump gas and everything else but a built motor/head,i doubt i can do 30+psi on pump..i dont think i can do over 30psi on race with out a built motor

 

keep in mind the stock block can only handle up to 500whp safely...anything above that is pushing it.

If you're upgrading to a 37r and want to get past 500 whp (if you dont then what the hell is the point), then you have to build your engine, and then you get into the question of 2.0, destroked 2.1, 2.3 stroker, etc....

 

You arent maxing out the 35r now with your stock block. No point to uprgade yet, the only thing that you will get is more lag. I wouldnt upgrade turbos until I maxed out the one I had...

 

true..well on a stock block and 35R with 27psi and the mods i listed AMS said i can crack 500awhp on pump...so maybe ill just stick with 35R

 

There is some many threads about people upgradeing to a big turbo without haveing the supporing mods then wonder why they dont get the power they really want to get.


Ill tell you right now your not going to get more then 550whp out that setup even if you do it wont be for long.


A say stick with the 35R why upgrade if your happy with what you got. And besides with a few more mods you can hit high 9 seconds all day at the track with a 35R

 

What cams and sprockets are you running? The bigger IC should be helpful in your case. Maybe with it you can run a bit closer to 30# on pump. Are you datalogging and there is no evidence of engine knock at 27# on pump?

 

I love the 37R!
