OK so I was first thinking of just a budget engine rebuild but want to know how much power is gained from the Engnbldr street RV head and 268 cam? I will probly add a Downey header and exhaust. Is it noticable? My 4Runner is a daily driver with exhaust and 31's. Just want help with the hills, and maybe it can help mileage by me not always standing on it. The original motor died at 277,000 miles. Broke timing chain while on freeway.

 

its better than stock some dyno #'s i found off google



Comparison of 22re motors with different modifications
Solid line:

Stock camshaft
2.75 inch exhaust
Aluminum 2.75 inch intake
Broken line:

RV "C" 261 degree camshaft
3.0 inch exhaust
Aluminum 2.75 inch intake


from here http://www.22reintake.com/rvvs.stockcam

 

by that graph, the only change is the torque shifting 500rpm lower. Doesn't really seem worth the money at all.

edit: power also begins dropping off about 500rpm sooner.

 

that exhaust seems quite large for just a 22re. i have the engnbldr 261 cam and lce header with 2.25 full exhaust, the difference isnt huge but i am a little faster than my buddy that has a stock 88 pickup on either 30s or 31s i dont remember which exactly.

 

yea he is running to big of exhaust on there, i have the head in mine and its faster than stock

 

I suggest you take a look at the LC Engineering header and exhaust system. I think it's the best on the market, FWIW.

 

yea i run LCE header/flowmaster downey intake with the 261c and street rv head it pulls harder than stock
