Ok so i finally have a beater to drive so im thinking i migh lift the engine out of my 99 2.2 up enough to put a cam and new lifters in....first off anyone know of any good and fairly aggressive cam for the 2.2? or would i be better off just doing the crane 1.6 rockers? Or should i do a cam and a set of 1.5 fully rollered rockers? figured it would be afun weekend project so any help would be great..thanks alot..phil
JBodyperformance as a cam for the 2.2
i think they do anyway
Im a Xbox 360 fanboy...and damn proud of it!!
Yes they do..im kinda looking for one that has been used by someone and gotten decent gains out of it ..well for the 2.2 anyways..are they the only ones? well other then custom??..phil
i don't think many people do just a cam on the 2200, its usualy done with a rebuild of an engine because its a little diffcult to do while the motor is in the car. so not alot of people are going to be able to tell you the gain just from a cam on a 2200
it would also probably be cheaper to send a blank cam into comp or crane cams and have them do a grind for you.
By blank you meana stock cam or areal cam blank? Also just looking for values if its a custom grin cause to be honest i dotn know much about that stuff..and im just going to pull th engine up enough to take the cam out....car has very little miles..but the lifters are a bit noisey and the cam is new so it might as well all be new..phil
Although this answer cam from the lifter thread, it deals with your question and your future plans.
Read this! (Yesterday, March 30,2006, answer to ln2johnny.)
Also remember that the 2200's stock valve train can only handle .480" lift without interference problems. Read through
this thread, yes it's long, but you'll see some of the problems we've delt with and eventually how we solved them.
Jack, would those two Crane regrinds you recommended be 'computer friendly'? I'm not sure what kind of duration would be considered 'wild' on our motors...
fortune cookie say:
better a delay than a disaster.
I spent some time thinking about cams this morning. The LT4 HOT cam design used by GM has been used on both the gen3 and LS series engines. There's even a similar grind for the gen 5 big block. The original smallblock version is .525" lift with a 1.6 rocker (.492" w/ 1.5 rocker) and duration @.050 is 218i 228e, 112LSA and 110 deg intake centerline. The cam has a lope, but has very little overlap. It's mild enough to run with speed density ecm's but powerful enough to make over 400hp on a 350 with mild heads. It's a super popular cam. I've been wondering about using a grind like this in the OHV with reduced lift. In stock form, the cam produces power up to about 6300 rpm, which is just the right range for a street type reasonable cost engine. It would take some head work to allow the cam to work its magic in the OHV, but adding a turbo can certainly overpower a weak port at higher rpm.
Anyway, the computer dyno thinks it's a good idea.

hmm well i was just thinking of going with the jbp stage 2 cam....anyone have it likes and dislikes??? phil
OHV notec, yes, those grinds are computer friendly.
Slowolej, the problem with using a SBC grind in our motors is that the actual power band is about 400-500 rpm higher on our motors. This is because of the smaller cylinder displacement doesn't take as much duration to fill with air. The smaller intake ports and valve sizes doen't make enough of a difference as far as volume is concerned.
According to the info I've collected from Crane Cams and other cam manufacterers is the best you can do rpm wise is about 214-216 deg @ .050". This is putting the top of the power band for the cam at 6000 rpm, with no room for error. Usually you would want peak power at about 200-400 rpm before red line, to allow time for shifting and keeping you within the powerband.
The LT1 Hot Cam would be a good grind for a 2.2L with the HPT and aftermarket spring set-up though. I was thinking of a cam in that range, if I can work the HPT and a laptop into my budget.
Philly D, you could get a cam core and have Crane regrind a cam in that power range for about half the price. The Crane HR-208/292 is what I have, with the Crane 1.6 rockers and is nearly identical. This grind was tested by Crane and Howell Automotive as a grind that they were contemplating selling. Howell decided against selling them, due to the lack of demand. The JBP grind would actually have slightly less low end torque and throttle respose, than the Crane grind, but would respond better to a supercharger or nitrous. The JBP grind would have a little more reversion on an N/A car with a full exhaust, but would work better than the Crane with the stock exhaust.
