Thanks nizanR much appreciated budi.
Hey guy's did a little research and they saying rocker stopers is bad as it prevents the cheap things from braking and causes bigger things to brake how true is this? And my valve bent when my rocker jumped off is there no other way to prevent this from happening?
RAS does good only... as far as i know... if you want to rev your engine it a must!
Rocker Arm stoppers is a good idea. Especially as you running uprated cams. Perhaps you should look at improving your vavle springs as you are running a bigger cam than stock.
What is your rev limit set at?
7000rpm or 7500rpm not to sure now but last time i took note is 7000rpm, thinking of getting a good set of valve springs and valve retainers
solid lifters !
problem solved , or as 100000 rpm rev kit
Hey whitefang could you give a quik run down and a discription on that solid liftes as im not too clued up about that?
LOL ................... dis kak duur conversion , mar moer sterk ,
Dont bother with solid lifters. Upgraded springs and retainers is the answer.
Well the problem with just going with stiffer springs etc is that it puts even more stress on the lifters. I would go solid lifter but you looking at about a R5000 conversion. Springs and retainers are cheaper and I would do those also. problem is the amount this all ads up to. However it is worth it for a bullet proof head setup. Note though that you will still need rocker stoppers.
Hey Phoenix s14 that mod sounds like the head will be bullet proof but very very pricey just the valve springs and retainers alone R2899, wish i had the cash.
The problem with going solid lifters, stronger springs and more aggressive cams is rockers are known to start breaking.
Kyle, what damage was done to your head? Have you taken it off the block? Any cracks and or detonation signs? I'm interested in it if it is good condition (apart from the bent valves) and you want to go straight cam. Or you could look at changing your full engine to straight cam and letting me buy the bare engine off you if that's the route you want to go. The block and head would need to have NO detonation signs on it though.
Hey djtreble im not selliny my engine budi, as for the damage the head is coming off next week then ill know for sure,i just want to prevent the rockers for jumping off but seems like a hard task doing it without putting stress on the other parts of the motor.
Fix the the bent valves, make sure whomever does the headwork does a proper job, SR20 heads needs to be measured again and again to ensure clearances is perfect.
Double check the cam gears that they havnt come loose. Ive had that problem.
Get rocker arm stopers before putting the head back on.
Keep the rev limit at 7000rpm.
Save up for upgraded springs.
Your block and head needs to have a mirror finish when putting on a cometic head gasket, otherwise it will leak.
Have you got the car remapped yet?
Nope not tuned yet since i got the car just been spending all my money on fixing it and petrol lol i need the heavens to bless me with parts at good prices.
Gimme a call and lets see if we can sort you out with some parts and fixing of the car.
