[buzz11]

so i did some research on cams but im still a little confused on how to upgrade. i plan on going bisi. so i have to remove my camshaft (or get another camshaft) and send it to bisimoto so they can work on it? also i have to upgrade the springs depending on which upgrade rite? correct me if im wrong, this is just what i learned doing some quick research

yup..Bisi asks for you camshaft as an exchange or regrind by giving them your specs...Bisi is the number 1 recommended around herei'myet to find some punk say otherwise Bisimoto hasn't messed up in simple shit so when you buy parts from them expect quality work...

yeah the springs is a must even when you have the A1 cam and wanna swap to the more aggressive A6 camshaft your going to need the springs as well... imagine springs being run in your F22a1 for about 18 yrs the putting a bigger camshaft for performance those springs are going to take a beating being compressed alot....bisi has some springs too....oh and if you can send them your camshafti believe you can buy a core off them for about 100 bucks....seems fair to me!

if you get the stage 1, i've heard you can get by with your other stock internals, and also be able to run with the stock tune. if you go with stage 2 or higher, you need to upgrade your springs and get tuned.

Its best to upgrade the springs, its not a must for stage one. but if your going to change the cams just redo the head port and polish, springs and get a stage 2 or 3 cam. do it once do it right. nothing worst than have to buy cams 2 different time for the same car.

Thank you for the kind words! You are correct, here at Bisimoto Engineering we have cores for the non-vtecs for $100 and for vtec models $150

We also do have spring and retainer kits for both the Vtec and non Vtec models.

Again, correct!

The Bisimoto Stage 1 is literally a drop in and run camshaft. There is no need to upgrade anything else! The level 1 generally will give you 10% performance increase over factory! Bear in mind that if you tune with this cam your gains can be more.

The Bisimoto Stage 2 is a bit more of an aggressive setup. With this cam we suggest and recommend our Pro Spring & TI Retainer kit! Bearing this in mind a tune isn't completely necessary but again to take advantage of the performance abilities and potential of this camshaft a tune will help out to really extract every last bit out of it!

Its best to upgrade the springs, its not a must for stage one. but if your going to change the cams just redo the head port and polish, springs and get a stage 2 or 3 cam. do it once do it right. nothing worst than have to buy cams 2 different time for the same car.

Exactly! Mind you though our Bisimoto Level 2 and 3 are drastically different! The level 2 is reprofiled as an aggressive street cam where as the level 3 is practically a full race cam. Generally the level 2 is a good starting base for people before they get more aggressive. Also bear in mind that the level 3 also gets more aggressive with its requirements as it is reprofiled to be closer to a race cam.

In either event my suggestion is to get springs and retainers at the time of your cam purchase. Even if you stick with a level 1 it is nice to know that you have the security of 14000rpm before you can start to worry!

for level 3+

[bcjammerx]

shnikies, I doubt I will ever need 'em.

I think they are recommended for those who rev up to or over 7k on a regular basis...and required if you rev to or over 8k

Yup! For level 2 you only need the valvetrain, let me know if you need anything or if there is anything I can assist with!

Will the spacers even help in any way unless you're going with level 3 or X?

[randull]

Its debatable, to be honest in my opinion our Bisimoto Level 2 isnt aggressive enough to require it. Our Bisimoto Level 3 and X cams are race cams so with that in mind those would need the spacers due to the aggressive nature of the cams.

Weekend warrior setups generally are fine but anything that will constantly and repetitively see track time will need the spacers as well as extended rockers! Bearing this in mind, we recommend our valve train in both situations due to our assurance and testing. Our springs and retainers are spun test to 14,000 rpm to ensure that they will not fail on you our client!

Should you guys have any questions, comments, or concerns feel free to shoot me an email!

So the spacers are just more durable and don't actually provide any power upgrade, I would assume.

What is the difference between the stock rockers and the extended rockers? I know the race rockers are lighter, I'm assuming extended has a better rocker ratio? They must be somehow stronger too?

Bingo, dead on the money my friend!

[Sarthos]

Awesome. Too bad I don't have a spare 1600 bucks for the extended rockers. It's almost like a knife-edging and polishing process on the rockers for the shaved weight and then adding material to extend them, and I suppose coating for the strength?

Good information here! Makes me feel more comfortable thinking about doing a future Cam upgrade! =)
