Hey Guys.

Im sure there are plenty of threds out there in regards to the Bisimoto camshaft. Especially in regards to their build quality etc.

I currently have a built & sleeved D16, with a Gt3040 pushing 25psi of boost, PnP head etc. I believe my current camshaft is suffocating the engine and looking to let it breath more and make more power at higher RPM. chaseing 350 - 400 whp.

Firstly in regards to Build quality of these Bisi units. These days have they generally improved? people out there with these camshafts are they happy or not? how are both these units at idle?

To upgrade to the Bisi 2.4 or 3.6 i would deffinately purchase their suited valve train, however wanted to know is there anything special installation requirements with these units? Are they simply drop in the cam and valve train and away you go tuning? or will the head need to come off and have any sort of specialist machine work with the valves etc?

cheers guys

I've personally never had any experience with Bisi's cams - but after reading and seeing the tons of problems (especially with overseas shipping) I would be hesitant.

A ton of people praise Delta's work - they could help you out with a custom grind and provide you with the cam card (unlike Bisi?).

I would check out some of the members' builds with higher power like yours to see what's popular.

No. The cores that are being used for "billet" cams are poor. This has not nor will be corrected. There are many reports of camshafts wearing or causing atrocious wear on the rockers.

Idle is completely tune dependent. They will idle fine if you have a good tune.

They drop in, as long as you have appropriate springs. The 3.6 might need some clearancing, but you can do that with a dremel as long as you are going to clean up the shavings well.

Stock cams do up to 400WHP. I am not sure that your cam is your issue.

+1 for Delta if you want to save a few and still produce numbers. The 272-2 is a clone of the 2.4 even though bisi will deny this. The others mentioned work good if maybe a bit more coin. Did I already say FUCK BISI??

Bisi doesn't deny that there are clones. He denies, correctly, that a regrind will perform the same as a billet cam. He is COMPLETELY correct about that. I really wish people would be able to sort through all the BS.

I was looking to go bisi 2.4 but after a lot of research, I decided to go with a delta 272-2 cam. A lot cheaper, will outlast your car, and will perform great.

Billet cams are not recommended on the d because they tend to be of poor material quality. A good regrind from delta or colt will be your best option because the oem cores were practically indestructible and Honda had amazing qc on the d series cam. Plus bisi ships his regrinds out to Webb anyways. But charges a huge premium. Delta and colt both do their grinds in house and have some of the best customer service in the industry.

The design of bisi's cam is good just the materials are sub par. If it works great. Just dont expect any customer service if it breaks.:3dbiggrin:

so who are the manufactures that have the same cam designs as the bisi 2.4? what are their web pages / contacts? and what are the unit numbers?

Someone mentioned that the bisi 2.4 = delta 272-2 cam (same unit but better quality material / workmanship)
