bp turbo

[rogerstrampoline]

Hey guys doing the bp turbo still.....am getting the bpt cams, will they work in the na head when i put the rest of the bpt setup on? Just cuz I don't want ping at high revs

[TheMAN]

of course they well... tonnes of guys in the UK did that because the NA head flows better!
if you haven't found a source for the cams, ask clean cookie... he has a set he doesn't need

[rogerstrampoline]

Already picking up a set next weekend thanks for the quick reply man, much appreciated

Yep, as above mate. Replace your lifters while you're in there.

Ive got a set of cams and cam gears to suit what you want to do, they wont go in my engine as ive got the later style SUB rather than HLA. let me know if youre interested.

[rogerstrampoline]

Derb I should just come straight to you for stuff hahaha

[rogerstrampoline]

Cheers cookie ill let you know how I go

Thanks, but always post it up mate. I'm sure I'll never be close to being 100% right on everything, plus if someone else down the track has the same problem, hopefully they search and find this thread instead of posting another one.

Would I also need to change the cam gears to bpt and get a new timing belt? Or will mine be alright? Cuz I only got a new timing belt 10,000km ago

[project.r.racing]

belt and gears are the same.

[Clean_Cookie]

I was told differently (that the gears are different) but Ryan's probably right!

[Cosmo Dude]

Gears may be a different part number but they are interchangeable. Cams must run at half crank speed.
CC if you want a set of Mx-5 B spec cams we could come to an arrangement.

[rogerstrampoline]

Thanks guys I'm good with the standard bpt cams for now....only gonna run like 8-10 psi due to pistons if i want more power ill just get another car hahaha

no they're not... the cam gears are exactly the same between the non-turbo BP and turbo BP, therefore same part number

the mazdaspeed cams would not be advisable... they have high overlap which hurts turbo performance (some overlap is good for turbo engines, but too much is bad)... they are strictly for non-turbo setups

[rogerstrampoline]

hahaha figured when i saw MX5 lol unless they would be the turbo version, cuz i know mine have overlap with the NA etc which will hurt me at high revs, which is why im going the bpt cams cuz i know they have different degrees etc to allow for boost

[Clean_Cookie]

you want more overlap for turbo.

[rogerstrampoline]

i thought too much overlap was bad when boosting alot.......

[TheMAN]

google is your friend

It depends on your particular setup but you're much safer going with less overlap. Otherwise you have a high risk of burning exhaust values & overheating the manifold.

If you're running low boost & a small hotside you can get away with higher overlap.

[rogerstrampoline]

Due to the high compression pistons I was only going to run around 10psi just to be safe I'm looking for a fun car not a race car hahahaha but was going to go less overlap just to be on the safe side, I'd give up power for a more reliable car
