Does ST205 OEM camshaft fit into ST185

[davidleonardi]

Hi...

i would like to know does the ST205 OEM camshaft can be fitted directly into the ST185 engine or not ??

If it does, does it make a difference in performance or not ?? i only want to go for mild mods. kindly advice, realy appreciated. Thanks.

if you want mild mods, cams are not the place to start..

If you are going to the trouble of putting ST205 cams in, you'd be better off getting the rest of the setup and installing that, the ST205 shim under bucket setup is a popular upgrade for people going for bigger power levels in their Gen 2 3SGTE's. Waste of time though if you haven't done the basic mods first.

If you are after mild mods, you should start with things like exhaust, intake, and boost increase.

Yes it can.

and yes it should provide a mild increase in performance.

I have done all those basic mods that you mentioned. Such as:
> 1.5 stainless steel head gasket
> ARP Bolts
> 3inch straight exhaust system
> w58 gearbox
> haltech e6x
>New gasket kit
> Oil Cooler
> Oil Breather
> and still many other mods

What I would like to know is that does the st205 oem camshaft will fit directly into the ST185 Engine or not ? thanks

As Roundy said, yes it will.

[davidleonardi]

As Roundy said, yes it will.

Sorry but 1 last question. If I would like to buy this camshaft, do you think I should buy or used part ??
Is there any of this oem camshaft come with ceramic coated originally ? Kindly reply. Thanks.

wouldnt be worth the money to buy it new from toyota if that is waht you were asking.

only the st205 intake cam is worth installing. the exhuast cam is no better than the st185 one.

they do not come ceramic coated nor should they be

The 205 camshafts have another 0.5mm lift, so should be a little improvement on the exhaust.

only th intake cam has the extra lift. the exhuast cam is the same as the gen2(8.smm lift) but with better timing. same can be achieved by retarding the exhaust cam 6deg's.

or get a gen2 NA exhuast cam. same timing as gen3 turbo with .3mm extra lift.

best still in oem specs is get the gen3 NA inlet cam for 9.8mm lift and approx 250duration.

David: Looks like you got a nice RWD set up. What car is it in?. Also if you don't mind, can you please post up some picks, would love to have a ganda.

Quick question why don't you upgrade your turbo? instead of CAM?

I want to repeat what you meant . Are you saying that if I want to change the camshaft, I should change to the following part:

Inlet cam : Gen3 N/A 9.8mm and appox 250 duration lift ( Ex ST205 )
Exhaust cam: Gen2 N/A extra 3mm lift ( Ex ST165 )

If it is, Sorry but I still do not get it. Aren't these parts come out from an N/A engine ? Why are they better than my stock camshaft ?? please explain again cos I'm new to automobile. Thanks a lot. Really appreciate it.
