HKS 272? cams into ST205 3SGTE

[camry-GT4]

Hi all,
Im looking at getting some HKS 272? cams on my engine. Has anyone done this to their ST205. Just want to know what difference it would make in power and RMP/boost kick in. Will the car still be a good daily driver?
Cheers.

The 272's are a bit wild for most peoples tastes as a daily driver.

With decent management you should be able to get it to idel OK at 1050rpm or so with ~10-12 inchs of vacuum. They are really only suited to a serious build with other significant volumetric efficiency enhancements and a big turbo. I'd say get the 264's for anything short of a full-on setup. Actually there are MR2's in the states making 600+rwhp on hte 264's.

Personally I run a set of 268 degree Wade cams with 10mm of lift, most people would not consider it to be a good daily driver but I love it. It idles lumpy at 950rpm with 11 inchs of vacuum. It's a pig to idle around at less than 2500rpm though until you're up in third or higher. My setup also makes full boost at ~5500rpm though.

Thanks Joshstix,
In that case I think I may be ordering the 268 degree HKS cams instead. I have never heard of Wade cams. Are they any good? Well priced? You totally lost me with the whole inches of vacuum thing. Also, I have heard some people mix and match the two different degree cams (different inlet, differnt exhaust). Is this work looking at or is it better to stick to a matching set? Also, do you by chance know what degree the standard ST205 cams are?
Thanks Heaps!

Camry,
Wade are a crowd here in Melb who build custom cams. Also try Clive Cams. Do you have adjustable cam gears on your 3s at the moment? Perhaps try these first as fine tuning of the stock cams can give a good increase in power (probably around 5 kw). A quick google suggests durations of around 235 and lift approx 8.5 but I'm not sure if that is for Gen2 or Gen3. I'm pretty sure that Gen3 had more intake duration than the Gen2.
What about putting 10mm of lift on your stock cams and a bit more boost?

[Joshstix]

I'm happy with my Wade's they were much cheaper than HKS stuff at the time and I could pick exactly what lobe design I wanted. They're also ground from new billets rather than being regrinds which is nice.

The numbers above are for Gen2 the Gen3 intake cams are 4 degrees and 0.5mm lift bigger than Gen 2 and hte exhausts are the same as the Gen 2 except they're 6 degrees retarded.

Hi there,
Might not be much help according to what you looking for but I did put 272 cam into my AE82 running 4AGE. I bought the cams from overseas. The car goes hard and feel great .. until it snap the valve springs ...

[oldcorollas]

different kettle of fish with the turbo dude... and your springs were dodgy

didn't you get deported? heh heh (just kidding )

ive got the hks 264s (inlet and ex) and valve springs, i wouldnt go any bigger then these for the street, as it is it doesnt idle under say 700 (usual idle is around 800) absolutely no power and a bit rough under 2k. after 2k all becomes smooth, then at 4200 you get a definite power kick when the "cames come on", after that its all pull. Get the 264

[Dimitri]

seems really strange, its alot different in a 4ag. i can understand that theyre 2 different engines and ones turbo one isnt.. but the idle.?

ive had hks 264s before and it didnt effect idle at all, in fact i would say it just woke the engine up a bit.

and based on that, my opinion is i wouldnt bother going any smaller than 272/264 on any engine if i were spending the money.

whats the lift on gen 2/3? Only .5mm bigger intake on the 3? but from what? gen 3s are shim under? is it to do with the CR?

Hi af300e,
I don't have the adjustable pulleys at the moment but will be ordering them (HKS) with the cams. Not sure what you mean about 10mm of lift on my stock cams means as Im still new to this whole camshaft thing. What exactly needs to be done to execute this modification?

Hi Cuts,
thanks for the info. I never thought about the valve springs. Is it a must to replace them when you upgrade the cams? What kind of purchase cost would I be looking at? As for the no power under 2K, I thought cams helped give low end torque power??? Did your low end power increase at all once you put your 264s in? The more I look into this, the more Im leaning towards the 264s instead of the 272s.

I wouldn't have any idea about what to ask for from Wade regarding mm of lift when ordering. Do you think there would be a big difference between a 264 profile compared to your 268 profile?

Lets take this back a few steps. It appears your understanding of things is a little on the thin side so I'd like to make sure we're giving reasonable advice.

What do you want to achieve by upgrading the cams?
What is your current engine setup?
What future modifications are planned?
How much power do you want to make in the end?

Yeah, Im still a newbie when it comes to the technical side of things. I guess what I want to acheive overall is around 230 - 250 kw at the wheels. Current engin set up is stock ST205. It's actually not in the car yet, sitting on an engine stand in my garage. I have purchased an equal length mandrel bent manifold & 3inch dump pipe so far. I am about to order the HKS cam pulleys also. I just thought it might be a good idea to order the cams at the same time and put them in all in one hit. It looks like I may need to order valve springs too. Not sure what th hell they do?
Once the engine is in the car and running, the next stage will be looking at engine management, probably a Haltec system, bigger injectors and a turbo upgrade. Does this sound like a good game plan or am I way off?

[Roundy]

will a stock computer run the cams? i know a gen 2 can somewhat manage it due to using an airflow meter, but the MAP sensored gen 3 might struggle a bit.
