Would this be a good alternative to the 1.8L Cam. My biggest criterion is avoiding modification of the Stock ECU at this stage.

Any opinions?

Getting a new cam and not getting your car tuned for it is retarded... I can see $100 for 1.8L cam, but that's a lot of money to just throw on wind man... if you plan on doing something, do it right!

My car is a hyundai coupe 1997.
I just had the performance stage 2 cams installed from www.rpw.com.au, supplier in australia.

Parts you definitely need, as the mechanic needed to adjust these for my car;
adjustable cam gear for the timing (mine was from ebay brand OBX).

Tuning and Ignition needed to be tuned, but I had an aftermarket computer (haltech e6k).
I'm not sure if the stock ecu can handle the changes.

Results from mine was 13hp extra power on 6500rpm
and a massive increase in acceleration and torgue from 2000rpm to 5000rpm.

 

Agreed. Too much of an increase over stock for the ECU to be able to adjust...

 

You will definitely need some ECU adjustment. Anything over 240° duration WILL need ECU tuning, of course the farther you go, the more critical the tuning will be.
With the 1.8 cam you don't really need tuning because it's on the ECU range of adjustability, and as OP said, it's only $100, but for more than $200 on cams, I'd definitely go with a tuning.

 

This is what 18aCobra said to me yesterday I think

"If you want a good cam setup for the street, 264's are the way to go. The ones I have (250 degrees) are too small, I should've went bigger. The 272's are only good for race vehicles as they don't idle very well. With 264's, you will need to tune the car somehow. You won't need a standalone, but you will need an SAFC or Emanage to add more fuel. The 250's won't require any tuning, but they cost as much as the 264's, so they're not really worth the money"


He is running 250 deg cams right now. Like I said, I'd rather not have to worry about tuning the engine at this stage. When I'm done with all mods incl a P&P head, then yes.

 

And those 250s will give you 3-6whp at most... is it worth it?

 

I would recommend 264s only as a finishing mod for the car... as they are expensive, and while the gains are good, there are better mods to be had for the money.

 

Of course cam shaft should not be your first mod, but after your car get enough air in and easily gets the air out, you should think about a cam.

 

So, can I get the 264's with just an safc for now? I do plan on getting an e6k, but can I run them for now with just an safc adjustment? I thought I would have to modify the ignition timing? Anyway, would it be ok to get these for a 20 psi turbo setup? If not could someone please give me a quick explanation of why? I mean, they do increase volumetric efficiency, but I suppose the extra overlap could hurt something?? Thanks guys.
