Default Questions about n/a vs boost power

I was chatting with a yota tech I know abd he asked " you do all thus little stuff why not change cams n be done." my response was...what's a cam? He almost flatlined. He's digging around for this jap website for direct order parts since they auto cross the 2.4 so much over there it's the first thing Trd suggests I guess. Anybody know of anyone else that makes new cams for us?

I edit this thread because I've gotten to a point where I either start doing major NA mods or go boost kits. Mind you i have an auto with 50k.

I'm either going to not mod for a long time and save up 5k for boost (gonna take for ever)

Or look for more N/a stuff to do.

So far, unichip,intake,header,2.5 exhaust, trd springs.

I plan on doing the NST pulley system but after that im not sure what else is left that I can do this car to get more power out of it. besides cams which apprently aren't really going to do much for our engines.

Anything else anyone can suggest that i might not know of? I do like the aspect of instant power with N/a rather than the lag of boost (though it sounds cooler.) I also know im not going to find the trd supercharger for the box ever.

Why did he say change the cams and be done? What are your purposes for the cams exactly?

Well not be done but since I'm trying to do everything but boost its the one big thing I never looked at. My purpose for getting them would be for more power to the wheels. He said instead of a maybe 1+ in a cai your looking at 20+ for cams, just don't do it yourself haha or without him or another tech to help.

Tl;dr power

hmm thats interesting. Seems low power boost for the price tho. But it would be fun. What other kind of benefits do you get from cams? I know a small amount about cams but always wanting to learn.

Brain, The stage 2 cams Bc0341t will give you 18 HP in the NA engine but they do require the BC0340 spring kit. The cam change really wakes the engine up as the OEM cams are very mild. Let us know the shipping address and we would be happy to do a quote. Thank you, Dustin Spencer ------- Brian Crower, Inc. 161 So Marshall Ave El Cajon CA 92020 P: 619-749-9018 - ext 101 F: 619-749-9128 www.runbc.com


Thats the email i got back. I dont know that much more about them. I know it helps with deeper range RPM wise, plus 18 hp to the Wheels is pretty spiffy for trying to go the non boost way.

Kind of a dumb question but I thought the stage 2 were for boosted engines and stage 3 are intended foe NA?

that spring kit is almost 300 by its self... so this may nor be viable for me

Search the gen 1 TC section before wasting your money on cams. Very poor bang for the buck on our engines.

I might know where you can buy a very slightly used Descendent turbo kit for a very good price, if that interests you.

Sorry guys, when I posted about the turbo kit it was listed for sale in the PPC section but now it's gone. I know the owner though and I'll PM him to see if it's still for sale and for how much.

BTW, on the subject of N/A vs boosted 2AZFE builds, you might get ~200whp MT (170whp AT) N/A for as little as $2000 but after that the costs rise exponentially with a relatively low ceiling on hp/tq. IMO if 180-200whp is enough for you, go N/A and live with it. If you want more power than that, boost is by far the more cost effective option, IMO.

You're welcome Bro. I'm really glad that I have an AT. Dyno numbers aren't the end-all, be-all some think. If I did a MT swap I bet my 1/4 ET's would go from 14.1-14.3 to 13.9-14.5 even though the dyno would read another 25whp. I'd have more wheelspin off the line, lose boost on the shifts and the increased driveline shock is more likely to break things. Then there's the extra torque steer and generally bad handling that comes with putting too much hp in a small FWD car. There are good reasons why the 275hp Speed 3 loses every comparison test to the 200hp VW GTI. The GTI is a very well balanced hot hatch and the Speed 3 is not. Sometimes less is more.

^ Good point. I don't see how alot of the tc guys drive 300+ whp fwd cars!I mean the LSD I put in really does help quite a bit when putting power down in the twisties, but....I'm N/A. I'd be curious to see how much it helps boosted guys.

I'd be very content with 250 wheel, or even a switchable tune from 200 whp to 300 ( autox and drag mode).

I doubt anyone makes a standalone that can do that though. :/

Thanks. AFAIK they only do rolling starts since they can't get off the line. I'm sure the LSD helps a lot, but over 300whp, it's still not enough. You could run multiple power levels with a boost controller and one good tune. A good 12psi tune should work equally well at any boost level from 0-12psi. All you have to do is change the boost level.

BTW, the Descendent kit owner quoted me $3000-3500 for his barely used kit with extras. I'm waiting to hear back on the details but it sounds like a great deal to me for a $5000+ kit with very few miles on it.

It's the full kit that costs $4700 new without a tune or gauges. The used kit includes a $500 pro tune from Churches, $200 AEM UEGO and $120 TRD boost gauges and even includes the dash panel that's been pre-cut to mount the gauges.
