Max Horsepower?

[UnDrPrEsHaPnOi]

whats the max horsepower for the matrix/vibe? what do you guyz think?

[NovaResource]

AWD = 123-hpXR/Base = 130-hpXRS/GT = 181-hp

Do you the MAX HP the engine can handle on stock internals?If that's what you mean Toysport which handles nothing but moding Toyota engine has said that they feel the 1ZZ and 2ZZ can handle around 300HP before a problem might a raise. These engines are made very strong from info they have on there site. Once you get around the 250 mark as long as your not racing at every stop light and red lining the engine at every other stop light 300 should be ok. Realize if your really going to be driving the engine super hard most of the time that any engine can't handle all the time hard driving. This is like comparing apples to oranges but look at a NASCAR engine. 348 CI making around 750 HP. I'd say 15 to 30% of these engine driven hard none stop for 500 miles don't make it. Something fails. Also every engine is rebuilt after every race. If your drag racing a normal drag race wont last more than 30 seconds but if your drag racing 20 times every single day it adds up on your engine. Auto cross should be fine also if your doing it say one or 2 days a week, but every single day is going to be very hard on the engine, trany etc.quote:BUILDING THE ZZ ENGINES The aluminum block is hefty and casted really clean. It will allow the engine to produce massive horsepower over stock. Dimensionally they are bigger than the 4AGE, the engine family it is superceding. Block strengthening is possible, by pinning the cylinders to stabilize the bores. The crank is a lightweight design and so are the rods. The crank and rods are casted really well, stress-relief and shot-peen- will produce parts that look forged. The 2ZZGE has problems. Bent valves from missed shifts have been common. Sticking valve mechanism also cause unscheduled visits to the Toyota Dealers. Toyota is addressing these problems currently. We have forged pistons in stock and .5mm os available with deeper valve reliefs and a .5 higher compression. Here's another quote talking about the 1ZZ enginequote:The various FE series engines (using the FE head design) are the most thoroughly developed and purpose tuned Toyota power plants. In the USA, 98% of current models Toyotas use this engine/head design. The FE 4 valve per cylinder, narrow-angle Twin Cam heads (on the various Toyota blocks) are the reason for the amazing response and smoothness of the current generation Toyota motors. The high torque characteristic designed into these engines give the driver all the advantages of the Twin Cam head design- plus low-end torque and fuel economy. Torque is the reason why these engines respond quickly and smoothly. The performance band has been engineered to provide power from low RPM to the designated redline. There has been a lot of requests for parts and modifications for these engines, but unfortunately trying to raise the RPM band (or changing cams) will negate all the built-in attributes of these engines. A camshaft change to raise the power band higher, will result in the loss of low-end torque and idling problems. Drivability will suffer and the trade off will leave the customer with a compromised engine, trying to work against the ECU program and engine design. By comparison, the performance oriented GE versions of the same series engines, (if available on the sporty models)- offer about a 20% horsepower advantage- but at a loss in low RPM response and torque. The GE heads are more of the true Twin Cam design: wide-angle valves, long duration cams- suited for high RPM and high output- but at the sacrifice of throttle response in the lower RPM levels. There are improvements that can be made to the FE engines- but the Toyota engineered power band should not be altered. The ECU program and Camshaft profiles, if changed will result in a loss of drivability and risk internal damage. You cannot do a better job than Toyota on coaxing power from these series engines, and needless to say, stay street-legal. Upgrading these engines, is of course still possible: intake systems, exhaust components, ignition upgrades all help in fine-tuning these engines. The rule to follow and keep in mind is that all modifications are basically external in nature. The only exception being pistons- to increase or decrease compression- within the same RPM band. Turbocharging and/or supercharging will help- but keep in mind that based on the design parameters (again) these engines were designed for response- meaning lightweight internals: con rods/crankshaft (as compared to the sportier GE series engines). If your talking about stock HP then Resource answered your question. I do feel the 1ZZ engine are under rated. Here's a link that backs up and some what proves my point. Click Here
