It takes a while to warm up that way, but works well enough for my purposes. I had previously modified my firewall coolant pipe as shown below. Due to the ability to provide better cooling of air-fuel mixture by direct fuel injection into the combustion chamber, the compression ratio was increased up to 11. Still, the power increase is substantial and the torque increase makes all the difference in the world in how the car drives around town. We offset ground them to get the required stroke. I started with a stock style setup, adding a port to connect to the firewall filler.
You can also see my fuel filter mounted stock regulator, my first fuel system iteration. The intake camshafts were driven by the crankshaft via the primary timing chain. If anyone knows of another harness option that is similar to the Rav4 harness let me know. There are steel-laminate type head gaskets between cylinder banks and heads. The 10 Best Engines winners for 2016 should be announced in late December 2015 and the awards will be presented at a ceremony in Detroit during the North American International Auto Show press conferences in January 2016. Years Peak power Peak torque 3.
This also requires a hole be drilled in the firewall above and forward of the side vent to run the wire through. In the event of cylinder wall damage scoring, deep protrusions, etc , the entire cylinder block must be replaced. Bought in bulk they are pretty cheap, but they can be quite expensive at your local hardware store, so plan ahead! My car is primarily a summer car, and my heater is plumbed into the main coolant pipes at the front of the car. This car is otherwise 100% stock and we suspect the cat is a little bit clogged up based on the before dyno numbers. The manufacturer replaced that rubber part by a metal pipe. Some relevant details from wikipedia are below: quote: Before commencing production of the Aurion, Toyota Australia manufactured the full-size Avalon model at its Altona plant in Melbourne until June 2005.
It will be safe enough. George Reply to Knightshade, What you are saying about the injection isn't what Lexus tech tells me, however when the injection works isn't important to me!!! However, if you do want to add an external oil cooler, this is how I went about it. Also, turbocharged motors on the track can be a reliability nightmare. Personally, I love the way it sounds, and the way it free-revs with a lightweight flywheel is amazing. Lastly, the main power wire from the alternator needs to be shortened and a new ring terminal crimped onto the end. By the way, the Lotus Evora S and Exige S were equipped exactly with that engine. I used zip ties to keep the wires bundled in their approximate shape.
The thin walls of the cylinder liners make the engine impossible to bore the block. Location of required bosses marked: Pictures below show notches cut in bellhousing, and new threaded boss welded in place. I was always of the impression that the block mating surface was identical, hence no problems in that respect fitting a Gen3 trans to a Gen2 block. First step on the wiring is to strip the harness sheathing back to the edge of the motor and start removing wires that won't be used. If you purchased a motor with the factory oil cooler that should be more than sufficient for any street use, and even for some moderate track use. My current goal is ~320rwhp, and I have a definite budget in mind.
You also have to install one M12X1. For 2008, this was an extremely technologically advanced motor for an econobox. If doing your own wiring, do yourself a favor and buy a selection of good quality automotive wire in various wire colors on eBay or somewhere. The V-angle between cylinder banks is 60 degrees. A low rate of idle run.
The wire to the stock oil pressure switch needed to be extended to reach the new location, and you can also see the insulating sleeve that I added to protect that and the crank sensor wires where they pass near the header. These produce 241 kilowatts 323 hp and 400 newton metres 295 ft·lbf of power and torque respectively, and have a combined fuel economy of 10. With these special thin liners it is impossible to bore the block. There is a video of this dyno pull on So, Was It Worth It? Although the engine is relatively the same, but head design and fuel management is different, it would not be cost effective to change the system. The main function of the port injection is to improve cold-start drivability, not tend to improve power. Lotus uses this in their Evora with a 7500rpm limiter, which goes to show how overbuilt it is.
At low engine speeds and high loads, however, direct injection is inferior to port injection in forming a homogeneous air-fuel mixture where there is little time to form a homogeneous mixture — from the time fuel is injected until ignition occurs — due to mixture stratification in the combustion chamber. One minor, not strictly necessary, but definitely nice modification to make while doing the swap is to the dipstick tube. Speaking of wiring harnesses, remember how I said the Rav4 harness was the one to get? The aluminum alloy pistons have resin-coated skirts to reduce friction. The liners itself are cast into the aluminum engine block. It can be easily solved by cleansing the throttle body. Between the filter and the engine, a P-clamp secures the fuel line to the strut tower.
I actually built it so that it touched the oil pan in a couple of places, which I will deal with later. Sleeves have a flange on top that is used for stopping the sleeves from moving. The valve clearance is automatically adjusted via hydraulic lash adjusters tappets. Of the two four-cylinder motors, the latter is united with Toyota's five-speed U250E automatic, with the U241E four-speed unit reserved for the 2. Finally, there is a tab on the upper oil pan that must be cut off to clear the fwd transmission mount. You should do it once in 30,000 miles 50,000 km of mileage. The Intake gear is timed in relation to the crankshaft via the timing chain; the exhaust gear is timed in relation to the intake gear via the No.
You will also need a rubber boot to cover the end of main power cable. We have not done this build yet so the exact length is unknown. The centrally positioned spark plug would ignite the richer mixture during the expansion stroke. You can either modify the stock cruise control switch, or install a secondary switch and push button as I did. As someone mentioned before, you may want to change your car instead.
