Auto Tuning VAZ Oct 13 Tuning VAZ 2109 | Conversion of a carburetor engine into a 16 valve injection Tuning VAZ » Engine Initial state: car VAZ 2109, engine 083, carburetor. The goal is to convert it into an injection 16 valve (by installing a cylinder head block from 2112 on 083). I rode a nine, already redesigned for 16v (but not yet tuned by the program). Impressions compared to my carbovoy 99: the very lows are slightly worse (up to about 2000), then the thrust increases sharply - the acceleration in 4th gear is similar in dynamics to mine in the third (that is, the difference is very noticeable). The converted engine was still in the running-in period, so it didn’t spin a lot (and the tachometer didn’t work for it ;-)), but subjectively, it was very easy to spin up to 5000 rpm on the fourth. And of course the sound ... you just need to hear it (it has a completely direct outlet, zero) - greedy suction of air by the motor. In general, very impressed. What you need: 16v cylinder head assembled with all manifolds and a receiver, DMRV, MZ, DD, throttle pipe assembled with DPDZ, IAC, Pants with DC, thermostat with sensor, rollers (both), r / v pulleys, timing cover assembly, DF, controller VS 5.1 ...- 42, wiring to the engine compartment and to the injectors, as well as explosive wires, gas tank assembly, fuel lines and pipes, oil level indicator, ramp with injectors, generator, DPKV, DS, wiring to BN, brackets generator and tensioner, connecting rods, pistons, rings and pins, pulley of KV and generator, oil level sensor, spider, oil pump housing with outflow under DPKV. All work can be done without removing the unit (although, of course, it is more convenient to do the work on the removed engine). Work order: 1. We remove the cylinder head, the old gas tank, fuel lines, dismantle the ignition system (coil, distributor, switch, EPHH), remove the old generator, pulleys, belts, thermostat. We remove the gas tank, fuel lines Instead of the old one, we will install a gas tank from the injection model. The difference between the gas tank and the injection model is that an electric gas pump is located in it.

Disconnect all antifreeze pipes. Some of the antifreeze pipes will remain, some will have to be purchased. While it is best to buy a simple 2112 hose kit, it is inexpensive. 3. Remove the pallet (if the unit is not removed). Remove the connecting rods with pistons and install new pistons from 2112 (with floating fingers), connecting rods from 2110. This must be done, since the new pistons have recesses for the 16v cylinder head valves and are designed for a high compression ratio. 4. We change the oil pump to an oil pump with an outflow for the crankshaft position sensor (you can change not the entire oil pump assembly, but only its cover, it is advisable to get a strong hexagon to remove the cover from the oil pump housing). 5. We change the coolant pipe to a pipe from 2112. New antifreeze pipes are purchased and replaced from 2110 (set). (from the stove and expansion tank to the radiator - you can leave the old pipes). The fan switch is no longer needed, since everything is controlled from the brain. Photo of an old pipe: Photo of the new pipe: 6. Prepare the 16v cylinder head for installation. The seats are the same, but in the new cylinder head, the holes for the mounting bolts need to be expanded with a drill by 12. The bolts from 083 are shortened to the length of the bolts from 2112. Photo of the already cut cylinder head bolts to the block 7. We lay the fuel lines from the corresponding injection model (08, 99). We are laying in standard places. 8. We lay the wiring on the fuel tank (buy) and connect the fuel tank to the highways and install it in place. The wiring to the fuel pump comes from the brain. The fuel sensor wiring remains old. 9. When laying new wiring, it will have to be lengthened if laid in a regular place. If you cut a hole (in the panel of the engine compartment) like in a dozen, then you don't need to lengthen anything. 10.In the block we drill a hole for the knock sensor and cut the thread to 8. 11. Change the pump to a new one from 2112 12. Change the crankcase ventilation breather to 2112. (purchased in addition with the oil level dipstick from 2112). Photo of the new breather: 13. We put the cylinder head, tighten the bolts of its fastening (we change the gasket to a new one from 2112). (In the cylinder head, it is advisable to combine the channels with the collectors, that is, remove the protrusions at the junction, go through the channels with a roller cutter, at the same time the channels can be slightly expanded - but this is not for everybody). 14. Install a new thermostat from 21082 (injection model) 15. Connect all antifreeze pipes 16. Install the rear timing cover and pulleys, rollers from 2112. Install the belt according to the marks. We install the generator, the generator drive pulley (on the crankshaft). Alternator mount (upper tensioner and lower bracket) 21082 (from the injector eight). That is, we buy a generator + tensioner + bracket + generator bolt (inserted into the lower bracket) from 21082 engine. Photo of the new generator: How the generator was attached: We tighten the two lower holes with bolts from the old one, the upper hole is not used (there is no hole on the block, but two connections are enough). Under the upper tensioner one bolt from the old one + the new one is the same, there are holes for it on the block. 17. Install all the sensors (the crankshaft position sensor (DPKV on the oil pump cover), the phase sensor - near the intake camshaft pulley, the knock sensor (in the block), the temperature sensor (in the thermostat and in the block), the sensor in the head - we leave the old one (and the sensor oil pressure is also old), and in the thermostat we buy a new sensor from the injector. 18. Install the valve cover on the sealant. Install the ignition module, receiver, spark plug wires, throttle, corrugation, lay the wiring to the sensors. Install the air filter. New gas cable from 21103. 19. Installing a new spider (exhaust manifold, pants), resonator. The old one can only leave the muffler. 20. Fill in oil, antifreeze, gasoline. We connect the wiring in the cabin to the ignition switch and dashboard That's all. The result under the hood (a completely different, nice-looking engine, it's not a shame to show it to your friends. 0 Comment (s) " Similar news This entry was posted by dez and has been viewed 20780 times and left 0 comments (s). leave a comment Subscribe to updates Welcome Guest !
