Astra A16XHT Engine Troubleshooting and Repair
In 2013 Opel introduced a replacement for the outgoing A16LET series, these are new modern turbo engines with direct injection to optimize fuel consumption, with balancer shafts for softer motor operation, a variable valve timing system is applied, a reliable timing chain is used, a small Garrett turbine blows as much as 1. 9 bar and practically from idle, in the basic version Eco Turbo, the motor gives out impressive 260 Nm, but the very shelf of the moment is narrow and already at 3200 the turbine is blown out… In the overboost mode, the turbine briefly blows up to 2.3 bar, the moment increases to 280Nm and is available up to 4250 rpm… There is also a version Performance Turbo with a reinforced piston, with an output of 200 hp. hp and with 280Nm of torque from 1650 to 3500 rpm, in overboost mode the torque is as much as 300Nm! The operating temperature of the engine, like most Opel engines, is 90C.
This is a very tractive grassroots motor for the city, and despite the high specific power, racers are unlikely to like it. Due to the novelty of the engine, the information on the shortcomings and weaknesses is very little, the article will be supplemented as information and feedback, do not switch).
Opel A16XHT 1.6 SIDI engine tuning
Chip tuning Opel Astra 1.6 SIDI turbo
The situation is like tuning any turbo engine, we go to the tuner and re-shim, they promise to increase power to ~210-220 hp. We put a straight-through exhaust on 63 pipe and cooler kit, 220-230 hp, there is no sense to move further. Given the size of the turbine and the pressure it provides, we can assume that chip-tuning will affect its life.
