before u all start i know it would be better just getting a bigger engine I DONT WANT IT.
ok i am enquiring if anyone knows what mods can be done to boost the bhp of my astra. any help would be appreciated. if you are just gonna say get a bigger engine dont reply any other help would be gratefully appreciated.
De-ristrict airbox, fit performance panel filter. Get a decent cold air feed into the box.
Fit a full exhaust system(with a de-cat) which will probably fail the MOT as i seem to remember your car being Kreg.
They are some decent mods.
But if you wanna spend more
then you can go into things like headwork etc,cams.
But its probably not worth it on a 1.4
You can get twin weber carbs, but your car is injection so you would need to do quite a bit of work, removing ecu etc as carbs don't need it.
You would also need different inlet manifolds, throttle adaptors etc.
Quite a bit of work, but if your car was a carb engine they would give a good gain and pretty straightforward, you can also get a weber single carb.
But i would stick to your standard injection engine.
Not really worth bothering
rather than wasting money trying to tune that engine any, i would save for a 20xe, it really isnt worth it in such a heavy car, you need some decent pulling power in there (a 20xe)
If i ever do an engine change that will be the engine i will go for the xe, its the only engine that gives some proper performance.
You could pick up everything you need for about £400, then you and couple of mates could fit it. The XE will be about 150bhp, quite a jump from 80bhp.
lol.. rite mate webers involve a fair bit of work to fit.. and if u dont know what they are then leave that idea alone
best plan as ive done it so far...
fit a nova gte 4-2-1 exhaust manifold
Fit a astra 2.0 8v inlet manifold and use 1.8 injectors on the 2.0 fuel rail.
Block the idle valve holes in the inlet and fit a 1.6 8v throttle body off a mk3 astra
Fit new leads, plugs and fit a 1.7 diesel 8v camshaft and use a vernier pulley
turn the ron plug from 95 upside down to 98..use high octane fuel
and look at a superchip to raise the revlimit as the c14se can rev higher on its internals than its std 6800 limit

your engine dont have an airflow meter because it works off a map, it takes the throttle position and works out using its map how much air is coming in, and adds fuel accordingly, so it dont need an air flow meter
and airflow meter basically measures the air coming in through in air intake, tells the ECU how much air is coming in so that the ECU know how much fuel to add
Guys i dont know this is a friggin crazy idea... but i was thinkin this... what does an engine need to run, fuel, and oxygen, from the air. So what would happen if say you add a tank of oxygen, and a tank of high octane gas (Compressed Nitrogen or Propane or something similar), and installing 2 nozzle injectors just before the turbo in the air intake?. Then programming a simple EPROM chip circuit that maek sure that the ratio of oxygen that comes out is exactly that needed by the Propane/High octane fuel, to burn. Wouldn't it be much more highly efficient than fuel/AIR mixture?. Promoting full combustion = more power?. I have been thinking for ages about this idea... after all this is how rockets work .. they are propelled into space with their own oxygen to burn. Of course you would need programmer skills, mechanic skills, and some chemical expert to determine the best high octane gas to burn with the pure oxygen. It can act as a form "extra power" ... when someone needs more power... a switch is pressed and a mixture of oxygen and propane is rammed into the turbo instead of air from the cone filter. Ideas please. Current normal propane -air systems add 30-50 hp + 100-150 lb torque (www.bullydog.com)
by the way, can you specify from wich engines you took this parts?
Manifold
Cam
2.0 8V inlet manifold
Thanks!
