Hi Newbie, here rollin' with a 9-3 aero 2.0t hot. OK the question subject is can I put a 92 - X bonnet on my aero or am I being crazy? I admit I am lazy so what I don't want to do is work my socks off, for a criss ride. I just wanna give the'metal', a blow over powder coat and lacquer clear thanx, an deep 3 coat. I thought the deep scoop would help the engine/Ecu airflow. Views?

It’s a different car. The 9-2X is a rebadged Subaru Impreza.

Really a different car? I thought the front end of the 92 an 93''s were the same drop front. P'eed off here already lol. I thought a bit of scrapyard challenge, a bodyshop magic, hey presto cooking with gas. No? I really think that at 100 squids a time to practice on a bonnet is a little bit expensive cos my bonnet ain't coming off unless the replacement is sick. If I am full of it please tell me, cos its Xmas an Nyear to actually have a car I wanna mix it with. Previous history. Escorts - Xr3/1.8s - 318, 325ci beemer, 2.0 focus, saab arc and then Wow mint Aero 9-3 so here I am.

Yes, a very different car.

The 9-2x is a restyled Imprezza, often affectionately called a Saabaru.

In your position, if I really wanted a scoop, I might be tempted to buy a used 9-3 bonnet, a 9-2X/Imprezza scoop and do some fabrication. Then plastidip the resulting bonnet (hood?) in matte black or similar.

The imprezza had that scoop to direct a small amount of air to the intercooler which was sat on top of the engine. Its pretty poor design, and when modding scoobys one of the first things to do is swap out to a front mount intercooler in the bumper.

Adding a small vent to direct air over the engine is going to do SFA to the engine temps on a watercooled engine, and will increase the air pressure in the engine bay reducing the effectiveness of the radiator. That extra air all has to go out the bottom which increases the pressure under the car and affects the handling. Look at the effects of fitting a full undertray to a race car for an example of that.

Much better to stick an exit vent just behind the slam panel to get more air through the radiator and out of the engine bay via the top rather than underneath.

Ok then back to the drawing board, dropping the scoop for a clean air induction tunnel? Induction kits are rubbish an just give me ecl problems, so how do you get cold air to engine without cooking it near the brakes? Discuss?

If you want to improve performance, then the usual options are to explore the do88 intercooler, a 3 inch downpipe with a sport cat. Followed by a custom tune form Karl at Noobtune. www.noobtune.co,uk

There have been many misconceptions over things like bonnet vents and scoops. Almost all will make things worse. The engine is mainly cooled by the water and oil, not by the air flowing over it. So your aim should be directed to improving the air flowing through the radiator. Any holes in the bonnet will in effect by-pass the radiator and reduce the airflow through the radiator.

There have been other common errors trying to "cool" the engine. One is removing the blanking pieces in the side grilles in the front of the car. This makes a couple of huge holes either side of the radiator and can ruin the cooling.

Saab did a good job of designing the cooling. It's difficult to improve it. The only proven way is to try and reduce the air pressure under the bonnet. this can be done by making holes in an area of the body which almost always guarantees low pressure outside. The only place is really in the wings behind the front wheels. Look at jaguar and Aston Martin, etc.

So it''s an intercooler then, good to know that. I have seen some for buttons (avoid or snap up?) The main cost seems to be the angled pipes 2.5 - 3.0 to the throttle section? Why so dear? Would a new replacement of the om just be the best shot? I see lots of people (American cousins) moving radiators to get oversize units in the front scoop, mine is lowered not much but enough. Do you guys think just a straight new one would buy me some time, I just can't cut into the car! I just got it back together. Discuss?
