things that would make a performance enthusiast scream. Lets start with the aerodynamic stuff: the upper grille is completely blocked. The lower grille is open but I have added a tray to prevent the air from spilling under the car. This forces all the air to go through the radiator. The tray...

this is my heavily modified US spec Saturn LW200. it can also make almost 170hp if I take all the mpg mods off.

Well the Corolla managed ONE lap before puking oil out of every possible location. Still I would not call it a failure but not a rousing success either. on the grid waiting to go Starting line And away we go (mosey) some corners handled surprisingly well and this is the last...

other than a decrease in acceleration the Estate doesn't notice

Believe it or not I am planning to tow another car with my estate. The car I will be towing is a Toyota corolla. This car is stripped out for racing and weighs in at about 700kg. I think I'll be OK towing as the estate has a towing capacity of 1000kg and a tongue weight of 180kg. the car will...

mine has the original: block, inlet,throttle body, cams, pistons, crank and rods what I've changed: exhaust mani, down pipe, cat, midpipe and backbox. Planned changes: inlet, throttlebody and cams

dyno results are in 139.6 wheel HP thats 169BHP folks and no tune on the original injectors. I'm pretty sure I'm at the limit of the standard inlet and injectors . I could eek out a touch more with a tune but I think this will do for now. Next up will be 24# injectors a tune and a 2.4 inlet...

here are the new flanges for my cat I used a brand new MIG so the welds are not perfect. this should flow a bit better than the OEM 1.75 inch stock parts

Sadly yes these 17kg Saab alloys are standard on my Saturn I want to replace them with something wider and lighter.

I have one restriction in the exhaust system left. I'll post pictures when I eliminate the last restriction.

I'm actually quite surprised that I'm doing as well as I am considering I started with just 130bhp. If I can get some tuning this estate may top the bolt on power gains board.

I have pulled the Short ram intake and replaced it with the standard air box (fully de-restricted) and a good 3in cold air feed. I have gone from 145 bhp to 166 bhp by just swapping this back. Next up is one small restriction in the exhaust. I have one place where the original flanges are used...

What spark plugs are you using? these cars are very temperamental about what plugs you put in them

no there is no valve in the inlet other than the throttle body.

20k service intervals are awful long and they may have contributed to the cam failure. If this were my car the service intervals would never exceed 5k and I would strongly recommend on your next engine/car stick to shorter intervals. The oil may say it's good for 20k but your filter isn't.

I had an airbox shipped it cost ₤30 for the shipping on a ₤5 box and at the time the american dollar was pretty weak against the pound.

I decided to try this for fun and was very surprised with the results. I have a HP gauge in my aftermarket multi function display. I decided to compare a Short ram intake verses a fully modified air box. First up the short ram this is in an automatic car (we didn't get the manual here in the US)...

that spoiler is going to cost a mint to ship so don't kill yourself.

I would check the timing again I've done this a time or two and went mad thinking something had gone horribly wrong. I found I had missed by one tooth and that melted the cat so check your timing again it could be just that simple.

Just spoke with one of the guys at HPTuners.com and he said they do cover some Vauxhall ECM's to find out if they cover your car contact them [email protected] they will need make model engine and the code # on your computer. this may open up a whole new world of tuning for the VX brand.
