hi,just wondering if any1 knows wether a 155 bottom end will fit on a 147?
Thanks Mike
Thanks Mike
ah right cool,so thats 2 replys sayin yeah it will fit
..simple reason i ask,.is cus a lad from near me sed i cant as my car is the s1 and the 155 version is the s2 and is different engine or sumthin..
im not exactly a mechanic but i pretty much fort they wud fit myself as it is the same engine..just easier to get more power gains startin from the 155 version..i got offered one for £90 thats all.
Cheers Mike
you wont get any power gains from the bottom end, they are exactly the same.im not exactly a mechanic but i pretty much fort they wud fit myself as it is the same engine..just easier to get more power gains startin from the 155 version..i got offered one for £90 thats all.
you wont get any power gains from the bottom end, they are exactly the same.
the power and torque difference is from the ecu's fueling and ignition map and the variable cam timing. none of that has anything to do with the bottom end. you would need to fit the head and ecu, but then you also need to fit the other bits and bobs to support it such as the loom and the fly by wire accelerator pedal arrangement and the throttlebody etc.
at the end of the day if u chip it, even if u get an extra 5-6% extra, ull feel it. the torque will go up. and ur acceleration will spread more accross the dial.
id say give her a good service, get a BMC CDA and chip it...will be enough i recon or u can go full out and supercharge it
its not long had a full service tbh,had new tyres,discs,pads,oil,filter and also a new cat when it went in for its mot 3 months ago so its all good
Gona get it chipped eventually i think,like a sed earlier on,just gona see what i can get out of this engine at the mo..
Cheers
To answer your thoughts Mike, probably best to sort the engines breathing out. Some better cold air feeds to the air box with either a panel or cone filter element. A cat back exhaust system. If you wanted more power but at a cost of less torque then removing the cat and possibly a faster flowing exhaust manifold would be the answer. Then possibly uprated cams. This would then need some sort of tweaking the ecu to uprate fuel and air ratio's
It all depends what power you want.
Most bigger bhp increases come at a loss of low down torque. Unless you are running a turbo or supercharger.
Just re read my last post. What I meant to say regarding chipping is that you as a driver will definately feel the difference although chips work better with mods.
Just that if you had two identicle cars and one had a 10bhp advantage then in real world terms there would not be a huge amount of difference if both were put head to head.
fitted a coupe turbo head to which block
the cams and fuel rail without the turbo wont help imo
