Right i got about 1k to spend on a corsa 1.8 sri.

What can i do with it to make it faster without turbo-charging it?


Was thinking of a full custom build exhaust with 4-2-1 manifold?


Wat you guys think??

decent suspension setup and some uprated pads for a start
if you can carry more speed round a bend your gonna be quicker
other than that decent freeflow exhaust/manifold and then some headwork


but consider suspension/brakes first though

oh and you'd be surprised the difference quality rubber can make as well

well like its other small block 16v brethren, the inlet is pretty restrictive, a mantezl power box would be good, coupled with a unichip and a decent exhaust, would give you a decent power increase

tyres suspension are a must. my 1200 nova on coilovers can just about keep with me brothers 1600 16v through the twisties, he tears away on the straights but i dont half catch him on the bends cause i can carry so much more speed round them.

Ive recently just fitted a Dbilas inlet manifold to my 1600 16v corsa and it has made a reasonable difference. I didnt buy it with the chip tho so hopefully when i can afford it i will get that aswell because i have to admit i did expect more of a power increase.
