I have an Astra GTE 1.8 8v.
I'm going to do the following mod's to my engine, and I was wondering what...
1. The current bhp is efore adding these
2. What the new bhp will be
3. If I'd notice any difference
Here's the Mods
1. JANSPEED Sports man - This should be the best I think...
2. Twin 2" Peco Rear Box
3. K&N 57i induction filter
I don't have access to a rolling road, so I can only guess.
I'm hoping I'll be about 120bhp.
