I need 25 bhp extra (ABF)

[Seanl]

Yeah, my 8v sounded better than that today with no exhaust on!

mill the massive lips out in the throttle body that restrict air flow.
run a cold feed into the airbox and remove all the crap inside. there's a how to on here somewhere.
fast road cams if you can fit em yourself?

Works a treat on 8V/16V, loads of enlargement possible before you get into custom butterfly territory.

Does that really give much more bhp?

NO! sod all.

Have been researching the interwebs and it seems to be common thinking that add a tubular manfold, a decat, filter and remap and woot woot you have 20bhp.

Are you guys saying thats not the case then....

Correct, those mods will add extra power but not 20bhp.

[Len]

My remap was approx 2 bhp max!

20 to 25 bhp will need those already suggested plus either cams or throttle bodies, or both!
Mind you to make those work you need a fully gas flowed head and all that will cost you 2.5 to 3 grand.
That does include a new ECU to get best out of it!

NOS it is then 

Am I the only one that thinks nitros is the way to go? it's only 25bhp and it's not going to kill the engine. You just have to add more fuel at the same time. A good kit will include everything you need.

NOS FTW

Yawn , If you match and flow your engines breathing you will gain extra power from Expensive cams and Manifolds.
On some engines ive seen an extra 10/15 bhp from fully flowing and enlarging the breathing, add a Cam and you have 20/25
True, just sorting out the TB will not give you what you want, but you have to start somewhere and its mosty a time cost.
You can dream like most and wait for the 5k to do a proper engine conversion, or you can get stuck in and learn something which is portable to any combustion engine.

All very true, BUT just opening out/polishing the TB will give you sod all.
I know as I did it and tested it on same RR and got nowt!
