I have been running my uk classic my00 in its current state for about 8 months, and all has been well (touch wood). But cause i have got used to the power i want to go further.
I have already taken into account that the box might not last.
Currently running about 300/300 with following mods:

VF35
Walbro uprated pump
apexi avcr
standard top mount
440 injectors
full decat
Green panel filter
ecutek remap by paul at zen.

I went from my standard classic to full decat/filter and remap which was quite an improvement. Then i went to the stage above which was even better. I want the next stage to feel the same again .

What do you think i am going to need?

 

uprate ur intercooler and bigger tubo maybe bigger injectors

 

could anybody tell me how to fit a dump valve to my 98 scooby turbo

 

 

on standard fuel pressure your 440s wont go much above 320bhp so deffo need bigger injectors, the vf35 will max out around 350bhp so turbo wise above 350bhp its poss a td05 18g or 20g or even md321 but then you will need to start saving for a ppg/6 speed box and/or forged bottom end which ever comes first!!!

 

they will hit above that if yoru lucky.

on that spec i'd expect 320-330ish if you fitted a front mount, so might be an option, only problem with that is you may start to eat maf sensors, which if you do then its aftermarket ecu

 

Thanks for replies. Would i be better of going for 550cc or 650cc as they are about same price and wouldn't 650 need to run less duty?

 

650's will be overkill, you may be ok with the standard ones.
