Evening all, my car is an sti type uk 05 totally standard, ive recently purchased a cat back blitz nur spec r exhaust(not fitted) and was wondering what else i need to break the 300 barrier any info would be greatly appreciated cheers.

 

A remap, then you should be there.

 

is that all just a remap, what would be the cost of this roughly?
exscuse the dumbness im a beginner lol

 

Remap should set you back between £450 and £700 dependig on who you use.

The only other mod might be a fuel pump, but the one you have may be up to the job though

 

Id personally have a full de-cat, new fuel pump, and re-map, around 320psi or so

 

cheers for the help mate, anyone u could recommend i live nr lakeside in essex?

 

ditto to above plus panel filter greens or k&n
exhaust wise de cat or sports cat and you should see 320 min some have got to 350+

mappers i only use one that been andy.f but he's in port seton
only other i'd trust is bob rawle in swindon near your end of the woods

 

You have Mocom racing not too far. Highly recommended.

 

Is it worth the MOT failure risk/expense, when his target is 300BHP?

 

thats why i put both de cat and a sports cat. a sports cat is £300 decat £150 fuel pump £80 panel filter £45

so for an extra £275 to £425 than what he's already got i.e cat back exhaust is a small expense and you only need to remap once rather than desiding you want more later down the line costing more money

 

I think if you ask around theres always a way to pass an MOT..wink...wink...its who you know I reckon
