Just out of interest, what mods do i need to see 400hp? and is the engine good for 400 without going forged?

 

Well you would have to start by moding your bank account ,at least £4,000 to get you going. I could be way out but I am sure some one will correct me if I am wrong.

 

Isn't 400 on his STI just a case of uprated fuel pump, bigger turbo and remap? 2k.

 

Don't know the spec but scooby clinic charge about £3.200 for stage 2 that gives approximately 340-360 bhp.

 

Bigger injectors or an adjustable fuel pressure reg
full exhaust system
decent panel filter
uprated fuel pump
set of 7B plugs
Bigger turbo.
Mapping

Thats pretty much it, if you buy it all second hand you can do 400 fairly cheap.

 

sounds quite feasible then

Bigger injectors or an adjustable fuel pressure reg - i have a sard RRFPR sat in the garage
full exhaust system - already on the car
decent panel filter - already on the car
uprated fuel pump - think the ppp came with one?
set of 7B plugs - not going to break the bank
Bigger turbo. - about the only thing i would need to source
Mapping - would be stupid changing a turbo and not having it mapped

finally would it not be sensible to have a front mount at that power and upgrading to an induction kit?

what are the standard engine good for?


ooooo i think i know what im going to be saving for this year

 

If your concerned about reliability then doing a half hearted job using second hand parts isn't the way to go IMO. But it does seem to be the case that the standard block and internals are up to the job.

 

to be honest i agree, ill end up sourcing most of it new

 

Think the TMIC is good up to 450, probably 500 going by the conservative advice on here! Pretty sure the pink injectors can run 400 but won't be far from maxing.

SC40
Plugs
OS Map

£1500

Deffo get a Walbro though.

 

please don't do this

Probably best to put fresh plugs in too

Not really.
Also, PPP'd cars generally never make the claimed bhp

Its the torque gains that you'll be most impressed with though.

 

To be fair they were refreshed when I bought the car(48,000 miles remap at 50,000miles), but changed them again at 60,000 miles. Same as what was in there, but wondered if I should have gone for the colder ones.

 

Do it if you want. It's your car.

 

i really dont want to, i was ignoring that comment lol

 

Yep, indeed.

Should put a VTA dump valve and fake roof vent on it too while he's at it.

 

Hell no, avoid a VTA, if you want pops and bangs from a bit of rich overrun spend more and get it mapped to do it.

 

I was being sarcastic about VTA

 

Me too.

 

400 is the new 300

 

That's cool I was kinda saying weight seems to be a big factor eg the 172 s and the glanza s
Weigh about say 950kg a blob weighs 1450 ish
That's quite a difference.
