Hi all
Quick post......... anyone tell me what sort of power i will be looking at with running a ko4-001 turbo? iv just purchased one and going to fit it this weekend,
I know it will need a decent map for it to get the full potential out of it, ( going awesome gti for that )
1.8t
forge 007p recirc
ko4 turbo
remap?
what bhp am i looking at?
already running 210bhp out of a ko3 turbo so expecting a bit more..............
-
intercooler?
bigger injectors?
bigger maf?
go to r tech for mapping. :rolleyes:
210 outa a ko3?? :lipsrsealed: you sure?
-
You need a full turbo back exhaust for the best gains too.
-
210 from ko3 is optimistic as they usually 185 -200 tops
you had it on rollers to prove with a print out :undecided:

You wont be getting 210bhp out of a k03, 200 bhp max and that would be with all the supporting mods.
With what supporting mods you have a the k04-001 I reckon you will get around 230bhp.
To get the most out of it you need to get a full turbo back exhaust, TIP, larger maf, injectors and maybe fuel pump then you would be seeing around the 245bhp mark.

yeh mate iv got the print out 208 it is,
iv got a janspeed catback,
defo need bigger injectors,
what sort of intercooler is best? heard loads of good things about the THS or what ever its called.
what bhp would i be looking at the ko4 remap fuill exhaust de-cat? 240? maybe more?
-
if it is running that from ko3 that is very good
-
Yeah THS is the one to go for
-
yeh mate iv got the print out, i thought it was only capable to 200bhp, i was actually going to take it back and see for myself, as i know some rollers to be abit wrong lol,
but what i have is....
catback janspeed exhaust, ( decat next )
forge 007p recirc valve
ko4 to go on this weekend,
then a map
wheres the best place to get bigger injectors from?
-
what engine code is your car?
-
i think its the agu, ill double check later,
whats the best move to make next regarding the KO4?
how much are injectors?
maf?
how much is a map from r tech? and where is it located?
-
if hes running ko3 it will be agu or arz
-
iv got some 310cc injectors for a AGU
ko4-022 like me :cool:
maf- off a VR6 mk3 golf
map is 390+fuel in Leicestershire
-
Unless your going full out (like Toby 300+) a K04 seems not much more benefit than a decent mapped K03s and you need a boat load of extra mods and money
-
ok no worries.......
how much are the injectors mate?
just bought the ko4 thats all, that will be bolted on this weekend,
after some good brakes too? anyone got any for sale?
not going balls out like Toby, lol but id be happy with 250bhp, is this achievable? with a janspeed catback, forge 007p, and a decent map?
-
Like the others have said you need better supporting mods really.
without the supporting mods I very much doubt you would get 250
You really need a 3" turbo back system (preferably a decat, but then you have emissions on the MOT to worry about)
bigger injectors
bigger fuel pump
FMIC (Ideally)
3" MAF and different TIP
and thats a lot of money and work
-
as said you will need the supporting mods if it is an AGU to get 240+ and a custom map.. Awesome use APR maps and while there is a file for the K04-001 I'm not sure if it takes into account bigger injectors and MAF sensors.
A guy on here has 250bhp & 311ft-lb from a k04-001 and forge actuator with supporting mods and that was with a restrictive exhaust!. A decent flowing exhaust and ported manifold 260+ should be possible.
-
Take a look at my buid thread mate not up today's yet but got all my mods listed at the start :smiley:
As said I have got 250 butt exhaust is restricting me massivly can see it on the graph, feel it and hear, my set up is pretty much the same as what nick at r tech had apart from the milltek exhaust which is next on my list an he was gettin about 280 bhp!

You can see how my torque peaks holds a tiny bit and then drops pretty much straight away, that's because my exhaust gasses can't get out quick enough so hopin to hold that a little more after gettin a good system.
I would go ths front mounted and injectors I got off of eBay :grin: although bam injectors won't fit yours as its agu.
As said you want a tip really and try and port out your exhaust manifold when doing your turbo, will help spin it up a little faster :wink:
