Hello guys am new on here so please go easy on me I thought I knew what I was doing when modifying my golf but I was wrong when I spoke to some one from r-tech so have joint this forum for some help,
My car is a mk4 golf 1.8t agu engine code, I bought a ko3s turbo which wanted a rebuild so took it to http://www.turbocentreuk.co.uk/ they recommended me to go hybrid so which I did which consist of ko3s compressor wheel and rs6 turbine wheel I have been told this is not the right combo any body has any advice on this I can't take it back now as its already fitted to the car
Mods I have done:
Ko3s hybrid turbo (supposedly)
Creation Motorsport tip ( I have been told these are restricted 200bhp because of they flow what I was told by r-tech any body else has any info on this matter
HKS mushroom air filter
eBay front mount intercooler 2inch pipe work are these any good
N75 j version have been told standard is better
Turbosmart bov
2.5 sport decat pipe mated to miltek exhaust system
Solid flywheel and vr6 clutch
Parts I have bought:
Walbro 255 fuel pump
Saab injectors
Vr6 maf
What do you guys think to my set up as I rang r-tech up to book my car in for a custom remap as I wanted to hit about 260bhp and he said to do abit more research and directed me to this forum what do you guys think I need to change or improve on to make 260bhp
Will really appreciate you advice guys

Any help guy I've got the car booked in for a remap at rs tuning in Leeds this week costing £350 just want your advice should I cancel it or go for it with the mods I have above am looking at 260bhp or do you think I will be disappointed with the way I have it set up
Thanks

You'll struggle to see 260bhp with your current spec...
Mods I have done:
Ko3s hybrid turbo (supposedly)
Creation Motorsport tip ( I have been told these are restricted 200bhp because of they flow what I was told by r-tech any body else has any info on this matter - You'll need a better TIP for 260bhp
HKS mushroom air filter - These are pretty small aren't they?
eBay front mount intercooler 2inch pipe work are these any good - Pipework will be way too restrictive, you'll struggle to see much over 200bhp
N75 j version have been told standard is better
Turbosmart bov - Get rid of this for a Forge recirc valve.
2.5 sport decat pipe mated to miltek exhaust system
Solid flywheel and vr6 clutch
Parts I have bought:
Walbro 255 fuel pump
Saab injectors
Vr6 maf

+1 on the above.
as for the turbo, im sure ive seen that turbo set up on a few cars and them seeing just under 300 bhp with the correct supporting mods.

2.5" intercooler pipe work
Forge recirc valve
80mm tip (sfs or badger 5)
Standard air box or s2000 filter
-
Thankyou guys for the replies, will ring rs tuning in morning to re-book for another day
Where's best place to buy the sfs tip
Where can I buy just the 2.5inch pipe work
I will change to standard air filter box with piper cross panel filter will that be ok
Also will change bov to forge
I've been reading up will I have to change my actuator to a forge one as I've read standard are week
Thanks
-
Prob eBay for the tip
Ash (autosiliconehoses) if your gonna build it yourself (check my build thread)
Piper cross in stnd box will be fine but you'll need a bigger air intake (dsg I think will be ok but prob a 3" aftermarket pipe will be better)
Yeah a forge actuator will be best but if they built it with a k04 actuator it should be ok :wink:
-
What is a dsg intake? Sorry for the noob question
My actuator is a standard ko3s one so looks like will have to go for forge on
If I buy sfs 3" tip can I fit my vr6 maf to this with my standard maf sensor will modify the air box to make it all fit will the car run ok like this or won't it or is it best to fit it on the day of the remap
-
Here's the info on the dsg intake:
http://www.golfgtiforum.co.uk/index.php?topic=87356.0
I plastic welded a 3" vent to my airbox instead and ran ducting down to the bumper, seems to work ok too.
I'd leave the injectors and maf till the day of the map

i might be selling my ko3s forge actuator if your interested
