Hi guys, i was just wondering what are the big differences between the 2 engines?? apart from the turbo what i already know about.

thanks rob

4bar instead of 3bar injectors, ecu's different. the intake manifold is the opposite way round, eg the air comes in from the right, twin intercoolers, im sure someone else will go into the internals for ya

And lower compression pistons (APX uses 20mm pin)

 

[rob_watti]

so which of these actually cause it to have more power?? also why when remapped does this engine give so much more??

thanks rob

 

[ianhg]

its the turbo that causes the main increase, plus the extra intercooler i guess

 

[GOLF GTTi]

And the lower compression allows higher boost to be maintained and greater fueling with the larger injectors....[].

 

[rob_watti]

so if i changed the injectors and turbo on mine and added a front mounted intercooler, would that see me with more power??

 

[ianhg]

a remap would be cheaper, but yes u can do that

 

[rob_watti]

yeh but with a remap on mine im looking at 220, but a remap on a a tt your looking at 280+

 

[ianhg]

i agree. 280bhp is a bit high, 265-270 is closer to it without doing anything more, its the K04 turbo

 

[rob_watti]

but i thought the k04 and the k03s are similar??

 

[GOLF GTTi]

K04 is bigger remember.....

 

[rob_watti]

so what is required to change to a k04?

 

[ianhg]

u cant just bolt it on im afraid, there is one for sale on ebay tho

 

[GOLF GTTi]

And you'll still be running a higher compression than a 225....

You can get a ko4 variant that fits straight on. You'll need larger injectors too.

 

[rob_watti]

what would be needed? a new manifold? starting to wonder whether it would be worth it now!!

 

[ianhg]

cheaper maybe to get a new engine and sell yours

 

[MkIV Turbo]

Prob better value for money just to get yourself the basic IHI turbo kit and that way you'll have a good 320 ish bhp. If you're not looking for as much power as the IHI offers then you should def consider the AM motorsport hybrid K04 turbo. More info on it can be found here: www.am-motorsport.co.uk. Also on a side note anyone who says they have over 280bhp on a 210/225 engine with standard K04 are being extremely optimistic.

ok thanks for the responses guys, was just wondering if that sort of power after a remap was available from my engine
