engine internals - GTI and ED30
« on: May 09, 2009, 10:07:10 am »

Does the Gti have the same basic engine and internals as the ED30 ? in other words, is it possible to get the same power safely from the gti by bolting on a K04 etc and then getting it mapped ?

Cheers.

they are a little different but bolting on a K04 to the GTI engine gets similar results - sometimes better as the compression ratio is slightly different.

Theconpression ratio is a tiny bit less with the Ed30 pistons.. This means that you will not be able to run as much boost or timing with the GTI as you will get ore ignition earlier..

This translates to roughly 15hp less with a K04 on a GTI when compared to the Ed30

Thanks for all the replies gents.... got all the info I need for the time being cheers.

With the price difference between the Ed30 and the Gti think I'll be sticking with the Gti for now and modding it over time :smiley:


...do love the Ed30   :drool:

but don't think I can justify the extra beer tokens to the Mrs.
