the head has some sharp edges in the ports and in combustion chambers around the valves
the owner copied the head and made some improvements and found + 25 hp
( head + new mapping )

 

is that from a early vw 2l 16v or the fsi>?

 

FSI Heads , otherwise it would be in the 16V forum

 

nicee.. do you got any pics of the head? im curious

 

Seat Toledo /Leon S2000 > WTCC/BTCC ( before they went TDI )
VW POLO S2000 > IRC
SKODA FABIA S2000 > IRC
VW F3 engine

All these use the N.A FSI engine as basis , its all in this tread

 

Pix from Page 1 of this thread.

 

Is there any reason a whole alloy blocked FSi can't be used. Is that the reason we are talking about mounting the heads on older blocks?

Could an alloy engine not have new pistons fitted without the swirl chambers and then port injection etc?

 

Both alloy and steel blocks can be used.
Alloy blocks are relativ new to us and we dont know yet where the limit is on these...

Many have already older type steel block engines, and by dropping a set pistons in and change the head, can make serious power as the STD head flows already very well.

With pistons similar as in post 44, ITB / port injected, it should work well

 

Looks good

 

i was at AET Turbo's yesterday and met Ronald Winters who runs in the Dutch Timeattack series.

He runs a MK1 TFSI on Megasquirt management. very interesting MK1 I'll post some pictures later.

Also found out that the TSFI has MAHLE Forged pistons fitted from the factory.

 

Has anyone got a clue how much would a second hand head go for?

 

200

 

Hm.. I'm looking in etka the part numbers 06F 103 285 and 06F 103 373 to confirm a head but it says there is not such part number.I'm i doing anything wrong? can anyone confirm?

 

i need the ETKA software , were do you get it from

cheers

 

F3 info appeared to be a bit of a side topic to this thread, so now shifted to here

 

woukd the FSI block bolt to a "classic" VAg box , eg 020, 02A etc?

 

Yes, 020, 02A, 02M all fit
IMO its the same alloy block as used in the ALT 20V
its just an evolution from 06A blocks

 

Thank you for that.

 

very interesting indeed...

So assuming you guys manage to physically mate up the head onto an ABF/9a/KR, whats the situation regarding ancilleries, mainly thinking exhaust manifold?

 

why use the ABF block , instead of the alloy block , or standard mk5 one?
