2.0L 16V FSI Head Design

Hmmm would a FSl Head fit on an ABF Block ?

Looks possible to me .

 

yep

 

That FSI head has the extra 3 oil drains at the back of the head. It is more likely to fit on an 06X or early 20v type block. Saves blocking oil drains in the head.
Early 20v ADR1.8 engine (intermediate shaft type) would be a candidate with a 2.0 crank and bore.

 

Yes the 3 oil drains at the back of the head in between 2,3 cylinders that can be overcome easily.

Just need to find a head now.

 

It would be similar to an ABA 20v build; weld or pipe plug them.

 

Just been looking at the spec on the AXW FSI Engine and its 11.5 compression as standard also the variable inlet manifold is an interesting set up.

 

i tried a FSI head on an ABF block and it drops straight on, apart from the oil return holes

- The cam pulley is about 7 mm more outwards than on the ABF head.
with an adjustable pulley this can be corrected so they line up with the crank and intermediate shaft pulleys

- The timing belt is a few teeth to short to fit straight on, the belt tensioner has to move a bit closer to the back of the head ( towards exhaust side )
OR if there is a belt with a few teeth more ? TDI ?

- FSI cilinder head bolts are are only 10mm / ABF 11 mm
ARP head studs for FSI are 134 mm long
both FSI and 20V ADR are 140mm from deck to camshaft center / valve cover
FSI 75 mm from bolt seat to deck / 20V ADR 78mm
ARP bolts are available for the 20V heads with 10 mm bolts to go on a 11 mm block
most likely these can be used with little or no modification

 

Good info HPR.
That sounds like it would be easier to source an 06X block. They have the extra 3 oil drains in the block, they drop the IM shaft, and also have the chain driven oil pump in the sump. This pushes the timing belt out a little too. Head studs are the right thread.

 

058 / ADR-AEB blocks with ext wp/intermediate shaft have also the 3 oil return holes
06F FSI blocks have an oilpump / balanceshaft unit ( about 7 kg)
but this can be replaced with a 06A /B oil pump only
Using the N.A FSI alloy block saves around 20kg
FSI blocks also have an ovalised crank pulley to take some tension off the belt

Forget to use direct injection, the oem ECU is far too complex to tweak as we could with previous engines/ECU.
Just mount dummy injectors to close the FSI injector holes.
Run it port injected ,manifold with ITB`s on some aftermarket ECU

These heads flow std already as much as a good ported 16V Head
on std size valves

 

HPR, has someone made a piston for a port injected set up?
I still have the stock 82.5 N/A pistons...

 

I need to get one of these heads. Postage to Irl is insane though. 50stg plus.

 

just have some custom made wossner pistons from a lamborghini galardo
sent me an email

 

Good stuff, not there yet but glad there is even still more room to grow. What about having these alloy blocks overbored? Im not sure what limit the alloy block has and what coating process for the bore. I definitely want the correct pistons and would love to give it some more at the same time.

 

Pistons are 83.00 mm
IMO would not go any bigger than 83.5 on alloy blocks

 

To expand on this.
You can drill the head from 10mm to as wide as 12mm for those who want to use the ALH block (incase you allready have 159mm rods).
ARP has head bolts available in M10 , M11 and M12 for use with a 9A 16V head.

Getting the camshaft gear to work is going to be a little tricky considering the OEM FSI camshaft has a taper in it so some welding and lathe work is required but it all depends if you want an FSI head THAT bad.
I will state this anywhere on any forum. You will never get a higher flowing VW head than this baby. The future is here.....

 

someone stated that there are two types of fsi heads.what are the differences?

 

N.A > FSI head / Turbo >TFSI head

inlet flange is for both the same
inlet port on FSI has more radius under the valve ,
TFSI has a straighter port

bolt pattern on exhaust flange and exhaust porting is different too

 

As always HPR is on the money.

The N/A 2.0 FSI head uses the same exhaust bolt pattern as the B5 Audi S4 2.7TT cylinder heads or the ALT's whereas the newer FSI/TSI 2.0 Turbo motors use the angled exhaust studs for locking.

Here are some pics of our CNC'ed ports.

Are this pics of any help.
Only see a difference with the intake manifolds.
Can't really see the radius under the valve from this pics as HPR said.

 

any updates on this? anyone got part numbers for the heads? na/turbo etc..
