basically the calculation for the 7.5mm elements is:

60 EUR/element + 8 EUR/delivery valve

I personally got a perfect pump within almost shipping time (< 3 days in the shop) and additionally 500 EUR from PP D in Finland, including external adjustment possibility.
This was a 6 cyl. M-turbo pump.

The result is a plug and run IP without any idle or whatever issues that gives good power (not dynod yet) without smoke and without turbo lag.
The rest of the engine is still stock.
Economy is better by approx. 20% even when using the extra power.

What about MW pump from a 617? Seems like it would be hard to find an M pump in the states ... dont see many NA 617's floating around anymore.

I also made MW elements with 6.5mm.
But MWs are rare over here and the number of people asking for MW was poor.
On top the MW elements are made of used 5.5mm with a new plunger and matched into the cylinder.
Way more machine hours resulted in 75 EUR/element.
The last set I sold in November but the buyer gave it back as his shop told him that the elements were used...
If you want big MW elements follow he 10mm threat or contact OM616 member.

This is why I am going with Myna. The prices for the labor on bench testing makes ZERO sense to me. There is an STD member who swapped the elements out himself. Now that I have 2 dead spare IP's I plan on giving it a spin, particularly if I can make my own test bench, which seems fairly trivial.

The group buy on the bakerfield shop seems way better than this guy here in nor cal. He seems way too money hungery so im going with Deliveryvalve's guy in bakersfield.

Are you going to try the MW or the M pump?
