  1. GTV TB: GT2560R & FMIC upgrade

    New oilcooler with custom air duct almost finished. Fasteners still have to sorted out and some paint applied. I found out that the OEM connections from pipe and fittings to the hose were very restrictive: just 8,2mm diameter while the pipes themselves are about 10mm ID With the new custom hoses all will be ID=10mm, perfect! Also the oilcooler has more area, 50 instead of 40mm thick and much more rows, so a much more effective cooler.

    Meanwhile a bigger Helmholtz resonator is fabricated to try to reduce exhaust drone further @ low revs.
  3. Nice colour! Well... regarding the radio: it depends on how it has been wired.. Normally the radio gets permanent power and switched power via the ignition key. This makes the radio switch off when the key is taken away. Maybe the former owner did not like that.... It is a pitty our Alfa's just have "ignition" and "start" on the starter key switch. They don't have an "accessory" position.
  4. GTV TB: GT2560R & FMIC upgrade

    I changed the fuelfilter and cut the old one to see if it was clogged but it looked all right (as I expected). The fabric of the filter was turned a bit grey.. So it was doing it's job just fine. No clogging at all. Also the filter is quite big so that is not a bad thing too. The TB is stuck in my garage now: I found that one of the hoses from the oilcooler was leaking (while replacing the right engine mount). Of course the connections on the cooler got haevely damaged while undoing the hoses.. So a new, bigger, Mocal oilcooler is on its way.... To be continued...

    Interesting questions... 😎 Btw MAF can also be used with Megasquirt. 🙂

    In that case the fuel filter would do its job and protect the fuel injectors. The fuel pump screen and fuel filter would be clogged up of course. But... I think it is not the case here: The original injectors are still in running on a Squadra Chip set with a bigger turbo. I am pretty sure it is just the injector size which is to small for the requested amount of fuel. They are in fact already smallish for the standard power (200hp). The Squadra Chip set max out the original turbo AND the standard injectors @ 235hp. Because of the bigger turbo the same power is already there at 5000/5500rpm instead of 6500rpm, that is what I think. It is the same ever since I drive it with this setup. Not really a problem, just a sympthom of the changes I made so far..
  7. GTV TB: GT2560R & FMIC upgrade

    I guess it is still the first fuel pump. But the car has seen just 130k, so it should be fine. Well... maybe the fuel filter is also still the original one! I have no idea, but it is clear that it has to be replaced anyway. I think the injectors max out at 5500rpm flat out. That means about 240hp I guess.. But, I am not going to invest time in the original motor management. It drives very well, so I leave it this way untill I install MS2.
  8. GTV TB: GT2560R & FMIC upgrade

    Well, all is still the same regarding engine and MM. I have about all to change to MS2 but most time is going into restauration work on a 1943 Dodge WC62, light 6x6 militairy truck. Lots of work! The TB runs very well with the standard MM and injectors but I cant go full throttle above 5500rpm because of leaning out. Maybe in the next year I can find some time to get the MS2 stuff working together with the 315cc injectors I have (instead of 189cc).
  9. GTV TB: GT2560R & FMIC upgrade

    This year I sold the Bilstein Fase1 front shocks and put a set Koni 24V Fase2 shocks instead: In combination with the Fase1 Eibach front springs the ride height is -15mm (instead of -30mm). Ride height is good, no bangs anymore etc., and in balance with the standard rear springs now. Also changed tires: Went from the Turkish Lassa's to Dulop, 225/40-18 front & 235/40-18 rear for now. Will change to all 235/40-18 when new rubber is needed. Got some trouble with idle speed: in the end it was at 2300rpm! After some checking and help from a member of the Dutch 916register it seemed to be a faulty Idle valve: so now his valve is on my car and all is good again: 850rpm Now asap get a new one and give the idle valve back to the owner.

    Yes, you can. But depends on the size of the hubs: TS or V6 shocks..

    YEAH! Another dead tread thanks to a discontinued Photobucket! Photobucket and the like should be banned from all forum!!

    Better use a 156 Q4 type drive train: That is a real permanent 4x4 system sending most of torque to the rear wheels via a TorSen central differential. Ancient 164 Q4 system works like the 4motion system from VW with Haldex couling, only sending torque to the rear wheels when traction at the front is already lost, in other words: when it is already too late.
  13. Hi from Rotterdam

    Welcome! I live near Rotterdam btw..
  14. 24V exhaust manifolds made to fit Spider 3.0 12V engine. - Primairies have 40% more flow area: 42mm vs 36mm - Secondairies have 28% more flow area: 54mm vs 47,5 No restrictive welds at the cilinderhead flange (unlike the original items). Not cheap....
