  1. 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....
  2. Alfa GTV CARBONara

    And how much weight does it save by just leaving them away?
  3. Big Power GTV 16V Turbo!

    Looks good! But there are also radial mounted Alfa Romeo discs with identical pistons as the Gtv 305mm ones (for 159). I am not sure about the disc diameter, could be 330..
  4. Big Power GTV 16V Turbo!

    I think you can also use the V6 shocks on the Coupe hubs (I guess they are the same as Fase1 12V and 155 V6 hubs). Best is to use Fase2 24V version with the right springs so you can use bigger wheels. Fase1 V6 12V shocks has longer springs and 15mm lower spring retainers on the shocks which makes a 225/40-18 a very tight fit. .
  5. GTV TB: GT2560R & FMIC upgrade

    They are called "Roma" so far I know. And they seem to be made from unobtainium. 8x18 ET38 5x98 225/40-18 Because of the high ET I needed 15mm spacers up front for looks AND to clear the Brembo's (so I end up with effectively ET23, the same as Sienna's with 5mm Spacer). On the rear I use 20mm spacers (=>ET18). I have seen four sets till now, all on Dutch cars, two on 156's, one on a GTV and one set I stumbled over in a shed on a breakers yard.. That last set is mine now, the only set I have seen in real life till now. Good possible that my set was on one of the cars I saw on the net.

    Did some 3000km to southern France in August. No cooling issues with the FMIC setup in combination with 1x 15" SPAL Fan (instead of 2x 10" OEM Fan) a standard 34mm radiator and airconditioning "ON" @ 30 Degrees Celsius. Also slow driving and much power on mountain passes. So... as expected.. no need for fancy alloy radiators and the removal of the airconditioning. Only a temperature controlled fan on the oil cooler would be not a bad idea: I think oil-cooling performance is next to nothing when driving slowly..
  7. GTV 2.0 Twin Spark Turbo

    Coincedence; I have exactly the same intercooler on my TB.. but didn't cut away anything from the crossmember. I used 54mm silicone hses and 55mm stainless steel piping. This is a bit bigger I see. He also kept the original radiator and airconditoner like me. What turbo is on it? Mine is running on 1,2 bar but I can't go higher than 5500rpm because from that point it is going to run lean because of the original MotorManagement and injectors. The Squadra Chips help a bit to give more fuel I guess.. but still not enough, the injectors run out of flow at 5500rpm so it will have +/-220-240hp @ 5500rpm I guess. When the rpm can go up the horses will go up accordingly..

    Last week I fitted Eibach -20mm springs @ the front: - in reality -30mm - looks are great /perfect now! - ride is a total dissapointment!
  9. GTV TB: GT2560R & FMIC upgrade

    Thanks guys, Speed tested @ 200km/h
  10. GTV TB: GT2560R & FMIC upgrade

    Back from snowboarding in Austria... And about 2000km mostly Autobahn later (mostly left lane ), the TB did a great job! Speeds mainly between 130-160km/h and just 1L fuel for every 10kms. I think that is not bad at all for a 23 year old car...
  11. GTV TB: GT2560R & FMIC upgrade

    Unfortunately there was a very strong drone on low revs till 3000 with the new exhaust setup which was unbareable. So last weekend I made a variant of a Helmholtz resonator which is adjustable in volume to see what gives best results... Right at the start it was MUCH beter!! Next is to play with the volume of the resonance chamber. ☺

    Soundcheck was not good possible yet.. Car is still on my carlift.. But it sounded not super loud (fortunately). Material is Stainless steel 304 (what else? )
  13. GTV TB: GT2560R & FMIC upgrade

    The Roma 8x18 rims are on.. this weekend started on the 4x70mm Ragazzon.. almost finished..

    The wideband lambda tells me that it is running lean at high revs (around 6000rpm). With normal driving it runs perfectly lambda 1 (well..14.8 instead of 14.7, just a little lean or a small fault in the measurement). Full boost till 5000/5500 is good at AFR 12, after that it starts to lean out via 13 @ 6000 and 15 @ 6500. (12 to 12.5 is good for full throttle). First thing is to change fuel filter.. Maybe it makes a difference.. and I want to change it anyway. ☺ After that the original MM has to make place for the MS2. First thing is installing the EGT probes. The bungs are already welded in just after the manifolds.
