Opel Tinkerer and Rescuer
This solves all those things and has a port on the back ( see new pics on first post ). So you can get heat loike stock along upper part of head, or use the lower port.As previously stated on Facebook, I'm in for one. Even though I have my previous 1.9 style + adapter + chrome and will receive the FI one back from the chromers in about a month.
I wish I had the engine and the FI stuff here to do comparisons and offer alternative ideas. As I see it there's 2 issues preventing the use of the 1.9 style + adapter: Clearance between the housing and the throttle assembly and the seemingly anal need for super accurate temperature reading for the FI.
For one thing, is the clearance issue still an issue with the use of the new smaller throttle body? I live where it's cold and I want the heater function and I want it to be simple like it is now with the 1.9 housing + adapter. If I have to use the cockamamie FI housing, I'll have to use the rear block outlet for the heater(or a T-fitting in a hose somewhere), which comes uncomfortably close to the exhaust. I have bypass holes in my present thermostat and the whole system presently works great. If
If that's cleared up by the use of the shorter TB assembly and I have clearance, bypass, and heater function, then that leaves just the temperature sensing for the FI to be straightened out. Okay, I'm not holding water in my engine until just the water in the block is up to full operating temp and the thermostat starts to open, instead, all the water in my system slowly mixes until it's all at operating temp. If I didn't have constantly active bypass, as soon as the engine water gets hot enough to open the thermostat, that water will drop in temp as it mixes with the cold water in the external hoses and the radiator. This means a flux in temp will happen, which the FI may react to and adjust for. If I am able to use my present set up, then all the water will pretty much all get to operating temp at the same time. One way or the other, all the water in the cooling system will pretty much take about 15-20 minutes to reach full operating temp on a cold day, regardless of whether I use the 1.9 or the FI thermostat or the new fangled new one.
So, if I have clearance, via the use of the new throttle body, then I should be able to use my 1.9 + adapter set up. Then the only issue remaining would be finding a way to add a second temperature sensor for either the dash gauge or for the FI computer. On the 1.9 set up there is only one place for it. Could I do a splice of wires for both the dash gauge AND the FI to that one sensor or could I add a second sensor somewhere in the system? I'm sure I could do one or the other.
Everything depends on the clearance issue. I won't know that until my engine gets here and I can test fit things.......
The bypass ( See above would be to bypass the heater core via a 3 way valve ) and temps will stay stable.
Im getting them made, so you will ahve one, and if you decide against it, Ill take it back. Win/win
