1984 TVR 280i in USA
Discussion
I have a TVR 280i sold new in USA (I was told). If I'm reading the chassis number correctly the car was made in Feb 1984. I have a rebuilt long block cologne v6 that was not the original engine according to the chassis no. All ancillary parts, plenum, fuel distributor, injectors, etc. were not on the engine when received it, so I'm assembling all parts. Can anyone answer these questions:
1. Would the original engine for that build date have the lambda sensor and lambda valve (oxygen sensor and on/off switch). The fuel distributor has the lambda valve (don't know where oxygen sensor is or should be). My underlying question is whether the ECU for this build date will be looking for the lambda sensor, or it there another module that handles this function.
2. At what degree Fahrenheit should the thermostat open. There are several that fit. Also the parts diagram I'm using shows a spacer in the thermostat housing. Where can I find a spacer and does it go in front or behind the thermostat.
3. The oil cooler sandwich that goes between the block and oil filter needs a seal between it's self and the block. Where can I find this seal. I don't want to buy a new sandwich if possible.

Thanks for responding. I’ve read a lot on the Bosch K jetronic fuel injection system. A few questions if u don’t mind.
Is your manual specific to the K Jetronic in your car?
Do u know if yours has the lambda sensor and valve?
Does your pressure control regulator have an outlet for atmospheric and is it connected to the air box?
Since I didn’t take it apart and don’t have all the hoses I’m trying to figure where things hook up by what the part does. I would love to find car specific manual, if there is one.

Some things/info that may help.....but from a long time European Cologne V6 fiddler (kits as well as TVR), not US.
As far as I know, there were never any spacers for the thermostat, the thermostat is effectively clamped between a front 'large hose' outlet, and a rear 'bypass' outlet.
The thermostats were 82C or 88C , and make sure you get one with a 'block plate' at the back, which blocks the bypass hose at the rear of the thermostat housing.
(yes this is a bit weird, I think it's because Ford put the thermostat at the bottom, so it won't warm/open without some flow past it). See somewhere like Burton Tuning on web for pictures.
Injection.
Most wedges in Europe had the early no feedback K-jet, which has only a warm-up regulator and an extra crank-start injector. It has a 'cone' (where the flap is) with 3 distinct zones (as there's no feedback, mixture was tuned via change in cone angle...). I don't know what TVR did to get it US approved.
What I DO know is that later K-jet went to electronic with an EGO sensor and a 'mini' control unit, and that these have a straight single cone, with an extra valve on the side of the 'banjo' outlet (where the 6 fuel outlets are), and from what I read (a while ago), these are almost universal, so may well be able to use one from an Audi or something.
The K-jets were used a LOT by VW/Audi and Mercedes (and even Ferrari !) , so if you know of friendly VW dealer, they may be able to help with info...
I do remember seeing one of the 5 cylinder Audis with what looked like an almost identical 6 outlet unit and flap size (but electronic) which would possibly work fine on a cologne.
Hope that's useful...
