so little update for you.
After taking the Laguna on a 200 mile round trip to hand over my M3 on the weekend I can confirm its engine is totally gutless.
Luckily as I mentioned before I do have a 182 lying around so that is now the donor car for this project.
After a chat with both fulcrum and ARC in regards to a cage the Laguna is booked in with ARC for the start of April. The decision to use ARC was totally down to timescale, I'm a little impatient and really want this project to be cracking on at a decent rate. Cage wise I will update with the final plans when i have them but its going to be a pretty close replica to the super touring cage.
In the mean time I will be pulling the old engine out and seeing how the F4R fits and what will need doing to accommodate that. Further plans for the engine are a set of cams and ITB,s as well as sending the box away for some final drive work and a diff.
currently using my old PH1 engine for inspo! wish id never sold that little car!
