How is your VIS running in general? At the moment it's still sulking down at the Fiat specialist. in fairness it's not it's fault this time as the guy that runs it is ill, It's had three overheating issues in the last 18mths or so. This time it's the matrix. Normally it runs brilliantly, fairly low mileage, lots of new parts following major rebuild in 2019. I had the 16vt before and the VIS seems underwhelming, loads of torque, feels it could take another gear as revs so freely. I'm thinking a remap or a turbo maybe the way to go.

How well established is the 2.0-2.4 route? How many have been done, with what results? Is it a straightforward swop? Are you having over heating issues again?

Joe at FCSS has done a 2.4 conversion and remapped to about 200bhp without a turbo.
I think the engine is the same size other than being slightly taller to accommodate the slightly longer stroke. I think the bore diameters are the same. You make it sound so easy Toby It was wasn't it Joe? Just chuck it in, and job's a good un.... though you had to close the bonnet too, which took a bit longer I seem to remember you junked the VIS system, put more aggressive cams on too, plus lots of remap work. Anything else like bigger injectors? Anyway, the VIS in standard form is 155bhp (only 8bhp more than the standard 20v) and Stage 1 remap will make around 10 - 15 bhp more. I'd imagine that dropping in a 2.4 will probably cost a fair bit, just to gain the extra 15bhp over a standard VIS (the 2.4 is 170bhp with a bit extra torque) so I would think you'd be better getting a 20VT if you want a big increase in power. Especially, as the 20VT has uprated parts (suspension, clutch, gearbox, brakes) to deal with the power. I know what you mean about the VIS. It doesn't feel that rapid, but it is lots of fun and sounds great. I would like a turbo also, but the VIS is a good all rounder and pretty reliable. But I hope to get a 20VT one day.

Thanks Joe, the end result sounds good, any idea how much all this would cost? I'm imagining it's mostly time if the parts are available. Ironically I could end-up devaluing an original coop by modifying it! Give me a bell when you're free to chat. 01684 593187

What’s different to the 20v na and the 20v VIS, thinking of remapping my V.I.S I know it isn’t gonna be a lot but surely it will make a difference?
Is it worth it?……

Well... The VIS has the 'variable intake system' hence VIS which gives good low rpm torque and a bit extra in the top end. Also has a different ECU and a few other upgrades. Quite linear power delivery. I think it is more refined than the NA (having owned both). As for remap you'll get a max of 10% extra bhp at best. It does make a difference, but it probably won't wow you. Prices of remaps have gone up I think, so not sure if I'd bother these days. It depends how well your coupe is running at the moment. Sometimes a remap will help with flat spots etc. If you really want more power then you're better finding a turbo model. Or just enjoy thrashing the VIS... Like wot I does.
