Can a remap normally get any worthwhile increase in power from a normal aspirated engine without other mods?
IMHO ( and I accept people like cereal and Jim M might take another view) I went down the road of thinking that what I wanted to do was to get the engine taking the mixture in, using it and then putting out the exhaust gases as efficiently as possible, so I started with inlet manifold, air filter and filter flow and exhaust / silencer. I also looked at substituting the 4000 cell cat for a 200 but it cuases problems with the MOT emissions requirement
I then went on to look at remap, Tbs etc and concluded that I would be better off having my head, valves etc reworked to get the most efficient performance from what I had. ( try someone like Paul Dunnell or Raceline) I know there are outfits like Speclialise Engines who will tell you that you can keep the existing plenum, use an E 350 body and get an increase but I wasn't happy with the work I saw that they had done.
I didn't go over to TBs in the end becuase it would have meant having to engage with other things such as maximum delivery rev bands etc which I didn;t want on a road car
The Sport is, I think notorious for the f/d ratio.
So, my take- for what it's worth, is to recognise that what you have is a Ford 4 cylinder which isn't going to be great on mid range torque and needs working through the box. because to try and 'cure' this is. in the final analysis going to cost more than the final result is worth.
It's for that reason that if I can't rid myself of this desire for a more torquey, lazy motor that I may change my car. If I do, then it wont be a Morgan 'cos I'll succumb to my other love and go for an American Vee 8 ( prb Chev stock bloc)
