sleepyhimiko Posted January 18, 2021 Share Posted January 18, 2021 Hey! My name is Ben, I own a 1999 MK4 Fiesta 1.3l and I'm interested in doing a 1.7 puma conversion! Any help or advice would be appreciated! 1 Quote Link to comment Share on other sites More sharing options...

I think it would be a fun project and a good chance for me to learn something new ☺️ Although the puma is a very lovely and fun car, I just really love the look and shape of Fords older hatchbacks and really want to get the same power as what you'd get in a puma 😅 1 Quote Link to comment Share on other sites More sharing options...
sleepyhimiko Posted January 21, 2021 Author Share Posted January 21, 2021 Tuning your mk6? How's that going?? Was looking into the capabilities of the 1.3 but it's really not worth tuning it apparently! Feels so sluggish as standard though, so maybe a little tune wouldn't hurt 🤔 Quote Link to comment Share on other sites More sharing options...
Chaz84 Posted January 22, 2021 Share Posted January 22, 2021 Nice mk4 the 1.6 ztech would fit in that 1 Quote Link to comment Share on other sites More sharing options...
sleepyhimiko Posted January 22, 2021 Author Share Posted January 22, 2021 19 hours ago, FiestaForever said: The mk6 1.25 has 75 hp so not so bad, I have a sports cat to put on and will in all likelihood get a cat back exhaust too. Have plans to stage 1 & 2 remap, possible cams upgrade and I have my eye on a small supercharger that will possibly increase power by 20% through the rev range. Have had the throttle body bored to a larger spec which has helped with performance. Also installed a malpassi rising rate fuel pressure regulator, and high power coil with magnacor sports ignition leads, ngk iridium plugs. It’s running pretty good already but it’s kind of a hobby to tune I had for some time now. Jheez man! it's sounding very nice so far! my mk4 only has 59 hp 😥 checked with a tuning company near me and if tuned, the 1.3 would only make an extra 8-10 hp so not much of an increase! even more reason for me to do a conversion lol. I've put a sportex backbox and race pipe on and really want to slap a 4-2-1 decat manifold on, done lowering springs (plans for coilovers to come) and started the zs bodykit (still trying to find a rear bumper and some skirts which are seeming hard to come by at the moment). I also fixed my idle issue last night! was well chuffed with myself! Quote Link to comment Share on other sites More sharing options...

sleepyhimiko Posted January 22, 2021 Author Share Posted January 22, 2021 1 hour ago, FiestaForever said: I think you could achieve a bit more than 8-10 extra bhp, but would cost some money to do. I think perhaps throwing a puma engine in would solve that issue in one go and then you would have the option to add more later. I think puma is around the 125bhp mark so that would be a considerable upgrade to the 59hp. I would be happy with just over 100 with mine to be fair but any more would be a bonus. Won't you have an issue with MOT test results with the decat system, thought it might not pass the exhaust fume test without a cat. What shape sportex exhaust do you have? I have been looking at their cat back systems, was interested in either the twin round back box or the boxta one. this is the sports cat/manifold I got here waiting to be fitted. That's what I was thinking and why I want to drop the puma engine in! The MOT would fail with the decat so I may see if I can get a cat back system sorted sometime! I don't have the MOT until November so there is time to do a few bits and source some parts! This is the exhaust system I have in at the moment! Just a single exit 3" backbox which I think looks quite smart on the old boy! it was the first modification I made to the fez and I'm very glad I did it! sounds way better than the standard system! I personally like the twin exit that you attached, would look very nice once it's on! I couldn't decide between a hoffmann system or a sportex at first! I've had a gander for a sports cat for my mk4 but can't find anything 😕 Quote Link to comment Share on other sites More sharing options...

sleepyhimiko Posted January 23, 2021 Author Share Posted January 23, 2021 15 hours ago, FiestaForever said: Exhaust looks nice brother, the sportex are good value for money. They have a deeper sound than oe exhaust. Shame you cannot find a specific exhaust for the mk4, I’m sure I saw a universal 200cpi sports cat pipe somewhere on the net. You would get a header or other manifold, and then have the universal sports cat in the middle section with that setup. Maybe something like this??

Chaz84 Posted January 23, 2021 Share Posted January 23, 2021 System like that made and fitted would be about 380/400 Quote Link to comment Share on other sites More sharing options...
sleepyhimiko Posted January 23, 2021 Author Share Posted January 23, 2021 7 hours ago, FiestaForever said: Yeah like that sort of thing, except I would go for a 200 cell high flow catalyst to pass mot, unless you feel like you want to swap it out every year or it will only be used on track. Ah gotcha! will look into that soon then! May just wait until I drop a puma engine in to do that though and make it worth getting. When are you planning on putting your sports cat on?
