![]() 1.7 L heads flow significantly better out of the box with the same valve sizes vs the 2L bus heads. ![]() #CARCRAFT VW FLYCUT DRIVER#It would probably be a better driver with the smaller 1.7L or 2L bus heads, and it might make 120HP now, with the bus heads not so sure. (is my daily commuter, has been for years now) ![]() I have a set of 96 flattops to slap in it if I ever pull it out for a little more displacement and CR. Web73, 2L manifolds, widened/tweaked Vanagon plenum to match (larger volume, match runner angles) and slightly stretched (for fan housing clearance) EMW HX replacement pipes with a 914 Bursch header for an effective tri-Y exhaust system. ![]() The web73-equipped 1800 in my squareback makes peak tq at ~3500 and pk power about 4600 RPM and pulls hard to almost 6K.hits pretty hard at 3500, the induction tuning really starts working there.īut: 2L Porsche heads (42x36, minimal ex port work, matching intake manifolds, 8.4:1 CR. It is also not likely to make 120HP with bus heads, even with ITBs, but it will make a nice driver. Microsquirt Is a nice simple/solid solution if waste spark and batch fuel is enough.Ī Web73 best matches your expressed desires, but depending on induction and exhaust may veer off the reservation some. #CARCRAFT VW FLYCUT FULL#Microsquirt will do what you want now, cheap, but it simply cannot become a MS3, it is what it is unless you are handy at SMD rework,Īnd even then it will just allow full sequential spark and fuel with mods. Pick up some LS2 coils, or a ~2000 VW Beetle/jetta "IGN4a" 4 tower for ~$35, waste spark, saves a couple I/Os. If not porting it/upgrading the valves forget the 163/86B, Web 86 or 86a and HD single springs are about the ideal setup.ĩ.5:1 static CR is too much for an 86, maybe 86a.Īs you aren't bumping displacement much, 9.5:1 will be hard to hit, a Web86 and ~8.6-9:1 is a valid combo.ĮDIS was a good solution ~10 years ago, but the world has moved on.ĭirect fire is far easier to troubleshoot if the need arises, and has been the recommended setup for years now.ĮDIS will work if you are in love with it for some reason, but no spark cut/soft rev limit etc. Web 86 for just a little hotter than stock, will still pull 6K+ with good HD singlesġ63/86B LC with dual springs if you are serious. What is the best cam that suits my setup? Money burning hole in my pocket and must make my move soon. Just an smooth engine for weekends and highway cruising. Due to limited supply here in Europe my choice is narrowed to Webcams - I can buy cam and lifters from CSP. My experience with aircooled engines is quite limited and selection of camshaft bothers me just from the begging of my project. ![]() One of the biggest questions for me is the camshaft.
