k04 hybrid machining/clearence tolorences info/help, fuel pressures & water meth?
Hello folks, great forum you have here with some great info on offer!! Im after a little info that i cant seem to find to help finish building my k04 hybrid up for my engine build, im using the rs6 2018 turbine and 2283 comp wheel, im gonna port and flow the hotside inlet to 45mm and the wastegate to 28/30mm (same as bill did to wellys) and use the bigger k03s penny, from what i've gleaned so far from various threads, the comp housing inlet is gonna be machined out to 45.5mm?? and the hot side is gonna be machined so that it has a 0.3mm clearence around the turbine wheel which is unclipped??, im not sure if these specs are correct/optimum so any input would be greatly appreciated? also i was thinking of using the forge k04 adjustable actuator? what do people think/would you change?
the spec of the engine/car so far are as follows, was origionaly bam with egt sensor in turbo:-
agu block & pistons with I.E rods, new oil pump & pick up, gaskets & seals etc,
AEB head with standard bam vvti sedtup, cometic head gasket & ARP stud & nut kit,
relentlesss v3 manifold with 45mm ported collector and port matched to cylinder head (copper plate gaskets),
AGU inlet with 10mm phonelic heat spacer,
gennesis 550's & 4bar reg or may use fsi adjustable unit (3-5bar) with pressure gauge? views/input on this would be welcomed?
wallbro 225lph intank pump and bosch 044 external with hi flow check valve & ibiza cupra filter,
welly cooler & 2.5" alloy pipe work through out & alloy map sensor pipe,
low temp 82 degree thermostat and fan switch,
pinned/dowled crank pulley and kevlar belt,
relentless 3" down pipe & de-cat with non resonated 2.75" full miltek,
badger 5 3" tip with 3" CAI down to filter located in lower bumper corner,
good quality silicone hoses through out,forge 007p with blue spring relocated next to TB,
spec-r catch can, n249 delete,
1 range cooler ngk iridium plugs gapped to 0.7mm, ball & spring mbc to cap boost if necessary,
AEM wide band and boost gauge in car,
And i think thats about it? The only things im not sure about are the machining sizes/tolorences to be done to the hot and cold side housings? the best actuator to use? should i use the 4bar, 3bar or the FSI adjustable fuel pressure regulator? and am i gonna need water meth?
This was origionaly going to go into my LCR but i've just bought an s3 to put it all in and am gonna put the s3's bam engine back into the leon for the missis!!
when i've got it all back together im thinking take it to bill@badger5 or niki@r-tech for the mapping?? any help, ideas,info or comments would be welcomed??? cheers in advance,Rob....
p.s. great forum...
