Default OS 12TZ 5 Port

Hi,
I'm about to buy a OS 12TZ 5 Port engine for my V one S - and was wondering if anyone can tell me if there are hardships about using this engine with the car? (Mounting, Crank size issues. etc. )

Thanks.

I own one... it is hard to break in. Use a hairdryer on the engine when you try and start it up. The engine is very tight and will be hard to get started for the first couple of times. Other than that, follow the breakin procedure with your instructions and you should be set to go -

As for the car, I don't think there should be any issues... check with the manufacturer if you think there is a problem.

well, i have been doing about 6 mins and 30 seconds to about 7 mins of run time with the ostz 5ports engine. i'm also using an outlaw 6mm pipe the engine has been very kind to me and didn't give me any problems except for the break-in procedure in which it's very hard to get the engine started wihtout using a blowdryer to preheat it. it's very tight at the top dead center.. other than the that, the engine is great right now i'm using an osspeed tz 3ports and still in the last few tanks of break-in. hpefully the engine will out perform the ostz 5ports

How far should we tighten this portion?

start with the kit settings and adjust from that point how you like it best in you're track conditions.
mugen setting is .8mm from top of top of clutch nut to spring nut.
kyosho settings should be near that

As i do not hav much time to go dw to the tracks to get help and i'm still doing my run in, i discover that the engagement is abit slow and i hav to throttle higher rpm just to engage the clutch. hence i would like to find out some setting from the rest of the os engine user

you should make sure to shim the bellhousing first so that it has just enough clearence to spin freely without touching the clutch shoe( between flywheel nut and part 178)
keep adding a shim and till it stops rubbing on the clutch shoe and keep checking each time you add a shim by refitting bearings and clutchbell back on and checking how it spins with clutch facing up.
once you have that set, fit parts 178 to 143, part 146 and 147 are the .1mm,.3mm shims that come with the clutch.
then measure how much end play there is and shim it till you have around .5mm end play and that should be about right

well, it depends on the type of track you are running. i guess you could start at about 0.8mm. from there, you could either loosen or tighten it. as for me, i'm at about 0.5mm since our track is technical and only has fair traction. i just bought the clutch spring (H) that's on the upgrade parts list on manual. it's bronze in color. it's just as hard as the black spring but with lesser coils. will let you know how it performs by the way, i'm running an osspeed tz 3p
