According to Tomei;

Inlet 240° with 8.58 mm lift

Exhaust 236° with 8.28 mm lift

Do you know how to use the search button? You had better learn because I seriously doubt that you can think of a question that hasn't been asked and answered on this forum. Most of the questions you ask have been answered 1,000's of times.

:D cheers :(

You're crazy dude. Not much hope in completely understanding your questions but I think you're asking if you should keep the stock cams or upgrade?

Well depending on how much horsepower you're chasing and what your application is (turbine specifically).

I think the Tomei drop in replacement cams represent decent value for money for mild to high hp applications. Otherwise for higher HP applications JUN make drop in replacement cams which a few guys are running with giant horsepower numbers.

Stock cams are going to limit you making much more than 300kw at the wheels possibly less.

what you mean is:

"is it better to have the same lift and duration on both the inlet cam and exhaust cam"

the answer to that question is:

"maybe"

it depends on your goals for the car:

power

response

emissions

fuel economy

stable idle

turbo choice

tell us (or even better tell your tuner) how you stand on those issues, then they can recomend a cam choice for you.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
