Mechanic is having trouble with the different height valve springs. If going solid eliminates the Vct does that mean I can use same height valve springs on each side?

Have Tomei Solid 272 cams 9.25 lift as well as the Tomei lifters, What springs would I need to make this work with my current parts and will I need anthing else?

Im a bit conused by this. Why not by a NEO RB25 head?

There are definetly ways to keep VCT and go solid. Im just a little confused as to what the problem is and why he cant find some valve springs that will work

because the springs are different lengths on each side and the cams run big clearance he says he is having trouble figuring out what springs I need and how to make it work with what I have. He has suggested to me buying a whole supertech kit, but the supetech kit has same size valve springs on each side, and he keeps telling me I need different sizes on each side to make my parts work so I am also really confused and not too great with this stuff

Your not the first person to do this. Im sure its not as hard as he is making out. I would take above advice

He is contradicting himself and in my opinion whenever someone is doing that, they arent real sure what they are doing

Managed to talk to someone from crow cams that happened to be there who said he did a conversion not too long ago. Said because the springs are different size you need two different springs that aren't even listen as rb25 springs and said he would get the part numbers for me. He also suggested buying a washer seat on the exhaust side to  make it the right height.

      Much less twat-tastic. CF wheels are too garish for civilised use.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
