I'm running mine with in the "hang" style with no snubber and no bottom mount but tried a few variations before that. The mount transfers noise for sure but the best configuration was OEM rubber mount below with the snubber up top. I kept an air gap between the snubber and the diff though so that it only came into play during hard acceleration. One other thing to note. If there is any other issue in your drive train the mount will telegraph and amplify it. Derek

I own a Sunnen line bore machine and I would be trying different sets of towers before I went that route. Setting up the boring bar to bore the correct ID and getting the head true to the machine is a major PIA.

So many questions:) Durability and reliability are directly connected to HP, torque, tire width, driving style etc etc. Turbo car with wide tires and a propensity for hole shots....You are going to have a bad day. Under 275 to the wheels and the occasional hole shot when your brother in-law comes to visit....Probably going to be fine. Here is the first non functional prototype. I took one of my extra CD009 prototype castings and sliced and diced it to see if the conversion was feasible. This is the final-ish shifter design. It uses the stock BRZ shifter. There are aftermarket short throw shifters available. Costs are going to be in line with the CD009 conversion. The bell housing will be right around $1000.00. The shifter mount should come in under 250.00. For the total package you will need a TL70 new or used, bell housing, shifter, new yet to be designed cross member and most likely a driveshaft. Used transmissions are around 250.00 - 500.00. New ones are available for 2300.00 or so. Rebuild parts are Reilly available as well as aftermarket gear sets. Also there is no provision for a speedo cable so you either need to use a GPS speedo or Speedhut makes a motorized conversion that takes GPS data and converts it to a motor drive. The biggest reason for this conversion is for you to help fund my retirement but beyond that you don't need to modify your sheet metal so returning to stock is easy. Second would be bragging rights. "yes but mine has 6" Seriously though, rebuild parts are drying up for the 240sx transmissions and that is what originally got me started on the CD009 conversion. I wanted a new transmission in my car and both the CD009 and the TL70 are available new at what I think is a reasonable price. I'm waiting of the first two castings to arrive from the foundry so I can finalize things. They are poured I'm just waiting on them to heat treat. I'm keeping a list of people interested so if anyone is, email me at kick@datsunworks.com with the subject: TL70 6 speed. Derek

Not trying to plug my product but I'm working on a conversion bell housing for the Aisin TL70. The TL70 is a six speed out of the BRZ and FRS cars. The swap does not require cutting the car like my CD009 conversion does. I've had the CD009 in my car for a bit and I can say with certainty that a 6 speed with 1:1 5th matches my style of driving. Fast off the line and the overdrive in 6th helps a ton on the highway. I'm running a 3.54 rear. Here are the TL70 ratios. You may want to plug then into your calculator. The TL70 is cheap and plentiful since young drivers have a habit of wadding them up:) TL70 Gear Ratios 1st 3.626 2nd 2.188 3rd 1.541 4th 1.213 5th 1.0 6th 0.767

I'm running a Rostra 250-1223 with a Rostra 250-3592 Dash Mount Cruise Control Switch and a 250-4165 Magnetic VSS Speed Pulse Generator. It works pretty well. It's a little finicky about engaging but other than that it's been fine for probably 15 years.

+1 for Timesert. I use both coil inserts and timeserts. They both have their place. Lots of aluminum parts require coil inserts especially in aircraft work.

Any bearing (bushing) that is pressed in would probably need to be reamed or honed FYI.

Well we are now talking visceral vs physics which is a different discussion. A quicker ratio will require more input torque. That I believe isn't open for discussion but I will certainly listen. That was a joke. If I was in the UK I would want a RHD. I'm in agreement as to the slow side. I installed comp steering arms 20 years ago and have never regretted it. Agreed. It's a fair outlay of capital I'm sure. The only reason I've commented is the question about the input torque being higher and Jason's non answer. It will require more input torque. It will have a faster (better) response. Coupled with the new power steering low speed assists would make a great combination in my opinion.

But doesn't the ratio effect the input torque required to turn it? I know in every other application gear ratios and torque required go hand in hand. Probably had to do with the steering wheel being on the wrong side of the car in the UK. With the stock width tires on the S30 input torque on the steering wheel is manageable but since most people that own these cars have increased the tire sizes, input torque becomes a valid issue. That is why you see kits available for power steering available now.

Letterman has you covered.

I'm not sure that is a fair statement regarding Biden. He really hasn't been a leader in an executive branch nor was he ever a governor or mayor. He chaired two Senate committees but I'm not sure if that is really considered a leader. He was Vise President though and has most certainly been in the same room when decisions were made.

It's a lack of leadership that has put the US in the position it is in. A good leader sets the example and sets the narrative. Nations across the globe are under attack. How the leaders responded dictated the outcome. It's like we were attacked by a foreign enemy and the answer from the federal government was for states to buy their own bullets on ebay. Not in a pandemic. In a pandemic your actions control MY destiny as well as yours. I'm fine if you want to jump off a cliff. If you try and grab me as you go off the edge I'm going to have something to say about it.

Vaccine for Covid or selfish stupidity?

North of Mount Dora up to Ocala can be pretty decent. There are so many little lakes that the roads have to do a lot of meandering and that can be nice. Between Ocala and Gainesville west of 75 has some decent runs. Since we have no mountains, lakes and swampland dictate the path the roads take.

And you are correct. Just happen to have my car up on the lift and rotating would probably make it worse.

+1 for Flipping the rear vent tube. This would make replacement of that hose a lot easier. Great job though and the price seems very reasonable to me.

So the brackets that came with it don't line up with the holes in the evap? Most of us here have gone the Gen 2 mini route so you are kind of a pioneer. From the angle of the pictures it looks too large to fit under the dash. Have you test fit it yet? You are going to have to fab up some custom brackets no matter what.

The Jamb nut would need to be tighter than the locked up motor and that could be tough.

Now you all know I love to machine stuff but it occurs to me maybe taking an old crank gear and grinding flats on it would be an easier way to go.

Hi everyone. Here is a link to the FAQ on the head. http://www.datsunworks.com/Blog/faq-for-twin-cam-cylinder-head/ The blog has most of the posts from Hybrid Z without all the discussion in between. I'm in production as we speak on 4 non-VTC heads and one VCT prototype head that is for me. The head is based on the Honda K20 and uses all K20 valve train for the exception of the cams and the timing chain. The S7 tool steel cam cores are produced by me and then after heat treating are sent to Schneider Cams for semi finishing. They can also grind the lobe profile as well or you can send it off to another grinder. Semi finishing is basically grinding all of the bearing surfaces to spec. The pricing being thrown around are based on what I think it's going to eventually take to produce the heads. Keep in mind there is no "economy of scale" on these. It is and will always be a very small market. The price will never go down. I'm happy to answer any questions but the FAQ has most of the pertinent info. Thanks Derek

All good considering. Just got the power back on at the house Friday. No damage to the shop or the foundry so hopefully I'll be back on the heads asap. Thanks Derek

Someday we will have replicators but that time is not now. It's a good thing that people get excited about this technology but it's a better thing that they are realistic about what the end product will be. Then time isn't wasted trying to make something that is destine to fail. I think OP should produce the electrical plug mentioned earlier. This will be an excellent item to test the limits of both the human and machine. The overwhelming descriptions on 3D printers is "for visualizing and prototyping" not production. Recreating an injection molded electrical plug will give everyone an idea of what to expect and what can be done. In my opinion the cross sections are way too thin for printing but this tech changes by the minute so I could be wrong. Not trying to be a downer just trying to steer this in a practical direction:) Derek.

3D scans without a ton of refinement are best suited for organic type items. Any item that needs to meet size criteria like an electrical plug is probably not a good choice. Traditional reverse engineering techniques would be better suited. The only time I go from scan to part is when it is something like an ornamental leaf or a reproduction part that needs to have all the detail and mistakes. With a scan you are working with meshes. Even though printed parts are from meshes they are generally a solid model that has been meshed as the final step. Scanning is very handy for reverse engineering though. I'll often scan something and import it into my solids modeling program. I then start building a solid model around the mesh. In my opinion the foam that dashes use is ill suited for CNC machining. Too soft. You would want to scan the dash, create a solid model. Use that model to make an injection mold for the foam. Nice equipment for sure but if you can't solid model and CAM then they are paperweights. It is great to see that they are making the investment in this kind of stuff. The best advice I always give is learn to solid model. Fusion 360 is free and powerful. They probably have post processors for all that equipment. The list of equipment sounds like Tony Starks workshop:) Derek

The problem for me here is I can't edit any of my posts. On HybridZ I was able to go back and update all of my posts. It kind of sucks because I have a couple of "how to" posts here that I would like to update.

I have not used Peninsula but have had them quote a few things for me. They seemed to know what they are doing. I use Certified Metal Finishing in Pompano. Not sure if they do the process you want but they do a lot of stuff. I trust them to impregnate my head castings so that should tell you something:) Unless you plan on driving your parts there what difference does location make? Derek
