Re: Finding true TDC on a 7AG

What OST is talking about doesn't even get around to the changes due to the block height. He is just saying that if you mix and match 7A and 4A timing pulley and oil pump the references will be wrong due to having different locations. How many people do this though? Do you have to mix and match thos...

Re: Petition to get replacement bearings for SC12 and SC14

OK then, so its going to be machining, either the case, the bearing, a sleeve or a combination of them. I am looking into that a little more right now. The first step will be to find the next closest bearing that meets all the required specs of the application. I will be talking to the NSK and Timk...

Re: Petition to get replacement bearings for SC12 and SC14

I have called almost every big bearing manufacturer as well as had several bearing distributors look into the matter. The bearings are 45mm OD and 46 mm OD. The two at 45mm are only available to OEMs. There are no similar bearings that come even close to working. At one point I was told I could get ...

Re: smallport to bigport swap

Re: Troubleshoot: 16V smallport not starting

Make sure there isn't any moisture in the spark plug wells. It's unlikely it would kill all four cyls but not impossible. To eliminate the dizzy you could see if there is spark coming directly off the coil wire. Are you bolting the coils on? They ground through their mount to the chassis. If you lea...

The really PITA bearings are 45 mm. The next common size up is 47mm. There is no way you could take that much material off the bearing.

I believe I can get you a BT oil pump. If so it would be about $180. Email me if you are interested and I will confirm price and availability.
If you are interested in the tensioner let me know. A part number would be great otherwise I can find it.

Are you sure you are talking about the 20Vs? The BT has 8.2mm on the intake stock.

Of course it is also entirely dependent on how fast you spin the motor.

Just one note. The GZE FW at least on the FR/MR trans is bigger than either NA FW. Something like 225mm. So the AE86 was all 200mm stock and can use the same disk and PP as the early AW11, is that correct? They can switch to a 212 FW, PP and disk same as the AW11 right? ACT does not offer any option...
