The Magnus Motorsports dry sump kit comes with all the mounts, drive fittings, billet pan and oil tank parts you need to convert your 4B11 over to dry sump.
Here is our kit with the pump and belt installed.
With the dry sump system in place, the rest of the front end accessories were installed.
We had our valve cover powder coated for looks.
Here is our engine assembled and ready to drop in.
In our next segments of Project Time Attack Evo X, we will be installing the engine, adding and intake and exhaust manifold and Garrett turbo system. After doing the plumbing and wiring it will be time to dyno tune the engine. We think its going to make close to 700 whp with a wide powerband. What do you think?

interesting comment about the valve job. my experience has been the dimensions and operator are more important than the machinr.
Just some random advice: Manganese bronze needs bigger tolerances compaired to steel guides: They tend to pinch valvestems when warm. Ask me how I know….
A Newen is a CNC single point cutter that cuts in a continuous radius instead of steps. It can also be programmed to open up the seat and blend the seat into the bowls.
How did Toyota make the cylinders of the 2AR-FE’s block so damn strong and rigid? It greatly exceeds the typical limts Honda’s stock cylinders and it even goes pass this semi closed deck 4B11T.
If you are doing any kind of racing that last more than a 1/4 mile, like a 30 minute road racing session, that 4Piston cylinder head will not last long. Expect to find no more valve clearance. Their valve seat job is very poor.
They talk alot and do good marketing on social networks but when there is a real quality problem due to their work they don’t follow up and look for excuses.
We solved this issue by doing a new valve job with new seats and new valves.
This same issue happened on 4 distinct heads all from 4Piston. This same problem happened to a well known USA drag racing team…
And that is exactly what happend to us and we had to redo the valve job!
