So on a previous post about my turbo gsr build I had a guy advise me on not using the acl race oil pump but I had already ordered one. When I received it in the mail I took it out to inspect. My first reaction was not good the gears seem to have a awful amount of play, enough to where I can put my fingers on the inside of the hole and move it left and right quickly and hear clacking and what feels like a gap between teeth. My oem pump with 220k miles is still smooth with no play. I spoke to the seller and he swears they are supposed to be like that. Says he builds Honda’s for a living and uses one on his,but I have talked to other builders and machinist that say there is no way they would use it. Has anyone else ran into this before?

 

Stick with OEM. Even Melling is hit or miss..

 

For all my builds I call up Acura and order a brand new one, put it on just the way it is and it supports plenty of power.

 

im going to go oem now just wondering if anyone else has ran into this with acl pumps before

 

What’s with the increase in Oem oil pump price though :/
I use to see it on eBay for $130-140 shipped
now it’s 200 area :/ so sad
Worst part is I definitely bought one bnib left in garage/room > like 2 years ago and now I come to finish my build missing!
Sucks but still Oem!

 

I was told Honda is slowly weeding out all these, what I thought were, common B series maintenance parts. Prices are more than likely going up due to supply decreasing. I believe I just paid around $150 for a ITR one earlier this year.

 

^This. Eventually only aftermarket or remanufactured units will be available.

 

Stick with the OEM pump. Stock up in case they get disco'd.

 

Hi, I would “ONLY” use the original oil pump that comes with your vehicle & buy with it the Toda racing oil pump gear 84mm 15131-B16-000, & the Toda racing timing belt 06141-B16-000.
I installed these two parts back in 2005 & are still working strong. I was heavily involved in motor racing for 24 years & not once did I have an issue using these Toda parts in my B16a
Make sure you find a technically minded engineer to build your engine properly.
