You are correct. The TOGA pumps boast the "high volume" oil pump, but one has to ask, how much oil do you need flowing through this little engine? The stock nissan pumps are the ticket and they rarely fail. They are more than enough pressure and volume-wise and purchasing one will allow you to have some cha-ching leftover for something else.ks13 wrote:for whatever reason, that oil pump has seen poor reviews in this this here forum, by either boost boy or TMS. If the nico search engine worked, Id say do a search but because it is absolute garbage, perhaps others will chime in.
9000 rpm isn't good for anything. That short stroke is running away from the flame front in that neighborhood and your rod bolts are taking on the consistency of rubber. I don't know where this silly rumor that CAs like to be wound out like a gixxer came from, but it's BS. Make the power on boost not RPMs.tommey wrote:Accusump wont keep the pump from exploding..
No serius input on this subject?
9000 rpm on a stock pump is not a good idea. i have seen them blow before that.
Everyone here is correct. Why are you worrying about gears exploding on a CA pump? Where are you getting your data from? CA pumps don't explode, but your engine will and not because it was under lubricated, but poorly tuned. And this fictitious 9000rpm thing is crazy with the CA cult. What is this obsession of revving the oil clean out of the bearing journals? Keep knocking on the "Boost Gods" and you may not like what happens when the door finally opens. If you feel you must have your engine sitting in that RPM band, make sure you spend a bunch of money building correctly or you will fail tryingtommey wrote:Accusump wont keep the pump from exploding..

good point for sure .float_6969 wrote:And to make this a trifecta of CA18 experience speaking to you, I'll also tell you that that stock oil pump is fine, and you trying to take the CA18 to 9K is going to take A LOT of work, and A LOT of camshaft. And no offense, but if you were in the market of actually building a motor to run out to 9K rpm, you wouldn't be looking for a cheaper price on a "high volume" oil pump.
I will say that the CA18 @ 8K rpm w/the right cams and boost makes for a very fun engine. Give this thing boost, and don't worry about revving to the moon so much. If you do, you'll be glad you did. Trust us on this.
That it's over-priced and not much better than the stock pump. If you're cementing a CA block, then you don't need advice from anyone on this forum. Cementing a block is serious and you are obviously about to go all out with whatever racing you're getting into, so I urge you to try the TOGA pump and let us know how it functioned for you. Oh yeah, before you go boasting about what you got in your motor, I have a fully built motor with $900 rods in it as well as solid lifters just to name a few expensive goodies and see no need for a "TOGA" pump or a cemented block and I've been at this for a very long time. So with the amount of knowledge and experience between the three moderators and members with good experience on this forum, it's not good enough for those that are cementing blocks; especially that of a puny CA18DET (1200whp?) Good luck with whatever application you settle with.tommey wrote:I want to know what's s*** about it?
For all I know they can be calling it s*** because they didn't see any increase in oil pressure or something..
What's negative about the pump?
