Hi guys..
I´ve got a sleeved b20 bottom end and the stock b20 oil pump. I want to build up a high rev FI motor (aprox. 10500 rpm) so I need a new oil pump. Now I´m thinking about to buy the prodrive oil pump gear. But I don´t know if it fits to the b20 pump cause there are often difference in the bottom end parts between the b18c ,b16 and b20 engines.
What do you recommend?

 

Just get an OEM type R oil pump...you'll be set.
Dont know how safe it'll be revving a b20 to 10,500 either. Why so high?

 

its a fully build bottom end with darton sleeves, 84mm je pistons, pauter rods, cometic gasket full ferrera valve train crower turbo cams.... and I want to get the most power out of the engine..
Do you know if the prodrive ear fits into the stock b20 pump?

 

That i'm not sure, but even though its a build bottom end it doesnt make the rod/stroke ratio any better. Think about what the stock redline on a b20 is? maybe 6500-6800 right? Now u wanna go from 6500 to 10500? thats pretty nuts. I can see like 8500 but i feel 10,500 on that is not to smart. Most turbo guys only rev to 9500. Just some food for thought.

 

ur gonna lose power at 10500. ur cams arent gonna make power way out there.

ud be better off at 8500-9000.

make more power and keep all that dirty oil off the track and in ur bottom end.

 

Why does the crower turbo cams only make power up to 9k... I thought the make power up to 10500.. Duc from the ground zero guys makes power up to 10500 with stoc GSR cams...

 

Sorry I forgot.. duc has a b18C engine so the stroke is lower than mine.. Ok maybe 10500 is a bit to high but when I go with 9k or 9500 Whats about the oil pump.. So ITR is a good way but I already have a oil pump why don´t upgrade it? I don´t know the retail for a new OEM ITR oil pump but I think it will not be less than the prodrive gear. Please tell me when I´m wrong.

 

Do you have the entire rotating assembly balanced and blueprinted?
If not, I wouldnt think of taking it more than maype 500-1000rpms over the stock redline.

 

Use an ITR oil pump and a new ITR crank pulley.
If you are really concerned use the ATI damper pulley. Crank vibrations break oil pumps.

Trust me your better off getting an ITR oil pump... $108 http://www.inlinefour.com/intypoilpum.html

VS.


Pro drive oil pump gear..$295

So do about a 8500-9k redline with an ITR oil pump...you'll be straight

 

yea.. thats a great side thanx man!!! But whats about all the belts if I´ll take a ITR crank pulley.. Do I need a ITR timing belt then?

another dreamer here? are you listing your dream engine? cause i really doubt you put that motor together if you dont know anything about a crank pulley

 

I´m not a dreamer man.. I have the stock B20 crank pulley and I know that there are differences between the pulleys. I´ve never had the oportunity to compare the pulleys so thats the reason why Í ask you guys about it. Sorry for the question but I thought somebody have a better answer than you!!!

 

Go with the factory honda pump...supposed to be the best. Unless you want to go external wet or dry sump. Isn't the ITR pump the same as the GSR/Si?

 

What rod length and stroke are you running?
