Ok i am still new to the site but not to working on my 93 teg. I have done a lot of bolt on parts. 4-2-1 Headers, cold air, light weight flywheel, stage 3 clutch, full lock diff. new rings, and pistons, seals, water pump ex.... Now that it runs good i want more RPM'S. I know that honda's bottom end is good for 9,000-10,000 RPM'S. i have to bet a civic Si. I have a PR4Y head. I will never go vtec What do I have to do???

My question is what parts are worth my time and money??? Where can i get the parts?? And is it realy worth the Extra 800 RPM's or so??? I read alot of people have used 403 crower, duel valve springs, new retaners, cam gears, 3 angel valve job. And so on. What do i get?? Need some help. I am a carpenter Not a tuner. But i want learn. Thanks for reading this.

first off dont take it to the 9000 rpm range without some bottom end work especially the rod bolts get arp rod bolts and u should be find but still would not recomend reving that high and if u want to beat that si without vtec insted of doing all that head work invest in some laugh gas only because the ls head flows like shit no matter how much head work u do it will still end up being like a stock vtec head and if u are going to waste the money on head work do it on a p75 it flows a little better but that is just my 2 cents ha ha ha ha ha

Ok sounds good. but what motor has a P75 head??? And will my PR4Y intake fit on it??? I think it is on a B18b1 maby.? thanks

To spin that 9000 rpm you will need ARP rod bolts block girdle GSR pan, pickup, and windage tray and you will need valve springs and retainers so you don't float the valves. Also you will need to get your ecu chipped to bump the rev limiter and gonna need a tune. Alot of money to spend on a PR4 head. Nitrous or turbo would be the way to go for you if your bottom end is in fairly good shape. But it shouldn't take much to beat a 2000 civic SI, b16's have no torque, they just spin good up top.

OK I have a moroso oil pan, block girdle, (The part that holds the top of the cyl's.) stock oil pickup , Arp Head bolts, and a remand pr4 head and a stock ECU that has a chip. good for 8300 RPM (but not in use at this time.)
It sounds like a nead a good pickup, ARP rod bolts, and the rest is all headwork springs and retainers, cams would be a maby!? But what i do know the b18a1 and b18b1 intake cams are the same, But the exhaust in the b18b1 is .020 IN bigger. Would this help??? sounds like a fun winter project.
Let it be know that i can not use spary, turbo or any thing like that. This is a stock class on a dirt track. I all ready am pushing the rules, just a little. turbo would be cool!
not only a civic si 5 speed bet me but, a cavalier and sun fire Automatics too WTF!! what a disgrace i am to honda/acura. If it was a nissan it would be all good 240's are fast. lol

But now i have a question. i have the oil light come on after it has been run hard, Like 5800-7200 rpm's for 6 or so miles. yes All 2end gear. What could that be??? The pickup, the oil return holes in the head or something eals??? I am running 5w-40 full syn.

thanks for the info P.S. B motor are great. and DD are nice too.

why u want to go 9000 rpm is your buisness but i very highly dout u are making any power differents than u doing 8300,8500 i haqve a ls/v without a block girdly or a block guard its a dd i take it to 8500 with no problems so im my opinion u dont need them but get a type r oil pick up pump if you bottem end is fine and u want to get more out of your ls get a good pnp a valve job better spring,retaners,valves throw a set of 404 cams in their with a gsr or b16 trans u will have a nice ls monster pushing about 170-175 hp with a lot of tourqe that shoul make u happy but that is just my 2 cents

no problem. i like info and thank you. 9000 would be nice but i will get 8300 with my chiped ECU. that is what i would like to get. it is a race car/ dirt track car. the more RPM"S i get the faster i can go in 2nd. that is right 2nd all the time at 7200 all race!!! i do not shift.
the type r pick up and oil pump is a good idea. but the question is how fun is vtec oil pump to put in is the question??? but the head i will go with stunk2 valve springs and retaners, p75 head and head gaskit. maby 403 cams. i was thinking of getting a taller 2nd gear out of a j1/s1, y21, y1 it is a 2.1. i have a 1.9 in my usdm ys1.
yeah it is fun now. but with 170hp or so would be cool. thanks for the info

most all the parts in a b series family are changable so there is no problem putting a type r oil pump/pick up in the b18b,a,c their all pretty much the same as far as the bottom end i mean dont get me wrong their are differentces like oil squirters and stuff but u will have no problem putting it in as far as your trans situation i dont tink u can change 2nd gear its on the same shaft as 1st unless i miss understand what u where talking about more info whould be needed like is it hydro stuff like that

I have read you can take all the internals out of a s80, and put it in a ys1 trans. My ys1 has a 1.9 2nd gear and the s80 has a 2.10 2nd gear. so that would give me more speed, in that gear. but will i have to change the final drive too. the ys1 is in usdm 1990-1993 int. and the s80 is in 1997 to 2001 type r.
what i mant about the oil pump, is where is it??

i dont know if u ever built an engine but the oil pump is what the crank shaft is sitting throw once u take the crank pully off there is like 6 bolts 4 on bottom 2 on top now i looking at it as if were on an engine stan upside down with the oil pan facing up it is what the oil pick up conects to

ok is sounds simple. that is some thing i will later this year. If i have other problems i know where to go. thank you for the help every one. i have a realy good idea of what i have to do.

With 403 cams you may be able to rev up there but it will not be making power that high. I would at least go with the 404's. They ARE streetable if you can deal with the idle. We've all heard how a cammed V8 sounds its no different in this application.
