Was thinking about doing a little rebuild to a old school 1st gen b16a I just recently acquired for my crx, I had a b20 the tq was nice but its less of a reliable motor & I'd rather have ability to rev 8k in Vtec then have power fall on my face at 6k or whatever it is. Thinking about taking it to my machinist and having it freshened up.

Here's what I'm planning

1988 JDM b16a (OG af)
81.50/82mm CTR rs machines pistons
Shotpeen & recondition the connecting rods
ARP rod bolts
ACL race bearings
OEM Honda P73 oil pump
OEM Honda 22t Water Pump
Cometic headgasket 2 layer?
ARP head studs
Oem gaskets all around
PLM rmf style header
P73 ITR intake manifold
InlinePro 68mm Throttle body/Thermal TB gasket
Hondata Intake Manifold Gasket
PasswordJdm Kevlar power chamber
Skunk2 tuner2/skunk2 cam gears
Supertech Dual Valve springs & Flat face valves

Can I run 91 still? Should I is run stock valves, will I need injectors, should I just run ctr cams? Will I run into p2v issues with tuner 2 I originally just wanted to do a p30 set up but can't find any. Will I have to run a oem 3 layer, gonna tune on Hondata s200 p28/p30
Car is just gonna be a cool lil daily project I'm gonna eventually resale I got the motor & si she'll cheap so it's kinda an investment. Lmk what's the best route in your opinion I don't wanna hear any b16 haters cause honestly I can care less I have a sleeved 85x89 this motor isny about making 200hp in a b16 if I get there cool but honestly ill be happy with anything I just don't wanna be relying on a 24 year old motor that could be on a stock headgasket for all I know

 

Why dont you just do the B20 like your doing the B16?

but hey, dont listen to me.. throw all your cash into the B16 build. Then afterwards, when a b20 walks you on the street, dont start crying. Oh wait.. you dont want to hear any B16 haters..LOL

 

B20/vtec can be reliable, just pay close attention to detonation is all.

I'd say you have it figured out man! Do the PCT's over the P30's, you won't have any clearance issues and the S2S2's will respond well to that compression. My roomate built an ls/vtec using a 1st gen B16 head, he replaced everything BUT the valves and one of them dropped with only 700 miles on the rebuild. He was using Pro1 cams and we came to the conclusion that the valves simply had too many miles on them for an aggressive cam...so I would replace them. The only other thing I would suggest is doing a different intake. A cheap 3" short ram off eBay and then buy a velocity stack with filter and you're set. The injector thing is weird. People say everywhere that stock injectors will support 200+ hp, but I maxed mine out at 170. So if you have a few extra bucks, the Acura RDX injectors would be great for you. Engine management could be much better but hey, if you have it layin around...might as well use it. Let us know how it does

 

I have a sleeved 85x89 that's in finishing stages I could finish it
But I have bigger ideas that I need to sit bak & save on to accomplish.
I just got this b16a to drop in a 91 crx si shell I picked. I settled on just getting CTR cams & I already have the IM/TB/header. I just know the motors from 1988 and probably has a good amount of miles on it. I don't mind spending a couple hundred to get it freshened up.
I was tryna see If I could find a healthy b18c block but no luck. Really not worried if I get walked on by a b20v. I just want my lil poor mans ctr set up lol.
I'm trying to work with what I have and I'm not trying to start a whole 2nd build for a car that is intended to get me to work and back. I wanna have some fun with it but I don't plan on starting another $3k+ build. I just want fresh pistons/bearings/pumps & a mild car. I just wanna get an efficient tune & whatever I make ill be happy with. I wish I could find 81mm p30's new though...

 

Thanks for the chime in clean rice, I found some 01 ctr cams on new Buddyclub cam gears for $300 I'm gonna pick up today so I'm kinda throwing the tuner2 idea out the window but yeah I just wanna be able to get this running clean whatever cheapest/reliable way possible. :/ poor power chamber intake looks so good yet no numbers to back it up. Ill check out those rdx injectors how hard is it to eliminate my resistor box? I have quite a bit of wiring to do.

 

In short it went like this
Crx shell-$1k
B16a swap w/ j1 cable trans $400
Ctr Pistons-$200
Arp rod bolts-$75
ACL bearings-$130
Machine work/assembly-$250
Tune-$200
Ecu/Hondata-$200


I'm pretty sure ill see my money back when I resale the car & be able to enjoy the fruits of my labor.

 

Honestly with those pistons I would use RDX injectors its not just about flow its about spray pattern and PCT pistons work well with better injectors.

 

Dang didn't know that makes sense tho I know its not the best burning piston but it makes sense a good atomizing injector would make things work well, I pulled my intake manifold looks like someone tried porting it, it's not to bad just the valve guides are grinded flush should I be worried?

 

Run 60psi fuel pressure and there even better,and if you can ditch the P73 manifold and run a cut open and ported P30 with a 68mm TB its one of the best intake combo's I have ever used on a B16a

 

I am making 161whp on a fully stock fuel system from pump to injectors and I have room to spare with my injectors.
OP your plan is great the only change I would make is the choice of block. Go with the B20 block over the tiny B16. Trust me on this you will love the B20 Vtec and you will be disappointed in the B16 after all is said and done. I have yet to run against a B16 that has been able to pull on me, I run a mild Ls Vtec.

 

Once again this isn't about peak numbers. I'm gonna work with what I have. I already have a 85x89 sleeved lsvtec planning on making 250hp 160tq I'm not trying to do a full b16 build. I already came down on what I'm gonna do I'm not even gonna bore I'm just gonna rehone & drop 81mm rs machines ctr slugs. I already picked up CTR cams last night for 280 w/ Bnib Buddyclub cam gears. I'm just gonna
