you need to get rid of the stock fuel pump that only puts out 195 and get one that puts out 255 then bord it out to a 2.0 get flat top pistons, titanium sleeves and rings. do that you looking at a big jump in hp because of what's done already. after that take it to a performance shop and have them upgrade you computer to dump a shit load of fuel. that should easily give you 75-100 extra hp

$2500 could buy you a B16A motor swap my friend....
Unless u just wanna see what u can do w/ your SOHC...in which case I recommend a blueprint/balance, some higher-compression DOMED pistons, and stronger/lighter connecting rods.... I'm assuming you want to go All-Motor because of your headwork.... Also...a little bit of ECU tuning (A'PEXi V-AFC is pretty useful) But not to add fuel. hondabitch - please....research. Just adding more fuel will not give you "75-100 horsepower". If you end up added too much you will run rich - that's NOT a good thing.

I agree with Vtec_Boi here. Dumping fuel into an engine will just make it run rich. The whole purpose and theory behind HP is getting as much fuel into the engine WITH AIR. Its perfect when you can get alot of an AIR/fuel mixture into that engine. Thats the purose of porting and polishing and what not. To get as much of that good stuff into the combustion chamber. Personally I would have gotten a B16a... Not like I don't already have one =) but you would have been better off with the DOHC Vtec. The built SOHC won't ever have as much power potential as a built DOHC.

Is swap fever catching again? The guy has a SOHC, he has done alot of work to it, and thats what he is working with, bottomline. Sure he could always get a B16, or aB18 or an H22, or he could just buy a car with a V8! The point is, there is always a bigger engine out there, if the guy wants to get the best out of what he has, I say more power to him....I just wish I could be of more help and provide him with some info! Off the top of my head, I could think of new rods and pistons to up the compression ratio. So, is anyone up to the task of helping? Obviously, getting alot out of a SOHC is going to be a challenge, but when all is said and done, you can be proud of the work youve done. Isn't that why we do this stuff? (I know thats a big part of it for me.)

I am going to be sticking with the SOHC and the plan is to get 250HP to the wheels with the SOHC. It can be done and it will be done. I have seen N/A SOHC's run 12's I am going to be going F/I

The SOHC's are underrated in my opinion. In a way thats ok... Its fun to be different and smoke the Dual cams.
I have been SOHC ever since but I also build some dope Dual cams. So what do you want out of the SOHC? Do you want to run 13s, 12s or even 11's All Motor. Ok, lets build a motor for the general public. Taking into consideration, costs and reliability. With this in mind, I would shoot for a daily driven 13 sec SOHC VTEC or 13 sec non-VTEC SOHC. When I build a setup like this for people, I start of with the headwork, cam, and if the cam needs it, performance valve train. Polish the intake manifold and match port to the head and with the ported throttle body. Get the Basic I/H/E. This setup will get you into the low 14s and is very reliable. Now to get deep into the 13's. Lets do the bottom end. Since it wont be pushing HP near 200HP. The block can retain the stock rods. The only upgrade will be the pistons. An 11:1 to 11.5:1 compression piston would be good on the street on 91 octane(we have a b20/VTEC on 12:1 on 91 octane, runs fine... 1+ yrs already). With this block and head setup, a little tuning with the cam and cam gear can take the SOHC VTEC or the Non vtec into the 13 sec range. Not bad for a daily driven SOHC. Of course if you want to get faster, higher compression, overbore, more aggresive cam are all options for more speed. I have been racing by 89 CRX SOHC nonvtec for 3 years. Its very consistent and is great for bracket racing. The setup is just headwork, cam, cam gear, I/H/E. and on the stock clutch and stock block. Been running 13.6's @99mph for 3 years and with 60k+ miles on the motor. SO give the SOHC a chance... not everyone can do a swap, and its not necesarilly the answer to more speed. A dual cam/hydro swap into a CRX can cost at least $3000. Regular stock dual cam swaps usually only run in the mid 14's. you'll spend less on the the SOHC buildup and be way faster that them. Well... hope I can be of more help. Feel free to email for any questions. Wil www.exospeed.com |

That was an awesome post. DO you know anything about F/I on a SOHC. That what I plan on doing myself. What do you guys think? I am going to be running a Greddy Turbo and also going to be doing a build-up. I am going to be sticking with the smaller turbo because it will spool up faster and I am going to be running prob 8pounds.

Since you've already done the headwork, might I suggest a JG Pro Series short block assy ($2295 w/ core exchange). Hot tanked & jet washed (to remove the sludge from the oil galleys), stock cylinder sleeves are removed in favor of thicker wall ductile iron sleeves. Then the whole thing is balanced, blueprinted, and assembled with ESP rods and SRP pistons (your choice of rings) w/ compression ratio's from 8.5:1 - 11:1. These shortblocks can handle up to 30psi of boost and are rated for a maximum output of 450hp, with the nescessary eng mgt and fuel system upgrades of course. You can even have the engine solid decked with a custom JG CNC block brace. You can check it all out at www.jgenginedynamics.com. When I get the money, thats where I'm taking my ZC. You can't get much more bullet proof than that.
