Greeting,
Please tell me your thoughts about this setup.
Head b16a2, dual valve springs, titanium retainers, ITR cams, ITR intake manifold, vibrant header and straight pipe 65mm all the way out, itr injectors
Block b18c4, bore 81,5mm, B16B pistons, ACL racing bearings, ECU p28 obd1
S4c tranny

Thank you for your time

 

This will be a decent setup for a road course or Auto X or even a daily driver car. I had a similar build in an E.G. Hatch in the past and it made very good power for stock parts. With a B16/PR3 head you'll be a little over 12:1 comp. I used a GSR/P72 head and made around 12.6:1 which is what I was going for since I used SK2 Pro1 cams. What are you planning to use for tuning? That will be the most key factor in the potential of this build. Also make sure whoever assembles the engine checks and double checks all clearances, P2W,P2V etc. As far as power, I can see your build making over 200whp with ease. My setup was 81.5mm PCT Pistons (B16B), shotpeened Stock rods, polished 89mm LS crank, B18C block (JDM GS-R), P72 head, stock ports, Skunk2 Pro1 cams, Supertech Springs/retainers, Type R LMA's, Skunk2 intake manifold (Type R clone), Maxbore GS-R TB, AEM hybrid intake, PLM "B19" header, 3" test pipe, 3" KTeller exhaust to Vibrant muffler. My trans was also an S4C with stock LSD and 4.7 FD. I was tuned on NepTune and that setup made a modest 213 HP and 138 TQ at the wheel on a Mustang Dyno using pump gas and a very safe tune. (Low timing and slightly rich AFRs) Could have easily made 220 on the Mustang which would prolly be 235 or so on a DynoJet. The numbers didn't mean much to me as the track times and street performance were more than I expected from it. Your setup won't have quite as much cam, but will be just as much fun. I predict around 210-215 hp and 130-135 TQ. In a 2100-2200lb hatch that would be mid-low 13 sec ETs and 102-105 trap speeds depending on your DA and tires etc. in a heavier 2400-2500lb coupe or Teg prolly more like high 13's @ 101-103 and either would perform great as a road course or Auto X engine of the tune was done well and the chassis is prepped right. My current time attack setup is much milder and still hangs with some high dollar cars on track. Can't stress enough the importance of a good tune though; stay away from generic chips and all that piggyback crap. Good luck!

 

Also, just so you don't spend extra money you don't have to, Type R injectors are the same as every other B18/B20. They are all 240cc, so any B18 LS/GSR/Type R or B20 a/b injectors will all work the same and give the same result. They will probably be maxed out for a setup like what your talking about, so something like RDX or DSM 450 injectors would be better, or even something inexpensive in the aftermarket like RC310s etc.

 

Thank you for your response, that enigine was made by my two friends and me. On dyno tuning (mustang dyno) this engine has made 225 HP. Engine is in my crx ED9.

 

your prediction is very generous man haha remember this is a b16 with type r cams, not aftermarket cams.

 

looks pretty good. should run well man. high comp b16 engines with ITR cams seem to do well. maybe try a different header like toda rep if you are able to. get it tuned and see where it goes from there!

 

I don't know why I was thinking 1800cc, must have missed the 1.6 part. We'll take about 10% power off my estimates and that should be accurate for a 1600cc lol.

 

Just re-read, you said B16 head, B18C4 block @ 81.5mm PCT (B16B Pistons) Didn't specify the crank, So I assume your using the 77.4mm B16B crank then? That's the only way to make 1.6 out of a B18 block that I'm aware of, because if you had an 87/89mm crank you would be @ 1.8L. Maybe I'm just confused this morning lol.

 

Sorry vtecmasta but you're wrong, read it again. The head is B16 but the block is b18c4, essentially a GSR block so this will be quite a bit healthier than an ITR cammed B16.. The numbers being stated here are not out of the realm of possibility for this setup. Good luck brother I hope to have the time and place to put an older Honda with a built B series one of these days..

 

**** yea im wrong it does say b18c block. sorry!

 

no you were right the first time and i was the one who read wrong. i mean i thought it did say b16 block but it doesnt. my apologies, sorry.

 

Friend has a similar setup. B18c with ctr pistons, 0.5mm over bore. It has about 200whp. My stock h2b setup a few yrs back could pull on him but not badly. This engine has been strong for over 10 years.

Its definitely no powerhouse. Torque is weak on these NA b18cs but overall its a good setup. Super durable, rev it out all you want and it just wants more. A great road course setup for a eg or ek if you're not trying to break records, but rather run a lot and work on times and consistency. With a light flywheel and big rad response is very nice and it will take everything and then more.

Its a light duty race engine, and will not set any track records. But while the turbo guys figure out the cracked block you can head out for another rip.
