Honda B Series Engine Best Mods & Upgrades [Tuning]

Modifications for the Honda B series engine. We cover the best upgrades for your B Series to help you maximize your investment in your Honda Project car.

The best engine parts, in our opinion, are those that provide the best value for money. Popular B18 parts will not influence us; they must be cost reasonable.

Engine Upgrades for Your Vehicle

Mapping - remapping via aftermarket ECUs and piggyback ECUs are great upgrades on the B series.

Fast road cams are one of the most significant mechanical upgrades, but they must be fitted by someone who knows what they're doing, and they're not always easy to come by. However, you might be able to find a local outfit to regrind a standard camshaft.

Note that many of these mods will NOT ADD POWER ON THEIR OWN in most circumstances, although they can aid boost power after other mods by removing the restriction.

Turbocharger and supercharger upgrades - forced induction is the most efficient way to increase air supply, allowing you to burn more fuel and produce more power. It is one of the most expensive modifications, but it delivers the best results.

Porting and flowing the head's goals are to get air flowing into the engine while removing flow limitations and turbulence.

Intake manifolds, Sports exhaust header/manifold, Fast road camshaft, Panel air filters, Remaps are common stage 1 changes.

Stage 2 modifications commonly include: a sports catalyst and performance exhaust, a ported and polished head, fuel pump enhancements, a fast road cam, and high flow fuel injectors.

Engine balancing and blueprinting, adding or upgrading forced induction (turbo/supercharger), competition cam, internal engine modifications (pistons/head/valves), dual charging conversions are common stage 3 changes.
B series turbo upgrades and turbo conversion kits add substantial power to your project.

I love my built b series . It seems to really like Nitrous express all controlled by a Haltec ecu and Mad scientist auto behind the key board. It’s sleeved cams springs retainers rods etc. It does pretty good for a NA car and I can still drive it to work

[G_B_]

Phenomenal explanation man. I know nothing about these motors and this was a very nice video to provide me some direction

[llgvpko]

B18c1 I put a p73 type r intake manifold on a p72 head alot of research
S80 lsd type r gearbox
Has a neptune ecu with 2step
Has arp head studs
Pcv deleted with crank case an rocka cover breather set up
Goes good revs 9k rpm all day
To many rules in New Zealand to get it certified if i decide to go turbo
Its a fun db8 an reliable an cheap on gas

[TAkEdA]

thanks for the info, im a total noob and have a 96 integra with a b18b in it. After adding intake, header and exhaust im really noticing how much i need to tune soon. Probably a vtec head thrown on in the near future. This is great info for the dumb guy way behind on these engines.

[daddymulk]

In the brochure the Mugen turbo kit for Mk1 CRX came with replacement ECU so it was all setup ready when full kit fitted

[ce]

B20B long intake 97 AWD crv. Have a nice header from PLM 2.5" collector, stock but new cat, 2.5" cat back. Exhaust gets the most results on B series. I've also had 95 GS-R 1.8 VTEC had a lot of bolt ons but the VTEC engines need the 4-1 really wakes up the top end.

[civicstar]

Jdm b18c
Skunk2 tuner 1 cams
Skunk2 intake manifold and 70mm throttle body
Type R p73 pistons
Dual valve springs added to exhaust side
Type R single accessory crank pulley
Lightened flywheel (9lbs)
6 pick clutch

With cams matching a larger throttle body team up well

[adriansanchez]

I have a D 17 A and it’s terrible. I’m trying to do a swap. I can’t decide what engine to go with. Thank you for all the information and lotta information in this one video.

[LilTemha]

I got a obd1 chipped b18c7 with k and n aem intake high flow cat and 4-1 headers making 170 whp
Really wanna stick to all motor, might get 68-70mm throttle body and an intake manifold

Iv a b18c4 engine in my mb6 vtis. Iv got the skunk 2 cams, skunk2 inlet, whale intake, tegiwa 4.2.1 header, toyosports exhaust 2.5, decat. I changed the box the a s80 4.4 fd, iv the p73ecu. Is their anything eles you'd suggest. I want to make it really nice without turbo. Or would it be cheaper getting the b18c engine. Any kore mods and advice would be really appreciated

[clplusp]

So i just recently bought a 1990 Integra GS. Its fully stock. From what I understand, there’s no real easy mod to add power as any setup requires a very extensive list of supporting mods. I bought it hoping id be able to add a few mods for 160-180 whp. I now know it’s not that easy

[nathang]

B16a with a supercharger tuned at 245hp rebuilding it currently and looking to go around 300 horsepower if I get a smaller pulley and some cams do you think I could be making close to that. Looking to bore out the pistons and chuck in larger forged pistons a lot of upgrades I haven’t stated trans has also been rebuilt snd strengthened so should be able to hold the power I’m planning on making is a street car also!

[beastman]

I had a b 18b1 in my ej1 car was a savage just got a eg and put in a b20b should done more research not the same

[MunchPremium]

I will turbo it till it brakes and get a k series 😅

[cheeseburguhgaming]

i rather just go full bolt on Intake Mani Air intake Flywheel Transmission Change with a Simple engine swap instead of doing Frankenstein's
