B16B stroked to 1.8 with TODA parts...

98-100 octane 12.5 CR should be fine :nice: and yeah a lot of kids here have a K engines, i could have had one for 2500 but i refuse to buy stolen goods :angry: average price on the swap is 6-10K!!! installed.

WTH!!!! you said NO to a K20A for $2500????!!!!! You know these engines here cost like double and a bit more... :angry2::angry2: you could have gone up to 270kmph N/A and get your car CRUSHED like what they do in California... :lol: joking....

Yeh, if I knew the exact process then I might just go hunting for a K20A. But yeh, 6-10K install is pretty heavy... :(
 
yup i dont buy stolen stuff, i could have bought a b18c gsr for 800, i said no to that as well.
 
Blinx, What pistons do you recommend with TODA SPEC B cams? Also what Valve springs? SPOON? TODA?

with toda cams i suggest full toda valvetraing: timingbelt/valvesprings/retainers/thin headgasket/etc... pistons are really up to you, it depends how high you want your comrpession.
 
i no over here its cheaper jus to buy the b18c engine than it is to stroke the b16b to b18c...i think the b16 wiring loom can be used all you'd really have to change is engine ecu fuel pump an possibly drive shafts

nope, you can keep the same axles, unless you get a 98+itr and yeah you can use the same harness and ecu, but its better to upgrade your ecu. and you DONT need a fuel pump.
 
Whats the point of having a B18C in an EK9? It'll look like a conversion...


Blinx: Thats the problem, I don't know how much compression would be suitable for a street car... Any off the shelf pistons you reccomend?

the only external difference is the stamp on the block :nice:

i think its best to discuss with who ever is tuning the car, if you have 98-100 octane available, i think 12.5:1 is good, as far as brand ROSS/JE/WEISCO/ARIAS/etc... all good :nice: you'll probably have to buy a piston for the ITR which is the same, only compression will be different becuase of rods/crank. so say you get a ROSS piston for an ITR with a CR of 13.2:1 if you put that same pistons in a b16b it will be 12.5:1

or it might be easier to get pistons for a GSR, then just know the differene in compression is 1 so a 11.0 cr piston for a gsr will be 10.0 in a b16b, hope this helps.
 
Hmm, Toda has 82mm forged pistons which will up the cc from 1595cc to 1635cc. Is this enough?

too big, you'll need aftermarket sleeves, the largest you can go on stock sleeves is 81.5mm. you can try to push it if you want, but thats up to you. if you do sleeve it though, you can go to 84mm and have a short stroke 1.8!!
 
To me the reason for 10,000 rpms : The sound. With a proper exhaust system and good power the sound is a full bucket of win; no point waiting 30 seconds for the engine to rev to 10k. But it sure sounds great when it revs right up to 10 easily. Ive heard race prepared engines going 11krpm and it was just insane. ;) And this being a forum of VTEC fans, Im pretty sure a lot of us are obsessed with revs.

Im the sort of person who focus less on practicality or efficiency, but more on the overall driving feel. Which is also why I love Alfa Romeos...

Well with 12.5 compression there's going to be a pretty small margin for tuning errors, and wear and tear will be just higher. Knocking isnt going to be the only issue. Otherwise manufacturers would just go crazy with it.

i think you need to buy a sportbike :nice:ive driven honda's that redlined at 9800rpm with a close ratio gear set, and ive driven honda's with 8500-9000rpm redline that were faster. also if your worried about 12.5 CR being hard on the motor you shouldent even think about 10,000rpm cause thats A LOT more stress. a forum of vtec fans we are, but im obsessed with power :D revs are important too, but no more than 9000rpm imo.
 
I know some of you guys wanna keep your engines N/A but the money you will spend on parts and labour for up-rating camshafts and all the other necessary parts wouldnt you be better off buying A turbo for it and getting some serious hp gains for the money. As seen from other threads on this site the b16b should be capable of boosting to 280-300bhp with out need of changing internals that sounds pretty good to me:D

agreed! especially with the high octane gas offered in most other countries, im limited to 91 so even if i mix in 100 its still only 95 :angry2: or if your gonna stay NA sell the b16b, save up some money and get a k20 :D

Would 81.5mm be safe? Or create a bit more wear? TODA has 81.25, 81.50 and 82.00mm with rings etc for around 900-1k :( Which one should I get for a CR around 12 or no more?

JayH: i like the sound of that too, lol

Vtec6000: some people just love the feel of N/A which can be more satisfying, SPOON also stays N/A. If I wanted to kick ass with turbo power, than a Skyline GTR would be enough for me... hehehe... i do have another forcefed car, and I really like the technology and feel of Honda's VTEC!!!

Blinx: K20a + install is way too much headache and damn expensive to install on an EK9... I do want my A/C or my gf wouldn't be happy :(

Check out ORIDO's reaction in this video, he's scared!!!! :lol: who wouldn't be...

i would get the 81.25mm it will increase your compression to 11.1 they dont make anything higher than that.

go to products, b16a/b16b,b18c, pistons.

I can get OEM CTR 81.25mm which would be cheaper :woot: but TODA ones are balanced, does it make much diff? What would the compression be for 81.50mm?

if you wanna save money you can just replace your piston rings and do this:

-flat face valves
-mill the head .020
-2 layer head gasket

this should raise your compression to: ~12.0:1 :nice: i dont see any need to get forged pistons on an NA motor, unless your really planning to abuse it.

Great advice, I AM keen on saving money...:thanks:

Yeh, I don't think forged pistons are not worth the $$ and I just want to raise the compression to suit the cams.

when you say 2 layer head gasket, what do you mean? how many mm thick?

I've got quite a few choices here and the 81.25mm pistons kit is around 450. Flat face valves is a good idea but I don't have access to them in AUS... do you sell them? How much are they?:thanks::thanks:
