Hi to all, may i ask if stroking a B16B to a 1.8L does it have the same performance as a B18C5 since B16B is a destroked version of it?

And what about stroking a B18C5 to 2L, does it have the same torque as a B20 vtec (b16 head with b20 block) ?

If there is different in the above, wat are the different?

Thanks alot

Depending on what pistons you use (ITR or CTR) you will have the same or better performance of the C5

Stroke generally yields a couple to few more ft lbs of torque than bore (comparing both in identical displacment) but your torque/power curves will be very different between the 2.

Do both (bore and stroke) and have the best of both worlds

 

thanks for yr reply, so does it mean i can stroke and bore my b16b to a 2L and enjoy the best of both world? Will my lower block be too thin and won't be able to last long? What about the Hp and torque compared to a b20 vtec? sorry if i ask too much and is stroking my b16b to 2L too wishful thinking??

 

if u are going from 1.6 to 2.0 u wil have to resleeve. and maybe highten the deck??

 

so does it mean if a b18c wanna stroke to 2L it need to resleeve also?

 

stroke and sleeve are totally independent of one another. You can use a 95mm stroker crank in an 81mm bore B-series motor if you so choose.

 

sorry for my ignorance bro asubennett but resleeve is consider re-enforcing the block wall right? other than resleeve wat option do i have if i wanna stroke my b16b to have the torque of a 2L ls/vtec?

hi bro innovation, are you saying if i put ITR piston into my b16b the results will be better than a b18c5?

 

ooo

the standard bore x stroke of your engine is 81 x 77.4 mm

the standard bore x stroke of an itr is 81 x 87.2 mm

the standard bore x stroke of an b20 is 84 x 89 mm

basicly, if you want a stroker kit b16b-&gt;b18c you'll just have lengthen your stroke from 77.4-&gt;87.2mm (b18c crank). combine this with your old ctr pistons (pct's) and you will have more compression then a b18c5 (pct's are the highest compression oem-pistons available for b-series 81mm)

if you want stroker kit b16b-&gt;b20 you'll have widen your bore 81-&gt;84mm, and lengthen your stroke from 77.4-&gt;89mm (b20/b18 crank). the stroke is "no problem" but you cannot bore the stock sleeves to 84mm. you'll have to resleeve (expensive) and bore to 84 (86mm max). and then you can't say you have the same torque of an b20, depents on your head, cams, boltons etc.

you'll also need to run aftermarket pistons as there are no oem high compression 84mm's

does high compression always translate to high hp? And the other way around?

A motor with the exact same mods. But one with higher comp, does it necessarily mean it will yield higher hp?

 

Typically one full point of compresion will net you 5-6whp across the board. But there is so much more that goes into it than that. If you have too much compression and not enough cam you can hurt power, vice versa with too much cam and not enough compresion.

The best advice I could give you is using the minimal amount of compresion for the application you are building for. Lower compresion is more convenient, easier on the motor (less cylinder pressure, less heat).

 

let's say my intention is to put a toda spec c into my stroked b16b, will putting in a itr crank with my old ctr piston give enough compression? or do i need to get the 82.00mm forged piston to get more compression? And have anyone experts here used the toda sports injection kit before? is it really worth the money?

 

An ITR crank thrwoing around your PCT pistons will yield plenty of compression for TODA SPEC C cams. That will be a great set up. Plenty of useable power.

 

Or you can use an LS 89mm crank in your b16b since it has the same deck heighth as the b18c and have a torguey b16. i am pretty sure the b16b is identical to a GSR/ITR block with the exception being the stroke. THis means anything that can be done to the B18c can be doen the B16B. I myself am putting an LS crank in a GSR block at this time.

 

You could use the LS Crank as well. Then you have to buy new rods also. You also will not be able to use your stock crank girdle without machining it for fitment. I woudl stick with an ITR crank. It is more plug and play for you application. Will also allow for higher revving as your R/S ratio will be much better.

 

Ok, now i roughly got in mind what i will do to my b16b...

Crank - ITR (for stroking to 1.8L)

Rod & Piston - CTR (for compression and R/S ratio)

Camshaft - either TODA C or Skunk2 Stage 3 (is the skunk2 for drag?) As i'll be going for track so is TODA a better choice? or is there a better option?

Valve Springs - TODA (any other options?)

Titanium Retainers - TODA (any other options?)

Adjustable Campulleys - TODA (any other options?)

Header - Jun JDM stainless B16/B18 Civic/Integra 4-1 2.5" http://cgi.ebay.com/ebaymotors...33631

Intake - TODA Sports Injection Kit (is this Intake worth it?) http://todaracing.com/products....html

With my above kinda engine set-up into my EG6 (track car), wat are yr views and comments on the parts i'll be using? and if i have missed out something?

Thanks all the experts who have helped me with my questions. I really really thank u all and i sincerely appriciate it.

 

Toda does not make titanium retainers. Use Ferrera or Supertech or Portflow etc.... Also, if you are road racing use the Toda cam. The Skunk 3 cam is a big 2 liter motor 7,000-10,000 rpm range kind of cam. It has stock like primaries that are not ideal for big midrange numbers.

I personally wouldnt do that header, I mean it looks as if you plan on spending a decent amount of money elsewhere why not get a good header as well? RMF,SMSP etc.etc.etc. even a TODA would be great choice

And for ITB's Jenveys and TWM's are nice and are a bit cheaper than the toda's or you could go the DIY route

good call I overlooked that detail.

 

itb is not really meant for street right? more for drag race right?

sorry guys, but other than getting my ITR crank and rod from spoon, where else can i get these 2 babies? spoon is like selling 1k plus for the 2.

You could grab them both in HT's classifieds.

 

sorry to troubled you again bro but is it better to get a new set of ITR crank and rod or is it ok to get used ones? Do i need to change the bearings if i'm getting the used ones?

I've search the forum and found that very very few people here do anything to their B16b, is it because it's not wise to do it? When people say b16a head with b18c block, is it the same as B16B?

Sorry to all for asking so much but by changing my crank n rod i also need to get gasket isit?

 

The reason most people dont do anything to a B16B is beacuase it is a JDM engine that isnt real common here. Most people would rather buy a b18c because of the displacement. B18c's tend to sell cheaper than the B16b.

You can buy a used crank and rods as long as they are in good shape. Yes you will need new bearings when doing this kind of work.

As for gaskets almost all B series Vtec engines are the same.

 

just went to see a illegal street race just now, between 2 done up 2.2L ls/vtec. Man are they fast. The winner is using jun stage 3. I was wondering if my this set up using toda c will be any match for him. i know my displacement is smaller than them but will a done up 1.8L win over a 2L?

does using a lighter rod and crank make a big different in the power? me thinking of getting the lighter eagle crank and rod with stock dimension fitment for Honda B18C engines (including TypeR)than the oem rod.
