Here is my dilemma. I have an EG HB that I use for track events. I am thinking of putting a new engine in it. And this is what I can’t decide between:

Option 1:

Head:
Toda Spec D cams
Toda valvetrain
Toda ITB’s
P&P

Block:
B16 block sleeved to 84mm and B17 crank – basically high reving 1800cc engine
12.5:1 cr with forged rods
Strengthened and balanced for high reving ability

Tranny:
ITR with 4.9 final drive

And all the other bits and pieces to make this thing run in the 11K rpm range.

Option 2:

K20 (Type R sepc) Stock for now.

So what do you guys think?

All opinions are welcome.

 

well even though im considererd a newbie due to my post. I would getthe k series its going to last longer than the b.

 

k motor all the way

 

if you looking for a track car get the built B motor. Its a track car, the motor lasting to 100,000 miles and more is not an issue to consider

 

boxattack, what do you mean it will last longer? Its newer dont mean it will last longer; how long do you plan on living? Anything before B series motor is made for cutting grass. A B series can make over 200whp easy, so do you think in the future everyone would need a 300+whp car? I do agree with going with the K though. Type R power is the ****. Go with the R, kpro with a good header.

 

that is a pretty tough decision. I would revert to saying money but I don't know if that is an issue. However, installing the K will be LOTs more work than then B. I would go with the B and wear that Bitch out then put in the K. Sounds like the B will out perform the K anyways. My 2 cents.

 

Your answer lies within your question.. You are comparing a fully built B vs a stock K. The total $$ bill for the B series motor will be way over 10K for sure unless you get special pricing.With the same amount of money, you can be making close to 300whp on a kseries all motor.

Let me give you an example.. Last week I bought a TSX motor that came from a car that caught on fire...

Here's the motor I received



paid $500 for it...

I took it apart and I am sending it to ERL performance to get 89mm sleeves

My plans are stock 89mm crank, 89mm pistons with around 12.5-13.0 compression, 52MM TWM ITBS, and cams with stock head. In my opinion this is going to make at least 270whp with hondata K pro.

Sleeves $1500
ITBS $2000
cams +valvetrain $1400
pistons $500
rods $800
misc like type s pump, ACL bearings $300

Average high retail price for all these parts so you get an idea.
New accord bare blocks k24a go for $500 from your honda dealer. Type s heads go around $1000 and 6 speed transmissions go for $1000 + $800 quaife LSD.

When adding parts like sensors, gears, chain, water passages, hoses, oil pans, wire harnesses, chain covers, bolts, alternator, starter, etc... YOu are looking at around 9-10K and you still have to put it in the EG with mounts, axles, headers etc...

That is if you are looking for a K series all motor monster... So in my opinion, the b series combo you described will be as much if not more since the toda ITBS are $$$ on their own.

I was bored last night and played around with fitment to see what I need to cut to fit the ITBS

That's a sig-line quality quote. But I don't understand...

To the original poster, are you set on that particular B series setup? 11k rpm's won't be reliable under any circumstances. Why the need to rev so high? What are your HP goals?

 

Nikos, All that and using ACL bearings? Wouldnt you want a fully measured bearings for better clearance than just Universal bearings?

Or are you cutting the crank to compensate for the differences in clearance of each bearing.

Exactly, ERL does this to all the K series blocks that get assembled and sleeved in house.

Check out the spec sheet on my last K24a block that was built last july. Forgive me if I erased the part numbers of the bearings but I cannot give out 100% of the recipe.. Only 99% of it

Check out the quality of work done by ERL performance. Excellent quality work and fast turnaround.. I believe it took them one day to get the pistons, rods, bearings and crank installed in the block. This is why I don't understand why people feel like they need to wait on someone for 12 month to install a damn piston in their block

 

if u need a motor now for ur race season then go with the b if not and u can wait a whyle then i guess go with the k

 

Well, The K is here to stay, so I would say, go ahead and get it. I mean in a year there are going to be so many different routes you can take with the K. It definatley has potential. Most built B-series are making what the K makes stock. But thats just my $.02

 

My stock K with cams has take down many built H and B series engines. Hell just look at the difference in what the head flow. K all the way

 

Interesting comments. Thanks for all the replies. The only thing that I am concerned with the K series engines is the rod strength ( I heard of the rods braking at high revs) and the smaller oil passages then the b-series ( this causing oil starvation on road racing engines). The two issues may be actually related, I am not sure. Any thoughts on this?

 

In regards to the oil problem I think if you have ERL do the machine work they have most of that figured out to the point that it isn't a problem anymore.

 

i got love for the b series, but k produces mad power plus its the new age.

 

If I had no specific preference for motors I'd go with a K. It's just the future and will be a good foot note in history when street driven N/A 4 cylinders made 300 HP. I just wish Honda made another series besides K. K is cool and all, but so were the B and H back in their day and I loved the options of going for different series and the friendly competition in between them.

However I do see that it's in Honda's finacial interest to stick to one series that retains many manufacturing similarities across all car lines.
