My 2L B-Series N/A Project

83mm you mean? ha ha ha

haha chris... nasib kita serupa...

Its a sad week for me as when my mech drop the engine in to the bay, and we fill up the radiator with water and waited a while and noticed some water sipping out of the block near the dipstick between cylinder 3 and 4!!

A closer inspection revealed that when the sleeved was pumped into the block it created stress crack which was hairline :confused_smile:

As the block is a major part of my build, i will have to save more money now for a new block... So it seems like i have to hold on to my project till i have funds for another sleeved block which i don't think will be any time soon as i'm also due to re-build another engine for mme :shcokedcamo:

Eh? the block died already? I dropped by to pick up some stuff and it was not in yet, now it's gone already?

My condolences, chris... well, what might have been.

Good luck in your MME engine.

Just curious... you're still using the stock S80C with the 4.785 FD? Or changed already? no need to let me know the ratios, just wondering if you got them changed.

83mm you mean? ha ha ha

no laaa... i mean my block die like chris block... hairline crack at the liner...

 

[dcloo]

no laaa... i mean my block die like chris block... hairline crack at the liner...

then can upgrade to b18c
its a good reason to upgrade ur car now..:cyclops:

 

[hattech-v]

now downgrading... time to rest a bit....

Yup, when you drop by, it was already preparing to assemble. but after assemble and before start up saw water leak through the block! hai...

I'm not running type-r gearbox. Ratio all change except for 2nd is OEM. If you gear ratio let me know. Spoon ratio is too close for road use and too close for 1.8cc-2.0cc.

Yeah.. I know.. someone here is using it already. Spoons are really close. I guess it was meant for their 11K b16B. Not a good option if you're rev limited to 8-9K.

Cruising at 5th is with 4.5FD is 4K+ at 100kmh. :P

What you mean by "you gear" ratio? I assume it's a typo.

Bro, you want to sell your crack liner block to me as besi buruk?? :angel_smile:

Seriously, if it is the liner crack only, please call me or pm me. Wanna R&D a bit.

Wah.. so fast making a move already.. (O_o)

I meant if you need gear ratio let me know.

I meant Spoon ratio too close is because at gear change the revs drop too little about 1400-1500rpm(so little coz 1.6 no torque and need to keep rev high). You are right, ratio was intended for short stroke B16B revving to 11k rpm .

For both road and race use with good torque, ideal is a ratio with gear change rev drops about 1800-2000rpm. This saves a little gear change time.

Thanks for the tip. Another way I think would be playing with sub 4.4 ratio FDs, but that would be counter intuitive, wouldn't it?

i think spoon not too close compared to kaaz or ats (their original spec...)
spoon i think is good for big cc.. while ats/kaaz good for 1.6

Nope..

Spoon 3-5 Ratio
3rd-1.591 3rd-4th RPM drop 1660rpm
4th-1.280 4th -5th Rpm drop 1640rpm
5th-1.033

ATS 3-5 Ratio
3rd-1.652 3rd-4th Rpm drop 1770rpm
4th-1.308 4th-5th Rpm drop 1780rpm
5th-1.033

KAAZ copy Spoon ratio so they are similar.

If you ratio itself ATS is indeed closer which mean the 3rd and 4th gear has less top speed.

But what i meant Spoon is too close coz at gear change, the rpm only drop 1600+rpm which requires you to do more gear shift and change.

Where else, ATS speed on each gear is slightly lower but rpm drop is almost 1800rpm which allow you to rev each gear longer before gear change.

I found a custom gear set from USA which provide a little more speed than Spoon and rev drop about 1950-2000rpm which is ideal for road cars and powerful track car. Should be testing them soon in July :regular_smile:

 

[shiroitenshi]

Chris, the ratios based on what FD?

The FD changes the rev drop numbers a little.. I think spoon uses something like 4.4 or higher for their FD in their 11k rpm B16B, because if you saw the vid of the test, it looked as if the speed isn't that high, and the rev drop is somewhere like 2K, I think.

Replicating that setup on a 9K limited B series did not get good results, though mix and matching helped a bit after that.

And one more thing that made me go (O_o)
The first and 2nd are like 2.XXX, and 2.1XX? (I'm not sure the exact numbers, but I think it was a bit extreme.. what kind of FD they expect us to use?) 4.9/their highest ratio? That would seriously kill speed on a 8-9K rpm limited car. (which may be a bad or a good thing.. I'm no track driver!)

Personal thought is, it seemed like they made it especially for their 11K rpm B16B.

 

[chris2000]

As far as i know and tested, FD does not affect rpm drop on each gear. FD just alter the entire gear ratio speed per gear.

It is the gear ratio that affect each indivual rpm drop and speed.

Stock EK9

3rd-1.458 3rd-4th rpm drop 2050rpm
4th-1.107 4th-5th rpm drop 2000rpm
5th-0.848
