Well I finally got my b20 block....what do you think of the z10 block girdle thing? Any opinions from users or ex users. Is it a necessity? I am building the bottom end...is that enough to rev to 8500rpm?

 

Throughout my research (1 1/2 years) I have found that more people use the OEM GSR or Type R girdles. Reputable sources (qualified metalurgists) say that the z10 girdle is made out of a softer aloy, therefore not being as strong as OEM...
The OEM route is cheaper too.

 

I would think that you could go with a stock gsr girdle and it'll work well.
As far as revving your motor. You will need valvetrain too, you didnt mention this and I'm sure you know already but you said what else is needed.

 

i designed the z10 girdle. If you do a search you will see that in order to use the girdle properly you will have to heavily modify your block.

If you use the z10 girdle by simply bolting it on as outlined by z10, you *WILL* do more harm then good. I know of many HIGH power cars that use no girdle, without any problems.

 

<--Im doing a Ls/vtec I am also deciding which is better z10 girdle or jsut use a stock gsr/type r girdle on my ls block. Block is fully built. Any suggestions.

 

Coming from the man who designed them...
Im going OEM-insurance isn't a bad thing.

 

That's why GSR Motors with LS Crank own.

you are correct sir!

Even after designing the girdle, thats what my motor is, b18c, b18b crank b18c head.

now civicdrgrcr, take the time to re read what i posted. The answer does not matter if youre built stock semi built or using aluminum rods, it doesnt matter. If you want to use a girdle, use a GSR block. If you want to use a girdle on an LS block, without heavy doweling, you can/will do more harm then good, end of story.

 

what's so special about this configuration?

 

B18B crank = longer stroke?

 

the special part about this setup is that you get all the advantages of an LS motor, but the strength of a properly designed and doweled main caps and girdle. Do all the work to an LS and z10 girdle or factory girdle it doesnt matter, its not gonna be as strong as a factory GSR block.

BTW stay away from type r blocks from acura. they are just re-mans.

wasnt there a post on here about the pros and cons about putting a ls crank in a gsr block? there was a topic about an article with mr spoon in some magazine saying its causes too much vibration or some **** like that ?

 

'Mr Spoon' was referring to B20a Cranks (95mm) in GSR Blocks, with super-short rods...giving like a 1.4:1 R\S Ratio.

We are talking about 89mm LS Cranks, in a GSR.

gio, i told you about this 2 years ago, there is nothing at all wrong with doing this. why wont you believe me???

the ls and gsr blcoks are identical with the exception of an oil passage and main caps. Machining tolerances and bolt centers are identical.

 

Understood better now! I re read it.

So which girdle should i use on the ls block. Also if you block is deck plated would the longer rods hit the girdle??

to be honest if you have a deck plate, the rod/stroke ratio will be so good you wont even need a girdle at all because there will be so little vibrations.

if you need the security of one, do it like InlineFour has outlined, its the only way to go without causing problems!

 

What rods would you use if you had a LS crank in a GSR block? I am thinking LS rods...

 

no i never said i never believed you, it was just taht i saw something on this board that they were talking about ... you know i always beleie what you say.. i never doubt you..

 

my bad. sorry...

 

correct, LS rods!

 

lol gio youre too funny, youre my fav car person in NJ, and i appreciate all the times youve helped me out with my car.

Once i get back to NJ in dec. ill build that motor for you, just try to get the machine work done now, so when i get back i can just build the motor for you.

 

no prob geoff.. a think ill send my head to port flow her 250 for a gsr head i dunno man? im still thinking about it , im waiting from portflow to respond to my email. and thanks for all the times you helped me out too

 

Just trying to figure out what kind of harm would it do to the engine? I have installed one on my block, but the car hasn't been ran yet at all. Can you give some advice on what kind of harm it will do.
