Im looking for opinions on What motor you think would be make more power and have faster E.T.

B18b with a race preped LS crank(knifed edged.Micro polished balaced and bluprinted)Shot pined balanced and blueprinted ls rods notched for gsr bearings with arp rod bolts, and arias 12:1 82mm pistons

OR

b18c GSR block with Race preped LS 89mm crank(Knifedged, Micropolished, Balanced, blueprinted) shot pined balanced and blueprinted LS rods notched for gsr bearings with arp rod bolts. and Arias 12:1 82mm pistons

Both blocks would have a Portflow b16 head with supertech valve train(valve springs retainers and flatefaced valves) Skunk2 prostg1 cams. skunk2 int mani. w/SK2 68mmTB and RC 270cc or 370cc injecters. Wilbro 255 intank fuel pump. and JG Edelbrock 4-2-1 with race 2.5 turndown b pipe

I know the GSR will be more reliable but what do you think would make more power and have a quicker E.T. The stock strock built bottom end of the B18b LS or the Built stroked B18c GSR Or some people would say poor mans Type R Please let me know Your opinions ASAP If you read please give me your opinions- Thanx

 

use a gsr block & i wouldnt knife the crank either.

 

how would there be any difference in power?

 

The gsr has a smaller stroke then the ls but when you put the Ls 89mm crank in the gsr it strokes it

 

yeah no ****

so your question is: If I make my motors exactly the same will they make the same power?

How come you wouldent knife the crank Its a all motor build up it might help

 

who cares. i wouldnt want to remove the material. its not like your honda crank is dipping in the oil anyways.

Why did Honda add weight to Type R cranks?

The motors would be identical btw since your using a ls crank in either.

 

Both motors would be the same, what exactly are you trying to ask?

 

Thanx guys for the help Like i was saying i just want your opinon. just looking for for so help in deciding. I just thought it would be different because people call the gsr w/b16 head and ls parts a poor mans type R And I look at the type R motor beeing (Jap Ver) the best they have ever maidand i never heard a ls/vtec refered at that. So the neither could come out in front compared to TQ and HP. Well if not I guys ill go ahead with the gsr build considering my car is a street car abd the stock oil supply(so i dont have to worry about the line) Plus the motor has block griddles so that strenghtens the motor a li

Like i said above Thanks for your opinion Their geatly appreciated
Oh and also since Im not using the ls block I guess ill sleeve it for boost
So here a nother Question?
What sleeves do you think are the stongest to suport super Hi boost
and who is the best and cheapest machiner out their. Once again your opinion mater to me Thanks

 

a "poor mans" R is gsr block/b16 head... nothing to do with ls parts....

as for sleeving

The GSR Block has a lot of external webbing for strength that the LS block doesnt. At 50 psi of boost we are even starting to crack the blocks behind the dipstick. I would run the GSR block for all the support i could get if you have both anyway. Just my 2 cents worth. Good luck

 

Which block are you cracking LS or GSR.

 

GSR

 

are the mains getting distorted ?

 

There must be another problem. There are hondas making a little more power running a full season without that type of failure. But then again at that power who knows. Is this just a one time deal or you've done to more than one block. I will say that I sent a block out to be sleeved and when I got it back it was cracked right in the little valley behind the dip stick. It was directly in line with the bottom of the sleeve. I called them and suggested maybe they didn't runn the the bore deep enough And when they set the sleeve the cracked the block. They didn't say it wasn't possible but of course they didn't do it. Any way I vouch for LS blocks. Thats what we use.

 

Isn't the gsr block height 87.4mm?

So if you put the oem ls internals, won't the pistons be sticking out of the block resulting in a little interference problems especially if your running higher comp. pistons????

 

This block had over 100 passes on it before that happened. The first i had this happen Chuck Sitenger and Kenny Tran both had enignes in there cars the same time. This is totally a power to strength issue, not a sleeving problem.

from what i understand the ls and the gsr blocks share the same deck height.
