i have a 99 ls long block wanting to go ls/vtec but i was wondering if you could install and breather box on the 98-01 b18b1 since they do not come with one, and if so? does any body know how much they run? or how hard it is to install?

 

The 98-01 LS Blocks did not come stock with a Breather Box. What you can do, is buy a Enydn or Z10 Motorsports Breather Box Kit. The other option is to pull out the 2 Oil Gallery Plugs in the back of the block, replace them with 2 from the Prelude which hae nipples on them, and run it into a vented catch can. Much cheaper. There is a thread with the part numbers to use and goes into detail about it.

 

is there any way you can help me find that thread? it would really help me out alot and thanks for the info its exactly what i was looking for.

 

I also want to know if i could bolt a gridle right into my LS motor?

 

anybody??

 

You can buy a girdle but it will require machining. I am pretty sure even the z10 girdle needs to be machined to fit correctly. If you are not building a really high compression motor and shooting really high horsepower, I would not worry about the girdle.

Heres the stuff you would need if you want to piece one together for your catch can






This is how it looks on an lsvtec.

 

Can you explain what the parts are in the Honda bags? also like what they are for, how do they work? i would need some sort of tubing to go along with it and a catch can, is there a non-expensive catch can you perfer for the cheapest route i really doubt you need something really expensive being only a catch can nothing fancy, just something that does the job.

 

im getting a complete jdm b16 long block from a buddy it has fried pistons/rings he said, i really dont have use for any of it but the head for he's selling it complete for 300 bucks. Im not trying to build a really high powered motor just something reliable and has some power, its gonna be my daily driver and i read up on the link you gave me for how to build a reliable lsvtec but in that thread his motor looks like alot more upgrades than im looking for i dont think imma get the block honed or sleeved or get the head ported, im jus gonna use what i got. imma get arp head studs and the lsvtec kit, do the stock ls pistons do okay? i just wanna basic setup with vtec. and does anybody kno what kind of power you will get out of this setup with stock ls pistons with all stock b16 head internals. just a guess at what imma get out of it.

 

The honda bags have the actual product in what each bag has next to the left of it. Those are the two nipples you would need to vent your block with and the one above is the seal that goes with it. Yes you do need some sort of rubber tubing. Lowes is cheap. I bought my endyn catch can itself for like $50 shipped. pieced everything together and cost me less then $100.

 

Thanks man, too bad i cant read the part numbers on all those bags imma have to try to figure it out, does anyone else have any info they can share with me other than those parts, like what kind of hp i will be looking at when im all finished? im using stock I,H,E also.

 

No, a Girdle just won't bolt onto an LS Block. If you wish you run a Girdle, you will need a GSR/ITR Oil Pan, GSR/ITR Windage Tray, GSR/ITR Oil Pick Up, and GSR/ITR Main Studs.

As far as running one, it depends on your application. Its not really needed, but if you plan to Road Race/Autocross it, then it would be a wise investment. I really want to run one, however, the cost to get all the GSR/ITR Parts just to get the Girdle to bolt on is really expensive.

Also, not sure why one of the posters said you would have to get it machined. If you get all the proper parts, you shouldn't have to get it machined.

 

Thanks for the input EdSales, i dont think im going to use a Gridle then, im not going to be track or any kind of racing with this motor, just daily drive, but i do hope it will beable to keep up or be faster than a regular gsr. Would anybody know?

 

No feedback? Im out for the night ill check back on the thread tomorrow or the next day hopefully i have some more replies, thanks everyone.

These are the Honda parts, the one in the white bag you wouldnt need for your ls block since you never had the black box on the back of your block.

 

.That was my thread. If you do ANYTHING in mating a vtec head with a non vtec B block it would have to be ARP rod bolts. That is of course only if reliability is a concern to you. All other oem parts will hold together just fine with proper tuning.

 

130-150 out of oem LS bottom. Waste of time IMO.

 

Stock LS Pistons are pretty well worthly unless you plan to Turbo or use Nitrous. You could get the B16 Pistons pressed out and put the B16 Pistons on the LS Rods. I would recommend getting the LS Rods resized for the 8mm ARP Rod Bolts.

RS Machines also makes a good set of High Compression Pistons for 300 Dollars.

 

Endyn Kit or fab your own. You can vent the valve cover also but have to weld on the bungs. As far as a girdle goes. I used a GSR setup in my LSvtec. EVERY girdle will require a line bore and hone as the LS block never had a girdle. ARP Rod bolts is a MUST if using stock LS rods. Use a Aftermarket intake mani and a GOOD header and exhaust. I used B16 pistons also, which raises compression but still very steetable. Bump compression and make sure it can breath. It will be fast

 

Thats it? stock LS has more than 130 stock, why so low?

 

low compression.

 

Power: 142 hp (106 kW) @ 6300 rpm & 130 ft·lbf (180 N·m) @ 5200 rpm is what stock is, so why with a vtec head only be 130-150, Just the head it self flows alot better than a non-vtec head i dont understand why it will loose hp. I was guessing 160hp with stock ls pistons. But i seem to be wrong.

 

It does? I usually see them stock dyno 115-125.

 

Ok well i wasnt going by whp, so it really its a 20ish hp gain overall. That is what im looking for. Thanks

 

Also i was wondering do i have to convert to OBD1?
