Turbofrancis619

Why hasn't any one tried this this setup on a turboed setup?

i dont know where u been, but dozens of people done that already lol

my *** has been under a rock lol. so what was the out come. Does any one have a link leading to that

The gsr block has oil squiters and ls internals have oil galleries
Do they both do the same job? If not explain?

I see either can be retained 1 with minor mods the other with stock internals
With forged internals in mind why wouldn't i need the oil squiters since i think they dont come with any other way to lube the piston and piston wrist pins?

i plan on doing this same conversion to my gf car

Most forged pistons don't need cooling, unlike cast pistons. But if I recall, it depends on the material and methods used to manufacture the forged components.

Sorry to bring this thread back from the dead just getting mixed conseptions & dont know what I should do. I have a fresh gsr block thats been bored to 81.50 to fit my FORGED cp 11.0.1 pistons I have both cranks for a gsr & LS I also have NEW eagle rods for LS & GSR Should I go ahead with LS crank LS rod swap in my block or not ? I dont like the fact of bending the squirters at all I heard that forged pistons dont need them anyways so I can just cap em off with Golden Eagles kit but then again I put 15k+ on my car a year & beat on it pretty good. I guess u can matching .075 off crank weights or something, but will this affect the balance of the rotator assembly Im going to have whichever balanced regardless, again I have 2 sets of crankshafts as well as Eagle rods so Ls set-up & Gsr all redely available

Stop worrying so much. It's been done quite well, with a lot of longevity. My wife has had hers 2 years with the B20 Crank/rods, Endyn Pistons, GE oil squirter block kit, ARP studs and main bearing kit.

Here's an example.

Enjoy it.. its fine.

Ya but you didnt have oil squirters to worry about lol Ahh you would understand if u knew what my current engine has put me threw over 3k build in Oct smoked & drank oil ever since still has power though prob valve guides

all-mtr-teg

If you use the LS/B20 rotating assemble, get it balanced and use a GE block off kit. I have over 120k miles now since my GSR with LS internals build. I had the car dynoed about a month ago and managed 190whp with bolts ons and M22x cams (cam gears untuned), and that was through a 2" collector and stock cat. Hoping to make 210whp with a 2.5" collector mods and high flow cat and some cam gear tuning.

Wow thats comforting to hear thats a lot of mileage lol do u think I should re-tang my LS h-beam Eagle Rods or are LS bearings sufficent enough ? hmm I guess when they say when u go forged u dont have to have em what do you think about endyns theory about running an external oil line similar to ls vtec to keep the cams/valvetrain cool ? Good insurance or overkill for a daily

99gsvtec

Sorry just now realized ur using gsr block lol

all-mtr-teg

In my opinion, the LS bearings are sufficient for a daily driver. I would be more worried about have the proper clearances than whether or not to use LS or GSR rod bearings.
On the external oil line, I guess it's just added insurance for the valvetrain, but I'm not sure what it will do to oil pressure. Where is the oil line plumbed and directed to? I would call Endyn and get their expert opinion on the matter.

all mtr teg is the man, I'm still in the air between a b20 and gsr block with ls crank but the more I read about your setup the more I think gsr block with ls crank and a 75 shot is the way to go.

99gsvtec

I just like the comfort that the block was designed from the factory to accept 8500rpm plus the fact that I dont have to run lz/b20 vtec oil line or mess with dowel pins decide which h/g to get There are plenty of reliable B20vtec builds I just have 2 complete GSR engines ASWELL as a b18b It would be nice to have the b20 torque I hope to acheive the best of both worlds its killing me to have all these parts sittting in my bedroom & garage my car pulls hard now but I know with my new pistons race head BPI k&n set-up aswell as free er flowing exh I estimate my hp to be just shy of the 220 mark made 208hp with stock JDM gsr piston unported head & bottlenecked exh to muffler & had Apexi power intake/competech ice box set-up

if you left the oil squirters would it make it an ls vtec? or to have an ls crank in a gsr do you have to plug the oil squirters?

99gsvtec

You dont have to run squirter block offs when running an LS/B20 crank in GSR/ITR block but you have to bend the squirters out of the way or the crank will hit, its not a good idea to plug the squirters if your running cast pistons ie oem HONDA ITR etc, But encouraged for forged pistons I plugged mine because I have Forged CP pistons/Eagle rods, when you plug the squirtes it bumps the oil pressure higher elsewhere, Its not really an LSV because have a block girdle etc. With my bore/stroke im like a b19vtec lol

Bump thiss back up! Doing same set up to and was Wondering if i shouls grab ls or gsr aftermarket pistons?

The depends upon the compression you want. Stock LS pistons would only give you 9.2:1, and assuming you want to be in the all-motor forum, you want a bit of compression. Aftermarket is the way to go. But PCT pistons are out of the question.

ok thanks so should i buy b18a/b or b18c aftermarket piston because there's the ls crank n rods in there? or there the b18a/b and b18c aftermarket pistons are the same height and everything?

TheShodan

The difference is in the deck height. When you look for your Pistons, find the ones that are for B18a/b with B16 head or GS-R head. They are typically the same part numbers as the others, but the compression changes a little bit. you'll see that in the charts. For Wiseco, the ones I used were K566M815 (I believe that was the part number). But I liked wiseco's the best.

TTT. Great thread (minus the nonsense in the middle). Thinking about doing a very similar build.

del_slow

Bringing this thread alive again. Great thread..doing the same work on my brothers car and learned a lot...So how are peoples motor running, with or without oil squitters...and so on.
