I am looking to rebuild my gsr block and use an LS crank. I have one question. I will be using all OEM internals except for ARP Rod bolts. I will have crank micro polished and balanced as well as the rods shot peened. The main concern I have is regarding the oil squirters. I know golden eagle makes a block off kit for the squirters. I have read that the oil squirters are not needed if you use forged pistons, what if I use OEM pistons? Will I be better off blocking the squirters than bending them to provide clearance?

 

Yes you can keep them I would recommend it but you'll have to bend them to clearance the ls crank. There are many write-ups on here regarding this issue.

 

Helps cool the pistons (regardless if they are forged or not). Might not be needed for a 1/4 mile drag car that is race only, but I'd keep them around on my daily driver.

 

Since this will not be a drag car and more of a weekend car, I will just stick with the oil squirters. Now I've heard that you can also machine the crank to make room for oil squirters? would it be better to just bend the squirters. I want to do this right the first time.

Also, for those of you who bent the squirters, is there a certain way to go about it? heating them, then bending them? certain angle to bend them at? thanks..

 

Just try not to crush them and make sure they are pointing at the pistons and not the cylinder walls (ie, that will cause excessive oil on the cylinder walls and increase drag...possibly increase blowby/smoking as well).

 

^^ good info

 

you can also get your piston skirts notched to clear the squirters.

 

I wouldn't recommend notching the pistons skirts although i've seen it done in v twin bikes that are stroked simply for the reason that the piston is no longer balanced like it was prior to the notching. A more conventional method is a torch and some light tapping with something of softer material (ie rubber mallet end)...

 

Just install the GE plug kit. I've been running my GSR block with oem LS crank and rods and cast pistons for almost 85k miles now and still don't have any issues. Daily driven (redlined daily), weekend warrior (redlined constantly).

 

^^ hey all-mtr-teg did you ever get yours dyno'd or to the track? i read your write up from years ago the other night! lol lots of good info

 

I guess this explains why all cars with oil squirters came with an oil cooler in the back of the block.

 

my sirII block doesnt have the cooler. it'd be better to have an external cooler anyways.

 

GS-R didn't have oil cooler either. Just the Type R. (Oil/water - oil cooler)

 

obd1 gsr had a cooler, obd2 did not.
