Why don't you try it out and let us know

Re: type R rods in ls block?
 

well I would but he already spent a ---- load of money on it with out researching anything and I really wanna know if it will ---- everything up the first time he cranks it over

Re: type R rods in ls block?
 

No it wont. The rods will be too long. Ls rods are shorter because the crank has more throw. You can swap type r and gsr ---- but the ls will only swap with the b20 rods.

what if he runs a gsr or type R crank then?

Re: type R rods in ls block?
 

Then it will work fine. You can find a crank easily on Honda Tech for just over $100 shipped. You might just want to keep the ls crank and buy ls rods instead though. With the ls crank youll have 1834cc of displacement and with the gsr or the type r you will only have 1797cc(i think those are the numbers). It doesnt sound like much difference but there is a decent ammount more torque with the ls crank. If your going to be revving really high just make sure to have the ls crank balanced.

the type R piston will fit a LS block.
i know i did it.
and for rods all b series rods are interchangeable. its u got to mach the baring size up
i have put GSR rods on a LS crank
what u have to watch for is the clearance the part where the piston meets the head. the longer the rod the more compression.
rod lengh i am not to shour about i know SI rods are the smallest in lengh.

Re: type R rods in ls block?
 

all b series rod arent interchangable. LS and B16a rods have a fatter piston end then GSR and TYPE R.
the crank ends are the same though. you can machine the LS or B16 rods to accomodate the GSR and Type R pistons.

simple rule, crank and rods need to be from the same engine

thanks guys that what I needed to know I wanted to make sure they would hit the head or bend valve or over all just destroy every thing

ITR rods are glorified GSR units, lovingly bukkake'd at the factory, with a big pricetag slapped on.

For what ITR rods would sell to a Honda-Tech fag, versus how utterly worthless they are in any real application, just sell them. Buy what you really need. Pocket the 1.9 million dollars you've saved.

Re: type R rods in ls block?
 

but you still need to machine the LS rods or the ctr pistons to run them. i agree its the best option though, sell the rods and use the LS crank/rods and shave the small end of the rod to fit the pistons and while your at it have some ARP rod bolts pressed in there too. The LS crank is fine to make power up to 8500. if you want to make power higher than that maybe you might want to look into the GSR crank.

Re: type R rods in ls block?
 

Just get the arp bolts with ls rods. If you still want more insurance then get then shotpeened and polished but by that time your getting close to what a set of eagles would cost. Get gsr lower end internals with the girdle, pump, oilpickup, rods and swap them into your LS block. You'll have to take the a machinist after you install the girdle but it's worth it.
