Any of you guys running LS rods in your D16's? I tried searching through the archives and the All-Motor forum but only came up with people saying it's possible but not whats needed . I know you have to get some material removed for the wrist pin to work, but thats about it. Any specific info or specs would be awesome.

 

Well after a little further investigation I can confirm the rods are the same length,
D16/D17 - D15Z1/B connecting rod length: 137 mm
B18A/B - B20A/Z connecting rod length: 137mm
The only thing I need to find out is about the base of the connect rod that sits on the crank. I know the LS rods are wider but will be a problem?

 

LS rods are the same length as the D16 rods (137mm) - the LS uses a 21mm diameter piston pin where the D16 uses a 19mm diameter pin - to use LS rods with OEM D16 pistons, you would need a bushing for the pin - the crank end of the LS rod is wider than the D16 rod - in order to use the LS rod in the D16, you need to mill 0.022" from each side of the rod on the crankshaft end in order for them to fit the D16 crank

 

, finally some help. Any idea as to what or where I can get bushings for the wrist pin's?

 

You need custom made aluminum-bronze bushing with a width of 0.786, ID. 0.748, OD. 0.827 +(over) three thousands due to the bushing will be pressed in the small-end of the LS rods, so the bushing won't come out of the hole. Crower did sell these for around $40 a set - don't know if they still do

Vitara pistons and 98-00 Civic GX PDN-A00 pistons use a 21mm pin which makes the LS rods a good choice when using either piston

please note that he was setting the bushings up for full floating pins

Great info man , thanks for all the help. There is some good info in here maybe it should find it's way into the FAQ's

 

wat are the bennifits of running these rods is it worth the trouble to make them fit i would like too know thanks guys

 

Ya i got a set modified for d16 before. I got crower to rebush the small end to fit a D16 wristpin and the sides of the rod where it connects to crank I had milled down so the width of the rod on the big end was the same as a D16. Install ARP rodbolts and recondition rods and you are good to go

 

There is also a piston that will fit the LS rod, it's out of a D series Natural GasD16B5. Higher compression too.(The B18A/B Rod has the same bearing bore as a D16. It is 0.044" wider, so the sides of the "big end" of the rod have to be shaved down for use in a D16/17. The wrist pin bore is larger so a conventional D15/16/17 piston can only be used if the stock "small end" bushing in the rod is replaced with one of the proper size. These affordable rods are generally considered to be able to handle up to 300 hp (220 kW). (The wrist pin bore in the 98-00 D16B5 is 21 mm, like the B18B rod.)Found in:
1998-2000 Honda Civic GX
Displacement : 1590 cm³
Bore and Stroke : 75 mm X 90 mm
Rod Length : 137 mm
Compression : 12.5:1
Combustion Chamber Volume : 32.8 cc per cylinder
Valvetrain : SOHC VTEC-E
Fuel Control : OBD-2 MPFI
ECU Code: PDN-A02
I almost went this way myself,just going to turbo instead.

 

is it worth going through all that trouble?does make a lot more tork or high end power?

 

not sure if your being sarcastic or not but changing rods will not make power(ok they might if they were lighter or something buy not sure if it would be enough of a difference to measure)
the reason they do this is cause the ls rods are stronger then the d16 rods they can TAKE more power, not MAKE more power.

 

I heard they will handle close to 300hp.

 

take a look at the 500 page ls-turbo thread and you'll see a handful of people running 300+ whp with the stock ls rods. now whether or not the d-series block can handle the same abuse i dunno :-p

 

but wouldnt it be easery just to get eagle rods or somthing like that?

 

i started to do this until a good friend offered me a deal i couldnt pass up. in the long run if your just building a d series to run 10-15 lbs of boost on and make a good reliable dd, yes this is a great alternative. i have 75 mm vitara pistons that im selling. i actually have much much more than that as well.

 

thats a great idea!!! who ever figures that out saved me like 400$. My gfs dad is a machinist so ill just go there and get him to show me how to do all this!!!! awesome just gotta find me some ls rods now!!!

 

i just had another thought since you guys seem vary well informed!!! Wat if i bored my d16 block out to a 1.8 litre could i use a bseries piston if so which one?

 

You serious?

 

you would not be able to bore it out that far without sleeving it. and if you had to do that, then there's really no reason to use stock pistons since the point of sleeving is to give you teh ability to run gobs of boost.

 

ya sry wasnt thinkin straight there guys...got over excited!!!! has anyone had any issue with using the ls rods?
