I just swapped in my new LS/Vtec I got from Viren. It is Darton Sleeved, Endyn 9:1 pistons, eagle rods, Jg Pro Series Head.

Now it is making a funny sound when I started it up. It does NOT sound like a Honda. It sounds sort of like a diesel truck, even when fully warmed up and has a completely different tone...which is a deeper, LOUD tone compared to my stock GSR motor. I have heard piston slap on a motor before with forged pistons, but this one sounds different in a weird way. Is this because the rings are not seated?

I have adjusted the valves to spec and am currently doing the breakin procedure at idle. I cannot drive the car since I bought a messed up tranny. I have been keeping the revs varying up to 3000 RPM for 15 minutes/oilchange and another 30 minutes/oilchange.

What is this that I am worried about? Thanks.

 

DOn't worry about it. My friends build d16 sounds weird now that its built with a cam. You're going to hear all kinds of weird noises that aren't their now that you've done serious work to your car.

Why don't you get a tranny asap so that you can put a load on the engine to seat the rings? Sitting and varying the rpm's is no way to help the rings bite.

 

yea i want to get another or fixed tranny asap.

 

i had eagle rods and srp pistons in my old LS motor , it was not very quiet , sounded a little different .

 

yup, mine sounds like a minibus too...but I think its kinda cool...once it breaks in itll sound like a Honda again---so I'm told.

 

haha ok. I actually kind of like the sound.......but did not know if its normal. Thanks
