Ok, so I have a 96 integra ls coupe. My b18a1 went about 2 months ago when the oil light started flashing, and started rod knocking. I took it to my local honda performance shop. He told me my bearings where shot, so i told him i wanted to get a new motor, we decided on the b20b full swap. So he ordered me a b20b motor from - NIPPON MOTORS INC. in Cali. I live in PA so the engine took about 2-3 weeks for delivery. He got the motor and installed it. Took it for a test drive and the oil light was flashing, he checked the oil pressure and it was only getting 2 psi at idle. so he was pissed and called the place, they said the were going to next day a new motor (b20) so the next day sure enough he got the motor, he opened the valve cover and looked inside and said it was clean. Nippon Motors claimed the new motor they sent had just 38k miles on it. so he did the install and hooked everything up. took it for test drive and did oil pressure check and it was running great. I picked my car up the next day and drove maybe 60 miles on it, not even taking it past 6k rpms. i stoped at a light and the oil light started flashing for low oil pressure. so i called the performance shop and they told me to check the sensors. I checked them and the light was still on. I was pissed so i drove my car all the way back to the performance shop. with the oil light flashing the entire way - which was about 25-30 miles away. Once i got there the car was starting to stall and squeak a little, like a belt squeak, pretty sure it was the bearings going, and next. the owner of the shop took my car for a ride and romping on it and holding rpms @ 5500rpms it finally gave out. starting knocking badly. so the 3rd motor now died from oil starvation.

Now here is my question... Has anyone had bad luck or heard bad things about NIPPON MOTORS? I thought they were a good JDM motor source?

Also I just keep thinking something is wrong with my car for the oil starvation to keep happening, it cant be an electrical problem can it? Is it just that possible to get 2 new dirty bad motors in a row? Everything oil is mechanical and comes on the new motors? How does this happen 3 times?

By the way we just ordered a new b20 from H-Motors-Online... so hopefully 3rd times a charm. I am just ready to drive this car off a cliff.

PLEASE LET ME KNOW WHAT YOU THINK AND WHAT MAY BE CAUSING THIS OIL STARVATION KILLER. ( Bad Motors? / Electical Problem? / MY ****IN LUCK? ) Thanks !!!!

i would have raged. maby its happening for a reason. '' final destination '' sorry just got done watching that movie but yeah it could be possible. hopefully 3rd ones the charm.

Naz04ryan

haha thanks, yea ive had the car over a year and last summer ran perfect with the b18 and i put her away for winter and started her back up this spring with the oil light flashin and ever since ive had no luck. Its a beautiful teggy tho would hate to get rid of her. Im lookin to boost the b20 but first i need to get her stable with the new damn motor running great... im starting to doubt. Hopefully Hmotorsonline is better than nippon. I dont know

JayR408

oh your getting a new motore from hmotorsonline? nice .. just curiose but what kinda oil are you useing? synthetic ?

Fern413

wow thats crazy....lol i think is jus your luck...but hopefully everything turns out to be fine with your third swap man g/l

Naz04ryan

Thanks guys i think i need the luck, i used synthetic in my b18, but i believe he just put in fresh reg. 5w30 oil. It is a well known Honda/Acura Performance shop in the northeast. He has done hundreds of swaps and keeps saying hes never had this problem. I'm installing a 3 gauge pod for - Oil Pressure/Oil Temp/ & Boost... Ill kno exactly if im getting oil pressure + im lookin to boost in the fall. But im not sure why this is happening. The motor was full of oil and the oil was very clean 60 miles after the swap and the oil light was flashing, we both thought it was the sensor, but sure enough it wasnt, it it blew up. Im just so glad i didnt do the swap myself. I would b screwed...


** HAS ANYONE DEALT WITH NIPPON MOTORS or H-MOTORS ONLINE??? **
- Not sure if this has happened to anyone else on here ???

JayR408

oh if your doing i new swap i would recommend a magnetic oil drain plug because of the excess shavings

dude, whatever the claims of mileage are, the real mileage is TMU (true mileage unknown). all these motors come from junk yards basically and they just tell you its low mileage so you buy it. (i sell to them) hmotors i believe is one of my buyers but they do so undercover (i sell to anyone by mail if they contact me....wholesale customers go to the warehouse) they are the picky buyers i have so thats why i believe its them. and theyre only like 20 miles from my wholesale warehouse. but they ask the mileage and i tell em TMU. but i have seen some of the low mileage motors and installed them for people who bought them and brought them in. i did with no guarantee or warranty. a few had rod knocks. and one i know came from my warehouse. my wholesale motors are meant to be rebuilt and are not sold as a used engine replacement. my rebuilt motors are sold as good motors and come with warranty but not the wholesale ones. that many bad motors makes me wonder about the shop you go to though. personally, i would have rebuilt the B18. hope the third one is the charm.

JayR408

what he said no company can know what mileage the motore has thats why ther gonna tell you 50k. note 50k 000 the zeros not 50,875 ect

Naz04ryan

ok, thanks guys. I didnt kno much about buying used motors. I know honda is known for good motors, but this has got me thinking>? I used to be into DSM's... I had a 99' eclipse gst and i rebuilt my 46g3 motor with forged pistons/rods and everything and i got it back and it blew up on the dyno. I think its just my damn luck with cars and motors. My cars look great but why cant they run great. I baby the hell out of them too! O well, I hope i get a good motor this time.

RICKSAUTOMOTIVE

if the same guy built the eclipse motor for you as this guy working on your car now, i would stop going to him. it might not be your luck but your mechanic who isnt doing things correctly. by the way, how did the motor blow up? i recently did a head gasket for a guy on his 95 eclipse AWD turbo model and he did everything correctly. new head bolts, new lifters, a complete valve job, oem gasket and timing belt, etc. torquing the head bolts on that eclipse is not like a regular procedure. you torque the bolts to a certain spec in a 2 step sequence...then you loosen the bolts then you torque again to a specific spec...then you go around torquing in the normal patern but you torque simply by turning the head bolts 90-degrees tighter on each bolt....then the third and final torque step is to again turn each head bolt in the torquing patern of the bolts another 90-degrees. i had never done a head gasket on ne of these eclipses but i found out that that is a crucial issue when torquing the head bolts on that car. if your eclipse motor was like this also it may have been your mechanic that didnt do this. i would try another shop. you may just have better luck with your car. if this motor blows up again with another shop working on it-then its your bad luck. hell at this point you have nothing to lose by trying another shop. the other shop may look under the hood and wonder WTF??? if they see some strange mechanic work under there from the shop you visit now. good luck with the car again. trying the new shop is just my opinion on what i would do if i were you

Naz04ryan

Rick, its not the same mechanic. The place i go to now is on the east coast in PA. Its called : Absolute Proformance - They Specialize in Honda / Acura - The mechanic worked at Honda for 15+ years. Hes legit, he has done tons of swaps and tons of sick hondas. He even has a Turbo B20 Integra & B20 Turbo Del Sol. Im not counting him out, he has been really nice and apologetic. I just spent all this money and i want a reliable car. I hope this 3rd motor is a good one. Im tired of having my car in the shop especially with summer on the rise. Thanks for all your input. Also as for my Eclipse i had, it was more of the Tuning shops fault than my Mechanic i used to go to. My mechanic didnt wanna fix what they blew up. It was years ago and one hell of a learning experience. Thats when i switched to hondas and i had 2 civics, never had problems and now just trying to find a good motor for my integra. Shouldnt be this hard. WTF... haha

Naz04ryan

Bump... Anyone Else Have New Motor Issues from NIPPON MOTORS or H-MOTORS???

f3joel

I bought a b20 from hmotors and it blew up in less than a 1,000 miles.
I have nothing good to say about them.

Naz04ryan

were you reving it past 7k rpms? haha, rev limit is 6200... you dont gain anything past 6 with the stock motor. thats why im turboing it, seting hondata rev limit at 6,200 rpms so i dont blow it up

nafreak

this got me thinking, is it possible for the motor to be set down to hard on the oil pan and close up the gap between the pickup and the pan? Thus the pickup not be able to "pickup" any oil.....

RICKSAUTOMOTIVE

well i assume it is possible. have you seen some of these guys transporting engines and just drop them off a pick-up truck bed onto a styrafome block which absorbs the impact? true story LOL. i dont use those guys anymore for shipping engines to my customers. but i couldnt believe they did that till i seen them do it myself LOL

my friend bought a jdm b18c from hmotors and it ran fine for about 2 years until he sold the car, status is unknown now, but... when he got the motor vtec didn't work for the first few months, his tps sensor that came with the swap was shot and iab didn't work.

turboskratch

Most of these companies that stockpile and sell these motors source them from Japan. So between the mileage/km conversion, the condition of the engine when it was pulled out, the fact that it's very likely pulled out of a car that's been crashed, and the shipment and handling of these motors in the containers overseas, it's truly a gamble no matter how reputable the company is.

What oil filter(s) were used? Oil problems like that on multiple motors leads me to believe that it is a batch of bad filters that are clogging and not allowing oil to pass through them. Unlikely yes, but more likely then 3 bad engines in a row. If you/the shop didnt replace the filters with new ones each time and reused it, then that is all on you anyway.

RICKSAUTOMOTIVE

since someone brought up the oil filter issue i'll add this...although i think its unlikely....
a small amount of honda acura customers reported their oil lights coming on indicating an oil change being due. the sensor is tripped by low oil pressure. if the filter reaches its maximum capacity to filter, the level of restriction from the dirty oil filter slowing oil passage/cycling can become significant enough to trigger the oil pressure warning light. in extreme situations, oil starvation can occur. premature oil filter capacity can be attributed to a number of factors such as poor air filtration, a leaking air intake system, or excessive contaminants being produced in the combustion process.
these are just a few things to consider along with a poor quality oil filter.

If this question was for me.
I was running a stock LS computer/redline.

You're about the 5th person I've heard about in about 2 months that has had problems with them. I don't have personal experience with them but I had a customer go through them for a motor..Installed it for him, and about 2 weeks later the car was coming back in via tow spun bearings and all via Oil depravation.

Honestly I deal with Engine Depot or for a little extra I'll suggest a customer opt to have their motor rebuilt when they buy from places like these for extra assurance (I usually cover the crank servicing charges myself and just make them pay for Bearings, Seals and Labor). I dunno man, sucks to hear someone is having so much trouble motor after motor....tell you what, if you're having problems still and you need a motor, I have an LS Swap here, 3 angle valve job and a Ported and Polished head, I'll let it go to you for 400, entire swap, u cover shipping.

Good luck man!
