It’s cool that he has his pops on tour with him, while shouting out his son. 🤘🏾

Wow! How’d you manage that little one-on-one session? Does your boy realise how lucky he is? What I would have given for tips from a drummer of Art’s caliber when your son’s age. What a cool Dad you are man!
man I wish he knew, but one day he will realize. thanks for the support!!
I remember you from the old B15 community. Do you still have your spec v?
I do, just drive it on occasion, but it lives:)
@@WRPTechnology I'd like to see it in a new video.
He's my Dad ☺️☺️☺️
Does the engine run sloppy and out of balance with the balance shaft removed? Or hollowed out?
No the engine runs fine with the Balance Shafts removed
Thank you for the refresher. Now I'm confident I didn't miss a single step. I am curious as to why you used a ball hone instead of flat stone hone ? I would think to reduce tapper u would use flats but.....
Ball hone is better for even honing imo, but I could be wrong. That engine turned out great though :)
Remove that engine...Put on engine stand
I was broke at the time, and was rebuilding it in the car. Engine came out fine!
i have a few questions !!
What's up?
How would I go about the head gaskets for torque
Taper is usually at its greatest at the top of ring travel because that's right at where most of engine wear happens - right when the fuel & air mixture goes bang !!!! That's why the ring gap measurement is done at the bottom which is the most unworn part of the cylinder. I've had no trouble running stock 70,000 kilometre old RB25DE pistons in a 300,000 kilometre RB30 engine block, they are a tough motor & the new rings were a tight fit in the cylinders. The engine has done 200,000 kilometres since the build & is still good. I have another RB30 engine block & I'm unsure of how many kilometres its done,all I know is that I put 230,000 kilometres on it in 5 years & we bought the car with 227,000 kilometres on the odometer, but the pink writing on the valve cover told me it wasn't the original engine. It has a maximum of 0.117mm of piston to bore clearance so needs 0.020" oversized pistons & a rebore. Maybe it's done close to 1,000,000 kilometres.
Did you have to remove the crankshaft ?
No, we never removed the crank when we did this semi rebuild
where is part 5?
I'm doing the same to my Altima 2003 qr25 and I have some questions 1: is it qr25 the same as qr25de? 2. What brand of brand of main bearings and piston rings would you suggest me? What type of oil should I put once For the first start up? Thank you sir!
1. yes it's the same engine 2. factory bearings are fine, order from your local dealership 3. amsoil break in oil is what i suggest.
sir thank you! i'm sorry to bother, i am having big troubles checking my cylinder bore. could you make a video of how to use the bore gauge. thank you
I have a Nissan Altima 03 and I'm about to rebuild it but to be honest I'm scared because of the measurements! Some questions sir! Where can I find the spec of the engine? Could you please tell me where can I get them. You made a really great video thank you! Hope to see thousands of videos more from you!
Where's part five. This was helping me so much.
it's in my brain :-) email me wperdigon@live.com for any help.
What grit flex hone did u use.and was it the silicate carbide or the aluminum type
Hey William. Did you have any more video's after Part 4? I'm getting ready to rebuild my Mom's Altima 2.5 and find these vid's very informative. Thanks
William, where is part 5, I have a Nissan Altima this is a great video series !!!
This guy seems knowledgeable, too bad he's generally despised in the Nissan community. And 2j racing already made well over 200whp+, but with a bit more than a piston swap.
Will, you briefly mentioned the balance shafts. What I need to know is if these are removed is there a oil hole that would need plugged? Thanks,BR
great video..,. getting ready to install my turbo kit and i need to put a new set of pistons, rings, and rods, in before i throw the turbo in. Im burning about a quart every 300 miles now. it was every 600 about 4 months ago. so this video was a great example thanks for the info. if u could PM me with any other info that would be great. compression test came back good.
Thanks, let me know if there is anything I can help you with =)
These engines like blowing head gaskets, stupid open deck design with the pistons squeezed together so close like that leaves little material to stay in place. Luckily I never blew mine and got 180,000 hard driven KM out of the thing before I wrecked the car lol, also one thing you gotta do with this motor is delete the pre-cat because it likes to break up and get sucked into the engine. Never burnt a drop of oil!
Flex-hones are already over sized for the application you order for. A 3.5 inch hone is slightly oversize to accommodate that size cylinder, so your 3.75 is over-sized as well, and too big for that cylinder. Flex-hone also recommends 10-30w motor oil as a lubricant, WD-40 is too light. I'm not trying to be de-grading or anything, but why did you use the size you did and the WD-40? The information above is literally on the side of that box you had.
Do u have the video when u took the head out..
This is the unreliable "Renault" that's hidden in every Nissan now. No more Nissans for me.
I have a 04 spec v and I just bought 07 spec v pistons rings rods and I wanted to kno what rod bearings to use
you should upload a vid of that sqr you got...
love this comment!
I did finish the car and it does run. I will talk about what. I soon
Ask any question you want
i have sooooo many questions
I've just subscribed, good job sir.
did u finish the car?did u dyno the car?
The me pistons I am sure are great, however for improved performance, the qr20 pistons makes the qr25 13.1 compression. Significantly better then
je pistons 10:8.1 the best i. got then...makes a huge diferents when u step on the gas
William thank you for the awesome videos on the qr25 rebuild. i am in the midlle of doing one right now, i have a few questions to ask you if that is ok. 954 266 9299 Armando.
Yes they sealed without any problems
they are slightly different sensor wise, don't quote me, but I believe the Crank Trigger Wheel is different as well....It's always best when dropping a motor in to replace it with the same one your replacing
could i just order a long block from 2007 and put it in my 2002 are they diff
so the block is the same throughout the years with everything else changing
yay for making up horsepower claims without any variance! Engineering at its finest here.
bwahahahahahahah
ha, true story
great video while i study for my a1 recert thanks!
Good job awsome u gotta finshed the video !!!!
YES!!! Technical terminological. Long Live the Car Nerds
Thank you very much for the kind words. I try to be informative when possible in a way that people have an ability to know nothing yet understand everything when it's all done. I will be show casing a new build we are completing next spring. So keep an eye out for out next build =) Thanks, William Perdigon
I've rebuilt probably 4 engines and this is the best video that I have seen by far!! The proper terminology is being used, it's very descriptive, and Mr. Perdigon explains the process in way that most everyone can understand. He even explains the tools being used and why. Excellent video!!! I would like to see the pistons being installed. Thank you, Brian
TRUE!
Atv more atv lol
