Icon3 My LS VTEC Motor Build

Hey everyone. I made a thread about my whole build on teamintegra, though I might share it on here as well. I started this build back in December and have been working on it since then. It was a slow build, but also my first so it was cautious and making sure EVERYTHING was in order and spec. I received a lot of help from both teamintegra and honda-tech with this build.

Here is what I started with



I bought this one year ago, my junior year of highschool with 115k miles. The car looked like this



I was just learning stick and how to work on cars and it even took me about 3 hours just to do a cold air intake. The resonator box was a bitch though hah



I lowered the car and painted some meshies and the car went through all this







https://honda-tech.com/forums/showthread.php?t=2565893



I did little work but figured an LS VTEC Build would be a fun thing to do. Got a B16 Head from a reputable shop.



I also bought a b16 block from a friend and almost went straight b16, thank god I didn't



I started a build in my room and decided to take the P30 Pistons out of my b16 block and use them in my ls vtec build, only to have them chipped from a machine shop getting them taking off the rods



I ended up getting brand new p30's. Much better anyways

I got the motor out after 2 nights worth of work on a friday and saturday night with a friend



Here is the head off of the LS



I was learning while I was going but was starting to get the hang of everything

Here are the pistons out from the LS Block



Also picked up a b16 y1 transmission instead of using the ls again



My mounts were still in good condition but I really wanted a little bit more stiffness in them and was on a budget so I improvised and made my own polyurethane mounts using my old ones



And here is the block stripped down









Honed the cylinders for the new rings and pistons



Then I had my LS Rods Shotpeened and equipped with ARP Rod Bolts
Whole Rotating assembly balanced and crank pulley shaved because it was chipped









I also rebuilt my transmission because the bearings were bad. I owe a lot of it to all the guys in the transmission section. You were all really helpful and had quick responses and I appreciate that!





Here is what the shot peened rods look like compared to the crankshaft



Cleaned out





The finished product came out to be this





Today I started it for the first time and it started right up! One time I tried but the dzzy slid but I tightened it down and it started like nothing.

Here is the video of the start up

I got scared when the rpm dropped from the vacuum and you'll see me jump lol

I'd like to thank anyone who has helped or supported me in the build. My friend Ryan (ryanevansoh on honda-tech) helped out a lot and gave a lot of support and other friends as well. This was the first time I ever rebuilt a motor by myself and I was looking for more power and to show that I was capable of tackling such a big project. In one month, it'll be a year since I bought my car and knew almost nothing about cars or even what the inside of an engine looked like.

My car has come a long way and once it is tuned in June, it will be a happy one year anniversary.

Thanks for looking at my build thread. I didn't want to go too much into detail but this is a skim of all the work done. The winter went by so fast doing almost nothing but research and engine work. At first I said I wish I would have waited, but now I feel as if it were worth it.

I am thoroughly impressed with the work that you have done. You documented all the work, pics are great, and you did this without any training. That is really quite impressive. Most people would never attempt this. I really liked the shot of you knocking out pistons from the block while it was sitting on the floor. I have never been there, but I have done similar things when there is nothing else you can do. Brings back many memories of my Fiat days. They sucked. After my Honda days started, I have been loving it.

So this is a testiment to Honda and to you where Honda made it simpler to work on, and you had the guts to try something that a handful of people would try, and most of them have had training.

Very Cool. You will be an asset to the Honda Community!

Wow, I appreciate the support a lot! Yeah, the build started a little rough when the garage was full and I also didn't have an engine stand to use so my bedroom was the only option lol.

You are right though, Honda did make these motors so that they can be built easily and be reliable. Now that I have done it once, the second time would fly by if I had all the parts already and a motor to work on.

I felt like I had a lot of guts but halfway through the build even though everything was going so smooth, I was wondering how in the first place I went through with it all lol.

Thanks again man, I appreciate it!

Thanks man! I know what you mean. I will do that today though for a few quick trips around the neighborhood.

because p30s > pr4s and the pistons from that b16 block were damaged when the machine shop was trying to remove them from the b16 rods.

Nice man! I am breaking it in myself, so I won't be getting it tuned and dynoed until I have a few hundred miles on. How much did yours make?

Thanks! I will post them up once the numbers are in

Nope, they didn't because they said they thought I knew that their machine to press pistons off turned them oval and I wouldn't have been able to re use them anyways. I was a little irritated at first but I guess having to buy new parts will boost the reliability up more

Read this link then consider going ahead a getting it tuned sooner.

Source: https://honda-tech.com/forums/showthread.php?t=878397

I got mine tuned within the first 100mi of the initial startup. Ringseal happens pretty quickly after startup on a freshly built motor so the breaking in process tends to be contriversial due to here say mostly.

The most important thing is running with a correct tune, otherwise it can lead to other issues.

Heres my current setup, nothing spectacular but fun for DD paired with an ITR tranny none the less. Just a budget build.

B18A1 (81.25mm) ~12.1:1 C/R
PR3 head stock (milled)
P30's OS
Stock rods w/ARP 8mm bolts, resized & balanced
B16 obd0 cams (sucky I know)
P30 manifold/stock LS airbox
LS TB
98 spec ITR header
2.36" EX
New oilpump/water pump/bearings/etc

wow, I am glad you showed that to me. I gotta drive it a couple of miles since I yet have tested my transmission but after that, I will definitely tow it to seattle/tacoma for a tune. I appreciate it! Our specs are really close, and we even are both using b16/b17 cams. I couldn't really afford cams or and upgraded valve train so I built the block so I wouldn't have to pull the motor again.
Hopefully sometime next year I'll have the head built. My numbers will probably be close to yours

Your crossover looks like a good slope though!

Yeah my tuner had VTEC set to engage @5600 part throttle, and 4400 more than 50% throttle. My block had been decked slightly and the head was milled + I used my oem cam gears since my tuner said adjustables probably wont do me any good until I bought aftermarket cams any how.

My cam timing was installed advanced about ~2+ IN & EX, but all in all Im pretty happy with it for now. Later I would like to do a 3angle VJ, get a Performer X manifold, SK2 or SMSP header, Sk2 Pro1's or Stg 2's, and 2.75" EX "IF" I decide to put any more money into it as a NA motor, or just simply rebuild it from the bottom up again for boost.

Goodluck with it! Shoot me a PM when you get it dialed in or post it in the ALL Motor dynothread. I'd like to see just how close they are too.

Nice, I'm in the middle of rebuilding up my LS/VTEC. I need few more misc parts. I can finally put the motor back togather. I'm bumping up the compression close to 12:6.
