Default Jay2415's Turbo LSVTEC EG Coupe

What's up HT?!
This project came about as I was really bored and started looking through Craigslist and saw this 93 coupe in semi decent shape, with a knocking B20v for a couple hundred bucks. I thought, why not EGs are becoming rare in the north east nowadays.
So I Decided to pick it up.
So that night I thought long and hard, I've owned about 9 civics and they were all fun....but really slow. So then I decided I'm going to build a 500hp, quick spooling, street car. First order of business was figuring out the knock, after a few turns. I could tell there was something going on in the block. Like a spun bearing. So I decided to hunt for a B18a/b block and scrap the b20. Picked this unmolested b18a1 block off of a running DA that had to be junked because of rust. At this point I knew I had to make my dollars stretch as far as possible (4month old daughter, and just bought a house)...the costs were gonna add up with the turbo kit, Ecu, engine work..I managed to scavenge a custom kit suitable for my goals, but decided to not buy the turbo from the seller, it was way too big for my needs. I ultimately Decided to send the b18a block to CNC Werx for CSS, jetwash, deck, bore and hone to 81.5mm. Paired the block up with wiseco 9:1 forged pistons, Eagle H beam rods. Soon after I started the b20v removal. Turns out the b16 head, has a port and polish, Crower springs and retainers, Type R cams. ARP head studs, AEM fuel rail with aem regulator. Skunk2 intake manifold, not sure what throttle body..doesn't look stock. Everything in mint shape. I think the previous owner had no idea what he was selling for as a whole for $700 Clutch turned out ok too, I believe it's an ACT w/ act pressure plate. Unknown Aftermarket lightweight flywheel. Definitely buying a new sprung 6 puck clutch. Not sure if I should buy the whole package. After a lot of reading and research on available turbos, I decided to go with the journal bearing Turbonetics T-GA 6157 t3 .65A/R from go autoworks. It was the ultimate decision based on budget, reliability, and it should perfectly meet my goals. Now I'm patiently waiting to get the block back from CNC WERX. While I stockpile parts and figure out a full build list. Also I have this crappy engine bay to deal with.

Precision Intercooler "rated 800hp"
BWR top mount turbo manifold
Tial 44mm wastegate
Tial BoV not sure which
custom 3" piping

Woot woot. Nice body and clean collection of parts.

i ran that turbo for two years, loving it. I still have it packed in storage. I then switched to the tga 5857 turbo when it came out. I have dyno comparisons up in my build thread. Late last summer i made 496whp (dynojet) on a 81.5 b16. So you should be able to on the tga 6157 and an lsvtec build with similar parts. Not sure of new yorks elevation with may also play a part.

just so you know 500whp is alot to deal with handling wise. Aswell as general maintence.

i also did the comparison videos of a 2.75" vs 3" exhaust. It was skunk2 70mm vs 76mm. .........The 70mm was louder lol. Same when we did the comparison on the 8th kraftwerk si.

How did you you like the 5857 vs 6157? I'm actually pretty confident I can make 450 easy. I'd be totally satisfied then.

Like you said, 500hp is no walk in the park for a street car. I come from a 2015 WRX that was putting down 350hp to all four, fun car but it started having issues here and there all the time... It's easier to have your $700 civic give you issues vs the $27k car your still paying for do it. This is gonna be a grocery getter, I'm actually gonna trade the wheels for stock ones, to keep a low profile.

I'm gonna scour your threads to check it out.

If you want it to be a street car, try to up your piston compression a little. Why take the best part out of hondas? That's high compression.

my thought was to keep it low enough to drive like a normal car, and avoid detonation. I could run 9.6+ but it's a higher risk. The 3% of the driving time I need it to have higher compression, doesn't outweigh the other 97% of the time I'll be driving the car.

9.5 -> 10:1 is 100% safe assuming you have at least 91 octane available.

3" exhaust for sure.

I do like what the 5857 brought to the table and how the setup is as of now. However, there has been a few changes since i last ran the 6157. Would like to see how it responds and reacts now after all the newer mods, but coughing up 500 dollars for a refresh isnt worth it. Not to mention, setting up BBG again. That **** was a pain. **** took all summer literally.

if you trust your tuner, i definitely agree to go with a lil higher compression. More compression will enhance every aspect of the motor setup.

also, after doing the switch from 70mm to the 76mm catback, i definitely recommend a 3" exhaust. My personal discription of what will happen.... itll wake the turbo up sooner, make more power, and be quieter. Quieter by getting rid of the resonance from the smaller piping.

and dont forget to add an intake to that setup

agreed, the plan is also to run e85 almost exclusively with an ethanol content sensor, in case I ever need to drop in 93. And in my experience, this is a must because of all the shitty gas available here in the northeast.

I'm 100% decided on doing a 3" exhaust now lol, I think I might pick up the skunk2 rr, and add an extra resonator in place of the cat.

intake is definitely gonna be added. Just want to assemble the motor, and drop it in to mock everything up and see what kind of space im working with to add one neatly.

I actually ordered the Kteller 3" exhaust, with 14" resonator and magnaflow muffler. Decent price, fit my budget, and many people on HT use their exhausts. Will probably still add an additional resonator in place of the cat. I just can't deal with load exhausts anymore...maybe I'm too old

I've been studying the need for the boost options on the s300 v3. Obviously the biggest pros, are being able to control boost pressure through the ecu, and boost by gear. Now I've been reading on boost by gear l, but don't really see how a good tuner cant tune the car to drive normally to the same effects of boost by gear at low speeds, around town driving. Also ls joker you mentioned it took all summer to get right, why is that?

Couldnt agree more on the exhaust im changing mine this weekend cant stand 3" skunk2 catback with Megapower

Boost by gear does not need to be "tuned" on the dyno make sure you get tuned to your max boost lvl at the dyno. Some tuners will setup BBG on the dyno but they can tune BBG all day on the dyno and it means nothing. The street is completely different. Alot of times you will hit boost cut once you hit the streets as street build boost bettter then the dyno due to increased loads. As far as low speeds arround town you dont have to be in boost 24/7 part throttle will not create boost really especially with the setup you have. BBG is moreso for full throttle situations, and setting a max boost per gear not the minimum

BBG can be a bitch......... no 2 roads are the same so once you think you have it dialed in you realize this and works well only when you have perfect traction, there are also variances with temperature. You really need to spend some time with it until you figure out what works best with your setup

pretty much all of this. My summer was spent chasing down inconsistancies. Thats prolly the least concerning thing at the moment. Besides after all your work is done, if you did go the BBG route, dialing it in is the fun part. Dont let alittle work change your mind. To the point where youll just get a hallman.

Lol people tried to convince me to go Hallman I didn' like the fact that you still will need oem ecu anyway if you plan to keep oem cluster, and the harness needed is the same cost as a full Hondata ecu

Nothing wrong with a Hallman for those in a budget project car or simply to avoid issues with the ECU.
So, for reference, I would have tried to convince you, too..

hmm.. Never thought about it that way. I went Haltech and didn't want the OEM cluster anyway. But didn't think of them as requirements. I got a Harness to fit my Haltech for about $450. About the same as a new Harness from Rywire.

Sure they do just don' want full boost in 1sr or second gear or trying to control boost with my right foot. Maybe in the future ill try that method but for now ill stick with my bbg

What hallman did that?, you don't make enough exhaust energy to get full pressure on 1st gear any way. And if you don't know how to control your own throttle, then you shouldn't be driving a car, my friend

So today I made a 5 minute attempt on cleaning the garage, and noticed something I didn't before. The transmission isn't a b16 as I thought. I think it's an early UsDM ITR tranny with the 4.4 final drive and LSD. This is a huge plus if that's what it is. But really I just hope it's a good working tranny.








CNC Werx, just finished the work on the block, should have it by Tuesday. tomorrow I'll start cleaning up the engine bay, and adding the gauges, etc. I already ordered everything i thought I was missing except for the s300. I plan on picking one up myself from xenocron, so I can also speak to them about tuning the car when it's done as well.

That's not what I stated, and you know that.. Please Don't create an argument like that, then attempt to bait me (or my rank) as the object of your being offended as a deflection tactic. You're a good dude. Don't drink that kind of kool-aid and resort to that. It goes nowhere.

IMHO, and it's just that, an opinion from my perspective, is that you've appeared to have made the assertion that "full boost" (regarding target boost pressure) on a given setup (I.e. 9psi) would be reached using a standard manual boost control, like a Hallman, in 1st gear, implying as though BBG is the only thing to use for control, (and that everything used before, and hence, is ridiculous to use, obsolete, and anyone not using it is crazy.)

I'm simply saying that isn't the case, and it sounds rather exaggerated. Target boost can't be reached in such a low gear. There's not enough exhaust energy to do that, and control has been, and continues to be made consistently using your foot, and your brain with a manual one, when practiced like anything else when driving the car with major changes... Still great tools.(foot & brain)

What you stated, although understandable regarding your setup for what you're using for your purpose, is just an inaccurate statement. Nothing more , nothing less, nothing personal, or personally invested.

Yesterday I received the block from CNC Werx. I am extremely happy with the outcome. They bored the cylinders to 81.5mm, honed, added the CSS, decked the block. They also jetwashed it. The jetwash results are ahh so so. I've sent worst to machine shops with better outcomes. But nothing some brake cleaner, a rag and high temp paint can't fix.





I was gonna start checking clearances tonight but ran into a problem with my bathroom sink...got frustrated and ended up yanking the whole thing out. So thats another project for tomorrow....installing a new one. I also still have parts rolling in, as well as some I need to pick up that a buddy is donating to me from a previous build.

Also took advantage of the good weather earlier this week to scrub, and attempt to clean up the engine bay. This thing needs work. The inner me, wants to get it painted properly, the dumb me wants to get a rattle can and spray bomb it, the actual me decided to just clean it and leave as it. This isn't going to be a show car. Just going to repair the surface rust with a wire brush, primer and black paint. The surface rust is mainly on brackets etc. Also fully removed the PS lines and reservoir. They were left in the bay without the pump by the previous owner, so they were all damaged. Used the same lines to loop the lines on the steering rack.

Sunday morning update:

Yesterday I had enough time to file my piston ring gaps, as well as double check my bearing clearances with plastiguage, then assemble the rotating assembly.





Main bearing clearances were spot on, the rod bearing clearances I expected to and were on the looser side. Still within spec though.





Overall happy with how its turned out so far.





Earlier in the day I helped a buddy of mine pull a blown s2k engine (what a headache). He also contributed to the build, with some spare parts he had laying around. Used billet avid mounts (the ones I have are mismatched), Toda Oil pump gear, a few other odds and ends. He also sold me some rare Eg seats with matching door panels. Not exactly sure what they're from. He believes its from a rare anniversary edition. Only issue with this is that my interior is grey, so using these means ill have to source the rest of the black interior trim pieces including a dash.
