mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
My build thread is in the CRX portion but thought for anyone looking heres my current results. I was not chasing power but i wanted an overall OEMish reliable safe fun car i can drive.
plugs gapped at .030 and running 93 octane on 13-14lbs of boost.
Go Autoworks X600 Kit w/ GT2871r
Cam gears were set at +3 exhaust and +1 intake, that were i degreed them at and during the session we just left them as he said it was making power easily.
Overall issue was as we increased boost the exhaust housing on the turbo was running out of steam on the top end but yet midrange picked up more power. He started with tuning just the lowcam tables and did some pulls there then went into drivability etc. Some folks have questioned that the dyno doesnt have enough load. i CANNOT answer that, what i do know is once we hit the street he did minimal tweaking and the car feels/pulls GREAT!
re: mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
Whats up man. Ive seen your car on gregs facebook page a couple times. Very clean. Just dint know the build specs. I believe the cam choice you went with is creating a backpressure issue due to turbo sizing, and the turbine housing size. Unless you have a .85ar turbine housing on. If you did have the .63ar housing or vband variant, changing to a bigger turbine housing would free up the topend some. Some say youll lose spool, but i didnt notice a difference other than the topend.
whats your bore again lol. A 75.5mm b series? I like the setup and the cams. I just think you should change the tur ine housing out if you plan on keeping those cams in there. There will be people who will tell you that those tuner2 cams dont work out for boost setups. But ive seen plenty of times where rock on free flowing turbo setups.
p.s. does skunk2 mention running oem LMAs for those tuner2 cams. Or their brand recommended.
re: mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
I have the .63ar, very possible. Man I’m dumb no idea why I typed 75.5 lol, edited now. They didn’t say I had to
rub there LMA’s but they were on sale I think when I bought the other parts so just said meh let’s roll with them

After swapping back to the OEM tach i think i like the "look" of this more. For whatever reason the Omni tach in higher RPM's all of a sudden was having a spaz like my ignitor or the dizzy was going bad. It was fine until boosted. The S300 datalog looks smooth and the oem tach does not do it but heres the Omni tach doing a similar pull.

Update:
I was installing the hondata Cpr kit and while the car was idling i had noticed the oring on the bov was not seated. I removed the bov and seated the oring then proceeded for a little drive down the road. immediately pulling out of my garage I noticed the bov actuated much earlier in the rpm and was louder. got to the end of the block and gave her some gas and the car felt wildly faster. grabbed the laptop and did a datalog. beforehand i made 10psi @ 4600rpms but not i made 15psi @ 4660. I was ecstatic and decided to do some of my own tweaking but running off just wastegate pressure it was holding 12lbs now as opposed to the 10 it did on the dyno. Because the fuel map was all different now with boost coming in earlier i decided to run around without the boost controller until i could get her retuned. It now clicked in my bed that this was probably the culprit why it wasn't responding well up top giving the boost controller more duty. before it would hit 14.5psi but fall down to like 13.7 and hold it. give the solenoid more and it just wouldn't do anything. well now leaving the duty at 50% it built 15psi super early in the rpm range versus falling from 14.5 way up top. I was for sure thinking I would make like 400wheel easily now and honestly I believe i would have. I really want to autox this car so i decided to remove that spring and put a smaller one in which now on the street held 7.8-8psi. I now have traction in 2nd gear as before with wastegate at 12psi I did not. Changing the spring now shot me in the foot because with my 3port it now makes 17 ish and holds steady at 16.5. With that bigger wastegate spring, it definitely helped spool. So new results now are laid over the other chart. Basically 2ish lb of boost more and it holds better without the leak. We messed with the quickspool within the s300 on the street and it seemed to work quite well but during shifts it would have a hiccup so for now, that's turned off. For now, I'm staying here, so hopefully, I can autox running off just 8lb wastegate.

Do you know what gear your tuner has the car in while he’s running it ? Sounds like it’s in 3rd when as far as I know boosted cars should be dynoed in 4th. Clean car love the color and the layout out of the build.

Good question.. I do the majority of my WOT street tuning in both, 3rd and 4th. I experimented a little with 2nd gear as well, this was a bit more difficult on the street though. Lol.

Pretty sure he jumps between 3rd and 4th then we went onto some nice open roads. did mainly 3rd gear pulls and then some 3rd into 4th pulls. He said all was well still, it did load up a little bit with the quickspool enabled and hit boost cut which is at 18lbs. the biggest issue on the street after lowering the quickspool was keeping it enabled and me shifting from say 2nd to 3rd. it like stuttered real bad. i also shift with enough time to bake a damn pizza so not sure if that caused it to spaz.

absolutely. now if given the formula 1lb = 10whp I could probably hit 400whp going up to 19-20lbs of boost BUT I would either need a 4 port or go back to the old wastegate spring :/ doing that though I have no traction in 2nd and with this being driven mainly on the street I like to hit the pedal whenever I want and it goes. soooooo probably will reside here for a bit and try to fight off the boost bug :D

Has your tunner not try to go into timing retard by gear and pull timing out in first and second gear til you have traction. It’s a big thing single turbo v8 drag cars do. Leave the line with 20-30 psi and have no timing in it and ramp the timing into it because you timing can move faster then you can spool the turbo

we actually never discussed it. i do get the idea but we never did no
Re: mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
Well try that. I’d try pulling 6 degrees in first and 4 degrees in second and see how your traction is then. But if your on small tires like a 185 or 195 or cheap tires then there’s not much your gona beable to to do.
Re: mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
After reading some on it, it seems that’s more focused towards a drag setup, not sure how that would do with just daily driving. Wondering if hondata traction control would be worth it. Granted it wouldn’t be cheap and I’d have to do some fab work since I don’t have ABS
Re: mynameisjustin and here is my CRX B18C1 GT2871R Build Thread
Yes it’s from drag racing because the whole limit in a drag race is how much power you can put down at that momet during that section of track or road. It wouldn’t be any different then “daily” driving if your daily driving your not gona be wide open and hitting boost anyways. Well use it or don’t up to you
