It's a full leather, sunroof Integra, it's heavy but hopefully she can get it there. I've removed a fair bit of weight from it so far so that will help.

re: PSI GUY's "Another" B20vtec Build Legacy
We got it to the track this weekend, aside from having some ecu and map issues, it was a good first outing to the races. She ended up running a 12.88 @109 second pass then backed it up with a 12.85 @ 109 this morning. She is having a hard time with the 60ft now, couldn't find the sweet spot so the rest of the runs she was spinning. She is pretty confident she can bring it down to 12.5s with some practice and this was full interior on 20" slicks.
Another thing to note, I know he has been banned here but I cannot speak enough praise for Rocket (Rocket Motorsports) in his dealings and help with me and the car. I had a problem with my race map at the track and he figured it out for me and got it running......gotta love technology 5000 miles away. He not only helped fix a problem at the track, but has been a constant help and is only a message away for any question or query I have had. I purchased the M24xx cams from him, and on advise, some injectors and he genuinely seems interested in the car, the dyno and how it performs at the track. Most other companies don't really care, nor can even take the time to answer messages or emails after spending thousands of dollars with them. As far as customer service, during and after the purchase, he is top shelf and comes highly recommended from me.

re: PSI GUY's "Another" B20vtec Build Legacy
Well I suppose I should update this, a lot have changes have gone on since I built the engine and she had been running it for a full season. Decided to try out a VictorX manifold to compare to see if the power up top would pick up and we found some more power for sure.....here is the thread.
https://honda-tech.com/all-motor-nat...ctorx-3226243/
Another big change is we wanted to run the car faster in the class but being a big heavy leather full jam Integra wasn't the best chassis, had the rolling chassis for sale for a while and ended up finding a buyer a week before the last race of the season. I have been looking for an EG shell previous, but nothing decent was around. Lucked out and found one but it was far away, 26 hours later it was home on the trailer.
Car had been a time attack/circuit car for the last 10 years or so, shell was in great shape, just full of dents. Didn't have the best drag suspension but I threw the swap in and tried it out. She drove the car for the first time up the staging lanes and down the track. Didn't get a lot of passes in as it was eliminations but managed a few time trials after and went faster every pass. Best was a 12.16 @ 114mph with a crappy 1.80 60ft. Wrong size tires and gearing ending up putting the car at 8400rpm crossing the line so a gearing change amongst others are needed to dial in the chassis.
Here are a few pics of the car before and after
And one of the timeslips, this was her 4th or 5th pass with the car.
Basically we wanted to get a feel for where the car was at with the swap and what needed to be done.......the verdict, need more gear, more tire and more power.....lol.
Going to get the car set to the rules for the AMS class, going to try to catch a couple of events and she wants to play with the big boys, with some more power and gearing the car should be a good high 11 second street car. Seat time will only help things out.
Now for the changes for this year.
Sending out a block for CSS, going to 85mm and going up to 13.5-14.0 compression and will be running C85 full time. Won't see much street duty but will be driven on the street.
Picked up an AEM V2, some new wheels and 23" slicks, working on a 4.92 Final drive and an MFactory long first gear to help the 60fts. Final drive/23s will put the rpms where they need to be.
Going to get a header built, thinking ASP for an under-car exit but we will see what happens, already sold the old setup.
I'm hoping with the extra compression(JE 11.5 slugs in it now) we can improve on the 247whp, maybe a skunk2 ultra is in order, I'll see how the funds go this winter.
Can't wait to see what she can do with it, might be surprised what happens. Will update once some parts start landing and work progresses.

I am running a 255 walbro with ID725 Injectors, 550s may not be enough for E85, but all depends on the fuel pressure and hp you will make.

re: PSI GUY's "Another" B20vtec Build Legacy
oh ok so walbro pumps are compatable with e85 ? someone told me that i got have a ethanol compatable fuel pump... also i got a 90 teggy should i replace fuel lines?

Well mine has a walbro and I know a lot of other guys who are using walbros with ethanol so I can't see the issue.

re: PSI GUY's "Another" B20vtec Build Legacy
So update for this season, a lot of things have changed and hopefully we can find some more power in the setup. New items are as follows.
85mm Darton sleeved B18C block, LS crank and the same LS BC lightweight rods.
85mm Wiseco K594M85AP, spec'd at 13.36:1
Removed oil squirters, plugged with Golden Eagle plugs
SMSP header, got rid of the Skunk2 one.
VictorX has been ported, huge difference over stock.
Upgraded to an AEM V2 ecu and coil on plug setup.
Head has been milled a couple of times, so has the block so compression should be 13.5-up.
Chassis got some work, all new wheel bearings, brakes, ball joints, bushings, seal kits in the calipers....basically went full retard and spent some money....lol.
Installed some traction bars to keep the wheels in place.
Changed slick size to 23" and final drive to MFactory 4.928 to match ratio to old setup. New V2 wheels
Will post more as things continue, engine is built, cams are degreed and ready to drop in. Tranny is ready, just need to throw it in today and do the wiring for the EPM and COP setup. 15 gallons of C85 are sitting in the shop and will be hitting the dyno this week as long as there is time.
Will post more this week as I get things done, hopefully have some good HD video from the dyno, looking for 265+.

re: PSI GUY's "Another" B20vtec Build Legacy
Awesome build! Let me ask you something, howd you guys like the car with its intial setup making around 235whp, with the b16 non lsd trans?

re: PSI GUY's "Another" B20vtec Build Legacy
Awesome build man! Really nice results!
Are you still trying to find someone to cnc your Victor X? Would really be interested in seeing what improvement could be had. I'm planning on using the same manifold with a slight hand clean-up.
Curious if you or your tuner think that ypur current compression ratio is around optimum for E85? I assume you found MBT before running into any knock/ detonation?
Thanks again for sharing! Great numbers once again! I bet it's a blast to drive!

As far as fuel, I would love to try M5, but would like someone that is familiar with the fuel to tune it. Maybe later on, I'll take a roadtrip and try it out, we are planning on hitting up the IFO race in October in Epping NH, my wife will be racing in the All motor sport class. I figure the car should be a solid 11.80 car, maybe faster so it should be competitive.

re: PSI GUY's "Another" B20vtec Build Legacy
Got the engine in the car today, finished up the wiring for the COP setup and with some basic settings was able to fire it up just for a few seconds to hear it run. Didn't want to **** off the neighbors too much at 11:30pm....lol. Going to dial in the idle and basic fueling, change the oil and get it ready to hit the dyno up this week.

Solid solid setup man. Can't wait to see what it does. I hope to have my car following a similar path once it is no longer a full time daily and I can strip it down and put some good gas in it.

She's a good driver, needs to work on the short track but that will come with time. She only made like 9 or 10 passes in the car in October and went faster every pass so I would assume if we had more time she would have touched the 11's as it was.

re: PSI GUY's "Another" B20vtec Build Legacy
did you dyno today?
Beast of a car...
Did you notice anything different when tuning high Rpm ignition using the new COP setup?
I've always wanted to do a COP conversion.

re: PSI GUY's "Another" B20vtec Build Legacy
Well yesterday did not go well. The car would not make power and we could not figure it out. Tried just about everything and then on one pass it hit the limiter and shut off and would not restart. Checked a pile of stuff and found it seemed like it was out of time and was backfiring and not firing consistently. Decided to take the EPM off and have a look, seemed okay but took it apart and found the screw had come loose inside the wheel for the sensors had come apart. Was able to source another EPM from someone local to get back going and had to redo almost the whole map as the previous one was messed up. After getting the map back dialed in it still wasn't making good power, we tried just about everything, plugs, compression tests, leakdowns, AF rich, lean, timing, changed the rockers as we thought maybe we had a bleed off and a cylinder was losing vtec, etc, etc. Moved the cam gears just about everywhere and it did nothing, I was pretty beat at the end of last night.
This morning I brought a distributor with me and I re-wired the harness for it and we threw a neptune ecu in and it started right up....easier than it ever had with the AEM. We used my map from last year and did a pull, it was lean but made power...finally. Ended up tuning on the neptune timing, fuel and cam gears and got the power up to 256whp and 169tq but could only run 26 degrees of timing, it kept losing power above that so we figured we had hit the limit of the C85 fuel. Drained the tank and put some E98 in, was able to bring the timing up to 30 degrees and made the same power or maybe a bit better, but the graph was nice and smooth so we left it there. After lunch I decided to take the AEM apart and swap the jumpers back to stock and try the AEM with a distributor. We got it going and ended up being able to tune it properly with the distributor up to the same power level so since I paid for the AEM I might as well use it. Must have had issues with the new EPM as well as the old one....nice stuff.
So that's it, 256 whp and 169 wtq, I was expecting more, but I think I've found the limit of something, just not sure what. Going to take it to the track this week to run some passes, it should run 11s without issues, I hope.
I'll upload a couple videos after I get home, we did over 50 passes on the dyno, this thing is tough....lol.
Not sure where to go next with the car, where is the limiting factor is, I figured it would make close to 270 but not even close. Could be the dyno, could be the conditions, mph should tell all next week.

re: PSI GUY's "Another" B20vtec Build Legacy
That's still awesome numbers...
Sounds like you definitely or some work in.
Sucks about the EPM though.
If you get another one that's good or setup some other kind of cam trigger, at least it will be a good comparison between distributor vs. Coil on plug. I haven't seen a direct comparison myself yet.
Good luck finding the bottleneck and finding more power!
Love this car.
