build up of JDM F20B DOHC VTEC

Damn you and your awsome gear-ratios! My civic needs a lude transmission.

eh i think they are kinda long. i finish the quarter at the very top of third, like 8300rpm in 3rd. what the civic needs is a B tranny

[F22HB]

No way,lol. Not after all the work to make the f-engine and transmission fit. Not about to redo the mounts/axles for that. Nice times starting out though. Everytime you go they'll get better. Everytime I go to a testntune I get like 2 or 3 runs in, idk if its the same for you..

ok, well then stick a h22 tranny in there with lsd woot! ya, i only get about 5 runs in each time i go. kinda sucks, but eh, what can you do.
my goal for next track day is 14.2 or better. gonna try and get my sixty footer down to around a 2.2 flat

With good tires and lsd, shoot for a 2.0.

I always thought my car feels slower at the track than it does on the street. Why? your Iat sensor gets heat soaked, and your ecu pulls timing as a result. If you can find a way to keep the intake manifold cool, your times would get better. I notice mine rising mostly when the hood is closed. with the hood open, it doesn't get nearly as heat soaked. These test were done sitting in my driveway idling. just my

I just dont see my driving skills netting a 2.0 sixty footer. At least not yet. ima keep my street tires on and just keep trying to improve

my car gets completely cool. there is about a 30-60 minute wait between runs. heat soaking is not an issue.

I would love to go to a testntune and get in 5 runs. I think I have like 6 passes total with the civic. non turbo and turbo.

lol im usally the only slow car in the test and tune lane. I always get lined up with 10 and 11 second muscle cars.

what was your best time with your civic btw?

[F22HB]

14.2 with some warped exaust valves and a blown turbo . It was interesting. That was my first run just rollin it off the line and I got a 14.2. That seemed kinda slow and the next two runs I made almost perfect reaction times and shifts and launched it as well as I could ended up being like 14.5 then the third run was 14.8,lol. It was getting pretty bad. On the trip home it was running sooo bad. Warped/bend exaust valves arn't too good on performance. I knew somthing was wrong on the way up there though. The car just didn't like it had the response it had before.

[fatboy1185]

so, both my front and rear motor mounts are OEM solid filled, yet my motor still moves, quite a bit too.

The intake manifold will heat soak even with the engine off, you would be surprised to see just how long it takes for the im to cool off. Last time I went to the track I got around 100 degree intake temp on the way there and 135-140 when I launched because of how much it heat soaked while sitting still. I let the car sit with the hood open for about an hour and it only dropped to about 120. I have a bisimoto IM heat shield and the coolant lines bypassed. I am not completely sure but I think that timing is pulled with intake temps around this level.

Very cool car, it is pretty impressive in the video.

thanks man, not really doing anything with it now, just daily driving it

I also wanted to ask...
Why did you decide to go with the Skunk2 intake manifold?

Euro R manifold or stock manifold with a Blacktrax spacer under the IAB plate seem to be better options.

According to a number of dyno results I've seen online, Skunk2 intake maifolds seem to perform worse than the stock manifold (on H22s)
