yea most hondas are slow, but then you always gotta watch out for the unexpected fast ones cuz you never know lol. this one was surpricely quick and i didnt know until i ran him. not even k20swap civics are worth a good race unless its boosted.

Also 60s shouldn't be more then 80% on that s20g on 26lbs if it is your to rich. i ran a 6758efr at 27lbs with idcs of 76% with 60s and another efr 6758 at 22lbs with 60s and his idc was I think 65-67% .. so I'm sure you will be fine. With it being turboed have your Tuner command a rich mid range to say around 11.5 and ramp it to 12.3 ..... .

i have a s20g and i cant push more than 23psi. anymore and im knocking, plus im only on 15* of timing so i could be wrong but doubt he can push 26psi on just 93 pump.

really? most dsm's push regular 20g's past 25psi consistently. This turbo doesn't even really wake up until you hit 25psi. On e or an eblend, you should def try to ramp it to 28 or 30psi and really watch the show

Just wondering because we are on this topic. how much psi do you think an lsj can handle before the head comes off the block on stock head studs?

Also sense i am talking about cranking up boost here, how much boost would be too much for the s252et?

as far as i know, at WOT i see 12.1-12.3 and it drops quick to the 11s then goes down to 10.0 by 6500rmps all the way to 7200rpms

exactly i feel the car loosing power from just how much fuel the injectors are dumping in up top. but thats what my tuner couldnt fix because apparently either my injectors arent 60s or theres something wrong with them.

How did he tune it on the dyno or street? Mine was reading that first until on the dyno they found out there was being to much air from the compressor.

jonathan, if you want, i can ask my tuner to look at your tune. Gonna need a list of your mods though, unless everything you have is still the hahn lvl 5. There's no reason you should be at 10:1 afr at any point in your tune.

John have Ure Tuner send the tune to me at cali_motocrosser@yahoo.com ill look at the tune and also send a log so if I need to revise it. And he can push the turbo to 25-26 no issues. If your getting kr look into your tune or into your fuel.

With 60s, maybe his tuner scaled them incorrectly or if he's boosting more then the boundaries within the ecm he needs to tune it via pe tables and get the ve table down.. so its either or. I don't see the injectors as a whole to be the issue.

no prob. But if I were you, before you think about upping the boost, I would get rid of that internal wastegate and see you can get an external. You run less of a risk of boost spiking that way, especially if you want to see higher than 24psi.
