ok so i got this friend of a friend who claims his 2dr civic is running 24 psi. now in my limited knowledge to make a 4cyl handle that much pressure one would have to shell out a lot of money. if im not mistaken drag racing 4cyl use at or around that much boost if they use it am i right? not street cars with 4cyl engines.
basically i tried to tell the guy he was dumb but hes not interested in listening to me and remains firm on his claim. here is what i told him.
1) the engine would have to be at least 2liters either bored out to that or like that to begin with.
2)have to have massive modifications to the block, head, crank, axles, transmission and the turbo kit itself.
3)a t3/t4 turbo that most kits come with arent capable of 24 psi i dunno if thats tru or not.
4) if one was to want to do this with a 4banger it would have to be a DOHC preferrably with VTEC.
5) hes a dumbass and should read and learn before making stupid statements.
if any of this info is wrong i apologize ahead of time but i was curious whetehr or not im right. is it possible to make a 4banger use 24psi and would it cost well over 20k parts and labor etc, or is this kid full of shit. ps - he also claims soem of his friends have other cars running this much boost but refuses to tell me what cars tehy are. any help would be appreciated.

yes, the block defeatnally would have to have been re-sleeved. At least. also some sort of management like Hondata, AEM ems, MoTec, etc etc. (not a piggy back). also a 3 bar map sensor would have to be used instead of the stock one. Yes, defeatnally clutch has to have been upgraded big time. the t3-to4e would be capable of hitting up to like 30 psi actually before it starts loosing its efficiency. It will boost more, but wont be any good. This turbo comes with the fmax kit ( I know the prelude fmax kit has it). all other t3/t4 are defeatnally capable of hitting 25 psi. No doubt. my friend has a 20g on his tallon running 17 psi all day long, has had it for like 4 years. and still ok, never been rebuilt or anything. He also runs 20 psi at the track no problem, and this turbo is noticebly way smaller then my t3/to4e (t3/t4). and his still internally wastegated and no boost creep or anything.
I really don't think that kid has an idea of what he is talking about either. Just ask him what turbo he has and what the trim is, like 60 compressor with a 57 trim wheel. and a 63 exhaust housing with a stage 3 wheel--------those are the numbers for my turbo, The compressor is the cold side of the turbo, 57 is what the wheel measures. 63 is the size of the hot side of the turbo housing, stage 3 is the wheel in that housing, there is stage 1,2,3, and I think up to 5. thats a t3/to4e. There is turbos that are t3/to4b which just has a bit smaller housings, like 57 housing with a 57 trim wheel, there is also 48, 50, 52 size housing for the hot side also. See there is so many different sizes to experiment with. Thats why turbos are better then superchargers, because u can't change superchargers wheels or housings and stuff. If he is really running 20 or over in boost, he will defeatnally know what turbo he is running.... also, ask him what kind of wastegate he is using and size, what fuel management he is running(like fuel pump, computer, injectors, or combination of all), if he doesn't know, then he doesn't know crap, period.
it's possible but is costly. My friend's neon r/t pushes 28 on some super 16g from hahn racecraft or something like that. The size of it is amazing. He bought the kit from a guy that was in superstreet or a magazine like that with a green neon that was running mid 10's with nitrous and slicks.
Then again, his motor is a bullet-proof race prepped 2.2l crate motor. He runs stand alone fuel management. And he's gotta use some super high octane fuel for the thing. His axles could probably withstand a herd of elephants and his clutch engagement is more harsh than a drunk biker gang.
The car is hardly streetable, yet he tells me he'll drive it occasionally anyway .
Too bad him and his old lady broke up and she won't let him back on the property to get the car or anything. He says he's got a huge plan to get it back though.

Sorry this is a little o/t but Hahn is from my state and only about 20 or so minutes from me. The 420a's and 4g63 kits and products those guys release are unbelivable!

it's been know to happen. i wouldn't neccesarily call him a liar. 24lbs isn't the same for every turbo. he could be runnin 24lbs on a really small t3. i remember i believe it was "stoopid" who boosted 20 or so lbs on an Ls for a while.
but to answer your other question..
1. No, i know stock bore b16 making 400+hp
2. it can be done on stock head, axels, tranny. Not recommended since the clutch wont last.
3. it can be done, but it would have to be sized just right.
thanks a bunch. i figure ill find out this way. race him with my car(92 gsr with new b17a1) with basic bolt ons and if he doesnt beat me by a considerable length then hes full of it. lol. jk. thanks guys.

why not tell him to take you for a ride. Tell him you havenever been in a turbo car before and want to know what it feels like, then tell him to floor it and see where his boost gauge goes to?:eek

just a thought, you shouldn't talk shit about people for doing the same thing you're doing (ie. you told him a bunch of false information before researching it, then you came here and and asked if you were right)
i think you owe this guy an apology, and he owes you a ride!

not to be mean or anything, but you might want to know what your talking about before you start running your mouth. But i know what you mean about a kid that talks crap all day long, I got one in my town. This kid told me he has a NOS tank thats the size of his whole back seat. hahahahah
Personally, I think you are both idiots. Why would you tell someone something and not know for sure about what you are saying that makes you just as ignorant. The things you say are almost as bad as what he said. Why in the hell would you have to use a 2.0 or larger to run 24psi of boost. You could run 20psi + boost on a built 1.5 with a smaller sized turbo and wouldn't have even 5g in the motor and turbo setup. I personally would never say something to someone unless I knew what I was saying was the truth, if he wants to be stupid and lie or whatever let that be his ignorance, you made yourself just as bad when you spoke.

And why in the hell would you have to use dohc or vtec. The only reason people run big boost on B series or (vtec, the way you describe it) is because for the most part there are more available quality parts, thats the only reason.

I have heard a lot of the race car out there, don't even have vtec. They are vtec motor, but they have the vtec lobe the same lift as the reg lobe. they do this cause their power band is all set to their where is needs to be and they are never in the other power band.
