k i normally build turbo hondas. i have built a bunch of na hondas but wit a bunch of stock parts so im not sure on this. my question is i have a 90 integra 4door that i put a gsr head on and i did a obd1 conversion. it goes pretty good right now like i beat the itr in town wit it but i have a stock exhaust n stock ls exhaust mani n air box n i know that there killing it. i should b getting my income tax soon n i am planing on buying a skunk 2 intake mani n a full header back exhaust but i found some throttle bodies on ebay from blox n i was wondering how big i should go. i found them as big as 78mm. now if i went that big would it help me or hurt me. i just don't want to buy something that isn't gonna help or is gonna hurt power. if 78mm is to big what would you guys recommend. thanks

your telling us that you have built turbo cars, but yet don't know if a 78mm throttle body is ok? wtf...anyway, no that i would have to say is overkill, wayyy too big. i'd recommend something like a 68, maybe 70, but no bigger than that.

 

ya have a 398whp 325wtq civic hatch thats my track/muscle car eater lol... ive have built a bunch of na cars but like i said using oem parts like ls/v, b20/v a few b16s n a couple gsr's . Even a few high compression d16 but i never looked into big throttle bodies thats why i was asking b4 i spent money 4 nothing. so a 68mm or a 70mm would work then? ive used skunk 2 intakes b4 but i just used a stock throttle body so i wasnt sure. id like 2 get more opinions no offense but i just like 2 hear wht other people recomend. ill prob end up going wit a 68mm but thatnks

 

I wouldnt get a 68mm on a low compression stock LS with a GSR head? that will lose power lowdown and **** on your gas mileage. you have a 60mm right now. i wouldn't recomment getting anything higher than a 65mm unless you have a big tube header, test pipe and a 2.5" exhaust. otherwise you are wasting money and losing power.
I would recommend an edelbrock 65mm over skunk2

 

well im getting a full 2.5" exhaust wit a hearder n test pipe wit my income tax. my plans are to sell my hatch n wit the money build my lsv n turbo that. i dont really want to get rid of my hatch but ive had it for 6 years n i kinda wanna build somthing new. a guy on craigslist is giving me $7500 at the begining of march for it so thats whan ima start the new build but till then i just want a little more power. so you think a 65mm. this is why i wanted more then 1 opinion. keep the thoughts n opinions comming thanks

 

yeah a 68mm-70mm would be a good choice if you had higher compression pistons in your LS block, but you won't using stock pistons. An ITR TB is only 62or 63mm and they can make 180whp with just bolt ons at that size. so a 65mm would be great for someone looking to make 200+whp. Unless you plan on making over 300, a 68-70mm would be overkill and actually hurt your powerband.
and its with

 

we my original plan b4 i pland on selling my hatch was to put b16 pisions in it to make it high compression and run ITR cams cuz i put a set of those cams in one of my b16's n it made a huge diffrence but now im just gonna buy the same pistions n rods i have in my hatch. im gonna run je pistions n try 2 b around 9:1 compression n eagle h beams n run a gt30 or somthing around that size. like i said i have 398whp in my hatch but thats with a dohc zc n i think thats about as much as im gonna get out of it. i mean its a rocket but i wanna get to around 500whp witch im sure i will b able to do no problem with that setup. but till my hatch sells i just want a little more power. thanks guys for all ur help ill keep you updated on the build

 

and if any1 else has any other input then feel free to let me know. . .thanks again. . .

 

wow i had to read that 3 times just to figure out what you typed.
Your spelling and grammar are horrible.
I would do some more research on what stock sleeves on an LS block can handle even with forged internals. I wouldn't do 9.0 compression either. I would go in the 10.0-10.5 range to turbo. This isn't the old v8 days where poor combustion chambers led to detenation on high compression pistons.

 

well its cuz i was talking to people and typeing at the same time. n i have done my reaserch. ive been buildind high horse power hondas since i was 16 and i grew up building 350's and 454 chevy motors with my dad. ive been working in my dads shop as a mechanic sines i was 15. trust me this isnt my first motor build. i have also been tuning my own cars for about 3 maybe 4 years when ever crome got big. i also street tune alot of peoples cars around here since the closest dyno is like 3 hours away. i know a ls block will handle that power if tuned right and with forged internals. i know for a fact that a d series sleeves will handle beteewn 400 to 450 if tuned right ive seen it a million times do some reading on turbod16.com fi you dont believe me. My hatch has stock sleeves and i have 398whp n thats a d series and ive been running it like that for 3 years the way it is now. n as for the 9:1 compression well with as much boost as im gonna be running and running 93 octain it will b fine. i dont know about you but i cant aford to run on race gas at every fill up so 10:1 is to much for me. im not saying that you cant do it but with stock sleeves i dont want to chance any detonation. but anyway i was just asking about a throttle body so this doesnt even matter. just cuz im kinda new to the site doesnt mean im new to hondas. i just deal with more turbo cars then na thats all. but if you read what i have wrote i have built na hondas but wit oem parts just mixed together.

 

well its hard to read what you write, but honestly just asking the questions you do, you don't seem well informed, but thats the internet. I know that d series sleeves are quite different from LS sleeves in thickness and design and yes i know that d blocks can hold 400hp using vitara pistons on E85 blah blah blah. you seem to be relating old v8 mentality to building honda 4 bangers and honestly they have nothing in common. i highly doubt you can front the money to run race gas on every fill up so don't pretend to ball if you can't. post a pic of your car, lets see this high horsepwer monster

 

i didnt say i can run around in race fuel i said that i dont know about you but i cant aford to fill up on race gas at every fill up thats why im not running 10:1 or 10.5:1 i said i cant aford it thats why im running 93 octain n 9:1 compression. i aint worried about the sleeves i do cylinder posting with 5/16-18 threaded bolts to stop the cylinders from walking and with 9:1 compression it less likely to detonate so it should b fine im not to worried about it. n as for the old school muscle car **** motors no i dont build them anything like that. chevy motors are ancient technology with there center cams wit push rods square ports 2 vaulves per cylinder bluh bluh bluh. i said i grew up bulding them wit my dad since he is old school n is a muscle car guy but then i did some reading on hondas n was sold. i biuld my cars to shut up the muscle car guys around here. idk why you seem to have to proove me wrong. maybe the sleeves will crack on a 500 hp ls but if its tuned right then it will be fine pluss this is gonna be my new track car not my daily driver so its not like im gona be pounding the **** out of it non stop. i have a EG 4door with a gsr swap for a daily driver so it wont be out much anyway. im not saying your wrong or that you dont know what your talking about but from my experience it will b fine.

 

ok, i'm alil confuse too...can you clear it up...so first you wanna go all motor, now you changed to turbo? or you want something fast now and turbo it later? anyways if you're staying all motor then go with an itr tb or 65mm. 68mm and + are too big cuz your compression is not high enough to power them. also get some bigger cams.

plus, theres no point in getting a bigger tb without getting bigger cams or having higher compresssion. it should be the other way around. get bigger cams then bigger IM/tb. but if you get bigger cams then you would need to get aftermarket springs and retainers. gl.

 

that's what i thought but wasn't sure. and ya at first i was planing on just going all motor but i got a good offer on my hatch so im gonna sell it n turbo my integra. the thing is i started this post b4 i got the offer on my hatch. that's why i started out asking about na. like i said i have a daily driver too n i cant go without a turbo car. plus Ive had my hatch for 6 years n i kinda wanna do another build. its gonna b a shame to see my hatch go but its time to do something different. i don't know why that guy thought just cuz i asked about a throttle body that i don't know what im talking about. that's why i asked if it would hurt power or help it cuz i kinda thought it would be over kill to go that big but i was saying that i found them as big as 78mm and i wasn't sure what you guys would recommend. i figured that something a little bigger might help a little but like i said i was just saying that i found them that big that's all. well thanks for at least trying to understand what i was asking instead of just automatically assuming that i don't know what im talking about or what im doing. i just have a little trouble explaining things when im typing. sorry. but ill post up some pics of my hatch and my other rides since some people don't seem to believe me thanks again.

 

 

and b4 anyone asks what the dents in the hood are from a while back my clutch exploded n took out my bell housing to my tranny, my radiator,and dented my hood bad day at the track

 

and this is gonna be my new project once the guy pays me for the hatch. its kinda a shitty pic and its really not a looker yet but give it time it will be



and this is after i lowered it when i first got it

 

the teg motor

 

and the 4door its been sitting for a while. these are old pics but it will be back out soon

 

oh and on the integra i know the head lights are gay but they were in it when i got it im gonna try n find jdm one peaces but if i cant find any ill at least put stock ones in it

 

no replyes now?????
