hey...i'm the new guy. i should start by saying i don't personally own a honda or acura and my knowledge of these cars is nill, but i'm here because my cousins has an integra and i might be helping him to build up the motor. i personally am a domestic guy, but def have an appreciation for the sport compacts. used to have an old 86 prelude si and it was one of the best running cars i ever had, rust and all!
anyways.... here's the deal. i'm not sure what year his integra is, i think it's a 97. he was talking about selling it, but he has put alot of time and money into the car and it's pretty hot. its got a kit on it and the interior is custom and there are some engine mods, which i have to find out a little more about.
he says it has type r pistons and i know it has a computer control device mounted on the dash which controls air and fuel and v-tec and does all kinds of stuff.
now the questions.

1) lets assume it has type r pistons. they came in the car when he bought it. what else might be done to the car? if i were to go through the trouble of putting new pistons in, i would be sure to spend some extra money and get some other things done, but i'm not familiar with the honda engines, so i don't know what would be a standard procedure. what else might the previous owner had done while going with the type r pistons? also...what makes the type r piston differant?

2) what do we have to do to make this thing fast? it's quick now. it pulls pretty hard, but there is always room for improvment. turbo would be nice, but i'm not sure he is going to have the $$$ to really do what needs to be done to the bottom end to make it bullet proof enough to run boost. forged internals and what else?

3) does anyone know a good place to get a head/cams package?

4) what kind of power can you get out of these cars going all motor? i think he has a b18...c?? he's got a header and cat back, type r pistons, the computer thingy on the dash, and who knows what else. i'm pretty sure it isn't cammed. it idles too smooth. what should we add, upgrade, and/or replace while doing a rebuild?

thanks!
:-)

 

you say that you don't think he'll have the money to make the bottom end bullet proof enough to run boost, but running an all motor set up would require that more than running boost! Every year they push the envelope of stock internals w/ boost i know several people running over 300hp on stock sleeves and internals, now granted good tuning is necessary to do so. To answer one of your questions type-r pistons run a higher compression than other pistons, i can't remember exact figures but i know it's higher than 10:1 cuz that's what a gsr runs... but anyways the higher compression allows for an increase in horsepower, so i would also look for possibly the head being built up...

but a better way to help you would be to find out what motor is in it? (B18B, B18C1(GSR), B18C5(Type-R) this helps to determine a better strategy for the build)

 

Hey man,
Welcome to the wonderful world of Hondas...
It's nice to see that although u enjoy domestic cars, u realize that Honda's are incredibly reliable and can be made quick pretty easily.
First off, you're comment "it can't be cammed, it idles too smoothly" is remarkable, considering what VTEC is, because that is exactly what it was designed to do...
In your buddies DOHC VTEC motor, he has two-seperate cam lobes, which turn on for the different engine load conditions.
DOHC VTEC, is like having 2 different cams in your car at the same time, because one is optimized for low-rpm and the other is optimized for high-rpm.
the high-rpm cam, if it was to stay "on" at idle, would indeed have a "lumpy" idle, because it is exactly the same as having a high-rpm cam in a V8 domestic...
Most people (domestic guys) don't really understand the operation of it, they just HATE on it, cause it really does work, and it makes them when they lose to a 4 cylinder...
It's called technology, something that, unfortunately, domestic car makers have turned away from, instead choosing to build out-dated designs, such as pushrod engines.
I'll update some more when I get a chance,
Later

 

https://www.honda-acura.net/forums/s...highlight=vtec this was a verry informational post made by VTEC-Power alot of great info on here...

 

his funds will be limited and i think he could do either a turbo or supercharger on a stock bottom end, or build up the bottom end and go all motor, but not both. i'd rather see him build up a stong bottom end and get some quality components and down the road he could always make some changes and add on a turbo or super charger without worry of if the engine can take it.
i don't know what kind of numbers these cars make running stock, but i'm guessing he's about 185 at the crank with mods.
he has a 94 integra with a b18c1 ( gsr ) engine which came out of a 96.
what would it take to get into the mid to high 200+hp and what would it cost? what is a good source of info on building the motor and whats a good source for getting parts at a good price? whats the most power than can be squeezed out of this engine on an all motor set up? i don't know if 300+ is realistic without boost and on a budget. what will $3000 get us?

 

$3000 can go all for parts, i'd be doing the labor.

 

I dont THINK 3k is gonna get you over 300+ N/A but, with 3K i would suggest doin a turbo kit. From what i have read superchargers on a 4 banger is not all that great i have an b18b1 (ls) and i have a drag turbo kit. i paid right around 2k for it and that was everything, but it was used. If you guys decide to go with a turbo though i would suggest a better clutch than oem. I have had my turbo kit on my car for prob 7 or 8 months now and the only problems i have had are a broken axle and my clutch went out. Oh ya as of now my whole long block is factory internals and i dont even have any type of fuel upgrades such as injectors or fuel pump and im running about 8 psi as a daily driver... i love it

 

how do the stock internals hold up running boost? what about stock internals with type r pistons? i got an lt1 z28 camaro and we generally don't like boost on stock internals, but i know it's a whole differant animal.
what kind of power are you putting to the ground with the turbo on a stock motor?

 

well i know that you are going to want low compression and i know that the type r pistons have a higher comp. sooo i would suggest trying to maybe find some low comp. pistons sense you are doin the work that shouldnt cost that much and you should still have enough for a turbo kit. One thing though dont go cheap with turbo stuff, you can try ebay i know i have gotten some stuff off there but go with name brands...

 

yeah whatever you do, if you hit up ebay stay away from ss auto chrome, their products sux donkey balls. Most of the time the turbo manifold cracks or even breaks... so be smart on putting together a kit, wether you build your own or buy one...

stock internals hold up well with boost as long as you don't go over board, for example if he needs major reliability, I wouldn't push past what most kits run at(usually around 8psi) because most premade kits are designed with a stock motor in mind...
