shit looks horrible
Its not clay is ussually aluminum with iron sleeves (most imports anyways).
CRY I am currently building a motor believe me I know what you are talking about, I post frequently at hondatech, and to be honest its full of morons. Theres a few guys that know their shit though. You can run boost on an CR its all in the tune. The better the tuner the more you can push the envelope.

i dont know but i see a 10:1 CR with high boost as being disaster. high compression engine and high boost can be done, but its on a built engine. id rather put some 9:1 CR pistons with eagle rods and ls sleeves to be able to turn the boost past 20psi. an ITR engine cant go past 10 psi otherwise itll blow. im not denying the engines ability to make that much hp, however i have a hard time seeing how an engine thats high compression with a turbo will last long, or wont be strained. i have a kid at my school who used to own a civic with a gsr turbo'd. the thing put down 560whp. but the engine was fully built. tuning helps, but even ls engines when turbo'd can only take so much boost.
I agree. I remember when I was younger, most people who had the B18C5s and wanted to turbo it usually had to swap out pistons and lower the overall compression ratio. If I remember correctly, the stock compression ratio for that engine was 11.0:1, which is pretty high.
By the way, one of my co-workers is planning on buying a '98 Civic CX hatchback. I think he wants to buy an Integra LS motor, then eventually do the LS-VTEC conversion, then eventually strap on a turbo. It should be a quick little car.

Tunning doesn't help, TUNING IS EVERYTHING. Without a proper tune (dyno'd then tweaked on the street) even a built motor will blow. People run 300hp ALL DAY on bone stock LS and GSR motors. Most people who don't know much don't even run an engine management program (ie. Hondata, crome pro, uberdata, neptune) they just trick the stock map sensor and get a FMU which is horribly unreliable. CR does mean something, but even a semi compotent tuner can tune a car with 11:1 without it having any detnation issues. I agree that lowering the CR and sleeving the block will allow you to run almost unlimited boost (most I have seen was 36lbs and that was limited by the 3bar mapsensor) but stock bseries engines can take boost all day with the right tune.
EDIT: re-read your post... why would you put LS sleeves in a GSR block? I'd spend the 1200 and get darton sleeves installed at a machine shop and have them bore and hone them. LS sleeves would be pointless, alot of work for minimal security.
is this guy fucking around with the belt on his supercharger??

so i got bored and decided to look for videos.... i googled something calleda boosted eg hatch...atleast, thats what i cut and pasted from somewhere else....dunno if thats the full or correct name...found this..

duke, i found out what that dude did with the GTO.... it says that pontiac has this thing where you can rev the car from under the hood....that's what it said...sorry if i sounded retarded...
also, how much boost can an engine take?? 16psi? normal turbos give about 6-8 right?? could 20 just blow your car up?

the del sol, s2000, the yellow eg hatch, and the nsx were nice :thumb:
the sound the gto was making sound like the intake. he was revving it from the throttle body. whenever you press on the gas, the wire pulls that part that he was playing around with (throttle) so it revs it up.
on the boost, what engine are you talking about?

It's hard to say how much boost an engine can take. Some engines, specifically ones already with large turbos, were made to handle a lot of boost, while other engines weren't. You just have to look at various factors, like engine size, turbo size, compression ratio, stock setup, etc.
Stock turbo setups allow a good amount of boost. Most Evos run a lot of boost completely stock, peaking at 19 psi in the Evo VIIIs and 20.2 psi in the IXs (which is pretty crazy, seeing how it already has a compression ratio of around 9.0:1). I don't remember exactly, but I think stock WRXs would run about 13.5 psi and the STi runs 14.5 psi. And usually when you begin modding, boost can safely be cranked up a psi or two before requiring more serious mods to strengthen the engine.
Now onto cars not boosted from the factory. A decent amount of people end up strapping turbos onto their Hondas and what not. Most people who do that usually use the older Civic Si motor (B16A) or the Integra GS-R motor (B18C1). Since those motors are smaller and have slightly higher compression ratios, they weren't really made to handle boost, so most aftermarket turbo kits made for those cars usually put out between 6-8 psi to keep things safe. Anything beyond that can blow the motor, unless you strengthen it, and that process usually requires the engine to be opened up. However, it can lead to the bulletproofing of the motor, seeing how there are a lot of built motors running 20+ psi, even a handful running 30+. But usually at that point, it's not really meant for daily driving and probably won't pass smog tests.

i remeber someone stating earlier that supras were bulletproof...so ar e we looking at 50 psi outta this?? or would more work need to be put into it?
is it also possible to have a supercharger and a twin turbo in a car?? each with maxed out, or close to, psi....around 20 each, so 60?? or would the car blow up?? i heard these were inefficient..
