Im having a hard time finding the header for a t3/t4 for my h23.
what is the max boost on the cylinders, i know they are crap to start with, and
is there a 6 speed that will bolt up?

 

a six speed wont bolt up, you should be able to finda manifold, and i have a full 3" exhaust system and a 3" single tipped stealth muffler that I could sell you for that setup that could work nicely. My advice is think twice before you start buying parts.. I did, but then I got into college in CA...

you prolly didnt find anything because a turbo doesnt bolt on to a header......

max tolerance the cylinder can hold depends on the power output, not the psi. HP/psi varies per turbo.

no.

6 speed what? 6speed tranny? Why would you want a 6 speed tranny for a boosted application?

 

header, manafold its the same ****. im try'n to stay on pump gas. 8lbs puts me at 111 octane. i want to drop compresson to getr more boost.

 

i run out of gears. im hitting 5th in the qt. itsd geared low.

?????

let me get some of whatever you are on...

when you are searching 9/10 you wont find turbo information when you are searching for something like a "header"

 

there are plenty of guys running 12 psi + with 91 pump. what rpm are you shifting at the be in 5 in the quarter. i just get into 4th near the finish.

 

im not ebay'n the parts what i can find it outragus in price, coming from japan

 

love fab makes manifolds or you could get a log manifold from drag or even get a dsm manifold and mod it to fit there are plenty of options

 

manifold here


http://cgi.ebay.com/ebaymotors...ZWDVW


its a log one.. importpowerhouse has a sidewinder tubular manifold... other fab places can make you one

What transmission do you have now? Aftermarket gearset? It's unusual to run out of gearing, especially with an H23. What rpm are you shifting at?

What are you talking about?

Read the Prelude FAQs.

 

where did this 8 psi = 111 octane?

you don't add the psi and octane level of the gas...

ive seen people with over 400whp on pump gas on h22s. get a good tuner and you can run 93 octane and 12 ish psi

 

12 psi only? I am running 18 on 93 octane and drive it everyday. A good tuner will tell you not to go over 20 on pump gas but I wouldnt boost over 10 on stock internals.

yes 12 on a properly sized turbo is plently, the BSFC of a boosted H is different than most other boosted hondas, we can't run as much boost on pump as other honda motors.

what size turbo are you runing?

 

Why cant we run as much boost on Pump gas as other motors? Because I know a guy here who is running 18-19psi daily on 91ocatne in his gsr. What makes a B different then a H? Besides the H is larger, there should be no difference. Again it doesnt matter about PSI its HP. I would say one you start poking around the 500whp mark you close to not pump gas.

H22 piston ringlands are the weak point. In order to run forged pistons, you need to resleeve or run Mahle gold pistons, etc etc etc....

 

Again, just something to think about. Different sized turbos set to x amout of psi will vary.
T51R at 10 lbs is alot more than a 14b at 10 lbs.

 

Yes I understand that, I am gonna resleeve my block. But the way the other guy worded it was that we cant run as much boost as other honda motors, which is complete bs imo.

 

You guys are valuing pressure way too much. 18psi and 8psi from different turbos could very well flow the same amount of air. Instead of comparing how many psi one guy is running compared to the next, you need to compare how much power is made with how much timing. That is the critical number, which eventually determines how long stock pistons will last.

it is a airesearch t3/t4, model ta0301 twin spool. its supost to be at full boost at 2200. whats the most the stock cylinder wall will take?

 

your safe around 275-300 I think on all OEM internals.

its just engine geometry, B series engines need less fuel to make the same horsepower that an H series does. it all has to do with brake specfic fuel consumption, but i think this is getting outside the OP's thread, look up BSFC if you want to know more.

 

I'll be waiting for the "i blew my motor" thread in a few weeks... You need to do a lot more research.

Many of these posts are just people saying what they heard from someone else... almost all of the information is incorrect.... power has nothing to do with how long something will last, the reason B-series motors can handle more boost in the stock form is due to the overall design and efficiency of that motor. The "H" motors are a different design, and unfortunately less efficient. I don't feel like correcting everyones thread, but the fact is that the H-series motor cannot take as much boost as the b-series motor "out of the box".... Hence the reason most people turbo their b-series motors, they want to avoid the expense of re-sleeving to get a reliable powerful setup.
