Tell me what you guys think anything i am missing?????

Ditch the air/fuel ratio meter.

Get an EGT gauge instead!!
Exhaust??
Does it already have a BOV and Wastegate??

I am hoping that the(BOV), (WG) will come with the engine?? As for exahust custom with test pipe and muffler.

a turbo timer is a nice thing to have

Do NOT go to FastGo for the Downpipe. I along with many other SE-R folks have not heard good things about their quality.

If you want really good, go to Jannetty Racing. It's a little bit more but you'll get your money's worth.

If you want a little cheaper measure out what bends you need for the downpipe, buy the mandrel bends from JCWhitney or Summit and and have J &M Exhuast Specialists in Manchester fabricate you a downpipe.


You'll also need a place to mount the guages. Get some lotek guage pods .

I'm in the process of Turboing my SE-R. Good luck with your project.

yeah get an egt guage and get a greddy one too because from what I hear autometer's egt has a long probe and isnt as accurate.

wastegate on those engines is attached to the sidemount intercooler.

are you smoking crack? or did you mean the blow off/ recirulation valve????

david lau

im looking at the picture of the sidemount right now and it looks like the wastegate is sitting right there next to it, but that is the recirculating valve. but yes, i am smoking crack.

Hey Stirpicult, can you explain to me how you could possibly think a wastegate could go on your intercooler piping? Do you know what a wastegate does? I'm really tired of people posting answers to questions just because they think they know the answer because they read it somewhere.

hey, no clue. i corrected myself. big fucking deal. and i didnt mean attached to the intercooler. wastegates regulate boost dont they? this is the first thing i have ever posted that has been wrong. i fixed it. i shouldnt have posted. why don't you teach me instead of jumping in my shit? wastegate is next to the turbo. i know this and i dont know why i posted. but feel free to keep bitching.

I just dont want this board turning into a typical honda forum. I see so much bullshit flying around on forums like superhonda and honda-acura.net, it's sickening. People believe all these myths as truths and keep reaffirming these myths by continually posting them. Newbies read it and a new generation of car enthusiasts believe these myths. I am just so glad there are so many guru's on this forum with tons of experience and knowledge dealing with our cars. We are truly lucky to have them as a resource. Stirpicult, I apologize for sounding so harsh.

no, i understand. bad day for me. i know the wastegate doesnt go there, so i seriously dont even know why i posted it. so, all is good now.

to answer your question...a wastegate dumps excess exhaust fumes out of the exhaust side of the turbo to keep it from over revving. this is the boost controll you were thinking about, it regulates the boost pressure

someone correct me if im wrong but im almost positive thats what it is

i know what it does i just can never put my thoughts into words...if im not making any sense here thats why

i thought the wastegate controlled by spring pressure the amount of boost a turbo was able to build up. does it do this by letting pressure out or releasing the pressure at a certain point? does that question make sense...its late

Yeah, sorrry Stir. I was having a bad day, just flunked a midterm that I thought I did well on. :) Anyways, to answer your question, the way a wastegate works is basically imagine a spring and a plunger. Basically, you have a vacuum line coming from your intake tract or your intake manifold to your wastegate. What happens is that the spring has a certain spring tension. This determines your basic boost level. For example, say it is at 5 psi. Well, when your turbo has compressed 5 psi of air, this air is going into your intake tract. This 5 PSI of air will also go into your vacuum line leading into your wastegate. What happens is that at that pressure, the spring starts to compress, opening the plunger, preventing your turbo from compressing the air anymore. That is how you get a consistent boost setting.

How boost controllers work is basically putting another plunger and spring inside the vacuum line. What happens is that the spring in the boost controller has a stiffer spring which doesn't let as much boost go into the wastegate. For example, the wastegate opens at 5 psi. What you are doing is fooling the wastegate to open later with a boost controller. Since the boost controller has a stiffer spring, it prevents the actual boost from reaching the wastegate until a later time, whcih allows the turbo to continue to boost more. In order to adjust the boost on a boost controller, what it is doing is basically using the theory of F=kx where k is the spring constant and x is the length of the spring. You adjust the boost controller by compressing the spring more so the spring constant goes up, therefore, you have a stiffer spring. The boost hits the wastegate later, and voila, you have more boost.

A BOV is kind of a reverse spring/plunger setup. It relies on a fast change from positive pressure to vacuum to kind of suck the plunger up, which leaks air out to the atmosphere or back into the inlet pipe instead of back into the compressor.

This is all a very untechnical and layman's explanation of how these devices actually work. But I think it gives a good enough idea of what is actually going on in some of these components.
