To be?or not to be TURBO
ever notice the way the cat is connected to the intergrated ex.manifold,the outlet looks almost perfect to bolt on a turbo 
,anyone got any specs on the cat. flange.wondering if theres a turbo that can bolt right up to it?

Adding a turbocharger or supercharger generally isn't all that simple, although there are some bolt-on kits available for various engines.
The problem with adding a turbo to the TL is that it's already a very high compression engine to which you will try to force feed more air. Unless the engine was designed with an add-on turbo in mind, it probably won't have the internal strength to keep from grenading.
Unless the TLs engine was specifically designed with an add on turbo in mind (doubtul with high compression), you can look forward to rebuilding the engine with lower compression pistons, re-plumbing the intake and exhaust manifolds, and changing the computer to deal with the changes to the engine.

I was just thinking about starting a thred for this before you did! We all know Honda's are great at high rpms and dogs at low. If we had a turbo to compensate for the low end, this car would probably be an amazingly fast sedan. If and hopefully when a turbo can be intergrated, if a controller were available to boost psi up from around 7-9 like normal turbos up to 15 or so, our car could be an M3/Corvette/_____ killer. It does have a very high compression ratio, so unless there is any way around it we are stuck. Then again, comptech is coming out with a bolt on supercharger, sothere MUST be some way around it. TO BE, only a matter of time.

A SuperCharger would be a better bet, and even then you wouldnt get much as previously stated.
I wonder if anyone makes an electronically controlled Blow Off Valve. Something like when VTec kicks in or when your above X RPM, to lower the threshold on the valve to lower your boost. I guess you would just stick to a modest boost setting for the entire range and KISS.

yea especialy since im not much of a meat eater. a bigmacfish sounds yummy 
anywho getting back on track... I think a Turbo would be nice, but a SC is more ideal since we would have some pretty bad lag (try to think of that train in back to the future, that doc puts in those sitcks to make it go faster and its a huge jolt) well first it would be the turbo kick, then the vetec kick... i dunno our compression ratio seems a little high to work with also :-/

[QUOTE=Casper42]Turbo is the wrong thing to compensate for "Low End". keep in mind one of the biggest downfalls of the Turbo is Turbo Lag, which is because your waiting till the engine starts to crank out more exhaust in order to spool up the turbo.
A SuperCharger would be a better bet, and even then you wouldnt get much as previously stated.
---------
This is not necessarily the case.. there are some turbos which have imperceptible lag, and some superchargers which have tremendous lag (esp centrifugal types - such as vortech)
most the SC systems out there are designed for V8 engines which have horrible top end.. the SC's dont generate boost until very high RPM - so they do nothing for lwo end torque.. you'd have to go with a roots type design to get linear response.. (FYI comptech uses a similar twin sscrew whippe design on their accord and nsx SCs)
having said that. most all aftermarket turbo systems (which are any good) will generate more low end torque than a similar SC system - with yet even more top end HP.
as far as boosting a TL.. i know the NSX has a 10.2:1 compression ratio, and my understanding is this is about as high a C/R you'd want to run for forced induction.. you may have to build the engine with lower compressoin pistons..
If you do a search on nsxprime you will find many dynos which will support this claim..
(In fact, you can see a single turbo nsx dyno which has over 400ft/lb tq at 4k rpm... and over 320ft/lb at 3k rpm)
You can find a video of an 11.xx sec 125MPH run here:

Man theres is guy forgot who he was but he has a 2gen CL i think with turbo running 5.5lbs of boost and he is hauling
and he's on this forum check him out in the 2gen and he has a comparison video with a stock vs turbo.

im thinkin about it seriously ...and people dont undertsand 8-15 lbs of boost is fast that is a alot .. but the question is do u wanna spend the money on a custom turbo or comptech s/c that gives u probably only 8 lbs???

and he's on this forum check him out in the 2gen and he has a comparison video with a stock vs turbo.Ya no shit...that guy is in a CL-S+ turbo vs. a regular CL-S....holy shit, he fu%#s the other guy up!!!! a turbo would be sweet for our rides....too bad i just can afford headers as of now!!! hahaha,
hey all...seriously...your ride will never be as fast as the next car...so just be happy with what you have, mod some but dont expect to blow the doors off everyone!
