I just bought a new tiburonGT 6 speed and want to give it forced Induction but realy
don't know where to start . I want the car to run a 13 or better but I know if I add 40 pounds of boost the 2.7 may not handle it . so what else needs to be done to the 2.7
and about how much will it cost$$$

40lbs of boost? Maybe im misunderstanding something but that is almost completely unrealistic. However if money wasnt a problem then i guess its not lol As far as i know their are no turbo kits out yet for the v6 so it would be custom everything and would be very expensive, maybe some nitrous would be a better option for u?
I found that very funny too. I'm not sure how much boost a v6 can handle, but 40 is overkill. Also, your best bet is to wait for a turbo kit to come out, because they already have a supercharger kit available for your tiburon. Either the supercharger or the nitrous is your least expensive.
That would be around 650ish hp.... going for full drag racer?
You might want to start with 8 psi.
ok, I guess 40lbs is to much I have some stupid friends that said 20 to 40 was what i needed I don't think they had any idea. But I have heard that supperchargers are not as safe as turbos. that kind of blows that thay have not made a turbo for the v6 yet i
guess I will wate for it to come out. what will it take to get the car from 178hp to 240
or at least 200hp? I realy want to smoke those new civic si in 1/2 mile but I don't want to break the bank...X)
who ever told you that s/c aren't as safe as turbos are not that bright. in my opinion sc are safer than turbos because of the fact that s/c don't have boost spikes like turbos and they are at a constant boost. the bad thing about s/c are that they take power to make power. s/c are downgraded cause you can't really bosst anymore unless you buy an upgrade kit or find other ways of turning up the boost. with turbos you will run into more problems if something happens.

Sup bro, and welcome to the forums. I'd try a forums search; there's already a boatload of hard info on what you'd need to do to the car, and budgets to help that shopping list of yours.

40psi is basically what the older F1 cars were running back in the day before they banned turbocharging; 30psi is what dedicated drag/street drag or circuit cars run, but these need very constant rebuilds. I'd be thinking more along the lines of 20-25psi. Now the trick is this; it isn't your boost pressure entirely; it's how much of that pressure makes it into the cylinders. There will always be pressure losses in the turbo system; so, you can gain back what you lose with a better designed kit. The key here is flow rate. To that extent, you might want to look at companies like Extrudehone for some headwork, matching of your plenium to the ports etc. etc. etc. We also have the issue of cavitation; too much pressure in the system causes turbulent flow. Fising the system so that turbulent flow at high boost does not occur also usually means that you will lose charge velocity lower down[less torque; which is what you need to get out of the hole]

In order to help us help you better, please try to answr these questions:

-What is your budget? "Money is no object" isn't an answer; plenty of projects have been left uncompleted when the money runs out eventually. You will need to establish a working budget before you even begin ordering parts.
-Is the car your daily driver?
-To what extent are you willing to go within your budget to get the results you want?
-Where do you drive the car, what routes do you take, and how do you drive the car? Please describe some of the roads you most frequently take; this helps us get an isea of the kind of setup that will benefit you the most.

Hope that helped.:bandit:

Due to the layout of the V6, turbocharging will always be a problem because of the lack of proven aftermarket exhaust manifolds available.

Most people on here have gone for supercharging, which appears to be a far easier option with this engine.........use the search button & check out `Ripp`.

thanks for the info I want to stay under 5000. THe project is going to take a fue months I drive the car every day to work so I want the car to be leagal and **** and I have a good tech to do the job but even a tech that you trust will try to sell you somthing that you don't need if I but s/p what else will need to be done?
i would have to say supercharging would be your best best.. and heres how i would do it..

http://www.rippmods.com/products/products_list_details.asp?menuid=3&productId=107

along with there long tube headers and a custom exhaust system.. would be roughly 5k. GREAT proven system. awesome quality, lots of add-ons for the motor.

with the basic kit you would probably set yourself around 300whp.. get up to the stage 2 with aftermarket intake manifold, better tuning, etc. roughly around a 7-8k setup and youll be in the 400whp range..

with that power youll be spanking alotta shyt.. i reccommend supercharging..

constant boost, proven applications, easier install, more reliable..

I don't think superchargers are more reliable than a turbo. a turbo doesn't have a belt that can slip or break. If your having a boost spike with a turbo, then you don't have it setup properly. You should not have any spikes if you have the proper equipment. I have seen superchargers spike as well btw. Roots type blowers suck for 4 cylinders anyway. Centrifugal are better but still, you have that parasitic drag killing your power before it makes power.

T.hammerdown:
If they do not make a Turbo kit for your application and you do not have the mechanical aptitude to produce your own kit, I would say go with whats available. if all they have is a supercharger, and your bent on forced induction, then thats all you can get. However if you can put together a proper turbo kit yourself, or know someone who can do it and won't rape you on the cost, By all means go Turbo, you will not be disappointed.

as far as boost pressure, if you want to see what your rods look like if they were sticking outside of the block, then by all means try and run 40 psi. Your engine is a high compression engine so it does not take a lot of boost to make power. I would say as suggested earlir you start at 8 psi, and since I believe that engine is 10:1, no more than 10 psi. that should produce a lot of power and torque for an engine that began life as naturally aspirated.

anyway you look at it, your gonna spend a lot of $$$$. the turbo is only part of the equation. you have to fortify your fuel system, get a clutch that can handle the extra load, and have something competent to tune the engine with so it doesn't melt. also, an exhaust system to compliment your new snail. Gauges to monitor, a wideband to aid you in tuning and to make sure your a/f ratios don't get out of hand at any given point.

seriously if all you want is a decent power jump with out breaking your pocket, get some n2o. a 50-75 shot won't hurt the engine none and it will give you a nice boost. Its just refilling the bottle sucks.
