Nitrous, Super Chargers, & Turbos - d16Z6 turbo

Well guys, I am planning on going turbo on my stock d16z6 (pushing 108K). My question is really how much boost can the stock internals handle? I am planning on doing a remote (probably after-cat) turbocharger. And another question would be whether I need big injectors, high volume fule pump, etc., if I'm not pushing much boost? What would you recommend? It's a tight-budget project that I'll tackle very soon.

ORIGINAL: but why after cat??

Well I'm trying to hide it for one thing, and I already invested in a header(yesterday), and to go N/A with this setup I'll just have to put a short piece of pipe in place of it and be done in less than 30 minutes. Plus there will be less heat in the engine bay.

if you are trying to hide it, that wont help you. the cops have mirrors that they check under your car with for a cat.

The cat will still be there, and it's not the issue of cops. Trying to hide it from my friends who like to look under the hood before going at it:-D

and to go N/A with this setup I'll just have to put a short piece of pipe in place of it and be done in less than 30 minutes.

Surely with this setup you will have to change your ECU as well? every time you want to change between N/A and boosted?

you dont sound like a guy i would want to be a friend with if you wanna make them think they are racin a n/a car and then you secretly have a turbo in. better not be racin for $$$$ if ur gonna pull somethin like that

Hopefully that will not be the case. I'm still unsure about ECU stuff

Well I'm not gonna be the first one to pull stuff like that. We have a guy running a supercharged V-8 in the back of a beat up Dodge Caravan...with stock engine still under the hood...it's kind of a social norm where I live :-D

Well first of all, and after-cat turbo is a unique idea, but you should take a few things into consideration:

1) How in the world would you run the piping to your intercooler and filter? Those pipes are thick (much thiker than the exhaust pipes)

2) CAT produces a lot of backpressure, therefore restricting the airflow. I don't think you'll get enough air in the turbine to produce desired results.

I suggest to sell your header and go for a standard turbo setup. Your friends will probably hear your turbo spooling and blow off. Another thing is that there is no way around plumbing. When you pop the hood, your friends will see the pipes going from the turbo (the intake pipe will be much bigger than the OEM one. Another issue is the intercooler (you may get away without one if you don't run above 6psi, but I don't think it's a very good idea. Also, if you got a lowered car, you could damage the turbine if you hit a pothole or something. Therefore, if anything, try putting a turbo somewhere before the cat

BTW, did you now that there are caravans that are turbocharged from factory! I saw one earlier this week in a junk yard

I saw this one guy who put TWO turboed engines in an old beetle. One to drive the front wheels and one to drive the rear wheels... I guess that's one way to get 4 wheel drive. I have no clue how he got it to run properly (in synch). Totally ridiculous setup. But, it was kind of a joke car though...

it doesnt really need to run in synch, just the throttle. well, at least if its automatic. i dont know how the hell you would set it up for manual.

It is most certainly do-able! There are plenty of twin engine cars in the uk.
Ian Nixon's Renault 5 GT Turbo runs with twin engine and produces about 500BHP

I used to own one...gotta tell you that I miss that thing. The engine in there is a Mitsubishi 4 and is simply outstanding. I think that there was a certain time when almost all cars in mopar's lineup had a turbocharged version.

How about a high-flow cat and an intercooler somewhere in the area of the back bumper as LEVIII sugested?

ORIGINAL: LEVIII

Hey.............There is more then enough room for a turbo and intercooler under the back bumper.

I say.......................DO IT!!!!!



(with lots of pics!!!!!!!!!!!!!)


Thanks for a great suggestion. That intercooler under back bumper is not a bad idea.


And for everyone's info, the remote mount turbo set-up is not such a unique idea - they do it on trucks now.

Not sure if it would be a good idea to mount the i/c in the rear bumper area. Notice that on almost every FI car, the intercooler is mounted in a place where there's the most airflow from the outside (i/c would work more efficiently). Just look at cars like evo's, wrx's and srt's. You will also need long pipes for the i/c if you put it in the back. I would imagine that you would get faster airflow if your pipes are shorter. Just think, you would have to run a pipe from the turbo to the back of the car amd then back to the engine bay to reach the intake manifold.

mounting the intercooler in the REAR bumper?? In order for this to work, you are gonna have to make scoops to get air flow into the rear bumper... Not a good idea. In front, low to the ground is the optimal position fo intercoolers..

Someone might argue that the rear doesn't have an engine that will heat of the air near the i/c... in heat transfer, temperature is secondary to air flow. I'm not gonna do the calculation but for example, you will get better heat transfer from 1km/h air flow than 10 deg difference in temperature.

yeah, i think Leviii was bein a smartass and everyone thinks he was serious. and he said the turbo AND the IC. the ic is one thing, but the turbo too?

Well guys, I've got two stealth options now....either the remote-mount OR...the procharger kit if it is possible to fit onto my car...I will be calling those guys up and getting info...their site claims to have a universal kit

well i dont think itll be worth it because for one thing the amount of lag would be
unreal i mean you'd nail it count to ten and something might happen not to say its
a bad idea but if you plan on building a car with performance in mind and racing your mates
then it is a bad idea

Hey a turbo on a d16 engine is deff not worth it theres way too much to do to get the d16 engine ready for the power from the turbo you better off buying a b16a1 and putting a turbo on that it would be a lot better

It's not as uncommon as you think:

I sense turbo lag from hell.

Well if It's a small sized turbo it spools much faster so lag really should be minimal...more than if it was under the hood, but less than if I stuck a large one under the hood...

I really think that your opinion is biased. Yes the b16 is a almost a turbo ready engine with much more potential, but there's a lot to be had with a d16...and no wiring or ecu changes.(lazy me)

and a B16a1 would be a HUGE pain in the ass to get in his car. and you cant even compare the cost of turboing the stock motor to a swap AND a turbo. dont get me wrong, im planning on doing just that. but it takes awhile to come up with extra cash. for most of us, id say the cash is the biggest thing holding us back.

Uhuh...especially when expecting additions in the family and paying mortgage:-D

try living in cali. i heard that for the average person to live an average lifestyle in the sacramento area, they would have to make $21 an hour, full-time. yeah, im nowhere near that. damn home prices. damn rent.
oh well, i got a decent deal. but for the "good deal" i have on rent in our 2bd, 2ba condo, i could BUY a house in, like, oregon or something, and have plenty left over to build a fully outfitted garage with a lift and like 3 double bays.

DAMN! I used to live allright making 8.25 per hour. I'm NOT moving to cali:-D And I like our gas prices better.

its getting better here. i got gas today for 1.919 for 91. better than the 2.459 i was payin about 10 weeks ago.

down in the l.a. area its like 2.10 for 91

hah. theres some places down here in NC where it's only like $1.55 for 89.

I pay 1.79 for 89:( Moving no NC:-D

All the big gas station companies in NC are all around $2.00 actually (BP, Shell, Etc.), but if you know where to go you can get it real cheap. (Hah. Listen to me sayin that $1.50 is cheap for gas. I remember when gas was like $1.10 for regular)

shoot, i got it here for 1.06 like three years ago!

I remember .90 for regular...damn it

sheet right now its 1.89 for 89 and 2.09 for 91 in north idaho. this is why I dont drive my 76 dodge pickup with its big block 6.6l 8mpg just dosent last long.
