Boost Question

Along with my D16Z6 swap, I found a turbo kit that I want to put onto it. So I was woundering how many lbs of boost can the d16z6 take? Also how many lbs can my stock d15 take?

i like to be on the safe side.. as for the d15 if its dpfi lol 2-4psi..my opinion 4 might even be pushing it..keep in mind 2 fuel injectors..as for the z6...ehh im wiery..so id say safely 3-6psi and 6 to me is pushing it..the psi levels i gave u is for more of a reliable ride..as for ur max..well that depends on how crazy u are. im not one for pushing the limits with my car..

you cant just say "how much boost can it handle" because there are so many factors that you need to look at. if your boosting without any fuel management or any timing management you are going to blow the shit out of your engine. if you use 87octane gas you will blow it too. if you even want to think about using a D15B2 you need to do a MPFI swap. if you do it right you can run 7psi EASY on a D15B2 DD. and it should last a while. if you build the bottom of your d16 it would last longer and would support more boost/higher rpms.


lol i got so into it i forgot to mention the most obvious thing, a turbo setup wont last long if your engine isnt minty fresh to begin with (solid compression across the board and reliable internals like water pump, timing belt, etc)

u dont need to do mpfi to run boost in ur d15..theres several ppl that ran boost on a stock d15 and ran 15's.. but there is limits and i told u safe levels i wouldnt exceed unless there is fuel/spark upgrades..detonation is uh bitch!! there is also fuel injector mods done to b1/2's that will give ya more fuel..i dunno..my opinion id never think about boosting a d15 unless it was jdm..boosted d16's is a alright route to take..i had a t3/t4 mini me d16 and it was quite strong running about 5 psi on a stock fuel system..neways if u want great tutorials..checkout www.turbod16.com

Yeah, you can boost your D15, but its kind of a waste of time, don't you think? :shakehead

lol i definately think its uh waste of time.. but sumtimes money is limited and some ppl might be satisfied with a 20-30hp gain..i dunno not i:grinno:

just go with a 20 shot of nitrous you'll enjoy it.

spend the money and go with the turbo over nitrous.... I hated running out of nitrous, boost is always there when you need it....

I'm beginning to like this noob more and more. He speaks the truth.

yes very intelligent for a noob. he will go far.

just common sense

Like "welfarepc" said there's alot of different variables to consider, the easiest way to answer this question of yours is go to TurboD16.com and if you can't figure out the answers you're looking for there I'm afraid there just ain't much hope for you KodKingVegeta

The main question that you should answer right off the bat is; is this a going to be a daily driver? If you want a reliable boosted car you will need to make sure your turbo setup has what it needs to run without issues. The first good thing every turbo setup needs is fuel management - with the 4th gen obd0 ecus the cheapest and easiest way to get lots of control over your fuel management system is to go with a chipped ecu running something like turboedit. After that, you'll want to look at upgrading your injectors so you can get more fuel into the motor. Since you are forcing more air into the motor, you need to compensate with more fuel as well. There are dsm blue top injectors that practically just drop in without any rewiring. The next thing I would recommend is get some ARP headstuds and a good headgasket. The reason for this is that the factory head bolts will flex just enough under boost to allow the headgasket to blow. Your aftermarket ARP headstuds won't do this, they are made out of a much stonger metal and in turn won't allow the head to flex in turn giving you a much more stable engine. After all of this, the rest is pretty simple, turbo, intercooler, oil lines, etc etc, but your key components are the fuel management, fuel delivery system and to beef up the stock motor with the arp head studs. With this setup TUNED CORRECTLY you should be able to safely boost a D16Z6 or A6 with MPFI safely and reliable as long as you take your time and make sure all your hoses and fittings are good. I've seen a D16Z6 running 9psi for over 9 months as a daily without issues. So if tuned correctly I wouldn't hesitate to run 7-8psi on my motor as a daily driver. This is all built on the assumption that you have a good engine to start with. Now if you want to be a little safer, then definitely upgrade the internals of your engine with new pistons, rods and rings, but for the budget systems, I would say you should be able to run 7psi safely on a system with the right tuning. Sorry about the long post.

holy crap i dident even try to read 4 words of that message by 4g4d but you probly get it by now. i have seen people make 17psi passes on stock d16s. it all depends. homemadeturbo.com is where i learned everything i know. now i got a boosted ls 4d ef. well soon enough anyway. just do lots if research and get back to us with the hard questions you cant find by using the search option or google. they really help alot
