D16A6 turbo questions????

[89rexsi]

Hey I have a crx with the d16a6 and it has around 100,000 miles. I want to boost it but what psi do you think my motor can handle and are the turbo kits off ebay good enough? And will the wastegate be useful at 3 to psi??

[95GSRB18C]

i really wouldnt do more than like 5 psi. and make sure you get the proper engine managment. dont do some ghetto ass FMU.

[b16efhatch]

And dont do SS autochrome, engine management for 5 psi? dont think you would really need it, unless you plan on swapping and running more boost.

[riceburner700]

you could run 7psi all day long as you get it tuned... if you aboslutly had to get an fmu i would get some injectors and something to tune it with asap

7-10 psi is good, 5 psi isnt worth the money. pm me about turbo kits.

5psi? at this altitude. that's some toy shit.

Yes you need engine management for any amount of boost :killtard:
And 5psi at 5000' elevation isn't but like 2psi over sea level. Thats absolutely nothing. If I still had my turbo d i'd do 14psi on pump gas w/ some decent injectors and a good tune. That would be about the same as running 10psi at sea level.

With good engine management you could run 8 psi all the day long. This is assuming that your motor is in good health. Hondata and Neptune are you best choices and we have Tobi at TC's Performance or Jeremy to do the tuning for you. A complete Hondata s200 can be found used in the $300's if you search in Honda-Tech.com or E-bay. Absolutely do not buy turbo kits from E-bay. I've made that mistake on my first turbo project. Your better off buying quality used turbos such as Garrett or stock Mitsubishi/DSM and then finding the manifold and piping's somewhere else. I can give you plenty resources of where to buy quality parts for a reasonable price especially on CRX's since I've put together a few turbo projects from B to D series. To be honest with you, a complete turbo build tuned with Hondata or Neptune will cost you up to $2000 maybe a little less if you have mostly used parts. Every project I've done has been within that price range and even more so if you want to do it right, you just have to spend some money on it.

Get a manifold and down pipe from Pang, engine management, injectors, fuel pump, and tuning from Honda Ghandi. I'm running 10psi on my Y7 and it runs and drives great. But that is due to good tuning.

you people spitting out boost pressure numbers need to consider the size of the turbo. a 14b on a honda motor at 10psi is moving more air than it is on a dsm at the same boost pressure and a T3/T04 hybrid is moving MUCH more air at the same boost pressure.

Manifold and downpipe aren't that big of a deal; a great budget setup would be an HF manifold w/ adapter plate w/ a 14b hanging off of it and a downpipe made from a 2.5"ID U bend from summit. Or maybe a log manifold since HFs are getting hard to come by. You dont want to waste money on buying hondata for that car as it's for obd1 while an EF is obd0. You can use turboedit on an obd0 ecu w/ some dsm 450s and tune it with a wideband; well you probably can't but i can :p. I garuntee a shop will want to charge you nearly a grand for an obd1 conversion harness; hacked up computer; hondumbass engine management and a tune. Not something a guy on a budgget wan'ts to spend.

For < $1000 if your'e not an idiot you can put together a decent homemade turbo and use some REAL engine management. A stock A6 can handle a 14b and it will spool very quickly. Done right that setup would be a force to be reconed with.

You're right to a point, but we're not talking CFM here. We're talking how much pressure the block can withstand safely. 10-11 pounds of pressure is about the limit on most D series blocks depending on their compression ratio. Thats what he asked, thats what he gets for an answer.

Now if you want to talk cfm then a 14b or t25 are the better turbos for D blocks. They spool quickly, hold 10-15psi without dropping off, and provide a decent volume of air.

Don't knock Hondata because it cost a little more. No matter what you use for a standalone, it's going to cost you something. Turbo edit may be the best thing to use for this application, but who is going to tune it? You still have to get an ecu chipped, spend the same money on the fuel upgrades, and get it tuned, and if you decide to tune it yourself, you'll need a chip burner, wideband, and a notebook PC. For some of us the better, cheaper road is to pay 400-600$ for Hondata and let Tobi take care of the rest, or Neptune and Servion for that matter. For me I like the s300 because I can learn to tune it myself down the road and the only thing I'll need to do it is a notebook and wideband. No chip burners, no romulaters, and I get open access and wide support commercially for the product I'm using. Not to mention someone to learn from first hand.

computerJLT can tune/chip it for him, and for pretty cheap. i had him tune my car with crome and i was very satisfied especially for the price. my car still isn't making a whole lot of power, but it is only on 5 PSI (due to lack of injector), and it runs 10x's better than it did with a VAFC, gets better gas mileage, and with 5 psi is just as fast if not faster then it was on 8 PSI with the VAFC. i am still getting neptune as soon as i get bigger injectors but thats cause i plan to run 20+ psi from a large turbo. anyways i would recomend computerJLT to anyone, especially someone with a mild setup like the guy in this thread is building.

+1 for him then:biggthump

Thanks boostedEG don't forget to tell them about your hellacious EGR problem :p i bet if we fixed that and upped the boost to an even 8 that car will be a tire melter.

I've already invested in all the hardware to tune obd0-obd1 honda; a lot of nissans; 1g dsm's; turbododges and a few standalones. EFI and turbo's are my passion for life :p

lol, yeah i guess that would be considered an EGR problem.
