Turbo D16y5 172whp-163tq
 

Stock D16y5 in a 93 si.
y8 intake manifold with 450 dsm injectors.
converted to obd1 running chipped p06 with crome pro.
xs turbo manifold, mated to a ihi rhb52w (vj17) turbo off 87-88. converted to external wastegate. Using a 38mm Tial wg. with open dump tube, exits next to balancer.
johnny racecar intercooler, 2 in pie fro turbo to intercooler than 2.25 to the tb. smaller piping for fast spool. Tial bov. black coupler and tbolts all around. Custom 3in downpipe.
to stock exhaust. Planning on putting in electric cutout. Open dp for track for now.
Here is the Dyno graph. It was really hot outside. 104F.
Car on 6psi with boost leak(found later that day). more boost=200whp vtec-e!!!

sweet! Stock exhaust too!

bigger exhaust would probably help out a bit... just a thought!

Re: Turbo D16y5 172whp-163tq
 

nice power on 6psi from an rhb5. they arent the biggest of snails. just curious whats the vtec set at? i think stock its like 2800 on the hx motor

Re: Turbo D16y5 172whp-163tq
 

Thanks. Took turbo apart to reclock it and it was absolutley perfect, especially for 23yrs old. No shaft play either way beside minimal play turbo have.
Been messin around with it, seems best about 2700-3000. Got it set at 2752 now. kicks real hard.
its defying what everyone thinks of the d16y5. With so much more potential.

nice!
post some pics of your setup.

Re: Turbo D16y5 172whp-163tq
 

Here are some pics of my engine, dp, intercooler set up. 3in dp custom fitted to the stock o2 housing of the tbird from a random 3in pipe from the salvage. A nice custom fit.

hope the manifold holds together for you!

Re: Turbo D16y5 172whp-163tq
 

just over 1000 miles. Most break due to low dp clearance to the ground. Not the case here. Plus i reenforced it. Also got a cast manifold, finishing up the p&p if it breaks.
Manifold really helps on spool up over cast.

fun setup i bet

Re: Turbo D16y5 172whp-163tq
 

What did you use for tuning? What kinda tuning setup did you use? I know this is an old thread. I'm interested in turboing my hx

Re: Turbo D16y5 172whp-163tq
 

Do you retain the VTEC-E with your chipped ECU?

Re: Turbo D16y5 172whp-163tq
 

looks good. i have a turbo y5 too. pushing 12psi from a generic t3/t4 on the completely stock motor. holding up pretty good so far. good luck with the 200hp goal it should get there easy =)

Re: Turbo D16y5 172whp-163tq
 

What was used to tune this motor and like mentioned does it still drive smoth out of boost?

^^^ LOL

sometimes reading on our own to find out information is just too much work

Re: Turbo D16y5 172whp-163tq
 

Lol yeah I was half asleep and didnt wana edit.the post oops

Re: Turbo D16y5 172whp-163tq
 

Im thinking if you got a newer turbo with a better design and compressor map instead of some 25 year old snail, your 200 benchmark can attained easily..

Good luck on your build buddy!

Re: Turbo D16y5 172whp-163tq
 

i miss my turbo single. very nice

Re: Turbo D16y5 172whp-163tq
 

How did you get past the primary and secondary o2 issue with the turbo manifold?

Sorry for bringing this back to life....

Re: Turbo D16y5 172whp-163tq
 

Did you do anything to the motor or is it completely completely stock? What ECU are you using and how much HP are you pushing?

Re: Turbo D16y5 172whp-163tq
 

try reading! everything you just asked was stated in the very first post

Re: Turbo D16y5 172whp-163tq
 

What exhaust should I use for a d16y5 because I can't find much

Re: Turbo D16y5 172whp-163tq
 

Cool to see people boosting the hx motors i have a 2000 hx and i had my bone stock y5 boosted on 12 psi for a few months with an ebay kit on hondata the car was so much fun and would keep up with stock sti veloster turbos and a few other cars. after about 6000 miles of abuse she finally blew the headgasket but was fune while she lasted lol.
