**If you impatient/irritable, skip to post #2 for Cliffs notes**

So after a two year stay in the state of denial, I've come to the conclusion that my JRSC sucks huge sweaty *****. There is just no way for it to make good power PERIOD. Nobody argue with me - I've done more research on this than anyone else on planet Earth. If you ever hear anyone argue in favor of a JRSC, it's only because they're noobs who are still living in denial.


That being said, please, I need help building a turbo kit for my D16y8. I hate to admit it, but turbos are the one automotive field where I don't know anything. I've tried to become educated on the subject but most turbo posts are more argumentative than educational.


So currently, what I can salvage off of my JRSC setup are the following:

Head:
DHR ported head
DHR valves
Skunk2 Cam gear
Skunk2 Springs
Skunk2 Ti retainers

Block:
Crower rods
ARP studs

Exhaust:
Full Kteller custom 3"

Other stuff:
ACT 8lb prolite flywheel
Clutch specialties clutch
Jimfab mounts
All suspension components


As you can see, I like to spend money on high end stuff. Money means nothing - I don't have much to spend, but I work my *** off until I can afford the good stuff. Whatever you guys tell me is best, no matter the cost, I will buy it.


So aside from what I will transfer to the new setup, I'm going to get a Benson block with matching CP pistons in a 78mm bore. My goal is the following - 400whp with on a combination of relatively high compression and relatively low boost - I really want full boost at 4k RPMs so it won't suck as a daily driver. That's not too unreasonable is it? I've seen 500whp D16 setups on H-T before. This is obviously assuming race gas. I won't need 400whp on the street and all I have access to is 91 Cali gas. Also, I will be retaining p/s and a/c.

What I need help with is choosing the following:
-New intake mani
-Good turbo manifold/downpipe setup
-Good turbo combination
-Good intercooler setup
-Good turbo cam


Thanks in advance. I know these kinds of posts suck both to read and respond to, but I don't care at this point. I'm very depressed to be getting rid of my JRSC setup.

 

Help me pick the following for a 1.72L fully built D16y8 turbo motor; pre-reqs are that I want peak power of 400whp on race gas and I want lowest possible lag.

1. Intake mani
2. Turbo combo
3. Intercooler
4. Turbo manifold/downpipe
5. Turbo cam

 

why not go with a b-series motor?
you are going to need a ball bearing turbo with that displacement, and a large one at that. perhaps gt35r. I hear gt3255 (not ball bearing) will spool good too. if money is no object get a full race a/c kit with a ball bearing turbo upgrape. Get a good EMS and tune. Seriously, 400 is alot for a DD d-series motor, built or not. I am going to go out on a limb and say, screw the numbers. A full race a/c kit with a GT28rs will haul some serious ***, but wont really go 400, just IMO.

I will be SOHC until the day I die . Besides the fact that I'm trying to be different (hence the JRSC), I already have about $5k in my car that will work with a turbo setup. So less work . Plus SOHC stuff is dirt cheap.

What about the peakboost kit? The t3/t04e it includes has 60/63 trims. What kind of trims should I look for? The full-race kit does look enticing because it's A/C compatible.

 

there will prolly be lots of lag on the t3/t04e unless its ball bearing. the full-race a/c kit with the gt28rs will be awesome on that setup, not 400 though, hmm thinking.

 

my friend made 500 on a d16 with a "blowzilla" from cheapturbo.com. i believe its a t3/gt40

 

You live in california, don't take chances with high compression and inconsistent 91 octane **** water. 9:1 compression, GT3071R, ported head, zex cam, and enjoy.

 

what kind of car do u have that ur boosting

 

^^^ It's a D16y8, bored to 1.72L.


I don't mean really high compression, just looking at a good solid 10:1. And yes, Cali gas sucks nuts, but I've been seeing good results with the $3/gal Shell premium 91.


And I've been looking into the gt28rs - it seems to be very well liked for street cars. What kind of peak power would I be looking at with that turbo on race gas?

 

Anyone? Peak power from a gt28rs?

I don't care what kind of good results you've been seeing from shell gas, it's still inconsistent as hell 91 octane. Trucker pulls up to gas station, trucker has too much 87 octane, not enough 91 octane. Leave premium tank half empty and drive home with a 1/4 tanker? nooooo, just top off the premium tank with regular gas and be done with it, nobody's going to notice the difference, right? I saw **** like that happen with regularity.

Think about it, what do you gain going 10:1 vs. 9:1 compression? "Off boost response"? Go look at Boosted Hybrid's comparison, that great off boost response was to the tune of 1-2 WHP across the board. Quicker spooling? Nope, they spool the same. Great top end power? Around 12 WHP at peak. That 12 WHP is more than made up for with a pound of boost. You can't notice the difference in power off boost. The throttle response is the same. One bad tank of gas, one heatsoaked motor, one ultra warm day is all it takes to ruin your car, and think of how shitty that feels when your nice brand new motor blows itself to crap, because I've been there and done that. All the extra risks associated with a 10:1 compression motor are simply not worth it.

 

Judging by your sig, I'm begining to think you are on some sort of quest

Anyway, I think the general consensus is that high compression DOES spool the turbo faster. And I've seen some wicked high hp high compression turbo dynos here on h-t.

 

I made 380WHP at 20 PSI on 93 octane pump gas with my GT28RS on a B16, and it spooled very quickly. I swapped it for a GT3071R so I could get over 400 WHP and I now make over 400, but I'd rather have the GT28RS on there because it made boost sooner and was more responsive.

I think high CR spools the turbo faster if the tuner doesn't know what he's doing with timing. Low CR makes more power with less chance of detonation, it just takes more boost. I've been running 8.4:1 CR for a while now and it works great.

JRSC is great for linear torque delivery, I loved mine for autox, but autox doesn't usually get above 60 MPH, and doesn't require much power. Any high power turbo setup you put together will probably have extremely non-linear torque delivery, making it challenging to use for autox or road course.

There are some other options as well, but I don't feel like getting flamed today, so you can e-mail me if you like, address is in my member profile.

I am on a quest, a quest to stop people from making bad decisions

The general consensus on H-T at one point also believed you couldn't make more than about 300-350 WHP on stock sleeves and that LS transmissions were better geared for boost. Higher compression does not spool the turbo quicker, go look at the comparison Boosted Hybrid posted comparing 9:1 and 10:1. Spool was unchanged. My old B16 @ 7.8:1 compression spooled the turbo exactly the same as it did at 10.2:1 compression stock. You wanna talk wicked dynos, look at some of the cars Mr. Evans has been tuning lately. B18C1CYA, 430 WHP on pump gas and 605 WHP @ 27 psi and race gas, 9:1 compression 81.5MM bore. The car that made 630 WHP @ 25 psi and 450 WHP @ 13 psi with a T3/60-1, 84mm and 9:1 compression. Mike01GSR's car making 425 @ 15 psi on pump gas and 516 @ 19 psi on race gas, 84.5mm with 9:1 compression. I don't know about you, but 450 WHP at 13 psi and 630 WHP at 25 psi with a T3/60-1, that everyone on H-T seesm to hate, is pretty damn impressive if you ask me. You have a turbo, lower the compression and let the turbo do the work.

Attribute great power and spool to a well planned motor, head work, cams, turbo, and tuning, not some magical difference based solely on compression.

 

we are building a D series civic right now, if you want to see a hardcore setup email me i can send over some pictures

You are compairing totally differnt setups. there are 50 million little factors that effect over all whp on top of compression. If you are on a quest to prove to people that higher compression does nothing, then back up your facts. other wise you are just rambling a bunch of b/s( i.e. the same exact setups manifolds, turbos, headwork, etc....) run one at 8.5:1 and one at 10:1 and see what happens. Stop compairing totally different setups and acting like it actually means something.

he said he wanted a/c and pc friendly. i don't think those are.

 

i'm running an equal length manifold with 3 inch downpipe and a/c and ps compatible.

IM silly sohc

yea i know he SAID it, he didn't prove anything though.

 

Isn't the manifold what determines if the setup will be A/C compatible?

he refered to the boosted hybrid post showing that spool was unchanged.

and i'm sure he wasn't gonna make up the fact that he said his own car spool was unchanged unless he just wanted to argue.

Boosted hybrid did a back to back comparison, that's more proof than you have champ

 

link me, i searched under his posts and didn't see anything about a compression/boost test
