97 BB6

after much debating about my next performance mod my friend talked me into a greddy turbo for my d16z6. My motor has a little over 130,000 miles on it so I want to have it rebuilt with some new pistons. If I did this what pistons should I use, and what PSI could I do safely as a daily driver?

racecarpete

i hate saying this, but add up your costs.
Rebuild with pistons & rods 600
Greddy turbo 1500
(recommende) intercooler 300

total 2400

You can get a swap for this. You might want to consider a b18b, these can be had for 1800-2100 and you get a low mileage engine. later

racecarpete

well if you don't want to swap, do a compression and leak down check on your current engine. With the greddy kit you can run up to 8 psi no prob, some say 10 but i wouldn't on an engine with that high mileage. Later

97 BB6

yeah I considered swapping and don't want to. I want to work with my sohc. I don't know anything when it comes to turbocharging, but what psi could I run with new pistons and rods? What 1/4's also? I plan on an intercooler later.

Don't build a d16z6 engine. It's not worth the money. Get a swap instead.
I'm telling you this from experience.

I had JE pistons and Crower rods with my Greddy Turbo kit. I was boosting 14 psi and I only managed a 14.063@101 1/4 mile. What a waste.

P.S. And it wasn't my driving skills that sucked. I wasn't granny shifting.

I just wanted to try something different than just swapping like everyone else, no offense. I would if I had the money, but I just don't trust them too much either. I love my motor, it runs great and I want to stick it out with it.

The Factor

yea i 2 have an ex and i've heard that turboing is just not worth it...but hey if u want to go for it...i wanna get a swap in my future but 4 now thats not even a possibility

Lowness

well if you really really want to keep you motor then.......

Get JE pistons 8:5 compression. Might as well change the rods while you have it opened up. They are the weakest link in all hondas'. The greddy turbo (TD04H) and its internal wastegate can't really boost past 16 psi. Your built motor can handle any thing the greddy turbo kit can throw at it. That's only if you tune it properly. With the Greddy kit you can probably make 200-210hp at the wheels MAX.

However if you want real power from your built D16Z6 get the F-Max turbo Kit.
You can get 230 + hp easily at the wheels from this kit.

What is the f-max turbo kit?

i agree

swap=lazy. Build your D16 for the same amount as a swap and put more power to the ground than them. Why not supercharge it and be putting more power at 3g's than everyone else with a b16 at redline!! I too am sick of hearing swap. I haven't ever really been impressed with a stock b16( don;t get ahead of yourselves by trying to say I don;t like the engine- it's increidible when built). But why not build the d16- it's a good engine and a lt cheaper to replace.

You can find turbo kits for waaay less than that...I got mine (with fmic ) for about 1350....Keep with that sohc baby!

Don't swap unless you want to. See what the SOHC can do! Im boosting my D16A6 or i might get a VTEC head and then boost.

loudsubz

The majority would say swap. I say leave it and do work on it. When considering in Canada a full b16 complete swap goes for around $4500 installed, you could take that $4500, do up the engine, strengthen the internals like said, and get a custom turbo for it, and put down more power than the b16 stock.

Lots of people will say 2 cams are btter than 1, but to make a SOHC make some nice numbers and run good times gets alot more respect from me than someone with a swap.

I've seen a d16z6 with over 20 psi of boost make over 500 hp, of course alot of work was done, but its doable.

97 BB6

thanks for your support sohc people. now, does anyone have any suggestions on the pistons that I should use, and this may be a stupid question but do they come with new rods or what?

D16Z6racing

I stayed SOHC. But I need a new clutch, tranny, axels, and rear brake set up before I can use my turbo kit. I hoping it sells so I can buy the stuff I need. Brand new in the wrap still.....and I won't get to use it.

TurBoXBirD16

if you WANT to show the power of SOHC...
don't just rebuilt your engine with OEM pistons or rods...

you want to put few thousands if you want serious power..

and if you are rebuilding your engne for serious power, you would want custom turbo setup or drag or revhard, but not greddy...


good luck

i suggest you go SEARCH on the Force Induction forum

If not greddy, then which other turbo setup is reliable and smog legal?

UpstateCivic

F-MAX is the way to go. Stock internals @ 12psi put down 225bhp on a 96 EX. Now imagine if you beefed up the bottom?

Get compression and leak down. If its ok, turbo. I would go with a greddy. The compressor size is much better for a z6. The initial greddy kit is your bare minimum, so when you start adding parts it kind of becomes custom anyway. I wouldn't worry about internals for now. Upgrade smart and tune the **** out of it. There is a fellow in Dallas running 15psi on a stock internals, I kid you not (that is with a little lower cr however). If you ever do feel you need more power or blow the engine, swap in a b16a and get a new manifold so that you can transfer over all the parts off the z6.

97 BB6

I just checked out the fmax site, that sounds like a good set-up. I just can't afford $3,799 right now. I can barely afford $1,500 for the greddy kit. damn, now I don't know what to do?

As long as the engine is in good working condition, you should not need to switch the pistons. However if you do, just go with some SRPs. GReddys kits are really safe. I think that GReddy kits don't put out the most hp, but they are definitely most complete when compared to others. I have had the APexi turbo kit and was tempted to put the GReddy blue box on for safe measures.

ck279

The Apexi kit is another excellent choice. Fit and finish is supposed to be A+. Not to mention is uses an IHI ball bearing turbo. The optional GT intercooler is not only menacing looking but highly efficient.

Here is an article/pictures from Turbo magazine on their installation and dyno testing of the kit. The numbers speak for themselves.
http://www.turbomagazine.com/tech/0108tur_apexturbo/

Here is a guy on the SOHC turbo board (daveG) who has a nice setup with the Apexi kit:

POLLO

What fuel management were you using ? and in what kind of car is this in ? how much did it weight ? Was the car tuned ?

1/4 mile times do not mean anything if the car is not tuned to its full potential.


BTW take an 92 to 95 Civic Si ( assuming that's what you have) and put a b16a swap and sure as hell you will not be near 14.0 in the 1/4 mile.


The only reason why Im picking on you is because the poster was looking for suggestions into building their motor for turbo.


Swaps are nice, been there done that, many times, now Im building a SOHC just for fun. Please do not make this thread into a SOHC vs DOHC swap.


To the original poster, these guys have bunch of useful information so do not be discouraged. Its for fun that we do this after all don't we ? So enjoy, I'll tell you my set up to far.

DC sports turbo manifold *new * rare piece
T3/t04e .48/ar 57 trim
tial 35mm wastegate
greddy type 31 intercooler
DSM bov (might upgrade to a type S or equivalent)

Motor

d16y8
b16a rods
toyota pistons
blockguard
arp head studs
quaife lsd
clutch(havenot decided)
lightened flywheel(have not decided)

fuel mgmt
Hondata
DSM 450ss
walbro pump
And a damn good dyno man

Im sure im forgetting a lot of **** here but this is my first time boosting a SOHC so I went cheap on the internals courtesy of Turbopanda with this high boost budget set up + other tricks up my sleeve . I mainly choose this turbo because i do plan to go as high as 18 to 20 psi and if this motor blows up, Im sure i'll have another fully built and sleeved 1.8 or 1.7 ( not sure yet) SOHC shortblock sitting here.

uhhh, do you guys know some kind of secret that i dont know, Im assuming your talking about a GSR swap.. right??? ok if say you did get this for 2400 it would be a miracle... not to mention, lets just say this guy doesnt have time and the knowledge and equipment to do a swap himself so hes gonna need a shop to do it. LET JUST SAY the shop isnt going to do it for free..... and they charge him a grand just like any other shop would, here we are at .... 3400. BUT lets be realistic and figure the complete engine tranny ecu and wiring harness cost 3500 like they do.. then ur at 4500 installed. and now you have a mid 14 sec car, for 2x the amount it would be to turbo your current setup. ......"oh yah well then you can turbo the GSR engine..." yah well guess what., last i checked turbo kits for B series motors werent free nor cheap, and install is also gonna cost you. on top of fuel management.

THE BOTTOM LINE.... if you want a good platform for a 12 to 13 sec car. then buy the GSR swap or LS swap. if you you want a FUN setup which isnt going to kick eveyones *** but is still FUN to drive and you get all the bells and whisles of a turbo setup than do the greddy kit. find a used kit for a G. ppl always sell them cheap. and last i check GSX intercoolers cost about 50 bux at a junk yard or used. the choice is up to you. from my experence. i payed 2600 for turbo kit (brand new) with GSX IC,. Blitz BOV, FMU, missing link. and pretty much all i needed installed from AXZ tuning in NYC. granted i only run 14.8 @ 6psi but i bet there arent that many GSR swaps in EX coupes running that... just my 2 cents. hope that helped. -dave
