This is almost getting to the point that it needs a FAQ.
Nathan used these in a d16y8. The d16y8 has a 75mm bore and a 90mm stroke length. Take the engine you plan to put them in and find out if that matches or not.
that will tell you if they'll fit.

From the research I've done, these should work in all of the following:
ZC (d16a8)
88-91 SI (d16a6)
96-00 DX (d16y7)
96-00 HX (d16y5)
92-95 Si/EX (d16z6)
96-00 EX (d16y8)

In their current state, they don't appear to work in the rest of the d-series engines because they are 75mm x 84.5 These include:

88-91 HF (d15b6) (but why would you want to anyway?)
88-91 DX/LX (d15b2)
92-95 CX (D15B8)
92-95 DX (D15B7)
92-95 VX (D15Z1)</TD></TR></TABLE>

The supra pistons are forged, and have lower compression, after reading... it looks like the compression will be close to 9.0-9.5...

THEY FIT so dont argue. just want to know if anyone actually use's this system, because i plan on buying it asap.
I want to buy package #1.

Anyone? anyone at all using this setup in their D series?

Simple

AccidentproWn

i always thought this idea was really cool i wanted to do it but went with a bseries

crxY-49

i would also like to know if anyone is using these. i thought about using this setup before.

rjardy

If I was going to build a D i would deff go with this setup. Turbopanda is a good guy to, he will do you right. that sounded bad but you know.

i always wanted to do this when i had my eg... seems like a really cool idea.

Simple

hmmm, so im seeing a lot of, "looks good, wanted to do" but very few "i did it it rocks.

rjardy

im turbo panda, he did it

Where has he been lately?? Did he ever get that Evo he wanted??

T-sohctec

Damn, am I the only one that used this setup????

I ran these in my D and tuned it to 250WHP. Unfortunately I had to take them out because when I installed the pistons I didn't install the oil control rings properly. The oil control ring cracked and then scarred my cylinder walls. But I assure anyone who is interested in this setup that the cause of failure was directly my fault, not the components.

When I ordered the setup I ordered 6 pistons so I am going to put them into another Z6 bottom end. My goal is 300+WHP daily, on nathans combo.
Nathan is a good guy and you can definately trust him to deal with. I think that the reason you don't see him online is cuz he got an EVO and moved out of the honda scene.

I'll never see a B-series motor, when I get a spare A6 block I'm gonna start saving for that set-up. Low compression isn't nearly as bad as everyone THINKS ( not "KNOWS", "THINKS" ).

My 8.4/1 compresion Z6 bottom, A6 top has full boost at 3700rpms with factory 1'' DX exhust piping from the cat back and a 2 1/4'' DP...

how much psi were you pushing? also, i know you have to "notch" the block, what is this, who can do it, and how do you do it?

Altered

What are the valve diameters of the Supra motor and the valve pocket diameters of the supra piston?

What is the compression height of the supra piston?

What is the pin diameter?

I want to get this on paper from a mathematic point of view and for that I will need all the factors listed above.

Altered

Also, has anyon bothered to check the valve angles to see if they are even compatable?

There are many variables that would have to be common for this to work PROPERLY

If someone can supply the above requested info Ill tell you the probability of this combo.

p0gi

turbopanda has already been running this on his motor

Altered

Just because it runs doesnt mean it runs properly or efficiantly.

His calculations for compression ratios are way off, I just noticed that by flipping through a few magazines. The compression heights are way taller than the D series pistons making compression a lot higher than what he calculated. Also, the valve diameters are much bigger from what I remember and the angles are nowhere near the same.

If I can get all of the factors Ill show everyone the begining to end in terms of spec comparisons and calculations.

p0gi

where did you get your specs. The pistons he uses are out of a 1g-gte engine which isnt sold here in the states, at least from what ive seen

Altered

Heres the first obvious thing I saw

Altered

I want to make somethign clear, Im all for this. If it works GREAT! Im in the porcess of building a boosted D16Y8 for my GF and would love to find a budget solution to internals. I had originally planned on using LS rods and a set of JE's. If this works Ill look into this.

He diffeence in compression height looks to be solved with the 3mm shorter B16 rods, it might actually over compensate. I wont know though untill I get all the specs.

Hmmm

I can get JE's at WD price (Friend of mine is a dealer) and I have several sets of LS rods laying around. Its cheaper for me to go with JE's and LS rods.

Ill still help you guys out with the numbers if someone can post up the specs.

p0gi

i looked at my stock p28 piston and the valve reliefs appear to be almost identical to those, the only difference being the notches on the side of the piston from the valve relief (dont know how to explain it better)

Altered

one more thing to add

134mm B16 rods with a 90mm D16 crank = a 1.48 r/s ratio

The D16 is already on the low side stock with a 1.52 r/s ratio, with this set up it gets even worse

nevin

uh o

TorganFM.

Bump. Has anyone else done this and calculated their compression ratio?

fjt

Why dont you use Suzuki Vitara pistons? Theyre also forged and will be cheaper than the Supra pistons(even brand new). They are also floating style pistons so that mean that u can put the rods in there w/o having to pay for a machine shop(which will save you even more money)This is what i am doing.
The only thing is that oppsed to the Supra pistons, the Suzuki Vitara pistons will yield lower compression.
8.5:1 on Y7 stock head, slightly higher on Y8 heads(around 8.7:1)

If you want higher compression the u could Mill the head.

Suzuki pistons $146 Brand new set(without a hook up YO)
Hasting Rings(For honda D series piston) $60
4 connecting rods(95)

No machining needed. Total $295
They drop right in any Dseries 75mm block

I got these pistons and rings through a hook up and even with buying Brand new Eagle rods I didnt spend more than $425 on my piston & rod combo.
