 Post subject: D16A honda pistons
PostPosted: Sat May 10, 2003 8:01 am 
I'm currently investigating a piston from a D16A engine,as nobody wants or can't give some info on this.<br>I got a set to see,it's the same size as the g16B (75MM) also it's high compression as the SSGTI one,piston pins are the same,the suzuki pin fits on it,just the D16A piston is slightly higher than the suzuki one from the pin center and up,about 0.10 mm i guess,still have to measure it precise.The intake valve notches on the D16A piston is a bit littlier.Even the G16B piston rings look like that they can fit.<br>I'm researching this pistons,soon i'll post some pics and more concrete info on these pistons.<br><br> <p></p><i></i>

Yep,i'm still busy re-building a friend's gti,soon i finish i'll keep going on with the research.Due that the honda piston is +/-0.15mm higher,i need to install it in the block with the head and turn it by hand to see if it will hit or not the valves,thus time consuming.<br> <p></p><i></i>

Try this: <!--EZCODE AUTOLINK START--><a href="http://www.heeltoeauto.com/dseries/dseries1.html">www.heeltoeauto.com/dseri...ries1.html</a><!--EZCODE AUTOLINK END--><br><br>The D16A1 piston (88-89 integra and not listed in the previous link) have, if I remember correctly, a 7.2 cc dome and a 29.5 deck-height. I would suggest tu use the honda ring. Just bore and hone your block to honda specs. I can check in my shop manual for all the piston to wall clearance numbers.<br><br>Are the suzuki piston pin floating? Cause the honda pin is not.<br> <p></p><i></i>

Sorry, the 29.5 deck-height is for te D16A6 (88-91 Civic Si).<br><br>The correct deck height for the D16A1 piston is 29mm. <p></p><i></i>

People often use G16B pistons in a D16 Honda to lower compression.

Could we use the honda piston for high compression?
I want to take a g13bb to 11.5 to 1 with the highest lift cam offered by Tighe which has higher lift and duration than possible with the g13b and also the needed springs and titanium lifters which are 35 dollars each.
(but you need 16 of them) There is supposed to be an off the shelf Wiseco item that doesnt need any mods for the g13bb which has the same valve angles as either an xr250 78mm or the gsxr1100?.

Anyone know the valve angle differences .......

between the g13bb SOHC 16v and the g13b DOHC 16v? Apparantely Ian in the UK knows but has been abducted. :lol:

G13bb has bigger valves and better port design.
It also is a very reliable engine unlike the heads found on baleno g16b.
My 1999 suzuki carry has done 170,000 kmls without a hitch and my friends over 260,000 ks also without a worry.
There must be a better cast for these models.... as even suzuki sport agree the suzuki carry engine has the best heads.

just do the math. do you know how to check your compression ratio?

Hello.

Please could you try and find out the weight of these pistons. The std 74mm bore G13B piston weighs 220gms with the rings. Or if you can't get the exact weight maybe compare it to the G13B piston by hand and see if its substantially heavier. I would be VERY grateful for this! :D

The D15B2, and the D15B6 use the same pistons as the D16A6. The D16 is just a stroked D15. Well... actually... the D15B6 is a 8 valve, and the D15B2 & D16A6 are 16 valve. I know that it is easier to find the D15's in the scrap yards, mainly because they were in all Civic and Civic CRX from 88-91, all STD, DX, LX, and HF models. Beware though, some STD and HF models have the 8 valve motor. All Honda 16 valve motors say so on the valve cover.

I just quickly grabbed the info from my user manual. Here it is:

DX SI
Bore x Stroke: 75 x 84.5 mm 75 x 90 mm
Displacement: 1,493 cc 1,590 cc
C.R.: 9.2 9.6
Model: D15B2 D16A6
Induction: DP PGM-FI TBI PGM-FI MPFI
Type: ---Water-cooled, 4 stroke OHC, Gasoline Engine---

I have no idea about newer model D15's, as I am only throughly experienced in 91 and earlier Honda's. I believe that the D series 1.5 and 1.6 motors up to 2001 are all the same, expcept for the heads. Why else would I be able to bolt up a 2000 D16Y8 head to my 88 D15B2? I do not have the exact height of the motor, I'll check on that tommorrow. In comparison to my Sidekicks G16, I would say the Honda motor is smaller. Comparing against a G10 though, the G10 is definatley smaller.

:oops: am ,im gonna check compresion height again, cause i mesure with somthing else and comp height seem a little lower than earlier stated

http://www.teamswift.net/viewtopic.php? ... c&start=25

can anyone tell witch has the pin more in the center of the piston??? if you change the rod angle such as moving the connecting rod more to the center of the piston, it dose'nt put as much stress on the cylinder walls on power stroke. aka less friction more power :twisted: !!! even if honda just made a piston the same bore but moved the pin inward it would increase power. in one of the 70's cudas you could just put the piston in backwards and gain 25 to 30 hp! but there was major knock. but witch one is in the center more? cause i can't tell! :?:

Has there been any progress on this? Have these pistons been tried? What is the C/R or do the pistons crash into the head?

Thanks.

They have been used in a couple of engines. Machining is required.

Have you guys heard of JE pistons?

Here's their catalog....

http://www.jepistons.com/pdf/2006-sportcomp.pdf

Maybe someone can match the specs and use another piston, however I'm not sure why somone would want to. Might as well go with the stock style unless a different piston offers definite advantages over the stock piston.

I'm currently in Texas (Lackland AFB) and I'm away from my manual so I can't check the specs. Does anyone see a suitable substitute for a MK1 turbo piston?

Just in case you overlooked the post. D16 piston is cheaper than aftermarket and raises compression by a fair amount.
