pistons

[maxassassin]

ok so i was wondering if all de series pistons are inner changeable. like if its sjut a swap over jsut yeilding different comrpession or woudl there be like valve innerferance or something along thosel ines.

They are all the same bore, the d15's have either shorter rods or shorter compression height so if you put them in a d16 block you would have insane low compression. They are not all shaped the same, if you search around there is a site somewhere that shows them all laid out next to each other. I dont think any will cause valve problems with any of the heads. Several of the heads are shaped differnt and should be used with the right pistons though.

Once again, he is correct. I don't know the differences on all the pistons, but I do know quite a bit about the D16A1 pistons, which is the DOHC D series from the first gen Tegs I believe. You can use those pistons, but your gonna need some head work done, cam, cam gear, some intake and exhaust work and alot of tuning. Those pistons will up the Compression up to around 12.5:1, so thats the reasoning behind all the work, ofcourse I don't know if your looking for a turbo application or all motor.

The zc pistons also are higher compression, but I think its around 11:1.

im kidna wanting all motor jsut to prove ot peopel it can be done. kidna liek the hodna tuner 400 horse d series build up. thats to prove it can be doen nad to spank the import tuners sti ha ha. but im wantign all motor/nitrous app but nto a big shot. 50 at most.

You cant get 400 out a NA d series.

My old set up was like this. The compression ratio was more like 11:1 like tsc said. I know this because with 2* advanced cam timing it took a whole year to detonate always running 93 octane. It was a nice set up and would burn tires through 3rd but also blow out a cloud of oil and richly burnt fuel... damn code 1.

im nto shootinf for 400 horse na and there is a 400 horse turboed set up. jsut to prove they can do it. im shooting for like 175ish n/a and i knwo thats really pushing it. with nitrous i hope to break alittle over 210 if i can reach my n/a mark. i guess i shoudlve mention the 400 horse was turboed.

[hondacivic99sivtec]

it's like tsc said, the zc pistons are gonna raise your compression. or just bore it out to 81mm and get ctr's. lol

hey tsc aren't the d16a1 and zc pistons the same???

There is a guy on D-Series.org that did a build with the A1 pistons and says he got 160 at the wheels with this setup, no NOS, no increase in rev limit either, the guy knows his shit with these motors and can answer just about any question about it.

Here is the link to the thread

I'm planning on doing this build with my race car once I get the CRX going, its a good build, especially if your going for a stock looking motor, which is what I need for the race car....we aren't supposed to do anything to the motors

[TheSilentChamber]

Right now I'm doing (well collecting parts) a d build which should be yielding in the 170-180 range- but its not going to be very streetable at all.

[DirtyD777]

you wanna spank a sti with a n/a d-d-d-D series? good luck..

[sblkcamaro70]

one thing i do know about this subject is dont put 8 vavle piston (hf) in a motor with 16 valves cause of the slotting on the top of the piston

[maxassassin]

actually the hodna tuner 400 hp d series i have been talkin aobut is a turboed app. so tis nto an n/a see me persoanlyl id liek ot spank some of the htigns otu there but not eveyrthing cause i know withot ua turbo i cant beat alot of thigns so id rather shwo my glory at the track.
