d16a6 block, ZC dome pistons, d16z6 Head nad intake manifold, tune, makes great power in these small *** cars

EDIT a6 block so that teh ZC halfshafts/intermediate bolt up. they dont bolt up on z6 or Y8 blocks

The quickest, easyest, cheepest swap is a D16A1 from a 86-87 Integra.

Like E-AT Me said, find a wrecked car on craigslist and buy the whole thing for around $300-500, and swap everything, brakes, motor, wiring, ecu. Sell whats left salvagable, and scrap the rest.

Or Vitara Z6 with a 16G for quick streetable spool. All my stuff's at the machine shop right now, and my palms are all sweaty.

1grex

umm wow ok

mattliston

**** that lol

turbo isnt the answer for eveyrthing. in his car, my build I sugegsted would put down 120whp


plus 16g turbo spools slow lol, a VW GTI turbo hits 2-3 psi by 900 rpms EDIT on a fully stock d16z6

E-AT_me

the A6 block won't bolt in at all as far as motor mounts go and there is no bolt in kit. he'd have to fab all the mounts from scratch.. what's a Nad intake?

mattliston

nad= and

spelled it wrong. Z6 head flows the best, as does its matching intake manifold

you wouldnt have to modify the mounts too much, its been done before (z6/Y8 in that chassis)

for all I know, they may make swap mounts for it, or maybe they used to and now they are rare :dunno:

Nobody has ever made 88-00 D-series swap mounts for a 84-87 1/3gen.

Hasport and Innovative make B-series swap mounts, but the swap is expensive.

The easyest way to do it is, bolt it to a 86-89 D16A1 transmission, then fab the drivers upper mount to bolt to the SOHC Block.

mattliston

would it even bolt to teh d16a1 transmission? Im thinking the boltpattern is slightly off


not all d series are the same bolt pattern

When I had my D16A1 I picked up a running 86 integra for $500, spent a saturday putting it in and drove away that afternoon, took like four hours with no air tools. My B16A1 swap on the other hand was thousands of more dollars and took a couple weeks.

E-AT_me

look below for answer on trans.. i hate to be that guy, but if you haven't done the swap personally, please don't give out the information.

Turbo is the answer for more than 140whp out of a D-series, or earlier EWx/D15A, affordably. While 200-250 whp is not "fast" by the mainstream turbo FWD mentality, it's blisteringly fast on a road course without compromising a classic Si chassis' ability to handle.

Also, MHI not only makes a wide variety of turbine housings but their turbine shafts are significantly large so they don't break like the tiny shaft K03 failure turbos. Making 2-3 psi off idle on a D16Z6 is nothing to brag about, I've seen larger than K03 turbos make 10 psi at 1000 rpms on D16 as well as LS (big 16G's, actually, with 6-7 cm ported housings), and all of those setups are prone to compressor surge. You also get very poor gains below 2500 rpms with ~10+ psi, as well as the engine being more volatile due to the combustion event having a relatively long dwell time due to the engine rotating slower. All in all spool off idle isn't that great of an idea. Sizing a turbo a little larger, accompanied by a drop in CR, means everything works together well and the engine lives for a long time - while still being quick spooling.

Anyway, all of this is OT, even if it's somewhat relevant to something brought up along the way.



Fabrication of the upper driver's mount is actually trivial. I'd rather do that than take the subjective eternity of drudgery required to grind the driver's mount to fit a D16A1.

Both TJ Schmidt and myself bolted D16s to 1G Integra transmissions in ~'98, and there are several people who have done a LOT more than that and actually completed this swap on RPR/other sites over the last few years. It's kind of a shame that everyone doubts without a three minute Google on the topic.

mattliston

Im not the one who said to use the d16a1 trranny, I simply doubted it could be used with a more modern version of the D motor

Joseph Davis

I'd love to link to RPR, but last I checked Internet Brands had blocked a lot of other sites. None of my pics in my RPR Gallery will show up here anymore, and I don't care to copy and paste someone else's how-to without permission or in fact a good reason to - 90% of the 1G/3G community is on RPR anyway.

Rextec's build is partially hosted on his PB:








I can find multiple 1G Integra in the local pick and pulls, and the newer D16 are more powerful, fresher, and more common. Pretty cool swap, really.

E-AT_me

never said you did.
