I know the engine has some potential and I wanna keep it rather than doing a swap. I have heard mixed things about gude, mostly bad. right now I have i/h/e. I want to eventually do some headwork but keep the car faily reliable. When upgrading the head do you have to upgrade internals or are they ok? along with the head, I would do fuel managment and stuff. thanks everyone. it would nice to see some of your set-ups and what kind of power/times/ and reliability you get out of it...

 

Just get a swap out the D16A6 and get a D16Z6 or D16Y8 head. You'd be running at least high 14s. I'm sure you can find a D16Z6 head somewhere for cheap. If your mechanically inclined it shouldn't be that hard.

 

I kind of want to stay all d16a6 I was reading up on the exospeed cams. anyone else have them? who else makes good high-end but streetable cams(hp #'s if possible).

thanks again, shea.

 

The D16A6 motor isn't a bad motor, but I've heard with some good headwork and a good performance cam that the bottom end would last too long, especially the rods. Once you get up near ~145 flywheel hp the rods willn't last too long. You can get some good power out of a D16A6, but it all depends on how much money you want to spend. Buildiing the bottom end with stronger rods and high compression pistons and doing some head work and a cam could make for one mean D16A6. What the question is "Is it worth the money?"

 

I'm planning on doing an a6 turbo project this winter. Will be doing block and head work and running ~14 psi. If anyone is interested, I have a d16z6 motor for sale.

Yeah, I beleive it's a wonderful little motor...totally under rated hp figures from factory. My friend's dynoed 111 at the wheels with merely I/H/E.

 

rebuild with A1 88-89 Teg pistons and forget the VTEC head.
14.7 on 16" streets and full interior in a 91 CRX (not mine!)
14.3 on slicks that wouldn't hook up.

 

Ive heard nothing but bad about most cam companies...

Gude-Very Bad
JG-Kinda Bad
Crower-Bad

 

What about Crane?

if i was u id go with d16Z6...got mine running with a s/c. friend of mine sed running with a d16y8 head will add bit more hp with a higher comp ratio... but ima go with a s/c d16y8 motor. heard all bout the connecting rod problems in d16's so i plan to do some bottem end work before i get it swapped into my coupe. ill let yal kno how its coming

 

yes, I am thinking crane now. Does anyone know how the cranes perform? And with the powerband being raised to 7,500rps, do you need a new ecu? I can't believe you don't need to upgrade the valve springs and stuff?!

 

yea yea QUAD throttle bodies!

 

who makes individ. TB's for the D16a6?

so good words about Crane? any?

 

As for the throttle body, all I've ever seen are Gude, JG and RC, and barring a custom setup I've never seen ITB's for the D16A6, only carbs...i've read and heard good things about the RC...where all all you guys hearing this bad stuff about JG?

IMHO the D16A6 is a very highly underrated engine, and with a little work (i/h/e, cam, gear, ECU, maybe ignition and FPR too) and some decent driving skills you will be running with newer Si's and even GS-R's on the street...

Screw running with them, I'm going to kick their asses!!! :D But I agree with you about the underrating on the d16a6. Anywho, I plan on using the Crane cam, mainly because they make one for boost applications...but they're also a good company. If I could get my hands on a Y8 head I might bolt that on the engine as well (granted I'd need a different cam). I have a full Z6 in my garage (along with a ZC, grr I need to sell the damn Z6) but I dont want to deal with the distributor ****...had to do it before and am sick of it.

I just bought this car and will be looking for a cam soon

Full Port/Polish
Shaved Head - 11:1 compression
Balanced and Blueprinted
AEM intake
DC header
Bosal Exhaust
RC balanced injectors (not sure what size)

Any suggestions? times?

I dyno'd at ~125hp in my da16a6 at ~200,000 miles, and the motor still pulls srong at 280,000+ miles. Where did you hear that from? But then again, this motor has no headwork, just a mild cam.

 

would it be safe to take .020" of the head and run a y8 headgasket with a 272 degree .425" lift cam. that should be a over 10:1 compression maybe like 10.5:1. do you think that i will have enough valve to piston clearance? with a good ported head that should make around 135- 145 flywheel hp. right now i have a stock head with that big cam and i/h/e plus a mugen spec chip, and it pulls hard at 5k on up, but the bottem end power sucks. after installing my ported head and adding some compression i should be in the high 14's or low 15's

 

Back when I had a D16A6, I routinely lost street races to Tercels and ran high 16's in the quarter mile. This is why I became a B-series guy.

 

hey matt.. havent seen you in a while.

Back when I used to street race with my D16A6, I used to win alot against Type R's, B16, GSR's in Civic's. I guess that is why I stuck with the D16.

i smoked a few b-series cars today in my all motor d16...
if you ran a high 16's you must not be all that good of a driver. i'm sure my crx runs low 15's maybe high 14's with a few minor mods (i'm not bull shittng i've own 13 and 14 second cars) i can't wait till my d16a6 is fully built

 

a simple D16A6 rebuilt with ZC pistons will run 14.6 on streets, 14.3 on 22x8x15 slicks.

The car was NOT gutted, even had a WW body kit and small stereo in the back. Once I saw James run his car, I knew I'd stay SOHC forever.

 

as far as the internals go, the stock pistons and rods should hold up to 250 crank hp.if your going to go all motor id use the y8 head like everyone said but if your going turbo or sc use the a6 head,it flows much better.my motor is completely stock internaly and im making almost 190hp to the wheels on 7psi boost,I also plan on using a 50 shot nitrous,still on stock internals,just very well tuned.ive heard great things about the exospeed cam,but they are exspensive.

 

Change the cam and get a cam gear.

Here's a complete write up I did on how to change a cam in the A6. Enjoy: http://www.geocities.com/slowmanef/d16a6cam.html

 

how high can you safely rev a good d16? i take mine past 7000 rpm all the time. but i have a fairly big cam,i,h,e, and a chipped ecu
