'88 EF DX Hatch with DPFI and 180k. I want to put another motor in before I go turbo. Suggestions as to what D series I should go with and what ECU? Use OBD 1, 2? I want as straight forward/simple as possible and i'm not looking to spend high $$ either. It's a winter beater that I want to have fun with....I'll be running stock internals, and just upgrade what I have to to make it reliable and run right. I have turboedit on my computer, could I/a shop use that to tune?

I want to:
Buy-->swap motor-->install turbo-->drive

I've been searching for a while, but i'm starting to get confused

 

you can get a z6 and boost it your going to have to go obd1, yes u can use turbodedit

 

No matter what BOOOOOST!!!!

Weather D or B...

 

Easiest swap would be an A6 or ZC with some Y8 parts. Then I would go Z6 with some Y8 parts, after that, I'd go with a B16 or something of that nature.

 

D16a6...simple cheap and easy, you can stay OBD0, and the it is really easy to tune a non vtec motor and you can make an a6 head flow really good, but even in stock its a good boosted motor

 

what does an a6 run on lets say, 8 lbs boost??

Thats a little vauge...but you can push most stock D series to about 200hp no problem whcih depending which car could get you into 13s or 14s to many factors to be specific

That's what i'm talking about haha! I was on D-Series.org and the D16Z6 was suggested. Let me see if I have this straight:
D16Z6= 92-95 SOHC VTEC and I have to convert to OBD1 and wire for VTEC
D16A6= 88-91 SOHC nonVTEC and I can stay OBD0
Which should be easire to come by? Any big reason why I should spring for VTEC besides the obvious? I assume tuning is more of a challenge? One more thing, what ECU would I use for each?

Thanks for all the help already

VTEC is over rated, SOHC isn't even real vtec anyways....Only reason it is hard to tune is because vtec has its own set of fuel and timing maps, just more to have to mess with, if you wanted a cheap upgrade go for it but if you plan to boost i say go for the a6, probably both as common and a6 will sell for cheaper

 

oh a6 or even the d16y7 would be a good choice I always forget about that, thats the non vtec 96+ civic motor not sure which models it was in

All hatches. Dx coupes, most sedans. Don't use there intake manifolds tho, they suck ***.

The A6 is probably the easiest one to turbo/tune.

 

VTEC rocks for one simple reason. Economy on the low lobe and power on the high lobe. That's why I decided to go with a Z6 over another A6. The OBD conversion was about $500 though, I bought most of it from RyWire.com...OBDI conversion harness, distributor conversion harness, and O2 sensor. I got my P28 from J-K-Tuning.com and my distributor from a dude on eBay who sells rebuilt ones for a damn good price...search for d16z6. I did my own engine harness conversions and VTEC/O2 subharness, which wasn't really that difficult at all.

A good tuner shouldn't have any problems tuning a VTEC motor.

You want to use a PM6 ECU with the A6 and a P28 with the Z6.

If I went with the d16y7 I couldn't stay OBD0 right? What would I have to change to and what ecu should I use? I only ask because i'll be prowling junkyards and the such. What about transmissions? Buy one that came with the motor, or use my DX trans?(180k) Thanks for all the helpfull info so far

 

if you get the tranny that comes with the motor on a 92-00 your not gonna be able to use it since it will be hydro.So you might as well just pick up a longblock and stick with the one you have or just find another cable dx tranny since they are not really that expensive.

 

oh and dont forget the mpfi swap

Well if you are just begining to work on your car do tese in seperate steeps, it will help you find any problems easier....you can and should stay OBD0 you may need to get an OBD2 harness to cut the plugs off of but always use the cars stock harness and can also use your intake and exhaust manifold so you just need the long block...

As for the trans the DX should be fine you could upgrade to the Si but they are only a little different and there is always the ZC trans but they are getting harder to come by and require new/different axles

I suggest you start with an MPFI conversion if you haven't already once you have that done and working properly you can swap in your new motor a6 or y7 should be a direct bolt in and little to no wiring required, when you did your mpfi swap you should pick up a 90-91 pm6 ECU (easier to chip when you go turbo and use turboedit) which should run either motor well (its comes in cars with the a6)

but if you find a deal on a sap you can always put the motor in and run it dpfi if you wanted I don't forsee any problems with that but pfi is highly suggested

On a side note ::wink:: ::wink:: I have most of the stuff you would need for the MPFI conversion pm me if you are interested
