LS wagovan finally running.

adamEFwagon · July 2007

hey i just got a b18a1 and im starting the swap into my wagon...so far ive only unhooked everything pretty much and taken almost all the AC out but on the firewall its a royal pain in the ass to get unscrewed......also about shift linkage which ones should i use and wiring harness since i suck ass at wiring should i use the harness off the wagon or the LS? ill get some pics up tomorrow of everything too

shift_wagovan · July 2007

I believe your are going to have to make your own shift linkages since wagon linkages are specific. Not 100% sure tho.

jpciii · July 2007

is your wagon dpfi or mpfi?

adamEFwagon · July 2007

since im an idiot i dont know what either one means

shift_wagovan · July 2007

Is your wagons motor stock? Im gonna take a guess and say yes.

jpciii · July 2007

Is your wagon an all wheel drive model?
Is your motor stock?

adamEFwagon · July 2007

front wheel and yeah its stock

jpciii · July 2007

read the first couple paragraphs here:

http://www.4gcivic.net/wp/mpfi.html

if you want more technical info about doing a dpfi to mpfi swap, here are some more pages

http://effinmotorworks.com/Effin_MPFI_swap.htm
http://www.angelfire.com/d20/hcivic88/dx-siwiring.html
http://www.geocities.com/c_rexboy/mpfi.html
http://www.geocities.com/teampimports/fuelinj.html

basically, you must do the wiring parts described in these write-ups. You cannot swap harnesses, sorry. You'll need to harvest plugs from your mpfi Integra harness, though. You'll also need the resistor box for your injectors and a OBD0 PR-4 ecu for a 90-91 Integra.

All this is assuming that your B18 is from a 90-91 Integra.... if it is from a '92 or later Integra, you've got additional wiring to do and you'll need a different ecu and won't need the resistor box. *EDIT* and maybe some other differences?

shift_wagovan · July 2007

Why can you not plug in the middle harness for a ef si? The plugs are the same?

jpciii · July 2007

I can't give you a technical answer as to why this is (maybe someone else can) but everyone on every site says the only workable option is to modify your dpfi harness. If it was as easy as swapping to a mpfi engine harness, it would have been figured out a looooonnngg time ago.

the motor i pulled outta the wagon was a pgfi, and the LS im gonna put into it is pgfi as well but the ecu plug ins are totally different im guessing due to the integra ecu is obd1 and the wagon is obd0 but im not too sure.....i still have to rebuild the motor before i put it into the wagon....ill take a few pics tomorrow of the empty bay and the block before i finish tearing it down to get it hot tanked

jeffsciv23 · August 2007

if your car came as a FWD then it is DPFI, you will need to do the wireing for the MPFI and then since your motor and ecu are OBD1 you will need to buy a obd0-obd1 conversion harness. as for the linkage i hear you will need to take the teg linkage and cut 2 3/8" out of the straightest section of both bars and wld it back together, and of course you will need mounts.

adamEFwagon · August 2007

ok ok i got it yeah the motor pulled was DPFI and the LS is MPFI, and i already knew about the mounts and linkage.....um the motor came with three brand new avid mounts for by the cam gears and tranny and the back i believe but they were for an EF hatch would they still work with the wagon?

by the way here is some pics

The car sits so messed up haha

Engine Bay

Old motor

LS tranny

Various pics of the motor

As you can see its pretty damn dirty and had a bad exhaust leak due to 2 exhaust manifold studs were broke in half. pretty much everything needs to be cleaned up

jeffsciv23 · August 2007

yeah those mounts will work

adamEFwagon · August 2007

alright good

adamEFwagon · August 2007

ok so now i got the head off, the pistons and crank pulled so its just a bare block....all i need to do now is get it to my neighbor and have it hot tanked but i dont know when this is going to happen, but hopefully it is real soon

adamEFwagon · August 2007

alright so i got the block to my neighbor to be all cleaned up and hopefully it will be back to me by tomorrow evening.....i will soon be ordering a clutch new shocks, tires, ES tuning muffler, 2.5" piping, and a gasket kit along with bearings

pLaYbOi · August 2007

Before you get the clutch, ditch the LS tranny and get a b16 tranny(shorter gears versus the long gears on LS trannies) it'll be worth the effort.

adamEFwagon · August 2007

i dont have any money for a b16 tranny unless i sell my integra seats and old motors

but anyways, i just got the block back today and hopefully the hed gets here by the end of the week

heres some pics

exhaust side

intake side

adamEFwagon · August 2007

well when we got the block back from the hot tank we noticed there was a deep scratch on the top so we got it milled down a six hundreth i believe which was a pain but it had to be done.

other than that, i got the whole block assembled today i am just waiting on the head and tranny
here is some pics

we just re-used the pistons but cleaned them up really good so they look nice

jpciii · August 2007

I hope you put new rings on them...

Looks like you are making good progress. 8)

adamEFwagon · August 2007

oh yeah definately new rings and new bearings and full gasket kit

jeffsciv23 · August 2007

looks good so far. i should be swapping my semi built GSR into my wagon in the next two weeks.

adamEFwagon · August 2007

thanks, and hell yeah that thing will haul ass i bet....i would have been done sooner if the motor wasnt so dirty and need a rebuild

adamEFwagon · August 2007

alright sorry it took so long i just had some shit to do today....the head and cams are in, just waiting on order of an exedy stage 2 clutch and a few other things, but here they are

adamEFwagon · September 2007

ok, a little update. i got my short shifter from fed-ex today and its pretty damn nice actually, it looks just like a B&M one for less than half the cost.

heres the pic......

hopefully i can get a little more money and start buying some more stuff

adamEFwagon · September 2007

alright, today i was bored as sh!t just sitting around doing nothing so i did a little thing haha

what you guys think? its not totally finished so dont start talking sh!t

freddogg509 · September 2007

that thing is hella bright....lol....looks pretty kool 8)

adamEFwagon · September 2007

haha thanks....it definately looks better on the motor....

i also put some washers on the back of my hood for that airflow idea and it looks pretty cool so far....

wagodizzle · September 2007

thats a really sweet valve cover job yo. so if its not finished yet, whats it going to be?

adamEFwagon · September 2007

well monday i am going to order everything else i need so hopefully it will be in the car and running in a week or 2. i think i might do a wire tuck as well since i washed the bay and its pretty clean to go with the clean motor, but im not too sure yet.

LS wagovan finally running.
