Final discision on whether to get 190 or 255lph.

[nightspeed87]

My car is in a motor swap and rebuild process and its down and therefore I have very little money to spend ( also since It needs a new tie rod, and cv axle and new struts im limited on spending )

But ive been thinking of what pump I should put since I am going to upgrade the pump and do the rewire mod while its down... Now I dont have a afpr and I wont have the money to get one for at least a couple months or more so I was kind of iffy about getting a 255. Despite that I would rather get a pump where Id only have to go in there once, and actually I was even thinking about getting the supra pump since it pushes a little more, and from what im hearing its quieter because I DO NOT want a loud pump.
Thats another reason I was leaning towards the 190 because I hear there quieter, and for my set up right now will be more than enough and will work fine without a afpr.

But If I had a afpr Id gone and get the supra pump, but since I dont have that, and because I dont want fpr over run is why I was just going to suck it up and get a 190lph with all said even though I know its not the choice of most ppl. but if you were me on a low budget would you just live and be happy with a 190 and not worry about the afpr, or would you get the 255 or supra pump and deal with fpr over run for several months until buying a afpr was possible?

( And how bad is fpr over run anyways... Doesnt seem like something Id want to deal with
but from the experienced what is your views of it )

I checked that lightningmotorsports.com site, and they don't even list a 190 pump for DSM's. I'm 99% positive, as well, that Walbro doesn't make a High Pressure 190, or at least I've never seen one on any other vendor's site before.

I know there is a 255 HP pump, I have never heard of a 190 HP either.

Huh??? Well what I ordered said walbro 190lph hp fuel pump 90-94 eclipse fwd.....


Check this out, this is exactly what I got, and it gives an option on which one you want
and I clicked where it said walbro 190lph HP, ( and it indicated plus 5$ for the hp version).....

Tell me your opinions, especially on this whole hp thing, since you say you guys havent heard of it for the 190s.

Yea like the last month of me driving it as an n.t I only filled it up with 93 so that it would already be coursing through its vains , and Yea i would like to see that diagram if its possible you could mail it to me on here or my aol email address is [email protected] because I am also just adding the wires myself I wouldnt have the time,money to pay someone, or do it myself patience to install a whole new wiring harness.
but any info You have and could email to would be appreciated. I didnt want to start a thread on this because a lot of ppl probly wouldnt attempt the swap and just buy gst or gsx from the get go,
I already have a couple print outs on info on the swap and what wires to run, but how and where they should be run is still what I need to know.
The ecu I have is a 1990 ecu and I am pondering will this work right in my 93, I know the instrument cluster will have problems... Currently Im searching for a 91 eprom to run it with.... What yr motor did you install, and what yr ecu.? Has your car had any problems since your swap, anything tips or advice to make it easier, or anything that was difficult?

I used a 91' 6 bolt engine and the ecu from the same car. Do you have a spare wiring harness or can you get ahold of one from a turbo car? I can taylor a diagram for you. You'll need the fuel press. reg w/ plug and wires runinng to ecu, wastegate reg w/ plug and wires, maf sensor and plug w/ wires, resistor pack and plug with wires cust about 6 inches long and the knock sensor plug and wires. The hardess part is wiring the resisitor pack and that pretty easy with the way I spliced it in. And everything is easier to wire with the engine out. I'll hit you up with a email on where to wire everything. Just try to find a wiring harness from a turbo car so you will have the ecu pins already installed on the wires with the plugs needed.

ok that helped a little.... I dont have a gst wiring harness at all, I was just retaining n/t harness.....
I do have the inj resistor pack, 7th wire for mass, knock sensor pigtail, but I dont have the wastegate solenoid wire, and I dont have a gst fuel pressure reg/ I hear I can keep the n/ts and it provides 10 more psi.
Im going to try to go to the junkyards again but last weekend I went to the junkyard and all the dsm cars were n/ts.... Can i buy the ecu pins seperatly in case I cant find any?
I know were the pins go though, but to be honest i havent even opened my ecu yet to see what it looks like in there..... Im not very wire/electrical literate, despite I can hook up all kind of gauges, and systems and tvs in my friends cars but I just never liked messing with wires...... Did you use the stock wires for each thing you had to wire back, of use the pins with new wire you bought???? And if you used new wire what kind ( what gauge wire was it ?)

Oh and that email of the wire diagram will be much appreciated.... And if you could even include some of your own tips/ and instructions on how you did it that would help also..... thanks.

I pulled the wires I needed from a wiring harnesses from the donar car I had and grafted them into my n/t harness to make it a turbo harness. You will need the plugs for everything at the very least. I sent you a pm let me know what else you need.

Yea i just cut the wires from the gst harness from the doner car that I needed
and was going to solder them back together....
I forgot to get the wastegate solenoid wire and the plug for the wastegate solenoid though ( I think its the plug that sits on top of air can ..... What should I do about that..?
Did you keep your n/t tranny? Im in a debate whether to keep or ditch it....
I have the gst 6bolt tranny that came with the motor also, but ive read i will need to change to a 90s shifter to run that tranny.... My n/t tranny already has a stage 2 clutch in it..... ( n/t tranny i hear also has lower gear ratios.... )
I dont know what to do about tranny either...
( Remind me to buy a gst nxt time instead of converting to one. )

I kept the n/t trans. Also keep your n/t motor handy you'll want to swap some parts from it with the turbo engine. Like the cam angle sensor and such. I may have some of the plugs and wires left over from the harness I used. I'll see what I can come up with when I get it complete just pay for shipping and you can have the harness I make for you. It will be labeled where the wires go and to what pin in the ecu they go. As far as the resistor pack just split open you n/t harness at the firewall between the 2 mounting brackets and you will see where 4 wires are spliced into 1 wire cut out the splice run the red or white wire from the injector pack to the 1 wire coming rom the right side firewall direction. The rest of the wires splice color for color. All done with that the mount the res. pack to firewall.

hmm... in a thread about this swap it was saying splice the inj resistor pack wire to the yellow wire coming from the injector plug harnesses..... So your saying through the wire to a wire with 4 wires running into on the fire wall and this works also?
Is it located by the steering wheel colume, or under the clutch fuild or something?
Maybe later on I should take down your phone number so when Im trying to do the wiring you maybe can coach me through a little of it, and yea i would pay for shipping if you could make something I can use for the pins......

I sold my n/t motor to the guy doin the swap so hes charging me basically nothing to drop the turbo motor in, and I payed him to build it up... I just have to do the wiring myself ( the extra wires, hes running all the other wires to the motor for me, I just have to add the turbo wires needed )

But he will let me take what I need of the n/t.... Im already taking the cam angle thing...
Also the 90s motors came with a bunch of transitor and egr stuff thats different from the 91 and up motors
and Im doing away with all egr stuff, and he has a transitor from a 91 and up model laying around and he has a 91 eprom ecu that im trying to get him to sell me...
