I am just curious if someone could tell me what is so great about the Racetronix kit over just installing a Walbro/Bosch intank pump yourself. I mean you need to cut the hole or drop the tank to do both anyways. Also from the instructions I found for installing a pump @ http://www.taekwondoplus.org/z28/fuelpump.html it doesnt look that hard. Can someone please enlighten me on this?

One more final question is how come people say that the 28 lb injectors are good for over 450 rwhp yet I was told in the FI section that I needed bigger injectors before installing my Turbo Tech T60-1 kit? See link below for hp guess on injectors.

The ractronic kit is plug and play. Where the the walbro pump itself needs some fabrication to install. BTW I think the racetronic kit uses a walbro pump but it also has all the hoses and wiring adapters to plug right in.
Hows the turbo coming? Can`t wait to have another turbo guy local to terrorize people. It`s alot of work by myself. Your 28lb injectors could probly handle 450hp but they would be maxed hardcore. Id atleast go with 38lb injectors.

 

How much fabrication is needed to install an intank by yourself?? From the link I listed it didnt look like too much was involved?

I have the kit in the garage. Just collecting parts for the motor that will go in at the same time. Just got my H-beams in the mail today. Cant wait to get home and check them out. Slowly but surely the project moves along.

 

Glad to hear it`s coming along well. I don`t think theres much fabricating on the 98s basicly just splicing some wires to convert from the stock elec. plug to the plug for the walbro. next just remove the old pump and caseing then use hose camps to secure the new pump to the assembly.

 

Thats what I thought it consisted of. I just cant justify buying the Racetronix kit. Thanks for the input.

I also took your suggestion about Jethot coating the turbo manifold log and will be sending it out to get the 2000 coating. I just dont want to be melting wire loom like you said yours was doing. By the way do you have a EGT gauge on your log?

 

No i was going to put it in the log but the probe on the sensor is to long for the 2 1/4 pipe so i put it right after the down pipe by the o2 sensor. Ya the melting wire loom thing sucks, I need to pull mine off soon and get it coated. I don`t know if you did this already but One thing to check on the log is make sure the ports on the log line up with the ports on the head. I did a simple port matching with a die grinder. also another flow restriction on our log is where they welded the primarys on to the log itself mine looked like hell the holes cut in the log where the primarys go in were at least a half inch smaller then the primarys themselves. just look down each primary you`ll see what i mean. Another restriction is where the log bolts on to the turbo. If you look at the log the opening is round, then look at the inlet on the turbo exhaust housing it`s square. When you bolt the two together the square inlet on the turbo blocks a half inch on each side of the outlet on the log. I took my die grinder and ground two half moon shapes in the turbine housing where it was blocking flow. Sorry so long just trying to give you some tips to get the most flow out of the kit.

 

The Racetronix set up will support 50-100 more horsepower due to the fact that in the kit , they have the necessary accesories to rewire your fuel pump to get more voltage to it , thus pumping more fuel . The Walbro GSS340 pump by itself with the install kit is basically plug n play also , you just have to splice the fuel pump wire harness which couldn't be easier . There might be some slight fabrication required to fit the pump without it moving around (cushion it) , I had to drill some holes in the bottom of the sending unit when I did it in my 99 . I got mine from www.neweraperformanceparts.com for $99 , probably the best deal out there .

 

the 98s have the metal tank and is much easier to put the pump(or two) in.

heres a link to my fuel system,

.. easy as pie.
the 'rewiring' is just a 30 amp automotive relay and some 12 ga wire going to the positive acessory terminal in the engine bay and a 25A fuse, set you back about $8 at radio shack

use the old ground for the pump.. run the old power wire (grey) into the switch side ofthe relay, ground the relay and run the wire from the acessory terminal back down the trans tunnel, into the +12 side of the relay out the remaining terminal to the pos. side of the pump. i tie wraped the relay to the wiring harness.

 

I was looking at the first link that I gave in my first post trying to understand the wiring to the pump. I see in there that there was an adapter that plugged into the pump and then connected with another harness which looked like it may be the factory harness. Is this correct? Does the Walbro pump come with a harness that plugs into the pump then connects to the stock harness?

Mightmouse - where does the 25 amp fuse go? Do you run it with an inline holder on the 12ga wire? Also where did you ground the relay? Can you splice into the ground that goes to the pump?

Thanks for the replies guys.

 

I just used a inline fuse like you said and my relay is just grounded to the body of the car with a short piece of wire. When you buy just the walbro pump i don`t think it comes with the harness but the racetronic plug and play kit does.

 

Well take a look at this pic:
http://www.taekwondoplus.org/z28/walbro01.jpg

There is a plug that is going into the pump then connecting to another plug that has black and grey wire going into it. Where would I get this plug? And if the pump doesnt come with the plug how do you connect the wires that go into the pump?

 

the pump comes with a new plug pigtail, you cut the wires that were connected to the old one, and crimp the provided plug to them, and plug in the pump.

you can go to any part of the chassis for ground..

 

Would everyone agree that the Walbro GSS340 intank pump be good enough for the Turbo Tech T60-1 kit with the upgrade to a T76 down the road?

 

It`s not what your running it`s how much power your making. Your stock pump would handle a TTI kit with a 76 if you were only running 3psi. That pump with a hot wire kit will handle a little under 600rwhp according to racetronics. But I like my engine NOT blown up so i would not go any further then 550rwhp after that, twin intanks new feed line and new fuel rails would be the safest way to go. But thats just my opinion. Call me paranoid.
