hey there!

i came across this kick *** site.. sorry if someone posted a topic like this before... but i searched high and low all over the forum before i posted this.

i have a 1991 gmc jimmy 2 door, v6 4.3l, that i plan on converting into a sedan delivery rodster kit car.
i plan on having suicide doors, fully shaved body, shaved tail gate, custom old 40's style front and rear bumpers. 33.0x21.5-15LT mickey thompson sportsman rear tires, and front runner tires for the front.

i plan on making on sick ride, just for cruising

if youve checked out the sedan delivery at rodster.com youll notice there ALOT more room inside the engine bay than a stock s10, the entire nose tilts forward giving you plenty of room to the engine

http://www.rodster.com/assets/owners/WeidnerSED231.jpg

that picture shows you how much room is freed up!

i have already purchased the twin turbos, and the turbo exhaust manifolds

the two turbos are made by mitsubishi and they are made for a v6 4.3liter gm engine, they are watercooled!

the turbos came off of a 4.3liter v6 that was used for HVAC purposes, so it was indoor, and run at constant rpm, so im guessing there is no shaftplay!

the original set up isnt intercooled, becuase its an indoor setup, but i plan on having a twin intercooler setup, unless someone thinks a single inter cooler is better?

i wanted to mount both turbos as far away from the engine as possible, and possibly fabricate 2 small side hood scoops to bring in fresh air for the turbo intake. and a long slender hoodvent that will run across the hood near the windshield to give it a wiper cowl effect, and it will be fully functional

i went out and bought braided oil lines, and a bunch of polished aluminum piping for the intercooler and turbo set up

ive bought a return nipple for the oil pan, and ive bought an extra water pump and an extra oil pump to get the fluids flowing more easilly, are the extra oil and water pumps nesesary? or should i just upgrade my stock ones to high output pumps?

later on when i have the money, i plan on supercharging it, but thats a whole other idea, imagine that, a twin turbo supercharged v6 4.3liter s10 running on 33.0x21.5-15LT rear tires! i plan on getting fender exhaust so you can hear this thing coming a mile away!

please excuse my stupid questions, but where does the pipe exiting the intercooler connect to? do i need a speacial intake manifold? shold i get a bored and smoothed throttle body?

and now for the answer to the question that i see alot of people who inqure about turboing there s10's are asked...

why not just drop in a v8?

well, becuase, here we go, ready for it? my gmc jimmy has 2500 ORIGINAL MILES never been driver garaged all its life!

this baby hasnt even had its first oil change!

im going to make sure it only gets synthetic oil the rest of its life! im guessing synthetic oil would be alot easier on the turbos too

and why an s10? well, i like the rodster sedan delivery alot! and the whole idea of a 33.0x21.5-15LT rear tire on a cruiser, and the sound of flowmasters is what i like,

im very tired right now
so i hope i didnt leave anything out, and also, please excuse any spelling or grammer errors, and i apoligize in advanced, some people are very ---- about grammer and spelling

i will be getting a camera within a month
so i will have pictures of everything up for you guys to see
thanks

You don't need to upgrade your oil or water pump. Couldn't hurt though.

The pipe exiting your intercooler connects to your intake manifold, throttle body, carb, whatever you have.

Good luck, seems like an interesting project.

hey jagojon3, can you show me how the pipe exiting the intercooler connects to the intake manifold, throttlebody, carb, or whatever i have
my engine is the 4.3L V6 OHV 12V FI Engine, with the circular air intake thingy, would i connect the pipe leaving the intercooler to the pipe connecting to the circulat air thingy? do i connect it at the red line as shown in this picture? (i got the picture off the internet)

sorry im stomped thanks for the good luck

hey there 90dx! i definatly thought this whole thing out out, i just got to work out the few small things that are left, i will have a camera in less than a month, and will have pictures of the car and all the stuff i bought. i read on another post that if you reuse all the factory sensors and put them in the right place that you dont have to worry about touching the ecu is this true? it would be awesome if you could dig up those links for me, i would be eternally grateful

i havent gotten as many replies as i thought i would i didnt think this forum was dead
i wished some moderators would reply :P

i edited my first post, and removed the website for the kit car, maybe people thought i was plugging the website?

anyways, i bought all my braided oil lines today, and i tapped the oil pan for the return, and i was ---- scared when i did it, but i need to know, where do i pull the oil lines from? do i pull one line and have a splitter to each turbo? or do i pull two seprate lines? also for the oil return, do i have two seprate oil returns? or am i good with just connecting the two returns into one line, and connecting it to the tap i just made today.

i need to know what size and kind of water lines to use, my twin turbos are also watercooled, where the hell do i pull the water from?
i figured ill need an aftermarket radiator with premade taps, have my feed line from taps at the bottom of the radiator, and return line to taps ontop of the radiator,

i got myself into a shithole here, and i hope it doesnt turn into a money pit

thanks

thanks alot random-strike
what do u think of a twin intercooler setup?
other than the oil pump, and water pump - which i plan on upgrading -and the other stuff associated with the turbo like the exhaust manifold, air box and such, would i be ok leaving everything else stock? like the ecu?
also, have i missed anything? i feel like im forgetting something
thanks for the quick reply, i hope i didnt come off as an *** in my last post

buk9tp

oh, the awesomeness

thanks a shitload random-strike

yeah, the first thing i realized is that i would need to get rid of the stock air box, and i was gonna install two cone air filters at the turbo inlets as far away from the engine as possible

so from what i understand, if i get higher lb/hr rated fuel injectors i would need to change my ecu, which is something i dont want to do.

or if i plug in all the proper sensors, in there proper places after the twin turbo install, and i install an upgraded fuel pump, would i be ok?

i like the awesomeness of a megasquirt, seems like i would go for one of those, and im pretty damn tech savvy enough to figure it out, and i love having things that look over complicated

but the FMU looks like the simplest soulution, but it only has one purpose... unlike the megasquirt. which i can use to control alot more stuff

so i think megasquirt it is, unless plugging in all the proper sensors, and upgrading the fuel pump would work

engine space really isnt an issue at all, check out what the engine bay will look like with a kit... this isnt the stock engine.. its a 350 i think... but u get the point




as far as intercooler, and turbo piping, is bigger piping ok? i was thinking it would look cool with 3" piping and i figure it would increase function

im guessing im going to go for a twin intercooler setup since space isnt really a restriction for me, ill have two long intercoolers where the fenders are supposed to be on the car... and ill install side hood scoops like i mentioned earlier to get better air flowing through the engine.

i searched the (inter) web high and low an could find anything on any 4.3l builds

thanks for this awesome website and all ur awesome advice
