turbo install

AllanL · Post by **AllanL** » Mon Aug 04, 2008 10:17 pm

hello!
been here quite a while, but this is my first post.
i've seen some of you guys with FWD twin cam 4G63 turbo engines set up on RWD drivetrains.
regarding the turbo, i was wondering whether the install was as simple as rotating the turbo so that the turbo inlet faced the radiator and the hot side faced the firewall...
of course i have to re-plumb the coolant and oil lines of the turbo, and would have to have a custom-made exhaust manifold.
for any help or advice, thanks.
btw, the car is a dodge colt/colt galant 75...the current engine is a DOHC 4G63 NA with stock intake manifold, throttle body port relocated to face the radiator.
thanks again...

You can use the stock turbo manifold without problems if you can figure out how to use the internal wastegate. No custom manifold needed, but hey, if you can make one cheap, give it a shot.

Turning the turbo is easy, its running all the IC pipes, oil feeds / drains, water feeds / drains, inake pipe, mounting the MAF that gets time consuming.

lucky for you, this is actually what i'm working on today and i have it all figured out. i will post pictures later of what i did for all the lines.

ok i just got done with the oil drain heres what i did
1st i chopped the dsm oil drain tube and got rid of the accordian piece all together.

for one side i just left an inch of a stub sticking out for the pan side

for the turbo side i used the bent side that was normally for the pan side on a dsm setup

since i was probably going to run into some kinks, i picked up these anti kink hose sleeves (5/8)

here it is all nice and connected, it looks like it will clear the down pipe pretty nicely, but i think i will throw some exhaust wrap on it just incase.

heres the oil cooler line
i cut it right down the middle, added some fittings and flared. then i used a coupler to unite the 3 pieces together. on the turbo side i straightend out the line and on the new metal line i just bent it @ a 90 degree angle

heres how it looks mounted up

ok now this is what i came up with for my water pipe and lines.

i decided to use the truck water pump and water pipe. so i cut the pipe right after the bracket just so it would be kept into place in the water pump
note: i am not using a heater core

this is what i'll be using to tee off the water pipe for my lines.

this is the dsm water line that used to connect to the dsm water pipe. what i did here is just hacked off the last bend and angled the line more towards the engine.

this is a 3/8 tube with a 90 degree bend that i will use to connect to one of the tee fittings from behind the block to go around and under the intake to the t.b. nipple

heres a quick mock-up to show how the lines are going to be ran. just fyi i do plan on wrapping some heat wrap on crucial areas.
the inside water line will point straight forward and connect to the water neck.

here it is, fitted

heres the inside line to the water neck fitted
note: i slightly angled the tip upward so the hose would have less of a chance of crimping

last but not least and unfinished the t.b. line. this is just to show how it will go around and under.
i do plan on circular loop for the tip on this line so it can reach the t.b. nipple as close as possible. to hold the pipe in place i will use insulated 3/8 wire holders alongside the block.

i think im going to call it a day for now, but i hope this has helped somewhat

thank you very much, been of great help.

by the way, how exactly can i 'clock' the turbo housing?

points to any link will be helpful.

thanks again.

to be honest with you i didnt really need to clock the compressor housing at all, i was fortunate enough to barely clear anything but it cleared at a safe distance.

the only thing i ran into right after i posted the pics for you is the stock wastegate but i figured that out already i just carefully chisled the bracket right behind the actuator and it came completely off. no i was able to get any angle i wanted on the actuator and linkage.
as a matter of fact let me take some snap shots for you so you can see what i mean, although its not complete but atleast you can see where im going with this

IDriftNaked · Post by **IDriftNaked** » Tue Aug 05, 2008 11:24 pm

the outcome was that gap that you see right between the actuator and bracket but atleast i connected a to b. so what i have planned is to wedge in a melon slice shaped spacer and tack weld it in.

another benefit of chisling off the bracket is that you can clock it so the nipple can face any way that you want it to

This is great! I'll be saving this thread to my pickup build.

When the wastegate actuator opens up the wastegate in the turbo is supposed to open all the way correct? Having problems getting the actuator to travel far enough to open it all the way. Any tips or suggestions? Thanks

Post by **DJpowerHaus** » Sat Sep 13, 2008 9:49 pm

I don't think they need to open all the way. As long as it can bleed off the back pressure, it should be work. Might boost creep. A test drive will be the only way to tell. Get that done and driving.

lol just make an externally gated o2 housing and save yourselves all the troubles of internal gate shit.

does this mean your giving us all external waste gate for christmas

haha yea really.

I may just go with a externally gated o2 when the time comes to finnally put it in if I dont have this internal gate figured out by then.
