1point3liter's Twin Turbo LSX FD

I knew bits and pieces of the story from Speedfap over the years, but this thread rocks.

And your TIG welds are killer for someone just starting.

Speedfap, lol.

Thanks for the compliment. I read an ebook, did some interweb reading and also found a couple 1.5 hour TIG training videos on a torrent site. The training videos and weldingtipsandtricks on YouTube made all the difference.

I'm also thinking about selling my Aeromotive A1000 and pump controller. A set of Bosche 044's will more or less be a wash cost wise and resolve my fuel supply limitations

Were you having some sort of fuel problem with the A1000? PM me a price for the controller, I already have an A1000 Pump.

On a FI car, an A1000 is good for around 650 - 700rw. My car put down 655rw and started going lean towards the end of the pull.
I'm pretty sure it was the pressure dropping off as I have 96# injectors and my duty cycle is very low.

For the record again, my name has nothing to do with a ferrari.   

I think you'll be happy with the direction you're going.  Glad I could save you some time deciding what to do with the front end business.  I'm excited to see the end result.  Our setups should be similar I think.  On the fuel pump, just get a Magnafuel 4303 and be done with it.  It'll be one more thing our setups have in common.   

Your welds look great.  Especially the aluminum.

I was wondering how long it would take you to say something about that.

I'd been planning for a couple years to buy a similar radiator and cut it down to 13.5" tall so it would sit under the hood latch. I've had a hard time with the idea of cutting the brace out. Finally i just came to the conclusion that it needs to go. With it removed there's better air flow and I can fit a taller radiator. I also did enough cutting up near the headlights to allow 1.5" end tanks (27"total width).

Before i saw you and zbrown using the howe, i was planning to buy a cheap griffen double pass 27.5" wide radiator off amazon and just narrow the endtanks.  Once I saw how cheap the custom howe radiators are and how well it was working for zbrown with my same water pump, i was sold.

I will admit that my replacement support brace is your idea with some adjustments. I'm probably going to remake it now that my welding abilities have improved and extend it further down onto the frame rails.

Your welds look great.  Especially the aluminum.

Thank you sir.

How's progress with your hotside coming along? Did you finish the crossover?

Is that the same pump Nick is running?

I'm pretty much sold on dual external bosche 044's. They are known for being OEM reliable and I'll mostly be riding around at a power level that one pump can support. I'm also thinking the magnaflow may have trouble fitting next to the tank in place of my aeromotive.

Nice work.

You'll see a big 'ol update in my thread in about a week I hope.  I want to finish one thing first.

Yep.  I was going to do dual 044's in tank.

  Problem is, you still have 2 pumps which scares me unless you have a fail safe with your ECU to drop boost and timing if one fails.  044 cost a piece is like $200, so $400 for a pair.  The Magnafuel is $485 on Summit and Blake says you can get it cheaper.  Plus it has a higher headroom and it completely rebuildable if needed.  And it's not all that big.  If you already had a 044, I could possibly see getting another one, but since you're starting from scratch, might as well go with the big boy.

Looks good man, that radiator will work well for you i promise

Alright guys, I'm trying to be better about posting updates.  Here's the latest.

My Howe radiator arrived. I originally planned to have the inlets and outlets on the driver's side as shown here, but decided to turn it upside down as you will see later.


I made some radiator mounts. I designed them to maximize space for intercooler piping.
They bolt to the bottom of the frame rails and use rubber spacers. The are very sturdy and I will be adding upper mounts too later on.

They are so wide on the radiator because i originally made different brackets, tacked them, then decided i wasn't happy with the solution.
Anyway, i wanted to cover up the old tack marks. Disregard my shakey welding there. I didnt really have any room to prop my hand.



...and the radiator mounted.  Note that with a little modification to the tubular brace, I have room for an AC condenser. That will be future project.
I had to trim the shroud mount off the front of the radiator.. im surprised how well the cut and filing turned out.. you can't even tell it was there.



OK..... so you may have noticed the turbo location in a previous pic...
Well, I've always wanted to build my own turbo setup, i just didnt have the welding ability..
After a month or so behind the mask, i'm feeling pretty confident and decided to jump in.
I've decided on truck manifolds for now. They'll look a lot nicer once they are coated.



I bought a lightly used Precision 7675 with cast wheel.  My plan is to place the turbo in front of the motor but off set towards the driver's side.
This allows a 4" intake to be run under the frame rail to the stock driver's side oil cooler location.

This is a piece of 4" aluminum I'm using for mock up.
What i'm showing here is that I've found there's enough room to run a 3.5" - 4" downpipe between the block, motor mount, and manifold/crossover.
It'll be a bit tricky, but i'm pretty confident i can make it work with no rattling. The wastegate will sit centered below the turbo. If everything goes as I plan, all the hot side piping will be low in the engine bay and spark plug changes will be a 10 minute affair. I will also have room for an AC compressor.


I bought a cts-v waterpump and balancer to buy additional real estate in front of the motor. CTSV's use the vette style belt location which is 3/4 closer to the motor.
This water pump also moves the outlet toward the driver's side which gives me more room for my IC pipe will will now come up from the pass side.


yea, the water pump is pretty much even with the TB.


new aprox placement of the turbo. This is still with the fbody style balancer installed.  The water pump outlet will clear the turbine housing, the angle makes it look like it wont.



I have 2.5" of space for a radiator fan without pushing down on the turbo blanket.
This will accommodate a  flex-a-lite 420 fan shroud setup, but i'm going to try a volvo fan i pulled from the junk yard for starters.
The volvo fan is considered to be more or less the same as a tauras fan just packaged a bit differently.
It'll be a tight fit on the core, but with a custom offset shroud and some trimming, i think it'll work perfectly.
It'll buy me room on the driver's side for the turbo, move more air than the flex-a-lite setup, and cost a lot less.



I also did a quick clean up on some of my rear suspension parts. I hope to have the rear end in the car soon.

man, my engine bay is really overdue for a re-cleaning.

[FasTruckMonkey]

Thats a good start!

I like it, looking forward to seeing this one come together.
