I've been out and away from the car for the past few months, but finally had some time to do some work over the weekend.

I started working on my new manifold set up. all 1.75" 304SS. I was able to get 3 of the 4 driver's side manifold cut, fit and tacked in place. I hope to finish the last runner next weekend and get it all tigged up shortly after that.

Also, i recently got one of my last shipment of materials in for the exhaust. All 304SS as well. Stepping up to 3.5" from the 3" i had on the last setup. I'm going to make a clone of my Trust DD catback, which was 3" to dual 2.5" that opened up to dual 3.5" tips. This time, i'm going 3.5" to dual 3" to dual 3.5" tips.

Here's what i've got:
7' of 3.5" straight polished (4' not pictured, on back order)
5' of 3.5" oval tubing
(4) 3" 90* bends
4' of 3" straight tubing
Vibrant 3.5" race muffler
3.5" stainless flex section
2.5" stainless flex section
(3) 3.5" stainless vband kits
(2) 3" > 3.5" transitions

hopefully more to come in the next few weeks

Man, i have not updated this in a while

I have been able to make some progress just recently on the fabrication of new manifolds. Right now i only have the driver side in the works. I've changed the layout from one of my previous posts. Runners are fully welded, just need to do the collectors and then weld the runners to the head flange. FIrst big SS TIG project, so far so good.

while i continue to work on the new manifolds i need to address cooling issues i've been having.

I posted a fiberglass vented hood last year but had several modifications that needed to be done in order for it work.

with my previous setup, mainly the Taurus fan, i had to cut out my radiator core support and move the radiator forward 4+ inches. This time around, i wanted the support back in place so it didn't look so hacked. I welded in the replacement core support and worked on making new mounts for the radiator to tuck up under the support.

To do this, i started by making a alum shroud and used a Volvo 850 e-fan, pretty much the same motor as the Taurus fan but 3" thinner which allowed me to move it back towards the engine.

made some new mounts as well. lower mounts not pictured.

With the fan mounted, wanted to make some coolant hard pipes to get rid of cut up radiator hoses. silicon couplers and 1.75" aluminum tubing.

After that, i prepped the engine bay to paint the newly installed core support and welded a few bolt holes shut

Along with battling the high coolant temps, i was consistently having 250* oil temps, 40* over coolant temps just from daily driving. I decided to add an oil cooler setup and a new power steering cooler.

B&M 23 row super cooler 70273
Derale 180* oil thermostat
Derale powersteering cooler
Mishimoto oil cooler adapter for the Pontiac GTO oil pan (Improved Racing didn't have the GTO adapter available any longer)
assortment of Jegs -10an fittings and nylon braided line

mounted the thermostat on the fender well side of the driver frame rail. Plenty of wheel/tire clearance, plus will be protected when the fender liner goes back in.

then i fabbed up a bracket to mount the cooler. cut a piece of 1.5 x 1.5 x .125 aluminum angle. going to brace a little more though. Mounting it right below the driver headlight behind the lower vent below the turn signal on the 91-94 bumper.

I'm currently working on the lines right now, but need a few extra fittings and hope to have this buttoned up in the next couple weeks.

More to come!

I would come check out the updates you have made but I moved across the country.

What welder are you using? Looking to pick one up myself that I can use in my garage.

ka-titties · 10-26-2016, 06:55 AM

good work man.

are you using a gas lens on your TIG for those stainless welds? if not, I highly suggest one. check out the Furick cup

Hey man, where did you end up? i'm guessing you moved this summer? after graduation?

Thanks man! yeah i have an assortment of gas lenses. i know my stainless welds are a little hot, just haven't been able to find the sweet spot yet. currently i'm at 35-40 amps and 25cfh with .035 308 filler rod on those welds. by the time i finish the other manifold, crossover, and exhaust, i might have it down.....

Smartone · 10-26-2016, 08:45 PM

Graduated and now I am now in Seattle! Building another 300ZX LS car but this time building it for Road Race.

91 240 · 05-12-2018, 07:36 AM

Damn I've been away for a while. I lot has happened since my last update. Moved from a house to an apartment and finally to our new house back in September.

I've actually done a lot lately, but i dont have too much to show for it. Some out of necessity and other self inflicted. Oh well

I'll start with more self inflicted first, as that's more fun to talk about.

Starting simple. I saw a shift knob I fell in love with years ago but found out it had been discontinued. I had asked if they could do a one off but they no longer had the prints for it, so I said what the hell I'll get it anyway. Turns out they sell blank shift pattern discs and I found a local engraving company to copy the pattern. It's a MGW Gripper knob to go with my MGW short shifter. Here's the original MGW piece

Here's the new one with the piece i had made locally....pretty damn good!!!!

Next i got a set of JDM 180sx Chuki side skirts. I've been eyeing these for a while but finally pulled the trigger when a friend decided to sell his set locally.

Not a great pic.....

Upgraded from the stock 78mm throttle body to a 92mm

My previous Suspension Techniques sway bar was actually rubbing on my GTO oil pan ever so slightly, so i ordered a GK Tech sway bar for almost 3" of more clearance

after much thought, i decided to swap out my MasterPower T76 turbo for an On3 Perforance Billet 7675. Better flowing than the MP76, very comparable to the Precision 7675 at half the price, and the LS and Mustang guys have been giving props

I bumped up from my 80lb injectors to a set of 95lb/1000cc injectors. I'm planning to convert to E85/Flex Fuel later in the year and took the plunge now:

Now for things that needed to be done.....
1. redoing the turbo setup for the new hood
2. cooling issues....this thing still gets hotter than i am comfortable with

Ended up cutting the new hood for Aerocatch latches

Sad day getting it towed from the old house to the apartment

New hotside ended up being modified LS truck manifolds due to timing, i just wanted to get it running while i continued to work on my tubular manifolds. Welded some stainless tubing and vbands to the cast iron manifolds. Had them coated and wrapped the stainless portion

2.5" 304SS crossover with flex section and used a exhaust cutout as the 2>1 merge

Used a Turboflanges.com 2.5" round to T4 304SS flange

Added a VS Racing 44mm wastegate and dump tube

Made a 3.5" downpipe that transitioned to 3.5" oval for ground clearance. It's only complete to the transmission for now. Plans will be to copy my Greddy DD layout and go from 3.5" > dual 3" > 3.5" tips (Greddy DD was 3" > dual 2.5" > 3.5" tips)

Shitty cell phone vid at idle

Next i went on to fluid cooling, in addition to the oil cooler i added earlier

Derale 4 row powersteering cooler mounted to upper radiator support

And finally on to radiator/cooling which is still in the works
for now the same Griffin 24x16x3 (19x15.5x2.5 core) radiator but with a 16" Spal Extreme fan (2500cfm)

Converted an Ebay aluminum overflow tank to a custom surge tank. Actually modifying this for more capacity and to be self bleeding.

Made a couple of block off plates to fill the gaps around the radiator and lower core support

I also have a LRB undertray to help with airflow while driving

http://lrbspeed.com/product/s13-undertray/

Cooling at idle is still an issue, so i'm making a fiberglass shroud for the Spal fan as a last ditch effor before i splurge for a slightly bigger radiator.
made a form based on the dimensions of the core and the fan

wrapped in a $5 Wal Mart polyester blanket

then a couple layers of fiberglass fabric and resin

Need to trim, prep, and paint after it's fully cured to see how it really works.

Cooling has been the thorn in my side for the last 2+ years. I have a pair of N1 style ducts that i have available but i want to keep that as a last resort. I'm seriously considering an Origin Stream or VS racing front bumper so i'd like to have cooling down before having to modify the new bumper.

Hopefully i have more promising updates soon!

91 240 · 10-28-2020, 09:43 PM

So yet again another long gap between updates. This is going to have a few changes over the past 2 years.

I ditched my entire cooling setup and started over, however looking back i might have actually ended up being a dead Optima battery. It would hold a charge but as it heated up it would slowing start dropping. Oh well, new battery and these changes have been good so far.

Ended up with a slightly large Griffin Dual Pass radiator with Derale dual fans. I had to notch about 1/2" out of one of the end tanks to get it to fit within the frame rails.

I had to push the radiator as far forward as i could, which meant relocating the headlight motors using the Auto-Collect Storm brackets

With the larger radiator/fan combo, i had to redo my turbo setup. I had to pull it in about 2" closer to the motor to clear the fan shroud. Stuck with the same 2.5" stainless

Ditched my old ebay FMIC for a Treadstone TR1245 31x12.5x4.5

Then made some new IC piping. Got some good practice on my aluminum welding.

From there I wanted to finish my exhaust. I used my Trust DD and made a jig to step up the piping size.

Trust DD is 3" > two 2.5" > two 3.5" tips.
My exhaust is 3.5" > two 3" > two 3.5 > tips using a Vibrant Race Muffler

Little idle clip
https://youtu.be/lyLGZJe_ceA

I did a little suspension work. Finally added the SPL mono bearings i've had sitting for a while. Z32 uprights, lower shock bearings as well as all 3 rear arm bearings.

Little cleaning, before and after

Got some new rear wheels and tires, same style just went 17x10.5 +27 with 275/40's to 18x10 +40 with 285/35's. The 17's were too wide and didn't want to try pulling the fenders that much. With the 18's I ended up only having to do a mild roll/pull...maybe 1/2". Gained almost 1.5" of suspension travel

Before

During

After

I just finished up my turbo intake piping. Needed to get creative with some pie cuts to get it where i needed it. This took about 6 hours of welding

I should be finishing up my front suspension this weekend. Koni yellows to replace the KYB AGX's i had with the Ground Control coilovers. Adding T3 camber plates and their upper spring hats

Got a new bumper that's going to need some work to fit. VIS Racing knock off of the Version Select V4

Pretty much how it sits right now.

I have a few more little things to wrap up before i'm ready to have it tuned again. Hopefully something in the next couple of months.
