Here we go....slow
Donor 4.8 - 400$ 2000ish 4l80e- 150$
and the subject at hand.

Had this 1999 z28 a4 for about 8 years and finally got the time and settled down to get the on3 76mm project going. It will probably be slow going due to cash restrictions but I feel I've got a decent start .shooting for 550 at the rear.

Probably have some odds and ends for sale in the classifieds from my old setup ( 4l60e 3600ss, full tsp true duals) .

This is a great site for newbs like me to get into this kinda thing and I am greatful for the knowledge you guys share.

But I digress just a fun project and I'll see if I can get the car running before February. Here's what I gotta do to the 4.8.

Pac 1218s
ls1 oil pan.
unsure of which intake to run but I'm
leaning toward my ls1 intake.
-cam at a later time ( already have jegs 228r dupe.)

feel free to chime in. Again this will probably be slow going :bs:

boost is so much fun.

Got the same build going minus the "subject" good luck!

You going to tune it as well? I picked up HP Tuner used and gonna give it a shot.

Which injectors and fuel system you thinking about?

defintely gonna have it tuned, id like frost to do it because he did my old mail order tune and it was spot on! But I can't justify trailering my ride to Virginia. So I'm up in the air about doing the hp tuners thing or spending the cash and getting it done somewhere within 150 miles.

walbro 450 in tank and 80 lb Siemens deka. know it looks ratty from the bent clip, but that was a pain in the a** to get off!

truckdoug 12-17-2017 08:27 PM

tuning my own stuff is pretty much the best part. instant gratification.

thedetroitkid 01-12-2018 06:39 PM

Ok got the deka 80's in the ls1 intake, waiting on some stuff to show up in the mail before I get rolling on the cam and valve spring install.

epfatboy 01-12-2018 07:21 PM

I did my cam/spring/trunnion last weekend. Flipped the engine instead of using dowels for lifters

Reused pan gasket but cover gasket too far gone.

You gonna shim the pump? I went with 3 washer (.140) shim. Also where you gonna plumb the Oil return? I decided on pan not cover.

thedetroitkid 01-12-2018 07:56 PM

+1 On flipping the motor, probably gonna do the melling high pressure, while it's on the stand.

Manley pushrods coming [ and length checker]
Cbm alignment tools for front and rear cover
Making my own spring tool and cylinder pressure filler ( thanks rural king)

not too sure on gapping the pump, I really hope I don't fry main bearings out romping on it. but I definitely was thinking return on the pan. Just trying to get the motor done up before I start on other stuff

thedetroitkid 02-13-2018 05:35 PM

Ok. So some progress, ended up pulling the heads and doing the Pac 1218s, the deka 80s are in my ls1 intake. Rollmaster timing set is on, looks like a nice piece ! Waiting on my cam degree wheel to come in from jegs so I can get all the timing set perfect. Then the melling high pressure can go on along with the water pump. Annnd the denmah kit with the 7875 from vs is on its way, pictures up soon. Yes my build is going slow. Just wanna get one thing done before i start another

thedetroitkid 02-28-2018 07:13 PM is getting there, spent time learning to degree my cam, which was spot on! And some initial confusion checking my pushrods. Ended up being just fine with the 7.4's. getting ready to figure my oil return drain on the pan in this spot

01ssreda4 03-01-2018 07:34 AM

I would recommend the turbo drain directly above the stock drain plug like in this pic

I have done exactly this a few times with success.

thedetroitkid 03-16-2018 04:20 PM

Well it's March and the car isn't running, oil galley plugs are on backorder from summit, that's the only thing holding me up with the motor. Ordered another walbro 450 , so the plan is have 2 in tank, and a regulator with boost reference, swedgelocked in-line of course! And I'm back in the air about having a/c so I'm looking around for some c6 manifolds. My bumper is notched and we're trying out this corroseal on the body inside the engine bay.

Lighting sucks

thedetroitkid 03-16-2018 04:40 PM

Stay tuned, oil return got welded on my pan a1, bmr k- member and yank 3600 for the 4l80 on the way.

thedetroitkid 04-08-2018 08:47 AM
This car is basically turning into a restomod. Realistically have it running next year. Picked up some decent c6 Corvette wheels for 300 bucks though. Getting going on some needed bodywork/ fixing rust. Pulled my dash, deleting the heat /ac. Got me a plas cutter for doing various things on the project.

thedetroitkid 04-08-2018 08:51 AM

I guess I could call it the " Rustomod"

thedetroitkid 12-14-2018 09:41 PM

Ok rustomod progress... engine bay is somewhat ready for paint in a few weeks after i get a hvlp gun hashed out. After deliberating the cost of buying a exhaust crossover vs building one, i decided to get the huron truck manifold, should be here within a few weeks. Started using corroseal on a bunch of parts and really doesn't work too bad.
Heres a lower a arm i used corroseal on

pulled the wiring harness out altogether which was a total pita. And engine bay almost has everything out of the way to prep a little and spray
Getting there!

and ready for the crossover to arrive and start mocking the engine in the k-member. Thisbhuild has taken me forever and a day and im glad i can finally dedicate some time.

looks good, and hello from near Bowling Green. If you need a dyno Tune I would reccomend Brian Turner and Dynotune Motorsports near Columbus. I am doing a similar build, Gen4 5.3, vs7875 on a huron speed kit.

thedetroitkid 01-05-2019 10:51 AM
