Winter Build gt47-88 383 lt1

I'm going to start up a build thread for my car this winter. I'm doing this so I can share ideas and information with everyone. Everyone's opinions are welcome as I am undecided on a few things and would like to here what you think. And I will post up pics of the progress throughout the build. Thanks, Miles.

Engine: 396 lt1
heads: I have brodix cnc'd IK210's.
intake: Edelebrock super vic w/ aarons intake elbow's elbow and fast 92mm TB
Cam: Comp custom grind.
Crank: Callies Dragon slayer
Rods: Callies ultra XD
Pistons: Diamond
Compression: 9.8:1
Transmission: Powerglide
Rearend: moser 12 bolt 3.42 gear
Turbo: Comp 91mm ball bearing billet wheel

I'm running homemade headers that I made with 2.5" crossover pipes.

Burkart Chassis 10pt cage

The car has a full Sphon suspension with QA1 shocks.


I'm sure there are a ton more things I forgot to add, but I will just add stuff as I go. And feel free to voice your input.

Run a taller gear. I'm a 3.54 with a T56. If I went auto I'd hit redline at 130mph-ish. I'm trapping almost that now and I'm just at 10psi, barely breathing on it. Your build sounds similar to mine, you'll like it.

Very nice, I am starting my turbo build as well. I already have a short block that has made a lot of power, so I can give you some ideas on the components you should consider(well I guess depending on what kind of power your looking for) as for crank and rods.. crank-callies dragonslayer will work very well, and rods get some nice callies.. h or I. As for heads I love AI heads so anything from them will work great with boost(200cc stockers, 212cc tfs,215tfs,) I also see a lot of guys with boost running the 227 afr heads and doing well with them, just only down side to those they require shaft mount rockers. Well good luck keep us updated!

That's weird that you are almost redlining at 130ish with a 3.54. I have a 3.90 gear in my car right now and trapped 135 crossing the line around 6800-7000rpm. My buddy has a big turbo lq9 car that traps 160 with the 3.42 gear. What rpm do you take your car up to? And thanks for your input.

I like AFR heads but they want an arm and a leg for them. I'm pretty partial to brodix but Im going to the IMIS show in Indy next weekend so I'm going to try and talk to a few head manufactures and get some input. I would also consider keeping the ones I have and sending them out to get ported. I was most likely gonna go with a callies/compstar crank and rods for my first choice but didn't know if there are any cheaper alternative out there that can hold up to the power. Thanks for your advice!

That's if I went auto. I'm a T56 right now. I'm going to 6500 and not even near redline when I go thru the traps. Probably depends on the converter slipping a lot also.

i have a 383, 8:1 compression, 210 afr competition heads (flow 322 cfm). twin turbo 72mm. i also have a th400 with some 3.25 gears on some 28" tires and they work awsome.
I would ether go with a 4l80e ( if you have enough money). or a th400. but i would deffinitly not go powerglide if i was you if you plan on driving it on the street.


how much cfm are the heads?
what compression are you going to be running?
how much boost do you plan to run?

Brodix says they flow 288@.600 lift. I'm planning on running 9:1 - 9.5:1 and running 25 pounds of boost. What 60ft times do you pull at the track?

Twin 40mm JGS wastegates are mounted.

Attachment 13135

Wow, is that thing sitting where the radiator was supposed to sit?

nice build.Im gonna keep an eye on this to see how it goes.
You cant go wrong with callies parts. thats whats in my lower end. Brodix makes some great heads.


Ive got a FTI Th400 and 3.45 rear gears. and Im swapping to a Turbonetics 78mm 1.15 a/r turbo on my 383 lt1 now. (was a novi 2000 supercharger before)

Yep! I have the radiator moved forward already but forgot to take pics.

Ive been kinda leaning towards a TH400, but Ive got a lot of friends that are PG fans that are trying to convince me to go that route.

Im also planning on running no intercooler. Been reading about the ebay ones and they get heat soaked real bad, and to buy a decent one is around 900 bones. Theres been a few people in my area getting away with it running e85, they claim their IAT's are normally around 20 degrees hotter than the temp out side. What are your guys thoughts?

Tons if guys over on turbofourms run eBay coolers. I'm putting one on and also plan a snow meth kit.

I also thermal coat everything. Nic industries make a great black heat disappating coating . For radiators, intercoolers, etc...

You really can't go wrong as long as you don't have a big pressure drop.

I've heard they work good on the street cruising but if you're at the track waiting in line to make a pass they can get heat soaked pretty easy, which wouldn't be a problem with you if your running water meth i guess. I got a couple buddies in the area with turbo car that have very different setups, One is a intercooled 402 with a gt47-88 and th400. The other is a non intercooled 370 with a gt55-94 and a powerglide. Both work well and are street driven to the track, raced, and driven back home. And both have ran the exact times. So im kinda torn between the two setups, I've been trying to pick the best from both.

I always wanted to do one of those N2o hallos on the intercooler... wouldnt that resolve the issues?

Mines so close to the radiator that the fan pulls air through the IC also. Might look into getting an IC and mount a fan to it.

YES !

popo, Yes thats a QUICK way to cool down a FMIC. but a waste for $40+ to fill a nitrous bottle just to spray down your fmic.
That $ would be better spend on a water / meth injection kit to help cool the intake charge. MOST people just use washer fluid as it contains alcohol also.


OP, you could always go air to water with a ice tank in the back also. As for Tranny I would deff. go th400 over a glide if you plan to do any kinda street driving / cruising.
Even then Im looking for a used gearvenders OD unit myself just to pick up some extra gear for long trips if ever needed.

I would love to have a gearvender, just not in my budget right now. Are all the ebay intercoolers pretty much the same? Iv'e seen a couple different companys selling them and they all look the same.

Ya a GV isnt in my budget right now either. Id like to put a T56 in my car but It would cost me just as much as a GV unit to "BUILT" a good t56.
So I'll stick with my FTI Th400

Yes all the ebay fmic's are basically the same. Find the size you want and then the best deal on price and shipping.

im running two water to air intercoolers, a ice box, a heat exchanger and a bosch pump.

Thats some racecar stuff right there lol.

not really this is a 100% street car. the heat exchanger makes it so you dont have to run ice all of the time

What did it dyno? And what were Iats with no ice?

this winter im rerouting my cold pipes to go over the radiator instead of going under. i also cut out both radiator supports and put them in so its a bolt in round tube ( so i can unbolt the radiator supports to pull the engine right out of the front). im also repowdercoating the whole engine and ceramic coating the exhaust and wraping the exhaust too. im painting the engine bay why everything is out. ( i figured i could paint the engine bay black with clearcoat for 30 or 40 bucks so i figured i better do it.) so all of these pics are from last year in a couple months it will look totally diffrent.

I'm not trying to hate, but IMO your car is a race car that gets driven on the street. I'm going to start a separate thread rather than hijack this one........

i have been on the dyno twice the first time is when there tunning it at tpis it put down 72x rwhp and on the dyno jet we could not get over 650 rwhp. i had it on 14 pai and 24 psi and both time were 650 rwhp. so i needed a new converter. i was blowing right threw it. so i ordered a yank eliminator 3500 converter and i will run 24 to 28 psi next year. its on the list of stuff to do over winter. and i have no idea on were th iat temp is. (i didnt tune it) and i havent hooked the scanner up yet for any
reason.

haha, I agree. Killer car but a race car driven on the street.

Moved the radiator support forward and finished the bumper cover mount.

Wow. That looks like it cam out pretty nice man!

Very nice work!!!

Thanks! I'm trying to keep it as clean and somewhat factory looking as possible.

Well your doing a great job.

Keep it up.

Nice build, I'll be following this one!

Got my Burkhart manual steering rack and battery relocation kit installed. I also made some hard line coolant lines. I'm looking for something to coat the inside of the coolant lines with to keep them from rusting, any ideas?
