turbo setup is not cheap. A street turbo setup will cost you atleast $25k when all said and done.

N2o is cheap.

Way too small. Dig up a 60-1, PSD turbo, HX40 or similar and that would be a good start for an L03 that's stock to lightly modded. Twins you could probably get away with a pair of K-car turbos but the Turbocoupe ones would likely be better. Just makes sure they are the same. The K-car turbos or the Turbocoupe turbos are probably easiest in regards to the fact they have internal wastegates saving you effort on that if you use the stock elbows. Some Grand National turbos are bigger but wouldn't be a terrible choice, even though you may want to cam up a bit first.

Get a bigger I/C that one is on the small order. You can get some 12X24X3" ones for under 200 each that would do.

You're going to need a "boost aware" ECU or some method of adding fuel. JMO get the 454 injectors or the 65lb/hr cop car injectors and an adjustable FPR (you can also convert yours over to an adjustable fairly easy if you have a drill and a MIG welder) and then tune em in for the extra power. You will need a bonnet and fuel pump for high pressure as well for any setup you do. I would encourage a Walbro 255lph pump personally or some thing similar.

I'd do some L98 shorties like the Corvette uses and run my turbo(s) off of extension pipes from that.

I highly recommend a turbo 305. I love mine!

you do need a few things but i think it can easily be done for under 3K. I hope you meant 2.5k and not 25k $.

here's a link to my build
https://www.thirdgen.org/forums/powe...gta-build.html

a way to program an ecu is a must. and the knowledge of how to do it.

DO YOUR RESEARCH and GOOD LUCK!

your out of ur mind

it will not cost anywere near that many here have built turbo systems for under 2500 bucks ,thats a far cry from 25k


that turbo in the add is way to small its just a t3 turbo, by itself it would never work, now a pair of t3s would work pretty good

just not a pair of the one in that add

is the car a tpi car or tbi

if u can weld u can build a nice set of twin turbo headers for under 150 bucks

fuel Injectors, aftermarket ecu, turbo or turbos, intercooler w/a or a/a , wastegate, blow off valve, hotside tubing, coldside tubing, engine upgrades,
chassis upgrades,drivetrain upgrades. all for $2500 ????

Could you post the many $2500 turbo system and their performance??

BANDITSBC

my ebay build for one. i think with the DFI it was about $3700. If i used megasquirt it'd be under $3000. I did add an intercooler that's not included in that price too.

lets say $3700
plus a turbonetics turbo $1000
I.C. $900
brand new 45# injectors $500

thats about $6100.00

lets build a motor
$800 383 block
$1700 afr heads
$1500 forged rotation
$500 misc gaskets pumps ect
thats $4500

$300 fuel pump
$1500 Transmission
$1700 rear end
thats $3500

$14,000 for a pretty sweet bulletproof build

He didn't say he wanted to run 9s

I'm happy with my $3000 build performance on a 200k mile stock 305. I'm planning upgrades as things break and money comes in.

I dont disagree with quality of NAME brand parts but it can be done on a budget and perform real well.

I didn't want to buy a bunch of expensive parts and realized they didn't compliment eachother. I wanted the experience on the cheap and UPGRADE as I can. It sure doesnt' take much to blow up an engine with 12# of boost if you don't know what your doing.

With ONLY $3000 spent on your build your leaving alot of stuff for chance of breaking. You probably have your boost set low for the time being ,well until your ready to break parts. So now you have a car that you feel sort of paranoid about what fun is that??

My point is to turbo a car everything needs to be built for the power level your going for. Once you start to build a decent turbo car ,you`ll be very surprise how fast you get to $25k. turbo cars are expensive to build and maintain ,they dont last forever. I know first hand my 87 gn built by duttweiler back in the mid 90`s probably needs $20k-$30k to get back in shape. The car was built to handle 1100 hp ,there is nothing stock on the car. On the upside it still ran 130 mph at the dragstrip on pump gas ,feathering the gas pedal the first 100` feet. but its tired. this how the engine looks after 15 years of racing and street driving.

im sure u have read the grenade thread on ttf.com
completelystock jy motor with the exception of a cam that cam out of a trash can that ran well into the 9,s with a air of grand national turbos that never blew up

a built motor will blow up all the same as a stock one if u dont know what ur doing

btw nice gn there if it only does 130 in the 1\4 id rip all that crap off i have friends with daily driven 9 second gns that will trap more then that for far less money and i mean far less

And how fast have you gone with this combo??? 76mm t6 should make around 1000hp .

project89

iTrader: (1)

i dont think the 76 will make it to 1000, most report that turbo will get to about 850-900 hp its an older tv series so older tech in the wheels, could have it ugraded to a new series 88mm wheel for about 2-250 bucks though.

i couldnt tel ya how fast it goes though i have it off the car since im switching to a pair of 60mm turbos mainly because this is a street car and with the placement for a t6 turbo being limited in a 3rdgen i have no room for an air filter.

living on the edge of a desert this isnt a good idea for a daily driven car, it gets really dusty here and we have alot of dirt and sand blowin around all the time

thanks its my next project car. I ran 130 mph at 15 psi of boost feathering the gas. If i dead hooked i would of run in the tens with ease.If i upped the boost and dead hooked 9`s would be no problem.

project89

iTrader: (1)

i missread ur post when i replied lol i went back and fixed it

not bad for only 15 psi though, but if u got rid of the twins and went back to a single u would prolly save a ton of money and run just as fast with a few pounds more boost

if ur trying to go into the 8s though the twins might be better

Drac0nic

Making 250-300hp with some boost is a far cry from an 1100hp stage engine; Besides this I will say there is NOTHING cheap about Buick GNs when you get past the mid-low 11s and have to start dipping into the engines really. I bet you could have built a full fledged SBC for way less than that Stage II cost and with a lot less custom parts/fab work etc. Just running an off the shelf single plane instead of that fabbed Hogans intake probably would save a few grand as an example. Certain things like the EFI would be a wash however.

Not touching my engine internally, I figured up everything I have used so far and came up to $3600. That includes a nice wideband O2 and boost gauge (something not mentioned in the $3100 above so his number is accurate as well if you factor that in, but you DO need a WBO2 so add that on!). My engine was old and tired (140k miles when I started boosting).

$3200 got me running 8.60's in the 1/8th

+$400 intercooler project

+$1500 transmission self build + converter that became nescessary 2 hrs after intercooling due to power increase

$5100 got me running 7.90's consistently (with a couple of 7.8x passes) (aka in the 12's)

Now the tired engine is really tired, so I will be spending a few more thousand to hopefully bring this car into the high 6 range. I lucked up on some engine components but I originally had the new engine build cost around $4500, plus a precision turbo $700. So another $5000 to shave off one more second in the 1/8th, but to do it in reliable fashion.

I am interested in doing the upgrade on a TV series turbo. Who does the 88mm wheel upgrade for $200 - $250? Is that a Turbonetics HP-88 wheel or Garrett wheel? Is that price including the machine work?

project89

iTrader: (1)

i belive its a garrett wheel,and was told the rice includes everything.

try contacting turbo daves i was told he was the one to talk to about doing the ugrade,though i belive theres another vendor or 2 on ttf that will also do it

the plan is to either restore current setup or swap in 406 dart sbc and use the current turbos,intercooler,motec 48, etc. I would have to add two more injectors. The BOP th400 would have to get a jw housing if i went the sbc route. OR anger the GN guys and throw in a 615ci NA pump gas engine and call it a day .

I agree sbc are cheaper to build than buick stage 2 v6. Sheet metal intakes
are expensive but work better than a cast intake manifolds. Some engine setups you have no choice but to use a sheet metal intake.

Dave was selling the Turbonetics HP-88 wheels alone for $350 the last time I checked. The Garrett wheel much be a lot cheaper.
