So the wastegate just needs to be ran off the J-pipe and the actuator will open automaically for sure at 8 psi.

As long as you don't have boost creep.

TimG, thanks man, another question, how can I tell how the wastegate's condition is. I know it is really hard to pull by hand and I am a strong kid. It has a loud suction with the pull but, around here I don't know any place that has a turbo shop.

Hook up some compressed air to a line that is connected to the nipple of the gate. Regulate the pressure (with an external regulator) and allow the pressure in until the gate moves.

i got a guestion if you put the tb pistons in the n/t block wit the proper fuel setup and computer would you be able to run more than 10 psi

TimG said:

He drives a 1g n/t. You can't call garrett. But if you set up the wastegate directly up to the j-pipe, the stock gate will open at 8psi as long as you don't creep.

my nt is/was a 4g63....


more people should tuerbo the 4g63 nt..
dont try to build an exact 4g63turbo copy,..if u have high compression,use low boost..works great for me

Yes, lower compression pistons are bolt in as long as the wrist pins and the models are the same size. You can run more than 10 pounds of boost with lower compression pistons, I would just make sure your rings stay good.

And TimG if I do that, how do will I know if the actuator is fully open @ 8 psi?

Set up the regulator on the compressed air at 8psi (not a built-in to the compressor crappy one, but get an external one which will be in series with the compressor line) and regulate the pressure to 8psi. Hook it up and see if the arm fully extends.

Just try it and you'll understand. It's not rocket science.

Alright man, cool cool, are you running the MAF-T with a GM MAF? I didn't know what would work the best for the N/Tw/T setup?

SAFC, MAF-T, DSMLink. It doesn't matter. Something that you can mess the air flow readings with. I'd suggest a wideband for proper A/F ratio metering but it's totally up to you.

Everything pretty easy to install never messed with anything electrical. See I am a an engine builder not a tuner, although I would like to start. I have read a LOT about DSMLink, but what about the wideband does that just give you more accurate readings?

accurate readings ,it can also replace your stock narrowband sensor and still send a o-1v signal (narrowband) to your ECU.. look mfor a system with a controller funktion and a datalogging funktion.

i on the otherhand am goping to get a eCU reflash done at the racing tuner yes it will cost as much as a wideband setup(inkl all toys) and a safc2 combined,but all i need to do is get bigger injectors and put em in,drive to them..pick it up a few hours later.. just hope i can get an appointment soon..rally season is on and all the race cars are parked outside that shop all day

just use a stock maf for now,my maf is a nt one..no probs.. dont try too hard to emulate the gst setup yet, just bolt it together and see how she runs,then start to fiddle with stuff..

i got stock injectors and a fuelpressure regulator.. stock MAF,stock 2g intercooler piping and intercooler..wastgate a 7psi,stock BOV,stock NT ECU..thats about it.. oh i ran coolantlines off the heatercore supply lines and i ran an oilline off the oilpressure switch(t fitting) thats basically it


the more stuff you change(u have a NT ECU!) the more problems you will have due to troubleshooting..just take it slow,start her up and see from there..

the 1g intercooler,downpipe,bov etc should boltup aok!

we are waiting on the results

Yeah I knew that, but how did you retain the N/T ECU remember I have a 1G setup I think I am going to need the Turbo ECU for the different fuel map right?

You'll mostly want the n/t ECU for it's knock to timing retard feature. It's a fail-safe feature to keep the engine alive a lot longer.

So let me get this straight, I CAN retain my N.T ECU, do the conversion, and be safe(ER) due to the Knock to Timing Ret. Feature? Is there anything I need to convert or change to retain the N.A ECU or does everything work fine?

Just do yourself a favor and use the turbo ECU. It's under $100US for sure and you can sell your n/t ECU to a local board member or whoever for $50US. To drop it in and rewire everything, takes only a couple of hours to a beginner or someone who does it half-drunk off 7 or 8 beers like me.

From that point, get an airflow converter to mess with the fuel delivery. The maps will be much closer using the turbo ECU, rather then the n/t ECU.

By airflow converter, I am going to assume you mean a GM MAF with a MAF-T probably? I am going to go ahead and buy the DSMLink, because with my comoputer skills I think i will be able to tune my car EXACTLY how I want it to run. Besides no one around my area would be able to compete with tuning like that. Sleeper city.... Yeah that sounds like what I am going to do anyways. The turbo ECU in my car with the wiring, MAF and the Knock.

Im thinking on turboing my nt 91 talon but i have a Q about pistons and rings. If I just use the same pistons and buy stronger rings will i still be able to turbo my car.

dont worry bout that shit now,just turbo the bi***..add afpr ..and shes good to go

im running 6psi all day,stock 4g63nt internals..no prob..eurospec had even higher compression..no probs

if u change the rings ,u might as well change the pistons..

Add stronger rings? I'm not even sure if that's possible. Either way, it's not the rings that blow. It's the actual piston.

Just turbo it and make sure you have a respectable A/F ratio with no knock and you'll be making some good power.

safc lies to the computer about air readings, high compression low boost cuts down on boost lag , and i have 450cc injectors with no fuel tuning or correction in my 1.8t and i can bounce of the revlimiter at 6500 rpms. i dont run to rich at all. maybe it is because the size of my fuel pump (not sure the size) im buying a 1g n/t 5spd. and i plan on turboing it , i have allready

stock turbo manifold
evo 3 16g
450cc injectors(they would have to come off my 1.8)
all oil and water lines.
small fmic
stock 1g bov ill have it recirculating
im making my own down pipe and 3in exhaust to the back
and i have intake pipings and what not

and im sure im missing other things.

things i need

safc fuel managment
data logger? maybe not sure

just do what I did and bolt up a 13g/intercooler/etc., here's a link for the kit:

Just do what I do and check the date of the last post. (cough*threemonthsago*cough)

if a thread stops for a while you can't reply? my bad didn't know.

just adfding to my last post//number 319//

i stated i was running 6psi, well since i posted that ive been runni9ng 12 psi creeping to 14 all day long..

i used a SAFC for fuel
rx7 460cc injectors (high impedance since i didnt have a resistor pack)
and a zeitronix wideband for AFRs

i tuned for a 10.8 at wot.. i know i can tune for a 11.5 ( tried, car felt better and stronger)

well,its winter, im upping to a big t28 or a 16g.. and ill run low boost first(6-9 psi) and see what happens..(still have 2! nt spare blocks.. )

oh im also upgrading to a fmic and 550 cc injectors (rc makes high impedance ones)

engine> 4g63 nt with 9.7 CR
