20g Q

[green hornet]

i just got a 20g from my buddy that only has 300 miles on it. i woundering what kind of mods would i need to run this turbo safely, pritty much right now i have a stock 1990-92 4g63 that i am doing a 2g swap with, nothing done to the motor it's self, i have a 2g mani on it but thats about it "oh ya motor is not in car yet"

intake, exhaust, tuning device, and 650cc fuel injectors should do it as the bare minimum. A front mount intercooler and some cams would help the situation.

You don't need anything special to run that turbo. Keep the boost under 15psi and it will fun just fine with no mods. Note that the compressor outlet is different though.

I just installed one on my buddies car.
His mods were, Tial Wg, intake, exhaust, stock fuel and stock controller, fuel pump, centerforce clutch, IC Piping, mbc and thats about it.
It runs pretty nicely on 15 PSI. We will be adding injectors and an SAFC this weekend. Would have done it last night but it got late. Hes also trading a guy another SAFC for Cams.
I would actually suggest bigger injectors then that if you plan on running more boost, better to be safe then sorry IMO.

What do you mean by a 2G? You don't want to put a 2G motor into a 90-92.

You will need a front mount intercooler, unless you only plan on running 12 psi or less. You will need full turbo back exhaust and an air intake. A tuning system like an Apexi SAFC or DSMLink. Bigger injectors 550cc or bigger, depending on the tuning system you use, the boost you want to run and if it will ever see race gas.

You might need to do some work to the O2 housing setup or get an external wastegate, if boost creep is a problem.

Some 20gs come with an elbow on the compressor outlet like my friends. His has the Turbonetics elbow on it. :)

yeah you may want to explain that a little more. but what i gathered is that you were putting a 1g block into a 2g body.

At first I thought what Shane did, but after rereading it, he is do a 6 bolt swap in a 2g. Putting the turbo on and getting the car to run and getting the potential out of that turbo will come up with 2 very different answers. Are you looking at just getting the car to run reliably with the 20g on it or are you looking to use the turbo to near its potential.?

[green hornet]

no i just want the darn thing to run right first, but i was thinkin of leting the 20g sit on my shelf and put the stock one back on till i get the motor in and running good. and ya its a 6 bolt swap that im doing. DSMLINK will come in june i hope, 650cc's in aug, i already need a fule pump so when it gets warm i am going to get a walbro 255, and i was planing on running a front mount, just have to get the car to run before i go out and buy that.

For stocker, are you talking the T25 or 14b?
