2g T25 to TD05H turbo

[sp98gst]

I'm currently in the process of swapping my stock 2G turbo with a TD05H 16g turbo and I still have the stock SMIC set-up. What would I need to make this work?

 

[TSITurbo95]

A new oil feed line, j pipe that faces towards side mount. You can reuse your stock water lines, you'll just have to bend them out a little.

If you bend the stock water lines don't do it with them bolted down. It will cause them to bend rather close to the bolt ends, and possibly kink, and the eventually fracture. I was having some very odd overheating issues for 3 months until I figured out the previous owner just bent the t-25 stock water lines to fit the 16g and one had cracked.

^ Heh, I do mine bolted to the cartridge, as I find it easier to bend and I get an idea where to bend them too. But if you do it my way, just be cautious, and make little bends, and do not kink the line!!!

Same as above , but get another oil return or hack the t25 oil return line, new manifold to turbo bolts, related gaskets, a aftermarket boost gauge, and a wide band guage just a few things that I would recommend for the safety of your motor.

You can slide the stock piping up on the J-Pipe, you may need to tweak it a bit according to the angle of the J-Pipe. Good luck, it's a worthwhile swap

Thanks for the help! Just got to get the parts, now. Hopefully everything goes good.

Would it be wise to put in a walboro 255 fuel pump, too?

 

[JusMX141]

Sure, if you're ready to buy an adjustable pressure regulator as well. Otherwise the 255 pump will likely overrun the stock regulator, screw up your tune, flood your crankcase with unburnt fuel, wash the bearings, and eventually blow the engine.

 

[sp98gst]

Nah, I'm good. I'll just stick to what I have.

 

[JusMX141]

Stock pump's not going to get you far with anything bigger than a 14B. I'd recommend using a 190lph Walbro which does not exceed the capabilities of the stock regulator. This would be fine for boost levels up to 20psi or so with an Evo III 16G.

I have a big 16g with a SMIC and it works fine. Granted im not pushing over 15lbs cause of the stock fuel pump and injectors but when you get the pump JusMX141 is right you need a fuel regulator but its worth it. If you get 255 Fuel pump, Fuel regulator, 650cc injectors, a Fmic, and an aftermarket BOV, you can easily push 20lbs just dont forget your gauges to monitor your baby.

What SMIC do you have? If he got all that and tried pushing it to 20lbs he would have to have a way to tune right? Or could you just use the afpr to run more fuel with the bigger injectors and fuel pump?

Ran a small 16g at 17psi on a stock SMIC for a year before I upgraded. Not very efficient but it was fine.

 

[ricktb]

get a hallman pro boost controller, and tap a 1/8 hose fitting into the td05h housing or j-pipe close to the turbo outlet. Run this line to the boost controller and then to the wastegate actuator. Keep below 16 psi until you get proper fuel and intake setup.

I have a stock SMIC and yes its preffered that you have a tune cause its better for the car anyway but yes with the regulator it will push more fuel but only with an aftermarket Fuel pump and injectors to co-inside with the air ratio and you can hit 20lbs its just not suggested cause with a Fmic its way more efficiant and way cooler and better air flow

Skip the Walbro 190 and get a used Evo IX fuel pump. 200lph, built to last OEM lifespan. No Walbro whine.

Direct bolt in.

 

[sp98gst]

Still working on getting the fuel pump, but as of right now, my car won't accelerate like it should. It gets up to 40-43mph(slowly) but after that, it doesn't want to accelerate. Any ideas?

 

[99ECLIPSEGSXDSM]

Have you done a boost leak test? Did this just start or has been going on sence you put your turbo on?

I'd stick w/ the smic just because it is inefficient. Too many times guys run out and buy a turbo 1st. If the turbo went bad, i understand. But all the other mods needed aren't there yet, it's a recipe for disaster. the inefficient smic may save his freakin motor...

 

[sp98gst]

The problem just started, I got the turbo put it and it drove home just fine, about a week later it started acting up and now it's permanent.

 

[99ECLIPSEGSXDSM]

When you installed the turbo did you prime it so the turbo had oil before you actually turned the car over? If not you might have killed ther turbo. Check the intercooler poping and see if theres oil. You didn't say if you did a boost leak test that I saw. When I put my 16g on I left a coupler on my piping loose and it felt like I wasn't going anywhere cause I wasn't getting boost to build up!

 

[Ralliart567]

How does the car run right now

 

[sp98gst]

As of right now the car doesn't start. The car cranks but for some reason it just doesn't spark. I think I may need a new crank sensor.

The intercooler has oil in it as well as the piping. While driving, it seemed like the turbo pressure wasn't being released enough after coming to a stop then accelerating again.
