SWAPPING A T25 FOR A T3

[edsz31]

I going to swap my turbo, 1st time for me. Not sure to just swap it at the 4 bolt flange or remove the left manifold assy?. I don't have a/C compressure and It looks like most all the heat shields are gone, well except the exhust manifold head shields. I can get a wrench on all 4 flange nuts, except for one, looks like I need to remove the oil feed line. So whats the best way to swap? thanks Ed.

I personally think its easier to just pull the manifold/turbo assembly all as one.

I agree with FlawleZ so long as you're VERY careful about the head bolts. I snapped one on the first na2t conversion that I did and it sucked hardcore. I ended up having to remove the motor to drill/heilcoil it.

turbo swap

Thanks. for the advice>

Yeah, you need to remove the oil line to get to the front pass side bolt. I take them out by remobing those 4 bolts, there is no need to remove the manifold, just jack up the engine a little and you can pull it out of there. Even with my larger aftermarket compressor, I use the same method.

I find it much easier to just unhook the steering rack and rotate it out of the way when pulling the turbo. I wouldn't recommend trying to pull the manifold.

turbo swap

I swapped it today, did not remove the manifold. Popped the drivers motor mount, raised the motor a little, loosened the rack a bit and presto, T3-T4 hybr Installed. Thanks....

Thanks for telling me how you did it, i have to swap my turbo. Anyone with a NON F-ed up T3 of some kind want to sell it to a poor college kid? My exhaust side seal is leaking like a siv making it randomly smoke at long idle

Dude my car does the SAME thing. I need to get my T3/T4 rebuilt already.

yeah, it was embarrassing when it first did it a couple days ago, right in front of all the peeps at school

FYI: If you idle it at ~1500rpm that won't happen because the turbine will continue to spin fast enough to keep the oil from drilling out into the exhaust. Sure, you waste more gas... Can you tell I've had well more than one car with worn out turbocharger seals?

[MrwassmanNA2T]

Yeah, that is what i do, all stop lights. I think i made an uh-oh on the conversion...

The oil return hose off the parts car would not go on so I Made another one. But the turbos metal peice came sooooo close to the oil pan that i had to trim it. Well in my investigations the return hose is slightly kinked and i think that caused to much pressure and made the turbo seal blow. I kick my self. Sound sorta logical?? :shock:
