Default Ford SVO T3 T04E???

So i found one of these guys for a good deal.... fresh and rebuilt/hi-temp coated. Anyone run one of these? It is in my price range of $500. Should i grab it? I've heard the SVO turbos are quite nice.... and this one looks brand new (and not 'garage cleaned')

the specs were emailed to me saying "Garrett T3 turbo with 46 TRIM TO4E 51MM INDUCER 75MM EXDUCER and .60 A/R compressor. The TO4E compressor is much more efficent and you will have lower air temps to make more power Exhaust housing is .63 A/R and a high temperature coating. Turbo is internal wastegated."



and he included a map

It looks like a standard t3... did they hog out the compressor housing for the t4 wheel? Otherwise... its being misrepresented.

I run a t3 60/63 (the SVO/xr4ti/thundercoupe) turbo on my honda... its a nice turbo... but not worth that much.

He's including a map for a straight up t4... which that pictured is not. Even if it has the wheel fit inside the t3 housings... that map will not represent it anymore.

It also isn't internally wastegated... it has the hole... but you'll still need the bolt on housing with the flapper built into it.

Split, that is the correct flow map.

with a 75mm exducer, it's for sure a t04e.

51^2 / 75^2 x 100 = 46.24 trim

that's all a t3/t4 is, a t3 turbo with a t4 compressor wheel on it.

a standard t3 will always have a 60mm exducer.


the only thing you'd have to worry about it slower spool (but i think it would be fine on your engine) and right now it has no wastegate.


easiest way to put it to rest would be a quick shot of the compressor wheel itself, i could tell you just by looking if it's a t3 or t4 wheel.

That housing pictured looks like the standard 60ar housing. For some reason I thought the compressor maps where linked to both the wheel and the AR. Considering that they work together somewhat. I realize the wheel design and size controls most of it... but I just wanna link them

On a side note... i have a Precision sc50 i'll be trying to rebuild shortly... it would be a nice candidate

I had a T04B S-3 wheel in a standard .42 A/R AirResearch compressor housing.

just a little bit of machine work is all you need.

oh yeah, seller IS including actuator/arm assembly.

But i figured since it is practically new (rebuilt and unused), it'd be worth the extra $$ as opposed to a straight up used turbo.

how big of a difference does it make that the wg gases go into the exhaust stream? Im not going for some crazy meticulous setup or anything. just simple and effective for decent cost.

it's fine. it may not be the most ideal perfect thing in the entire world, but it's still very common and nothing to really worry about.

so think i should pull the trigger on this turbo??

the way i see it is the other (new) turbos i have looked at are all $600+.
If i get a used turbo, im going to send it off for rebuilding anyway... i dont trust used turbos from people i dont know.... im sure that'll be $200+ to rebuild a turbo.

I am not sure about the price, Brain would be the best on that info. I am not sure how much a good used t3 goes for.

T3 turbo rebuild kits are more in the range of $50, my local turbo shop does professional balancing for around $30-35. That shop charges more like $250-350 to rebuild turbos though, thus the reason why I would rebuild my own.

I paid something like $495 for my T3, which ended up being a t3/t4 (stupid shop), then i swapped over a 50 trim coldside I had, and then spent another $100 and found a super 60 wheel and housing.

then i sold my old parts for about $150.

one thing to ask is if it was built with a 360° thrust bearing. But it looks to be in pretty decent condition.

rebuilding is very easy, it will take someone an hour is he's never done it before (with the right tools). See my writeup in the archives. The wheels are balanced separately so it's not vital to get it balanced as long as you mark the position of the wheels in relation to each other. I've never rebalanced a turbo (4) and never had a problem.

i appreciate the information

But it would be my luck to FUBAR something in the process.
This turbo has had the bearings/seals replaced and everything was rebalanced.

Looks like the ATP piece? (if so, contact wideopentuning for his discount there) I have a similar piece, but its for gt28 usage.

unless he's rebuilding mine, than it takes 3 months... and another 3 months to meet eachother to get it back ps when you wanna meet?
