Lets talk(civilized) about turbos.

[Aries_Turbo]

i have the equivalent of the MP Plus turbo on a 2.5L. pretty much stock minus the intercooler, forged pistons, TU3" sv and 3" exhaust. full boost by ~3k in the lower gears and in the upper gears, less than that.

13.1 @ 104 with 18psi on a cool night. pump gas no alky.

If I missed it, I'll apologize now. I didn't see a straight answer on my housing question. Would it be better to change the exhaust or inlet side or both? I'm talking about just bolting on the larger housings.

more diagrams would help on a/r and that stuff. At least someone posted some pics!

True story when launching, but driving it around you might...

Flooring the Z from a slow roll in any gear at 1000rpm wont net good boost till after 4000 (doing this in 1, 2 or 3 will result in violent wheelspin when the boost comes on) launching at 5000 it instantly makes a few pounds of boost then hits 15 or whatever the setting is shortly after.

I guess you are right. Even with the 9 psi launch, I still don't go above 20 psi until around 4500 rpms and I don't hit max boost till around 5000.

yeah thats pretty bad actually. i wonder whats up with that S70 to make it laggy. i wonder how it compares to a 46 trim T04e cold side.

Do you think my spool time will decrease with a ported head, intake and header? If not I guess it is time for

making the engine able to move more air without the turbo will absolutely help the turbo spool

Depends what your power goals and use are. Not sure you can make any gains from switching the compressor housing without changing the wheel to match.

46 trim To4e and a stage 1 wheel with a .63 housing is a good combo, to which we've already mentioned,

yeppers...

stock < MP Plus (.63 turbing housing only) < Super 60 (.63 like the Plus and also the S60 comp wheel)

One correction here: stock< MP Plus (.63 turbine housing and a 60 trim wheel (stock housing inlet machined for the bigger wheel) < S60 same as MP Plus but with a S60 trim wheel (housing?).

Well, My Garrett(T03) was just rebuilt this past summer, that is why I asked. The other reason I asked is that it is said you can put different housings on the same wheels(I realize it differs from turbo to turbo). My thought is that with the bigger housing, it won't be able to make any pressure or very much.

Didnt think the Plus had a larger than stock comp wheel?

sure will.

All of the above

I thought that too, then Simon said it wouldn't make any sense to do that. Not picking on anyone, just asking.

The + had a 60 trim T3 compressor like the Ford T3's. S60 is slightly different yet. Most weren't aware of the compressor being different as the Dodge garage only mentioned the .63 A/R housing.

[Aries_Turbo]

huh, didnt know that. i guess i dont have a plus turbo.

Yeah ... remember that post tryingbe started when he picked one of them up? It's on the forum here with measurements too I believe.
I bought a used one from Brad in chicago a while back to replace a tired stock T2 on the '89 tona. Got it in the mail and figured to swap my T2 housing cover over because the MP+ in question had the earlier cover. Well guess what ... he wouldn't fit. Busted out the calipers and sure enough ..inducer was too big.

I know DDG says otherwise ... along with a few other members but I know that info isn't right. There's mine, tryingbe's, and Rob (Shadow on here) mentioned that he had a buddy that used to do rebuilds for garrett and he did verify the difference in comp wheels as spec'ed by garrett.

From what I understand, ma mopar offered a MP turbo and the MP+ turbo back in the day. I'm guessing that the MP turbo had the larger .63 housing only. The "+" added the 60 trim wheel. Sound right?

[BadAssPerformance]

Interesting... I'll have to dig up the MP catalogs and see what they said

I don't know what compressor housing will fit the stock wheel and if you could find one, what difference it would make, which I would bet, nothing. The .63 exhaust housing is worth it.

Lets see if I have this right. Putting the .63 exhaust housing(just the housing) on a T3 stage 1(stock) exhaust wheel should make more power?
