MAXTOUT

Will a Garrett T28 work for the maxima application?

Thanks

Work yes. Not really matched well for a large 3.0 liter engine. A 300zx uses 2 t28s.

So, if I can get a good deal on it, would it be worth it to use in a custom set up?

no...you're better off with a leaf blower

That is pretty small, that would work with a small displacement 4 cylinder engine. T3/t4 or anything bigger should be good with our engine.

What about a T66?

if the motor is built to "spin" it than yes

i know a guy with a T66 on a supra. he runs 10.60's

more than likely a stock VQ cant "spin" a T66 effeciently. in other words its to big

Why can't a maxima spin a t66, we have the same displacement as a Supra, I don't see why not. A big turbo like that will spin at 4500 or 5000 rpm and they is really close to redline. You will not get much use out of it unless you get on the highway. There are always way to help the turbo spool, so all comes down to what you want.

But as long as maximas use the reverse y-pipe setup instead of dedicated exhaust manifolds, the spooling characteristics will not be similar to those of engines of equal displacement like the Supra, 3000GT et cetera...

I really don't see how that would make a significant difference. Even with "dedicated" manifolds, the turbo still has to sit xxx distance from the heads. The spooling characteristics of a Supra is much different than for a Mitsu TT. The 3000gt/300zTT are similar. While the Supra is pretty much all alone because of it's straight 6 configuration

Displacement is probably the biggest determining factor for turbo size.

Slammed comment about a T66 might just be a joke. Hal might be running some big monster though.

Question is why run a T66? It won't spool fast enough and flows much more than the stock or near stock engine could handle. Even if the engine could handle it, the tranny wouldn't. If the tranny could, it's a terrible set up for FWD. Take your pick

Just go with 2 T88 turbos!!! Haha

i have the 84-86 300zx "T3" turbo. i think it has a .46 a/r which is tiny for our engines. even with my sohc heads it spools waaaayyy too fast for my liking. a T28 would be even worse, especially on a VQ since it will be able to move air better than my engine.

T28 is too small. It would work just fine, but you'd have a really jacked up power curve.

Yea, it's literally the size of a really big fist

Is a t60 samller than a t66 and if so will a t60 work on our engine?

stephenlc

iTrader: (1)

T60 is pretty big, I think it would be fun on the highway. The only reason we get smaller turbos like t3/t4 is to have boost almost instantly so you still keep the maxima low end torque. Big turbo would help with gas milage but when that thing spools, goodbye.

MAXTOUT

I assume that the T03/T04 that is being used on the max more often uses the .60 and .63 A/R.

I have seen T03/T04 turbos with different A/R numbers for hot and cool side of the turbo.

Yeah, it will work if you like turbo lag. A little too big for our application unless you have motor work. In which case, you would be better able to utilize the flow of a turbo this size.

And it is smaller than a T66. Bigger the number, bigger the turbo.

That thing is way too small. It's almost too small to use on a Honda. My girlfriend's Integra has a custom turbo setup we built using a Turbonetics T3 which is bigger than a T28 and it sees full boost by 2500 rpm and this is a 1.8L motor.

I know some Honda guys on budgets using T25's and T28's, and the turbo is too small for them with 1.6 and 1.8L motors. Spools very fast, but there is no top end at all since the since the turbo is maxed out. I couldn't imagine what the power curve would look like on a Maxima. Probably hit full boost as soon as you got on the throttle, but after that, nothing.

subs1000w

i think the .60/.63 is pretty common but ive talked to some people and they sugest going alittle bigger on the turbine side maybe .7 or .8 somthing just to keep topend

Just becuase the Supra is a 3.0 and so is the Maxima doesnt mean they will have the same spool characteristics. You are comparing a straight 6 vs V configurated engine. The length if piping, diameter, and tune will also vary the spool time and power difference.

Also, if you want quicker spool up, then run a smaller AR on the hot side. The bigger the hot side, the laggier it is but it makes bigger power since it can flow more out.

Also, a T3/T4 or even T3/T04E aren't that small of turbos. They are capable of laying donw 450+whp (depending on trims of course). Now, The T04R is just a monster of a turbo.

A T28 is a very small turbo. We tend to call those "T" too small. A T28 I think is even comparable to TD0413G.

What you guys need are compressor maps rather then guessing. Everyone says this and that, all I have to say is hands on experience.
