Best turbo for my setup?

[Bwana]

Give me your opinions. I have to build a custom manifold anyway and it's time to choose a flange. I already have a stock t25 and a sr t25. Current setup looks like:

Stock internals and camsI have a set of stock injectors and some 660's (maybe kinda big?)stock SRT-4 Neon FMICSDS EM4-F standaloneand I'll be running a full 3" exhaust w/o a cat and minimal muffler.

I'm not looking for crazy power (it's a 1800 lbs MGB) but since I have the opportunity to set it up with pretty much any turbo I figured I'd get you guy's opinions.

Since you are using that big of an injector, why not take advantage of them with a decent turbo. I wouldn't toy with the T2-poot turbos. I would look more into something T3 based, but not too big or laggy. T3/T04B was a big hit with my old car yielding impressive #s and excellent street performance. I now use a T3/T04E which is also impressive on both the stret and strip. Trying to use a large ball bearing turbo on your set-up is not necessary unless you just want to. Hope that helps.

Yea, I've been thinking about a t3. What are the AR #'s on yours Dee? Like I said, I don't need/want anything real huge. This is a street car so I want something that'll spool nice down lower and will still allow me to flow some decent air. What do you think of the td04/td05 turbos???

[Rookieca18det]

I had a td05-14b on my car and it was pretty impressive, even with my leaky wastegate. Good response and made my car real fun to drive. The most boost it saw was 15psi so im not sure about the amount of boost it can take before it starts becoming inefficient though. Hope that helps a little good luck.

I have an HKS GT2540 and really like it except waiting til 4200 or so for the boost to come on strong.

For you, I'd recommend a T3/T04B stage 1 with .48 rear housing and .50 front cover. If you value my opinion and experience, go for this turbo and promise you'll be buying me a drink from afar ?

You have a deal there, provided I can find one at a decent price! What did you do for a wastgate?

And you might have to come a ways for that drink, 'cause I've never even been to FL!

You can use one of SS autochromes or stone mountain racing or XS power's wastegates because those indeed work (I can atest to this). I wouldn't pay no more than $450 for a T3/T04B. As for the drink, whatever drink you like, just send me the chump change and I'll drink to the fact tha you are happy with the recommendation.

So what manifold are you gonna use to mount that t3 turbo....

[Bwana]

I built a log manifold. I know it's not the best performance wise, but this is a custom installation and I don't have a ton of room to work with...

hey dee seeing we are on this topic, im stuck in the middle of a new turbo i was thining t3/04, but dont know about the lag, is it that bad or no?, and where can u get a decent manifold i dont want to mess around with ss auto, so i was thinking a gt28, but almost for the same price i can go t304 whats ur input?

Chosing the right turbo in the right configurations will make or break your expectations and/or your car/engine's performance. I recommend thge same turbo I recommend for TheColoradoQ simply because I have tried a multitude of turbos on the CA and many of them had lag, but the T3/T04B with a .63 or .48 rear housing will get your little 1809cc or 110cid engine up and out.

[Winona]

thanks dee, ive been going back and forth between the gt28 and the t3/t04 and u just convinced me

[capwred]

dee do you like the t3/04b over the 2871r

[boost_boy]

dee do you like the t3/04b over the 2871r

I chose the T3/T04B because I wanted a turbo that will be not only flexible, yet effective, that will be efficient, yet perform great for street/strip duties. But the coolest thing was its cost and the ability to toggle through wheel sizes and different housings. The gt2871r is a good turbo for what it is, but in the world of user or equipment failure, I can't afford to replace one everytime they fail. I hope this makes some kind of sense to you.

Dee

[capwred]

you make a great point dee.and understand what you are saying.

[Winona]

i have a friend who is has a t3 super 60 who is selling it? just wondering if anyone uses it and how bad is the lag on it?

GT2871R-15 with teh GT25 .64 A/R turbine nuff said...

[SeVa-S13]

Dee beat me to it a while back.T3/T04B with a .48 a/r turbine housing.It'll spool pleasantly quick and still provide plenty of room for power growth, and be like 1/3 of the price of the trendy GT turbos.http://www.westcoast-turbo.com/turboa.html

[CA19DET]

well the T04E owns the T04B no matter what boost you are running and in this case compressor housings and wheels dont effect spool so get the TO4E as it will allow you to run more boost in more of an efficient zone.

so if its a T3.T4 combo you getting get the:

T3/T04E50 Trim w/ 0.50A/R TO4E compressor (3"in 2" out)76 Trim w/ Stage1, 0.48A/R T31 turbine (4 bolt Vban)

if you can afford get teh BB and get anopther 500-800rpm spool and much better part throttle and intransiet boost reponse etc..

Hey coloradoQ, have a search on the net for a ca18det powered mgb, im sure i came across one a while ago. Might be helpful to you. They not a bad little car, i have crewed for a guy in nz running one with the old pushrod 1800 taken out to 2100 with all sorts of goodies and it went like a cut cat!

[Bwana]

If you come across a CA/MG conversion (besides mine) definately let me know!

[CA19DET]

my dad has an awsome MGB

british racing green, like new
