t3 or t3/t4

thats why i recommended the t28 (if he MUST go with a t series turbo), it would be a much better street turbo

you are correct temp, but the problem is this guy wants numbers. and its not really worth it to build a motor to run a t28, by the time your running enough boost to need forged internals, your pushing the envelope of the compressors efficency index. on a turbo that small, your blowing little more than hot air when a built bottom end becomes necessary. which is why i suggested the gt series- larger housing and compressor, but spooling similar to a t28 (if he sizes it right) . but damn those things cost a grip compared to the t's.

true, or he could go with a K^3 turbo 8)

I've looked in to the k3s, but almost all of them I've found have f**ked up flanges that wont work with normal turbo manifolds. I don't want to have to do any work to the turbo to make it work.

so rather then have a nice streetable turbo you want to go with what everyone else has because you want peak power? i would rather have a huge ass mid range and some top end then all top end

ok

 

[TurboBoostinSI]

ok so which one did you buy.

 

[SeanMc300]

if you want kiler low-mid...get a ihi rhb5 turbo... has a t3 flange and all.

Got a good deal on a t3/t4. If I don't like I can sell it and I'm almost guaranteed to make money anyway.

I have some other questions now tho. What would be best to buy for a boost controller? Will a manual one work, I should I spend the money and get a greddy or an apexi?

 

[SeanMc300]

manual ones will work fine. you can make your own. if you interested i can link yo uup

 

[Sound Streamin']

How much boost can teh manual handle, same as anythign?

 

[iamgod]

get an electronic unit for more PRECISE adjustments

 

[SeanMc300]

manuals are fine, just turn the dial, run it and make sure its set at the proper boost level you want. friend of mine made the same manual boost controller and its does 15psi on a toyota celica all trac

good for him, boost spikes will be more common with a manual boost controller

 

[SeanMc300]

well id rather spend 10 dollars on something that works just as well as a 300 dollar piece. thats just me tho.... no problems with it so far, or the one he had on his old civic....

i would spend $300 on a quality piece of equpiment rather then something you buy at a store that sells fish tanks

Im just gonna go manual for now. Once I start running some serious boost Im gonna get a better one.
