hey guys im building my 2,4L s13 and am faced with the choice of what turbo to choose, basically i have a few hook ups at the wreckers so this rules out a nice t4/t3 hybrid. Id like to boost about 8-9 psi and net about 220whp. what are some choices with turbos i dont want it to spool forever as my stock redline is a mere 6500-7000 rpm, Id like to spool at about 2900-3500 rpm, id also like to keep it internally gated

some choices avail at a junkyard:

Volvo T3
Thunderbird T3
DSM 14b
DSM T25
Saab t3
Audi KKK K26
MAzda IHI RHB5
Holset cummins turbos
Toyota ct26
T4
85 300zx t3 AR.63 and exhaust .60 im kinda leaning towards this one it came from a 3 litre

LOL

I would say the T3 off of the 300zx Its a damn good turbo and it won't spool out they work very very well on a 3.0 i would suspect that it would work well with a 2.4. Early spool time

 

will she pull till 7k

 

A T-bird T3 from a manual transmission car would be easier to find. I didn't do any calcs, but it should put you in the right ballpark for hp.

 

can u dbl check

 

ya the tbird super coupe T3 is pretty big if it's from a 5speed. .63 turbine and .60 comp I think. Should flow more than the saab/volvo t3s and the t25- 14b mitsu. I don't have any experiance with the 300z t3 but it sounds kinda like the thunderbird one.

I think it would be pretty easy to make 220 with either one but you might need a little more boost, altough I have seen some dynos of KA motors at very low boost (5-6) and making pretty big power and LOTS of torque.

 

holset owns... more flow than sc61, spools 10psi at 4800 on GSR...

the main turbos ive seen used out of the junkyard are the following

.42/.48 T3--Saab 900 before 93, volvo, and a bunch of other cars
.48/.60 T3--Auto SVO...great turbo for any daily driver
.60/.63 T3---Manual SVO---good turbo for b16(laggy), b18b1...im not sure about the c series...

14b's are used often, personally i find them difficult to use b/c most manifolds for hondas use T3 flanges

T25 is generally even small on a D series engine and someone posted recently they were almost in boost driving around in Mcdonalds...

Personally, i like the .48/.60 and the .60/.63

 

anyone know if the 300zz auto/manuals changed trim sizes

um that turbo won't be laggy on a b-series, ive been in friends cars with that turbo on a d-series and it hardly had lag... IMO its alittle small for a bseries

 

I have the SAAb 9000S turbo on my CRX D series. It was good while my engine lasted.... At around 6 psi I was making close to 170-180 hp. It pulled hard, but becuase of the way I had my intercooler piping set up, it didn't hit full boost until about 4,500. It started pulling around 3800.

 

well i bought the 300zx t3 today, looks pretty good and i got it for 100 canadian

 

i has water lines is it mandatory to hook them up?

 

I would.

 

reasoning please

 

um...why wouldnt you hook up the lines?

Also it prolongs the life of the turbo by a lot

 

thanks, just needed a reason
