Looking at the T3/T4, CT26, and the TD-06. Which one would be the best for a 5sfe? I do plan on having Forged internals.

CT-26 is stock....below the the league of the T3/t4 and TD-06

personally i like the T3/T4 Garrett turbos over Mitsu TD06...that and specify which T3/t4 because there are A LOT

Would the CT-20b be an option?

Iunno, havent heard of that one lol.

I'm not too knowledgeable about the different t3/t4 makes. I just know that they are an option. Between the t3/t4 and the TD-06, which is more reliable and has more WHP?

CT-20B is on the 3rd gen 3S-GTE and good for up to 300-320bhp. But if you buy it new your better of with a GT28RS from Garret.

You also didn't state what power goals you want to achieve so its a bit unclear what your best choice would be.

Hoping to achieve somewhere between 300-400 whp

i hope you have 10k+ for that kind of goal with a 5s.
read the stickys.

GT28RS disco potato FTW!

anyone know what type of exhaust manifold is needed in order to use a t3/t4 turbo? I heard that the 3sgte manifold won't work.

you are waaay over your head at this point....i wouldn't even bother asking what turbo ect...read the stickies...go over the MR2oc.com and read the info they have there on the 5sfte...
there are at least 5 different t3/t4 turbos each behave differently...
plus supporting modifications, ie fuel, tuning, pistons, head work....there is much to this.

but easiest answer for 300whp on a 5sfe

3sgte exhaust manifold
adaptor (ATS/Koracing?) to fit a t3/t4 turbo
T3/t4 50 trim
+ 6 grand worth of other parts if not lil more?

IMO, you should start with a base 5sfte (like Shin or Pressure2)
using the 3sgte OEM pieces.....and learn what that level is like then move on up...u no ready for your posted goals

agreed with that perspective. i'm just gonna keep asking questions about random things which may seem redundant to most.

has anyone ever done a 300+ whp 5sfte? most powerful one I know of is presure2's at 235 whp... but I don't go on mr2oc that often.

Im pretty sure Ive seen it on mr2oc.com. I could be wrong but I believe Ive seen it.

yup. built bottom end, big injectors, some cams, and somthing other than the ct-26, REAL EMS, and maybe a splash of 110 octane, 300whp would be no problem for a 5sfte. throw in a intake manifold and a TB to match, and you'd have a NASTY 5sfTe on your hands.
im dying to see someone throw a gt-28rs on a low mile 98+ 5s block.
i think it would be a BEAST at low boost, and absolutly SCREAM with cams +EMS.

even better would be a built bottom end, 1mm OS valves, port, bowl and throat correction, custom intake manifold, Q45 or mustang TB, HUGE fmic, 3" piping, and somthing like a gt3071 @ 20+psi.

if i had lots of $$, (or access to more 98+ motors, cheap!) i would LOVE to find the limit of the bottom end.
they say one of the major weak points is the rod bolts, but all that stuff seems to be more of a problem on the earlier 5s' or the ones who've had oiling issues.

Oh, I know it's possible. I'm wondering if anybody has done it before? yeah, later on down the road when I have a job where I actually make more than $8/hour I want to do a 5s with all forged internals, cams, CT20B or GT28RS turbo, and some good tuning with an emanage ultimate (or standalone). and hope for 300 whp.

Oh, and also swap the tranny with an LSD e-153, and big sticky tires

well anyone who is serious about a buit 5s i do have one. It has .20 overbore, cp pistons(8.5:1) crower rods, arp head and main studs, balanced and polished crank, new oil and water pump, cometic head gasket, lightened factory flywheel, rx-7 injectors, adapters for turbo feed, clevite bearings, and rebuilt head WITH a REBUILT ct26 rebuilt by turbo performance in california with no miles, engine has no miles..anyone interested make an offer

I had a older 5sfte and I would check the condition of the engine and build it first. I spun the rod bearing in my car in less than 100 miles. All the power to you but I just wanna share my .02 listen to presure2 he really knows his stuff!

>
yup, but yours was the earlier version. with no knock control, shannon.
that makes a HUGE diffrence.
not to mention the ebay turbo kit..lol

See that goes to show you shouldn't cut corners!
