5S-FE Turbo project, Would like comments/critique Options

[Syaoran]

Hello, this would be my first elaborate post on here and I thought I'd get some feedback from you, the more experienced people.

I would like to know what your opinion on my idea for a boost build would be.

First off, I'm not going to use a CT-26. I would really like to, but the reason is that the ones I've found, that are NOT supra CT-26, are either in need of a rebuild or way too expensive for a small, old turbocharger, that isn't even a ball bearing to justify the price. That is my take on the CT-26. The CT-20b is way too rare, and expensive to rebuild in case I were to find one.


That leaves me with brand new eBay turbochargers. I have first-hand experience eBay turbochargers and I can say that some sellers do sell decent stuff. Ilovetacotaco sells some good turbo chargers.

My main question in relation to this topic is whether I should get a .50/.63 or .60/.63 turbo, considering I'll be using MegaSquirt-II or MS-III, undecided yet (have a friend that's been using them for more than 10 years now, he knows these EMS)

I plan on getting a cast T3 manifold with external wastegate. I'm looking to obtain above 250whp. I believe I should run relatively large injectors, right? Something like 460cc or more? Should I look into forged pistons and rods or should I just keep stock internals until I decide to go more boost?

My budget is about $2700, and this is what I've broken it down to.


1. Cast iron manifold $200 (add $50 for inside-out ceramic coating from a friend who does that)
2. Turbocharger ($150-$300)
3. Wastegate + BOV ($100)
4. Lines, flanges and welding work ($300)
5. TMIC or FMIC (~$300)
6. Pipes/t-clamps/silicone joints ($100)
7. MS-II ($400) / MS-III ($600)
8. 460cc RX-7 Injectors ($100)
9. Fuel Pump + Regulator ($200 if needed in the first place)
10. Gauges (Wideband, Boost, Oil Press. / $350-400)

Total: $2600

I know it'll be more expensive. I'm just wondering if I'd be able to get some things cheaper. I KNOW cheap/fast/reliable, but there's a fine line between what's considered "cheap" and just shelling out money for overpriced stuff.

I know I can rely on some eBay stuff. Most of the time cheap knockoffs are just as good as the originals, as most companies sell you something cheap for a lot of money because their brand name is on it.


Should I do TMIC or go for FMIC? I've already got the All-Trac hood, so I can fit a nice, small FMIC as a TMIC. I'd rather have a more simple setup, boosting 10-12psi. The less lines/pipes/etc, the better.

Your on the right track, don't bother with the ct-26.
Above 270whp, the tune is gonna be critical. One good hiccup, and kiss the stock ringlands goodbye.
For 300+whp, I would definetly do forged pistons, the rods are not weak, but the rod bolts are known to strech in Tue older 5th gen motors.
If I were building another 5sfte today, I would do it one of 2 ways.
For sub 300whp, I would grab a 20b, run 16-17psi with water injection with a stock unopened motor, with the emanage ultimate, or ms, and tune it myself.
For above that, I would drop in a set of stock sized forgies get cams and have an intake manifold made,, spend all my money on an ems and tuning, and run a gt3071 or somthing similar.
