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.

Update: bought an OEM manifold, cleaned up, opened up a bit and ceramic coated good for up to 1600 degrees F... nice black finish.

nice job on the manifold.looks good

just curious why you wouldent want an internally gated turbo? i found with my ct26 the wastegate regulated the pressure pretty precisely.


just tring to give you another perspective


you could avoid having to purchase an extra piece of equipment.

you can always wedge the actuater arm closed so the internal wategate never opens (or wield the gate closed) then add an external later if the internal wont suite your needs

you may find with your desired psi/driving style a supper precise wastegate may not be necessary


in any case, good luck on the build and please keep us posted on the progress

peace
