Hypothetical Turbo Kit

[Deep]

Fuel Pressure Regulator $100
Alltrac MAP Sensor - 2 BAR $80
360cc Fuel Injectors (7MGE Supra) $150
Braided Oil Supply Hose $20
Braided Return Hose $20
Braided Coolant Hose $20
NGK-BKR7EVX-11 (0.34&quot $7
3SGTE Exhaust Manifold (Alltrac) $60
CT26 (MKIII Supra) $300

optional:
Intercooler (Mazda 626) $50
I/C Piping (Supra TT) $50
Misc. Fittings Hardware $40
Bosch BOV (Saab) $60
Boost Controller $30
94-99 5SFE Pistons $200

This would be my setup, all in USD with some used parts mixed in with new. What do you guys think? I figure I'd be good for 7psi. With the 94+ pistons and an I/C, maybe 9-10 psi.

You would so's need an intercooler...
unless you wanna collapse a piston...

[SCEPTER300RR]

the 5sfe pistons are they forged??? for 200 bucks?? or just stock ones...

thnx..

humpty

The 94+ 5SFE pistons are forged. Anyone know what a 5SFE shortblock goes for?

Sounds pretty similar, but the kit I outlined would be easier. All the parts required already exist or are easily modded to fit. I know you know your sh*t, so what do you think?

I feel compelled to share my research on this issue that haunts all of us with 5SFE engines!!

Check out these local tuners:
http://www.karspeed.com
http://www.extremeboost.com

I even got a schematic drawn up and different contingency plans. All I need is just some damn cash!! :sad:

Sport Compact Car has a lot of educational articles about turbo charging. They have helped me out a lot in doing research. The last issue has a listing of all the turbos out there, even the junkyard treasures.

sniff, sniff... What's that I smell? Jeff about to get a little bit of help from some turbines :wink:

BTW- I saw a mint condition older Black Supra (early 80s model, MKII?) around the Brimley/Eglinton area with a KarSpeed.com decal on the windshield today. Anybody know who this guy is? Did I mention it was in mint condition!!

can anyone confirm if 5sfe 94+ is forged pistons ?? i thought they were all normal pistons... except JE pistons with low comp...

My buddy Andrew (SE V6) has very extensive knowledge of turbos. I hope he hits this up.

If we got forged pistons, I may be more inclined to try double-digit boost. My goal right now is 8psi consistently, which should give 200 whp.

Here's a few pics to help us visualize everything. First, Sam's custom 4A-FTE setup:



A pic of the 5S-FE engine bay (on my Camry, but should be similar as the 5th and 6th gen Celis):



Other thoughts and questions:

- Manifold can be off an MR2T as well, since its got the same engine as the All-trac; but I'm wondering how it affects the orientation of the turbo. Since the throttle body is on the driver side, it makes sense to have Ithe exit to the intercooler on the passenger side, go through the intercooler, and come back up the driver side. In this setup, the air filter on the turbo will be on the driver side. You will see that Sam oriented his turbo the other way, which makes for more difficult bends on the exit to the intercooler.

- Relocating the battery would be a good starting point for a turbo project. I say we make that a TN DIY day. I already got rid of the cruise acuator (big box beside battery) to open up more space. However, this requires a different throttle cable.

- Depending on what your power goals and car usage is, determine the characteristics of the turbo you want. For me, I'm looking for a fast-spooling turbo (3500+ rpm) with street-usable power.

- Given most of us are talking about the 5SFE (2.2 I4) engine running low boost, what is the optimal diameter for the intercooler/intake piping, downpipe, and exhaust?

- Fuel management: I know we'll need a fuel pressure rise. Do we need a higher capacity fuel pump as well? Do we have fuel return lines on our engines?

- Any thoughts on managing spark timing? I have heard that retarding the spart timing would speed up spooling.

You can grab an ST165 manifold off car-parts.com for that much. BTW, those are USD.

[SpectraBlueCam]

http://www.karspeeed.com got them too. But I'm more inclined to get a tubular manifold for the badass factor. Maybe we can set up a group buy????!!

Any 3SGTE manifold will fit, it just that the Celi has an identical engine layout, so there wouldn't be any fitment problems.

Battery would fit nicely in the right rear of the trunk.

I would probably stick to a CT26, Supra opposed to MR2 or Alltrac. Just because my goals wouldn't be more than 10 psi.

We do have return lines in your fuel systems, a Supra fuel pump would work nicely and MKII N/A Supra injectors flow enough to tame 7-8 psi. A MAP sensor from a 3SGTE would be able to meter enough fuel for low boost.

Retarded timing should be ok though I haven't devoted much time to researching it.
