3SFTE project Options

[digs]

Hi guys, don't post on here really as post on a UK celica forum.... but thought I would share what I have done to my SSI.

Following the various 5sfte posts and guidance, I have now turbo'd my 3sfe engine, some pics of the engine bay (its had a little more done since this one - including changing boost gauge t-off point to the map sensor line) and other bits at end of post.

Have installed;

3sge injectors
ct26 turbo
emanage blue (getting tuned in a couple of weeks)
ST185 manifold
ST185 map sensor
2.25" intercooler pipes and intercooler
Apexi BOV
ST185 pan
boost and oil gauges
2.5" custom ss exhaust

Been a fun and frustrating build, the turbo would not clear the coolant hard lines on the rev 3 3sfe, so I had to source a spacer for between the manifold and turbo. Changing the oil pan is fun too! Didn't need to relocate oil filter, so that was a bit easier. Coolant lines off the throttle body so again pretty easy.

Intercooler piping was interesting, right side through air pox route, left side was a bit of a squueze! But did not need ot remove a/c or anything else.

Not driven it on boost yet, but has been driven for several hours off boost, and doesn't miss a beat. Injector size has gone from 215cc (rev 3 3sfe stock I believe) to 295 (3sge stock), running on stock fuel pump, so some scope to improve there.

First map though is just a safe one to ensure no det, etc. Plans next will be;

wideband sensor and gauge (hooked into emanate)
prob bigger injectors and fuel pump
sort out second output for boost gauge from throttle bottle to leave map sensor feed unmolested
Wilwood 4 pot brakes

looking forward to running boost!

As you see, it does have similar power, but don't just look at the power, look at the RPM it makes that power. The 5SFE makes its peak at 5400RPM while the 3SFE makes it at 6000RPM which means it likes revving higher than the 5S, which is better for turbocharged applications, in terms of power.

However the 5S-FE will spool the same turbo faster and make more torque.

having no experience of the 5sfe, I can say (any boost leaks not withstanding which may be clouding my view) my 3sfte does suffer from turbolag more than I expected, however when in higher revs becomes a very fun car to drive, 5.5 to 6k and it feels quite alive, boost is kicking in big time, etc.

However....I am thinking the 5sfte may be more fun if boost is coming in lower and easier. Though it does mean I can easily drive my 3sfte off boost, and still actually enjoy it. Just have to "work" for boost with it (though 2 or 3psi going up hills kicks in quickly and makes accelerating up them easier!)
