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!

It all depends on the turbo you're using.

3S-FE will surely have more lag, but don't expect the extra .2L to knock off a full 1000RPM of spool up on the same turbo. I think the 3S-FE is also a bit lower compression (9.3:1) than the 5S-FE (9.5:1) so there's a little more spoolup difference there. However, the lower compression allows you to turn up the boost a little bit higher than the 5S-FE will on the same octane fuel and same turbo.

You should look into putting on a GE head and pistons in in the near future... it's a lot easier to do given you've already got the 3S block. A 2nd gen head should bolt right up.

If you feel your turbo is too laggy it probably means it's too big. In my case, my turbo comes alive when I step on it at 2800-3000RPM, and the car pulls up until 5800 and then it falls flat on its face.
