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!

Thought I would swing by and update, engine still running fine, passed uk emissions and mot with no advisories or fails. Have an oil leak from oil feed to turbo, only minor, just need to get at it to seal it up.

Need to sort out tuning still, as wot is 10 or lower afr, so overfuelling, but not often in high boost. Have a boost leak somewhere, but boosts happily 1-5 and pulls along nicely, and goes 8-10 on wot with no det as yet, but to be fair not often in that, and then only for brief period. Off wide open fuelling looks ok, stoic until start hitting boost then drops to 12s in low boost, not wot.

When boost does kick in though, shifts somewhat

tuning is proving tircky though as open loop seems to dump fuel like crazy, so will need I guess to use throttle position to pull fuel at 80-100%, though this feels wrong!

But assuming over fuelling is happily destroying the sports cat....

Drives almost stock off boost which is nice, though exhaust is VERY loud, only the back box and cat on it.

If this was tuned properly it could go pretty high I reckon...but happy to take it slowly and tinker
