Project 2 years in the making, 3rd gen 3SGE + T into an ST (pics soon) Options

[scothaniel]

About 2 years ago I started to collect part for a new project - putting a 3rd gen 3SGE into my wifes 6th gen Celica ST. Well, after a short bout with unemployment and a long home remodeling project, I've finally started on the engine swap.

The motor was dismanteled after receiving it, and the stock 10.5:1 cr pistons were replaced with stock turbo pistons. Everything else internally was kept stock. Since I am only looking for power in the 300 - 350 HP range, I could have used the stock tranny, but since I had a spare MR2 turbo trans sitting around I decided to use that. I found an stock LSD differential on the web, and had the guys at Team Rip (teamrip.com) install the diff and "clean up" the gears.

The turbo kit uses a modified Greddy based knock-off exhaust manifold along with a 14b Mitsu turbo and an Evo III O2 housing. The O2 housing comes a little too close to the 3S's AC compressor, so I'm using the A/C compressor from the ST with the comp wheel off the 3S compressor. Once the engine has been broken it properly, I'll probably swap out the 14b with a small 16G or EVO turbo.

Last weekend I picked up the GT4 super-struts from Martin and hope to have the full shocks / brakes installed this weekend (if the bushing collars ever come in from the dealership).

I'll post a couple of pics shortly.

Yeah, I had to add some bling to the bay. Next will be cleaning up the wastegate - maybe some black paint to make it right.

I repinned the ECU connectors to the new ECU - had to do a little cutting and soldering there too. The most difficult part was getting a 3SGE EFI diagram in english - everyone one I found was written in Kanji. I did have to add a couple of wires for the 2nd air-temp sensor and the Turbo VSV. The wiring for the fuel pump is a little different too - the turbo ECU's have a low and high fuel pressure switch (via relay) to bump up the fuel under WOT, but the non-turbo cars only have 1 setting. I left the wire disconnected at the ECU, so I may end up with a code later on. Easy enough to fix.

Found the manifold on Ebay. It was supposed to be part of a 3rd gen Greddy L2 turbo kit - but it was a shotty knock off. The L2 turbo's have a circular 2" flange, so I just bought a standard TD05 flange, routed down the L2 flange. and welded the TD05 flange right on top of it. It wont fit a T3 turbo, but If I ever decide to switch over I'll just cut this flange off and weld on a T3.
