View Full Version : Part # for USDM 3S-GTE Intake Manifold/ECU

03-21-2011, 10:12 PM
I'm sourcing a JDM 2nd generation 3S-GTE and need the USDM intake manifold/ECU in order to make my swap legal in California.

Any information on where to source these two parts/ part numbers would be greatly appreciated.

The intake manifold is 17101-88385 and the '91 ST185 ECU is 89661-20761-84. The manifold is discontinued. The ECU may be available as as special order, but I kind of doubt it, and there are none in the country.

You can probably find a used manifold and ECU at reasonable prices from people parting out cars or swapping in a Gen3 or EMS. Have you looked into drilling and tapping your existing intake manifold to accept EGR? It might not be difficult.

Yeah, intake manifolds are a dime a dozen on the forums. IIRC the sticker price on a new manifold was around $800. I bet you can find one for less than $50 shipped either here or on MR2OC.com. Same with the ECU.

A USDM ECU is a dime a dozen too. You shouldnt have any issues finding a USDM ECU, and Intake manifold, and EGR assembly.

You also will need to drill and port the EGR passage into the exhaust side of your head also.

I would trade you my spare USDM intake manifold for your JDM intake manifold straight up. If I still have the EGR, you can have that too. PM me if you are interested.

If I already had the engine I would definitely take you up on your offer, but the swap won't be happening until the end of the year. I'm still just planning everything out to make it legal.

good thinking, I wish I'd done that, I would have saved a little more cash and just bought a 95 supra turbo, running!
