Toyota MR2 Message Board - View Single Post - 3S-GTE USDM Turbo Engine Motor installed... Couple Questions

JeezyMister2 · 10-13-2009, 07:49 PM

Hey guys, well I finally reinstalled my motor. Weird stuff, though. When I have the AFM plugged in it won't crank over unless I give it some throttle. When I unplug it, It starts, and runs roughly.

All my vacuum lines appear to be good. But, I don't have a downpipe installed at all because it's at the welders getting a kink put in it. Do I have those two sensors just dangling. Is there any vacuum leak tester tools other than a boost guage?

Anyways , compression is 182 across.

Modifications are as follows: Bored .20 over wiseco pistons, machined head, Presicion sc61 t3t4, Wastegate ( with no hoses on the wastegate fittings ) Everything else appears to be firm , no open vacuum ports )

Could the downpipe have anything to do with it? I have no crossmember on with no back mount. Also, I'm sure my system hasn't been fully primed. What do you guys think? Any opinions are appreciated!

Joey.
