This year will be my fith year in a row attending the supra nationals. Last year it was the 700hp mr2 the year before that I was running 9's in black hardtop supra. This year I'm attemping something new. I plan to be the first with an LSX powered IS300. I've been daily driving this lexus for the last year and honestly its a fun car in 100% stock form. You can drift around turns with ease or beat the local honda turd in a drag race. But when it comes to having balls it has NONE.

I plan to change that and do it in less than 30 Calender days. Wish me luck!

Old motor is out.....now I need somewhere to put it.

Engine Fits but needs a GTO oil pan and some cutting

Fits pretty damn good :)

Found some time this weekend to weld the oil pan. Inside and out


Fabbed up some mounts today. Now I still need to do the trans mount.

The Mr2 looking sad waiting to be picked up.

Today I made some brackets for the abs unit I relocated and found a spot to hide teh ecu. I also dove into the wiring a little. It looks bad but it should be easy and just really time consuming. I plan to spend 3-4 days on wiring alone. Good news is it looks like the stock radiator will work and the fans run on their own circuit.

Its a ton of wires on the wrong side of the engine bay. (the stock ecu was here)

Lucky me...I had some fitting left over from the ls1 rx7 that will work. russel makes these 16mm fittings for a camaro.

I plan to make a nice cover to hide all this stuff :)

Pray for me....headers will be a fun 30+ hours of fab. BTW those are the stock IS mounts

With less than 1 inch to spare

Lsx means any ls based motor like the ls2, ls3, ls6, ls7. I do plan to keep updating the thread with videos. My deadline for the meet is march 19th so I'm sure vids will pop up soon.

The DGR mounts are CNC machined and use the corvette pancake mounts. They also cost in upwards of $500. I fabricated my mounts before I knew about DRG and honestly I would have anyway since I already have a tig welder and I used material I had sitting around. So its like they were free ;).

wow i am super impressed, and i think the LS1 IS300 takes the cake compared to working on a LS1 Camaro. All I can say I would not want to install and or fab up headers, props to you and your build and I know I do not have tha guts for something like this.

Sick ride man!
