Turbo Grand Prix 3500 swap

[Jonpro03]

The time has come. I just bought an LX9 with 87k miles for $200. I am fully aware of all of the challenges that will come with swapping this motor. So I am going to start with the most obvious and maybe most difficult one; the CPS. I know about the ECT from wot-tech but I want to avoid spending that $150 bucks and they're out of stock anyway. I was wondering if the crank pulleys were interchangeable. It would make my life a lot easier if I could swap the crank sensor and the crank pulley.

Thanks!

the reluctor on the balancer is the 24X, which is the one you wouldn't need running on $8F.

up until the 3500, the 3x00s had a 7X reluctor inside the block on the crank, and the 24X on the balancer. i believe(me being a 3500 noob) the 3500 still has the 24X on the balancer(or maybe it's gone entirely?), but the internal reluctor changed to a 58X(?). i believe there have been a few people that have had the 58X removed and the 7X pressed on in place of it, but that requires tearing apart the motor.

it dosent have the 24x on the balancer. you have to use a 3100,3400 balancer and sensor so you can have 24x

Maybe I wasn't clear enough. I know that the LX9 crank pulley and CPS won't work on the LG5 harness and computer. What I want to know is if I can take the CPS and crank pulley off of the LG5 and put it on the LX9.

.... jon, the LG5 doesn't have a reluctor wheel in the balancer like the later SFI motors, just the internal 7X ring on the crank.

Isn't there 7x and 24x on the balancer of a 3100? I could have swore that there was. Maybe Im thinking of the evil 90*

So I am SOL unless I can get a hold of a ECT. Which are currently out of stock at wot-tech

[robertisaar]

on a 3x00 balancer, just the 24X reluctor. and yes, the 90s have a dual pattern one in their balancer, and no i don't know if you could use it or not.

I am seriously considering building a megasquirt. I have build a MS2 and helped to install it into a camaro. I see there now is a MS3. Has anybody used an MS3? I can see a lot of upgrades such as Sequential FI and usb interface.

I might just stick with a MS2 though since I'm familiar with it and its a lot cheaper. MS2 is about $250 and MS3 is $370

I will see how long I am going to be out of the triggers. Might be next week if TCE has some still.

Go to work pulling out the LG5. Hope to have it out by tomorrow before the new engine arrives.


What do you think about the intercooler? Good spot?
