Did it have a topgun chip?

I was told it had the 160 top gun

Buyer pays shipping.

Also for sale is the Getrag 282 5spd transmission (2nd and reverse grind a little)
I am willing to remove all parts for a full Auto to 5spd swap.

I also have a spare L82 3100 complete motor from oil pan to throttle body.  Motor has never been dissembled and the crank spins freely.  I have never tested the motor though.

I think theyre referring to the adjustability of the crank trigger. But you wont have to worry about that, if you are using the tgp ecm, its not sfi.

Ahh ok, i was just told on 60degreev6 that if i use the tgp ecm with the L82 and only connect the 3x crank sensor than it will work fine since the tgp ecm doesnt know about the 24x.  do you know if that is accurate?

Thanks for the reply.  i was reading on that external crank sensor and it said it may have problems with SFI motors that check for intake timing vs. crank timing.

that may put a damper on me using the tgp ecm and wiring harness,  Any ideas?

I have a 90 tgp with the stock LG5 in it and a 282 5 speed swap.  After installing a new turbo the engine seized shortly after.  I just picked up a 3100 SFI, i am pretty sure it is the l82 due to the SFI on the intake?
Soo my question is can i swap the bottom end from the l82 to the LG5 or would i be better off throwing the entire l82 motor in the car? and would my tgp wiring harness and pcm work? and i would switch the injectors, oil pump, oil pan, and obviously the crossover with the turbo setup.  Any insight on this would be greatly appreciated as i am in need of a daily driver and have limited funds.  Thanks

Ok i got ahold of a 3.1,  Besides injectors oil pan and oil pump what else can i do to this engine while its out to either save performance or increase performance all together?

So would i just switch out like Heads, Injectors, and intake out of the tgp motor??

I recently purchased a 1990 red tgp 5 speed swap.  when i got it the turbo was blown bad but the car still ran just smoke alot. i pulled the whole turbo kit out cleaned out the oil and custom fabbed a generic ebay turbo with a t25/t28 flange in it for approx. 225$. i got the car running and the turbo worked perfect but the wastegate wasnt opening. so i couldnt figure out why but the car continued to overboost and hit fuel cutoff. well i was driving around the other day and i over heated the car not paying attention at all i was more worried about taming the boost problem. well the engine is now seized and im not sure what i want to do from here.  I can get my hands on a stock 3.1 for free! or should i pull the TGP motor out and rebuild that?
