Engine swaps

Swaps that work in a 2gNT DSM:
  • The shortblock from the 96-99 DOHC Neon is identical to that in the 2gnt. The head is backwards, and will thus require the head from a 2gnt, Avenger, or Sebring.
  • The 96-99 SOHC Neon block is the same, but uses dished pistons which will lower compression if used. Requires 2gnt/Avenger/Sebring head.
  • 95 Neon SOHC bare blocks have vents hole cut into a shelf on the side of the block, these will need to be plugged for any 2gnt use.
  • 95 DSM 420a's and Neon D4RE's (420a) have an offset bearing notch in the main web. A new notch should be cut if you wish to use the common 96+ main bearings, otherwise you could use two sets of 96+ bearings.
  • The 95-99 4cylinder Avenger and Sebring has the same deluxe longblock as the 2gnt. This is a direct swap.
  • The 2.4l from Cloud cars is very doable, and can fit with a little modification. More 2.4L swap info can be had courtesy of our friends at 2GNT.com - home.

Swaps that do not work in a 2gNT DSM:
  • Nobody has tastefully completed a SRT-4 engine swap, it has been measured to not fit well. If you think you will be the first, just do it, then tell us how.*1
  • The DSM 4g63/4 requires a lot of fabrication and rewiring to fit. The consensus from those who know is that it is not worth it. Take our word for it.
  • The Evo 8 4g63 faces the right way, but requires a lot of fabrication and rewiring to fit. The consensus from those who know is that it is not worth it. Take our word for it.*2
  • The 6g72 requires a lot of fabrication and rewiring to fit. The consensus from those who know is that it is not worth it. Take our word for it.
  • The 2JZGTE, RB26DETT, VQ37, K24, B16, SBC, P&W R-4360, &c... will not fit without ridiculous fabrication and wiring. Don't ask us how to do it - we just don't know.

*1 An A855 (SRT-4 engine) swap was done recently, but a hole had to be cut into the hood to accommodate the motor. Ref:What do you think? 2G SRT-4 Swap.
*2 An Evo 8 swap is being done, but in the end you have a stock 4g63 and a whole lot less money. Consider the purchase of a GS-T. Ref:Swap Progress.
