2tg guru's i have a 2tg with 304 intake 288 exhaust 9.8 pistons headers and 2.25 in exhaust, with light wt flywheel will these work with the stock (2tgeu) efi set up or will i have to change any thing to make it work. If changes are required any ideas on what they would be. I currently am running 44mm mikunis with no large venturis and the car runs well with strong mid range and top end will it lose anything with the stock efi? Any info is appreciated. Thanks Greg

The stock EFI should be fine with the mods, My advice would be to get it all in and running then take it to a dyno shop and get them to check mixtures, ignition and detonation. The higher compression and extra fueling will require different mixtures and ignition to standard. The factory computer will compensate for this to some extent, however I wouldn't give it too much without getting it looked at and tuned properly.
The EFI should keep your midrange strong and really boost the low end performance. Peak power is debateable. in some cases, a natrully aspirated engine will produce more power with carbies than with efi. Peak power is usually limited by how well the engine can breath and if you have airflow meters and a heap of inlet plumbing, it can start to slow things down.
Keep us informed on how it all goes. Sounds like your gonna have some fun.

I am running efi on my 3T/2TG hybrid engine and have some pretty big cams too....
Umm, from what I have heard of the standard 2TG efi set-up it won't like many changes from standard as it's a very basic and old system, my mate Rob (aka INFERNO) should be able to help you out a bit on this cos he has played round with his efi a fair bit.
But I am running Microtech MT-4 with 3TGTE injectors, and am very happy with the result.... although it's still not tuned properly
umm don't ask me the exact specs on my cams, cos we don't know them, all I can tell you is that they're VERY lumpy, even with the efi now, and when you hit 3000rpm ya better hold on, and they seem to want to rev out a fair way too.... but my rev limiter on the MT-4 beats me to it....
but yeah, from what I have heard stock efi is not much gain from carbies....
just my opinion and experience
anymore questions just ask
