dsgrntld187 Posted June 26, 2004 Report Share Posted June 26, 2004 Ok guys, I got some questions about engines.. Is the 3400 a rebored 3100? Whats the difference between the 2000+ 3100 and the 94-99 3100? Is the 3500 a 60 degree v6 and if so was it based off another 60? And finally: Will a 3.1L MPFI drop right into a Fiero with a 2.8L? Thanks guys Spencer Quote Link to comment Share on other sites More sharing options...

Thanks guys Spencer 1. Yes the 3400 has a bigger bore, but IIRC the block is slightly different because of the bigger bore. 2. The 2000+ 3100's got the 3400 heads which flow more air. 3. Yes, but I think it's an all new block. 4. Yes it should Quote Link to comment Share on other sites More sharing options...
Intimidatorz34 Posted June 26, 2004 Report Share Posted June 26, 2004 3. Yes, but I think it's an all new block. Id hope it is.....but from what I saw, it looks exactly the same, Distributor o-ring and all :dammit: Quote Link to comment Share on other sites More sharing options...

Thanks guys Spencer 1. Yes, that is why alot of guys do the 3400 swap from their 3100s. 2. Gains in HP, 2000+ is like 170 and 94-99 is 160HP. 3. Not sure man, I don't know enuf about it engine. :? 4. Hell if a 3.4 can I'm sure a 3.1 can. Quote Link to comment Share on other sites More sharing options...
dsgrntld187 Posted June 27, 2004 Author Report Share Posted June 27, 2004 Can any of you show me a website that gives info about a 3400 swap? I'm heading to the J/Y tomorrow (mostly for a new hood and HUD, rust has gone through the whole front of it now), and maybe I can check about getting a 3400.
