tazman11683 Posted November 13, 2012 Author Report Share Posted November 13, 2012 well between my injectors msd coils cold air intake and computer tuning it will be about the same Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 13, 2012 Report Share Posted November 13, 2012 MSD coils are worse than stock, injectors dont really give you more power unless you have supporting mods where the motor needs more fuel. Just cause you have bigger injectors on a stock motor, yeah youll get some, but not alot. CAI, better than stock, but not worth a huge amount of power. Sorry man I just dont see 18hp there.

Garrett Powered Posted November 13, 2012 Report Share Posted November 13, 2012 that is why get a BIN from a TGP and run the 3400 on it instead of the NA BIN. later on boost it. you will have more HP than you know what to do wit Quote Link to comment Share on other sites More sharing options...

Garrett Powered Posted November 13, 2012 Report Share Posted November 13, 2012 the 3400 does not look right in them and gm literally sales a shortblock to be used with the 3.1 top end you talking about the aluminum bow tie block? Quote Link to comment Share on other sites More sharing options...
tazman11683 Posted November 13, 2012 Author Report Share Posted November 13, 2012 you talking about the aluminum bow tie block? no its a 3400 normal short block if u go to gm and tell them u need a short block for a 3.1 or 2.8 they will show u a cast iron 3400 Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted November 13, 2012 Report Share Posted November 13, 2012 hmm odd i have never ran into any issues running the 3400 block under the 2.8 or 3.1 top ends and chevy them selves use the 3400 camaro block in 2.8 s10's as a upgrade crate motor and this junk yard motor has 80k on it this way and runs perfect i have built many 60 degree motors and have been a mechanic for 12 years at a shop and we use the 3400 block under 2.8 top ends all the time as upgrades as gm service says to do so GM does not recommend the 3400 block in place of the 2.8/3.1 block.... they may recommend the 3.4 block(93-95 F-body), but not the gen3 block. the iron-head 2.8/3.1 is gen1, the aluminum head 2.8/3.1 is gen 2, the 3100/3400 is gen 3, 3500 (non-VVT) is gen 3.5, 3500/3900 is gen 4. big differences between the generations, but for the most part, a lot of stuff will interchange nicely. gen 3 saw a vastly improved oiling system, along with the roller cam. Thats because the 2.8 heads themselves will bolt to the block, so you naturally used the matching intakes. Try bolting 3100/3400 intakes to those heads. Wont happen. Iron heads will only bolt to the 2.8/3.1 intakes. While the aluminum heads are for the 3100/3400/3500 intakes. Thats why you never had an issue. But even the 3400, several generations of that as well. the top-end stuff is essentially done by generations.... you can throw gen 1 heads on a gen 3 block, but the gen 1 intakes are pretty much your only options. gen 2 MIGHT work, but i wouldn't bother. 60V6 hybrids are a simpler way to update the engine, but in the end, you end up spending more for less, so it's kind of pointless unless you have to run your original block for some reason. that's about the only time the topic comes up on 60V6. the gen 1 heads suck out loud, the gen 1 intakes.... not as bad. the gen 2 heads, significant improvement, but now the intakes are the biggest issue. gen 3 heads are slightly improved, but the intakes are the biggest gain IIRC. it's odd how GM chooses to gimp it's engines to meet certain requirements. you talking about the aluminum bow tie block? oddly, this is also a gen 1 block. by the time it came out, the gen 2 was already well into production, but they designed it using gen 1 architecture. expensive, and only something like 50 lbs lighter.

Shifter23 Posted January 17, 2013 Report Share Posted January 17, 2013 I was wondering about the alloy block! 50lbs isn't much of a loss considering and also I was debating on picking up a gen 3 engine sometime to play with but it looks like gen 2 might be better? Either way cool to see a Fiero going Turbo someday. I kinda wished the Fiero would have been a Mclaren/Asc project but alas W-bodies got it in the end.

Shifter23 Posted January 17, 2013 Report Share Posted January 17, 2013 It may not look right, but its more power The GM swap he is talking about is listed on 60 Degree V6 in the family tree as the GM replacement truck block everything is clearly stated there. In 1999 GM parts division introduced the HT 3.4 for trucks with some improvements and is used as direct replacement for 2.8. Quote Link to comment Share on other sites More sharing options...

I know what hes talking about, and that quote was in reference to him wanting it to look somewhat stock, where as the 3400 would not achieve that................ And having swapped several cars, I think I know what Im talking about and what to do. thank you though...... Quote Link to comment Share on other sites More sharing options...
DefEddie Posted January 18, 2013 Report Share Posted January 18, 2013 3400 block can be made to look like a 3.4 I think. Biggest giveaway pretty sure is the front cover. Just use the 2.8/3.4 front cover (88+) and oil pan. I think that'll do it. Quote Link to comment Share on other sites More sharing options...
