Carotop Posted December 18, 2004 Report Share Posted December 18, 2004 So I was at my auto class and this kid was like "Do you wanna race me" and I was like sure. So he's got a older Chevy conversion van and I think sure I can beat him, I was totally wrong, he freakin womped me. So um would a 01+ 3400 be a good swap? I just don't wanna be part of the crowd with another L67 swapped Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted December 18, 2004 Report Share Posted December 18, 2004 well...YES...a 3400 would be a very nice swap...it deffinaly isnt a L67 but with some mods you should be able to run in the low 15's or maybe better...i dunno...and the best part is...its pretty much a DIRECT SWAP...you can use your transmission and computer...though, from what i've been told...if you use your comp...its best to have it reprogrammed for the 3400 BUT, it will run fine without being reprogrammed...another good thing about the 3400 is that they are pretty cheap...

93CutlassSupreme Posted December 18, 2004 Report Share Posted December 18, 2004 yikes that cutty must have some problems. no, it's just probably a 3.1. that's usual performance. Quote Link to comment Share on other sites More sharing options...
Heza Posted December 18, 2004 Report Share Posted December 18, 2004 my buddy had an astro van with the 4.3 and a two adjuster in the cab. that thing would roast tires like no tomorrow! Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 18, 2004 Report Share Posted December 18, 2004 yikes that cutty must have some problems. no, it's just probably a 3.1. that's usual performance. Plus he has the specific '93 SL package (SLow) I think GM detuned the 3.1 for '93 Quote Link to comment Share on other sites More sharing options...

dbtk2 Posted December 18, 2004 Report Share Posted December 18, 2004 MPFI 3.1's are pretty ballsless. I drove my sisters '93 GP LE to get some brake pads & rotors for it one day and holy hell was that thing ballsless. When you stand on it, you can't even tell your at WOT. However, my friends '93 Lumina ran very well for a 3.1 with 180k on it. He had some offbrand air filter on it, and a 2.5" exhaust. He also kept it tuned up good and everything and it would walk my friends '94 Buick Skylark 3100, which isn't really that slow. That is the fastest basically stock N/A 3.1 I've ever personally seen. Obviously with a cam, ported intake manifolds, and stuff like that they would be a little quicker. Shawn Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted December 18, 2004 Report Share Posted December 18, 2004 About the only problem you'd run into by swapping in the 3400 would be the mounting of the EGR. You'd have to get an upper intake manifold from a 97-99 3400, and make an adapter plate for your "digital" EGR to fit. You'd also probably have to get throttle and cruise cables from a 3100-equipped W-Body. Go over to 60 Degree V6 dot com . They have some good write-ups on how to swap in 3x00 motors in place of the older 2.8's and 3.1's. There was one write-up in particular that I remember where they did a 3400 top end swap on a 93 GP 3.1 (basically leaving the block in place and putting on the heads and intakes from a 3400.) I think you could follow some of that write-up to guide you in swapping in a complete 3400... Quote Link to comment Share on other sites More sharing options...
Jcrow Posted December 18, 2004 Report Share Posted December 18, 2004 What engine does he have in that van! I'm surprised! You said it was a conversion van? With that wind blockin raised roof? Maybe some 3.1's are faster than others. Mine beats my buddies '04 FX4 with 300hp. And I had 300-400 lbs in the trunk. Quote Link to comment Share on other sites More sharing options...
excelsior Posted December 18, 2004 Report Share Posted December 18, 2004 well i said it must be weak because my 2.3 sohc grand am was able to beat a 4.3 astro stock. But then again it did manage to bring down a couple 3.1 w's....and i did have some mods done to it(had mods on the car & had a h.o. q4 swap lined up b4 the car got hit) Quote Link to comment Share on other sites More sharing options...

Carotop Posted December 19, 2004 Author Report Share Posted December 19, 2004 I've heard some bad things about the 3.4 and I hear the 3400 can take tons of boost. I'm pretty sure there is a problem with the Cutty it just hasn't been right for the last month or so. I took the intake off it the other day and I noticed a total dfference when I drove it. I might have screwed the tranny doin burnouts every so often and I was sure slippin gears the day I raced the van. So it might just need to be tuned up and maybe I'll just work on modding the 3.1 for now. Quote Link to comment Share on other sites More sharing options...

Carotop Posted December 21, 2004 Author Report Share Posted December 21, 2004 Yea I'm a stupid punk kid I know. But the EGR just runs exhaust back into the intake to cut down on emissions and since MN doesn't check anymore I can go without an EGR. It's all in the art of simplicity!

terryk2003 Posted December 21, 2004 Report Share Posted December 21, 2004 ...well, i just read about your tranny slipppin....i'd fix that FIRST off...i've never really heard much about boosting a 3400...don't know where you read that...if you wanna put a turbo on something...why don't you get a TURBO 3.1?...and...i dunno what "BAD THINGS" you hear about the 3.4...the biggest problem is maintenance...and that DAMN leaky O-RING...but, other than that...is supposed to be a pretty good motor...i'd say a w-body would prolly be faster with a 3.4 than a 3400...BUT, oh well...whatever...you change your mind too much...

gp90se Posted December 21, 2004 Report Share Posted December 21, 2004 ill play along. the EGR valve needs to be shut off with the memcal before it can be removed, then you'd need a blockoff plate on the intake and a plug on the manifold. You really arent loosing any power with a modern EGR valve. With that said, your manifold will run cleaner in the 1 runner its mounted on.

Carotop Posted December 21, 2004 Author Report Share Posted December 21, 2004 Well I'm stickin with the 3400 for good I think. I've been reading up on it. Go to 60degreev6.com and go to 3400 performance they have a whole section on boosting it. Quote Link to comment Share on other sites More sharing options...
