TurboSedan, I never called your idea STUPID. I asked you WHY. Knock it off. I wrote that Forum description. I'm very well aware of what it says.

Turbo.....

if your getting a L27 SSE.....why dont you consider Boosting that motor...it has the same crank as a Series One L67, granted the Pistions and the rods are different, and then you still have the trans to deal with, BUT Boosting the L27 and Even the older LN3 has been done....

with the money you have saved by not having custom **** fabbede get the trans built to handle the power, and have one hell of a car

that'* certainlly still a possibility that i need to look into more. for my goals the engine will definately have to be built up. for example, what is the 'L27' CR? is it higher than the Series I 'L67'? are forged rods and pistons available for the 'L27'?

i think either way the trans, whether it be 4T60, 4T60-E, 4T65-E HD would need to be built up to handle 350-400whp. on the other hand a Getrag 282 or 284 could probably handle it no problem with just a good clutch.

the big thing that makes me prefer the turbocharged 3400 over a turbocharged Series I 3800 is the tuning aspect. tuning would be so easy in comparison to tuning a tubocharged 3800 - that'* kind of unchartered territory as far as i know, that is; turbocharging the Series I 3800 with the factory Series I 'L67' definition file and editing the .bin file. i'm sure some major changes would have to be done to the .bin file in the chip to get it to run right. that'* all been covered with the turbocharged 3400 using modified TGP code (chip) in the 1227727 ECM & using an older MPFI 3.1 batch fired engine wiring harness. there are alot of people on other forums that have been doing this with great success.

however, the big thing that makes me think turbocharging a Series I 3800 would the way to go is of course, the problem of mounting a 3400 into an H-body. i'll just have to do what jr's3800 suggested and yank 3800, lower the 3400/4T60 (or 282) down into the engine bay with a hydraulic cherry picker and see what needs to be done. if i can't find the bracketry and/or fabbing brackets looks like wayy too much of a hassle to bother, than tubocharging the Series I 3800 it is.

thanks guys.

TurboSedan, you can quit taking shots at people in this topic, and we'll stop deleting the posts.

Stick to your topic.

first, I think a note should be made at whether you are referring to the 3.4 DOHC or the 3400. I think many people might have lumped the two together as the same motor, when they are infact, not.

Second, if you plan on tackling this, you'll have to remember that tuning the 3400 more because you have the weight difference to deal with as well. while this might not be that big of a deal, it is a consideration.

I think a boosted L27 would be a fun project personnally and i don't think the tuning would be too hard. GMTuners can burn chips for the series 1 from what I hear, so they should be able to assist.

The one thing you have to remember is that basing assumptions off your regal may get you in trouble. The regal, while having an L67, is still a W-Body, so there are differences from the bonneville and other H-bodies. I've owned a 2000 Regal GSE, so I have experience in this first hand. The actual L67 itself has some differences that need to be looked at too, such as oil filter neck and the afore mentioned mounts.

So I would probably say that this is doable, I just wouldn't rush into it. It will probably require a lot of time and effort as well. so just be prepared

You know, I've talked to TS personally on the phone, and he really is a great guy with a lot of know-how. I know you guys stand behind the 3800, but he'* very loyal to the 60-degree V6s and I believe he has a lot of parts for it. As many of you know, I love this club and it has a lot of really really good people here. I have never disliked a frequent poster before. Though, why all the hostility? He didn't ask for people to dog his idea, he asked for suggestions. I know everyone has a ton of experience on this board, but instead of sticking to your own agendas, why not help him with the swap? I mean, I've heard of people swapping B16s into Accords, so going down to a smaller engine isn't THAT crazy of an idea. I'm not going to go any further, because as I said, I love this forum and am very loyal to it, but I really feel like we lost a great member

People raised legitimate questions about his plan, as swapping a 3400 in place of a 3800 didn't make a whole lot of sense, given the loss of available power / tuning as well as dramatic amount of fabrication required.

After this was pointed out, he got defensive and (IMHO) rude to both Willwren and 95naSTA, who were simply trying to point out that
a) it'* going to require a heck of a lot more work than what it sounded like he thought it would, and
b) there'* more potential in a 3800 than the 3400.

He was pretttty uptight that someone had a different opinion than him.

Personally, I started in the thread because if there'* one thing that really gets my goat, it'* when someone asks for help or wants to know what'* involved in something, and as soon as someone tries to tell them, or question their plan of attack, rather than thank them for their opinion, they go off on them.

Now, as JR said - if he wants to do this, that'* fine. No one is calling it stupid (though we question the value), but if he wants to do it, he'd better just get a hold of a welder and plenty of raw materials, because he'* going to be custom fabricating pretty well all of it.

And if he wants to do that, that'* fine - it'* his car and his motor. We'll be happy to watch and look at pics, and pat him on the back if/when he got it running. But when he asks our opinion, it'll be given.

On this Forum, we invite discussion and debate. Not hostility or argument. Nor personal shots.

Enough of the character references, I've spoken on the phone with him too. Great guy.

Get back on topic.
