ok so i have been toying around with the idea of doing something new and unique and decided that throwing a ls1 into a FD would fit that bill, now im goin to go forced induction with this project and im wondering what problems anyone of you have had if you or anyone you know has gone that rout with this swap weather it be superchargeing or turbo

 

The only thing I can think of with supercharging/turbocharging an LS1FD would be engine space, I'm sure you could make it work. Also, if you had a whipple/roots blower you would have to have a hood cowl. I'm sure other guys would chime in here as well.

How much HP are you looking to make?

BTW these are not my cars pictures there from some member on the forum , cant remember his name though

 

why forced induction? are you looking to have a totally unstreetable dyno queen? an LS1 with a nice heads/cam package and a few goodies will net you 500hp. a small shot of nitrous and you have a 9 second street car... what more do you need?

 

why forced induction? well i always try to do something unique when i get a project car and tought it would be a nice choice, i know space is going to be the biggest problem here and being unique has it drawbacks "$$$" haha...im wanting around 500rwhp and your right TurboLumpy i can get close to the HP im looking for with a 90mm fast intake and TB, injectors, decent cam, set of afr 205cc heads, good tune and a 100shot, a setup alot like this just put my buddy into high 10's in the quater with his 04 GTO...but there is nothing like the feel of a super/turbocharged car, last play car was a procharged 97 cobra and i loved the feel and sound after i installed the charger, and after rideing in a few turbo cars i just got addicted to the sounds and feeling of it

 

I honestly then think that the LS1FD isn't the right car for you as turbo lumpy said.

Imagine trying to get traction with a charged Ls1FD.

 

this is neither new, or unique. . .while it is a badass car in the end, you would in no way be the first, or last person to put an ls1 in an fd. the FI bit puts you in a substantially smaller sub-category, but why the hell are you gonna FI a motor like that to get 500 "measly" hp out of it. . .?

to each their own, it's your car, blah blah, but if uniqueness is chiefly what you're after. . .i'd reccomend something else ( perhaps a total driveline reassignment . . . RR perhaps)

im not trying to be the one and only person in the world to do this, ...during your day to day driveing how often do you see a FD on the street? and of the ones you do find cruiseing around how many have had some kind of engine swap? and of that group how many have a ls1 and are FI? maybe where you are from they are as abundent as hondas with fart pipes buzzing around, but i can honistly say that i personaly have never met anyone who has done it...sounds kinda rare to me

and the idea of going FI is not set in stone just yet i was just wanting some feedback from anyone who has done it

 

An LS2 with L92 heads and L76 intake along with a good sized, well thought out cam; paired with longtubes and a good flowing induction system and you should be able to see damn close to 500 RWHP for way less then forced induction would cost you. Then throw a 100-150 shot at it and you're in the 600+ RWHP club.

F/I is neat and all, but utterly unnecessary in a car like this, unless you're shooting for the 700-750+ RWHP range.

 

Yeah, personally I'm thinking about swapping in a 4g63, but the damn LS1 is such a good way to get that kind of power into the car, I'd have to agree with digitalsolo. A nice shot on top of a good N/A setup would be awesome.

Those damn V8s keep tempting me, I'll probably end up with one instead of the turbocharged 4-banger. Plus, a lot more people have already done the LS1 swap thing, so it would be a lot easier in the long run.

 

I like DSMs and 4g motors myself, but I just can't get past the fact that specific output per liter to get the 500-600 RWHP I want is a lot of stress on that little motor, however stout it might be. On equally well designed engines, more cubic inches is going to allow far less stress on a larger engine then a small one. Pretty simple physics.

Nothing against the oddball and small motor swaps, your car, your perogative.

 

Yeah, well the only thing that I really don't like about the V8 swap is the sound, but I really think I might just get over that. The power output, 6-speed, and relative straight-forwardness of the LS1 swap is really almost too much to pass up.

I really don't think 500 whp for the 4g63 is really pushing it THAT hard, but then again, I think it's probably a lot easier to hit 500 whp on PUMP with an LS1 than it would be with a 4g63. It's not impossible, but you really have to know what you're doing to see that on pump gas. A simple N/A LS1 with some mods that would yield 500 whp on pump sounds a lot easier.

 

4g is what, 2L, correct?

So, 250 hp/liter vs. 87 hp/liter. Which do you think is stressed more?

The cylinder pressures and RPM necessary to create that power is going to be higher on the little motor, period. Considering both motors are very stout, it just seems logical to me to go with the displacement. I can always stick a turbo on the LSx later if I want to, not that it's necessary.

As far as exhaust note goes, I guess whatever floats your boat. I've never cared for the thousand angry hornets sound of the little turbo 4 bangers myself, though it's better then the nasty burbling sound my 3.8L buick motor makes. Goes fast, sounds like ***. That should be a license plate. LSx and SBC motors sound great, though I like the sound of a 5.0L Ford better (the sound, NOT the engine).

 

Nasty burbling sound, lol. Well one of the things I like about the 4g63 is it isn't buzzy or hollow-sounding like a Honda B-series. It's much deeper, a bit subdued, but a lot healthier sounding.

Anyway, there's one engine that beats them all when it comes to sound and that's the 20B. And I may just end up one of these days building myself an N/A 20B in remembrance of Dave. He always had all these cool ideas for N/A rotaries.

 

Heh, if I ever buy or recommend an engine based on how it SOUNDS vs. how it performs, I'll walk away from performance motorsports permanently. On the list of important details, that's damn near the bottom of the list, almost as far as the engine being "unique".

Anyway, this topic has gone far enough from it's intent I think.

 

Well, don't get the wrong idea. I wouldn't do a 20B solely because of how it sounds. I'm just saying that IMO it's got the greatest note of pretty much any engine. Which is a bit of a concern for me, considering how I'll have to live with the engine sound every time I drive the car. But honestly, I've already got one fast car, so maybe I don't HAVE to have the fastest thing on the road.

But I've always wanted to try an N/A 20B (hopefully around the 350-400 whp level) with maybe a 100-shot on it, or larger if possible.

At any rate, I need to get the car first, and THEN worry about picking an engine (hell, FIRST I need to save money). Right now my prime concern is the mortgage. So rather than continue this benchracing dream, I'll let the thread continue...
