ok so far i been doing a ton of research about which engine would best fit my wants and needs. So far im looking into chevys 6.0L LS1. The only bad thing about, is that it will be ateast 130lbs "estimated" heavier than a stock TT FD. It has huge potential for power. it comes stock 370 or 380 tq and upgrades are the same as the other models. What do you guys think??

Where did that weight figure come from? I've read numerous times that the iron blocks only weigh 80lbs more than the aluminum and it's been well-documented that that combination weighs a few lbs LESS than a stock TT rotary and it's supporting equipment. Honestly if weight is your primary concern, use a complete aluminum 5.7. A cam swap will get you the same numbers you're looking for and save you those 80lbs.

duramax diesel. LOL most cost effecient.

lol yeah a diesel would be great. i got the estimated weight from ls1tech and torque central while i was searching around. the iron block 6.0l would be cheaper. the 6.0 block is the same as the 4.8 and 5.3 truck engines. its just bored out and stroke more, obvious. weight is not my primary concern whats 80 more lb really going to do. Looking for something that will be ez to gain huge power, ez to drive, good gas milage, will have a ton of potential, and cheap =D. So far i have seen bare blocks w/ internals online for around 200-500 bucks. this would be the best option since i would like to upgrade the heads, shallower oil pan and the rest of the goodies. Trying to pay for just what i need and nothing more. its going to be a DD street car. Wonder if anyone has done a diesel into an FD.

Same crank as a 5.7 liter LS1, just bigger bore and pistons to go with that said larger bore.

As far as cheapness, it might not be - demand is starting to get high for the truck motors, its not a very well kept secret, lol.

As far as diesels... I fail to see how they would not be madly expensive by themselves, plus youd need to do a IRS pumpkin swap so that you would have longer gears. 4.11s and a diesel dont mix!

sudseh

if you're going diesel, you could always look at the audi diesel v-8's and v-6's they have over in europe. those things are amazing.

AF1

Those audi diesels are expensive as hell. The 6.0, i notice are getting up there in prices as a pulled and running engine. There are also a lot of cheap unfinish projects on ebay for those engines.

AF1

Do you guys know how much hinson charge for the 6.0 he sells?

GUITARJUNKIE28

i'd do a diesel for ****'s n giggles.
only problem is unless you swap out hte rear end, your top speed will be somewhere in the neighborhood of 70-80 mph

and how come nobody mentions chevy's (gas) truck motors? they can still put out 400+ hp, and you can pick them up with the computer and crap for like $1500-2k, instead of the 3-4k for an ls1.

since you're gonna be spending money anyway, put a blower on the truck motor and put out more power than the ls1 for less money

You mean Americans really do make good V8's all the chevys, fords and mopars I have seen and worked on have been outdated pushrod crap!

GUITARJUNKIE28

don't knock pushrods. i had 330k on my camaro's engine when it finally kicked the bucket.

and if you can design lightweight pushrod v8 that has 500hp and gets 27 mpg, go for it.

oh yea...stick a warranty on it too

GentlemenVII

well as far as piston engines go v8 = crap unless its DOHC or has VVT, come on there are boxer 4's pulling more and are more robust EJ207's what about SR20DETT I4's or RB26DETT and 2JZ I6's even an VG30DETT v6's

AF1 - You are getting a lot of crap here from people who read the car magazines but never worked on a swap. Listen to guys like CrashTestJoey - he has actually done the swaps and knows what he is talking about.

If cost is a consideration, the small block Chevs and Fords are excellent engines, without all the complexity of the overhead cams, etc, which buy you nothing unless you really need something to brag about. If this is for the street or for drag racing, a pushrod engine is fine, although you would want to get something recent enough to have roller cam and roller rockers. If you plan to race it at Lemans, then you should drop in a Nissan Sylvia turbo motor!

The Ford 302/5.0 is about 75 pounds lighter than a Chev 350, but there is a lot more performance equipment available for the Chev. Either one will easily make all the horsepower you want for street use, and be very reliable and long life.

rajahFD

yeah, motor's from the 80's are outdated.

GUITARJUNKIE28

hey, the vette's got a quad-cam 350 for a couple years. didn't do any better than pushrods, though.

i agree you don't want pushrods flappin' around when you're turning 8k rpm, but stock-production v8's don't turn 8k rpm. 5500-6kish, a bit more for some, but that's ballpark. the advantages overhead cams give, in terms of higher revving stability are pointless at that rpm range.

it'd be like using a peripheral port engine and never revving above 6k.

My duallie has 4.11 gears. Need your house moved?

The 6.0L i was talking about is a chevy truck engine lol. Doing a SR20 or RB25/26 wont have as much potential as any high displacement V8 and it will cost 2x more for the power, plus paying for the gas lol. Those fools reading the magazines need to wake up and realize that america make really great motors and are cheap. most guys spend 2x or more spending on engine upgrades and will still not reach the level of say an LS1: 4.8, 5.3, 5.7, or 6.0. Parts are cheap and tons of available upgrades. Its like having a B16 or B18 series but with upgrades that acturally makes the engine better hahaha. If those guys acturally spend time checking out what the V8 guys are talking about they might acturally learn something. Built internals + boltons = 600hp/600tq ez. then u have room for boost =D. Cheapest way for boost would be a SC. A turbo will have more potential but who is going to need that much power. I forgot tunning also. More cylinders = less piston movement and longer life with high power. Im pretty set on going with 6.0L LS1 LQ4 or LQ9. The LQ4 would be cheaper but 10 less hp stock. This thread was for those guys who have expierence and knowledge of american beast muscle. Just asking for their opinion on which v8 are best bang for the buck for 600+ power. Any more flames about american v8 are crap is just retarded. I been around guys doing Rb26 into their s14/13 in the states or doing an Sr20 or the other hyped up engines. These are close friends not guys i just heard about on the streets. The problems and money they spent was not worth what the outcome is. Thanks for the guys who are posting and know what they are talking about. You other guys who dont have a clue, go get educated yourself on what the redneck guys are doing around the block before u start criticizing.

GentlemenVII

You missed my point. I am talking about kiloWatts per liter and VE of diffrent motors and GM is the most unlikly place you will find real enginering trust me I have been working the automotive feild for years. I work beside a GM Grand Master Tech and a VISTA tech look it up. Lori used to work in the sweedish HQ


And back to the topic if you want an Amarican V8 get A VETTE!!!!!! not an rx-7 the car was build around a rotary if you change that it will Sacriface the cars dinamics!!!!!!! the VETTE was build around a V8 so buy that!!!!!

GentlemenVII

P.S.

V8 have more stress on the crankshaft, have more vibration (need more damping) and more friction. plus they are build loose.... I won't waste my breath on anymore advanced topics on my point. It will fall on deaf ears anyways

AF1

Are u serious? im not going to keep it 100% stock. And im not talking about kilowatts per liter. if i wanted kilowatts per liter i would keep the rotary. I want cheap, ez, power, and reliabilty. People say that GM suck because they have huge displacement engines but dont make enough power to match the volume. i bet those same people dont look at the price either. getting everything without sacrificing too many. If i wanted a Vett i would of saved up and gotten a vette. But the FD is good looking, lightweight, great handleing, its cheaper, and getting full coverage insurance for a 21 year old in germany is cheaper here. they go by the engine size not type, eg, twin turbo. sport , coupe. I love motorsport, rx7, and rotarys. I just realized that i been lying to myself that rotary engines are the best because they have small displacement and produce huge power. But after 4 years of owning 2 FC, 1 FB and how 2 FD i came upon searching for something better. The rotary concept works. but its not the best. Maybe it needs more development, but still love the concept. High displacement V8 in a small block is great. Being a little longer than a 4cyl and shorter than a I6 cyl. Have u ever seen an RB25 or 26 in an s13? u hardly have room between the radiator and engine. I dont know how a 2jz would fit an FD. The VQ30 have taller heads, being dohc, and is wider than pushrod V type engines. The stock turbo system on them will be hard to make fit. Why would anyone who love motor sport rant on something if it makes that vehicle better? is it just because it goes against your steriotype of the guys with big trucks and redneck cars?

Do we have a "who gives a ****" smiley on this board?

How about you and I race. You're not afraid of a junky old worthless Corvette pushrod engine in an RX7 with no soul, are you? I don't work in the automotive field and even I know that the first one to the finish line wins

P.S. ******* Canada. Why haven't we gone to war with them yet?

AF1

Damn you're mean, but i can see why since u guys get a lot of flake for doing the swap. Its just common sense. ok The Chevy LS1 6.0L best bang for the buck?...anyother engines?

Nihilanthic

Yeah, and whats the outer diameter of the tires on that vs those on a FD?

GUITARJUNKIE28

did you bump your ******* head?

ls1 in a camaro: 320 hp bone stock (easy 400 smog-legal hp with cam, intake, and exhaust), 30+ mpg when you cruise.

renesis in an rx8: 230ish hp, but only 150-175 makes it to the wheels on the dyno, 19-22 FREEWAY mpg....IF it's driven on tippy toes.


yea, american's really suck at engineering
i don't care where you've worked for years, you've still got your head up your ***. you think just because it doesn't spin 9k rpm's it doesn't have incredible engineering behind it? let's see you design something from scratch.
