LS1-T Questions

[redtop91]

Being the lazy bastard I am I've decided that the "easiest" way to make a fun, streetable, 500whp S chassis is to go with an LS1 and turbo it. I realize that an LS1 can be made to that power without forced induction, but once again I'm lazy and the most I really want to do internal wise is POSSIBLY a cam swap. Being an NA motor I realize the LS1 won't take kindly to a lot of boost and being so large, a fairly large turbo will be needed to keep EGTs reasonable. So with those facts in mind, I want to keep plumbing relatively simple for this setup which would suggest a single turbo but wouldn't the manifold be tough to find? That being said 2 smaller turbos would be relatively straight forward but is there even room for twins in an LS powered S13's engine bay? Any input is appreciated. And someone buy my SR

[WDRacing]

In reality, the remote mount turbo will be the cheapest and easiest method. If that's not an option then a single under hood would be far easier then a set of twins. The manifolds will have to be custom though, regardless of running a NA motor or FI motor. Except for say Hinson and another company or two jumping into the market. But they don't make turbo headers...

Another option is a Centrifugal SC or a Roots style SC. Personally I won't ever recommend a Centrifugal SC to anyone because of personal choice. Boost rising with RPM to me is awful. The roots however makes full boost by 1900-2200 rpm. This will require the hood to be modified though. Which IIRC isn't an option you want to consider.

When you reply to this, give me a budget and what you're willing to do as well as not do. Also, who's doing the install? Are you buying a kit for mounting etc?

For you Ry the remote is the best bet IMHO.

Well I will have an NA LS1 for awhile before I boost it in any form so for just boost I'd say my budget is around 5k which is just a shot in the dark. I have no clue what the pricing is for LS1 parts is. I'd like to keep the swap between 8-9k if at all possible. I can only JB weld so any fabrication requiring welding will be delegated to bolt on kit parts from Hinson. I will be installing anything and everything physically mounted and any physical chassis modification like enlarging the transmission tunnel and wiring I can do. In short, no fabbing, everything else I can handle.

Edit: Where would I put a remote mount turbo anyways? There is no empty space in an S13 under carriage. I guess you could run them inside the car itself but it'd be hot as f*** in there.

how much you want for your sr?

[redtop91]

It has rod knock...

[WDRacing]

There is always a spot man...

[zzcoupezz]

It has rod knock...

soooo......how much you want for it.

[redtop91]

Hmmmm lemme see how much blocks go for. Did you want the wiring harness and transmission and FMIC?

[zzcoupezz]

what all do you have on it? im interested in atleast the motor and transmission. i thought you had an upgraded turbo also.

[OutToWinPAHC]

You dont need to force induction to make 500+ horse. Heads, Cam, Intake, TB will get you there very easily.

Trick Flow even sells a 515 HP top end kit

[redtop91]

Yeah I realize that and it may be the path I take but I'm a boost junkie.

My turbo is sold. All I have is an SSQV, polished piping, and a Greddy VSPL FMIC.

[cnichols]

I'll have to agree...if you want close to 500, all you need internally is a cam. Heads, full exhaust, FAST 90 intake, 90mm TB, crank pulley, and a good tune, and you're close. If, for some reason, that's not enough throw a small shot of nitrous on it.

A turbo would make things SO much more complicated and expensive for no gain (other than eventual potential). More parts, more heat, more things to go wrong.

[TheOne]

thats when ya go with a kennebell supercharger, its a positive displacement supercharger that will give ya enough boost and torque starting low in the rpm's to not get anymore traction than a stock ls1 in an S13:).

well then how much for the vspl, piping, ssqv, motor and transmission?

I've heard from some of my Chevy buddies that Nitrous kits don't fit the larger TB's and a custom setup has to be rigged. True?

Hahaha KB's are teh **** but I don't think it'd fit under an S13 hood. Hood clearance is a big thing for me here. If it doesn't fit under the stock hood, I'm not considering it.

I'll be pulling it over Thanksgiving break and seeing what condition it is in. I'll let you know a price once I determine if the block is even useable and base it off it's condition.

[WDRacing]

For the price of new heads, cam, intake and the tune that goes with, I can boost the LS and make more power.

Yes the LS can make 500 in NA form, but with boost it can be done EASILY. Not to mention it can make far more then 500 for the initial investment. I am also a boost junky, NA = slow in my book. Always will, but thats my opinion.

Nitrous is available for ANY TB and ANY intake configuration on the planet. Anyone that says it isn't does NOT know what they're talking about.

A bolt on kit for your LS to make 1000WHP is about 1300, including the progressive controller and ignition stuff.

ok thats cool.

im also thinkin about goin v8 in my other 240. but i was goin to use a 350 sbc. i thought it would be easier to wire up because its carb'd. plus i have a friend that has one i can get for real cheap. and my dad is awesome with chevys.

Even Sport Compact Car?

"The engine has been enhanced with some mild mods, namely Comp Cam bumpsticks (222-degree intake, 221-degree exhaust) and a serious 150-shot of nitrous from the blue bottle folks at NOS. Since the LS1 runs a larger 85mm throttle body, no nitrous kits fit the V8, forcing Maseba to concoct his own custom fogger set-up. BlackTrax's Jei Chang handled the tuning chores, via an EFI Live engine management system."

Not that I'd dispute the great white devil LOL

A buddy of mine has an old school Iron block 350 from a Caprice that he wants to get rid of. I'd go with it and boost and stroke the $hit out of it but I want this car to be a Time Attack/Track Slut.

[cnichols]

Everything WD said is correct. That blurb from Sport Compact should have never made it past the editor. That is pure BS.

The reason I am staying N/A is not because it can make more power or is cheaper (it can't do either). I am a big fan of N/A power due to it's simplicity and reliability. Because 500 N/A hp is enough to put me deep into the 10s, I don't really have a need (with this car) to go the forced induction route.

If I were building a car for the drag strip or trying to make insane power, you better believe a big single would be going on. I would eventually like to make a 9 second naturally aspirated and manual shifted pass with this car and then drive it home. To me, it's more impressive than doing it with forced induction because it'll obviously be more difficult.

[redtop91]

Ok so the only left to decide is how to run turbos and the rear end. What kind of transmission should I use and will it mate up to the R200 with a custom driveshaft?

[WDRacing]

A custom D/S shop will be able to set you up with a D/S that mates up to any transmission and any rear end. You'll just have to take one or two measurements between the flanges. The rear end itself is a great unit. Although you'll be putting a lot of stress on her with a boost LS. Perhaps we'll find the common breaking point?

NOS sells a Nozzle kit that bolts right up to your injectors with fuel rail spacers...very nice tuned port setup. Or...god forbid you use a simple single nozzle setup that sprays IIRC up to 250 or obviously 500 in a dual stg setup.

Nitrous is easier to install then moving a battery to the trunk.

N2O is a good option for you Ryon. The LS in stock trim will be so much faster then your SR it's not even worth comparing. Once the stock LS becomes mundane, $850 gets you a great 250WHP NOS kit. That power alone has you stressing whatever transmission you are going with as well as the rear end. Not to mention undriveable...lol.

Chris, I have often wanted to build a high compression E85 KA24DE just because no one has busted the 200whp mark with a DE yet. But then I realize how much work for such a little payout it would be.

WD

[redtop91]

It's going to be in NA trim for awhile so N02 is an option I'll consider, if only temporarily until the Turbo setup is figured out. LOL I know you don't agree with that but I have a big distrust of nitrous.

[cnichols]

I know of a certain Z33 making over 1000 at the wheels on the stock diff, pulling multiple 1.3 60' times and low 9 second passes...they haven't even changed the fluid yet. No problems. R200 is the LAST thing you should be worried about.

The T56 6 speed will be the most fun and will handle the power.

I'm not a big fan of nitrous myself and would never personally run over 100 shot from a single fogger, but PLENTY of people do it and have great luck with it on LSx engines. Really tough to beat the ease of the setup and low cost. I will be throwing a 100 shot Throttle body fogger kit on mine most likely. Either that or have a dual inlet cold air intake with dual 50 shot single foggers outside the engine bay for cleanliness.

[MrPresidentQ45]

If you've commited to going turbo, check out Squire's Turbo Systems. They make a remote-mount setup that will help with any underhood clearance issues. The've also got some awesome vids of a nearly 600rwhp Camaro. Sounds bitchin, too.On the T-56 front, there's more than one box out there, as far as rated torque goes, so do your homework... A friend blew up 3 of the stock units in an unmodified 2002 SS camaro before switching to a Viper box.

WD

http://www.pdm-racing.com/features/court240.htmlNot 200whp, but they haven't done much either.

If tearing one down and increasing the compression didn't already put me in Street Mod for SoloII, I might consider doing a high comp KA24DE, just for the TQ, but I can drop my CA in there, be in the same class, even out the weight distribution, and make more power with less effort.

That's prob why nobody has bothered trying to do it.
