Hello everyone.. been a bit since I was last on here, mainly due to work and family.. but im back none the less.. anyways I put together a new motor!! well its 90% done.. but figured id tell you guys about it and see what you all think?

motor is a good ole ls1 from a 2002 camaro, fully rebuilt and forged! I will list specs below on what was used. This motor is 9.5:1 compression and I orginally was going to use it for boost.. but things come up and I got a deal ona nitrous kit and figured im just going to spray and have fun.. I mean when I launch on the car hard anyways I will be at the strip and only be for 10-12 seconds anyways.. I dont need the power 24-7 as much as I drive this car.. not to mention it will be fast anyways..

car is a 94 mazda rx7-
-8.8" ford IRS swap performed with 3.55 gears and a carbon LSD
-stage 4 built 4l60e trans and a 3600-4000rpm stall depending on cam of course.
-ls1 is standard size 347, forged diamond 9.5:1 pistons with file fit steel rings
-eagle h beam rods with arp 2000 bolts
- stock crank but polished and balanced like new
-ported ls6 oil pump and new pickup
-arp head studs, and main studs
-patriot stage 3 5.3L heads
-crane gold 1.7 roller rockers and chomoly pushrods
-stock ls6 intake and ported throttle body
-full hinson headers dual 3 to single 3.5" exhaust system stainless steel
-255 bosch fuel pump with 8an lines to fpr, and i currently have #60 injectors but will prob go smaller now since I have no boost to run.. may drop to 42's?? not sure..

cometic head gaskets and blocked machined to use them.

motor is nicely built.. its not the worlds strongest but its def not a weak motor. It should hold what I am looking for without issues..

I am debaing on a camshaft to run, and also about if this would be a good combination for nitrous.. really thinking a 200hp shot is possible safely given a tune and fuel. Id like to keep around 93 octane for everything strip and street.

whats everyones views on this setup? any guess if it will hold what i am seeking? any idea what this setup can produce off the bottle? I am hoping I can break 430whp naturally before adding the bottle.. anyone see anything I may want to look into before moving forward.. just general help guys!!! help a brother out!

 

All that and no details on the system?

I don't think it will do 430rwhp NA. Low compression, ls6 intake, pretty taxing drivetrain losses will add up quick. Just a guess tho I hope the best tho.

Also that combination will easily do 200hp with the right tuning. All day.

Did you have any other specific questions? Happy to help out with the setup if you need it.

 

whoops sorry man. I guess I did forget to give the specs on the nitrous system here it is..

Nitrous express kit 20109-00 and I have a 10 pound bottle for it. supposed to support 250 shots, which a 200 is all I really need.. My car weighs 2800 with me sitting in it.. the car would be fast with just 400whp as is.. least fast enough for me.. Just when I go to the strip id like an extra gitup and go.. thats where the Nitrous system comes perfect at!

basically if i can break 400whp on the motor alone, and add some juice to it on top i would be happy.. Maybe one day I will upgrade intake to a fast or such but right now its not really my main goal as it will run fine as is. compression im wanting to keep cause I spent all the money to build it, and if i lose 20hp im really not going to complain that much.. I mean I have a stout motor i doubt I will have issues with.. reliability here is more importiant to me than a few extra ponys

- im really wanting to make this the safest setup I can get out of it. I already purchased a fuel pressure gauge, and a nitrous pressure gauge to monitor that. also I have a wideband o2 sensor already setup on my car I will use along with this setup..

just wondering about cam choices to look for, also a good controller for the system unless a normal pedel switch will do fine for my goals.. Kinda concered about when I go to the strip just lighting up the tires at launch and basically hurting my time rather than helping it.. so I thought about a nitrous controller but dont know much about them..

I also will most likely get a window switch that will kick it on from say 3k to 6800, right before I shift. but it depends on cam choice too..

 

If you are wanting to go that high I would look into getting rid of the nozzle. Distribution can be killer on larger shots with a nozzle if you are not reading every plug. I have a feeling that pulling out all 8 plugs is not fun in that car.

I can certianly get you lined out on a controller. Just so you know any progressive controller we sell will have TPS ( No need for pedal switch ), A window switch ( No Need for a separate unit ) And then of course the progressive.

 

heck I didnt know that.. so i just get a controller and it does it all

I wanted a fogger system for each injector but for my lack of full racing goals I dont see the need to really dump the extra cash for a few extra horsies.. in fact a 175hp shot is fine.. lol im not really set on a number.. just fun.. 200hp was just a random point id like.. and the kit claims 250 cappable so i figured drop it some and bam there is my goal

 

Yep. The progressive will have you all fixed up.

Direct ports and plates are not really done for added power. They are done for distribution and individual cylinder tuning ( On Direct Ports )

Its not that the nozzle will not handle the power, its that it will not get it into each cylinder evenly. So think of it this way.

200hp should put 25hp into each cylinder. If you have say closer to 30hp-35hp going into a cylinder, well that means you a have a cylinder seeing closer to a 250hp+ shot. So not only is it more nitrous, but you have the car tuned for 200hp. This is the biggest reason we push the plates.

Its not that it can not be done with a nozzle, it is just simply not the best option and takes more tuning and plug reading.

 

Or he could find a few more nozzles and put one on each cylinder :p

 

graham could you link me to a kit like you mention. i understand what you are satying completely I just want to visually see what your refering too to understand fully.

This should help with some visuals.

 

yep exactly what i was thinking it was.. Just wanted to make sure.. Thanks for being A++ on the support man, its appreciated.

If I go with a plate system which it seems like I should cause its a minimal cost for security and tuning. which type of controller would you think would suffice for someone like me and the goals I am shooting for..?

 

Not a problem. Pretty easy to post up a little info.

On controllers, its pretty clear cut IMO

Laptop tuning, more adjustable, dual stage - NOS Mini, FJO Mini

Handheld tuning, simpler, not as adjustable, single stage, slightly cheaper - Nitrous outlet Progressive.

We carry all three. Between them I feel we have the perfect controller for 98% of LSX users. If you want to give me a shout and really go over your plans on using it and things like that I'm happy to go more in depth.

 

id prob want something pretty simple. I oonly plan to realy use the bottle at the strip and that wont be often.. maybe 2-3 passes a month just with friends.. on the street maybe ona highway run here and there but thats going to be rare.. Im a fairly safe driver.. Id rather not take the chance on killing some kid or killing my pride and joy over a few seconds of speed

I just want to make sure my setup is fairly safe, and tuned pretty good so it makes some good power.

 

Our controller will fit the bill then.

When you get the motor lined out, I can help go over all the tuning aspects and make sure the tune up is safe. Things we can go over to make sure you will not hurt parts. Fuel pressure, octane, timing, which plugs, etc.

Just let me know. A Simple plate/nozzle setup and a progressive with a few safety items added is a pretty safe setup especially with a forged motor. Pretty much fill up the bottle and spray it away once we get it lined out.

 

sounds like a plan to me! soon ill have a 600whp monster on the bottle haha
