im runnin a stock ls just got it and all of the internals are stock, im planning to get speed fast but im trying to stay away from lsvtec. what should i do? some internal work and then throw a turbo on? or what? if i do decide to stick a turbo on it i need to know how much lbs of boost an ls motor can handle help please

 

Depending on how much you want to spend. You could go all out and sleeve it and get rods, pistons,turbo...and run 30psi or leave the bottom end stock and run 7-8 psi safely.

 

You should get a hold of Iggy and all those DFW guys...you have no idea how many LS-T's are running around there. Most of them are running stock motors and making anywhere from 250-320HP.

 

OK. I'm on the same route you are on. I have a 95 ls. IMO i think going turbo is way better hp/cost wise. you need about 3000 for a kit or you can learn a lot like I a doing and build a kit yourself. It's going to cost me about $2500 with tuning. First, what kind of HP are you looking for in the end. With stock internals you can run around 7-9 psi but no more then 10 (even that is a little risky). You will get about 230WHP with that setup. If you want to go higher like break the 300WHP mark then you have to redo internals like pistons, sleevs, and rods (not to mention other things). After that though it's gonna cost a lot of $$$ to go higher in HP. My only question to everyone else reading this is what Turbo is best for street racing and getting like 230WHP. T3 60 trim or a T3/T4. If so what type of T3/t4? Good luck with your project either way you go.

Incorrect. The stock LS sleeves should hold well over 300hp. Boost pressure is irrelevant.

Im hoping to hit around 300-310hp out of my stock motor...i should be running around 15psi.

 

OK you might be right about the sleeves but definatly not the rods. I'll give you 50 bucks on your way to a new engine if your car lasts one month on 15psi. You'll snap one sending a piston right through the block.

 

I'll take that bet ANY day of the week.

Do the research...its been done.

your right theres a few members running 1 bar or more on a STOCK b18b... and have them still running since i dunno even when. its all in how well the car gets tuned and what not.

 

if u buy a bolt on turbo kit i.e. GReddy, drag, revhard.. are u set with everything? as in fuel management? i dont plan on putting big numbers. i want to keep my motor as stock as possible..as in not having to replace internals.

 

First off..if you are set on buying a pref-fab kit, i would recommend Rev Hard over all the others.

Now..to answer your question, we need to know how much power you plan on making?

 

i got a Revhard manifold for sale, 2 months old and powder coated. asking 350.00 located in DFW, TX

 

go to the FI forum
get a turbo setup / uberdata
make 270whp
????
profit

 

LS Turbo

 

Yes, Like one person already said you can either keep it stock with a bolt on turbo kit which I would say (Drag) and run 7-8psi safe. Our, you can go all out with it and invest alot of time and money and boost 20 or 30psi.

 

If your gonna slap the turbo on a stock motor, do a compression & leakdown test first, you also may want to consider a properly installed block guard and some arp head bolts.

Since you're being generous with your money...care to offer that bet all around?

I would but now I'm scared. I really thought that with STOCK INTERNALS pushing above 10 PSI was dangerous and 15 PSI is just insane. I understand that tuning is a big factor and that a hondata unit or some standalone is required, but 15 PSI is a lot! Please inform me and anyone else how to achieve this on STOCK INTERNALS. I'm extremely interested!

 

First of all...dont make the amount of boost your goal. Horsepower should be your goal. For instance, im hoping to make around 300-310hp. Depeneding on the size of the turbo and the type of tune i get, i could hit this number at 13psi, 15psi or even 20psi. That doesnt matter at all...its the amount of horsepower that matters.

Heres me paypal quikb18b@aol.com

On a serious note Ive been running 1 bar on my completely stock Ls for 5 months now, no problems, It doesnt burn any oil, and it runs like a champ. I take care of this car/motor, but it gets more than enough boost

Your right 10 psi on a bandaid fuel setup is bad, but like you said tuning is everything. On a stock Ls, if your running Fmu, I would run more than 7-8 psi, 9 psi max, at that point youll be mazing the stock injectors, creating alot of fuel pressure ect...

Bring a good standalone into the picture and amazing things can be done. And yes like mentioned when reffering to limits of a motor look at power not psi. The Ls has been prven to handle 300 hp and be failry reliable. Like I said yes im running 14.5 psi but it's on a very conservative tune. The air fuel is 11.8, and the we took out alot of timing. Theres more power left in my tune, but I wanted to be reliable first and make power second.

Yes im running more boost than usual, but we had to do this because it was tuned safely.... meaning it took more boost to make x amount of power.

And remember boost pressure also isn't the greatest tool in determining limits because of different sized turbo's.

 

turbo question...im got shotdown on the supercharger idea, and now im in turbo mode...i found a garret/turbonetics T3-60 has a exhaust turbine A/R of .48 and a compressor trim of 60. Compressor housing has a 3.00" inlet and 2.00" outlet. would this be good or should i go for a T3/T4.... searching doesnt really help me much im just looking for some answers..not facts...anyhelp would be great, dont flame me im a n00b at this.....its a whole kit but im just making shure that the T3 60 trim will be ok....is it better than the t3/t4....man im stupid!

i plan on not making much...whats the average revhard turbo kit whp? ..when i slap it on.. i'll be keeping the turbo kit at the psi it was set.

You know i asked the exact same question at team-integra.net. Either of these turbos make good power. The T3 spools a little faster and peaks almost at the end. The T3/T4 spools up a little slower but pulls hard to the end. http://www.team-integra.net/fo.... T3/T4 though is a lot more expensive though. I think I am going to go T3/T4 with the recommendations that the guy told me in the link. Also check out how to calculate compressor maps. This can help you find a good turbo for what you want.

Probably somewhere between 190-210

Well in that case everyone should boost 30lbs on their LS's...

As long as they arent producing more horsepower than the motor can handle, then that would be perfectly fine.
