So I have decided to start a Turbo Lt1 build but not sure how to go about it I guess you could say. Just want some input from guys who have already done a similar build. Looking to make close or alittle more than 800RWHP. Any input is much appreciated. Thanks

 

1000~ flywheel HP won't be cheap at all, you need top notch parts, probably well over 20K to build an engine and drivetrain to handle that sort of power. Expect to never see the most of that money again once invested. If that does not scare you off, I'm sure others will chime in with ideas from their turbo builds.

What are your goals for the car besides 800+RWHP?

 

I run a front mount 76mm with a 383 stroker that has a 24x ignition. It's not cheap to do right, my cooling system has easily $1,500 in it alone.

Who is building the hot side?

 

No body has started building anything yet. This is more of a preliminary forum to see how some people did there cars. And from what I've heard so far this could get just a little to pricey for me. What are some more cost effective ways to build a good turbo motor that makes good power?

 

I have about 5k in my motor, bought used parts etc, and I have a realquick turbo kit which is again, also around 5k with turbo.

Then, trans, DS, and rear end...

Oh, and fuel system for 1000hp? Open wallet and have at it. The fine line IMO is how far you can carry 80# sticks to, cause once you pass their capability you jump into the $1000 for a set of sticks club.

800whp will also require a nice turbo, so either sacrifice the room and get a S480 T6 or spend the coin and get a mid frame, PT88 T4 etc..

Easily 30-40k, for what?

 

Building a fast car in general is a lot of money, whether N/A, Boost, or Nitrous. Doing it right it costs more, but so can half assing it and having to redo it so if your're going to build something with that much HP, don't skimp on cheap parts. For example, a buddy of mine took a bone stock '01 Z28 and did a H/C LQ4, FLT 4L60E, 12 bolt, and full suspension. Just for that N/A build he is well into $18K that he'll never get back. And that was a used trans, used 12 bolt, and some other used odds n ends, the motor is all new. But that's part of this hobby and honestly doesn't bother me because I enjoy going fast. My car i'm clear into $12K or more and it's only a cam only 12 sec car.... But I bought all my suspension, built T-56, S60, motor parts, all brand new. I'll be close to $18K+ once my new motor is done. It won't be hard to surpass $20-25K on a turbo build.

 

You need to lower your HP expectations if budget is an issue at all; aiming for 600+ RWHP is much more reasonable. As mentioned you can save money on some used parts, a rear mount turbo kit setup is also cheaper since you don't need all the hot side plumbing and moving the radiator around but has other drawbacks to deal with. You just need to search see what is out there and figure out how much you are willing to invest.

 

I would have like to add a turbo to my build.

this is a lsx but it has alot of pictures on the piping.

First, get a plan.What are you going to use the car for??Daily driver, weekend toy, etc...Second shop around, take your time, it'll be worth it, only you know what your goals are(with the car) and at the same time save some $$. I skipped lunch, or brought a sandwich before, many times.Lastly PLEASE stay away from E bay. They have substandard parts, most VERY cheaply made in China, or Mexico.*** DISCLAIMER-- I'm not an expert, or a know it all, this, and a little bit of experience have worked for me. $0.02

 

Supporting mods are whats going to kill you. The engine you could probably get away with for ~12-15k if you can do most of the work yourself and browse forums for quality used parts.

Fuel system, trans, and drivetrain will easily be another 10k though. Then you still need a suspension to put all that power to the ground and a dyno tune (which you'll probably be looking at a 24x setup which is conservatively another $1500).

Cost goes up exponentially with power. Using rough numbers as just an example, you could do a 600rwhp build for half the cost of an 800rwhp build. Do you really need that extra 200hp if its not a grudge or track car that is making you money?

Heck, if you just want to be boosted for the sake of being boosted you could get a basic forged 355 done for cheap from a reputable shop, slap a used procharger on it for ~2500, all supporting mods, then make 500rwhp all day and have one hell of a street car for less then just the motor+turbo of an 800hp setup would have cost you.

 

First off whats the most horsepower you have ever driven in? and how did you come up with 800 RWHP?. I have heard so many people that say I want 1000 RWHP and have no clue, then ride in a 400 HP car and say thats "Scary Fast"
I think with heads, cam, gears and maybe a 100 shot will be more than enough for you..

 

Yea, I would ditch the HP dream and decide on an ET/trap you want.

I can toss my car on a dynojet and make all the numbers I want but it won't reflect that on the strip...

 

^^^ All of this.

 

^ This too.

 

I appreciate all the input from everyone who has replied to my post. I know for sure I want to do a front mount I have found 2 places that offer kits with everything even the spal fans except the turbo and cold side piping for a decent price. I have a friend of mine who can custom make cold side piping for me. Also another friend of mine owns a shop and can get a decent price on a turbo for me as well. I think with all the information that has been given to me now I'm looking to run 9.5-9.8 in the 1/4 I've had a cam and nitrous car already but have always wanted to do a turbo car. Does anyone on here have a car that is turbo running that time or close?

 

My car has the steam to, but we shall see if the suspension allows it.

Who offers LT1 specific turbo kits?

Out of the three I would hesitantly send one my money but that is slim at best.

Again, whats the fastest you have ever run in the 1/4? All said and done, to run 9's you will need ALL supporting mods, besides the motor that can handle boost, the fuel system, the Transmission, Rear end, the suspension ect.
Plan on $20,000 +, if you have that kind on money laying around, then go for it.

 

I wouldnt say you have to have $20k to do a turbo LT1. Im thinking $15k or less. Depends on your rearend you choose. My motor was about $6k alone, hotside was custom at about $1k and turbo $1300. But I wheeled and dealed on a lot of parts. You can save a lot of money by doing things yourself if your competent enough.
