Near stock with W/M and Nitrous

[theshark]

Hey whats going on guys. New to the site and fairly new to diesels. Wanted to bounce an idea off of you guys.

I Already have a 550+ hp ls1 car that is a blast and what i race. What I am wanting to build now is a daily driver that can tow the car a few times a year and still be fun.

Seeing that the 1st gens are pretty inexpensive and seem like fun platform i was thinking it my be the ticket. Here was my general Build outline

All the "easy mods" Intake exhaust basic fueling mods. I have a A1000 i can throw on it. Then run a progressive water/meth system and nitrous. Possible depending on the year I get swap to some of the better years injectors and turbo.

This in a 2wd reg cab. Should make "enjoyable" power and not have any egt problems or MPG issues for a daily.

If this was your mod list i would assume a Non/IC would be the best bet right?

Appreciate the help. I am already lurking a lot and checking out the site. Seems like a solid group.

I would get an intercooled model if you can find one. If you want an auto, it's worth the extra gear and intercooler to buy a later model. A good non-lockup converter can still handle over 500 at the wheels.

So, when you gonna intercool yours? We are all waiting.

Is the OD trans as strong and as cheap to build?

What we looking at mpg wise as a difference. Just a ballpark is fine. probably 70/30 city/highway.

i would think 400 is easy to hit right? At under 5000 pounds it should be peppy and fun to play around in. Maybe walk a few mustangs and newer trucks.

400HP is going to take some work.. I wouldnt say it will be easy but it can be done.

[Richie O]

300 is easy, 400 is not.

400 hp , is what , 1500 -2000 dollars worth of engine mods ?

[fatty]

The injectors and turbo for 400 hp will cost that much or more. And then you need studs, springs, injection pump parts, lift pump etc..

Transmission work and torque converter..

i was just thinking engine mods ..... ie new injectors , a turbo and bigger lift pump / larger fuel lines and some sort of intercooler and bhaf .



injection pump parts are little more than some sort of govenor spring , grinding the fuel pin and possibly making changes to the dynamic timing in the pump .


the rest of the stuff are things that break from 400 hp

[dunes450r]

you'll definitely want an intercooled model. and i would surely go for the 518. O/D will add close to 2-4 MPGs on the highway, and you can cruise at 65-70 easy. someone's brother on here put like 700hp through a built 518 without it breaking(p-pump)

If you're willing to run w/m and nitrous, I would think 400-500 should be easy to hit. I hit 448 with a converter (727 trans) injectors (6x16) a 60mm turbo upgrade, and a .125 jet. W/M shoulda coulda woulda bumped up that number another 50hp or so. 20 city 30hwy will be a lot harder unless you're willing to drive 50mph on the highway. More like 17/23 I'd say.

[Remps]

The 727 is nice for city driving. If you plan on long highway trips tho, don't get a straight pipe with a stack, your eardrums will hate you.

[theshark]

You guys think it will take that many mods with w/m and spray?

What will the stock 518 hold if its in decent shape with a good converter? What would consider safe? If there is such a thing.

Like I said earlier. I have my race car. i just dig 1st gens and they seem like a fun daily.

On the mileage I was stating I drive a mix of 70/30 city/highway.

If i could get 17 babying it in town with the w/m i would be ecstatic. Again something nice reliable and enjoyable when im not in the car.
