SS_Detroit

looking for input on my first turbo build.

Engine is a Lq4 with a stock bottom end (at first until forge everything). I will most likely use the stock heads and cam. I really like the LSXR 102mm intake (honestly i like the looks of it. haha). Im thinking pt-88? this is where I'm lost....

engine will be mostly a friday/saturday night WOODWARD car. ill see the track a few times but not too much. i don't beat on my cars too much but i do get on it from time to time, more about bragging rights among friends. Im 21 so most of the kids my age are running tuners and i need to be able to beat em all. Friend has a 600hp sbc tho running 11's and i need to beat that too...

Engine is going into a 86 monte carlo SS and going to be swapped into a grand national down the road hopefully.

I don't want to call it budget because mommy and daddy aren't funding this, i work for everything i have (car included).

Goal= 750 rwhp pump gas

Now, My questions are...
what kind of power can i expect?
is a pt-88 too big? will i have to much lag for a street car?
will i spool fast enough off the line?
what should i do to get to my 750 on the LQ4...?

BTW this is my first post! so, new to this whole thing...

What year is the LQ4 and what transmission are you planning to use?

SS_Detroit

its a 2005 Lq4. the trans is going to be a built 200r4.

Sounds okay.

1. Leave the Truck Intake. They flow well, and you will be forcing air into in anyway. Take the money that you would use on the intake and get a nice cam, valve springs, ARP Headstuds, and LS9 Headgaskets.
2. You have the Gen IV LQ4, they have the better rods (if it later).
3. 700rwhp is attainable.
4. PT88 is not too big. Its actually a perfect size for your goals.
5. You can. Most likely you will need a Trans-brake, 2-Step, and good Boost Controller.
6. To get to 750, booooosst!!!

What kind of fuel will you be using?

A budget build doesnt mean "Mommy and Daddy" is paying for it... as for me im on a budget because Im a broke *** college student that pays bills and buys parts when I can... "Mommy and Daddy" have nothing to do with it.

As for you questions...
The 200r4 better be built good! 750hp is a lot of power to throw at it.
Pt-88 i feel is a very big turbo for stock cam/heads and will spool slow.
I feel 750 will also be hard with a stock cam.
In order to make 750 or even come close water/meth injection is going to be a must because you will need close to 12-15lbs of boost and a great tune.
Bigger injectors are also a must 60-80lbs. you can only make as much power that your fuel system can supply.

Ls6 cam put me there? and what lave springs would you say...

SS_Detroit

@redmilleniumz28 guess i didn't phrase that right. I meant to say i don't want to call it a budget build, but i don't have the parents throwing dollars in it either so I'm kinda on a budget but I'm not going to short myself on quality parts...

lol ya i took it the way you didnt intend it lol...

Ls6 cam is good 02+ i think it is but may be hard to find, and new, can be pricey, when you can get a custom grind or something for $389. as for springs i just ordered Patriot xtreme dual springs paid $275ish and they have like 140lbs seat pressure.

A FAST wont be required to hit your goals. Depending on what heads you're running, go with a car intake and spend the leftover money on a boost specific cam. And don't worry about whp too much. Any tuner can make the dyno read pretty happy. Take it to the track and see what your trap/et is and brag about that. Much cooler

The PT88 would work but it's a bit big for 750HP. Why have the lag of a 1000 HP turbo for 750? A BW S475/83/1.10 would be about half the cost, and spool quicker. A PT76/75 would also work well. I'd also put in a small cam with Isky or pac springs. I run same 2005 lq4 in my truck with Custom Isky 212/112 turbo cam, and GT76 turbo. Times and weight are in sig...

agreed 88 is too big.. lagggg ,,, pt 76/75 would be nice..but exspensive.. , ls9 gaskets, arp head bolts or studs... bigger cam , biggg fuel system..save your money dont buy a aftermarket intake..
budget build has nothing to do with parents.....
$3600 into my whole swap ..with turbo, fuel, trans, everything.. 6xxrwhp.. 5.3

A PT88 is a T4 Based 88 guys.. It actually has a rather small Turbine size.

Rather small? It's still 94mm? Bigger than anything else t4 based. A lot bigger than the t76 and pt and bw stuff most are use to.

TheLS1Lover

The PT88 is not a 94mm Turbine size. Its an 87mm I believe. Its T4 based so that doesn't help either. Precision rates it at 1250hp (I know underrated), and by looking at the map its just perfect for a 364-370. Anything bigger is no good.

It will spool slower than a t76 when a 76 will do everythink he needs to do pt88 will take a lot longer to spool and do the same for power on that engine

TheLS1Lover

The thing with the 76 is he won't have that much room to grow.. Maybe a 100 more hp but not much. A PT88 will make more power at the same boost and tune. It will flow more air at the same boost.

Your believing wrong. Look into it. I'll pull out the calipers and get you measurements on a gt47 which is a mm smaller than a pt88

TheLS1Lover

That measurement came directly from here (LS1Tech) via a search, via Forced Inductions. Actually it seems there are more than one. If its a 87, 94, hell even a 110, its still a T4 that will spool good on a motor this size.
