Ok this is what I have..
02 ls1 6 speed

TEA 1.5 5.3 heads.
comp cam 224 224 581 581 112
FLP's no cats
FIPK intake
MTI custom tune

The can made 400hp and about 395tq after tuning
with mac mid lenghts no cats
Just put the FLP's on.
And Iam going to get a ported TB and ASP underdrive pulley
Iam hopeing that with the FLP's and underdrive pulley and Ported TB
I will at least be at 425hp after I get it tuned again..

I want some more HP and TQ..

Schould I look into geting a 383 would that bring my HP and TQ up at least 40 to 50

If so what 383 kit schould I go with.. And will a 383 kit work fine with my heads and my cam..
Any prices??
Or would a 75 shot be the way to go.. I no that it would be alot cheeper.. But I just dont no what to go with..
I dont no if it safe to spray a 75 with the heads and cam I have.. Because my compression is like alot higher then stock right..

What schould I do??
thank You
Frank

 

Bauer Racing has an engine designed to make 550 rwhp and 900 with the n20 on it. I sold most of the stuff, but the pistons are still available. Brett can hook you up with some power.

 

how about 388 all bore AND N2O!!!

 

What schould I do though..?
383 or like a 75 shot
How much would a 383 cost ?
And would it work fine with my heads and my cam?

 

the heads would be small for an all bore motor......might work ok with a stroker 383 but the cam will be small....

if you are building either a 388 all bore (forged rods and pistons) or a 383 stroker (forged crank, rods, and pistons), then you could put A LOT of N2O on it......

 

a lot cheaper to go with nitrous.. 100-150 hp with about the same in torque at the push of a button.

 

How much would a 383 stroker with forged rods and pistons and crank cost.. And would it work with what I have now.. ? And would it give me somemore HP and TQ..?
Would it be the smartest thing for me to do next? To gain more HP and TQ or what? schould I do..
How much would the 388 cost? and would it work with my heads and cam?

 

at least 2 grand in parts for a Lunati kit Then you have to figure gaskets and labor unless you're gonna do it all yourself.. You'd have to rework your heads to work with the 388. It would definitely give you more low end torque and make daily driving more fun.

The purpose of a stroker is for more torque not really for horsepower. You'll probably stay at the same hp level but with a lot more area under the curve.

Either combo would work with your heads/cam

The 388 all bore gives you the advantage for higher hp, higher revving.

 

the 388 bores are quite a bit more that the 383 strokers are......

 

I cant afford to rework my heads..Or do I have to have them reworked to have a 383 as well What can I do to make more HP and TQ.. Would a 383 kit work fine with out rework my heads??? And could I get that hole get for 2,000.00 .. Would that be the best for all motor.. power..
Or to safe time and $$$ could I just spray like a 75 shot.?
what schould I do??

 

N2O is your best bang for $$$.........

for a 383 stroker short block, look at least $3K before its all in (thats if you reuse your heads AS IS).....

for a 388 bore short block, look at least $4.5-$5K...possibly more before its in (again....heads AS IS)....

 

So Nos I Guess Is The Way To Go For The $$$$ But I Mean.. Is It Safe To Spray.. Since I Have High Compression?

 

How Much Would It Cost To Get A Kit That Has Everything Forged For My Car Now That Way I Dont Have To Worry About Breaking Anything On Gas?

 

10.7:1 isn't high at all (for N/A and N2O).....spray away.......

just make sure that you tune it (don't go lean) and make sure you don't have too much advance

 

Do They Sell All Forged Internals For My Stock Block.? How Much? And That Will Help With Keeping Thing From Breaking Right??

 

Yes they do.....but you will probably need to have the block bored/honed....

- forged pistons are ~$600-$700
- forged rods range from ~$400-$1200 depending on what you get
- forged cranks are ~$850-$2000 depending on what you get

then there will be bolts, gaskets, rings, bearing, etc.....to do just a basic bottom end rebuild (keep stock crank/rods and install forged pistons), I was looking at a minimum of $2000 and that is me pulling the motor from the car, disassembling it, reassembling it after all the machine work is done, and installing it back in the car......

There are LOTS and LOTS of people who spray 100-150 shots on completely stock bottom ends all day long. If you tune it correctly, you won't have any problems with what you have now. If you really want some insurance, install a set of ARP bolts in the rods (this can be done with the motor in the car).

 

thanks for the help I dont have the $$$ for a big motor right now..
I think that Iam going to just spray a 75 shot..
thanks for the help

 

get it tuned and you will be able to spray that 75 shot for a LONG LONG time.......

 

Go with Nitrous. It takes a lot more than just a crank, rods and pistons to build a 383 Stroker properly. Like a ported oil pump, double roller timing chain, heads re-worked, bigger cam, proper exhaust, tuning, machine work and labor. This add a couple more thousand very quickly...

You could even bump up to a 100 shot and be fine.

 

thanks for the help.. Now I just have to find what NOS kit to go with..
