looking for about 400rwhp .

car as it sits is a 01 z28 a4 current mods are flowmaster cat back Fast toys lid & FTRA and z06 maf .

doing a stall in the next few weeks with 3000-3400 stall..

this is my daily driver and would like to keep is somewhat quiet .

question is it possible to make my 400rwhp with a set of tsp stg 2.5 5.3l heads and one of either the 224r or 228r cams trough stock exhaust manifolds and cats and LS6 manifold & PP tb ??

i do have a set of long tubes and ORY i could install from my other car but would like to hear what everyone thinks .

would like the car to run in the 11s but still be verry streetable . like i said this is my daily driver and wanna keep it verry good mannerd .

any input or opinions would be great .

thanks !

im also looking for these parts used so if anyone has a set let me knw!

not through the stock manifolds. If you are looking for a "quite" exhaust system and hit 400rwhp I would do Long tubes, high flow cats, and a cat-back like magnaflow.

how much do you think it would put to the ground trough the stock headers/cats ?

looking for verry quiet sleeper like car that i drive everyday .

dont knw how lound it would be with the long tubes and ORY

I think Thunder Racings CheaTR packages may interest you.

thanks for the link ill look in the thunder racing cams ..

anyone else ?

what power differnce would the long tubes and ORY really make after the car is tuned ?

really like how quiet it is now ..

and also does the lsa affect power or drivability ? would like the more stock like idle .

Heres what i was running, til a valve dropped:

01 WS.6: Lid, descreened MAF, ported TB, stock LS6 intake, TSP 224R, TSP PRs, Comp 918s, Stock Manifolds/Cats, SLP Y-pipe, Loudmouth 1, Performabuilt 4k stall, and Level 2 60e, 3.73s.

With the converter slipping (and soft valve springs), she made 350RWHP/352RWTQ, so i would think with heads, it could get you pretty close. You could always try port matching the manifolds to the heads too.

Longtubes and even high flow cats make a BIG difference in power, especially with engine mods.

My wife's car has TSP's 231/237 with SLP Long tubes, high flow cats and a magnaflow catback. If it wasnt for the beefy cam, people would probably just assume its stock, or just a catback. I personally love the way it sounds now! Its a complete night and day different between the maggy catback, and the loutmouth that was on it before. Just driving around normally, its got a nice, smooth deep tone to it. When you get on it, it gets kind of loud but not raspy at all.

I made 375 hp (corrected) through an unlocked converter with my TR224 (for sale wink wink) and full exhaust. Over 400 is the number I'd be looking for with heads.

thats what i wanna hear 400rwhp trough the stock exhaust system .

like i said i have a set of long tubes and ory sitting ready to be installed if i have to .but would really like to see if it did it trough the cats .

maybe i should just trow the headers in and stick a bullet or spiral flow muffler inline with the off road y .

is texas speed reading my tread !! make my dream happen ! sleeper with cats and 400rwhp !! lol ..

and does anyone knw of power differnce between the lsa ?

how much you asking for the cam ? how many miles ?

01ssreda4

iTrader: (96)

No I never said stock exhaust. I had LTs and full exhaust.

randomnine7

iTrader: (23)

yeah but you hit the 375 to wheels with cam only .. so in my case do you think heads cam ls6 intake and lid FTRA wouldnt hit 400rwhp ?

I think your goal is with in reach if you are willing to spend some extra money. I think a ported fast 92, electric water pump, and some bad azz heads like afr or trick flows,and lighter valve train and spin it to some high rpm. You know something to make up for not having the long tubes. Or thunder racing cheter cam will make it alot easer

randomnine7

iTrader: (23)

damn if its really going to be that hard to hit the 400rwhp goal with the heads cam pp tb lid then i might as well as just trow the long tubes on .

with that being said how much hp would it make with the long tubes and rest of the mods im planing on doing .

I would throw some carsound cats in that ORY and then run it through a hooker aerochamber or magnaflow catback to keep the sound down. With the tsp 228r and stock exhaust it should be very close to 400rwhp but throw in some LT's and good flowing y-pipe and it should be about 430rwhp.

Last dyno I did, I made 392 with the following; Stage 2.5 5.3 (59cc) heads, 224R-114, BBK LTs, ORY, LS6 Intake, Magnaflow Catback, Vig 3200, FAST Toys CAI, STOCK TB. I had a Fast 78 on it but it wouldnt go to 100 open on the dyno, so there shouldnt be any problem with you making 400 with a good tune and those mods.

man decision decisions ...

anyone else any results ?

anyone have a sound clip of the 224r with the less agressive LSA

Like said above, Put a Maggy on thier, its Great!
Im full Exhaust with a Smallish sized cam, it thumps, but its so refined, I love it!

almost ready to decided

well first off wich cam 224r or 228r ?

hp vs drivability vs idle ??

camz28arro

iTrader: (12)

228r will give another ~5hp over the 224 and still should have good drivability and a smooth idle on 114lsa with a good tune but the tune is a very important part in drivability.

With a 228r you can still run 918 beehives too. I went with a 224 but wish I went bigger.

Both the 224R and 228R are both very driveable, but are good all around cams. I cant speak for the 228R, but my 224R on a 114 hardly had any lope to it, through the stock manifolds/cats, SLP Y and Loudmouth 1. With something like the Magnaflow catback, you probably would hear even less of a lope to keep it nice and stealthy.
