Linn1647545492 Posted April 14, 2010 Report Share Posted April 14, 2010 Guess I won't look for much more than 400rwhp na, sucks the auto takes so much away. If people are making 400rwhp with just a cam and bolt-ons, how much of a gain would be seen with the stg 2.5 5.3l heads or the l92 heads from TSP/PRC? stage 2.5 5.3 heads are a waste. If you are going to get heads spend the money and buy trickflows or ETPs or you can but my ported ls6 heads when I upgrade ported L92s are a good head for the money and with the right combination can make over 500rwhp NA.

V8 Beast Posted April 14, 2010 Report Share Posted April 14, 2010 You don't need an iron block just get a ls3 block. I hate all the new parts that keep coming out because you and I are now both in the same situation we have to rebuy/upgrade aftermarket parts to make more power. The truth is I'm going to keep debating on what block I want until my block gives. And you speak the truth about parts!!! They now have better heads, high flow manifolds, etc etc etc. If I had then what people have now I would have paid less and made 50 more to the wheels.

Flybye Posted April 14, 2010 Report Share Posted April 14, 2010 5.3LM7 $500 give or take MP t70 $500 (or go Holset for less) WG/BOV $200 FMIC/piping/fab work/fuel $1500 Hello 600HP! Quote Link to comment Share on other sites More sharing options...
Linn1647545492 Posted April 14, 2010 Report Share Posted April 14, 2010 Seeing these numbers makes me feel good about the power that my z06 made. Only mods are cam, kooks LTs and magna flow catback and it made 436hp 405 tq. This makes me want to put a good set of heads on it:D What color is the Z?

PM me when you're thinking this might be possible... I daily drove my car with the MS3 for awhile. It might be to much for sum but, I loved it. It won't be until the fall/winter until I upgrade the heads. Here is the thing with your budget 400rwhp is easy. If you want to make another 50 wheel NA plan on spending another $2-3K Quote Link to comment Share on other sites More sharing options...

If you want to make another 50 wheel NA plan on spending another $2-3K Late fall/winter works great with me, gives me time to save up the monies... But fuck spending another $2-$3k for 50whp. I'd rather just leave it as is or drop a G on nitrous and get another 100-150 whenever needed. So are you saying that heads aren't really necessary? I mean I know you can make 400whp w/ out heads, just cam and bolt-ons. So is the trade off cost for power gains not worth it for heads?

Heads are worth it and with a set you should be able to pick up 20-50 wheel. Ported heads will range in price from $1300 to $2600. At this power level you will also need new injectors and a fuel pump. If you have not upgraded your oil pump or timming chain I would make sure it's done at this point. I'm sure you can start to see how the cost of things are starting to add up quickly. Quote Link to comment Share on other sites More sharing options...

I hate all the new parts that keep coming out because you and I are now both in the same situation we have to rebuy/upgrade aftermarket parts to make more power. and this is why i dont mind using used parts from people like you to who just want to get rid of their old stuff that is not bad so to speak but its just time for you to upgrade or move on.. This is the kind of parts I want to base my whole build off of. I am so glad I got a guy at work that can port heads for me cause i am under no time constraint so all i need to do is find a set of stock ls6 heads complete or bare as i will need springs etc anyway Quote Link to comment Share on other sites More sharing options...

Because my heads will out flow any 5.3 heads. Why do you think 5.3 heads are so cheap. Because they don't flow what others do. Quote Link to comment Share on other sites More sharing options...
smokinHawk1647545499 Posted April 14, 2010 Report Share Posted April 14, 2010 the 5.3 dont have good ports compared to the rectangle headed ones. they raised the compression, whichis why a lot of people used them back in the day as they were cheap. the l92 heads flow great stock, those out flow a lot of ported ls6's.

Bam Posted April 14, 2010 Report Share Posted April 14, 2010 ^^^Wait so L92 heads would be good for an ls1 ??? someone on the last page said they wouldn't be...? That they'd be overkill... I obviously need to do more reading on the subject as I just started delving into it, but I don't want to leave this thread confused...

I obviously need to do more reading on the subject as I just started delving into it, but I don't want to leave this thread confused... And this is why I asked people here rather than going off readings from ls1tech... I think best bet for money is to just use some ls6 heads (243 I do recall) and getting them ported.
