OK,, French... Heres my 2 cents:

- YES,, the FAST 102 will fit and flow very nice.

- Engine: A late model C5 has better lower end than early c5s The rod bolts are a little stronger (nothing to write home about)

Things that you MUST replace for reliability PERIOD!
- Harmonic Damper with aftermarket
- Clutch (EVERYTHING) with Mantic from ECS (East Cost Supercharging)
- Torque Tube rubber couplers with couplers better than stock Best upgrade to 2001+ Torque tube
- Fuel Injectors 60/lb/hr or bigger
- Better rockers , Trunion Upgrade or new better roller tip rockers
- Better heads= LS6 minimum or Ported / Aftermarket
- 2004 PCV System and a catch can
- Meth Injection System
- Aftermarket fuel system
- Much Better/bigger Radiator
- PFADT Parts= Differential mount, engine mounts
http://www.pfadtracing.com/catalog/index.php/cPath/26

- Cam/Lifters, Lifter Buckets, new lifter pedestals, HD pushrods Dont Skimp on this stuff
- Best Timing Chain you can get = "KATECH" http://www.thunderracing.com/shop-by...Chain_349.html
- High Volume oil pump = MELLING
- Differential parts= ECS Differential/Transmission Brace
- EFI Live or HP Tuners PCM Tuning suite
I use EFI Live cause I have friends local who use that same setup and help me tune!

Thank You Bill Curlee!, I agree on all that stuff and plan to do most of that.
Still researching the different components and deciding what brands to run.

as for the tuners:
EFI Live is $6k on there website. That is not going to happen.
HP Tuner is only $500.

I don't understand the licenses... I just need it for this car I guess.

I want to learn more about that tuner. I want a tuner, intake and throttle body first.
Seems the best place to start. Then exhaust, then cooling, then fuel system, then injectors and turbo (low boost), then engine internals and so on.

For some reason everyone jumped ahead. My goal is not to buy parts twice.
I don't want a tuner now that wont work with the turbos.
I dont want an intake that wont fit under the hood.

I have built many engines. I will not just boost the holly hell out of a stock engine.

 

You don't need to use much boost to get nearly 700. I've got 620 with an out of the box A&A centri, and stock shortblock. 'Course, I already did the H/C/FAST thing, so it's not exactly a stock motor. I do all my own work, except for the tuning, so I can't advise; other than don't bother with a hand-held. If you're talking about the Holley intake; it won't fit, and not worth the time, if you're planning on TTs.

 

I sell HP Tuners so I can help a bit...

You want the pro version so you can run a wideband. That would be necessary with the mods you have planned in my opinion. We offer combos with a pro system and wideband. $649 for pro by itself.

As for the licenses you won't need to buy any extra. It comes with 8. Your C5 will use 2 credits.

Feel free to pm me if you have additional questions.

 

Now add up all the parts above THEN the twin turbo system and see what number you get.

 

JW@JWMotoring.com
I will run a wideband, I have one on both my L98's

I will save receipts and post in a couple years.
I have all the receipt for my Camaro.
I am 100% sure I can get to 750hp under $20k
You are thinking shop prices or something.
I might be able to do it for $10k.

Can you get an L98 to 500 hp under $3k I can and have done it twice.

750hp on a dyno is not the same as going around a road course at 200 miles per hour.
I don't need a lot of that stuff to go in a straight line.

 

And let me guess you don't have $20k in that car.
please explain H/C I get the FAST part.

I have tuned a few fuel injection set ups.
I prefer to get them running then take them to a dyno.
But I do fine tune them while at the track.

 

EFI Live V2 personal version with two licenses is around $850

What you saw was the professional unlimited lessens version/// Only tuners purchase them..


Here is the two license version

http://www.efilive.com/index.php?pag...mart&Itemid=54

 

H/C = heads and cam. In my case, I had custom Trickflow heads, and a Crane cam. Still use the heads, but changed the cam to lower the DCR to under 8:1. My static CR is still too high@ 10.9:1, but I drive it rarely, and don't race. Oh, yeah, 20k....LOL that number came and went years ago, but over 10 years, and some redos....things add up.

 

Zeevette do you like the trickflow over AFR's?

I saw more hp out of the AFR's but they were 53cc and the trickflows were 63cc.
Mine are on L98's. Will do heads on the LS after I learn what heads are best.

 

Like lol

 

not at 5k feet.

 

I went down the same road you did. Ended up buying a used built engine/turbo/clutch set-up from another member and swapped him my stock parts. Ended up being VERY cheap for what it is.

So, first I would trawl the for sale section and look for used turbo kits. That's by far the cheapest way to find them, and if you can find a built engine that's even better.

Look into getting an LQ9 engine. They're basically the iron version of the LSx that goes into trucks. They're cheap (you can find them at junkyards), and the iron block handles boost well. Most LS1 parts bolt on to an LQ9, but do your research.

For now, you want to hold off on any part that will be dependent on the turbos. I wouldn't mess with headers or cam, because most turbo kits can't use longtubes, and you'll want a different cam when you go F/I, so kind of useless to buy one until you do so.

Fast intake is a good choice, and a good catback exhaust and larger throttlebody are good investments now.

When you get above 600hp you'll need a better clutch (lots of choices), and you'll want to either replace the diff with a built one(expect to pay $2K for a built diff), or you can buy a trans/diff brace which stiffens them up, and helps hold power. I don't know how long they hold up to 700+hp, but at that level you'll surely crack the stock diff the first time you launch it if you don't buy a brace...

The Z06 diff is also a little stronger than a stock c5 diff, and they're not as expensive as a built one. I have a Z06 diff and ECS brace on my drivetrain. I don't know if it will hold up to dropping the clutch with drag slicks, but that combination will hold up 700hp pretty well without breaking the bank.

You'll also need to upgrade the fuel system. You'll want to add a return fuel line and put a boost referenced fuel pressure regulator at the fuel rail, along with either a big or double fuel pumps.

Also don't forget that you'll need better tires.... And new wheels since the stock c5 wheels are only 9.5 inches wide in the back. 10.5 or 11 inch wide rear wheels and ~305mm tires are going to be needed to have any hope of traction....

Welcome to the addiction, at least you have a pretty realistic budget! haha

 

PhysicsDude55
Thank you...

I know all the other stuff will be needed some where down the rod. I agree on the headers.
I have borla cat back. I have foose wheels that will hold a 305.

I have not even begun to look at rear diffs. I am a long ways away from that.

I think I have an LQ9 in my 99.5 2500 Hd. It is the 6.0 LS1....
hmm.... wonder if I could switch blocks.... That will be a later thread.
After I read about what I have learned today.

I plan to buy whatever I can used. but... the parts list has to come first.
When I started this thread I was doing homework for that parts list.

I built my Camaro dirt cheep cause I waited till I found the parts.

Will look into the trans/diff brace
I will do fuel system when I do the turbos unless it seems needed sooner.
1 step at a time.

 

Do all you can to the car befor the tune, Why waste money on so many retune,s. Plus that 102 mm tb is a waste of money also.
You can put intake ls6 or a fast 92 or 90 on it,plus headers cold air intake, also plus a good cat back all befor a tune on the car. But a cam or more you will need a good tuner to max out the rwhp for sure here. Robert

 

I can run the 92/92 Fast and not re tune... sweet.
I will happily get those first. I figured I needed the tuner with any intake change.

 

French

ANYTIME you change engine parts between the MAF and the CATs,,, it requires a TUNE to run effectively and efficiency.

With that said,,, I will say that,, the engine will run and gain some power BUT,, You will leave a some power, driveability and engine efficiency on the table.

Things that you usually cant change without a tune are HEADS, INJECTORS and CAMS and ANY power adders!!

With other minor bolt on changes it will run RICH (which is safe) but again,, not efficient.

Good advice on adding ALL the parts that you can at one time and then go for the tune. Adding base mods like manifolds, headers, air induction systems and CAT back stuff is fine without a tune.

Holy bashing if he wants to build let him build the awnser is yes change your intake go ls6 or even a fast intake don't bother with the tuner waste of money if your gonna change cam heads turbo etc later your gonna have to get it tuned anyway
You could honestly throw a intake a set of gears and a set of headers and wake that car up completely until your ready to go bigger

As far as our cars gettin are asses handed to us at the track I've wupped on many a camaro etc at the track and then still drove home while there wives looked at my better lookin car and drooled
Btw 500 hp camaro only runnin 12s sounds like you spent alot just to get stock corvette numbers

 

I am at 5k ft, and I only have 6k in my 500hp Camaro. A 12.3 is pretty damn impressive to the guys out here with my set up. A stock C5 at this height runs 13's. "Many a Camaro" only runs 14's

I have never heard of a stock C5 Corvette having 500hp at the rear wheels.
And my Camaro will tear a C5 Z06 to shreds in the 1/4 mile, at 5k feet.
Never had my car at sea level.

Last year I played around with a C5 with a supercharger. He usually took me.
He was just a little quicker. If I ran perfect and he missed a little I could take him.

Ask any racer how much the altitude effects the car. It is just over a full second.
I can easily run an 11.3 at sea level and probably hit a 10.95 at sea level.

-----------------------------------

I have a specific question about the tuner.
Yes we all agree the car will need a custom tune when I turbo it.
Most of us agree it is best to tune after any upgrade.

Why would I not buy the tuner now. Then I already have it?
Even if I my dyno guy has a tuner, I will stead need one to
fine tune it at the drag strip.

-----------------------------------

I asked my turbo guy about the Fast 92/92 setup. He said sure nice set up.
But a waste if I go force induction unless I am just wanting to throw money at the car.
I really like the looks of that intake.

 

Wow your 12 sec car will run 10.93 at certain altitudes I've never heard anybody shave that much time cause of altitude maybe a tenth of a second
Maybe you should run a vtec like the other guys that shred corvettes like you they get crazy power
