My Single turbo C5 build


ANTI_VENOM

Recommended Posts

Victor-Andy...I don't think anyone's being a negative Nancy. I'm not sure what an average set of forged pistons would be for your build...just seems a prudent thing to do while the short block is being built if you're going to be running more than 6-8 lbs of boost. It would also be more desirable when you decide to sell it when you build the next short block

I was just jokin about the negative nancy thing. Its really not prudent tho. If you go on LS1tech and go to the boost section there are MANY guys that run some crazy power thru stock blocks. Click on the sticky-Boost with stock block reliablity. Just go thru all the pages and you will be amazed. 12-14psi will be just fine with a good tune from NicD. As you know, its not my daily driver so if it were to brake then oh well... stuff happens :3gears:

I personally know a guy with a 71 nova in Peoria. He took a 5.3 out of a junkyard,checked the bearings and boosted it with an MPT70 on 10psi and it makes awesome power and runs like a bat out of hell. He is stock motor, down to the rod bolts, headbolts, headgaskets, cam, etc. STOCK. NicD tuned it.

Mike-a few post that back the piston info:

This is a cut and paste out of the 2nd post you have linked above...

"camaroandreas made over 80 passes at 1360fwhp on a stock 6.0 with a head sealing technique called pyramid ringing. It's similar to O-rining, but uses metal 3 sided rings with the pointed sharp side facing the head. The rings cuts a small groove into the head when the head is installed. Other than that the long block was 100% stock."

Exactly... That car is absolutely nasty! I will be at half that power level with a FRESH block.

icukln-I think 10# is going to be the limit of a stock cast piston and even then you will get blowby.

Are you going to deck the heads? What is the compression of the 6.0?

Didnt mean to seem negative, just wanted to save you some headaches.

I have a TTi Stage X with 62/65s on it. At 17# it makes 925 at the ground (before nitrous).

I ran into a bunch of 'sinchas' on my build... you know since you are in there, you may as well do it...LOL

Let me know if you want to talk boost...

BTW.. where are you planning on mounting the single? In the rear? Most front mount singles have issues with heat... A rear mount 103mm would be sick though...

I am switching to some boost friendly piston rings. I dont think I'll get alot of blowby. I am going to have the heads checked and cleaned. If they need to be decked then they will be. The CR is around 9.5:1. I appreciate the concern, but I have done my homework and have been apart of a few LS turbo builds making 700plus on a stock block. Your car sounds like its pretty nasty! I will be aiming for somewhere around that number next year. Just looking to get my foot in the door and have fun this year. And as stated before... I have some personal goals I would like to achieve with the stock block.

So how big of a single are you doing and where are you going to put it?

I've got to talk to Brad at AFI but I'd like to put a t76 on it. And it will be where a procharger head unit sits. I'm not to worried about the heat. Turbo blanket, heat wrap and a heat extractor hood will get those temps down

That is the same place as the Cerra kit had it. The pro was that the turbo was up high. The con was there is not much room for the hotside pipes and EVERYTHING got brittle from the heat. Here is a link to all the fixes for that kit http://forums.corvetteforum.com/c5-forced-induction-nitrous/451309-solutions-to-cerra-turbo-kit-problems.html You may be able to save yourself some coin by buying an old Cerra kit. They are going for about 3-4k on the big forum (if you can find one) Google Cerra turbo corvette and you maybe able avoid duplicating previous mistakes. Good luck

I'm pretty familiar with that kit. Mine is being built from scratch by AFI turbo. Itl will be similar but much better. Also, check out hinson's kit. Ppl haven't really had heat issues with that one either

The bad thing about the high turbo in the C5 is all of the plastic mounting for the radiator support and shroud up top. also watch out for the hood paint as i have seen a few that have gotten hot enough to discolor the hood.

Yea, thats one thing the turbo blanket will help with. Brad is making me an alluminium coolant expansion tank to make more room for the turbo as well.

UPDATE: New wheels!

new wheels...

Well you aren't going to have a daily driver anymore! Nice tires and wheels you'll get about 5000 miles on the street with those!

Are you going to upgrade your brakes? The stock brakes will not help in a high power run and a need to shutdown quickly? I know the z06 brakes would help alot!

Buccaneer-Looks like drag car only stuff, is that what you're doing Andy?

Still a street car for sure... I have always been a drag/street racer, never really into the road coursing and such. It will have street radials on it and only come out on the weekends.

MIKE-Well you aren't going to have a daily driver anymore! Nice tires and wheels you'll get about 5000 miles on the street with those!

I havent used this as a daily in over 5 months. I bought a Subaru Legacy that I daily drive. Ill be ditching the M&H Cheater Slicks for a set of MT Et Street Radial II's. Either a 295/50/16 or a 315/45/16. In the last 2 years I have put 4200 miles on the car so I'm not too worried about that lol

My brakes are pretty good for now. All of my suspension and brakes are from an 03 Z06, however I do have C6Z shocks on it. I have a set of HAWK pads as well. Stops on a dime.

Well, I certainly wouldn't recommend 12-14 psi on pump gas at all and even then with stock pistons/rods I wouldn't recommend it with E85 even though I've done it before.

Just put some forged stuff in there while it is out, if possible, and save yourself the time. If not, just run whatever you want until it blows up, and then build it. I run 10lbs on pump gas and 15 on 110. I make around 690 on pump and 830 on 110. I do have a built motor though. I was running 10-11lbs back with my Novi and stock motor on pump. I look forward to seeing your results. I am assuming the stock motor worked out while you had it. Good luck, Andy.

Still just doing pump gas this go around... but now I'll be able to run a little more boost safely. After taxes come around it will get a built tranny and 2 step and then I should be in business for some track fun! I'll be more than happy with that until I save up enough for the fuel system and then its on to E85 and we will see what she can do! Drivability and MPG will be awesome with the zr1 cam as well. Cant wait to finish this thing!

Ok! Sorry for the wait guys! Been super busy with work, moving, and a preggo wife that is due next week!

Ok, so the motor is at Standard Machine. They have had it for about a month now. I call yesterday and they havent gotten to it just yet : ( BUT, I have heard they do good work so I am being patient! They are re-drilling the crank and installing a chrysler crank bolt, hot tanking the block, ALL new bearings, porting coolant passages, bead-blasting the pistons and coating them. They are also, cutting my flywheel and freshining up my heads.

I decided to go with a different cam so I bought a custom ground turbo cam for my setup. Its a 228/228 .585/.585 on a 114 lsa. Should net me some more power with a better power band and still be very streetable.

I bought a set of new LS7 lifters and come comp cams pushrods as well.

Bought a C6 LS2 oil pan to get rid of the wings and make room for a larger downpipe.

Sold the slicks and got these:

295/50/16's MT ET Street II's

Planning on selling the RST Twin Disc Clutch and going with a monster level 6.

I'm thinking about selling the MN12 Z06 tranny thats in the car and going with a built MN6 for the longer gears but not sure... I'll try to remember to update more often!

I wouldnt do the MN12. Just build your MN6. The 12 is not as strong as the 6. RPM did my Level 5 tranny. Works great. I run an OZ 700 textrailia clutch. It holds the power and has a good feel to it. 30k miles on the clutch and the last time I had it inspected it showed almost no wear. The magnets in my tranny show no shavings either. What wheels are 16" that fit in the back without grinding the rear caliper? I thought you werent making a drag car?
