So the direction of my build has changed. Decided to get away from my H/C Nitrous LS1 and go to a Turbo 5.3 build. New to F/I and getting a FULL parts list together to start chipping away at it. Hoping to be done sometime late next Fall... Please chime in if you have any parts lists for a build similar to this or any suggestions. Goal is 700 wheel.

What I already have:

Ported 317's
5.3 Shortblock - Stock Crank

What I need:

Pistons (best turbo pistons?)
Rods (suggestions?)

Best turbo size for quick spool and 700 wheel goal?

Like I said, just starting a list, any suggestions or recommendations would be great.

 

Do a search and read how other have done their setups would be your best bet. Plus you need to add more details. What trans, fuelsystem/type of fuel, daily driver?
Few more things that I'm not thinking of now. Plus I think your 317's will make it a dog out of boost also.

 

Well you can get all he piping And a basic kit from huron speed, youll also need a fuel pump and injectors to support That hp. But you still need pusher fans, oil feed/drain to the turbo, Alternator relocation, new valve springs, push rods, an oil pump, And arp head studs to hold the extra pressure. After you have all this new power you have to get it to the ground through a decent clutch and a built tranny and rear.

 

get a tc78 /76 turbo, thats what i have and it will exceed your power goals and spool up QUICK with the right cam setup

 

Did you get your car on the roller with the new Turbo?

This guys has a nice setup

 

Already has a Moser 9'' and a Monster Stage 3 clutch.

As for fuel going with twin 255's & 80's

 

What cam are you running? Custom grind or something like an LS6

 

What do you guys think about this group buy? Good product included?

And I already have springs and pushrods to support it

 

Custom grind for sure, i dont even see the point of wasting time/gaskets and money on swapping cams for some other "stock cam" . right now coloradospeed has a sale for 360 for a custom grind which is a killer deal. so i would hop on that deal

 

Ok thanks for the heads up. Any comment on that Huron Speed kit?

 

I wouldnt hesitate to jump on that huron speed kit. A few people on here and have had success with the kit and his customer service seems to be great.

 

Im going with the huron kit on my 5.3

 

yeah a lot of midwest people go with the huron kit, im debating on one this spring, have heard and seen nothing but good things from it even with people running ON3 turbos

 

I have the huron kit and I have no complaints. Instant spool, good quality... May down the line stand up my radiator and put on a different turbo, but for now the On3 is killing it!!!

I'm running the EPP blower cam
It is a strong running bastard.

If you are only shooting for 700 hp.. I would leave your bottom end stock. Seriously... I personally know several guys running over 800 rwhp on stock 5.3 bottom ends with NO problems at all. Just switch to head studs and ls9 gaskets

 

I would like it to last and be ready for more boost if I were ever to want it and for the price of forged rods and pistons is worth the extra peace of mind

 

the EPP cam is good, but its designed for BLOWERS! turbo cars have different needs than a supercharger, so a BLOWER cam isnt the best choice... what i would personally do.. and this is what i personally did, was email up Patrick G, very well known on the forums for his custom cam grind, pay 25$ and get him to grind you a CUSTOM CAM! to your specifications and needs, then buy a custom grind from a sponsor for 360, and for 385 you will have the meanest possible cam and optimized for YOUR setup, your heads, your intake, your motor, your power goals, etc.... why buy an off the shelf cam when a custom cam is the same price and you can gain an extra 50-100 hp at same boost level?

 

Can you weld/do you own a welder? Building truck manifold kit yourself is very simple and can save you some coin. For me personally, the ls6 cam wasnt an option. Having owned a V with the LS6, I knew that it didnt have the sound that I was going for. I wanted something that had some lope and sounded good. I just knew that I wouldnt be happy with the LS6 (personal preference). I picked up a comp 224/230@114 on craigslist for $100 to my door. Dont discount any of the turbo friendly NA cams, especially if you can find a good deal on one. As for the 317 heads, I would try to avoid them. If you have a lot of money in the port job and are dead set on using them, you may try to pick up some 4.8 pistons (if staying stock) or forged pistons that will raise your compression.
