Hey guys ive got a few turbo hondas and other cars. Im gonna build manifolds for the 5.3 with a passenger side single turbo mount. I want to do a water to air .
Im wondering whats a good size turbo for this application. Just want 450-500hp quick spool and decent power.
Any advise ive looked and the builds are bigger then what im looking for.
105mm.
You can get that HP with a way smaller turbo. I have a 76mm turbo and make 487 to the wheels with a stock 5.7l on a hot day with a very stingy Mustang dyno.
Single 70 or 76 will make it easy.
Figured it was obvious i was BSn
Well dang g. U know it's go big or go home lol.
What brand turbos are you guys refereing to? Sorry im so stuck in the turbo import world lol.
Like i said i dont want lag just want something 500ish.
Also wondering in normal driving on a good tune you guys notice a increase in MPG ?
Master Power, Turbonetics, Borg
talk to ducky man he has a strong turbo 5.3 with 5xxrwhp. And he drives it alotQuote:

Im running 70/96 on mine with a single front mount air to air and I drive it all the time. Theres also guys with 4.8s running 76/96 on theres.
What he said ^Quote:

Magnums are not the same turbos, they are just for the most part built to the same specs as the Master Power. The same guys who were importing the MP's started the new Magnum line with another turbo MFG company when MP stopped importing.Quote:

So I guess the question is are the Magnum turbos as good price wise and performance wise as the MP's were?Quote:

They're about the same price, maybe a few bucks more, but performance seems to be just as good if not better. I have a Magnum 72bb on my truck right now and it's performing very well. Allen is running a couple on his truck and I believe he is happy with them too.Quote:

Well picked up a MP T70 with a .81A/R.
now for injectors i was looking at 60 lbers
Hp tunner pro for tunning
Ive seen some kits run a 38mm wastegate and prsonaly seems small so i was gonna start with a 44mm ??
Fuel pump just a 255 or 310 walbro what ever i can find in the shop.
Tial 51mm BOV
I want to run a water to air intercooler ifi have the room. As im a 99 silverado and want to keep ac so front nose room is llimted for a front air to air.
Anything else im forgeting ? What map sensors do you guys run ?
I also scored a LS6 cam for the build

Front mount intercoolers are actually pretty simple to build and mount on these trucks. It can be mounted in front of the radiator without too much difficulty. I would say the 38mm WG should be fine unless you plan on lots of boost. As for the fuel pump I would suggest a bigger one like a Walbro 340 or bigger. If you plan on spinning the motor up over 6500rpm I would suggest getting hardened push rods and some better valve springs LS6 springs should work great. Good luck! Sounds like a great start on an awesome build.
What kind of truck do you have? Trucks weigh more than most hondas...more mass to push forward...tranny is gonna take a beating unless you upgrade that also. I went through a 4L60 in about six months on ten #. HP is gonna find the weakest link in the chain. Just sayin'....
Hey guys thanks for the input.
I got LS6 valve springs and LS6 cam going to look for some hardened push rods. The 4L60 is going to get a mad dog stage 4 rebuild kit. Ill build it soon.
The truck is a ECSB Z71 with 24's lol for now till i find some 20's i like. I kno the 24's are heavy but got them with new tires for a steal.
I was looking at the walbro 340. Im still debating the intercooler either ill do a front mount or a water to air. I find the 99-03 silverado has a small nose grille area.
If i do a front mount i will have to relocate the trans cooler as there is not much room behind there. I wanna keep my ac.
Buy my turbo kit, it is for sale in the forums. You just bolt it on. I made 442hp/468ft.lbs in a ECSB Z71
You can keep the ac. Mount the tranny cooler in front of the ac condenser and the intercooler below the radiator.Quote:
