Well I am ready to upgrade my turbo. My question is which one to go with. My mods right now is a 0 plate, BHAF, and 4" exhaust. After a turbo I plan on a GSK kit and maybe some injectors or DV's. From what I have been reading on here a HTT turbo would be my best bet. Which size should I go with? My main concern is egt control as I tow heavy sometimes. I would like to have good spool up but don't want to sacrifice egt control at all. Just curious on what you guys thought.

 

I think your stock turbo is fine right now honestly. A stock turbo should support a plate, and GSK fine. Also; advance your timing. That really makes a big decrease in EGT's. I wouldnt worry about a turbo until I went to 370 injectors. Just my opinion.

im going with eric here, i dont know all that much about the undervalved guys, but it sounds like your stocker will be just fine.

yes the timing helps quite a bit!

 

Thanks for the help guys, but I can bury the throttle right now and reach 1300* in just a couple of seconds. Smoke is horrible as well.

 

whats your timing set at?

 

What kind of boost are you making? Sounds like maybe you have a boost leak, or need a boost elbow(if you dont have one already), and I would still do the timing advance before anything. From 0-60mph or so I could have my 1500* pyro pegged before advancing the timing. Now from 0 to however fast you want to go, it will be from 1300-1350* since i advanced it. You should have some smoke on the bottom end, but once you get boost, it should clear up. A bigger turbo will only make your bottom end smoke worse because it wont spool as good. So I would start checking for boost leaks first, then do the timing advance, and go from there. You shouldnt need a bigger turbo for your combo. Let us know what kind of boost you make at wide open throttle first though so we can maybe help you out.

I'm sure there is a post on doing the timing advance, could someone point it out for me? Or better yet a link, I need to do the timing and KDP soon. Thank's

 

Im sure someone has a link. You can do the timing yourself, but the thing is, the tools to do it will cost you qite a bit. I paid someone to do mine, but im sure ill eventually want it higher, and If i can afford it, I will buy the tools then. I think there is a link on how to do it on Genos Garage, but I dont have that link. Maybe someone else will chime in.

My timing is stock right now. I don't have any boost leaks because I can hit about 33 psi. It will smoke badly all the way from bottom end up. I was wanting to keep timing stock because I dont want to blow a headgasket. I plan on adding more fuel after I get a turbo I just can't do it right now because I can't use all the fuel I have now.

 

A turbo really helps without injector swap! and advance your timing wont blow your headgasket easier, unless you make over 45 psi boost! the Htb2s are wastegated somewhere at that point, to be safe!
PM me for a place to get $300 bucks off on new HTB2s

 

You should do a couple things before you get the turbo. GSK will help with street manners and egts a little, then timing to 15-16 area will help 100 at least. Then worry about a turbo. Timing will also get rid of some smoke and add some power. You won't blow a headgasket unless ypu get to 19+.

Don't spend more money than you have to IMO.

 

Well guys, just went camping the last few days and pulled a small single axle trailer with 3 4-wheelers on it. When pulling steep grades I coudn't give it half throttle without pyro on 1200. Before the fuel plate I could go as hard as I wanted to with a gooseneck and tractor and never get over 1000. I'd rather not have the extra power if I can't use it. I am gonna try sliding the plate all the way back for now and maybe try to advance the timing a little. But I know there is no way that my stock turbo will handle a gsk and dv's even with the timing, or is there? If it can be done i'd sure like to save the money on a turbo. However I do pull some and do not want to have to worry about egt's.

 

I would try timing it to 16.5 before anything else. Your timing might have also slipped from stock since it left the factory. Then see what it does to your EGTs and power before you get DVs and a turbo. If you get the DVs you will most likely need a turbo, especially with big ones. I run the setup in my sig, with the plate about center, and have no real EGT issues. I also live at less than 1000 feet in a pretty flat area. I'm sure that helps some as well.

 

16.5* of timing will be perfectly safe...even towing heavy! I ran 17* and towed with twins for a while...no headgasket issues!

Do you have the wastegate blocked on your turbo, or did the plate come with a boost elbow??

Also, is you're truck an Auto or stick...the stick trucks will have a lot more fuel with a 0 plate than an auto!

The truck is a 5 speed. I just got a boost elbow I am going to install. It will already hit 32-33 psi though. I am going to seriously look into the timing, I just don't have the tools or really want to pay a small fortune to have it done. Thanks for the help.
