If all goes well, I will have a set of 370's pretty soon, and as Pete has told me, the stock turbo won't like it with a turned up pump. After the injectors and pump mods, I'm going to leave it alone, (except for improves airflow later) and I have to make a turbo choice. Will the 62/71/14 be too laggy for my set up, or would I be better off going with a 62/65/14? Would that be big enough? I don't want to buy more than one turbo (unless I'm doing twins) so any help, or experience would be appreciated.

Or, would a simple and cheaper HX40 do?

Does Bill still have the HX40 with the 16cm housing for sale? I may go that route, because I probably don't need the S300, and I shouldn't really worry about barking the turbo with an auto right? I believe Philip said barking is more of a problem in manual tranny trucks.

I went with the 300 because I love to bark.

:lol:

Reminds me of a Golden Retriever we used to have that would eat bumble bees. :lol:

What is your dogs name?

Richie, did you research between the HX40 and S300G before you bought your turbo? Did you say the S300G would outflow the HX40? I might go in that direction as well. I'm not sure if it would be big enough though. If it isn't, I suppose I could rule out an HX40 as well...

His name is Andrew.

I was told by Borge Warner tech named Curt Henderson the following.
My turbo is a base S300G.
He called it a 57mm compressor 64mm exducer 14.77cm exhaust housing.

So that would make it the 57/65/14

He said it will suport 350 to 400 hp. I assume thats flywheel hp.

He said it was happy to 45 psi

He called it a replacement upgrade from a hx40.

It flows 60 pounds per min ( what ever that means )

It flows 870 cfm's max. ( I am sure he said that is more then the hx40 )

The guy at my local cummins shop said he would not sell me a hx40. I know alot of people use them and they are a good unit but he does not like them. He talked me into the s300. I trust him. He grew up here in town and have known him forever.

Do you know how big 370's are compared to stock Non I/C injectors? Are 370's 5X.012, and Non I/C 4X.012?

How hot will your set up get if your heavy on the go pedal? I may have to go with a bigger S300.

Skilletky, you have 370's correct? You also have a 62/71/14 right? I remember you said it was a little laggy off the line, but other than that how do you like it? With your set up, hoe are the EGT's?

by **sdstriper** » Wed Mar 04, 2009 10:46 pm

If you look in the injector thread up there I believe they are 29% larger than the non I/C...

It will get hot. I can hit 1400 with the timing 3/16ths advanced. One thing to remember. Pete is running his with a 60mm upgraded turbo. I am sure mine will outflow a hybred rig. NOT POOPIN ON YOU TURBO PETE. I am going a 60 mm upgrade and a 16 cm on my 93 with a set of pods. Gonna bark her til she poops. I know you only want to buy one turbo. Its a hard choice. I could have gone bigger I'm sure but for now its ok. So far I am only boostin to 35 pounds. I got 10 more pounds before I start getting hot air.

I know yours will outflow a hybrid, and Pete warned me not to go the 60mm comp. wheel route.

Does anyone have experience with a 62/65/14? I believe those were the specs... Supposed to light faster than the 62/71, but would it flow enough air?

Well I got the 62/71/14 and I can tell you that spool up doesn't seem to be much later then the stock non ic with a 16cm. But I didn't dyno much more power over the stock turbo but its feels way more powerfull

by **randyswelding** » Thu Mar 05, 2009 8:36 am

i would say the 62/71/14 you got more room to grow,i got 370s the timing is bumped bout 3/16" and no afc and the fuel skrew maxed.it is a little lagy but not enought to worry bout.your lighter than me so i dont think itll be that noticable for you. hope that helps
ps i got my 62/71/14 turbo from industrial injection its the super phat shaft and i hit 44psi at 2k on the tack about and keeps it there until i let off with only 1350*

thats what i ended up with

62/65-13ss

the 13 stainless housing is a htt sales pitch

spools like a 12 but flows like a 14

some people like em (i do) and some dont

guess every truck is different which makes the odds of getting the exact right turbo first time pretty high

i tried to contact htt to do a comparison for them. we were talking about it but i lifted the head on my truck. now that i have it fixed they wont respond to my emails or return my ph calls. i would use ii if i were gonna do it again

i think you are on the right path with what you are looking for (62/65 for a first gen)

have fun - promise you will - makes the truck totally different animal

i think either way you go, you will be happy. i am very happy with my mine. the lag never had bothered me, if i am at the track, i will give it a little power brake to about 5 psi. as soon as the light goes green and i punch it, it shoots right to 45 psi. as far as street driving, that is were i noticed it. about like having a 18 cm one the h1c. i can't give ya an accurate answer on my egt's. the most i every seen was about 1000 to 1100. my converter was about fried and the trans was slipping the day after i put the turbo and injectors in :grin:

so it never really put a load on the engine. that may have something to do with the lag. i aint got to drive it yet with the new trans. still waiting on a diff :evil:
