GDS 60mm upgrade vs hx35
 

i have the stock h1c turbo on my truck and unfortunately i have the 21cm exhaust housing. so my question is wats the better deal for more get up and go plus i want some whistle :humm:

HX35=56mm 60mm=60mm.

so the h1c wit the upgrade is better than an hx35 and wat would be the best exhaust housing for either one

If your h1c is in good shape(no excessive shaft play), the 60mm is a good, cheap(ish) upgrade. The 14 or 16cm exhaust hosing will let you spool up way quicker than your current big a$$ housing does. I went from 18cm to a 14cm housing and it's unbelievable the difference. As far as a singing turbo, The larger compressor wheel will increase the "whistle" but will greatly depend your exhaust, to let the sound come through.

thnks muskrat so ur sayin a smaller housing is better? wont tht raise my egts a little? and im gettin 4" exhaust put on soon

No, It won't hurt anything. alot of stock tubros came with a 12cm housing. The 21cm you have now is rediculously big. Commonly known as a lag monster. You will notice a raise in EGTs, but a 4" exhaust will cancle that out.

ok thanks for the info man my dad is gettin me the gds upgrade for christmas and he got me hooked on the 1st gennys so would u recommend the 16cm over the 14cm or vise versa

What are you using the truck for? If you're towing probably the 16cm, daily driver/hot rod, 14cm. the 14 will spool up alittle faster, but will have a little higher EGTs. I love my 14cm, though and haven't had any issues w/ EGTs.

its a lesiuer truck no hauling except a dirtbike occasionally so i should proly get the 14cm right? and the egts should be fine with the 4" exhaust

Yeah, I think the 14cm is pretty well rounded. BTW have you gotten gauges yet?

thts wat i was just bout to ask u look at my other thread bout the spring and reply

---AutoMerged DoublePost---

do u think i would need gauges?

see other thread:tu:

Did I talk to your dad on the phone today?

Thanks for the link, that explains this whole thing to me. Told y'all I was a noob :c:

i read up on the gds turbo upgrade and its a super difference over just the plain old h1c. Everyone says its all the turbo u need if ur under 450hp. Creates good boost and power and doesent spool down quick in between shifts. Im gettin one for christmas :jump:

Running teh 5-speed I think I would go with a 12cm wastegated housing.

Everyone was wrong then. For a close to stock truck, the 60mm upgrade is alright. However, once you add bigger injectors, or turn the pump up on a Non I/C truck, it's pretty much useless. Richie O is making right around 300rwhp with his '89, with an S300G (much better than an H1C) and still has EGT problems.

If you want 450rwhp, a 62/71/14 S300 is the turbo you should be looking at, not an H1C.

:D:D I'm gonna go ahead and reply to this one. He's 16 and doing mild mods for now.

What does age have to do with anything? I was replying to what I put in bold. No matter how old you are, or if you're only doing mild mods, a 60mm H1C will still not support 450rwhp. Spreading information doesn't do any good if you spread the wrong information. I was simply correcting him, and I know I'd want someone to do the same to me if I thought something that turned out to be wrong. I wasn't trying to be a jerk, if it came off that way, but I didn't want him spreading false information either.

:ouch: Sorry, I wasn't implying that you were rude, I didn't notice the bold letters. I took it as you were just explaining to him that he needed a bigger turbo. I was missing the big picture. And good call, That turbo would have a heck of a time making that hp if it can be done at all, and if you put one on a 450 hp truck it would probably end up in a bunch of small pieces in a hury.:c:

sorry guys for saying tht maybe it was 350 hp cause 450 hp is proly to much for tht thing to handle i was wrong but im still learnin

well the upgrade woks better on my truck then the stock turbo set up. and i'm prolly only pushen 250ish hp. but 1400* is better then wrapen around past 1600* on the pryo so its a good investment till tax return time.
