quick spooling turbos?
i have a 5-speed 24v and the gear gaps can get in the way sometimes. i heard that alot of these aftermarket turbos spool ALMOST as quick as the stock hx35 with a 12CM exhaust. are there any turbos that will produce alot of low-end boost (1150ish RPM) in the aftermarket? will switching to a 9CM housing from an auto truck along with a 60mm comp upgrade work well? im not to concerned about choking out the turbo with a 9CM since im very rarely above 2k. im sure a set of mach 1.6's, a cam, and a programmer like quad adrenaline would help alot to but im on the turbo side of it and i dont have the time/money for twins right now. please offer your thoughts

I'm going to jump in on this.... I also want low rpm turbo spool up.... The only time I go above 2000 is on the highway and when I go there... I drive like an old man...lol don't care about high end.... I want that turbo off the line for plowing snow at low speeds

The little hy35 does spool almost instantly. I ran one with 125 horse injectors and a drag comp for a long time. Just hated to give up the instant power but it did choke bad above around 2400.
The later he351 has the bigger wheels and the small 9cm exhaust housing. I've never ran it as a single but am well satisfied with it in twins. Big Blue24 could tell you more on this turbo as a single. Do a search and you'll get plenty of reading.

There are a lot of different turbos on the market. I had to replace my HX35 just the other month. I bought a BD Super Bee. It spools very quickly and is a good turbo for twins. The other turbo I looked at is an Aurora 3000. It is a great turbo also. The housing size is where to be careful. If you want quick spool like stock stay around a 12 or 13 mm. Anything larger causes more lag.

If you are actually still going to upgrade your turbo, buy all the modifications and match them to each other.

that stock turbo off a 04.5-05 sounds like exactly what i want to start with!!!will it bolt up to a 2nd gen manifold? and what exhaust pipe will i have to buy/fab? can i upgrade the wheel to a 62mm or sumthing? im aware if i go to far i will have horrible surging problems and choke the motor sumthing terrible, but im willing to play with things these aftermarket turbos dont sound like sumthing im after with my truck... besides they are a pit pricey for me anyway

Yes it will bolt up but you will have to do something on the compressor piping.Probably fab a 4 inch exhaust and I doubt it can be upgraded. If you were going to do that you might as well use the 300 series turbos everyone is using.

you cant have a turbo that runs well on top end w/ the sacrifice of spool up. and you cant have a turbo that runs well on low end w/o the sacrifice of top end. The only way to have both is to go with twins and the best short shifter you can find

You mentioned a cam in your original post. You might want to look at it from a bit of a different angle and consider just doing a cam. It will certainly help airflow down low as well as all the way through. Then later on if and or when you do other power upgrades it will benefit those as well. You can get a cam for 500ish (f1's are 488,, local guy here has a grind for 525) and if you can do the install it will be fairly cheap. Even if you cant do the install it wont cost anymore than many of aftermarket turbos and less than some. Though it wont be cheaper than swapping in someones older hy that you could pick up for cheap depending on the fab work you would need to do. If you rarely go above 2k rpms you wont need to worry about springs etc either. A side benefit is you might see an mpg increase as well.

From what I understand that you need springs for the F1 cam. It will spring binds up, so I think you'll need springs. My PDR cam, no you don't. Installing the tappets install is a pain in the butt.
I vote for a garrett ball 3782R stage 2 bearing unit or twins if you want fast spool-up with lots of air. You should run her out on a few gears and hear the turbo spool-up. The cam, injectors, ported head and fueling hard box all help to get things spooling. I bust the tires loose going from idle to wot right from a stop. The air is thinner here, down at sea level, my truck would alot more responsive.
