Re: turbo ?
Sure ,no problem
I would say if you go w/a 20G turbo & a stock converter try & get a 12 CM turbine housing.

Re: turbo ?
"But,unless you have a loose converter that stalls to 2600-2800 RPM range,the 14 CM housing is too big for quick turbo spool up."
2100-2200 "STOCK"stall is not enough. :tup:
That is why I stated this earlierTYTILIDIE said:

Re: turbo ?
I can't argue with you there since I never had a stall that low with the 20g. You win :lol:

Re: turbo ?
You cna get a 2500 stall done with your stock TC for dirt cheap, around 200-300. If you wnat a better quality, you can expect to pay 4-900. IMO, the cheap 2500 will work out great as long as you have someone do it who knows what they are doing. I had a lot of people tell me not to do that because they are cheap but I honestly never had a problem with hte ones these local guys make.

Re: turbo ?
anyone have an opinion on the waller modified stock turbo i was reading his thread and would it spool quicker with the stock TC and how would it compare to the 20g

Re: turbo ?
It will rev close to the same as stock,maybe a bit quicker because it will get more air to the engine sooner.
It will have a bigger compressor wheel than a 20G,but it will also be restricted by the small 8CM turbine housing.
ALL in all, IMO,,,I would say for a stock converter Syclone,,,the Waller turbo will be stronger low to mid range,but give up a little on the top end over a stock TDO6H-20g turbo. It is because of the small 8 CM turbine housing.
Better drivability w/the Waller turbo = more fun.
You can get a 12 CM housing for a Waller turbo that will bolt right on, then later if you decide to go w/a TDO6H-20 G turbine wheel,you can have the 12 CM housing machined to fit the 20G turbo.
Make sense?

Re: turbo ?
yea
also i was considering some mods like vortecs and rollers along with pistons etc. would the waller or the 20g be better go with for the mods i plan on around 400 hp so i have been reading a great amount on here on which would serve me better towards the mods i would like

Re: turbo ?
My Syclone made 386 HP w/a TDO6H-20G w/a 12 CM turbine housing & 550 ft lbs of torque,w/21 PSI boost pressure
My engine is 100% unopened, untouched long block.

Re: turbo ?
those r good number and what i understand is that you can pull around that with either turbo does the 20g on your truck spool fast?

Re: turbo ?
It used to spool really fast w/a stock 8CM housing,but it did not pull great on the top end.
it spooled pretty quick when I had the 12 CM housing on it.
Now the turbo has a 60-1 compressor wheel in it.

Re: turbo ?
If you wanna read up on some combos and what kinda ET/MPH they run for pump gas & race gas boost levels, check this article on my website:
Syclone Modification Stages
It depends on what your goals are. You gotta make up your mind what combo you want to build and then get a turbo that matches for the boost pressure you plan to run. If you do vortecs and a cam then you should get a turbo at least as big as a PT51 IMO, all the way up to a PT67 if you plan on running 25+ PSI Boost on high octane. If you're never gonna run anything but pump gas it would be pointless to get a huge turbo and counterproductive.graham1524 said:

Re: turbo ?
ok i read the article and im aiming for stage 2 that deffinately sounds like what i want but i also want to go in and replace a few things in the engine to clean it up because how it is it really needs a decent rebuild going off of a stage 2 build what could i expect with stock heads and a roller cams and at that point id expect to stick with the waller upgrade
