help picking turbo

[Syclone #1188]

Did alot of research,reading and still cant decide what turbo I need. Right now im leaning toward a pt51. I have the motor out now for a rebuild, so now is the time to upgrade to better heads and cam. I have a 96 blazer donor for the heads.


Going with the following mods, some are already on the truck..

255 pump
fuel pres regulator
3" exhaust with straight threw glass pack, no cat
chip...thinking of going with a turbo tweak. (going to have to invest in laptop for tunning)
3bar map
wide band O2
vortec heads
412 cam
forged pistons
ans boost controller
Stock converter (tried a 2800 stall once, didnt like it for street use, the trans temp shot up)
meth injection( can only find 91octant fuel in my area)

Want a streetable truck that runs low 12s high 11s. Whats the best place to get a turbo from?..just the turbo. I can make my own down pipe. Will be doing most the work myself, mechanically inclined person.

My other truck is a chevy luv with a sbc 350 runs low 11s. Its alot easier to get those times with it. Its a totally differernt game working on the syclone. I can tune a carb no problem but fuel injection and turbo is a whole new game. I have been reading up on tunning the syclone and will be reading alot more about tunning.I will be asking more questions about that later. From what I have read so far, a good tune is the most important thing!!! Right now Im focused on the build, get it running again. Then I will focus on the tunning issues I will have.

Back to picking the turbo. What do I need to get the job done without a over kill? Leaning toward the pt51....any and all advice is greatly appreciated!!

I'm selling 2 different Garrett turbos, one packs a powerful punch.

Re: help picking turbo

Mitsu hybrid. 60-1 (or 25G) and a 11 blade (or 9 blade) TD06H turbine. 14 cm housing. Billet wheel will spool a little better.

Best thing is that it's totally bolt on.

To kinda cut in on this thread would you say this set up would complement a 2600 stall or would a 10 cm housing give better results for a more street driven/stop light fun machine?

To the OP, the above setup was recommended to me by another member but with the stock 8cm housing to negate the effects of turbo lag. If you are interested hit me up and I can shoot you part numbers for some of this stuff.

The stock stall converter is going to limit your choices. I would do a PT5858. PT51 is outdated, but it also has too large of an exhaust wheel.

If you want a stock appearing mitsubishi don't use a 14cm housing, it is way to big esecially for a stock stall converter, I would do something like a 20g or 60-1 wheel with a TD06H exhaust wheel and 10cm housing.

I know for a fact that this 20g /10cm setup works great. I just installed one on Aaron's Ty and he loves it. He does have a AEM boost controller and Forge waste-gate so I know that helps this setup alot. Happy Hunting!

Re: help picking turbo

Is there any recommendations for those same peramiters but with an externally gated turbo?

 

[The Devils Own Chariot]

Re: help picking turbo

Mitsubishi Heavy Industries
TE06H-24v
Part NO. 8976922201
Turbine Housing A/R: 12cm^2 with T3 Flange
Turbine Wheel Exducer / Inducer: 55.8 mm / 66.3 mm
Compressor Wheel Inducer / Exducer: 55.5 mm / 77.9 mm
Flow Rate: 800 CMF @ 1.0 Bar
Its close to bolt on and its reasonably priced.I think I paid $650 for it...Made 590hp at the engine with it. Im sure its not that great compared to the really expesnsive billet wheel turbos or ball bearing. It comes internall gated or externally gated. I have the externally gated one.
This might be old news now but I have never heard of anyone complain about the GT35R turbo.

Re: help picking turbo

Did you already install the Cam? If not you might want to look into something different than the 412.

Re: help picking turbo

Subscribing to this since I'm doing a similar build over the summer and the turbo is my wild card atm. Got everything else planned (i think...). Just haven't decided on a turbo. I'm remembering correctly that the stock turbo isn't good for much past 12.5 seconds?

Why would the 412 not complement a 60-1 out of curiosity? I simply don't know enough about the factors of boost and engine components to put it all together.

Re: help picking turbo

Im thinking there are a lot more players in the game than just a cam when it comes to engine volumetric efficiency. I would still like to hear the responce on why the 412 cam would not be the best option....

 

[nastety92]

Re: help picking turbo

From what I've been reading lately, in the past 1-3 years, most people have been shying away from the 412 cams since they are not turbo specific. Going with a customer grind cam is what a lot of people are doing these days.

I had one in my engine and we pulled it and we are putting a customer grind cam.

What about the 422 cam's? I was going to go with that one.

Re: help picking turbo

422 is very "aggressive", for the n/a crowd at least. It's also around the same price that Steve Morris engines will charge you. I'd go there. I have a 415 and wish I had the option of Steve Morris at the time.

Re: help picking turbo

I would go with a 60-1 billet wheel. http://shopping.kinugawaturbo.com/mitsubishitd05td06turbocompressorbilletwheelgarrett60-1.aspx

This compressor cover http://shopping.kinugawaturbo.com/turbocompressorhousing24td0620gtrustsgmc-1.aspx

This turbine wheel. http://shopping.kinugawaturbo.com/t...sl220g11bladesubarudsmlighter9blades-1-1.aspx

You will have to get your 8 CM turbine housing machined to fit the larger turbine wheel.

You could just buy a completer center section like this & ask for a billet wheel & 9 bladed turbine wheel (for additional cost)
http://www.ebay.com/itm/Turbo-Cartr...Parts_Accessories&hash=item2a3ba6f0f2&vxp=mtr

The problem when the Buick GN & Turbo T-Type guys had early on, there was not much in selection on different size A/R's for the turbine housings, that and the stock class wanted a turbo to look stock on the outside but has a larger better flowing turbine housing. A "Cheater" turbo.

Getting back, since you want to use a stock converter, & want more power, you need to allow the engine to breath better in the exhaust, the one way to do it is to install a larger better flowing turbine wheel.
Using your small 8 CM turbine housing will have no problem spooling up a larger turbine wheel & larger 60-1 compressor wheel.

I currently use a 12 CM turbine housing machined to fit the larger "H" wheel. This is the largest A/R turbine housing you can use & still have great spooling w/a stock torque converter..
Do not listen to the guys that say the 14 cm housing spools just as fast as a stock turbo, while using a stock torque converter, DO NOT FALL FOR THAT, it is not possible,
I currently run 12.0 w/my hybrid turbo, it is a low dollar build I did most of the work myself. The engine is 100% stock.



I use a standard 12 bladed TD06H turbine wheel (LOW FLOW) & a cheap cast 60-1 eBay compressor wheel.

Stock VS Hybrid


I had machined a 10CM housing, it spooled just as fast as stock, but the extra top end pull was not there, not until I installed a 12 CM turbine housing, then more top end power came in.
Here is a 14 cm. 10 cm, & a stock 8 CM housings

Re: help picking turbo

Uh yeah the 12cm housing makes a huge difference on top end. I noticed that imediatly before anything. It was like the truck decided it was not going to stop at 100mph any more. Felt "supra ish"
I see this site sells the turbo I recomened. It must be more desireable now. They want $1000 for full turbo now.
http://shopping.kinugawaturbo.com/k...urgete06h-24vwitht3v-band10cmbilletwheel.aspx
That billet compressor wheel is a nice price.
If you buy any parts from this sight and put it together yourself I would have everything balanced at a shop that does that sort of thing. You might not need to but it’s a good precaution. When I got a new compressor wheel for mine I had a diesel shop put it on their balancing machine. Just would suck to not be 100% sure its ballanced and screw up your entire setup.
Here is a pic the old compressor cover vs new compressor cover. The covers that come with it sure are ugly.

People have had the stock turbo well into the 11's I'm in the middle of a big rebuild right now and went stock turbo upgraded with the sportmachines billet wheel and some other goodies they offer. I also talked to Alex at Steve morris and had them hook me up. I hope to have it running in the next week but my research has come up with this being a good combo

Re: help picking turbo

Oh, and of you keep the stock style compressor cover and you want to change the direction of the compressor outlet for say a FMIC then you can hit up Mike Renz for one of these little numbers. It allows you to turn the compressor cover some and still use the stock wastegate setup. I should get an A+ for posting today.

Re: help picking turbo

An ideal set up without changing out the torque converter is obtaining a 10 cm housing and porting and polishing to match the exhaust size...I got a 20g with a 10 cm setup....I lucked out...didn't know what size the housing was when I bought it...I just rolled the dice ...I did a lot of research to figure out how to properly identify the housing...I did a write up on it all with pics with Adam. ...do something that everyone else hasn't done and be a pioneer...imo
