Which Turbo for 2H? Photo added..

I have searched and done some extensive reading on the topic and have taken what info I can from the guys who really know their stuff on MUD and I've been getting pretty excited while doing it..! I am trying to start gathering all the ingredients for a homebrew for my 2H and want to start off with the right Turbo and then get the rest of the stuff after that.. From what I have read it seems that the Garrett GT2560 would be just about top of my list of Turbos to try and get hold of, the trouble is that I can't find a used or reconditioned one and the new ones are super pricey and then I might as well go for a kit from Turbo-glide or AXT.. I have seen a new KKK K26 for sale for about $US500 and I know that Tapage runs one of these or a similar on on his 2H.. is it a good alternative to the Garrett or should I keep looking for something else? What are some of the other fairly common turbos available that would be a good alternative to the Garrett? Stoked to be able to tap into the brainiac recource of the MUD addicts..!

I have been doing the same thing for a while now. Lately i have been thinking of the fesability of using a Holset turbo HX25 or HX30 on my 2H. But then i read the write up on the 3B that has gone compound and it blew me away and i've now been looking at what combination would work like that on my 2H, maybe a Holset HX25 with a HX35. Sadly though i dont think that will be a reality for me when the time comes for my turbo system.
 
I was also in the same boat as you guys. What turbo do i get for my 2H?? Well, after months and months of reading this forum. I ended up purchasing a 10k km Garrett GT2860RS (aka disco Potato) from some guy off of kijiji. That was looking to upgrade his turbo on his D-series civic. The trim sizes and .60 cold/.64hot A/R's seem to be close enough for me. In terms of comparison to all the turbos that are used in the kits people buy and what everyone seems to use. Except that fact that my turbo is ball bearing vs. kit turbos which are journal bearing. I will say for a piece of mind and a fresh start. I sent my Centre Housing cartridge in to a Garrett performance house for a BB service. Which is, they take your unit as a core and send you a brand new CHRA for half the cost of a new one.

I am just trying to gather everthing thing i need. 3'' alum intake pipe work, silicone couplers, T-bolt clamps, oil feed & oil drain lines, water cooling fittings, <--(all from racepartsolutions.com......cheap!) T3 5 bolt SS exhaust flange w/3'' exit, manifold to exhaust intake adapter (custom), gauges (boost,EGT,Temp,oil pressure) and im going to join the 3"club for exhaust. I think thats it. lol all said and done i will be around $1500 CAD installed.

When i start, i plan on posting a thread on it. Till then...im just filling the closet up with goodies for the HJ60!

Are you guys doing anything different aside form the Turbo?

Well i have a mate who is an engineer and is wanting me to go the compound turbo way with ported pre combs, skirt cooling and new pistons which would lower compression a bit. The aim was not for huge horsepower but heeps of torque on song right from the get go and still plenty up higher for passing/towing. Like i said though im still in the planning stage and slowly getting parts and still asking forum members too many questions (one in particular)!!
But at this stage i'm still liking the Holset turbos, dont ask me why although i think it has something to do with what the cummins guys put them through and they keep going.
My 2H will def get a makeover though at the very least before a turbo as it has 350,000 on the clock.

I think it will all even out. Turbo Glide uses T28 journal bearing old design turbo with a smaller turbine side trim same compressor trim size though. My 2860rs has a bigger turbine trim and will theoretically have more lag but is ball bearing vs. journal. Also, compressor housing design and size is different from each other. When i used TURBOFAST.COM.AU turbo match calculator. It ends up giving me a Garrett GT25 w/260HP rating and 0.63 A/R.

All things aside.....i will see how well it works for me and go from there. The GT2560 does sound like a good match.

Great opinions and options are endless.....in the end you will make the decision.

Let me know what you end up going with and how it works.

The ball bearing core will certainly even it out. I'll be interested to see how it goes.
The disco potato works best as a low boost turbo and the 2H is an engine you don't want to give high boost so it's not a bad match.

I hear the KKK's like Tapage use have many different variations, so you might need to do some careful checking to make sure you have a similar one to him.

Compound on a 2H is a bit silly. I think you'd have trouble with it first staying cool and secondly holding together. By the time you reduce the compression enough you will likely have trouble starting.

Your right it would be a challenge to keep the engine cool and together with compounds. I'm only looking at it not planning to go down that road no matter how much my mate try's to convince me.
 
I've got it boosting 10lb from about 1900 rpm and the egt will just touch 1200 deg F when working hard (guage is tapped in pre turbo). Also running a 2.5" straight pipe exiting behind the left rear wheel. I like it :D It's been running like that for close to 3 years now with no problems. :cheers:
 
I've been doing a bit more searching for a suitable turbo for the 2H and have come across a Garrett T3 for pretty cheap... any advice on whether this might work? Thanks guys
 
Would really suggest replacing the pistons on a 2H, that has some mileage on it and is getting a turbo, with Alfin type units that have reinforced ring lands. I've been seeing more and more (because we are taking more apart) 2H engines with very beaten up pistons due to ring land erosion - even at moderate mileage and easy use. Low compression, smoke and noise are the characteristics of engines with damaged rings/ring lands.

More info needed - what are the AR's for a start, especially the hot side.

any idea on the piston set price .. ?
 
Been giving all this some serious thought and have decided to bite the bullet and get a new GT2560 when I have the money... if that's the best one to fit.. It will cost me way less than bringing in a Turbo-glide kit and I will have a new roller bearing turbo where as the Turbo-glide kit comes with a journal bearing one.. I'm a little worried about buying a used turbo off the net not knowing what it's been through.. in the end if it needs to be rebuilt it could end up costing just about the same anyways.. In the mean time I've started looking for a used exhaust manifold so that I can get the adapter made up so long.. it will mean less down time for my truck when I finally do the job and also that if I sell my truck at some stage I can just bolt my original manifold back on..

Garry,
how passenger friendly is your exhaust?

care to share any vids? :D

thanks,

Ok in the mean time I've seen another turbo for sale and I thought I'd ask for advice again as to whether it would be suitable for a 2H? It's a T28 Garrett with a AR. 80 compression and AR. 64 exhaust... I think it sounds about right guaging from all the searching I've done on these forums but I just want to get the nod from the turbo gurus who might be lurking....
 
That will also work fine.
