anyone slap a disco potato on a 25?

[lucky7]

well, right now i cant seem to find it reasonable to do a love fab manifold, GT3076R, tial WG, custom DP, big injectors, etc etc etc. its just not financially a good idea for me right now. so ive been tossing around the idea of doing a disco potato (GT28RS, or the new 28) 'upgrade'. the pluses outweigh the negatives for me at the moment. its internally gated, and will give me just a little bit more power. stock manifold, dp, hot pipe, etc.

my issue is that my current wastegate is effing up. it likes to give me infinate boost, and my EMS cuts fuel like a mofo. therefore making life terrible behind the wheel.

would it be possible to make 350whp with the little GT28? i know the SR guys are getting close. but can the turbo flow enough for me?

any other suggestions for a 'cheaper' turbo upgrade? must be internally gated. i dont want to deplete my cash funds completely.

any added input would be greatly appreciated. thanks guys.

t28 based turbo, wont bolt on without some kind of adaptor plate and even then its too small for a 2.5l.

[craz4240]

I say some kind of T3 turbo is what your gonna want to look into,it may not be ball bearing for a cheap price but it will make 350whp.

ive not had time to research anything lately. SC61? haha. i need to read up on some stuff. off to do more work though...

Holset HX35 (or HY35 would be even better). Less than $200 on egay, GREAT spool, and you can turn up the boost and make up to 450hp later down the road. Bolt on a HX40 compressor (like me) and make over 500hp.

[lucky7]

i need something internally gated.

any GT30's come that way? on their site it says they're wastegated. but do not come with actuators. i wouldnt know where to get an actuator from...

[Carl H]

holsets are internaly gated...

Holset HX35's are the better of the two, HY35/HX35. I am personally pursuing a HX35 for my motor. They flow an insane amount of air for pressure, and price. The surge line on them is comparable to that of a GT35R as well. Bang for the buck IMO.

[Cjmartz2k]

Define better. HY will spool a little quicker, but HX will make more power. Sounds like he wants to go small. I would say HX though, because it'll give him a little more potential later, The spool difference is probably less than 500rpm, but I don't know. Also, if he goes HX, he can put the 40 front end on it later. I'm at 1.5bar by around 4000rpm in 3rd, and less than 4k in 4th. If you can deal with a turbine that spools like that, keep the boost under .9 bar or so, make under 400, and crank it up later when you get the supporting mods.

cool. thanks. ill start reading.

Just get yourself a t3/t04e 50 trim, .63a/r exhaust side, make sure it comes with the ford 5 bolt discharge, and then buy yourself a internal wastegate to bolt on it (prob. can find one at atpturbo.com) and be done with it... And then your turbo will match the quality of your build.Dont kid yourself you have a great looking car there and have done everything right so far, dont screw up and buy something cheap... Do it right the first time.

Get an internally gated 3076. All you need to get it to bolt up is a new dp and spacer flange between the manifold outlet and turbo inlet to clear the valve cover. That's all the power you'll need unless you eventually want over 500 hp.

[Bwana]

I'd just pick up a hx35 with a 12cm exhaust housing (factory manual trans Dodge Cummins turbo). T3 flange, internally gated, plenty of air for what you're talking about and very reasonably priced.

[meet07]

will that turbo bolt up the stock manifold???

[Cjmartz2k]

yup

[lucky7]

that sounds like a great idea. wondering why i havnt really ever heard anything about them before.

[Cjmartz2k]

The DSM guys run them, and so do Honda guys. Also, it will bolt to the stock mani, but I'm unsure if the compressor will clear the mani. If not, you could probably put a spacer in it. It's a T3 flange though. Ebay for less than $200.

[lucky7]

i did a little bit of reading on them. im shocked ive never really heard much about them before. sounds like a win for me. thanks again for the suggestions and help.

[Coolwhip]

Yea I looked into right after I saw what's his name setup running one.

I'm surpised how powerful, efficient, cheap setup up they produce.

Of course this revolation comes about when I sell my motor off

I just never win

[Cameron]

What about a T3/T4, woud that be a good setup on a 25.. sorry lucky for jacking your thread, but im also looking to upgrade my turbo.

[Coolwhip]

T3/T4 will run you a couple hundred more for the turbo it self but requires the same amount of $ and work to install.

The problem is that the T3/T4 doesn't seem like it will push air and produce power at rate this turbo is magically making.

Either option your going to get some umph but this HX35 has me sold in my head.

holy crap that is awesome!

[l0nestar]

I thought so too, but Carl and I were looking at it, and began to question it's accuracy

I really liked it for all of the maps it has.

[lilskyline240]

Holset turbos are some of the most amazing turbos ive ever seen. Spool Crazy fast for their size and make great power!!

Hx35 FTW

[Cjmartz2k]

T3/T4 what? Your just talking about flange sizes. My buddy is running a T3/TOe, and I know another guy running a T3/TO4r. You have to be more specific. Besides, just go for the Holset.

[Kalypso]

this thread is a real education, thank you

im runing an redtop but

does the Holset HX35 have the t25 flange, and will it fit the stock sr elbow?

[rb25drag]

I been hearing alot about this Hx35 turbo! I need someone to do a write up with pictures explaining the mods needed to make them work on our cars!

YES!!! I started this thread for that exact reason. post, and give it a bump.

As juding by what I know about the rb20, I plugged all my information into the squirrel calcualtor and the max you could get out of that turbo for it's efficency range of 21 psi is 332 whp. 332 whp is amazing for a 200 dollar turbo.

It can make 300whp at 19 psi. with fairly decent spool!
