Turbo replacement options?


Recommended Posts

Hey ya'll, i was curious on what type of bolt on turbos there is for a 87 Conquest? Or is switching to a T3/t4 mount the best way to get a wider variety of aftermarket turbos that can be used? I have been looking at top end performances page and there wanting $1200-$1400 for a 14G turbo which is beyond rediculous but even there entry level T3/T4 kit is $1600... Is that the only options available? Parden my ignorance i am a Diesel Tech. and even a new stock turbo (thats twice the size) is $650 for my 7.3 so are these prices normal for these vehicles because of there rarity?

there are a few places that rebuild them and can bore them out to a larger size.

but a wider selection your better off going the T3-T4 mount.

 

the TD05H 18G or TD06 18G is my favorite turbo for these cars.

 

The Biggest bottle neck on these cars is the manifold to turbine opening. port it out.

here is a good link to show what i mean

I defiantly see what you mean warrior! that's defiantly going to be put on the to do list. UCW, for ebay turbo options a 14G is the only bolt on turbo? or is there other models that fit or can be made to fit easily? Not looking to make crazy power but with a fresh stock rebuilt motor and trans. I would like to step it up a bit.

Find a local turbo shop and take your stock turbo to them. Have them put an TD06 exhaust wheel in and either a 16g or 18g compressor wheel. For TBI that is a great all around turbo that works on stock or mildly modified cars.

BoostedStroker this reply isn't necessarily written for you, but to all of the new SQC members. You being a Diesel Tech know the below but there are new "kids" on this forum that may not. I think that I can say "kids" cuz I'm probably old enough to be a Grand Father to a good number of SQC'rs here. The only other SQC "Old Fart" on here that's older than me is Shelby that I'm aware of. Jeez - he's gonna give me some gas over that one. :lol:

 

Mitsu OEM fuel injection (EFI) computer fuel maps and distributors (and thereby factory rated HP & torque) differ widely between the years that the Starquests were made.

 

If you install a bigger turbo on a '87 or back you may not be taking full advantage of the bucks that you spent on the turbo cuz the those EFI computer fuel maps & distributor advance curves (vacuum advance, fly weights and their springs) can't FULLY support the increased air supply that a bigger turbo mod needs to achieve it's FULL potential.

 

For instance the:

'86 & '87 ESIR/TSI Intercooled Starquests were factory rated at 176 HP @ 5000 RPM; Torque 223 LB-FT @ 2500 RPM.

'88 & 89 ESIR/TSI Intercooled Starquests were factory rated at 188 HP @ 5000 RPM; Torque 234 LB_FT @ 2500 RPM.

 

The '88 & 89 Starquest models can support the increased demands of a larger turbo cuz the EFI ECU fuel maps for increased air flow and the distributor & it's vacuum advance were re-engineered to support up to about 350 HP using a modified Mitsu Starquest TB (which has been fully documented in the SQC Archives).

 

So it's not just bolting a bigger turbo on to make your Lady achieve all that it can be with JUST the turbo mod - there's a hellava lot more to consider to get the 'Most Punch for the Buck."

 

Also what condition is the rest of the drive train in to support the increased HP & TORQUE WITHOUT BREAKING SOME VERY EXPENSIVE PARTS?

 

I suggest that YOU SHOULD TAKE A LOOK AT THIS LINK TO SEE WHAT YOU MUST DO TO SUPPORT THE INCREASED HP/torque that you will subject your Lady's, at least 28 year old, probably poorly maintained by her previous owners, drive train to. ;)

Plus this link gives some easy to do mods which dramatically increase the pure stock OEM factory performance and

that will help you take full advantage of installing a bigger turbo. And it gives the '88 & '89 EFI ECU and distributor part nos.

 

Good Luck in your endeavor - BUT DO IT RIGHT from the start! ;) :) You and your Lady will be glad that you did. :)

Very well said! Lots of good information and pointers there. You cannot just bolt on a turbo and run more boost on a 30 year old car with knowing the condtion of motor and drivetrain also know the limitations! Do the supporting mods first! I do not add in my post, my conquest even though it is not pretty has 142k miles with a rebuilt motor with 15-20k miles (Good idea to run a compression test on any vehicle you are wanting to get more power out of so you KNOW that mechanically it is healthy or not) and the transmission is roughly a year and a half old. Even with that said if its your daily driver be realistic! If you damage your ride can you still get around? I may not know alot about these cars (Completly new to me!) but work as a Diesel tech have owned a few LT1 and LS1 camaros so i already know what i am getting into so if you dont do your RESEARCH and ask questions and dont think because you know how to change your oil your mechanically suited to change a turbo out. I have learned ALOT just by reading and going through these forums. I also have a 97 7.3 powerstroke that is much faster then my Conquest ;) so adding boost is not new to me. As for me i dont plan to make this a drag car, i am looking to make it a 300ish rwhp car that is daily driveable, i can have fun with and may be able to keep up with the truck :lol: After reading it seems like a 16G is best suited for my needs, seems like there is a few on ebay for cheap but require some minor modifactions? All the "Bolt on" 16g turbos are around $1200-$1400, i have a hard time spending that type of money when as said i can purchase a reman 7.3 turbo that is much bigger for $650 just seems pretty expensive... I have seen a couple videos of conquests running a ebay T70 turbo on youtube. What does it entail to mount a td05h 16g turbo on a conquest? I remember hearing something about reclocking the compressor housing and a few other details? As always i know you pay what you get for but i have heard good reviews for the ebay turbos from reputuable vendors as long as you dont plan on running auto x. Here is one turbo i was looking at http://www.ebay.com/itm/TD05-16G-7CM-TURBO-CHARGER-90-99-ECLIPSE-GST-GSX-TALON-TSI-4G63-DSM-FLANGE-350HP-/111430152813?hash=item19f1c1326d&vxp=mtr and here is the T70 i have seen a couple videos of on a few conquests on youtube (seems like theres a descent amount of lag with this size) http://www.ebay.com/itm/T70-TURBO-TURBOCHARGER-59-TRIM-7-A-R-COMPRESSOR-62-TURBINE-600-HP-BOOST-600-HP-/170766880859?fits=Make%3AChrysler|Model%3AConquest&hash=item27c27fd05b&vxp=mtr. Just looking for some input on which route to go, may not be purchasing one anytime soon if i decide to go with the more expensive route.

If I could ask a favor...... If you buy and install one of the eBay turbos will you either make a few install videos or take plenty of pics and post detail install with issues and solutions for anyone else considering on doing something similar? Performance gains would be great to and as always what you would have done different if you did it again. Thanks!!! And good luck

Your referring to the TD06 turbine wheel? Whats the specs on the sizing? So i can look for a T3 with roughly the same specs if i go that route. Will a 16g with a Td05h turbine wheel get me to where i want? As stated the goal is just a budget built 300rwhp DD, and from what i have been reading is very achievable with a healthy stock motor on the stock fuel system. As long as its a Td05 or Td05h it will bolt to the stock manifold? If i wanted a adapter i would need one that will bolt to a Td05 flange?

This motor NEEDS the 06 hotwheel, so whatever you go with, upgrading your turbine wheel is a must.

If ya'll have any links to turbos that you think would be a good opition please be free to post them up! Obviously it would be nice to buy the t3/t4 kit from racetep for $1800 but for me this is just a budget built DD as i spent that amount on the car itself... I dont mind spending 400-500 on a turbo and 100-200 on misc. parts but $800-$1200 for just a new turbo is a bit redicilous for what i am going to be doing with it. I think the problem is people buy the cheap turbos and go out and beat on them and expect them to last as long as a $800-$1200 name brand turbo which is defiantly not the case. If i can make it last for a year or two for $250-$300 i would be more then happy but then again i wouldnt be beating on it like a 16 year old :lol:

I would not go racetep at all.

Well if you want low budget.

Get an adapter

http://www.ebay.com/...3da6662&vxp=mtr

 

Then get a eBay t3 t4 turbo.

I think a gt2871 with 52 trim .63 A/R can get you to your goal.

http://www.ebay.com/...d9bff6e&vxp=mtr

 

This is like the adapter I run.

I also run a turbonetics

I think the ebay route is something im going to try, if i was auto-crossing it or drag racing it alot then obviously the cheaper turbo wouldnt last very long. For my sitution putting $500ish into a setup is reasonable for what ill be doing with it. That first adapter your listed is what would be needed to bolt to the stock manifold to use that gt2871 turbo? Or just look for a T3/T4 style turbo with roughly the same specs as that gt2871 turbo? What your recommend is probably what i will be purchasing :lol:
