Alright. So I am planning on boosting the Jeep this summer. I think it would definitely be fun and will make the Jeep different for sure. I was planning on going the supercharger route but the turbo I can do for way cheaper. I have been reading the past week about all kinds of stuff from people who have done it. I just have some questions from anyone that can help. I plan on using a turbo out of a Volvo as there are tons around me. The turbo would be a td04 mistubishi unit. As for the compressor housing I would have to see what I can find cause they range from a 13t to 19 I believe. The piping I can make so that's not a problem. I just need to know what type of controller people are using. I was looking at an aem fic and also their wideband kit and I think that would work but any input on this would be great. I also read that if I keep it at 5 psi I won't need a controller. But I don't know about that. I also need to know what injectors to use. I think people recommend #30 or 36 pd Ford ones. If anyone can help with anything that would be awesome. Thanks

If it's really so easy, how come no one is selling a nice all-in-one kit? If it's so easy, how bout you be that guy? I'd love to run a turbo, but I'm not about to mess with the nightmare R&D of getting it all laid-out and done right from scratch.

Im gonna try and be that guy. There a bunch of threads ive read where people have done it. It wont be for a couple of months because im gonna buy parts in stages but i want to have it done by the end of the summer maybe. I just need some guidance for anyone who has info about it

Banks sells a kit for 99-06 4.0 wranglers, that's as close as it gets currently. It's pretty damn close.

If you can be that guy, I'll be your friend.

Hoping to find a turbo this weekend, went this past one and scoped out atleast 6 volvos. Just gotta tear into them and see which one they have. I plan on rebuilding it and getting the wastegate to where i want it. After that I need to research the electronics more and hopefully come up with what I need. Im gonna try and keep this under or right around a 1000 but well see how that goes. AEM is probably what im gonna run, along with their wideband and boost gauge. Once i get the turbo im hoping i can mock up some pipes and then get everything in order and start crossing off my list

For what both systems cost in the end you could almost v8 swap and have a lot more power.And if you go a ls1 or something all aluminum and lose 200lbs.

I wanted to boost mine a while back. I actually sourced most of the parts fairly cheap. Supercharger, piping and the small stuff but the real issue is that in order to provide proper fuel during boost, I needed to buy this $600 tuner that runs a 7th injector.

Can you weld? This manifold cost roughly $80 to make. Sch40 mild steel from a scrap yard sold at $2 a pound and eBay sourced flanges for the t3 and external wastegate option. The turbo is a holset h1c off of a 5.9 Cummins generator. I bought it for $50 because the seller thought it was blown. They all leak oil into the turbine after a while. Another $50 into it to rebuild and upgrade the thrust bearing and the turbine oil seal.
Manifold $80
Turbo $100



I picked up my 1913 FIC from modernperformance. $390

36lbs ev1 injectors $100 for 8

Used wastegate for $80

AEM Wideband o2 sensor. $160 It doesn't not matter if you run 5psi or 30 psi a wideband is a must. A tuning device is necessary at any level of above atmosphere performance.

Down pipe was made from an "S" bend what a v band flange from eBay. $50?

Optional custom extension harness for $60

Charge Piping and couplers 180?

Fittings turbo feed and drain with bulkhead $80?

Anything with a ? Mark I have forgotten exactly what I paid and is a close estimate.

When choosing a turbo best bet is to ask yourself what power goal you want to make and how much air you need to make that goal. Then find the turbos you have available to you and look up their individual flow maps. 5 psi from one turbo can be wildly different from another.

If you are actually serious about starting this project my advice is to buy what ever tuning device you want and wire it in while the truck is N/A. That way you get an idea of the learning curve you are entering.

Finally, when a turbo manifold comes on the market that is below $300 I see slot more people that will be interested in turbo jeep.

Hemicuda - I like your idea, just dont use the TD04 turbo. It is way too small. 2 of them would probably work good though! Something like a Garrett GT30 would be a better size and has many housings to choose from. I would also stay away from any factory diesel turbo. They are designed to run a lot higher boost then what you want and will not be the most efficient thing at a low boost.

See I love the 4.0 which is why im keeping it. also an engine swap isnt really what i want. I want a mainly bolt on system, with the minor exceptions.

I am going to run a remote system, having the turbo located where the airbox is now. My problem is i have a 2000 with those ****ty pre cats and since this will be my DD i need to keep it so it can pass NY inspection. Im gonna u pipe it from the from the bottom up to the turbo.

My problem with the turbo is that I am junkyard sourcing it so I am kind of limited to what is available. The yards around me are full of volvos, really the only turbo cars there. is the td04 really to small even if i am only running 6psi max? also what did the garret come on? maybe id get lucky finding one. any other types you know of that could work better?

Cummins93

Shoot. I'd better call all the DSM guys running hx35s/hx40s and tell them they gotta take them off cause it's a diesel turbo...


Tdo4 is only a sizing of exhaust housings. Compressor flow maps help size the correct compressor. That is where you start. Then figure out what exhaust housing options are available. If we want to use the Mitsubishi sizing you will find the 15g 16g 20g s20g and so on. Holset is the hx30 35 40 50. Or we can classify them universally using mm of the inducer.

Again find a turbo you think you would like to use and provide the numbers on the compressor housing badge. Also please state your power goals and use of this vehicle. Pictures help.

There is nothing wrong with running a diesel turbo as long as the boost you are running is in the efficient range of that turbo. Running a turbo designed for 30 psi boost at 7 psi will work yes. But you can get a better setup with a turbo designed to run at low boost. Most diesel turbos have the wrong sized housings for a gasoline engine. Changing the housing is more like fine tuning what you already have. Still not the best idea. Like you said, look at flow maps first. BTW - most people dont know how to read flow maps.

Yes I would prefer to go off of inducer and exducer sizes along with the housing sizes. Makes things less complicated in my opinion.

I would love to find a holset turbo, but ive searched 3 yards already and nothing but volvos, audi, vw for turbo set ups. other than the td04, are there other turbos out there i could use.

even though the tdo4 is smaller, would it still work? im only making 5 to 6 psi max. My aim is for 200 at the wheels. I would probably look around and see which ones i could scavange like a 13g 15t 16 etc. I wanna know if a td04 would work. or what else i could be looking for.

5-Speed

Yes it will work. No it wont be the best choice. 200 at the wheels probably wont happen either. My suggestion is do some research on the turbo cars they have there. The closer to a 4.0L engine you can find, the closer that turbo will be matched. There is always the option of a China turbo on Ebay. You can find them cheap and in the right size.
