View Full Version : Twin Turbo or Stage 3 Upgrade On PRV

Hi guys, I have been wondering whether or not I want to swap the engine out of my delorean or rather just build on the PRV. My question is if I was going to keep the original engine and strive for the most power I could, would it be more intelligent to get the stage 3 upgrade or to install a twin turbo. Kind of a second question on top of the first, which would be the best twin turbo, the Island or another aftermarket one.

Ps. I already have the eibach suspension, at what amount of power would I need to replace the tranny and any other parts that would be affected by the increase in power.


Thanks, and I apologize for my lack of knowledge on certain aspects as I am learning as I go.

Good question, I am wondering the same too

Out of all the replies you will get 33.3 % will say, “It’s not worth the money and hassle for so little gain.” 33.3% will say, “Go for the twin Turbo.” 33.3% will say, “Go for the Supercharger.”

Oh, and you asked, “What about an engine swap?”

With out describing how are you going to accomplish the above then it’s really hard to recommend the best solution for you.
Here is a quote I have heard many times. “Speed cost money. How fast do you want to go?”

I’m not an auto mechanic so my knowledge is limited. However, DMC Northwest in Bellevue, Washington installed the first customer paid Sprintex supercharger on a DeLorean PRV. It’s a very new beast and it will take some time to see how well it operates in a daily driver. Our old DeLoreans do not requre any emmissions testing here in Washington state so if there is a future problem it may never be realized since you can keep driving your old car and not have a clue whether the air / fuel mixture and timing are correct.

Thread about the supercharged D.
http://dmctalk.org/showthread.php?2130-Stage-III-Supercharger-Upgrade-Thread

There are no twin turbo DeLoreans that I know of here in the Pacific Northwest DeLorean Club so I don’t know what they are like to operate and maintian. There are two DeLoreans that have a single turbo that I have seen for myself. Any modification to the orginal powerplant or swap is going to be big money and big headaches.

I would love to do what you are asking if I only had the money. I just don’t care for the increased resonance (noise) of these more powerful engines and free-er flowing exhaust systems.

To give you all an idea, I'm looking to spend about 10k on the engine when it's all set and done. If that's not enough feel free to tell me. I'm not unrealistic just not well educated on the subject.

Just so I have an idea, how "little is the gain of the turbo. And how does it compare to a stage 3

This is just me, but I would do a Stage 2 by DMC or a Spec 2 offered by DPI Josh. I have a friend with the Island Twin Turbo kit. It works quite well, but puts out about the same amount as a Stage 2. He did his add on way before the Stage 2 was offered.

I like this suggestion, the only issue i see is, don't I have to send the delorean in to a dmc shop. Like I said I'm in mass and to ship the car back and forth to Florida is kind of a headache. If i can get the island twin turbo and have it installed it might be less of a headache. Is there any real down side to the turbo other then it's output? I know somewhere on the fourm I saw someone with a twin turbo along with other mods at about 270 HP. I'm not saying I want to go this extreme but does any one know how much he spent on all that?

Thanks

What kind of power/gains does each spec produce? Is spec III still the 2.8 block?

Anything after SPEC II is a different 3.0 bottom end with forged internals. If you are going to produce power the a beefed up bottom end is extremely important. The only reason why others bolt superchargers onto NA upgraded platforms is because the pressure is very low and the camshafts are very mild.

Thank You. I'm probably only going to be modifying the engine after the summer but I have bookmarked yourwebsite and there is a good chance I will be making a purchase in the future.

I have one of (the?) first Spec 2 parts for home install kit. Its a lot of work to install (you are pulling the heads and entire exhaust, after all), but I am very happy with the results. A stock car can't even begin to compare.

Are these numbers from the wheels or the crank. These seem awfully high for a naturally aspirated DeLorean.

I have a the bae turbo and twin island turbo. Both are quite a bit faster then my stock deloreans. Both can be a bolt on kit but if you want to run more then 5-6 lbs you should have the motor built to handle the boost. Both mine were done buy the previous owners. So as price I can not tell you but well worth doing. The twin turbo is two small turbos with little lag. The bae is one turbo with some lag time. There is not a huge difference between the two.

Got ya. Still pretty darn impressive! Well... except for that 130 stock, haha.

Josh, what about the bhp for the spec 1 with the cat delete pipe? That's the setup I've got my eyes on for when I'm done redoing my a/c.

I will have accurate numbers shortly. Currently everything is calculated from rwhp. As I just invested in an engine dyno for test firing and certifying each build we send out the door.

So I sit here corrected. I did not know of anyone (until now) in the PNDC who owns a twin turbo D. I’ve never met him so I hope one day he will bring them out to a club function. And, on top of that I had no idea anyone owns more than two DeLoreans at the same time.

Josh's 3.0 build will be the last "one off" system we produce. Mainly because everyone that sees it wants one too. This is fine but it is extremely time consuming to do it right. Being a perfectionist makes it even worse. After this everything for owners will be manufactured in quantity by SW. Aka our twin turbo system a few of you have had a chance to enjoy so far. For warranty reasons module replaceable components is important. As much as I like spending weeks building custom kits, it just doesn't make sense from a business standpoint. I learned early on these were very demanding to produce and have always kept quite only elaborating when asked.



I had already sworn off these custom builds when Josh contacted me last year. He was dealing with the common issue of a rotting cooling system on his 3.0 crate motor swap. I was set back by everything he had figured out for himself on the install, EFI etc and decided this would be a great last one off project to take the rest of the way.

Here is a picture from a while back. Everything is out at Jet Hot right now being coated. (IE turbine housing, all exhaust components etc.) Don't mind the ugly AC compressor. There for mock up use only.
Planning on having this one up and running at the start of June.

I will really struggle tuning this thing in under 300bhp. PRV's love boost but this must be a reliable daily driver in Az with high ambient temperatures to begin with. Also switched to EDIS and Josh installed meth injection prior to dropping it off.

Sorry guys i hate to grave dig but I didn't want to start a new thread for the same question.

When you say anything after spec II is 3.0, does that mean a new engine or is it a 3.0 conversion kit for the prv.

Thanks

Anything above a SPEC II platform utilizes a 3.0 even fire bottom end with EDIS spark control. Basically anything above SPEC II is a completely different engine package.

It sure is. I am in love with that intake manifold and serpentine belt. Now that I have a garage, I am tempted to start shopping for a 3.0L. Can't afford yours, but may end up buying some parts from you. Or I will win the lottery and send you my car to build into a beast. I can hope, right? :-)
