Engine Swaps



  • Hey, SO im getting a 1999 VW Golf GTI, and i was wondering what would be the max boost i should be running it at if i have the stock engine and stock Turbo, and i was also wondering how i would change my boost to something more higher... than the stock, also if i do turn up the boost what would be good to replace?

    Here's a system for you 545

    (I'm NOT recommending it because I never tried it!). It's a boost controller...and you'll want a better diverter valve for your stock turbo (or you'll dump boost too quickly) and a turbo timer to keep oil circulating in the turbo after you have shut down your engine. Figure $500 bucks or so plus installation costs if you aren't doing it yourself, and for that you get (claimed) 43 wheel horsepower!

    However, you should know that running a stock engine at higher boost than designed will shorten its life, depending on your discipline. You don't get something for nothing.

  • Allright, and ya im gonna do it myself, im a mechanic, but im just getting into some serious tunning, and im just trying to see if i should get that vw golf, like, i dont care really if it lasts me only like a year or even 2 b/c i just want this to have some fun, and when i blow it up i wanna have a serious engine ready with cam's lifter's, pistons, rods, bearings, turbo uprage, and just the whole deal, just i dont know how much it's gonna cost me and im think about 2,000 b/c im getting all the parts' and engine, From Europe, b/c i have someone over there, they are going to bring my engine Litterally in parts, every couple months when he comes back and fourth, so i know it's gonna be a hell of alot cheaper, and it's better from The germans... do you think it would be worth getting it from Europe, or should i just get one from here?

    Hi there, I was wondering what type of engine I could drop into my little 95 Nissan 200sx SE. The largest most aggressive engine possible :mad: for my FWD car :lemon: ahha thanks.

    Same choices as for the Altima a few posts up. You'd probably want the SR20DET, and you'll need a lot of SE-R parts (brackets, radiator, wiring harness, tranny).

    Want to do total engine swap on 83 Z28. Have 90 RS 305 TBI w/5spd trans. Want to put in 83 Z28. It has 350 auto. Need to know if I need to swap complete wire harnesses, etc. or if existing interior harness will plug up. Know I'll have to swap fuel tank, etc as is elec. fuel pump. Any ideas, info? Thanks,

    I'm currently going through a similar swap in a '95 Wrangler. Here's what will have to be changed: Engine(obviously), transmission, transfer case input shaft(or whole unit to one with the correct input shaft), engine wiring harness, computer, engine mounts will have to be moved(at least they do in the Wrangler), air box setup, radiator(maybe, it's the same part in the Wrangler), power steering pump(4 cylinder uses a remote reserve tank, I think, while the 6 uses an integrated one), starter, entire fuel delivery system(see comments below for explanation)....... I know I'm leaving things out. This is all I have considered on my swap. I haven't actually started my swap, but I am going through it looking at everything that is affected. I want to have all the parts together before I take the Wrangler apart.

    Be careful of the engine you buy. While you should consider its condition, try to buy a '92 to '95 model. I've been told there was a cylinder head design change in '92, making it more powerful than the '91 model. You can put an older engine in if you want to, but I wouldn't. Also, you can put a newer than '95 model year engine in. However a '96 on up will be an OBD-II engine, and while it can be plugged into an OBD-I computer(that's what you have), the fuel system will have to be replaced. OBD-I systems use a fuel pressure regulator mounted on the fuel rail, with an attached return line, and operate around 40 psi. OBD-II systems utilize a tank mounted pressure regulator, therefore no return line, and they operate at around 50 psi. Your current fuel pump may, or may not, be capable of running 50 psi for an extended time. Also, if you buy an OBD-II engine you'll probably want to run the OBD-II computer with it. It is very possible to integrate its wiring into your current harness, and I've read a few articles where it has been done, I started to do it as well. However, after diving into it, I've decided to go with an OBD-I setup.

    Swapping the motor and tranny in my son's 79 Malibu. The new tranny(TH350) mounts don't match up to the frame. He said the was a bracket attached to the old tranny that attached to the frame and also had a hanger for the catalytic converter but he didn't keep it. Does anyone know the name of this and where I can acquire a new one?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 58,510
    Probably called the rear transmission mount and probably a wrecking yard item.

    I've hit a couple of junk yards but as of yet haven't found one...
  • Hey all, I was wondering if i could swap my old 97 motor for the 2000-2003 neon motor? If is could would there be anything that needed to be changed? Or if it cant be dont why is that?

  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 58,510
    Once again the biggest challenge these days to swapping out older motors for newer ones is the engine management systems and getting all that to work in your 1997 car. At least with the much older cars when you swap you can often buy aftermarket EMS.

    Alright guys, I have a 2003 Jetta 2.0 that I bought for the sole purpose of turbocharging. I met a guy with a tuner shop that will perform all the necessary modifications and upgrades for $2,500. Great price, but after doing some research I like the idea of supercharged Jettas. Does anyone have any advice. I know it is going to be about $1,000 more but that is fairly trivial.
  • I rebuilding my 1987 Wrangler with a 1994 Grand Cherokee 4.0 HO engine.
    I had troubles with my computer. ( one of 1992 )
    Now I've got a correct computer from 1994 ( from a Wrangler ) with AX15 support.
    I have placed a wiring harnes from a 1994 Wrangler and it's patrol tank.

    Now my next move is to get the fuel pressure regulator working.
    Everything else seems to be oke.

    It's a good move to implement a Cherokee 4.0 HO engine.

    regards, :)
  • I just landed a computer and wiring harness for a 4.0L with AX-15 tranny out of a '95 Wrangler. I consider myself lucky that it's the same year harness as my Wrangler, this way I don't have to worry about the wiring harness plugging into the fuse block. Now if I can land an AX-15 at a reasonable price, I'll be in business! :D
  • I switched out the engine of my 1984 Wagoneer with a 1986 2.8 and I am having a real problem with the wiring none of the wire ends will match up the wiring has been changed before I got the Jeep the computer control is not on the 1984 but it is on the 1986 this simple engine switch is becoming a nightmare can I by pass the computer control since my 1984 does not have it the Haines manual I have is no help,I have asked a number of pro`s locally but they were more lost then I am,does anybody have any advice.? thanks for reading this countryc
  • Well, I must say that I know absolutely nothing about the engine/vehicle in question. Running on my experiences from other vehicles, which in this case may be worth a lot less than $0.02. If the '86 engine is not computer controlled, except for an O2 sensor, then you can bypass the computer. Is the ignition on the '86 computer controlled? Can the ignition from the '84 engine be swapped out?

    Can you give us more information about the engine?
  • Thanks for the reply the 1986 engine has a computer command control module and a four wire plug coming out of it that goes to the distributor and plugs in,there also a two wire plug coming out of the distributor that goes to the coil,the coil also has a second plug for a two wire plug that I am not sure were it is or were it goes. The 1986 Jeep was totaled out by the owner not me there was not much left other then the engine and tranny my Haynes repair book is not much help with this. I can fix anything when it comes to the mechanical repairs but the electrical repairs can give me gray hairs. The engine turns over but it is not getting the spark it needs to start,coil wire is plug into the distributor,I think my problem is the other two plug that the coil has on it my repair manual does not show it and it is for repairing 1984---2000 Jeep Wagoneer,Cherokee and Comanche maybe I should replace the distributor with one out of a 84 jeep or S10 they have the same engine.
  • If it's not getting any spark, then changing out the distributor with the one from the old engine would be my first move. Could that two wire plug coming from the coil be the 12V power supply?
  • :cry: I was just reading the post of another member who also blew their motor in the 1997 Jeep Grand Cherokee and was advised to get a used motor or a crate engine. I also just purchased the a 1997 Laredo with the V-8 and have no intentions of getting rid of it now. Other than the hunk of metal now sitting in the engine compartment, it's in perfect condition all around. Has all the toys on it too. So, I do not want to go for the used engine but would rather drop in a nice v-8 that is compatible. Can anyone recommend a few choices that won't require a whole new power train or massive engine compartment gutting to fit it in? I'm looking to up the HP to around 300 or 350 if possible from the stock 225 HP the 97 engine produced. I also figure I'll be dropping about 3500 to 4000 on an engine and no idea on labor and install yet. I was thinking it might have to be a chrysler but I have seen people use Chevy's in swaps. Since I am not a mechanic, looking at the specs myself is not going so well because I don't understand them to be honest. Any help at least on a few to look at would be fantastic. I don't want to simply rely on my mechanic to tell me everything without having a little knowledge of some options if possible.

    I'd be happy to reply with progress on what I encounter so other might learn from it as well.
  • whats up i'm in the same jam your in except i want the b18 motor swapp for my 91 civic hatchback
