Is a budget turbo build possible
I currently have an 89 carrera with 930 suspension and brakes, large front mount oil cooler and no engine. The car was previously powered by a 300 rwhp naturally aspirated race engine with stand alone engine management. The car wasn't streetable, and as such I hardly used it. I sold the race engine and bought a solid 964 3.6 core with intake manifolds and a stock ecu. I can't seem to motivate myself to put the car back together because I'm afraid it will be too boring to go back to stock. What would it take to go boosted on my 964 engine? I know it will take some money to get it running either way but I'd like to keep my future outlay close to 10k. Can i do anything with that budget, or would I be better to go as inexpensive as possible and try to enjoy the stock 3.6? Any advice is appreciated. I've even been mulling over another big NA build, but i don't think 10k will get me where I need to be. Also considered doing a v8 conversion but if that changed the cg height and ruined the driving character of the car, I would hate it.

It all depends what you will be using the car for. 10K is not a big budget. You might want to sell the 3.6 and use that $$$ as well. I would not go the V8 way but thats just my opinion its your car. As far as the cost on boosting your engine It might be better to try and find one done from a reputable source. Either way you already know you will be dropping $$$$.
|
Depends on the budget. I'd possibly consider horse trading up to a 3.3 engine ready to go. They're unbelievably simple and there is no mods needed to get it in. Plus they kick ass!!
|
Do you have to build the motor with that 10k? If not, it should be pretty easy to get a low boost turbo setup put together for less than that.
|
The engine should be ok. You obviously never know, but its supposed to be low miles and it had a good leak down. My educated guess is it will work for a while as is. Can 964 plastic manifolds be used, or will those have to go away? It seems like electromotive is fairly common for engine management. I haven't priced them at all. I know I won't be able to get into a motec, and I'm not sure I want to go mega squirt, hopefully there is something in between
|
Again, 930 engine needs no efi complication and costs. Cis is simple and effective to 350-400 easily.

I'm no fan of bastardizing a 911 with a V8 but if the car was never going to be anything more than a driver, and if my budget was on the conservative side I'd certainly give it a good hard look.
A modern, common, cheap-to-build GM V8 is considerably lighter than, for example, a 3.3 turbocharged engine and its CG is probably better as well, although I haven't specifically looked into that. If your 3.6 is solid - and you indicated it is - you could sell it and probably fund a 500hp build using a V8. Oh, and that ten-grand would still be burning a hole ... |
That's a pretty good point
|
Yes that is a good point but then again it all depends on how you see your car..Personally I would never do it but if that is something your willing to do it might fit the bill.
|
I think the 3.6 engine is 11.3/1 compression ratio from the factory, so I'm not sure how well that's going to work with forced induction. Seems too high even for a low pressure set up. Put stand alone EMS, ITBs, and a free flow exhaust and you can easily get 300+ NA hp out of that engine with no internal mods. Then lighten the crap out of car = big fun.
|
$10K buys you a running 930 engine. Swap them out and keep your 3.6 to preserve value. Sell the extra engine when you sell the car.
WIN-WIN. |

Whoops I thought the car was an '89 964. That's why I thought the 3.6 was stock.
Never mind ... |

My aim is to swap a 930 engine into my '78 Targa when rebuild time comes. Mothball the # matching piece and work some magic to fit intercoolers under a duck. |

Answer to the original question is NO.

Some DIY guesstimates:
1. Headers - $2k or less 2. eBay IC - $100-150 3. Turbo - $1k or less 4. ECU programming - $500+ 5. Couplings, aluminum IC piping, clamps, etc. - $500 6. TiAL F46 Wastegate - $500 7. Blow off valve - $300 or less? 8. Turbo headpipe and muffler - $500-1000? 9. Turbo tail - $??? Just throwing out some #'s, nothing comprehensive. |
I think you could build a nice 3.6L based turbo engine for $10K. One third of the expense will be lowering the C/R. More expensive bolt-ons can be swapped in later.

Jim2 supercharged a 3.6 in a non varioram 993. This could be a good option.
Pm him, I bet he would share what he has done. This you could do for under $10k. The issue with a 3.6 is the high compression so you cant run much boost - maybe 1/2 a bar at most. |
Yes
+1 This sounds good.

nothing to add here
besides cool screen name - howbout some pixzorz, jah? |
Uncle on here turbocharged his old 3.0L SC for something like two grand tops.. would be easy to do something similar for the 3.6, plus maybe lower the comp if absolutely necessary
|
If your 3.6 is in good shape, you can do it for 10k, if shopping smartly and doing some work yourself. You have forged pistons that can be milled to 8:1 compression, better heads, and more displacement then 3.3. Your manifold and even headers can be reused. Not ideal, but even RUF has done it. You will need EFI, injectors, intercooler, muffler , and some fabrication. That should give you 500hp on pump gas, with more torque down low. Much faster package for the street.
|
3.6 is a good base for a 3.3 8:5:1 CR engine.
Replace the 964 crank with a 3.0 crank, and you will have a great 3.3 engine since the 3.0 has shorter stroke Then you will have the cost for EFI. Fuel rails can be used, + some other stuff. New exhaust, turbo and tuning Could be a nice project |
I purchased this 1979 targa V8 conversion on casters and in boxes with a single draw through turbo. I do appreciate a true 911, but this was a fun build. My first twins

that thing must be an ANIMAL how about some more pics, and preferably - vids?! not my baaaag, baaaaby... but that's pretty forkin cool... |
I have seen numerous Turbo and twin turbo builds on 964 and 993 engines. Low boost will produce roughly 425hp possibly a bit more depending on engine with between .03 and .035 bar.
I have seen track builds with this setup last 20-30k miles if well maintained and many race engines I have seen last as long. $10k is tight it will get you a stage 1 but stage 2 would be preferable and closer to $12k or more. If you plan on tracking it a stage 2 is a must with a large IC and custom plumbing. I am currently building a track build the engine will be a 993 varioram engine with twin turbos and a massive IC. I know this engine will take a beating but it should last me 20k track miles probably more with proper care, cooling and stock internals. This car will not be street legal but you could get similar results with a street exhaust. Mine will look similar to this one. BTW these drive far better than the Factory Turbo cars. No lag to speak of and all the boost is up high so it basically just adds a lot of upper end power and torque giving it a very linear N/A feel. http://forums.pelicanparts.com/uploa...1421078669.jpg http://forums.pelicanparts.com/uploa...1421078685.jpg |
The "Killer Eggplant" was turbocharged and converted to programmable EFI for <$10k. Very basic turbo system, not the most elegant, but it still completely dominated the supercharged 3.6L that preceded it.
Make it a totally DIY job, labor & fabrication -- you might refresh the 3.6 and turbocharge it for that much. http://forums.pelicanparts.com/uploa...1421086275.jpg http://forums.pelicanparts.com/uploa...1421086397.jpg http://forums.pelicanparts.com/uploa...1421086412.jpg http://forums.pelicanparts.com/uploa...1421086425.jpg |
Here is a couple more pics of my V8 conversion, no video yet.
I am also torn between turbo or supercharging my Euro Row 85 TL Cab. Does anyone know if they offer a thicker head gasket to lower compression? I am going to pull the heads to have the valve guides done, and would like to prep it for boost. I am not interested in changing out pistons at this time. http://forums.pelicanparts.com/uploa...1421088471.jpg http://forums.pelicanparts.com/uploa...1421088505.jpg http://forums.pelicanparts.com/uploa...1421088582.jpg http://forums.pelicanparts.com/uploa...1421088695.jpg http://forums.pelicanparts.com/uploa...1421088736.jpg |
Donovan Aluminum Block is a great idea. Put that engine in a 914 !
