is the any way i could turbo my stock sohc 4g64? has it been done? would it be possible ?
if it is that would be cool and easier than an engine swap for me

it has been done but if i was you i would swap a 2.0 turbo head on the 2.4 block

I agree on the head swap, believe me i've done some research and I have yet to find a sohc 2.4 8 valve turbo ed truck out there. They make turbo kits for eclipse/galant with the newer 2.4 but the manifold wont work. You could make or get someone to make a turbo manifold, it might be possible to use your stock manifold just it's right beside a motor mount and you may have to fabricate some things to get it to work. All and all if you have the money, i'm thinking at least a couple thousand, you could swap a 4g63 dohc head and turbo setup. That's assuming your bottom end is in good shape. Your not alone in the quest for boost in the sohc 4g64 and money makes or breaks you when modifying anything so good luck. Of course the dohc engine would be the best choice but if civics can be quick with a turbo 1.6 sohc, then whats the problem with a 2.4 light truck with a turbo?

I have to admit that the reason I bought my mighty max was to turbo it but soon i realised that the cost and random parts were hard to find so I decided to try a simpler route and go for a chevy 350 instead. 300 hp reliable and Carb.

Its not that I DONT like the idea but you really need a whole other car to even do the head swap with the harness and ecu and sensors.
This swap is rare and sorting out the wrong info can be hard i have read many forums that after 10 pages they still cand agree on timing this engine.
More power to you sir I wish it was an easy swap I would have done it.

It isnt thousands of dollars for a DOHC swap. Its actually simpler and people haven been doing this to their 64's for awhile now running 2G eclipse turbo ECUs on their DOHC's and even the SOHC 16v motors.

That being said the 2g eclipse and 3g 4g64's are a non distributor head set up. JDM 16v truck motors are available for $500 to $700 and anything 4g63 and 64 turbo parts will bolt on. You still need correct fuel support and tunning devices. But is an alternative to complete 4g63 motor swap. And us who have newer 2.4's need a tranny to go with it.

EDIT: Oh and there is a turbo 8v max. LSRMike. Thousands of dollars for his set up, and says he would do a different head set up if he was to do it again. Just something to think about.

No matter your choice it will be more than one thousand to get any swap up and running so thousands makes since when pricing the project, but oh yeah it would be kick ass with a 2.4 turbo DOHC . Whats wrong with the boost ready 3.0 V6 of the late 80's early nineties into our trucks, is it too much or hard to find parts.

I suppose it depends on where you get your parts. But either way your right, for a good set up at least 1 grand, unless you have parts laying around. I own a DSM so i allready am spoiled with o2 housing, turbo, and possibly manifold allready.

Dan I dont know much about the 3.0 v6. I love the light and easy to work on 4g's so I stick with them as my platform.

Here is a rundown for anyone interested in a stock to turbo set up:

1) either way youll need a different head for easy bolt on support.
DOHC from a 4g63 is the best bet. (but most costly)
SOHC from a galant or dont forget the late model 90's montero sports that have the 16v SOHC m/t.(important to note that this heads has the same ports as 2G eclipse sypers, 4g63 turbos, and 2.4 galants. oh and 3g eclipses)( all except for the montero sport head are igniton coil systems, not distributor's. There is a way to use a coil pack system but I wont go into it now.)

2) fuel
Bigger injectors at least 390's possibly 450's if you can. Use DSM parts, cheep and easy to find.
Fuel pump, stock eclipse turbo, or after market 190 is enough.
Adjustable regulator, or use a fuel rail from a dsm with their stock reg. (possible not sure though, its more of a theory that I plan on trying)

3) exhaust
Manifold stock turbo ones will bolt on to the above listed heads. And are only $50 -100. Aftermarket your looking at $120-1200.
Downpipe you will have to make yourself. I plan on using a stock dsm one and cutting and changing direction of the pipe after the bolt up point to the o2 housing.
O2 housing^ same as above use stock dsm or aftermarket. $120-500.

4) intake
The manifold is the biggest problem. My research shows that most commen is cutting and relocating the throttle body on opposite end. Me being interested in staying as close to stock as possible, am going to try and use the "over the head" montero sport SOHC 16v intake manifold.
And of course intake plumbing and an intercooler. Running from $100-500 respectivly.
5) tuning
Some sort of fuel controller and a way of watching ie: wideband o2 sensor or data logger or EGT gauge. And at the very least a boost gauge, and possible oil pressure for safty.
Safc's are anywhere from $100(used)-599 new.
Gauges are between $150(EGT and loggers) to $399 + for wideband o2 sensors, and $30 + for boost and oil pressure.

*(this is a basic set up for a do it yourself turbo kit. Since this seems to be a common question for our trucks, I hope this helps and at least puts some things in perspective of the basics in a turbo build. And remember on stock internals your looking for 5-8psi with a good tune to be safe.)*

You know what your doing and yes the 4G63 is a all around easy engine platform to modify and maintain since its been around for so long. I used to own 2 DSM a Talon non turbo 4g63 and Laser awd turbo, I wasnt inpressed with what little torque the Laser had, 10lbs of boost and sucked below 3800 rpm so I got rid of them and got what I new at the time, a 2000 Mustang gt. I got rid of the stang for something better on gas and family oriented but now I have a truck to play with. I like torque and that and the fact you can get 500+ hp out the V6 or so says dude in Japan is the only reason I considerd that engine. I've allways been more impressed with a boosted 4banger than a gas gussling v8.

Absolutly, the torque is lacking, and stock at 10psi....ya I wouldnt be impressed either compared to a 00 gt. Point is, sticking with what is allready in your truck is easier, and less costly in the long run then a motor swap. And with a v6 comes more weight, upgraded axels and driveshaft possibly. If you have a budget, I would suggest staying with the 2.4. But if you have the funds, then by all means swaparoo! Also if your ganna swap a 4g63t swap, with about $500-1k in upgraded parts can net you 250-300HP! Depending on tune and parts. And in out 2400lb trucks... Its alot of fun!

I grew up with SB chevys, and I am more fond of better mpg and comparable power with less weight. I can tell you though, 500+hp on stock internals (if possible) will take some money and the right parts. What is your goal exactly? Daily driver? Weekend warrior, something to spend time and money on for fun?

All engines spin in the same direction. They all spin clockwise. You are over thinking the motor. If anybody wants a 2.4 dohc turbo motor with more then enough power stock pick one up from a dodge SRT-4. Enough said.
