does anyone know engine internal diff to put a lpt from 98 s 70 on a 96 2.4 na what i need to know is piston rods cumbustion chamber size that is diff from s70 motor. if you want to post to sell my na for a turbo please dont post i like to experiment on motors and if you have nuthin good or helpful to say please dont say but any helpful insight is much appreciated
thanks

I believe the head/block design is different between the 2.4NA and 2.4LPT.

The 2.3, at least, has enlarged cooling jackets and sodium-filled valves to deal with the excess heat from all the air being forced into the engine. The 2.4T has the sodium filled valves.

Making the swap would require doing extra plumbing for the oil and coolant lines for the turbo and a new radiator with an oil cooler.

What you could do, if you really wanted to, is get your hands on a donor T5 car (94-98) and then get your hands on a '96 or '97 T5 ECU.

You may not want to hear it, but turboing a non-turbo engine when a direct-fit turbo engine is available is just plain stupid.

To turbo that engine you would need at minimum;
Frst number is used/cheap aftermarket, 2nd is OEM or High End i.e. IPD

Turbo: $300-$2400 depending on how crazy you're trying to go
Exhaust manifold: $75-500+
Intake manifold: $75-500+
GLT/T5 ecu:$150-300
Injectors: $250-800
S70/T5 radiator: $115-300
Turbo oil lines: $50-200
Turbo coolant line: $50-200
Spark plugs: $10-50
Plug wires:$50-100
Downpipe: $200-700
O2 sensors: $50-200
TCV: $50-85
Vacuum lines: $20-100
Intercooler:$75-500+
Intercooler hoses and pipes: $75-200+

I'm sure I'm missing some parts, but that's well over $1500.
You can find a complete T5 engine, ecu, turbo, harness and tranny for less.
Unless you have an exceptionally clean and straight body and interior on your Nonturbo, you would really be much better off selling it and getting a GLT or T5.

I'm sure I'm missing a few expenses as well

Its really an excersise in futility. On top of whats posted above the 2.4NA runs 10.5:1 and the LPT runs 9:1. Turbo running on typical road gas at that CR is going to be shoddy. Its your money though!

The 2.3's have beefier rods to cope with the extra loads they are engineered with high (specific) output in mind. In passing ive seen people that have turboed the 2.4NA to any decent amount bending rods.

im going to get a lpt and see what i can do i have a few spare parts from another motor that i have and i am going to go to get some other parts i may need but i will take into consideration findin out how diff the two motors are as far as head and block i appreciate the info guys but i do have a question. how is it that you came up with 1500. plus for parts i turbo a couple of honda motors for way way less than that and if you look around enough you may find that you dont need 1500. to turbo a motor i will say that i have to strengten the bottom end but it is plausible withe the right stuff. i think i will persue it a little more because if all you do is guestimate you will never know what can be done

Its probably more about economies of scale. Theres more hondas out there than Volvos and more people who want to turbo them. More choice and more competition. If you can shoehorn cheaper honda stuff in there great. I still dont know why you would spend your time on a motor thats not a good base for tuning, but its your time and money. I get what you are saying about experimentation, but sometimes its not worth the effort IMO. Theres a lot to be said for getting a 2.3 T5 and modding the $hit out of that instead. Chip alone can put you in 300BHP territory....

blackburn how good are the internals in the motor good for whp. i think in my opinion is trying it out to see which piston will go first it aint fun if ya aint gettin dirty. what maods are you doin to a already turbo motor chip, intake , exhaust, id rather spend money and change pistons rods get a full port and polish and some other internal parts than just buy a turbo motor and put it in its better if ya build it than buy it

has anybody ever tried to build an na motor to get boosted or does everybody just quote other people that think of it nad then kill the idea without trying thanks blackburn for the info ill look into the other motor and see what i gather from that

Go ahead, turbo it, build the block, run 15psi and still be a 14.5+ second car.

People aren't telling you it's a bad idea because they're haters, they're telling you its a bad idea because ITS A BAD IDEA.

Cruise around volvospeed, and look at the mod lists on some of the T5s.
Those guys have invested thousands in parts, and countless hours of tuning and tweaking and aren't evening breaking 13.5 in the 1/4 .

What is your goal?

I'm all about turbo cars and trucks, but some are better platforms than others, and a heavy, FWD car, with a high compression engine, is about the poorest platform to start out with.

The connecting rods in the NA engines are very weak - that should be your starting point if you want to go ahead with it. Then new valves. Cooling would still be a concern if you're running high amounts of boost though; aluminum engines/heads don't take kindly to large amounts of heat. Other than that, I don't know the differences between the 2.4T and 2.4 - I have a 2.3.
