Hello guys,

I am new to this board so any stupid questions will have to be forgiven. I currently have a red (automatic) 1990 300zx Twin Turbo with 57,000 miles. I would love to modify that car except two things are keeping me from doing it: I have no money left with the high car payment and insurance payment; and it's an automatic.

I bought my car in Iowa where I live and go to college BUT I am currently in Florida on an internship and could sell my car for much more in Florida than what I got it for in Iowa. I really love my car but I want to move on and experience another Nissan car. Since the Skyline is out of the question, I have decided to focus on the 1996 or 1997 240sx (SE or LE) with a silvia engine swap.

For those of you that know out there, what is the biggest difference between a 1996 and 1997 240sx?

I plan on trying to buy a high-mileage 5-speed 240 and getting it cheaper that way (which will be ok since I would replace virtually everything on the car.)

Assuming I have $15,000 and want to make my car a 12 second car-- or at least significantly faster than my 300zx, what modifications would I be able to afford? So far I have come up with two options and I would like the feedback on both.

OPTION ONE: I would put in a SR20DET engine in with an intake, exhaust, clutch, flywheel, and some other small mods. I would also have 18" wheels-- either SSR GT1, or Racing Hart/Axis. With the small amount of money left over I would try to put in a big brake kit-- perhaps project "mu."

What horsepower and 1/4 mile time would I be looking at here?

OPTION TWO: (My personal favorite!) I love the idea of having a "sleeper" car, so I would do away with the big wheels and have the exterior appear stock-- perhaps except for a carbon fiber hood painted the same color as the car and a big exhaust peeking out.... and also some cleared corner lights, etc. I would put in the perennial SR20DET engine with a bigger turbo and intercooler kit as well as the exhaust (which includes downpipes, no cats, etc.) and intake. I would further beef up the engine by adding stronger gears, headers, etc. I would also have a clutch and flywheel with maybe a short-throw shifter. Injectors would probably be needed too.

What kind of horsepower and 1/4 mile time would I be looking at here? Anyone have any examples? For both of these options, are they doable with $15,000? Keep in mind that money has to also include installation $$$. If you wish, come up with an option three which could combine #1 and #2... (but no body kits please!)... and realize I would like to be able to move past all of the jokers in the VR4's and Supras and into Corvette territory... (ZO6)... THANKS A LOT for your advice.

Probably gonna need more than 15000, since you dont already have the car. There is over 8000 dollars under the hood of my 89 hatch and that is with no internal mods to the sr, just bolt ons and stock turbo.

Sorry, the $15,000 is with the assumption that the 240sx is already bought and sitting in the garage... the $15,000 is solely for modifications. I also forgot to add my concerns about reliability on these modifided engines.

Well in that case 15,000 could swap the sr in easy. Go to heavythrottle.com and enjukuracing.com to check on the price for parts. As far as reliability they are just like every other engine if you take care of it it will take care of up.

Read this topic from our Archives section (SR Swap Info) (http://www.zilvia.net/f/showthread.php?s=&threadid=20680)


Welcome to the forum. Good luck with all your cars.

It seems the thread is taking on the focus of whether I would have enough money to swap in the SR20DET. I'm sorry. I am actually looking more for what items I should focus on in order to get my target time and hp (around 300 and up at wheels) and so forth. I fully realize the SR swap will be easy enough... but what else can I do to it? (Other than the given mods.) Are there any examples of cars running around which are twelve second cars on only $15,000 of modifications... links would be appreciated! Also, would upgrading to the bigger turbo and subsequent "must-have" modifications such as intercooler and injectors send the total cost out of my price range of $15,000. If I get all that stuff I would like to get it installed at once while the engine is out of the car before it all goes in..... Thanks.

I wouldn't count on $15,000. I'm currently in the process of buying a red 90' 300zxtt auto in Florida with 40k miles on it for less then $11,000

I like the sleeper idea.. :)


s13 sr20, add enjuku's turbo kit (you can customize to your liking with injectors and fuel etc.... your at 350-400 whp. Not saying you would have to go that route, but it is a direction.

then you can put on a set of 300zx brakes. no need for project mu.. the 300zx calipers are more than enough stopping power for the 240. Suspension, and various chassis bars like:

Coilovers
Sway bars
STB's
Poly subframe bushings and whatnot.

hell for 15,000 in mod money you could build an 11 second 240, or a SUPER track terror.. There is a guy on FreshAlloy.com that is running an SR into the 11's with MT Slicks with about 15,000 invested in the WHOLE car.. :) If I had 15k my car would be complete.
