fitting a small block chevy into an S13 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

FloridaRacing · 12-18-2008, 11:43 PM

My thread got locked before because it was simply a list of parts, well now those list of parts have made their way to a form of a completed engine that is a traditional 400 CI small block Chevy. It has been on the engine dyno and has made 702 HP and 684 FT/TQ. I have been working with Mckinney Motorsports on sourcing parts to make a first mount kit work for these engines.

Small block Chevys are cheap, easy to find, and hopefully after this, give people a cheaper alternative to an LS based engine. Best part of all, it is carbbed and requires minimal wiring.

This isnt the engine, rather than a mock up. Mounts are prototypes and are pretty close to done. The oil pan is a front sump type that has been modified to fit between the sway bar and sub frame without any modifications. The header type is equal length and will only require minimal drivers side adjustment to fit. Transmission is a TKO 600, which is shorter then a traditional 5 speed. A Traditional one will fit further back and correctly in the hole, which they are also building mounts for off this engine. Here is the initial mock up of these mounts on the test engine.

Headers look fucking crazy...that shit gonna have enough room to clear the steering shaft???

420sx · 12-19-2008, 12:42 AM

why so crazy with the headers? and you should have pushed the motor further, the shifter is way far in.

i had no problem fitting the ls1 into my s14, using my mounts of course.

*kingkilburn* · 12-19-2008, 02:32 AM

I assume this is a "track only" swap. I don't see how you are going to get a carbed motor past a ref.

Cool swap though.

we forgot about that....

"Best part of all, it is carbbed and requires minimal wiring."

I really wouldn't say that is the best part of all. I'd say it is the cheapest part of all. hehehe

g6civcx · 12-19-2008, 07:10 AM

I think I am the only person on here with this swap. My comments for you:

* Good job on height placement. I think your engine may actually be lower than mine. My biggest gripe with a lot of kits is that they place the engine way too high.

* Why didn't you cut out the firewall and shove the motor as further back as you possibly can? It will give better weight distribution as well as allowing you to shorten the propeller shaft as well.

* I used block hugger headers. Probably doesn't make as much top end as your headers but they're cheap and they fit.

If you have any specific questions please feel free to let me know. I'll do what I can based on my experience with this swap.

Good to see the small block getting some love. Good luck.

FloridaRacing · 12-19-2008, 09:33 AM

The headers will fit just fine, they passenger side works great and the driver side just needs a pie cut and shift on the 3 bolt flange, thats it. Also they are equal length with 1 7/8s primaries. Believe it or not, these are off the shelf headers from Hooker.

As I stated above, this transmission is based of a muncie 4 speed and is shorter then a traditional 5- 6 speed, which will fit fully centered on those applications.

The idea behind this swap was to make it as easy as possible for people to recreate with the mount kit, and also this is a street car, I didnt want to cut the firewall and shove the motor back into the dash.

ROUGE180 · 12-19-2008, 09:40 AM

I can't wait to see the progress especially with the traditional type trans. So ball park, how much would a swap like this cost turn key assuming that I did all the labor? Nothing crazy, no upgrades, just in the car mounted and ready to drive.

Thats vague, it all depends on how much you want to spend on a motor, theres everything from brand new stock GM 350s, strokers, to used engines.

You could find a running 4 speed with a 350 for probably $1000-$1500, plus mounts, oil pan, oil pump pickup. Theres no pricing yet on the swap parts, but probably mounted and running for around $3k

wow-thats-a-cool-car · 12-19-2008, 11:54 AM

there doesn't look like theres room for like anything important. Like the break booster and windshield wiper motor and like all the steering stuff. But I can't wait to see it done, so hurry up and finish it lol

Theres plenty of room for all that stuff, one of the header tubes MAY have to be modified for brake booster.

How does the distributor fit?

Note the large cutout in the firewall above the rear of the motor.

VQMaxFan · 12-19-2008, 01:02 PM

What happens when you want to change your spark plugs? It looks nearly impossible with those headers.

no, thats from something else, this is just a mockup engine bay.

The distributor fits fine, HEI types are a little too big, but no one runs them anyway

spark plugs are super easy to get to

trsilvias13 · 12-19-2008, 02:07 PM

I read somewhere that some guy figured out how to drop one a sbc motor into a s13 using engine mounts from a van - it was direct drop in and no need to weld anything or something close to a bolt in, no welded type build. It wasn't on silviav8.com, but I think it was link from there to maybe Nico. But I remember seeing it somewhere.

FloridaRacing · 12-19-2008, 02:23 PM

Ill have to check it out, but this mount kit puts the engine in the right spot

FloridaRacing · 12-19-2008, 04:22 PM

modified pan, making a front sump pickup work on a rear sump oil pump, engine waiting for final mockup

Flicktitty · 12-19-2008, 04:55 PM

what the fuck is done to that small block to make 700HP? On motor or Nitrous?

RUTH'LESSDET · 12-19-2008, 05:18 PM

2008 is the year of the import v8....I love it!!!!

yep, 523 on motor, 702 on nitrous, only 10:1 compression, makes power to 6400, probably a 7000 RPM limiter. Makes 418 FT/TQ by 2500 RPM

sillyvia13 · 12-19-2008, 05:57 PM

thats a ghey engine throw it away....
waits out back for trash to fly....

HOLY! SHIT!
CAN YOU PLEASE PLEASE PLEASE make a video of mean burnouts! PLEASE! and side cut exh so flames can be seen by driver aand passenger...

FUCK YES!
so badass.

FloridaRacing · 12-19-2008, 06:09 PM

If not HEI, then what are you running?

Correct. They're much easier to get to than an LS1 in an fbody.

Nice, Mind PMing me the spec's on the motor (cam,rotating assembly,etc)

My buddy has a 72 Chevelle with a 496 BBC car motor made 732HP on motor.

xs240 · 12-20-2008, 08:23 AM

damn.. no replacment for displacement. This car will be mad. Question.... what is it's purpose?
