5-10-2015 - Now it has been even longer. I am on my last engine
choice. The BMW V10 would have been nice, but the cost and
complexity of it just was not there. I have now decided on going
with a 1uzfe Toyota/Lexus V8 and will twin turbo it in different
Stage I - stock block and not opened up with 7-10psi for about
400-500rwhp. I will make a custom intake manifold, single 92MM
TB, 1000cc injectors, MS3 Pro ECU. T3/T4 T04E .48ar 50 trim
turbos with custom exhaust manifold. These should be good for
300hp each and spool up nice.
Stage II - same with a dry sump setup. I will use a 4 stage
external dry sump pump, custom oil pan, peterson dry sump tank,
ATI balancer and gilmer gears. It will have plenty of oil
pressure and be able to go to 10,000+ when I want.
Stage III- I will add custom cams, valve springs, shimless buckets,
port and polish, Forged con rods, Forged pistons 9.5 c/r, ARP
studs. This will be good for 20psi of boost if I ever want to go
there. Once this is done I will do 12-15psi and rev to 9000-9500
rpm. I am thinking it will be in the 600rwhp+ range.
Stage IV - All the above, but Borg Wagner EFR turbos. These will
spool up super fast and have a higher overall output if I want
to go there.
I currently have most of the turbo items and I am mocking up the
engine items now. I should have the custom flywheel in my hands
to start bolting things together. Exciting times to come for
6-5-14- I know it is has been forever, but we put this on
the hold for a minute to go racing and finish up other projects.
We will be back on it shortly. We have made a bunch of changes
and now will be using a BMW S85 V10 engine. Yes, 8500rpm, 550 hp
and V10 will go very well with this car. We also are going with
a full sequential transaxle from Quafe with LSD and this will
match up very well. We are hoping to get back on this late
Welcome to the Superlite SL-C build blog. I have purchased an
SLC from Superlite Cars. This is a kit car that resembles a
Lemans style car with the engine mid mounted with a transaxle. I
have always loved the look of the Lemans car and this fits what
I really like. I kit is very well done, comes with most items
that are needed and a rolling chassis kit from the factory.
I will be updating my thoughts and build process here.
7-28-12- Stereo in the car. There is not a great location for a
head unit for the car. I did some research and found that you
can get a detachable face radio and mount that face in other
places so the radio does not have to go all the way in the way
when there is not enough room. You need to solder in a connector
wire to make it work, but that has been a lot by others and
figured out. I plan to get a JVC dual din size head unit with a
5 channel output. I will get a set of 6.5" speakers and mount in
the dash, a 6x9 for the doors and a 10" sub. Then get a 5
channel amp and have a killer sound system.
7-27-12- I have been pondering the twin turbo setup. I need to
make a custom intake manifold for this as the 3mz intake is
plastic. I was looking at the Nissan GTR, which makes like
500-700hp easy and will do a similar intake to what they have.
It will be a dual plenum intake with dual throttle bodies. This
will be the best for fitment purposes to clear the engine lid,
give the shortest path for the tubos for plumbing and should
work out really well to make high hp. The only issue is to
balance out the throttle bodies and I have a few ideas to make
7-25-12- There is another SLC owner that is about an hour away
from me up in northern VA. I went and saw his car before I
ordered mine. I am going to go back up there and take some
measurements for items to do ahead of time. I need to figure out
lengths on fuel hoses, size and configuration of the surge tank
I want to build. I have to think about where to put things
because I will have the twin turbos, hoses, intercoolers and
other things to think about for later.
7-22-12- I have been pondering the pedals and making them move
forward and back. I am going to mount the seat solid to the
floor so it can be about 2" lower for head room. The steering
wheel comes stock with tilt and telescopic so that is great. I
plan to make the pedals go back and forth with a 12 volt linear
actuator that can do about 450lbs of force. This will move the
pedals forward and back as needed. I just will need to make some
sliding brackets or something when it comes. I have some ideas
in my head and will figure it out later when the car comes to
me. The C6 steering rack also came with an extra switch on the
column so I will use that basic location so it does not clutter
up the dash.
7-20-12- The SLC comes with fiberglass bucket seats that are not
covered. They are ok, but not that comfortable for a lot of
street use. I got a set of Cipher seats off ebay for $329
shipped for the set. These are one of the few seats that will
fit in the SLC. When I got them they actually seem really nice.
I was worried at the lower price it might not work out that
well, but it sure did. Now I can drive the car everyday to work
in more comfort. I will keep the SLC bucket seats and swap them
back in if I ever do a track day with the car.
7-15-12- I ordered the fuel pumps. This will have a 18 gallon
tank that will feed a surge tank so two pumps are needed. I
might change my mind later and get the LS376 engine so I am
making sure the pumps and lines I get are good enough for both
engines. I got the Bosch 044 external pump for the fuel rails
after the surge tank. I also got the Holley 125 feed pump from
the tank to the surge tank. These will have all 8an lines so it
should be able to handle all the hp I can throw at it. I also
got two in line fuel filters. I just need to figure out just
what fittings and hose lengths I will need to get the car.
7-12-12- I spent the morning getting heat exhaustion with a
buddy at the pick a park. We got all the parts needed for the
ecu, engine harness, alternator, TB, ect. It was 104 degrees out
and we got dehydrated quick outside. Not fun, but we got what we
needed. The cost was $250 for everything needed. So the engine,
harness and ecu with other items comes to $750. So not bad at
all. I can also sell some items off the 3mz I got, such as the
tb and other items to get some money back.
7-10-12- I got a stock C6 Corvette steering wheel with controls
and the entire steering colum from a wrecked car. This is a
great find and only cost me $125. So I need to make a new center
section and will do that myself as the air bag was blown, but
the main thing needed are the steering wheel controls with all
the connectors inside. I plan to use the buttons in the center
section for the raidio to change channel, mode and volume. I got
an automatic steering wheel with paddle shifting. I will use the
shift up button to change my boost level from like, 8 to 10 psi
and then the pull back to scramble boost to 12psi. So I can
adjust boost on the fly with steering wheel controls. I think
that will come out really cool when done.
7-5-12- I found my engine, actually two of them. I am going to
use a V6 in my build. Now most use a LSX series of engines and
the engine of choice is the LS376 with 480hp. I do like that
engine myself, but the cost with the engine, ecu and pedal with
shipping will run in the $8000+ range. I decided to go with an
engine from a 2005 Toyota Sienna, or known as the 3MZ-Fe engine.
This makes about 250hp. Not much in stock form when normally
aspirated, but I do plan to twin turbo the engine. So it will be
similar in size and power of a Porsche 911 twin turbo, but the
car will weight over 1,000 lbs less. I got two 3mz engines, one
will be for NA and the other I will build up for the twin turbo
later once the car is running and sorted out. The cost was only
$800 for both, or $500 for the single engine. Now I do plan on
using a 1995 Toyota Camry wiring harness, ecu, alternator, coils
and throttle body. So I am doing a hybrid setup for the engine
called a 1mz/3mz hybrid. I am using the older electronics
because it is easier to control and I will also add a Greddy
emanage piggy back computer to adjust fuel and spark later when
we go twin turbo. I plan to have a few stages of twin turbo. I
will use a stock engine unopened with 8psi, 10 psi and 12psi.
With this setup we should have about 450 hp. Later we will add
forged lower compression pistons and have 15psi and 18psi. That
setup should have 550hp.
Now another benefit to the V6 versus the V8 is that the 3mz is a
very compact engine. So we can mount the engine and transaxle
farther forward in the chassis by about 4-7". The engine is all
aluminum so it weights in about 75-100lbs lighter than a V8. The
engine can also be mounted a few inches lower. This should all
add up to a better handling car when done and a lighter car. The
turbos will add some weight, but they are small turbos as I just
need to use t3/t4 turbos since are are using two. I plan to also
have twin intercoolers, methanol injection and large 600cc
7-3-12- I got a set of factory Corvette Grand Sport wheels off
ebay for $400. I really like the 5 spoke design on these and
being factory wheels they are light and strong. The sizes are
18x9.5 front adn 19x12 rear. Weight is 21 and 24 lbs, which is
not bad for the sizes I got. I made a spreadsheet of tires to
get and I am trying to decide now. I plan to use 265x35x18 front
and 305x30x19 rear. My main choices on tires the Hankook V12 or
RS3. The RS3 seems to be much nicer, but cost is about $600 more
for the set new, so we will see.
7-2-2012- Fran called and let me know he found a really good
deal on a transaxle. I wanted to get a Porsche 997 transaxle as
that should be the strongest out there, have 6 speeds and LSD.
The only issue was this transaxle setup would cost $14,000. Now
I could not afford that much money and if the transaxle would be
that much I would not be able to afford the car. I am on a tight
budget here. Fran found me everything I was looking for and
strong enough to handle what I will throw at it. It is a G50/20
6speed LSD transaxle from a 1998 Porsche carrera 2. This will do
what I need and cost $4500 with the clutch, pressure plate,
disc, throw out bearing, fork and slave cylinder. I will need to
get a custom flywheel made up to mate the engine from Kennedy.
So transaxle found and done so that is great.
7-1-2012- Kit ordered. I ordered the kit in white gelcoat. The
gelcoat is supposed to be so good that it just needs to be wet
sanded and buffed for a great finish. White looks great and
should hide small blemishes if there are any. I also ordered the
lift kit, which will raise the front end about 3" or so to get
over speed bumps and certain driveways. I plan to use it on a
street a lot so this was needed. I ordered the interior in
carbon fiber. I like the look of carbon fiber and this also
saves time and money later when finishing the car. The other two
options ordered are the body fitment as I heard this can take an
immense amount of time and effort and also the body cutouts to
be done at the factory. I plan to get a transaxle from Fran at
Superlite cars as he knows what to get and said he could get a
good price. Fran will also be the one building the car. The kit
takes 4-5 months for them to make it.
