GTV-S2000 (warning not for the Alfa purist)

[Keven]

Mike,

Yes, I have an '05, I will get the thing running with the stock computer,
but if I want even more power, I will convert over to a Haltek. They
have computers that plug right into the S2000 wire harness

Thanks for the compliments. It's going slow, but I am trying to do a quality conversion.

look awsome. love the squareness of the tunnel... but it would look better if you made the interior a modern race themed car...

good work

[GoldCloverLeaf]

explain.....

[jazig.k]

ill find some pics... thatll be the best....

when you think about it the body wouldnt suit the idea totally, but the new, late modle engine could tie it all together
post pis soon

may i ask why u picked the s2000? Doesnt that motor have have a really high powerband that starts at like 6k rpm. Personally i think a ca18det or an sr20det swap would be absolutely badass. But then again im a nissan/datsun buff. Its a very common swap on the datsun 510 which (from pics) look to be about same size as the alfa gtv so i think it would fit without mods to firewall. Im not picking at ur project infact i think it will be sweet. I was just wondering why you picked that motor. Goodluck man and cant wait for more pics.

[jazig.k]

sizewise, the sr20 would fit almost all alfas...

i recon a sr and a 116gtv would go awsome together... but if i was game enough to go a s2000... i think itd be better...

just imagin seeing and hearing a 105 pulling 7krpm past ya on the hyw!

anyway, i couldnt find the mirage i was thinking of for the race themed int... its a light lilac with the custom circut board window tint if anyones seen it before.

I posted a pic of a 75 with a red top SR20DET awhile ago. The car was painted yellow.. located in NZ from memory. Myabe i posted that on GTV6.com... cant remember. Lets see pics of your 510 dime.

[TwoDoorDime]

sr20 can revv past 7k easily and the ca18det has been known to go as high as 10k on short burst without any damage. But prolly 8000-8500 is the safe limit. If i was gunna go through all that trouble then id try an rb series motor rb20det or rb25det (but they are prolly to long). If i didnt wanna cut firewall prolly go with ka24de-t ca18det or sr20det. But none the less that is going to be a very cool car.

I dont wanna be a thread jacker but here are a couple pics from when i bought it. Much diff now. Getting FULL resto. Down to bare metal.

[Keven]

Where are those thread marshals when you need them?

Why the S2000? Top reason is it generates the most HP/Liter
for a normally aspirated engine, along with high reliability, race
proven, etc etc. Also I get 6 gears to play with.
As far as the high reving, most Alfa's need to be reved way up
for the power as well, they just wont stay together at 9K
unless you build a race engine for a lot more that I paid for
my S2000 motor (I looked into this as well)

I also considered a twin spark, but the prices for the motors are
silly here in the states, and the availability of parts here in the
US is not good. I was quoted anywhere from $8-20K for a rebuilt
motor (no tranny, and not even new!!). I paid about $5K for a
2005 S2000 with wire harness, computer, header, tranny, front
suspension, & brakes. Just cant beat that price...

I do admit to ignorance of Nissan/Nismo products. I know the
Skyline is bad-***, but only in Japan, I also really like the Z
and the G35 coupe, but they are V6.

I love 510's, always wanted one of them when I was in college. I had
a buddy that put a 260Z motor and tranny into his 510, along with a
great suspension kit, it haulled ***!!

[TwoDoorDime]

yeah man the 510's do haul *** with anything but there stock motors. 96 h.p just doesnt quite cut it 36 years later. Im sure the f20? i think will be plenty of power for the little alfa. Cant wait to see more pics. Man i wish u lived in San Diego come over and do some of that metal cutting and weldin on my 510 get rid of some rust anyway good luck. Ok i got a quick question i JUST got into alfas like 2 days ago (saw a pic fell in love) dont even own one just on here to read bout them maybe a future project or something. This maybe a stupid question but like i said i dont no squat about these cars. Do the gtvs have IRS? i assume they do. sorry for the dumb question i just wanted to find out

The GTV has a solid rear axle. The suspension is called a DeDion design(ithink).
More knowlegable people can chime in, but it is essentially held by locating
arms with springs and shocks at each end, and flex is controlled via a trunion.
A lot of racers use a sliding block rear end. If you want to read more about
that, do a search in the suspension section of the BB.

BTW, you might want to look closer at my welds before you have me work on
your 510

Kev,Great project here...

One question ??
Does the Honda engine operate in the same direction a the old Alfa engine??

I ask as I dont know.I thought they were counter rotating engines...

Barry

[Keven]

Barry,

A lot of people have asked this, and has been covered in a previous
thread. The transverse mounted engines are counter rotating,
but the general consensus is that the S2000 is not, as it is mounted
in a linear fashoin, same as the Alfa.
