I'm back!! Several months ago i ended a thread due to repeated delays and total frustration. I ended up dumping the original parts and crew, regrouped, and am now back with a vengence:cool: :D

Since then i've assembled a team just as dedicated as i am to bring my spider to fruition. Not only that, but everything has gone up several notches. The beast that will be powering my spider now will be one very, very nasty..

164 based
3.7 Litre
24 Valve
V6 Monster


Here are some highlights:

Brand-new, long-stroke, 3.2 litre 156/147 GTA crank and bearings
6 indivdual throttle boddies
GoTech PRO fully-programmable, stand-alone engine management system
Ross Racing aluminium-alloy pistons...ect

That power plant will result in just over 300 HP at the wheels!!:eek: :eek:

No bulges, extra vents or flares!! Nothing to give away all that power. Mated to that beast will be the 5 speed, 105 tranny - laced up with all new internals including close ratio and lightened gears (shafts, syncros..everything new) Then finishing off with the taller rear end of the automatic spider.

All the torque is going to be incredible and avalible down low in the rev range. Therefore, major body supports will be in place to keep it straight.

Thanks to "junglejustice" aka John at Glenwood Motors out of South Africa. The time you spent on the phone with me going over all my options, quick email replys and outstanding development of my engine was second to none. Respect bro:rolleyes:

This bad boy is slated to be completed for spring 07. There will be more mods to come and I'll be updating this thread as more work develops for all interested.

Regards,

streetfame

My money is on Spring 08!!!!!!!!!
All the best ....V6GTJ.........
V6GTJ,

I hear the joke brah! But i've been through so much crap over the last little while that nothing is going to stand in my way of getting this spider done for spring 2007. My team now is unstoppable:

John and Dawie at Glenwood Motors (over 30 years building/designing performance alfa race engines)

Joseph at Hamiltion Auto (who has successfully installed a twin turbo 3.0 V6 in a S3 - 2 years ago and not a glitch since)

and

Frank at Center Hill Paint and Body in Toronto (over 35 years of splashing n' moulding alfa's)

Trust me...It's on!!! Bleedat!:D :eek: :D

Thanks for the encouragement. All the best to you as well!!

Regards,

streetfame

87 Sprint,

Thanks for the encouragement as well. Good luck to you as well on your project!
I'll post what I can as more work continues. Until then, here are some more pics to drool over just as I did.:eek: Just check out the steel ring fire-seal setup that Dawie pioneered many moons ago:eek:Whoa:eek:

Count me in - I've always wondered what the esteemed Mr. van Rensburg and his band of elves could bring to life given a full head of steam - now we shall see!

Still - shoulda gone w/ megasquirt. It is the paradigm of the future.

Oh well, Go-tech will work, I guess.

And that engine is SICK :eek: :p :D

How does the fire-seal work?

Randy! I still owe you a phone call - me thinks...? No? When are you coming up, or is that off now...?

Any way, learned a great myself the last few years.... It is all about processing speed! Drove 3 cars on this trip with the new 44mhz processor GoTech Pro-X box - WOW! What a difference....

It is all about processing speed - how fast can that little man inside of the ECU yell-out throttle position orders from the TPS AND, as the accelerator is depressed even more progressively, how fast can that same worker repeat updates!? Then, how fast can the other little guys passing out fuel and spark respond and as the demand from said first little guy increases progressively, how fast can they react - are they only just now passing out orders/fuel/spark in response to old requests or are they keeping up with what's happening all around them....?

Multiply those orders coming in from the Lambda, water temp, air temp, boost, rpm, load, vacuum etc and by the way - will the MS do this every .5 rpm...?

That is where the smoothness comes in. Our GTA runs as if it is the stock electronics are in there! Smooth, without a glitch and the throttle response is unbelievable... It MAKES power! Period.

Many of the other systems out there still run 4mhz, 8mhz and 16mhz processors.... What does the MS run?

MS models until recently DO NOT handle spark - only fuel - you have to run a separate ignition module - one can only attempt to compare that with a fully integrated programmable fuel AND spark stand-alone system. The differences show up in the drive...

Ohhhhh YES!!

I'm subscribed to this thread now. Cant wait for the next post.
Thanks Simon! Doin' my best for the beast! Feels real good to breathe again on a new thread. Welcome to my spider's "darkside":D That previous engine just didn't have the pimp factor these Glenwood ones do...

Holla,

Randy,

Don't want to turn this thread into another mega squirt vs the world thread so i'll let John handel that one;)

Once explained to me...Go-Tech felt like the better one for THIS engine...

Word on the street in South Africa is that Dawie has an entire colony of midget elves about 6 inches tall busily working away on a few monsters at any given time:p ....John is just one of the taller ones...:D

Holla,

I just want to hear the sound of the trumpets. :p

Plus see you shame a Lambo or two...

Watching with much intrest. Keep the detailed pics coming!!
Keep those eyes peeled...I've got a few surprizes. So as i've said in the 3.0L into my 91 spider thread...

"...i think that this would be a more interesting thread, if i showed what was being done, rather than just talk about it..."

I don't want anyone on here thinking i'm just yappin' about a to-do wish list. What i mention, I either have presently or is presently being worked on.

Hey Johnny,

You gotta post up here that shot with those pimpin' yellow shoes. Here, i've got a pair i've only worn 5 times in three years cause they're so fly!! Won't even think of driving with them. Those pedels would mash up the white top "quick-fast":eek: So, quit readin' this and post that pic:D

To all the present subscribers to this thread...my bad for postin' the shoes. But when Johnny posts "that pic".....:D....you'll see what i mean...:D

Holla,

streetfame

Nice, but this engine is supposed to go into your 91 spider? A 12 valve BARELY fits in the engine bay how is a 24 valve going to fit? How are you going to mate the 105 tranny to the v6 engine? I know hans in atlanta and Nick in California who are master mechanics and they don't recommend using 105 trannys (to weak). They either use a maserati biturbo trans or a trans from a alfa six.

awesome, but only 300 HP? Here in Holland is a guy who really had 452 Horses (crank) on the water dyno with his 3.5 24V...
seeining as how advanced your engine will be, will it be (I know..) 'only'be 300 HP?
3.5L 24V V6 w/425 HP at the crank. non-aspirated?....Not a chance. Sorry bro. You have been mis-informed.

Azzurri,

All it takes is a properly designed plate adapter/spacer 3/4 around the 105 bell housing just as V6GTJ has shown. Mine is similar to V6GTJ's, except mine is home to the starter as well. As far as the 24 valver fitting in the engine bay? Not a problem;) The tranny? You'd be surprized how robust these trannys are - even in the stock form. But just for added security i've had the entire internals replaced with new components (shafts, syncros, sleves, ect..). As well, all tranny's gears are now forged "close-ratio" gears which have been lightened and hard shot peened for even extra strength. No problems here as well. I've spoken with Nick awhile ago. He said that as long as the tranny is in very good shape - stock even...all would be fine. Dawie has also agreed...

Hey man! Weren't you supposed to stuff sumthin' nasty under your hood?? What's the hold up??:confused: :D

i didn't know about the adapter plate. When i asked the same question a while ago i got a diff answer. Good luck with your project and be sure to post lots of pics.
I had a project of my own but time and $$ got me sidetracked, now i'm working on a diff project and i'm trying to get 150hp out of my fiat 500.:D

Are you gonna use megasquirt?

Truth of the matter is that the 24 valve heads are more compact - see the threads under Milano/75 - Fit with ABS...!

Also, the 24 valve sits lower in the engine bay than a 12 valve...

As for 450 plus crank horses out of a 3.5 Alfa V6 - maybe on a twin turbo- next you will be telling me that it is a 12 valve too...!? Never on an NA Alfa block. I will personally be doing some candle-licking (and I hate doing that...), on the day that you see 450 plus naturally aspirated at the crank from one of these motors in 3.5 trim no less!!! Nope - not a chance - at least not for two days in a row - the block pulls and the bearings go as soon as the block cools and stress-releases.

TT - yes - 600-700 hp at the crank currently running in SA cars - see this month's Auto Italia Magazine - our friend Stewart Kidgel's TT 3.45 in the Ultima running just 1 Bar....

Nah - I have been personally involved in 15-plus builds with Dawie now over 2 and a half years (arguably a man who knows where the power is on one of these things) and 300 to 330 for the street at the crank is as good as it gets, 350 to 375 for the track and 400-425 in full-race trim. We saw 301 AT THE WHEELS on Jes' 3.7 and my new motor should throw about 340-350 at the wheels here at sea-level.
