I am going a different route with a new Pinto I picked up yesterday.
Instead of a blow thru turbo setup I currently am running I have been
hanging out with the air cooled VW guys and am going to try a draw thru setup.
Sort of like Buddys Turbo Pinto but a 2.3 based deal instead of a 2.0.
A friend is making 512 hp out of a 2280 with a draw thru so we are going to give it a shot.

The car was a 2.8/auto/8in car and will eventually be a 2.3/C4 brake/8.8 car.
It will be a 85/15 strip/street deal and will post pics later.

Just glad to be here.

Hi Chris, glad to see you here. Not a lot of true hot rodding going on, but a fairly informative site. I like the draw thru idea with the 2.3. It makes for a lot less headaches. Got tired of all the BS on TF, so I don't post there anymore. Pretty much just lurk on this site, turbopinto.com and TF. Good luck with the project.

Curtis,I too have grown tired of the crap on
TF and only lurk there.
Maybe we can pick up the hot rodding side
of the Pinto here.
I am on turbopinto also as well as the YB and
turboforums.
I have already had people say the draw thru deal wont work
but after talking with the VW guys I am going to give it a go.
Going to start with a stock location deal and maybe try a front
mount(have a scavenge pump already)but that will mount the carb
between the radiator and valve cover.
We will see.

draw through works fine, it does make adding a aftercooler interesting, although with all the meth injection stuff out there now, you can get by without it...

I have done both the draw through and blow through setups on both a 2.0 and 2.3 ( 2.5) motors. In my opinion, the blow through works better ( on a pinto) for a few reasons. First reason is, on a pinto ( other than using a intake manifold like on the 79 turbo capri/mustang ) the carb will be sitting low ( that is lower than the intake manifold). This may cause a puddling condition in various areas. Also, as mentioned above you cant use an innercooler with a draw through ( because of the puddling condition and the fact that the gas would condense on the innercooler and fill it up). The VWs all have the carb at the highest point and everything goes down hill, which makes it work real well. However, a " real good " thing about a draw through is that your can use a Vacuum secondary carb which is ( in my opinion ) the best way to tune the secondary side. On the blow through you have to use a mechanical secondary, ( which in my opinion is a royal pain to tune). The issue here is when the secondary side opens up its about the same time boost comes up and with out the tuning ( al la vacuum ) you cant get the fuel to dial in at the correct time i.e. early or later than the secondary throttle blades open. On my 2.0 I am using a holley 650 double pumper and just installed a restrictor plate ( for the secondary side) because when all 4 throttle blades are wide open I get a condition when too much air is being forced into the combustion chamber and my motor just cant handle all that volume. Gas however is what I need ( and lots of it) So, I need about a 500 cfm double pumper ( btw, a 4 barrel carb and a 2 barrel carb is measured differently so a 500 cfm 2 barrel would not be the same as a 500 4 barrel ) but i digress. I would toss my current carb if I could find a vaccum 4 barrel that would work in a blow through deal ( and not spend thousands). So, anyway I hope you get the right combo working and please show us pictures. Let me know if I can be any help.

Glad you guys are here.Look forward to any and all info you are willing to share on turbos.Picture s are always a plus too.

Hey turbopinto72.. .there is a company called Pro Systems Racing. Don't know if you have heard of them or not but they build carbs...and damn nice ones. I had one built for my 347 and it was spot on. They take all the info and build a carb to match what you have. My carb was about $700 and was a 4150 dbl pumper 730cfm. They could build a carb for what you have that will do the trick. http://www.prosystemsracing.com/index1.html

I have a CSU bt 750 onmy 306 Turbo Zephyr.
C&S aerosol carbs work well also for a bt setup.

Racer, if it works......... .... I would by a set up from you to run on my 72.

fast64ranchero · « **Reply #12 on:** January 25, 2012, 12:47:23 PM »

Turbopinto72, Have you tried increasing the Power valve ciruit in your current 650 BP? I ended up drilling the Power Valve circuit to 92 thousands if I remember right to get the secondary side to feed correctly, worked great, and i could still run a normal size secondary main jets.

I have yet to find a cure for the transition from vacuum to boost with a blow through set up, I just couldn't get rid of the huge rich spike durring transition. i think i might still hold the record for a Ford inline 250 six (modified Ford iron head) @ 497 whp and 501 Ft lbs

Picked up a decent 3310-2(780 cfm) Holley for
100.00,a Holley black pump,regulator and a
MagnaFuel regulator for 125.00.The Magnafuel is
boost referenced for 1 to 1 if I want to go blowthru.
It was a deal so I got it at the same time.
The carb mount is coming from the VW community
and I will post pics soon.
Got the Esslinger intake from a member here and will make
an adapter to go from the 2 bblFord/Holley pattern to a 2.5
tube for the turbo outlet to connect to.
For the turbo mount I am thinking of using the Stinger center mount with a T3 to T4 adapter
which will mount the turbo up about 2.5 inches higher than normal.Its a Precision 64mm
turbo with a 2.5 outlet that will mate to a 2.5 tube over the v/c to the sheet metal intake adapter.

Very interesting build. I`m still on the fence about taking this totally complete `78 and cutting it up to back half and put my 572 in. I would love to see your progress on this turbo setup. I also would like to see where you end up with carb choice. Looking at the only mount option, puddling is going to be the biggest concern. I know no one really likes them but a "quadra bog" carb would be a great choice for atomization imo. On the skinny, what can these stock motors take as far as boost and power? And I meen stock, maybe a cam change.
Sorry for the hi-jack. Un-intended, just waying options and satisfying curiosity.

racer99 · « **Reply #15 on:** March 03, 2012, 11:50:37 AM »

No problem.A guy in Fla has gone 32-36 lbs on a stock
2.3T and been 11.30s I believe.
Stock as far as head,crank,rods,pistons.
And I believe he said it had a factory E6 exhaust
manifold.I am sure the headgasket and probably some other
stuff had been done to it.
A good tune and C16 or other race gas would be essential
to it staying together.

I have a 780 vacuum secondary Holley and I am sure there will
be some issues to work out as far as the fuel goes but we will
see what happens.Waitin g on the crab to turbo adapter and getting the
sheetmetal adapter for the intake .

johnbigman2011 · « **Reply #16 on:** March 03, 2012, 07:16:20 PM »

Racer, how much Hp are you looking to make???

racer99 · « **Reply #17 on:** March 03, 2012, 10:08:41 PM »

275-325 to start.
Got a 75 shot to get it
up on the convertor.
Meth inj over 15 lbs.

thecustommuffler · « **Reply #18 on:** March 04, 2012, 09:39:11 AM »

32-36 lbs? Damn! That should net on a stock motor somewhere (I`m guessing) around 340 hp. With the original 13`s, that would be a tire frier. The only thing that scares me on a build like that would be remembering the laughable SVO. Now granted, turbo technology has come along way since but popping the hood of a SVO `stang and the sound it made wasn`t Americana. But it sure would be alot less work over the big block and back half. If this car wasn`t so "there", I wouldn`t think twice about the saw-z-all.

Got all the interior out and the floorboards are almost perfect.
Seriously thinking of going ahead and putting at least an 8 point
In it now as opposed to later.Pulling the dash out and stripping all
Of the stuff behind it is next.

Thats awsome, i like where this is going, please tell me this is your idea of a daily driver, then i wont feel alone

Not a daily as such but a weekend cruiser and car show night toy.

Pro Systems Racing is the Ticket...they are located here in Muskegon MI. and FL . I have worked with and know the support man there Brad Hosmer. He worked at our Ford Dealership here in Muskegon for years as a Tech. Yes they will build to spec's of your build up- thay are turn key, but$$ . They do Big name Drag Racing and Track. ....

racer99 · « **Reply #23 on:** April 26, 2012, 03:20:38 PM »

Moving this over from the 80 Hatch to the 79 wagon.
Might keep the 5 speed as the wagon is a manual.
The 8.8 is almost ready to go under the wagon and
I will put the 10 holes on it this weekend.

RSM · « **Reply #24 on:** April 26, 2012, 07:03:26 PM »

Pro Systems Racing are some stand up guys....hands down. They built a carb for a 347 I had in a Mustang. The carb and a ton of other stuff was stolen just 4 days after putting the carb on. I called Patrick and told him to be on the lookout. 9 months later I get a call that someone in Georgia had called about it. He gave me the guys number and it wound up that he bought it on Ebay from a guy in Phoenix. It was nice to get it back!! As for the carb, they built it with specs I gave them on the engine and it was dead on perfect...firs t time!!

racer99 · « **Reply #25 on:** May 03, 2012, 12:18:56 PM »

Welds 15x3.5 on the front,10 holes with 295/50/15s on the rear.

Still waiting on the turbo/carb adapter and
the intake/turbo adapter.

Found the wagon on CL for 500.00.

No rust,needs slight bodywork nothing major.

2.3/manual/no ps,no ac,no pb,no roof rack,just
basic transportation .Runs like a 3 legged dog on crack,
that might be because of the 47 vacuum leaks it has.

Will post pics later.

johnbigman2011 · « **Reply #26 on:** May 03, 2012, 05:33:53 PM »

Well that's cheap enough.. I'm looking for another one ( car ) here shortly after I get the yeller feller going. Hate to see a good 2.3 sitting and wasting away. If you have I a successful build I'm interested in fallowing yours for ideas. Always wanted a turbo.
