and still running cis! do tell!

[vwturbofox]

yes i will be running cise i will be using 3 cold start valves in the intake mainfold plus my meth injection i have my wideband installed and i will tune it as i go. sounds crazy but it will work

[vwturbofox]

I have bought by header flange and pipe to make a custom turbo header and then i start building

[fastrabbit]

i ordered two from them too... going to make my own top mount header.. i have the same power goals..

but mine is in a caddy

just bought a tig welder and started fabbin small parts

good luck

[vwturbofox]

yeah its a great price.

[vwturbofox]

so i have been thinking and well i wont be doing custom turbo header cause i got a sweet deal on spa mainfold for 90 with shipping brand new. bought an aem wideband and some control arm bushings also not doing gt3071r i chose dbb t3/t4 50 trim .63 ar just like my buddys srt4 that will be coming soon. i will be using cise on low boost 12psi if it doesnt work then i will go to aftermarket ecu then.

[vwturbofox]

manfold was cermaic coated. also lightweight intermediate pulley never did buy one when my intermediate shaft was lightened and balanced also got some wire sleeving that is heat resistant and have a throttle body spacer that will have my water/meth injector i dont like the location i have it now.i start tear down tomorrow pics

[snowfox]

Seriously.

The Fox CIS unit is generally known to only be able to deliver enough fuel for ~200-250, according to fairly reliable sources. I recall Jonathan managing to make a lot of power on CIS - but he used a CIS unit from an 8 cyl MBZ and ran 2 injectors per cylinder. (One in the head and one in each intake manifold runner, if memory serves...)

Not trying to shoot your goal down, just remembering some past builds. I'll still be watching this build regardless.

Good luck!

[vwturbofox]

well i will be running audi 5 cyl box 3 cold start valves and water/meth plus Porsche 930 Fuel Pump 400LPH, psi 140. those 8 cyl MBZ tend to run to rich cruising and makes big turbos evan lagger i like leaner fuel ratios befor boost hit it alows better spool. i will activate 2 injectors by hobb switch then two by a rpm window switch then i will just tune it and have fun easy as that.

[snowfox]

well i will be running audi 5 cyl box 3 cold start valves...

Got it. Missed that part somewhere along the line. Nice. Is it rising rate like the old Volve 240 turbo units?

[iluvfastcarz]

Fastest Fox in Washington haha. Keep up the good work!

[vwturbofox]

iluvfastcarz i have plans of beating your quartermile time
i bulding set of traction bars, limit straps and stiffer springs in the rear and sticky tires. i have another tranny that i will weld the diff and put in for the drags cause i cant find an lsd i dont think any one will ever have a sick fox like yours we just cant find trannys strong enough i loved you 20v fox i have seen your new build that is sick bro should do good in the quartermile

Less power will probably result in a better 1/4 mile than mine. I had to turn the boost controller down to the lowest setting (10 PSI) in order to get the fastest time. Welding the diff might help, although that method was already tried in my Fox with the 8VT setup and lasted for one trip around the block. Traction and transmissions that can handle that kind of abuse are our enemies for that kind of racing, I still wish you the best of luck and will be paying attention to this thread.

[VictorArrabal]

Good luck on your project, but here in Brazil we don't use this header in cars with more than 300hp...They don't have enough flow to deal with big turbos...giving lots of backpressure...

[Dave926]

In brazil you guys build 1000hp 16v's that split the blocks in half lol.

Gl with the build, I like homebuilt cis-e turbo systems they are so much simpler

cis-e turbo is faily easy. some pics of my intake mainold with cold start valves installed and lower intake for my cis-e box thats off a volvo and cut it installed 3 inch pipe instead of 2 1/2 doing lots of wiring right now

[Difus]

I think someday I will understad that injection...
And for what I see, the CIS is something like the brazilians 2E/3E carbs for that kind of setup. Maybe not the best choice, but works fine.

Edit.: 400 posts, after five years.

[vwturbofox]

all my parts are here turbo blanket,header wrap gaskets all the other goodies.turbo came today big boy 50 trim should be done this coming week then all test and tune time.also finished most wiring and put new timing belt and pulley.this fox is going to haul A**.

[vwturbofox]

did some fab work today thanks to my brother downpipe o2 sensor bungs wastergate dump and turbo installed exhaust wrap,turbo blanket and the starter blanket she looks nice in that tight space

[vwturbofox]

The beast is running and drives like a wild animal.currently running 15 psi 6 degrees timing and fuel is spot on took a few trys the air/fuel stays rich when rolling into boost around 11.5 then leans out to 12.2 a holds it till redline 6500.this turbo is crazy drives like normal then some lag then hang on to the wheel hits full boost around 4800 i think i have a boost leak no more wheel spin in second gear cause the boost comes on smooth then hits hard. jumping on the freeway is fun third gear wot then a second later your at 6500rpms thats with the psa tranny i lost my camera so i need to find it to take pics and then a video. who said this couldnt be done with cis-e + big turbo

[JGWarner]

Looks dangerous! Fantastic work.

[ziddey]

awesome. are you just using the msd coil or the whole ignition system? I suppose meth injection could probably take care of any preignition. You deleted / never had an AC compressor? I'd give a nut to be able to keep the compressor and the chassis intact.

awesome.

[Edcon91 II]

I am very jealous....

Just out of curiousity, how much $ do you have invested in the turbo build?

[vwturbofox]

jgwarner-dangerours thats half the story i did a shake down last night with my buddys sti that has bolt ons etc 18 psi and i was in second going on the freeway my brother told him to jump it so then i went he couldnt catch me then third gear came i left him like 10 car lengths easy this car is scary. Today weather is good so i might tune some more and turn it to 20psi and see what happens.

ziddey i am using msd wires and pertronix coil 0.6 ohms with iridium plugs gap at 0.25 yes the meth helps a lot and i run 92 octane with that as well.no my car didnt come with AC it would be super hard to run AC and turbo.

Edcon91 II i have invested in the whole car about $3,500 turbo setup around $2,000 and the car was free

[vwturbofox]

some pictures of the beast. later today a video




3 inch exhaust with new dynomax vt muffler

[ziddey]

checking for radar in the sky?

[vwturbofox]

checking for radar in the sky?

yes i am. no it still picks up all the radar in town and has saved my A** from tickets i am buying a new one soon that one is like 6 years old now time to upgrade the reason its like that i broke the crapy bracket it came with it.

[vwturbofox]

today i was pulling my spark plugs and checking them and number one cyl the plug pulled some threads out with it so what i am doing till i get a new head redone i put some high strength loctite on the threads and lucky i could torque it down to about 8 pounds simple fix sounds crazy but it work for now .Since a new head is in the making maybe bigger cam crazy p&p etc.on saturday i turned the boost to 20 psi and fixed boost leaks throttle body clamp was leaking now it spools little faster and second gear gets crazy tire spin and hop and 3 gear with all that 20 psi is just crazy but i turned it down to 15 psi cause that was enough for me.

[instg8r]

cant wait to hear and see this on a vid

[vwturbofox]

cant wait to hear and see this on a vid

hopefully the rain stops so i can do a full video and still need to fix my oil burning.

[Murder_MItt_Dubbs]

looks sick as hell dude, awesome job.

how involved was the fabrication for the front end you have?
i have an early westy core, grill, and fenders i was going to put on my rabbit but thought it would be badass to mod the fox with it.

looks like you kept the front stock, just made the grill fit and corrected the hood/fenders?

that what i did just made the grill fit welded up metal on the corner lights and welded up the head light buckets and called it a day its really easy to do.


UP dates on the beast.Start off nobody buy the new dynomax vt muffler what a pos the flap slams shut when i turn the car off. The idle sounds like a tractor with one of those rain caps you can hear it flapping around So i repeat dont buy one i am returning mine for a refund . the fox burns a little out the exhaust i think its the head cause it hasnt been rebuilt in a long time so now i have a new head going to port and really opening it up maybe bigger valves and a bigger cam should be fun. tranny is still holding the power down thats a plus 5th gear makes a little noise though

I have followed this for a while, always loved the recklessness of it Is this your daily as well?
