cheers only homemade stuff as i also did a 71 vw beetle and fitting a complete volvo 5clyinder turbo from a ex plode , friggin nuts runing 1.5bar /rwd drive ,,im aiming 4 500bhp 25psi,,ill tune it in stages thow ,

500bhp .  That would be insane.

 well i defo know the engine and gearbox are capable , thats the good thing about stock vw engines ,, lower the compresion and make them fly

 was looking under the bonett this after and thought i dont like these old plastic things ,, so thought chuff it ill make one lol

quick cut and weld and added a few pipes and a cap


then thought might as well add the washers on a sepete part so they will be hot water on the go


just have to make a quick bracket and another to top the washer bottle up /pipes poped on job done

 not mutch just finished the header off ,and added a bit of vw washer cap ,,as im bisy with other stuff

also fitted all the water system pipeing but i carnt seem to find were the bottom heater matrix hose should be coupled to anyone know on mk4 24v engine?as ive not spare pipes so assumeing one may need a t piece fitting :banghead:

should be a METAL pipe that runs around the back of the engine on top of the exhaust manifold and it couplet up to that iirc

Andy

 ive lost me , so the bottom heatermatrix hose , comes out and runs along the top of the exhust manifold and then contects to were/,,as i carnt see a spare pipe to couple it too

 had a water piping problem ,, now sorted thanks to ekta

 not mutch to add been bisy , but made a quick turbo sheild

 not bad the turbo jacket should help spool it, and reduce lag

 reallyi thought it just helps heat problems not bad for a 5.00 lol

How is a jacket around the turbo going to help it spool?

Keeps the air cooler and more dense before charging

it also prevents heat soak from the hot side

 first ive heard of this tbh? as u think disbusting heat would be the best idea , i only made it to try stop a bit of turbo heat  burning my bonett lol

 Powernut after reading & looking at pictures in this thread.  

I lost for words

10/10 for your work mate & best of luck in your project 

cheers all fun i reckon ,,, 

few bits of piping /one way valve for auxity pump


then i had a trail rev for 10 mins and it over heated reason was the single fan carnt cope , so added 2 bugger and all is well

caddys coming together at last

the other main advantage is it keeps under bonnet temps down as the jacket stops the heat being transferd around the engine bay and more imporantly into the intake causing heat soak, as you only want cold/dense air as dent reform also stated

 god im fed up , this ecu has started playing up yet again , as im runing low inpendance injectors ,the ms unit has a built in curcit to make them run , as im sure its gone faulty due to major over fuel and dosent matter what i try to do ,its missing and smokeing like a deisal , so i may have to bypass this and run high inpendance ,,

then while tuning the spark and fuel maps , the engine started smoking badly , i thought the worst .but found the problem which was the turbo oil feed hole was too big (8mm ) which was bypassing the turbo seals so added this one

and also fitted a 90 elbow too , so thats sorted that problem out , no smoke , lol

then got the laptop back on the go to find , my air tempture not working so went hunting at the local scrap to find one , made a new therd and fitted and works a dam treat too ,,

(all these little things do help trust , just awaiting now to try a new ms part , if i get no luck il thow some high inpedance inejctors in , fingers crossed one or the other sorts the problem ,,

Your knowledge is awesome.  Very few people would know what to do with wiring a ECU.

You are a legend mate..great work.

 cheers guys its not hard to wire them up its when the internal settings that are the head ace , lol easpecaily when u just entre a redom number and a blows a aprt of the ecu lol , all fun i guess , ive managed to get it runing and reving again , beteer then eariler but the mpgs or thew the roof 1 gallon per 10mins at 2000rpm lmao

Forget miles to the gallon....minutes to the gallon all the way!!!!

 lmao i think i may need a 45 galon drum in the rear to get from A to B lmfao

im sure its the low indepance inejctor cuircit which has gone down , so ill adapt somehigh inpence injectors instead see what happernds ,,

Said this before but real Jedi skills on show here!

Always good to read the updates and see your making progress.

 nice one pal ,,

little update , yes dam temp gauge working

then bit of a problem with getting a vr6 mk3 rev counter working , but with a bit of tickering with resistors it works a treat lol


 and unsure why but when igition turned off needs stop as there are , then when igition is switched back on , everything re sets and works fine,

are you sorting the ecu off the top of your head or are you wiring it using information sourced from the net?

just wondering as thats mental if your just figuiring it out as you go along?

 quick start up video on 5 pots , lol plug down

Mate that is awesome!
Loved reading through this thread looking forward to the rest!

Sounds awesome?

Swap for my 1.4? lol

 cheers guys its sorting the fuel gauge whats the problem unsure how its wired to work dam thing

 cheers guys its sorting the fuel gauge whats the problem unsure how its wired to work dam thing

I have just finished fixing the fuel gauge on my T4....   Not quite like what your doing but it seemed that the sender unit had a rheostat for the float unit that varied between 2 values which wasnt for example 0-100 ohms it was something like 146-295 ohms between empty and full, Try it out with different resistors!! - hope this helps

Looking awesome still!

Mark

 cheers mark ive tryed 2 varible resistors and a few asorted resistors but dosent make the dam gauge move

might be outdated for your cluster but try this

 tiny update ,, managed to get the dam feul gauge working too lol
(saves buying extra gauges and re wireing)

 quick spare 10mins this after so thought chuff buying a 13.00 plastic gauge holder ill make one which will fit better too ,

quick grind up bobed gauges in job done , just awaiting the oil gauge to arrive

i reckon 30psi with be plenty full lol
