    After a few weeks of hard work the car started taking shape fairly quickly, obviously I still had work to go to and some lessons at college to attend so I wasn't on it 24/7 but progress was fast :) it

    So once the engine was out and the car was stripped it was time to get a doner car, I wasn't keen on doing all this work to end up with the same gutless 60HP 1.4 8v so a more powerfull engine was a mu

Loving this thread.. was only talking about the idea of doing this to mine the other day!! Would be great to see how it is done and what issues you had with fitment etc.

Owe a massive apology to everyone for the no posts over the last few months but the thread ran out of space for pictures and I got distracted from sorting it out now but I've created a photo bucket account so I can link photos into the thread and hopefully you get them! Anyways I believe I was at the stage of showing you the doner car I would use for the build... I picked up this mk4 GTI with a AGU lump for £650, hopefully make some of that back in spares :) I didn't mess around getting the engine an everything out as I was eager to test it in the polo bay :)

Cheers man imma try keep the posts up now :) Iv'e done a bit of research on this conversion but everyone does it differently and there's only a handful of usefull threads out there but hopefully mine becomes one of them :tongue: now that i had the 1.8T out and the polo stripped i couldn't wait to see how it sit in the bay... the thing really looked massive and doesn't allow much tolerance for space in any direction, so as the first task was to mount the engine i thought id better get the grinder out and start trimming so that i can get the engine to sit nicely in the bay in order to fabricate proper mounts! obviously all cut outs will later be reinforced and strengthened 11015211_859312510802308_192468929316082 17649_859312527468973_124082058713638993 11022413_859312567468969_853247286480566 11377177_859324490801110_323791203015246 11109688_859324510801108_524095216698095 11165333_859324527467773_232815827864397 11147011_859312687468957_312704202500540 11062146_859312724135620_611496428926462 11391374_859312624135630_589600054003363 11391607_859312644135628_289397585566897 11053227_859312744135618_442384841435079 10425361_859312757468950_549029322401282 11026083_859312790802280_507804290466899

Now that id removed a fair bit of metal i retested the engine to see how it sat and the good news was it fitted quite nicely... so now it was time to start on fabricating some mounts, i decided to use the mk4 golf mounting point, so that was cut out and so was the polo's original engine mount point so the mk4 mount could be welded in, there was no going back after this! 11390139_859313010802258_879883560353322 11143312_859312864135606_475973459397848 11267060_859312887468937_120075601271874 10456824_859312814135611_785574808444540 11390010_859435397456686_729997724909455 11330028_859435417456684_644047504200941 11231087_859435440790015_350994198826458 11109431_859435460790013_548434028255642

Good thread which will hopefully make me a bit more confident on my 1.8T swap on my GTI :) I heard that 9N3 GTI engine mounts are a straight fit and bolt on to the mk4 1.8T motor. Doing the actual swap shouldn't be too bad but converting the loom will be the scary bit (for me anyway). I will follow this :)

  • Author

Iv'e heard that too but i don't think they are, you could maybe try modify a 9n mount to fit the 6n2 but nothings a straight swap on this which is what makes it a challenge

Little update, whilst the engine was all out i took the gearbox home to paint it a smart satin black, changed the timing belt and got some parts for the build :) went for a full ko4 setup, forge FMIC, BAM inlet, Forge charge pipe, VR6 Radiator , even won a forge TIP on ebay 11377359_859312920802267_921191518987328 11391350_859312944135598_944688401636918 10653770_859312964135596_293249337440940 11223605_859312984135594_689624022300857 11393202_859313167468909_610174811000648 11252394_859313254135567_703659463184213 1607132_859324387467787_6274238837356978

Right back to the mounts! so i decided to start with the engine mount first i would only tack weld this in before making a gearbox and dogbone mount so that i can make adjustments should the engine sit to high, to low, to far forward, to far back, to tilted or completely pissed... :| yeah it was allot to align properly... anyway first i made 2 plates that the mk4 engine mount could sit on, i would tack them in place, then tack the mk4 golf mount piece on the plates, then bolt the mk4 golf engine mount to the engine and mount and see how it all sat before making a gearbox mount :smile:11377329_859313047468921_418383067875797 19404_859313084135584_801633045033971619 11108852_859313107468915_593896548555818 11236553_859313124135580_872293637842387 1619403_859313144135578_2292586154859945

To make the gearbox mount i cut the cylinder shape mount off the original polo gearbox mount and welded that to a piece of angle iron which i bolted to the 1.8t gearbox so that the passenger side of the engine bay didn't need any modification atoll and i could use the original polo mount point, the reason i done it this simpler way is because i have future plans of fitting a 6 speed gearbox which will require a new gearbox mount to be fabricated anyway... after both engine an gearbox mounts were tacked in i did some serious staring and measuring to make sure everything was bang on straight! i was happy with my plates so they were fully welded in and i made 4 more plates/walls for them so they became little box type platforms, i also found the mk4 engine mount had to sit quite far to the right of the bar and it over hung the chassis rail so a small platform was made for it to be welded onto... (pictures speak a thousand words) i also put some filler on the bay basically making a start to some minor smoothing :paranoid:11390071_859313274135565_689041926385694 20426_859323897467836_333162799758457744 11390017_859323934134499_664629932514387 11391324_859435904123302_318631211654528 10537440_860507347349491_593391751392856 11351252_860507427349483_154612957559567 11222124_859435937456632_854111030339176 11351220_860507470682812_214121192585661 11119147_860507494016143_425839825343039 11350574_860507527349473_682660117371212 11201118_860507514016141_865514337737062

Excellent thread this. Proper cool. :-)

What kind of power you expecting out of this with the k04 setup?

Nice work! I'd have the front number plate in the centre, but each to their own! That'll be one quick car!

WOW!! what a thread!! absolutely great work mate!!

  • 2 weeks later...

Very impressive work bud. To do all that work at your age is a great accomplishment. I'm planing on a conversion from my 6n2 1.4tdi to a mk 4 golf 130 or 150 tdi engine. Waiting to see how the mounting is going to be done. Though I'm handy with the welder lol. Did you have any trouble with the drive shafts?

  • Author

cheers guys I'm hoping about 280HP summin like that then i can get a ko4 hybrid in the future when this turbo goes, and yeah only reason for putting the plate there was that someone hit my front bumper and made a nasty filler crack appear so that was just to cover it up

Now that i had a engine and a gearbox mount tacked in it was time to tackle the dogbone mount! i could have modified the polo mount but theres no upgraded polybushes for that mount so i decided to use the mk4 golf 1.8T dog bone, for this i cut out the polo mount and then cut the section of the mk4 golf subframe that the dog bone bolts onto, i then trimmed this down and welded it to the bottom of the polo subframe... 11391339_859323957467830_745663305718590 11391379_859324124134480_298174800112915 10502456_859324054134487_295843814502079 11011011_859324084134484_591101019325164 1554631_859324100801149_6341045474599201 11295632_859324140801145_378073382385944 11391786_859324167467809_657275432297589 11392809_859324230801136_637040367652536

after the section of the mk4 subframe had been welded to the polo subframe i made some walls around it to create a box section for strength, unfortunately my lower OMP strut brace got right in the way of the dogbone so instead of removing it i mounted the dog bone much further back so that it didn't hit the brace, however this meant that the rear wall of the box section was too close to the ARB... so to miss the ARB and allow some tolerance for when it twists during high speed cornering i had to make a slight bend in the wall so that the ARB was not effected, below are some pictures of the wall being mocked up with cardboard, you can see from the pictures the small tolerances of space there were and the bend that had to be made for the ARB. (pictures also show the reinforcement bar i welded to the 2nd bracket that comes with the dogbone mounts which i then painted red), the second problem i had with the box section is it didn't allow enough room for a 3" exhaust to go through so the grinder came out again to cut out an arch to make room for the exhaust, i then made an arch shape wall to weld in aswell, this completed the box sectone fabrication for the dog bone mount! 11393047_859324194134473_246970305312034 11351336_859324210801138_823349109313310 11207366_859324260801133_664541604664741 11074172_859324277467798_549849232304344 11050691_859324304134462_230003726000127 11013402_859324337467792_322420772441938 11377307_859324354134457_869097173337760 11377377_859324370801122_855479270103463 999629_867130980020461_64832642220308603 10676303_867131003353792_415411244248976 11390303_859435767456649_389494861100369 11904733_909008802499345_349831331002749 12002810_909008829166009_532585058674895 11059357_909008855832673_361304111082829 12009572_909008892499336_673644358418493 12003379_909008919166000_219141810930869 12004684_909008962499329_564474026005428 12004908_909008992499326_615337909177164

Now that ths dog bone and gearbox mounts were fully welded up it was time to weld up the engine mount so that all mounts were 100% it was good to see the weld penetrating through the engine bay into the inner arch in the 2nd picture, this showed that the mount was solidly welded to the side of the bay! I also got a VR6 sachs clutch and G60 flywheel for the gearbox this would be able to cope with about 300 BHP 11229401_860507734016119_431247150259638 11329803_860507700682789_851946222836709 11351424_860507924016100_744021743660696 11403398_867130356687190_253684327829479 10425167_860507977349428_274140515191022 11377374_860507954016097_450315441287183

How much did your insurance rocket with the 1.6 lump conversion?

cheers mate, the 1.6 was never registered simply because i couldn't... no one would even insure me on it so it was impossible, however now I'm older the 1.8t will be able to be registered and insured properly lol

So now that all the mounts were done and welded up 100% it was time to reinforce and weld up all the cut outs that were made... I first made some plates to weld in either side of the subframe to give it extra strength, I then also grinded back and seam welded the turrets that the subframe bolt onto as these are only spot welded from factory, an finally for the cut out in the subframe which was made for diff clearance i cut and solidly welded in 3 steel rebar's then made 3 plates to close up and finish off that cut out... 11390074_859435490790010_555534722194302 11219030_860507680682791_147417685059389 11258172_860507657349460_184660698108592 10355766_859435784123314_443473942333911 16707_859435817456644_730893568285154429 11143407_859435804123312_463426808145216 11143407_859435804123312_463426808145216 11390306_859435734123319_355728928089659 11390169_859435870789972_427064494942647 17185_860507574016135_404550274029855385 11401067_867129896687236_566906153341260 11254390_867130223353870_842954330395062 11535711_867130316687194_438893988343049 11377219_867130556687170_429331828856637

After that the chassis notch made for the gearbox clearance was welded up buy re-welding the inner wheel arch wall in, making an arch to fill the gap in the chissis leg and some more rebaring... all the welds were then seam sealed and ready for paint! 11390125_860507557349470_290713761482324 11377073_860507624016130_670411437339779 11391785_860507640682795_428232570768845 10985465_860507717349454_175796743171359 11351171_860507757349450_713140188860649 10557365_867129566687269_549167858282284 11401445_867129603353932_444792736428709 11232937_867129646687261_413284168774434 11406988_867129676687258_562340224766002 10509753_867129716687254_172191900894039 11393016_867130523353840_582032830293872
