Jason (Kent) MK1 Cab 2 litre cross flow (45's)
« on: February 16, 2014, 05:16:20 pm »
Hi all,

Just wanted to share in amongst these great hi spec cars. There's great help and assistance from JMR for all level of projects, mine being far more humble. A 2L conversion of my std 1.8 GTI Cabrio.

My project is a 2L AGG block with an AKL cross flow head plus twin 45's

Jason has given up his time to help me as a relative novice and pointed me in the right direction. The AKL head is with engineers for work on the valves / seats, d sections removed from the piston crowns and I'll be doing some tiding of the ports, calculating the head cc, new tdc position and skimming the head / block. Jason tells me I can impress my friends with talk of 40 thou squish and 11:1 c.r  ;)

Target for engine 150bhp

- Engine block AGG (GOLF MK 3 GTI 2.0 8V 1995-1999, PASSAT 1995-1996, VENTO 1995-1997)
- AKL head (06B 103 373A) - Ported, cam'd by JMR
- Work on head, pistons, valves, skim per Jason's instructions
- New fast road cam from JMR
- Inlet manifold - JMR
- Twin Dellorto 45s
- Throttle linkage to suit the carbs and a fuel pressure regulator
- 4 1 exhaust manifold
- Replace fuel pump with a Facet or similar electric unit
- Remove the accumulator and all the old fuel lines, replace.
- Use the factory relay and wiring to power the facet
- Retain existing DX Dizzy and TCI module
- Use the original breather to a catcher?
- Loom, plug it in as it was before, and bin off all the left over plugs once you're done.
- Remove dash to bin out unused wiring and facilitate new wiring from the boot . .
- Relocate battery and washer to boot
- Remove servo and pedal linkage
- Fit HRCP brake bias box
- Dual reservoirs added
- Remove scuttle
- Re position radiator to allow airflow to carbs
- Top fill rad, bin out expansion tank and associated plumbing
- Inlet manifold - JMR the 16v on this site.
- Bin out the original oil cooler and plumbing and install Mocal take up with stat and oil rad
- JMR Mounts
- up rate anti role bars, brace top and bottom at front, top at rear
- Poly bushes and Gaz coilovers
- replace wishbones



AKL Head / gasket

No need to weld / re-shaping the oil drain / crankcase to head vent located in the front of the head (between cylinders 1 & 2), however use a hi spec metal gasket Victor Reinz part no 61 3180 00

However, in this particular set up the AKL head will require the front left and front right cylinder head bolt holes opened up to 12mm to allow the M11 head bolts to fit. This is because the AKL code 1.6 06X type engines utilise M10 head bolts, and these outer two cylinder head bolt holes are partially machined smaller so they are a close fit to the head bolt and thus align the head on the block. If you use a head from an AFT code 1.6 EA827 type engine then this modification would not be required as they utilise M11 head bolts as standard.

Thanks for the help and contributions of Jason, Dan, Chris for much of the above information and spending the time to mail, call and sharing their incredible knowledge of these cars and engines!!

Hi all,

 - Head with engineer, have my perspex and burette ready waiting for it's return hopefully early next week.

Old engine out, and gearbox off the old engine today, loads to do! But feels like progress!!

Hi,

Going to start to systematically bin some of the stuff in the engine bay, as the ignition is going to be simple with the carbs I'm guessing that all of this can go (apart from the coil and dizzy), would appreciate some assistance / guidance as I'm no sparky!

Ahh...looks like your on the later system being a late cabrio...you'll need an early GTi distributor and amp so the advance can be successfully swung in old school terms to suit the carbs better.

Carb jetting is easy once some carbs are found.

An upper strut brace helps but a lower one helps most.

Thanks, I've got a 2E dizzy, need the adaptor ring I believe. Sorry what do you mean by "amp"? Yep I've read it's the lower bracing that these need, will do the top as well to just to complete the job :-)

Hi Jason,

What t'other Jason is referring to is the ignition controller module or TCI as it's sometimes called, I have a few of these so let me know if you need one.

Cheers,

Tim

OK that's the small unit at the top of the picture (that connector 7 plugs into) but from a 2E yes?

If you have one please - the list is getting longer, cover plate, controller module  ;)

Tell you what, just get JM to stick you're new engine in mine, seems fair - sure you don't really need 197bhp!!!

What off!!!! lol

PS I'm going to check mine to make sure, the loom on mine only has the dizzy connector, not the other two as well so it may be the older version, I believe the older TCI is part number 071 906 233.

PPS Must stop looking at ETKA as bedtime reading . . .

Maybe I missed a detail, but if you're running carbs and no ECU, you need a dizzy with a built in advance curve, such as a DX one from a KJet car. A 2E dizzy has no advance curve.

I clearly need guidance on this. Firstly I'm a novice so all help welcome, my start point was the 2L conversion on the Club GTI site, the guidance there re the dizzy being the following however clearly this assumes injection / ecu etc. This from their 2L thread;

I used the AGG block where in the MK3, the ignition timing is controlled by the ECU based on 1 pulse per revolution from the dizzy. The MK2 is more traditional in that each of the 4 sparks comes from the dizzy. The early 2E block uses this method too. This means that if using the AGG block, you will need to get a dizzy from a 2E. I’m not sure about any other block but assume the 3A from the Audi would be similar to the 2E and be fine with its original dizzy.

So I have the original dizzy from my DX engine and one from a 2E which I've got from eBay. So my DX dizzy is the one to stick with then??

PS I move over here after being put in touch with Jason and him kindly spending some time talking over the phone and via text and realising that whilst the number of people on his forum may be lower the quality of information and wealth of knowledge is far greater as is again being demonstrated here!!!

We're humbled.... 8)...but yr right....lol

As mentioned above and what I was getting at earlier, you do indeed need a DX distributor & amplifier pack.

Yup -  what he said - DX Dizzy and amplifier, with an adapter ring and the drive gear from a 2.0, I think.

I would say I have a spare DX dizzy....but the spare one I head was shipped down to JM awhile ago, so it depends if he still has it or not??  :P

Tim,

Got almost all I need, my original DX dizzy etc, think I'll just need the adapter ring.

Plenty to do . . just off to Gosnays to pick up the head and piston crowns, got my perspex and burette so will be passing the cc number and piston TDC number to JM for calculations for the head / block skim  :)

Pass away !

Don't forget some light grease or vasaline to seal the perspex.

Update 1st March

Another good day, moving forward . . 

Head back from Gosnays, valve / valve seats done, piston crowns machined, wife was bemused as I headed to the garage with perspex, vaseline, a syringe and burette, it's all very technical I said, she called me something under her breath, I'll find out later  ;D

32.4cc combustion chamber
0.01" clearance at TDC
Piston crown 14.8cc
Metal gasket 0.08" (not compressed)

    

Then on to some engine bay clearing, there was me thinking the internal combustion engine was mechanical . . .  what could possible go wrong during the re build???!!!
