87 gtx scirocco tt288 cam with Kjet?

[jasonO]

After looking at various opinions on cams running with kjets i have decided to roll the dice and put a tt288 cam on my rocco.
I would not have had the kahunas to risk it but the tt288 cam and HD springs and head did not cost my pocket i had a set of nice wheels that look the part on mr golf loons rocco and the engine parts were for his now departed apprentice.So it was meant to be

Another positive is i can get the plenty of time to head ported and polised properly and get any parts i need as i go without rushing as my car still has its head on.Im uncertain of whether or not i am going to touch the bottom end at this stage unless i need to.I already have larger throttle body and lovely euro exhaust downpipe.I know they sometimes have problems with airflap but ill cross that bridge when i get there cause sometimes they dont.

I welcome any opinions here on anything i may need to do that i am not aware of my kjet is one of the lucky ones and runs perfect its only done 52k miles in a clean engine bay.

I am interested in all your opinions some experienced ones really appreciated any clowns that feel the need to post opinions when they have no idea post too i enjoy reading those you know who you are if your thinking of telling me to get it chipped first.

oneofthegreats golworx twinengtwinturbs please post i know you guys have done similar setups.

The opinions vary hugely so far and the final odds i rate at 50/50 so i dont want to put too much money on this horse unless i need to.

With a vernier pulley and reasonable attention paid to setting up, the 288 will run fine and idle pretty well. I had a 282 TSR 103 cam in my MK1 GTI years ago and that didn't hunt once set up right.

The bottom ends are solid as long as the compression is ok, there's no need to spend money on it in my opinion. Just keep up the oil changes.

Thanks gav i thought this post would have fired a little more of a debate.We will find out in the end ill post as i go but will have to be patient as p&p on the head is being done in a busy mans spare time so in time will tell..

Although with the time delay new pistons are tempting so is a two litre bottom end but cosidering mine is one of the only still in original form i will be leaving it that way.Still keen on opinions anyone???

I believe it can be set to idle half ok and drivable around town i may be wrong?

mate Golfworx no longer posts here unfortunately oneofthegreats is golfworx.

hopefully his build thread is here somewhere. His set up was mean, and went like a cut cat!

My advice is stick with the 1800 as long as you can. I fitted a 2 litre in my MK1. It did little to compliment the previously revvy nature of the motor.
The head had big valves as well as the cam and vernier. It was a much better drive as an 1800. The fuel consumption was crap after too. The 1800 would do 40MPG on a run. The 2litre struggled to do 30. The reason being the Kjet. To get the power at the top end you had to run it rich everywhere else. Same with the timing, well advanced to get the power, which impacted the tickover and part throttle.

It was crying out for electronic control now I look back.

The 1800 or maybe a 1900 would be a much better place to aim. A shame the 2 litres as so easy to get......

I agree Gav the 2 litre bottom end can feel a little slugish in comparison to an 1.8 litre due to the much greater weight of the rotating assembly, hence i knife edged my crank lightening and balancing it along the flywheel.
What are the first two letters on the engine blocks identification number? You can find out what its specs the engine is from that, such as valve size, compession ratio etc.
If your on a budget Jason i would stick with your 1.8 bottom end but consider a lightened and balanced flywheel. It makes quite a difference.. Match port your larger throttle body to the inlet manifold aswell.
I repositioned the airbox and k-jet system closer to the manifold on my MK2 GTI originally, it sat only 100mm from the throttle body and along with a 4" induction hose this showed a good gain.

Pretty sure Jasons engine is a DX.
It has 50ish miles on from new, so I reckon the bottom end is sound.
My only worry is the massive Cam on Kjet, but I gues we will find out.
