Turbo Technics Valve Clearances

[Mad Professor 7]

Hi All.

 

Can anyone please tell me if the 1.9 Turbo Technics Valve Clearances are the same as standard 1.9 GTi valve clearances?

As far as I am aware turbo technics did not adjust anything top end of the engine.

 

The old joke book has the following details for the standard 1.9 GTi.

Inlet: 0.15 to 0.25 mm

Exhaust: 0.35 to 0.45 mm

 

So would this mean in an ideal world that it would be.

Inlet: 0.20mm

Exhaust: 0.40mm

 

Thanks.

I've never heard of TT changing the valve clearances.

 

Dave baker (pumaracing) recommends:

 

Inlet: 0.20 to 0.25 mm

Exhaust: 0.30 to 0.35 mm

[Mad Professor 7]

Ok thanks.

 

I am tring to get rid or at least lower the top end rattles.

I have now fitted knock sensor for use with my MegaSquirt ECU, and it is just picking up on engine noise to much.

 

I will get out to the car as soon as the sun comes out.

OK reading from left to right.

 

Exhaust - 0.011(in) 0.2794(mm).

Inlet - 0.007(in) 0.1778(mm).

Inlet - 0.005(in) 0.127(mm).

Exhaust - 0.016(in) 0.4064(mm).

Exhaust - 0.012(in) 0.3048(mm).

Inlet - 0.005(in) 0.127(mm).

Inlet - 0.1524(in) 0.1524(mm).

Exhaust - 0.016(in) 0.4064(mm).

Thats the problem with those sensors... Not really needed if mapped correctly though.

[Mad Professor 7]

She not yet maped witch is part of the resign why I have the knock sensor all fitted now, to aid with the tuning and mapping of the ecu.

[Mad Professor 7]

Also I forgot to add that I am running GTX 10w40 oil atm.

joining the topic

is it still possible to get turbo technics new parts? as i heard they stopped selling!?!?

im not local, but i've got a TT kit around, but interior engine parts are missing. is it possible to get it ?

cheers.

Worth doing in the search for a quieter valvetrain then!

 

srack: Is it just the pistons you need? If so you can just get some dished to suit. TT will do this for about £130 but want the old ones as a template (which you get back too). Since you don't have these you can either find someone with some lying about, get an engine builder to do it without a template, reducing compression ratio to 8.6:1. Or buy some from http://www.hiflowheads.co.uk second hand.

[saveloy 8]

Proff, most of the clearance figures can be attributed to carbon build up on the valve seats. Bear that in mind.

[Mad Professor 7]

saveloy: Fair point.

 

How long does it normaly take to get carbon build up on the valve seats.

 

I have also been thinking about chnaging oil grade, I have always run GTX 10w40 with the turbo.

 

What grade do you peps think I should use or should I just stick with the GTX 10w40?

[richard 0]

Depends on how you drive it!

 

Personally i'd run something like mobil1 or equivelant...remember this isnt a std TT...so you'll have even more heat build up. Destroying the oils properties much quicker.

[Mad Professor 7]

It's a 205 TT how do you think I drive it

 

So are you saying stick with the same grade but just change the make?

[pdd144c 0]

Dont use anything other than mineral oil! I found the Valvoline Turbo stuff and Valvoline Racing the best oils.

 

If you'd had a TT Richard you'd know that

[TEKNOPUG 3]

I disagree - use the best fully-synth that you can afford - the Pug internals may appreciate mineral but the temps that you are going to be running in your turbo, you really need full-synth. Sylkoline Pro-S for example.

 

With regards to your valve clearances - you don't have a "standard" 1.9 head though?! I thought that you had some Stage 4, big valve, Hi-Flow job??

[Mad Professor 7]

Yes the head is a HighFlow jobby.

 

I have e-mailed them regarding valve clearances for this head, but as of yet not heard back.

The Vavoline stuff can handle those temps Andy.

[Mad Professor 7]

Bring up an oldish post.

 

I spoke to highflowheads regarding the Valve Clearances thay said it would be the same as stock.

 

Witch as stated above is.

 

Inlet: 0.15 - 0.25mm

Exhaust: 0.35 - 0.45mm

 

I have been speaking to Alan Jeffery, and he seems to think to give the exhaust a Clearance of 0.30mm.

 

So if eveyone thinks it will be ok I would like to reshim my engine to give me the following clearances.

 

Inlet: 0.15mm

Exhaust: 0.30mm

 

What do you think?

i found mobil 1 and castrol rs just too thin, even on a rebuilt engine made it a bit noisy, I now just semi-sinthetic and change every 1500-2000 miles
