Guest lukey Posted December 12, 2007 I've just bought a turbo technics cionverted 1.9 gti... I'm taking her down to turbo technics in Northampton for blowing manifold gasket.. what are these guys like? Has anyone got any expereince of dealing with them and the work they do? Any info on the turbo technics conversion would be appreciated, cheers Lukey Share this post Link to post Share on other sites
ORB 227 1 Cars Posted December 12, 2007 I think you will find that the gasket is more than easy to swap yourself. Have a go, get your paws dirty! Share this post Link to post Share on other sites
Guest lukey Posted December 12, 2007 Yeah I know what u mean.. I thought about it.. u know what they say.. it the thought that counts lol. the turbo is in the way, old bolts might snap in the head.. and there shouldnt be a gasket there in the first place, turbo technics told be.

TEKNOPUG 3 Posted December 12, 2007 Are you 100% certain that it's blowing from the gasket; not the manifold itself or any of the studs lose? The reason that I say this is because as you have said, TT's shouldn't have a gasket. Which means at some time the manifold has already been off - most likely to work on the head. If a different head has been fitted, then it's almost certain that the exhausts stud holes weren't bored and tapped to accommodate M10 instead of M8 studs, leading to them being overtightened and failing due to the stress and the heat (snapping or stripping the thread) meaning that manifold will never seal properly and it'll blow…… Welcome to my world (ex)! Hey, maybe you even bought my old car…... Share this post Link to post Share on other sites
Guest lukey Posted December 13, 2007 I really dont know wheather or not the head has been done to fit the M10 bolts? gess i have to wait and see what the guys at turbo tecnics say.. any other info u can give me.. would be great ! thank you. Share this post Link to post Share on other sites
TEKNOPUG 3 Posted December 13, 2007 Post some pics up of the car and the engine bay and post as much info as you have. I'd be surprised if no one on the forum recognises the car - is it the grey one from Kensington that was on PH recently? I can’t diagnose problems via cyberspace really but I can tell you whether the work that the garage proposes is correct and whether there are other parts or work that should be done at the same time.

Guest lukey Posted December 13, 2007 Lol.. yes thats right! will get some pics up soon. Where in north London are you? im in enfield, Share this post Link to post Share on other sites
vern 0 Posted December 13, 2007 Am I reading this right that you do not use a gasket between the head and turbo manifold?, I only ask as I have put some in, but the head will be coming off soon, how worth while is it drilling out the holes to M10?. Share this post Link to post Share on other sites
TEKNOPUG 3 Posted December 13, 2007 There is no need to fit a gasket as it will seal perfectly without one provided that the two mating surfaces key wirth each (consider the amount of heat going through the manifold - it will seal). You can use a gasket from a Nissan (S13?) but I know that MadProf did that and they kept blowing - so pretty pointless I think. With the heat going through the manifold - a gasket would be the first part to fail. As to whether you need to fit M10 studs - TT did as part of the conversion and don’t think that they would have gone to the hassle and it expense if it wasn't necessary. Again, I think that it is to do with the heat and stress going through the head and also the torque that is required to seal the manifold to the head. Why are you taking the head off? For peace of mind, I'd send the head and manifold off to a decent machine shop (QEP etc) and get the exhaust side and manifold machined so they key perfectly. While your at it, get the exhaust ports and manifold inlets fettled so they match without any lips (you can polish the ports and runners yourself) then get the exhaust studs bored and tapped to take M10 studs. Saveloy has details of the studs to get, to ensure that they never work loose/snap/strip the thread - can’t remember off the top of my head but can try to find out if you like? Basically, do everything that needs to be done to ensure reliablity so that you avoid having to remove the head again - which can be a real PITA, what with head bolts snapping etc. Also, fit a Peugeot GrpN head gasket when refitting.

TEKNOPUG 3 Posted December 13, 2007 You may as well get new guides fitted and 3 angle seats cut whilst you're at it. I think I got quoted <£400 for all of the above work, including a head skim. Share this post Link to post Share on other sites
Guest lukey Posted December 13, 2007 Hpoefully the head will not have to come off!! thats worst case..if the bolts snap! yeah.. the gasket shouldnt be there. Share this post Link to post Share on other sites
vern 0 Posted December 13, 2007 The head is coming off as I have a big valve flowed one to go on, just spoken to matt at QEP who is doing the refurb and got him to drill and tap for M10 studs, on the end 2 studs. Share this post Link to post Share on other sites
TEKNOPUG 3 Posted December 13, 2007 Get all the studs done. Get him to key the exhaust & manifold faces to each other and also match the exhaust/manifold ports. Matt gave me the quote above. I'll chase Kyri for specs for the studs. Share this post Link to post Share on other sites
vern 0 Posted December 13, 2007 Unfortunatly will not be able to match ports etc as manifolds are still on car. The head is one I got second hand and just having a refresh done. Spoke to Matt and he said only to do the end 2. Have all ready sent a PM to Saveloy for the stud details. Share this post Link to post Share on other sites

saveloy 8 Posted January 7, 2008 You mean the end 4. Simply because it is the outer ones that take the most strain, so they need larger studs/nuts to take the increased load. Share this post Link to post Share on other sites
