cor 80 Posted March 11, 2009 Report Share Posted March 11, 2009 Hello, Lotus has an offer on the turbo HC piston and liners for the HC turbo esprit. If i take it correctly they would fit an 1988 stevens turbo esprit. The car has a chargecooler which was added later. Can i expect any problems fitting these piston/liners?? Thanks Cor Quote Link to post Share on other sites
ozontour 0 Posted March 11, 2009 Report Share Posted March 11, 2009 Am sure they are the same part mate... the same as i put in my 88 US Spec turbo. somebody might correct me but am pretty sure.

Simon350S 192 Posted March 12, 2009 Report Share Posted March 12, 2009 Pistons are exactly the same as far as I'm aware appart from a coating on the piston crown of the SE versions. Quote Chunky Lover Link to post Share on other sites
Vulcan Grey 257 Posted March 12, 2009 Report Share Posted March 12, 2009 The SE chargecooled pistons have different cutouts for the valves. IIRC the comression ratio is lower on the SE as well... 8.5:1 I think.

rocket63 137 Posted March 12, 2009 Report Share Posted March 12, 2009 Make you right there Travis.

Simon350S 192 Posted March 12, 2009 Report Share Posted March 12, 2009 God darn it! I've got SE pistons to fit, so no high compression hopes for me Still slightly more than standard I guess but they are much stronger than the originals which was my only real reason for getting them Quote Chunky Lover Link to post Share on other sites
Vulcan Grey 257 Posted March 13, 2009 Report Share Posted March 13, 2009 Simon... add a charge cooler and increase the boost... there's your solution Quote Travis Vulcan Grey 89SE My Lotus Photo and Projects Album Link to post Share on other sites
watership down 0 Posted June 27, 2014 Report Share Posted June 27, 2014 Can anyone advise what type of Hylomar I must use for the piston liner? Quote Link to post Share on other sites
Vulcan Grey 257 Posted June 28, 2014 Report Share Posted June 28, 2014 I used the blue Hylomar HPF. Looks like Hylomar "M" is the new version of HPF. Quote Travis Vulcan Grey 89SE My Lotus Photo and Projects Album Link to post Share on other sites
910Esprit 577 Posted June 28, 2014 Report Share Posted June 28, 2014 Loctite 572, however check with a specialist (or a dealer!) Blue Hylomar is a flange sealant so it seems a risky choice for this application and would always require liner clamps for any headwork. I would stick to a suitable anaerobic.

Vulcan Grey 257 Posted June 28, 2014 Report Share Posted June 28, 2014 I would say that the cylinder liners are a flange sealing situation. Loctite 572, as an anaerobic, begins to cure right away, which means there's a chance you can disturb the seal as the rest of the engine is assembled.. The Loctite 572 TDS actually calls it a thread sealant... Not a flange sealant. The Hylomar "M" or RacingFormula (same as Permatex HPF) is what many of us use. It never sets, and won't get disturbed during assembly, by vibration or thermal expansion... The V8 guys use Hylomar 3400, which is also an anaerobic sealant. Hylomar has some other formulations, like the Hylomar Advanced TDS does say cylinder liner sealant, but it has no film strength and relies on the machining surface finish and a really good fit. It isn't as forgiving of the assembly variances. Read the TDS here http://www.hylomarsealant.com/_resources/_html/products.html The Blue Hylomar is not easily disturbed, in fact you can pull the liners out and put them back in again without the need to reapply the sealant.

910Esprit 577 Posted June 28, 2014 Report Share Posted June 28, 2014 not my definition of a flange! My worry with Hylomar Blue would be that the liners could fret in high power applications, but if it works for you that's fine. However, I'll be sticking with the Lotus recommendation.

Vulcan Grey 257 Posted June 28, 2014 Report Share Posted June 28, 2014 Hylomar Blue is what they use on drag racers... Loctite 572 is probably fine, it was for 20+ years on most Esprits. They had issues with it on the V8. WHen I took my 89SE apart the first time it did not have Loctite 572, Lotus didn't specify that until '93. My engine probably had the Hylomar PL32 (starting with the 907). My cylinders were definitely in with a non-hardening sealant, rather than an anaerobic.

Simon350S 192 Posted June 29, 2014 Report Share Posted June 29, 2014 not my definition of a flange! I may regret this question... So, um, what's your definition of a flange? Quote Chunky Lover Link to post Share on other sites
Mike6 11 Posted July 3, 2014 Report Share Posted July 3, 2014 I fitted SE pistons and liners to my 88 Carb turbo. The pistons do have a slightly different crown profile and are chrome plated. I was advised by a renowned Esprit expert that it would be an upgrade to the earlier piston. Certainly seems to work ok. Quote Link to post Share on other sites
