HC piston+liners in turbo se esprit


Recommended Posts

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

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. (Don't have the manual with me now)

Make you right there Travis. Charge cooled compression ratio at 8.0:1

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.

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.

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.

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.

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.
