Acid Chemical Dipping a Renault 5 GTT Engine & Skimming the Cylinder

[@jamesdecross1035]

That's a job I must do with my Saab. It looks amazing!

[@Renault5Rebuild]

Thanks! Honestly the process and change is amazing.

[@alanspittle6728]

Look amazing Greg…. Shame about the turbo:-(

[@Renault5Rebuild]

Yeah… oh well! Just another hurdle to jump! 😃

[@mattcole6230]

If that head didn't need skimming then it shouldn't have been! Unfortunately the C1J turbos are particularly sensitive to compression changes, something you will need to consider when rebuilding and fueling.

[@Renault5Rebuild]

The head wasn’t 100% flat, it did take 4 cuts and I want to ensure a perfect seal. Thanks for the advice regarding the fueling. 👌

[@mattcole6230]

@Renault5Rebuild OK. Worth calculating your new compression ratio, then consider boost target and carb set up. Good luck

@@Renault5Rebuild Boost will need to be lower now. Back when these were popular i used to do SAAB APC conversions on R5 GTT's, since the SAAB Automatic Performance Control system is a separate system on early classic 900 models and can be removed and transplanted to other cars. Giving you a computer controlled Turbo with effective Knock control and boost reduction to save the engine from knock. Paul @ The SAAB Clinic UK.

[@Renault5Rebuild]

Will do, thanks for your advice.

[@Renault5Rebuild]

Nice! Will have to have a look at that

Im guessing thats actual matt black engine paint and not just a can of matt black? Engine paint is rated for temperature and chemical spills..

[@Renault5Rebuild]

Indeed it is.

Hope you enjoyed the video! Do we do any upgrades to the engine whilst it’s in this state?? For all your engine needs here are MJAs details: www.mja-engineering.co.uk/

When you say "cracked turbo", all I hear is "opportunity for upgraded turbo".
