Turbo charging my RE2500?

[MGaz]

Forged stroker crank! Should have said repo, sold my RE2500 engine start of the year for £300.....

out of interest, who bought it? :mischeif:

Are they keeping it as it is? or braking it for the chrome molly stroker crank?

[MGaz]

its high compression so no.

power is all about flow. the design of the head is not great. mounting the turbo and inlet on the same size has manifold and turbo implications.

ower delivery also suffers. 2v tends to generate on/off switch cars. combustion chamber design doesn't help with detonation.

id expect a mildly tuned 16v engines to be as good as the 2.5 RE engine for performance.

could I fit a 20v head to the engine? retaining the 2.5 stroke and my forged pistons?

yes, its done on motorgeek few times 10v bottom end and 7a head gets compression down for turboing. works because the 10v has dished pistons, you might need check for clearance on your setup make sure pistons and valves dont clash, but no reason why should.
you would also need either weld the head or block however block of part the oil return like on doing a diesel stroker, no big hassle

my engine is also bored out slightly so that the 2.5L isn't created entirely with a long stroke.

Would it still be suitable?

Also, once the 7A head was fitted, would 20vt parts just bolt strait on? IM, EM, ECU, coilpacks etc?

or would I need expensive custom 7A turbo parts?

the pistons will work but ideally need swapping for proper ones.

also need to check things like how the ndizzy works and if there is an intermediate shaft. im not up on the 2.5 5.

id just sell it and get a full I5 T
