my 2 pence.
Stock engines internal with supporting mods and decent tune can and will run big boost.
But it will fail at somepoint if abused, same goes for some dogs b0ll0x engine!! it Murphys law
, what can go wrong will go wrong.
Its called pirmid effect.
the more power you give a engine the longevety will go down if you make massive power all the time.
Its not a BHP number that will kill a engine its a detonation theshhold, exceed that and any engine is dead you could have the bestest strongest block
, but it could be killed a number of things letting go.
I know a man that holds the UK record for 1/4 mile for Renault 5 GTTs, this engine in its NA form produces 70 to 80 HP
(turbo form 120BHP)
This engine dates back to 1940s(block pistons and head!!) its a push rod
, carb fed engine 8v with a crap head bad inlet manafold and exhasut manfold, has no piston oil sprays nothing fancy.
Now in the R5 world its laden with as much mis information as the Mr2 world and most other car clubs.
its all hear say.
The engine in the car in question runs 11.4 standing 1/4 miles and is road leagal.
in the last year its has done over 200 1/4 runs on the same engine.
This engine runs stock Pistons, crank,oil pump,oil cooler, its been blueprinted and put together correctly.
It runs a GT28r RB turbo
, at
2.5bar!!!! its head and exhaust manfold have been gasflowed and matched.
Now it has no fancy managment or EFI, it still runs a Solex DIS 32 Carb for fueling and still has stock distributor and stock leads.
It makes 290HP at the wheels.
Now my point is that on a well put together and setup engine as bad as the C1J and as dated as it is you can do things that will take abuse if setup right.
With the fact that the 3SGTE is a far more advanced engine and with far more advanced 21century forms of engien managment and ignition and cooling options theres is no reason that you cant do it right.
Sticking in Forges just to hide bad tuning that has killed a stock lump is a mistake.
With Forges the tuner should be able to suppass and tune the engine even more before it reaches the point of BOMBING out( with supporting mods) at the moment to me at least Forges seem to be a easy answer to bad tuning.
Im not sayign Im right and others are wrong, but being around turboed motors for nearly 10years I have seen alot of bad information rear its head and people just lap it up cos they dont think or check things out for themselfs.
