Making an obsolete engine relevant again.

Post by dfarr67 »

Just a general question- adding boost to an under achiever (Toy 22RE), 115hp to 180-200hp lower rev range. Is it still a POS or does boost give an old type engine a new lease on life. Too late for this project now I am committed- but always wondered whether I should have chose a newer power plant. To qualify a little bit- turbo ready build, efi with good injectors and a modern type ecu.

It can plenty of power if tuned properly and the right size charger you can at bare minimum double the power output

You call that obsolete? Those are still in used daily in some parts, and all parts are available.
the 18R is perhaps obsolete

Turbo should work fine, inter-cooled I assume. Icon has some interesting pistons for that, might fit what your doing or might not.

Short block traded for, was turbo ready with dished pistons. I guess I am thinking of port and chamber contributions to power these days. Ignition is LS CNP, on board WB and knock. Was thinking meth inj- but if the tune is good (conservative- think 4x4) I'd rather not have to deal with reliability concerns. Log turbo manifold so no high rpm operation, I cleaned up the runners and did some chamber work, upsized the valves, small CC cam- exhaust deshrouded and if the head comes off- the intake will be done too. I preferred to work with the platform over shoe horning an inline six in or a (once available complete) oem MR2 turbo engine, 4.8 LS, or 4.3 Toy- if it had a 3.slow- different story. This has a 5spd now- but when it was auto- it was a slug in the mountains. Turbo is a question mark- I know a bit more about them now but the manifold is firmly in the KKK footprint.
