Been working on my turbo project for multiple months now. Got it running for a few weeks before I decided to give her a little more boost.
This was the result...
So 17psi was the limit of the stock head gasket with my tuning setup at least. Next up was to pull the head and replace the gasket.
Pulled head/intake manifold/exhaust manifold/wastegate/downpipe all as one, seemed much easier.
Pistons looked great, gasket did not!
All buttoned up!
After I put her all back together I turned the boost back down to 8psi. Its still tons of fun especially in the rain. Still an ongoing project as this is a pretty cheap/homemade setup. Comments and criticism welcome as always.
Specs:
M20B25 (stock internals)
Metric Blue headbolts
Stock Goetze headgasket
Modified early ebay manifold
Tial knockoff wastegate (5psi spring)
Knockoff boost controller
Holset Hx35 (open downpipe)
Ebay intercooler
Custom charge pipes
Motronic 1.3 with timing retard chip
M30 AFM
Begi 2025 RRFPR
AEM wideband
