Abit too late now with the gasket. I have a headstud kit I'll be using so hopefully that will help.
Will keep an eye on it, if it doesn't seal I'll use an oem one, thanks for the heads up though. Could save me some hassle trying to diagnose issues further down the line.
Fingers crossed they've fixed there issues and make decent gaskets now lol
Romain did mention a ram horn style manifold would help bring it further down. Really don't want to be faffing around with exhaust manifold cracks etc that seems to be quite common on those types of manifold. I was very happy with how the car performed before the engine went so I'm sure I'll be happy this time regardless.
If you get a good quality ramhorn manifold it shouldn't be prone to cracking. The thing people some times over look is that unless you have a flexi pipe/joint on your downpipe a lot of stress is been exerted on the manifold every time the engine moves! So make sure a flexi pipe/joint is incorporated into your downpipe.
At 300hp+ you could pick up +15bhp at the same boost level by switching from your current manifold to a good quality ramhorn, we seen almost 30bhp on a 380bhp turbo b18 when switching from a log style mani to a ramhorn. I have a Go-Autworks ramhorn and GT3076R turbo fitted to a stock b18c4 with type r cams, it has a nice wall of torque from 5300-8600rpm, vtec point occurs at 4000rpm, during spool which does indeed reduce the time it takes for the turbo to reach full boost. If I had of used a smaller A/R exhaust housing I could have reduced the spool time further but for this application we were after topend power.
