you can easily get your compression to 7:7:1 if you want to with p & p, 1.8 cam, 1.8 ecu and a few other things. I think caj darkmoon or someone did a DIY for doing your own P&P work. It really is mostly time with a dremel tool and sandpaper and since you pulled your own engine I would think you could do it yourself.

Running 20-25 PSI is high on a Beta 1 engine. You can find several tibs on RDT running high PSI on stock engines. Most seem to run in the 16-17 range on stock compression but some test the waters with higher numbers. I don't believe there are many that boost over 20 regularly.

 

i'd rather a professional port and polish it for me, since i've read if you don't do it the right way it'll have a negative effect rather a positive one.

 

theres a guy here in Aus with a built LC2 thats running 22psi on a garret turbo and an external wastegate
think its got forgies in it to around 8:1 compression
makes about 220hp if i remember rightly - best 1.4 mile of 12.8

 

hey your just gonna do the 1/4 mile right? i dont know what psi this guys is running but he makes 9.42 @ 142MPH in his accent! found it on youtube and thought you might like to see it.

^^ That Accent is pushing 500hp awd and it isn't a beta engine it's a Mits I believe and completely stripped.
