Hi I am bob from north scotland uk
I am looking around your excellent site as although I do not have a Miata I do have a 1.8 engine with a turbo and information on small engines with aftermarket home build turbo's is quite scarce
I found this site after searching for information on the Garrett GT2854R as thats what I have remote fitted to a S1 elise. The engine ( a rover k series ) is home custom built with paulter rods , ross pistons ,plx wide band dta ecu custom exhaust with sports cat , charge cooled and a small smic
I do not want a lot off boost. I intend to start with 5 psi and increase up to a max of 10 psi because I am running a high c/r and very close piston to head / valve tollerance ( excuse spelling )

It has moved on a bit from here ,I now have the oil scavenge sorted with a weldon pump and the engine runs, I am now down to final finnish details

 

Welcome to the site, sounds like you're piecing together a nice little car.

 

I spotted this dude while I was in Holyrood Park (taking a **** just off the trail) a few years back:



That thing sounded amazing.

 

thanks pdexta
wish I had not started ( sort one problem only to find the next ) but in it too deep now but yes it should be good
pusha
that one is an S2 exige it has the toyota engine and I expect supercharged its about 930 kg
my S1 is approx 730kg but nowhere as refined

 

Welcome to the sight.

 

thanks I am learning a lot from here , its a wealth of information on this site
