sweet guide,
Only bit I'm confused about as regards using a R400 GSI (non turbo T series) as a donor car is that can that engine be easily converted into a turbo lump? If so what parts are needed?

Technically yes, i believe the differences are the pistons, rods, cams , oil outlet in the block for the turbo, sump pan (oil return for the turbo) engine wise. It mounts exactly the same etc! They are the same externally and its only the turbo that gives it away, but there are differences beneath.

Thanks for the reply
Hm so really if using a 400 as a donor car the only bits needed from it are the engine mounts and wiring loom? (from reading your guide)
Also when dropping it into a ZS I presume the ZS would have to been a 180 originally or else some of the parts already on the ZS won't work if it started off life as a K engined ZS (driveshafts etc)
Sorry for all the questions, just very serious about doing this conversion and trying to figure out the best way to go about it all

the only parts you would need are pistons (get some forged while its out) and the sump. the later blocks have the oil feed in the block, its got a blank in it.
everything else is the same/can be used.

thats in the 230bhp section. there is no uprated gasket and head studs are generally needed for over 18psi as it lifts the head. id put that in the 300+bracket.

porting adds power all over the rev range, its not as good on a turbo as a nasp as the air is forced in but its said to be 15% gain on a nasp and 5% gain on a turbo.
ive not seen anyone with an aftermarket inlet manifold (except myself ![Wink](http://www.themgzs.co.uk/vb/images/smilies/wink.gif) ). most use an M series inlet with the throttle body re-positioned to open the restrictive part of the manifold.
