Hello all,
Got a MK1 caddy which hes been chopped up, and am hoping to start on re-building the engine soon.
It's a 1.9TDi with a land rover fuel pump (still needs the bracket modifying, and figure out how the hell to put a new sprocket on etc), .240 or .260 nozzles, FMIC, 2.5" straight through, and a GT2052V turbo.
Problem is, I've been advised to use a direct actuated brake servo, which for us RHD cars puts it right behind the engine
Would rather not use a linkage and move it over to the other side due to being a pretty beefy system (11" discs, 4 pot calipers, 9" servo and 22mm M/C)
SO, in order to make some space back there, and in the name of a more efficient engine, i'll be looking at something like a 1X manifold, or a modified D24 intake, but the exhaust is looking like a custom job
I chopped the flanges off an old manifold, these will be port matched to the head.
I can get hold of weld elbows, although not very thick walled
1. does it matter if the header pipes are of equal lengths, like on N/A's, or should the aim be to just get the gas to the turbo as quickly as possible?
2. does the order in which it enters the turbo really matter? i read it somewhere
3. would i be better off just using a log style exhaust manifold to get the gasses straight to the turbo (simple, pretty efficient i imagine), or individual pipes and a collector at the turbo flange?
Some photos for reference
thats with a slightly better than stock intake, and a 4 bolt manifold (would still need an adaptor)
a possibly kind of design for the exhaust? (it's the inlet on an old Massey Ferguson MF35, but it's the shape that matters :p)
sketch of the exhaust header. this will put the turbo on the right of the engine, out of the way, but also easier for routing the stainless tubing for the IC
Thoughts, opinions, criticism, all welcomed
Regards
-Henk
PS, is there any reason why I couldn't have a bare engine block shotblasted?
