Header: inverted


6/19/6

Ya ya, it's the 4th design we've made.  So far each has been totally different.  In this design there was no goal for equal or even near equal length runners but just to make a turbo hang upside-down.  This was made with an external wastegate in mind.  There was the problem of the oil filter and the adapter, the power steering lines and one A/C line.  First we thought ok, that filter can get moved, the power steering lines can be moved and no there is no A/C on Kurt's car anyway so this can work.  No this isn't Kurt's car tore apart again it's one of my 88 automatics.  Still haven't found stainless in straight pipe but we haven't tried any plumbing stores in Indianapolis, local suppliers said they should have some.  The outlets here don't carry stainless anything.  The Els are still the ebay ones, the collector was pre-welded and the flanges were cut locally.  It might be hard to see, but by rotating the collector 45 degrees we now have plenty of room to bolt the DSM turbine flange one with bolts instead of washers/nuts/studs like we did before.  The larger straight tube is where the external wastegate will attach and point rearward incase it is desired to dump that into the downpipe although Kurt seems to favor an open dump for a little more drama...

The inner runners are the same length and the outers are very close but we didn't try to make the inners match the outers. 

This is actually a prepped ready to assemble bored and blasted block but hey, you have to fit the parts.  The head is junk and sits on a used gasket to keep the deck safe.  The valve cover was from this car.  Factory exhaust is still on it. 

Ok, the orange tape measure is how far out the filter sits with the adapter on the block so you can still change the oil and do this setup.

It also works using a larger compressor housing.  We tested one that is the large one used on a 20G and it too fits.

The downpipe will first point inboard and the next transition with point downward and then we'll use the same setup for the downpipe flange connection we have used before so you don't have to get under the car to change anything.

So you are asking what about the power steering lines?  We have fittings and braided lines and will run those on the intake side and across the radiator support and then to the pump/cooler/reservoir so they won't see any turbine housing heat.  The header will be wrapped and probably a heat shield made for the plug wires and that brake line for the right front caliper or we might just relocate the line into the wheel well from a different spot.

more welding, right click save or just mouse over to play

below left 20G housing below inlet ported by Forced Performance

on right below, the DSM housings are threaded, the bolts for that will all easily be tightened from the top (like they do on a DSM)

below left, ported out DSM housing, possibly for an 18G I forget and a extreme ported stock C/S

housing below on the right that is fit over a 20G compressor wheel, and you didn't think a stock

housing would port out that much did ya? :)

below this is a Greddy 20G housing, the oil filter is easily removable, even easier than in a stock setup.

Greddy used mitsu parts and then modded them or made changes and hybrids and made them better

using different combinations of parts

This is the orientation of the 19C that will be on the car in the end, the "J" pipe will rotate to the front with the compressor-out going straight from that J-pipe through the radiator support, 90 degrees down the the intercooler, and the return pipe from the intercooler will run out the right side above the hot side pipe then connect the the OVCP.

The header WILL get ceramic coating after all and it will also be wrapped.  That won't be happening

until the external wastegate is in and the downpipe is made.  Some new heat shields will be made and a brace

from the engine mount up to the header for added support.
