This thread will be dedicated to my project long in the waiting. Alot of research. Alot of new ground work. A few performance forums attributed to get this far. An excellent workshop found also. Big thanks to Roman (Pumpish) who is nothing short of an inspiration with 300E's & their terribly under-rated performance potentials.
To begin with. Bought this 300E in January of this year from a disillusioned seller who had a pathetic workshop build the car. The poor workmanship & little knowledge put into the build led to the destruction of the performance built engine along with, most of the running gear including turbo. So. Most of the running gear needs to be replaced from scratch.
Hope this thread will be informative & maybe stir a little discussion for those interested in stretching the boundaries a bit
Purchased items & work to be done & recently commenced:
Low km M103 3.0L in VG cond' left stock 9.2:1 comp
(aid in spool time)
GT3540R .84 A/R billet comp wheel; ceramic bearings (all lowering spool time)
Microtech MT8 timing only ECU
3" turbo back mandrel exhaust
Larger FMIC & fabricated mandrel aluminium piping to suit
Custom Inlet inc 3" bell end runners & Boxy Plenum
Custom Steampipe Exhaust Manifold with 45mm external wastegate
Reco'd 400 Mixer (older style is better) & Twin Vapour/Convertors & larger lines to suit
Rebuilt Trans with shift kit & 2300rpm stall convertor
New engine Mounts
New Trans Mount
New Behl Radiator & all hoses
New Front Flex Plate......will add later any other gear I've forgotten
Boost will begin @ 10psi, then 12, then hopefully 14
Will be installing LPG primer sensor & oil filter between engine & turbo
Looking realistically @ between 260-290rwkw depending on boost I run?
Decided to raise the boost in increments when we, eventually do get to tune car Initially do a run @ 10psi using a 45mm external wastegate then @ 15psi @ see how she fairs & what hp we can achieve @ this boost. As I've said before, hp will be down due to small turbine housing but the trade off is quicker low down response so I can live with that
Also the larger comp wheel ensure large volume of airflow & counter the back pressure anyway. All in the set up @ this stage.
Also @ this stage I think I'll call it a day @ 15psi for reliability purposes more than anything. The LPG will work in my advantage in this area with it's higher octane ability however, this hp will be a big enough shock I think for the stock car including running gear, brakes, suspension per se.
The MT8 has to be made up especially & will be a few weeks wait bugger it. Hopefully there is enough to be done in the meantime with fabrication anyway?
May try 20psi but only once I see how car handles the bolt-ons first?
Below are some pics of the car when I brought her home in January. It was running LPG set up with only 1 convertor. Running a Garrett T03 highflowed to T04 specs. Pretty stock exhaust manifold I think off a diesel? Not sure now. Exhaust was anywhere from 2/14"-3" ike a dogs breakfast. All looked good but it was destined to blow up.......it did!
