I'm building a turbo M42 with a small budget for my race car. I'm going to use as much OEM part as possible. Race series technical rules dictates 34mm intake air resrictor so I'am aiming to 300whp and +500nm of torque. I will use E85 as fuel so I can use high compression ratio(about 10:1) and boost(1,5-2bar) to achieve to torque figurs with 3000-6000rpm power band.
My plan is:
-M42 block bored to 86mm(400000km original engine)*
-M47 88mm stroke forged crankshaft*
-ACL Race main and conrod bearings
-No-name forged H-beam M50 135mm conrods wit ARP bolts, upper bearing changed in machine shop to 21mm
-2nd hand S50B32 pistons*
- M44 MLS head gasket
-ARP head studs
-Stock head and cams* with new hydraulic buckets, valves and springs
-S50B32 ITBs* and shortened oem plenum* with modified 2,5" inlet for boost tube and blow of valve
-1000cc ethanol injectors
-Big 2,5" intercooler at front
-Mitsubishi EVO3 oem turbo with 34mm inlet restrictor
-Modified M42(e30) exhaust manifold* inverted for front mounted turbo installation
-3" downpipe/straight exhaust with side exhaust behind drivers door
-DTA S80 ecu* with full custom harness and sensors(inc. ethanol-sensor and electric boost control)
-Porsche coil on plug-coils
-PWM waterpump without termostat, ECU controlled
-Lightened M20 flywheel and sintered clutch
-E36 328i trans(5-speed 320z)
-Typ188 3.23>2.93(240km/h tops)>2.65(265km/h tops) 75% race spec LSD
I already have parts marked with *
My car is:
-1990 318iS with 400kkm on dash
-Heavily lightened M3 glassfiber body(pun intended :)
-FIA 8-point cage
-DTM-style front tube suspension
-Adjustable oem rear axle
-Group N spec Bilstein E30M3 shocks with coil over springs
-Porsche Boxter 4-pot calipers with E46 300mm discs and floormounted pedalbox
-Plexiglass windows
-GT3 carbonfiber rear wing
-Large front splitter
-245/45R17 Toyo R888r semi-slicks on lightweigth forged wheels
-900-950kg without driver(who weights wayyy too much :)
Is there something that I need to re-think with my intended engine build? My first turbo build so I'm not so familiar with turbo technics. Sorry for the typos, english isn't my native language :)
Ps. I'll post picture of my car when I get to computer later
