Here's a pic of the "new" engine....it's been in and running for about 2 months now, but has a leaky head stud. Good thing too...it'll give me an excuse to pull the old 302 heads and put the new 351w ported heads on! parts list: '93 302 block, stock std. crank, stock rods with new arp bolts, JE/SRP forged lightweight dished pistons (8.2:1), lightweight tapered wristpins, C&A 1/16" rings, FRPP windage tray (lowers oil temps by 30 degrees!), '68 302 truck heads w/ 3/8" screw in studs/guideplates, hardened pushrods, Erson Hyd. Roller camshaft (almost stock!), "blueprinted" stock Ford Duraspark dizzy 15 deg. initial, 30 total @ 3400, Edelbrock Performer RPM intake manifold w/4779 600 cfm Holley DP (modified for turbo use), home-made 1 1/2" headers, etc. here's a link: http://www.geocities.com/mavman687/bym.htm
looks good! i noticed you re-routed your fuel line since the last time... was kinda wondering about the fuel filter near the turbine b4... thought that would be kinda hot. But I guess thats problems solved now. Anyhow ever think of putting an intercooler on for cooling along with a blow off valve for controled boost as well as a turbo timer to let the turbine cool down? Cuz some of the new tech they have out there for turbos are awsome. Being in the import market I know turbos can really kick some but if done correctly just some of the new tech out there really is what makes these these turbo cars run awsome. I have a couple of buddies what run RB25's (thats a Nissan Skyline Motor... ok... bad word)with a Turbo putting down some killer hp numbers driving them every day and laying down a mid 10 sec 1/4.... more then my car will ever do. But just a thought... theres never harm into looking into new thingys. Also i notice you said you have some hose blow off wasn't too sure which ones you were talking about. You might want to look into Turbo Hose Couplings (see pics below) They can take the heat way better then rubber and the clamps are way more user friendly. My buddies use these they are running about 25 to 30 lbs of boost and they hold up! Anyhow just some thought that might help you out. But nice job and keep up the good work.
thanks for all the info. I've got a wastegate around here somewhere that I'll add later, but I'll have to but a BOV. One of these days, I'll also have to look into the silicone hose connections too, as I've already blown out one of the cheapies (backfire..lol). Intercooler? it was a thought....but where in god's green earth would I fit it on the front of this thing? There's absolutely no more room for it! Besides, at only 10 psi, it would only be worth probably 20 HP or so, not really much of a gain considering the cost and trouble. Thoughts on the "turbo timer", yea I've seen them...but with this turbo which is a bit big, all you have to do is let it idle for a minute after a hard run (the turbine barely spins at 700 rpm, so slowly that I can stop it with one finger) it should be plenty. Besides that, the Powerstrokes dont have anything like that...and they whine pretty good at idle speed. I will however have to change the turbine wheel someday, as when the other engine blew, pieces of piston were thrown through the turbine and bent one blade pretty good. That's later on though...right now, I'm concentrating on selling my truck, and getting the other mav back together...lol
