I want to set up a single turbo on my maverick with a 1969 302, do I need to have lower compression I believe it's 9:5:1 stock and what is the average cost for a decent turbo setup and what other changes will I need to make, thanks guys
Hmm can of worms here. I'm sure others will chime in that are more knowlegable.... Compression is all relative to how much boost you want to make.. Better head gaskets.... ARP head studs..... Blow through carb..... Carb hat...... Intercooler and piping..... Cost of the turbo itself...... Tuning...... Colder plugs....... Wastegate....... Turbo manifold....... Hope your pockets are deeper then mine Lmao.
9.5:1 compression should be fine at lower boost. Decent turbo: $750 Carb hat: $200 Hot and cold side piping: $700 Fuel system: $600 Blow through carb: $800 (you can modify a mech secondary holley for a lot less $$) Msd boost timing master: $300 (or you can lock your timing for free but have worse driveability) will also need a good electronic distributor if you don't already have one Intercooler: $350 for a cheap one (optional) Oil lines (an fittings and braided hose): $100 Wide band for tuning $250 Waste gate: $370 do not cheap out on this BOV: $250 Boost Guage: $30 for a cheap one Heat tape: $100 (optional but highly recommended) Total cost: $ 4800 These are all rough price estimates, but I don't think you can get it done for much less than $4000 if starting from scratch. Also no turbo kits are available for a maverick, all will need fabricated. You can also save a lot by buying used parts. There's a few other little odd and ends I'm forgetting. And as for head gaskets use felt pro 9333pt-1 the are cheap and hold up to boost well if your head aren't junk like mine were.
Thank you that helps a lot, what are your suggestions to get the most horsepower out of a 302, I was thinking of stroking it or saving up for a turbo set up being I haven't seen many and it would be unique
a good set of aluminum heads and all the matching stuff like intake, carb, cam, exhaust, and all the little things to put it all together. you should be able to get around 400hp with the right parts on that 302 block. heres what i would use. afr 185 cylinderheads. edelbrock perfromer rpm air gap intake holley 650 double pumper trick flow stage 2 hydraulic roller cam shaft link bar roller lifters hardened push rods roller rocker arms hooker long tube headers and the little things to put it all together are: air filter carb studs throttle cable bracket intake manifold bolts thermostat housing thermostat intake gaskets. head bolts head gaskets. valve cover gaskets. some pipe plugs may be needed spark plugs oil coolant. when i add it all up with estimated prices i get $4000.00 i firmly belive that that combination will make over 400 hp at the crank on your motor. another good thing is that all those parts can be transfered to a stroker motor down the road. going to a stroker wont make much more horse power but will make more torque and do the power and torque at a lower rpm.
There is some good info here. http://forums.corral.net/forums/turbochargers/1158492-best-single-turbo-stock-302-windsor.html http://www.theturboforums.com/forum.php?s=eaebcb1e69e5a00c98a7d7fc91a68db1
This also has my attention, particularly since there is a low mile M112 on CL right now for $400! http://forums.corral.net/forums/5-0-5-8-engine-tech/1253086-eaton-m112-install-5-0-ltd-pics.html
This Is fantastic that you brought this up here and now. I have been looking and researching and watching all these guys on the mustang forums running ridiculously cheap setups and still maintaining complete driveability on the street and track with the right setup. IMO a single 62MM turbo to start with a stock block will be just fine. Of course everything in between needs to be made. I'd use cheaper parts for the beginning to see how everything works. As long as you read your gauges correctly, and prevent detonation, and keeping the boost to a manageable level, a stock 302 should take a decent beating. everything else just depends on what you're able to do yourself. the only other things you would need if not already had have been mentioned. A good fuel pump and regulator enough to run the boost pressures you want. A good ignition is always a must, and general common sense. Don't go trying to push a ton of boost into the block and you should be fine up to 10-12 pounds. Also check out Hanger18. They give you perfect instructions on how to setup a Holley 4150 Series 750 double pumper. here>http://www.hangar18fabrication.com/blowthru.html. It's a good read for sure, and with patience, it's a helluva lot cheaper than buying a brand new blow through setup. Alot of the hardware and hoses and clamps and collectors and turbo parts can be had on ebay for cheap. To some it's you get what you pay for, but if you do enough research and look at some of the good and bad things that have happened to other turbo engines, you'll be able to tell decent quality parts from crap parts at low prices.
