All you would need to do is replace the camshaft sprocket with an aftermarket adjustable one. There are marks on the sprocket that tells you + or - and TDC. This allows you to raise or lower the camshaft timing depending on what you're wanting to do.

I have honda stunner bike i changed bore piston with connecting rod still smoke come when high tourqe


There are a number of possible reasons to get smoke including:
Cylinder bore scored, causing rings to not seat.
Damaged rings during piston replacement
Valve guides leaking
Mixture wrong (is smoke blue, white or black?)

Inhance the power


use high octane gas and a high output coil, and straight through exhaust with no muffler, add a high performance cam, bore out the cylinders as big as possible, get the heads ported and polished, use dome pistons, etc etc.

My 1197 tacoma 4 cylinder automatic w transmission has little power. I have tuned it up with some increase in power but not much, I average 23 mpg. what can I do to increase power?


You could put in a turbo or increase air flow.
You could buy an aftermarket ecu which is tuned for performance.
You could also get a machinist to make the cylinder bores bigger and put in bigger pistons etc but this may be expensive.
Or replace the engine.

Just wondering how much horsepower and torque a 383 stroker engine with a 4.030 bore, 3.75 stroke with a 278 crane cam with 222 degree at .050 inlift .470 lift, port and polished gm heads with 2.02 intake/...


I would guess you would be very close to the 1 horsepower per cubic inch ball park with very comparative torque figures, but...so much depends on how well the fuel mixture and ignition timing is set up. The port and polish work is also very important, bigger isn't always better, it's the shape that matters. Smooth ports actually flow worse than ports with an even cast surface. It's the protrusions and transitions that matter the most, not the surface.
On the dyno, at the rear wheels, I say about 290 hp and 300 torque with good gas and the timing optimized. This may sound weak, but it is an impressive real world repeatable attainable goal in my opinion. Peak numbers at the crank would be far higher, but driveline loss is huge, and so subjective because of tires, trannys and gears.

What is engine blueprinting?what is needed to bring out more power to the engine? For example, could mere balancing of like let's a pulley add some power to the engine? Thanks.


Blueprinting is a very exhaustive and extensive process of rebuilding the engine. When the engine is designed, there are specifications for every dimension of every engine part. Since the parts are mass-produced, there is no way that they can be made exactly to spec, so there's a tolerance allowed on the parts (for example, the weight of a piston would be specified as X number of ounces, plus or minus 10%). Same for connecting rods, wrist pins, the inside diameter of each runner in the manifolds, weights and dimensions of valves, etc.

When an engine shop blueprints an engine, it means they build it to the exact specification for each part and clearance in the engine. They may order 50 pistons for a V6 engine, and will measure all of them for all size and weight dimensions, and won't stop until they get six that match exactly. They'll then do the same for the six rods, six wristpins, the valves, crankshaft, etc. They'll take the intake manifold and will usually bore it out (or extrude-hone it, which involves flowing a high-temperature, abrasive clay through it at high speed/pressure to polish and enlarge the volume for better airflow). Ditto that for the exhaust manifolds. They'll do a full hot-tank treatment on the block, metallax the block (alternate heating and cooling of the block to make the crystalline structure of the engine block metal more regular, and thus stronger), cross-hatch the cylinders for oil retention on the walls (better lubrication and less friction as the pistons move), order cams with an optimum grind for valve lift and duration (this determines the airflow characteristics of the engine, where it'll make peak power and torque, etc), they'll knife-edge, balance, micropolish, and shotpeen the crank for less turbulence in the oil pan and lighter rotating weight (so it doesn't drain as much power), and they'll assemble it all to exacting fit and torque specs.

The end result is that you can gain 20% or more output from the engine, or even more still if they do porting/polishing on the components, extrude-honing, etc. With that stuff and custom-spec cams, the output could go up 30-40% even. It's a big power gain, but it comes at a big cost (as I'm sure you can tell). It's only really worth it on a race engine. Anyone who says they can blueprint a motor for a grand or less is full of it. You'd honestly be looking at $2000 or more easily if you only rebuilt it to stock spec with stock parts. Using aftermarket, high-performance parts, custom cams, extrude-honing, porting and polishing, etc, can easily kick the price up to $5000 at the least, and depending on the components you buy, $10-20,000 is very easy to ring up. It's not for the faint of heart. But it may be all the difference in racing, especially in an SCCA class like Spec-Miata racing, where engines have to be unmodified (as in, using only OEM parts). There's no rule against blueprinting as long as the parts are all available at the dealership parts counter. It says you have to use stock parts, but it doesn't forbid you from using the best possible combination of stock parts possible.

Looking for 2.5 engine on 86 fiero vin r


I just checked Ebay, and there are two listed. You might try Craigs List.

(Tips from me:
Port the Vortec head. Open the Intake and Exhaust ports, by smoothing them out, and smoothing the casting sprue lines out.

Put the Intake gasket, and the Exhaust gasket on the head, (After marking the area with Prussian Blue)
Scribe the opening of the gasket, onto the head, then match the ports to the scribed lines.

You also should round the valve guides top surface. (Where the valve stem meets the guide) There is a square edge that needs to be rounded. This square edge interferes with the fuel/air mixture, as the sharp edge breaks the fuel/air mixture down into droplets.
You want to keep the fuel/air mixture atomized, Not droplets.

Also narrow the casting that comes up the side of the valve guide. (Squared off shape that follows up the guide, and makes the Vortec shape swirl shape in the Intake port) Narrow it to more of a small rounded edge.

Do not polish the Bottom of the intake ports. Leave them as a rough casting. Smooth, and polish the Sides, and Top of the Intake port. (Do not get Extreme! You'll go into the water jacket with your die grinder! Factory may have had a casting shift that day. Just smooth things up)

Makes a nice swirl pattern for the fuel/air mixture.
If you polish the floor, (Bottom), of the Intake port, you will create Two swirl patterns, and they will collide with each other, making droplets again. (They cancel each other out. You want one nice swirl pattern flowing through the Intake port)

I can bring my 1985 Fiero up to 155Mph, (On dragstrip set up for this, tires, and proper safety equipment used). I can also 'Keep my foot' out of the throttle, and get 45 miles to the gallon on the highway.

You can use flat top 350 Chevy pistons. The 2.5 Vin R Fiero engine has a 4 inch bore like a small block Chevy. The pistons can be put on the Fiero rods. Same wrist pin size. The piston drops down into the engine block, about .030 below deck height.

(Wrist pin to piston crown height, is .030 shorter with 350 Chevy piston, compared to stock Fiero piston. You can buy 4 - 350 Chevy pistons AND rings, compared to the price of just the rings, for a Fiero!)

(Thirty thousandths. Real close to 1/32nd of an inch. .03125 is 1/32nd of an inch)

Fiero's have dish head pistons, so the drop in deck height, and using a Flat Top 350 Chevy piston equals out. (Better flame travel with flat top piston. Better burn, more power. Uses more of the fuel/air mixture than a dish head design)
If you can't afford to have them balanced, use a beam scale, and balance them yourself.

I can bring my 1985 Fiero up to 155Mph, (On dragstrip set up for this, and proper safety equipment used). I can also 'Keep my foot' out of the throttle, and get => 45 miles to the gallon on the highway. (Throttle Body Fuel Injection. TBI)

Makes a V6 Fiero cringe!

Timing Belt Snapped on 95 Rodeo


that vehicle is listed as an interference motor which means it could have bent the vavles or even hurt the pistons. One way to check is pull the plugs and perform a leak down test if air leaks out the intake or ex you have bent valves. Also if you know someone with a good quality bore scope you can put it in the plug holes and look at the valves and the pistons. How much to fix is hard it depends on how many miles are on the truck and what shape it is in to see if it is worth it to do. If the vehicle has very high miles you may want to look at a junkyard motor with lower miles may be the best route but if you get one with over 60000 miles on it replace the t-belt before installing to be on the safe side

Need info to rebuild 351 windsor motor 1998


port polish only on heads, they crack plus valve job. on the block and cam, that motors all torque so go with low end output, fat cam, 30 over max on bore-they crack. safest way for big power is a stroke kit. call edelbrock tell them you wishes and what you have now, main thing is how much your gonna have to bore to clean up walls, and they give you some good options. unless you have alota money and dont require this motor to be dependable dont expect more than 320hp and 350 ft of torque. 302 will take you farther cheaper and lighter for your money. if your talking for a car and not a truck- go 302 and dont look back

Engine swaps


Either one would be great, depends on what prices you can find, if your replacing the internals, then it doesnt really matter which one you go with, especially if you are boring the cyllinders. Be careful not to bore more than is needed though, as you are planning high boost. You will also need to either sleeve the cyllinders or at the minimum weld in a girdle at the top. As for the 4 speed, no, you will need to swap tranny's, if you go with an OBD-0 motor to match up to your car, the matching tranny's weren't hydraulic, but your old one will only mate up to a D-series motor, and besides, it would never handle the power. Careful on your selection of compression ratio on the pistons also. You will need to make sure you stay with a low compression if your going turbo (ie. 8.5-9.0) If your not slapping a turbo on immediately, you will either sacrifice power for now, or if you go with higher compression pistons, then they will need to be replaced when you boost. Also, make sure you google around and find what kind of horsepower ratings your expecting, and see what size injectors your needing, and will of course need to replace your stock fuel pump. You by this point will be needing some sort of aftermarket engine management also.
