2000 Ranger 2.5L motor build help!!!

[dagraytis1]

Ok heres my problem i have a 2000 ford ranger with a 2.5L engine in it and a 5-speed trany now i just want to get the motor ready for a turbo so like pistons and rods etc..... Now the Problems are will 2.3L pisons and rods work for the 2.5L because i see very limited supplys out there for my engine...... if any one can give some guidance to wat i should buy please be specific with everything to looking for at least 220HP with no turbo if possible and to move to turbo in the future thanks in advance

[fordnut71]

yes the 2.3 rods an pistons fit the 2.5 block.
dont think theres a way you will get 220hp out of a 2.3 n/a. not unless you plan on running 13-1 compression an very high lift cam.150 hp would be more realistic.

[Jesshwarren]

You can use the 2.3L pistons and rods but you will need to swap in the 95-97 2.3L crank.

2.5l pistons std. bore 8-1 comp for use with stock 5.2 turbo rods or a 5.2 crower rod. http://racerwalsh.zoovy.com/product/RWA1552_0/RWA1552_0__pistons_std_81_52_25.html

Okay i see now if i want like 165HP N/A what do i need??? 1- is the crank from the 2.3... does that fit the 2.5l fine also 2-pistons and rods.... if i buy the ones highlighted do they fit fine in the 2.5l block with the 95-97 crank and where can i get the crank at??? also what else can i do to get more power with out putting turbo yet

[xr4man]

if you are builbing your engine for a turbo application, you won't be able to make the kind of power n/a that you want with the low compression pistons you need for a turbo motor.

turbo motors without a turbo are lucky if they can get out of their own way.

i think you either need to build for n/a power OR turbo power.

Yes a 95-97 2.3l crank will fit into your 2.5l block. You can pick up a crank kit at most auto part stores for 150-200$ http://www.rockauto.com/catalog/x,carcode,1138081,parttype,5292

[dagraytis1]

ok so if im better off just building a turbo engine because i want turbo so the best rods and pistons to use are the 2.5l pistons std. bore 8-1 comp for use with stock 5.2 turbo rods or a 5.2 crower rod right and wat about the tranny do i have to do anything to handle the extra power??? other then clutch and presure plate srry if im bothering a lot this is my first project got a lot to learn

[Soul]

You'd probably be better off snagging a turbocoupe or some other factory 2.3 turbo short block to start off with. All the internals are forged, the pistons dished, and even a block drain hole. People make 300 hp on stock block.

[fordnut71]

you can sech car-part.com for a lot of the stuff you looking for.
you can keep your 2.5 block you just have to drill an tap it for the return. its easy to do.
95-97 2.3l crank
85-89 2.3 turbo rods an pistons
get a turbo coupe manafold with the ihi turbo an your boosted till you fell the need to upgrade.

[dagraytis1]

ok well i have the 2.5l block so i have to work with that wat do u mean by drill an tap for the return??? srry new to this

[Soul]

The oil from the turbo needs to be returned to the block. On a turbo block there is a 3/4 (I think) threaded return. You can either tap the block, or you can put a return in the oil pan. I heard that some people have problems with oil backing up into the tube with that last setup though.

[dagraytis1]

so if i dont have a turbo block then i have to tap my 2.5L block and run a line to the turbo from the the block right???

[Soul]

or your oil pan either or, go to turboford.net and search there a ton of examples of people doing it on the cheap. Usually with gas stove stuff lol. But ya there needs to be a return for the oil from the turbo.

[dagraytis1]

I Also wanted to know if this turbo (turbonetics GT-K turbo) Will Fit with the turbo maniford being sold on this site the web site for the turbo is http://www.turbo-kits.com/gt-k_turbochargers.html

[Soul]

You just need to make sure that they are the same flange. For example ford uses a t3 footprint on the factory turbo. So if you put a new turbo on, you need to make sure it has a t3 foot print. Also make sure if the turbo you want is externally wastegate that the mainfold you select has a provision for it.

[fordnut71]

you will be drilling the side of the block an using a pipe tap to put threads in the block for fittings. so a search on here an you will see how its done an where to put it in.

[dagraytis1]

i see thanks a lot well im going to start buying some stuff in like 6 mths ill put some pics up of what i did so far thanks alot again i learned so much also can someone explain a little how a wastegate works because the turbo im getting i do not see any info on the wastegate

[AJ_Fritz]

a wastegate just divert energy around the turbine to regulate boost and keep the turbo from overspeeding.

[dagraytis1]

thanks helps a lot one more thing can you keep AC even if the car is turbo charge???

[nagelandy55]

Yes, you just have to run the right header. I believe the header Jess sells will allow you to keep AC

[dagraytis1]

does any one know where to get a downpipe for thr 2.5l ranger???

[Soul]

^his welds look purdy
Also 40bob.com does some or ebay the parts.

[nagelandy55]

all depends what turbo you put on, if its a T3 you can use a stock downpipe.

[dagraytis1]

ok i have a change of plans!!!! I was doing a lot of reaseachand i dont want a turbo ranger i want a N/A Truck I need to see if anyone knows whats pistons and rods to use and where to get them? and what else can i do to get the most Horse Power and Torque out of the 2.5L with Out using Turbo i know it wont be over 200 HP Right?? thanks in Advance

[fordnut71]

u can use the stock down pipe from the turbo coupe.

[muddpawz]

get a supercharger kit, injectors, cold air, exhaust and a chip, and let er rip!!

Kiss torque good by. You will want10-1 comp a lot of head work a cam a very well balanced bottom end that can support 7K RPM's. With no turbo you need a good flowing head and high RPM's to make a big HP gain.

[muddpawz]

you'd be better off dropin a 302 in it for the cost and headache!! good luck!!

[fordnut71]

think you just need a mini stock motor an youll have what you are looking for.

[dagraytis1]

so without turbo im not getting any power right well thanks its going to take a long time because of money but i will keep you updated

[66muskrat]

possible thought.. spray the hell outta it. food for thought, TC piston with the 5.7 crower rods?
