Question about turbo needs

[krackajak]

K guys, found your forum the other night, its great. Im a 17 year old kid who just bought his first truck last night. I can already tell im gonna want to go the turbo route. I (like most kids) don't have money to burn. My truck is a 2000 extended cab 5 speed manual 2.5l ranger with 152000 miles. I would like to turbo it for as little as possible (meaning not ripping out the engine. how much boost can i give before having to put rods, pistons, etc in. I could do a head gasket and studs pretty easy) . I have divided my choices to about 3 "stages" Please give me some input. thanks.

Stage one:
turbo 300
header 200
38 mm wastegate 80
maf sensor 90mm 80
x calibrator 300
good for 5-10 psi?

Stage two:
turbo 300
header 200
38 mm wastegate 80
maf sensor 90mm 80
head studs 100
clutch 300
x calibrator 300
intercooler 180
head gasket 54
good for 10-20?

Stage three
turbo 300
header 200
38 mm wastegate 80
maf sensor 90mm 80
head studs 100
x calibrator 300
clutch 300
intercooler 180
head gasket 54
rods
pistons
rings
arp rod cap bolts
good for 20+?

Thanks again

With stage 1 going to need Fuel pump $90
Injectors $200
Exhaust?
Intercooler $200

I'd also look at piston/rods for Stg2.

[fordnut71]

find a turbo coupe. an take out the pistons an rods, turbo an the manfold. buy a 255lph fuel pump. also take the exhust down pipe.
buy a fmic with piping an you will pretty much have most everything u need.

[D94R]

If you go the turbo coupe piston/rod route like suggested. You WILL HAVE to swap in the 2.3 crank since yours is originally 2.5

[AJ_Fritz]

the stock fuel pump will handle anything the stock 2.5 will throw at it.

if you just turboing the stock motor (not recommended) your main concerns will be staying under 10 pounds of boost. keeping up with the new fuel requirement with injectors and a new MAF meter. intercooling really isn't required at these lower boost levels. then this is the most important part get a good tune on it from the start. Jess should be able to get you moving in this part. 93 octane will be a requirement too and it will have to be used forever. main problem here is your going to be running the stock head and its tight for a 2.3. on a 2.5 it might not even work.

anyone else having problems running a 2.5l at low boost with a completely stock combustion chamber. speak up now...

i know i wont even touch a Naturally Aspirated 2.3 head without removing a bunch of material from the combustion chamber and finish it with a polish. most times they are just way to tight.

[krackajak]

k thanks for the advice. Im trying to look at the larger picture. I want to go turbo and I don't have a ton of money. What is the bare minimum I can do to go this route?
Obviously I need the turbo, maf, header, wastegate. Could just his get me to 5 psi?

[krackajak]

well. Thats what i needed to know AJ, you we must have been posting at the same time. Looks like I should just build a motor.

[AJ_Fritz]

jess tried to run the stock head with the 2.3 and had nothing but problems with head gaskets. after the big valves and the chambers redone though i dont think hes had any problems head wise.

its just a complicated mess tring to do it with a stock motor. the head is the main consern. after that its pretty much dont get greedy, or you'll be picking up peices of pistons out of your oil pan.

as boost goes up octane must go up too. if you start with a lower static compression ratio then you can run more boost with less octane. but at some point you will be pushed out of pump gas. with a stock head that point is reached rather quickly. you can do this one of 2 ways run a dished piston, not an option because there isnt one, or remove material from the combustion chamber.

[nagelandy55]

I've using my stock head it has worked alright. I'm not sure if Jess took much out of the CC's. If he did that might be my detonation issue.

[Jesshwarren]

Right now I am running a 2.3L motor with stock T/C rods and pistons. It's like a 300$ short block. The way it felt today at the flashlight drags it feels like it has high 11's in it.

The built 2.5L I have setting waiting for next race season.

Just saying big $$ motor builds don't gain much over a 300$ build.

[PrerunningRanger]

Hey jess, justin just left a little bit ago to go get my motor that im getting for $100 buck.. its a 1986 mercury turbo cougar.. so pretty much a t/c thunderbird... its only got 60k miles on it... and i think its a very very good deal since its only $100 bucks... lol when ever justin comes down with it ill have some pics posted of it.. and ill be posting pics of my truck soon also but good job on your racing yesterday.. lol

[flyin]

all i did was remove the sharp edges to eliminate the hot spots

[Jesshwarren]

Yea that stock T/C SB will support a 11sec pass ;)

[krackajak]

Hey guys real quick. I know I'm new but I've been looking around and it seems like there are a lot of questions as to what parts to get. Would it be possible to take the parts list that Jess mad (i think it was Jess) and just list the specifics of what is used and to what degree. There may already be one but I havnt found it. For example:

Compressor:
Holset Hx35/40
Holset H1C
Garret (don't know)

Pistons:
Wiseco (details here, still dont know)

etc
etc
etc.

I'd really appreciate it.

[fordnut71]

heres a list of some of the turbos to find
92-93 2500-3500 intercooled Dodge Cummins has the large compressor H1C holset with the 18.5CM exhaust housing.

94-98.5 2500-3500 Dodge Cummins have the HX35.

98.5-02 5spd has the late model HX35 about the same but compressor has one less fin and will whistle louder.

98.5-02 2500-3500 auto has the 9cm HY35 holset.

[krackajak]

Thank you fordnut, but i'm talking about making a list for ALL of the parts. You listed the good turbos, but a compilation of everything would rock. Best turbos, maf's, tuners, headers, injectors, rods, pistons, etc.

[D94R]

There's a million combinations, and what works on one, won't necessarily work on another engine, even if both engines are identically setup. Quirks of working with the 2.3. You can usually get close though by following other's combinations, then tweaking with your own modifications.

[AJ_Fritz]

one of the main problems is even though your using the same identical parts as another guy everything in the air intake track is usually a little different. when you get to this level there is no off the shelf, exact same parts, to buy. everything is modified. minute changes effect the air meters and the air meters effect the tune.

[Soul]

Head over to turboford.net under the off topic bs section there is a proven power combo thread. Just to give you an idea or two.

[krackajak]

thanks soul, that exactly what i was lookin for.
