this is just a list of the stuff i think i need and the prices if anyone has any diffrent ideas and/or something i missed please tell me thanks

 

the block out of a 78 280z (f54 i think bored .030 over )no cule on price calll shop monday

 

n42 head (have)

 

will my intake work (the one off the 78 n/a 280z)????????????

 

turbo manifold ( found nice one for 80$)

 

turbo ( ????????)

 

ecu 125$ are sds 900$

 

ka pistons need 6 but the ka a 4cyl maybe dished to lower c/r

 

240z rods (seem to be the hardest thing to find )

 

maxima crank( hope to get lucky and find one in the junk yard are 200$)

 

turbo mafs (junk yard maybe)

 

and 5 speed trans ( 125$)

 

i have the r200 in now i think

 

i would like to have around 250 rwhp and be able to drive it around all day

and maybe turn the boost up alittle when wanting to race

 

please tell me if i left anything out and thanks for all the help

If all you want is 250 hp, why go to the trouble of building a stroker motor? You can turbo the stock N42/N47 engine (F54 is in '81 and later ZXs only) and get 250 hp EASY, with a stock turbo, an intercooler and the stock ECU and fuel system from a ZX turbo.

I dont believe I've heard of 300 HP crank (around 250 RWHP) without 13:1 compression or so, which would not be running on pump gas without massively retarded timing.

 

I have heard of 287 crank HP with big bore SUs, and it runs on pump gas, its a guy who works for Rebello and owns several track records, despite this fact nobody believes it exists, his name is Mike Yoes. You can find his Thunderhill 1:57 record here:

Expect to pay a ton of money to do the stroker buildup, and then very ported heads. As for MPG I have no idea, but traditionally big cammed cars dont make MPG, they make top end power. Thankfully these cars are light so low end should hopefully still be acceptable, especially if your going to gear it "appropriately." I was going to do a budget buildup with my F54 (re-ring it, new bearings/seals), and slap on a ported N42, but I decided to just go turbo.

 

You have mentioned parts, but I didn't see anything about a cam, your heads and cam go together to make power, simply adding more cubes, wont do much alone. If your making 168 HP on 168 cubes (for simplicity), and you add 18 cubes expect to make maybe 18 more HP. You are going to need to increase VE to make more HP, and of course RPM since this will require a bigger cam. I would suggest not looking at second rate shops for head work, not only for HP but for reliabilities sake, and hopefully some retention of bottom end power.

Ok, now I read the subject line :rolleyes:

 

Why go through all that trouble of stroking it, unless your looking for monsterous HP/TQ? Refresh the engine or just run a good condition junkyard block, freshen things up a bit (injectors maybe, better fuel pump, etc) and you should be able to make 250 RW fairly easily, I'm looking for simply about 250 crank to start with.

 

I would suggest hitting the Turbo forum for some surfing, for your power levels I am guessing a hybrid turbo is going to be the way to go, boring out your stocker or a core that you can find, and a good intercooler and some way to fix the fuel issues with such power (more pressure, upgraded injectors, some way to avoid leaning out i.e. rising rate regulator).

would this be 250 at the wheels

 

and how would one go about do that woudl i not have o lower the c/r so it doesnt bloom up

 

Yes, 250 whp. I do that with stock ECU and stock injectors. You will have to intercool the crap out of it, as your stock CR is 8.8:1, but you can get that with about 14-15 psi boost. The easy way to lower the compression ratio is to use a F54/P90 turbo motor. Otherwise, bolt on a P90 head, but you won't have the benefit of turbo pistons - no biggie if you keep it tuned right so you don't detonate.

 

I wouldn't try to get any more than 250whp out of a stock N/A motor, but I know people who have done it.

the reson for all the hassle doing a storker is becuse i know that i will what more hp later so why not make it eazier for me later soo when i can aford a big turbo and a huge intercooler a wild cam ( and a diffrent car for a daily driver)

 

Expect to pay a ton of money to do the stroker buildup why have to pay more than any other stroker buildup my machine shop will bore it for 72$ and the other parts i already know about (crankshaft rods pistons ) is ther anything iam missing

 

lets say i go with the p90 head can i throw that on a 3.1 with out head work

 

 

i know i need a cam but i would like to want till i have the car built to see what i need

 

 

and i would also dish the ka pistons to again lower the c/r

 

whats a cube ???????

:?:

 

i would like to have the c/r around 7.4/1 no real reson for that number other than thats what some moster boost motors have

 

and intercooler yeah what size would that be ( cheapish)

 

thanks for all this info plz keep it coming

You can throw any FI head on without head work. If you were going NA as I mistakenly thought, then you'd have no choice but to go with a big head/cam setup.

 

One of the great things about turbo is you do not need a monster cam, you do not need to kiss your low end, or your gas mileage goodbye. Now for raising the powerband to 6,000 or so, then sure I'd love to go with a cam too, but thats going to run you another few hundred duckets.

 

A cube meaning a cubic inch...

thank you

 

does anyone know of a good wright up of some one putting a stroked motor back togather are a book i should use

 

and does any one know where i can find the 240z rods they are the hardest thing to find so far and i have looked every where

 

 

thanks again

 

sorry about the spelling

ok first thing first. friend of mine has sets of 240z rods (one of them has full race prep so its good for about 600hp). he is member on this board and his screen name is jtaylor. now second thing why are you so stuck up on stroker motor (i dont mean that in bad way) when bone stock l-28 turbo motor can be taken to 400 rwhp (well i know 388 whp for sure) all it takes to get there is big turbo, good intercooler, injectors, fuel pump and you can still use stock electronics (very risky but it has been done). now you wonder how am i so sure well jtaylor has been runing this setup for two years now at 360 whp (388 was on race gas going very lean but you have to understand that was on STOCK ELECTRONICS). so the best thing would be to start off with 280zxt motor and go from there.

well Ivan.....

can you tell me what parts i should use on a L28ET non-stroked motor to get say 350rwhp+..

i plan on using a EMS also... also this needs to be on pump gas (93).. and i dont mind opening the motor up for internals.

 

thanks

to make it very simple go back to announcements (sp) forum and email the guy with that orange z that you have replied on (jtaylor) and since its his car and his setup he will be able to tell you more about it. he wont mind it i know because he is super nice guy who knows his z stuff.

ya i just spoke to him, super super nice guy, he even found me a Z near him that he is gonna look at for me whenever he has time..

very very nice guy, and has one hell of a car too.

he told me about his setup and his plans for it.

crazy power.

thanks for the help man.

Turbo would be the easiest way to get the Power you want. Rather then boring the engine down to nothing (will probably get wall flex), just set up and intercooled turbo system that has adjustable boost. (IMHO)

You can make 250RWHP on a bone stock L28ET with ease. The KA24 pistons will work but are not designed for turbo use and do not have the thick upper ring land. Stock turbo pistons are alot stronger and more forgiving. I would spend your stroker money on turbo, clutch and efi parts. When I trash a motor I have no problem throwing in another $200 junk yard motor. When a big $$$$ stroker motor goes it's gonna hurt.

yeah iam thinking the same thing about it being cheaoer to just throw in a turbo motor and be done so thats what i think i'll do

iam going to pick up my turbo motor today iam so :-D:-D:-D:-D
