CarIM000 build

[carim000]

im alomst at the end of my build i wish i made this topic before, il upload pics soon. my build is very stock:- nissan engine gaskets.-oem barrings-oem piston rings-oem internals-new water pump-took out the butterfly system-oem clutch-bigger intercooler

*already have:-3 inch exhust custom-3 inch down pipe custom-turbo manifold custom-tdo4 hla 19t turbo

took the head to a machine shop and i just got it working right and changed the valve (i dont know what its called in english exactly,but they are put on the valves they come with the gaskets).as i was pulling the head off the block the plastic part of the detonation sensor broke

Q's:1) the car was running for a while with out the detonation sensor, does it really change anything?cause i didnt feel any diff when i had it pluged before => is it really that imp to get one?

2)when i took out my spark plugs they had some white on them ,so i was wondering wat to do?i talked to HD to get a stage 2 chipe ,but one of the mods is a t28 from an s14 ,i mailed HD and they told me that the turbos are close but they arent sure !dose any one have some feedback from HD?!dose any one have a better solution for other than HD stage 2 chip?!

thanks alot guy for help earlier !

That turbo is good for like 315-320hp, so it's basically a stage 3 turbo. You will need 550-750cc injectors, Supra/GTR/Walbro fuel pump, Nismo/Sard Fuel Pressure regulator.

[carim000]

im gona get a walboro soon but for now i at 1 bar i dont know if i need bigger injectors

is a t28 from an s14 close to the tdo4 19t that i have?

dose anyone have any answers to my 2 questions

detanation=nock sensor? you dont have to have on, but it isnt good to run w/o it.

similar......

yes you most def need new injectors for 1bar

Above are the 2 compressor maps.

Here is the math to compare them since one uses pounds and one centimeters.1lb/min = 14.472 cfm

TD04HL-19T TD04L Comp Wheel: 46.0mm/58mm inducer/exducer, Trim 63 Turbine wheel: 52mm diameter, 79 trim, .49 A/R

GT2560R Comp Wheel: 46.5mm/60mm inducer/exducer, Trim 60 Turbine wheel: 53mm diameter, 62 trim, .64 A/R

Here's a map comparing the .64 A/R Disco Potato (GT2860RS, larger than the S14 turbo) against your turbo on some sort of fiat coupe.



(found here http://www.fccuk.org/forum/ubb...26687

So, all things considered and considering the info in that link above, your turbo seems somewhat equivalent to the .64 A/R GT2860RS (which is good for 315-320hp on the CA), bigger than the S14 unit which is good for 275hp on the CA. Anyone else wanna chime in?

i read that fiat topic a long time ago,and i knew that the turbo i have a good one ,but isnt the GT28rs a ball bearing ?!i thought that a ball bearing t28 would be would be better then wat i have! i know that the turbo i have is not a ball bearing but i read that the HLA(TDO4 HLA 19T) means the it spool really well.i opened up a topic like a year a ago about puting that turbo on my car

zer...using

after it was finished the car ran well ,at 0.6 bar but the spark pluges are white ,so this got me worryied.

so in conclusion the stage 2 chip from horsham development wont help me ?!

Your turbo will produce more power than an S14 turbo but will be laggier.

Stage 2 uses stock injectors and 15 lbs boost with S14 Turbo.

Stage 3 uses 444cc injectors at 17lbs boost with GTIR turbo or equivalent (GT28RS is a ball bearing equivalent of a GTIR+S14 hybrid; both good for 300-320hp on a CA18 from 17-21ish psi).

The turbo you have flows more than an S14 unit and is making you run lean (white plugs) with stock injectors and ECU.

In conclusion, go for stage 2 if you are:- trying to be cheap and not upgrade injectors,- you wont be going higher than 15 lbs, - are content not realizing the turbo's full potential, - are content spending $250 now and another $250 later when you do decide to do it right

If you wanna do it right and be safe, buy a Stage 3 and some Mitsubishi 450cc injectors ($50 on ebay).

I don't know how else to say it, you need more fuel to run that turbo at 15+lbs and buying a tuned chip that keeps stock injectors and maxes them out doesnt help you.

Good luck, let us know what you decide.

first of all ,thanks alot mbmbmb23 for the info ,i really appreciate it .didnt reply earlier cuz i had been busy ,i welded my diff ,cant wait to c how it change,anyways .i think the best way to go for me to stay on the same boost (0.6 bar ) and get :1-fuel pump2-wide band3-nistune 4-injector 444cc or bigger *after havin all these parts ,i will raise boost level.

i think that would be the best way ,dose any one have a better solution?

*as for driving it now without those part ,i already have a FPR would that help me now @ 0.6 bar ? mbmbmb23 dont forget i still dont have a z32 AFM(which is recomended for the stage 3) ,that i should also get soon

I went with the setup you have above (Nistune, Innovative WB, Walbro, Z32maf), except I'm using Deatschwerks 750cc's. Make sure you get a wideband that's compatible with Nistune. Also get a Nismo or Sard fuel pressure regulator.

[ca18detgabby]

if you are going to go all out like that, pick up an N60 or N62 maf and some real big boy injectors and you should be good for some real power(w/ proper tune)

you will be maxing those 444s out so quick it is silly and just be wanting more. might as well get some 555s(at the very least) or 750s and be done w/ it..

Your best pick up would be some EVO 9 560cc take offs.

http://cgi.ebay.com/ebaymotors...ories

http://cgi.ebay.com/ebaymotors...ories

etc. etc...

If for some reason you do buy smaller, get DSM 450cc's on ebay for $50, not Skyline/Pulsar 444cc's for $100+.

[carim000]

ok so for fueling :

1-a walboro 255 2-EVO 9 560cc *would it be enough for 1 to 1.4 bar(max) on my turbo?

as for the maf , a silly question ,people change their maf's because the original cant read that mush air right ,not because it has a biger diameter ,or do they both help each other ?

the n62 is the 300zx maf ,which is almost impossable to find here in my country because Nissan didnt bring that car to the market here!but the n60 which is maxiama right ?!it would be easy to find here .and btw i have a KA24de maf that im not using .would it be of any help to me?

i have a FPR ,but its not sard nor nismo its one of those universal ones, wouldnt that work for me ?

mbmbmb23 wat turbo r u running on ur ca?

thanks alot guys

[ca18detgabby]

tim had issues w/ those evo injectors as their flow was all over the chart. make sure you have them clean and flow tested.

rx7 injectors are right around the samem spec as well.

they use larger mafs because they are capible of metering more air flow do to their larger size sensors.

n60=maxima(as well as na z32)

n62= tt z32

ka=wont do you much good.

p60= almost as good as a n62 from a q45

universal should work w/ the nissan adapter IIRC

Evo injectors do have a variance. I bought a used set off ebay and had them flow tested and cleaned at Deatschwerks....one was 560, anothr was 564...so.....I ended up letting them keep them as $300 credit toward a set of their 750's for like $375 or something.

RX7 550's (as far as I know) are high impedence, you need low impedance.

All Z32's had N62's. Early J30's had them as well.

P60 has less resolution than the N62 and is therefore slightly less desireable when trying to mess with a tune in Nistune for example.

[carim000]

so is the n60 good for my application?

do you guys not recomend me buying those 560cc from an evo?

would i need more than 560cc for my application?

would a universal FPR help me now just to drive at 0.6?or should it be a sard or nismo?

most importantly ,with proper tune ,would my stock CA be able to 1.4 or 1.2 bar??!

how mush dose the stock head gasket ,and stock head bolts hold up?

too mush questions ,i seem to be a TRUE BEGINNER thanks alot guy for the help

rx7 are def low imped. think a few people ar running them. IIRC they have 2 pairs, 550s and xxxs? dont remember what the second is(480s maybe), but need to make sure all 4 are the samee that you run. Someone ran into this issue before.

I was suggesting the P60 if locating a n62 was difficult. not saying it was better by any means.

stock head gasket is good for over 400whp..... its actually real good assuming everything else is fresh....

assuming everything else is fresh and done properly, you should be ok to run more than a bar.

RX7 purple top 550cc are low imp, red top 550cc's are high imp.

This is correct.
