s14 sr head build

[jlmillionaire]

HI all,
I need some pointers or direction in which setup to go with. I really want to go all tomei, I need help in deciding to go with 260 or 270 procams. lash type i also want to go with type a springs because of quality compared to because I've heard bad things about bc so... since i have to do springs i figured to do the retainers as well, tomei is really expensive is anything comparable to them that's cheap because i'm on a low budget he he due to bills and sti car payment. The motor is still in the car will i be able to remove and install all these parts with the head still attached.i also want this to be a daily driver with good power and reliability and setup for occasional drifting when i get to as you can tell i am kinda of noob so please help me out in my project. thanks guys and one more thing i have stock ecu with no tune will i be fine for a couple months till i get money to buy stand alone? prob apex power fc since i'm poor haha aight thanks guys:snoop:

VE head FTW! thats what im currently in the process of doing :)

dude if you're building a sr head and getting alot of machine work done, it may cost the same as doing a VE head in the end...my sr head for sale cost about 4500 to get done and my VE head from Mazworx with there kit and all will cost about the same...and in the end, its stronger and it doesnt really need any machine work to make big power and by big, im planning to be mid 600whp...just my .02

[jlmillionaire]

Thanks for the input, at the stage that im at now i just want to do mild head work, things i can do on my own. neo vvl will be down the road for sure just not rite now. Besides i dont have the funds like that anyways.

[Imarvin240]

oh alright, well then i would say do tomei 270 cams (i had them in my sr head and they were awesome!) a lot of other companies make springs and retainers that are good (HKS and Supertech are great) i ran BC and honestly, i never had a problem with them in any of my 3 sr motors. Also, adjustable cam gears are a great investment!

First question...what turbo are you planning on running? There is absolutely no fucking point of doing all this shit on a head if you're gonna run a damn stock T28 turbo. Hell, I wouldnt even run aftermarket cams with it.

Also, do alot of research and learn what you're getting yourself into. Parts are one thing but look into how much itll cost for machine work and labor.

[jlmillionaire]

The turbo i have is a gt28r

dude there isnt a big problem with doing head work even if he is running a gt28...better air flow means more power and less stress on the turbo since you wont have to push it as hard. Also, it makes the motor stronger...i go over kill on building my motors because...i want them to last. i say build it, its not like you cant upgrade the turbo later on down the road.

[jlmillionaire]

Yes i plan on upgrading the turbo to top mount in the future, the gt28r is brand new and can handle more than 300whp i believe,I just purchased the tomei 270 from jgycustoms they always hook me up with good prices.I was thinking of doing the tomei type a springs and bc retainers or should i just get the 65 bc springs???

[teh smithers]

Why not try contacting the companies themselves? They'll know better than anyone else, I'd think. I mean, it's their stuff.

[Imarvin240]

the only BC stuff i wouldnt get, is cams. i have used both tomei and bc springs and they both worked great

[jr_ss]

Might as well keep it all the same company. BTW 270's arent going to net you any significant gains with that small turbo. There is a post floating around here or on NICO that has recommended cams for the mods/power level you'll be pushing.

[jlmillionaire]

I'm probably going with the tomei springs and bc retainers,I know my turbo is small but when i started this project i was new to it all, the gt28r is what i got stuck with for now i plan on doing a top mount in the future!! the sad thing is i never really got to drive the car stock so i wont even be able to see a difference anyways.But i can compare it to my sti so we will see... do i need to get a tune rite away after i install these parts??

[jr_ss]

Yep, tune is necessary after any change in engine performance parts, you shouldn't have to ask that question

[Imarvin240]

he said he was new to this stuff, cut the man a break. but yes, i would get a tune.

[jlmillionaire]

Im saying will it be safe to drive around without a tune? I want to get a apex stand alone in the future and learn how to tune my self.

[Imarvin240]

without the proper tune, i wouldnt risk it. its to much to risk on something so simple, you know? you could always just get a chipped ecu to hold you over till you are ready for the apexi. plus, if you are running a z32 maf, different injectors, larger turbo than the stock ecu is set for...all of those things without a tune, will cause the car to run like dog $h!t. let alone any other type of changes. to be safe and have the car run properly, i would say just go and get a nice safe tune on it till you are ready for the apexi.

Its one thing to make the head better since SR's head design absolutely fucking suck. Hell, just rebuilding it with fresh parts is enough for the most part if you dont plan on bumping up the redline. What's the point of building a 9k rpm head if you dont plan on bumping the redline from stock? Its a waste of money in my opinion.

But to run a damn 270 procams on a GT28 series turbo is overkill. It will hurt the engine's efficiency more than anything. Everybody gets caught up on the whole bigger number, the better mentality. Who needs 270 procams? Drag racers. 270-280 has no place in an engine that you want low/mid-end efficiency in.

On top of that, 270 procams...they're not really designed for HLAs. He'll need to go solid lifters, they're not exactly drop ins for a reason.

I'm not spewing this out of my ass...I'm personally running Tomei 270 procams, but I'm also running a damn GT3582R turbo. Fully built Tomei everything goodies for the head, valve springs, valves, retainers and solid pivots.

dude he said hes going to a larger turbo soon (the gt28 was what he has to start with for alil bit...read the whole thread first). second, look at the head im selling, i also have 270 procams with solid lifters and a $h!t ton of head work, i know what it takes to build an sr considering this is my 3rd sleeved sr (let alone all the other motors i've had).

the man is building in preperation for the setup he is getting, not what he has right now (it would be stupid to go with one head setup now and then switch it when he gets a different turbo setup, makes no sence and is a waste of time and money) also, i have never had any efficiency problems with 270 cams. i originally ran a 2871 and then switched to the gtx35 with a tial turbine housing and am now doing a vvl head.

in the end, if he does plan on going to a larger setup, then build for the larger setup (no reason to build half way and then have to go back and finish it)

[jlmillionaire]

So what should i do? Go with the 260 to be on the safe side for daily driving and mid to low end tourqe,I just want to do things rite the first time so i don't have to change them in the future.I also have greddy adj cam gears that i was going to tune for low end power with the 270 and the 270s i put money down on are lash type so there for i wouldn't need solid lifters.

[jlmillionaire]

Ima put a wrap on this, i'm going with 260 procams lash type with bc springs and retainers.thanks for everybodys input and maybe you guys can help me out in the future as well.

[jr_ss]

he said he was new to this stuff, cut the man a break. but yes, i would get a tune.

He said he was new to Nissan, not cars... He drives an STi, I'm sure he's been around long enough to understand the changes performance parts make and how necessary it is to tune for those changes.

The 260's will suit that turbo much better than the 270's. Just keep in mind you will not be able to rev the motor to the sky. You'll probably end up in the 7.5krpm range which will be fine, just don't bounce off the rev limiter too much or you'll be throwing rocker arms and spending more money to fix bent valves. Good luck and remember, if you change any aspect of your motor you should atleast have the AFR's checked to make sure you're not lean anywhere.

[jlmillionaire]

as far as the afr,i was thinking about getting the innovative wide band or aem ,im not really that new i have knowledge i just like to ask questions before i waste my money lol ...

[jlmillionaire]

i might even invest in a bee-r rev limiter for peace of mind.. lmk what yall think

[jlmillionaire]

well if i was to go solid to build 9k rev range ,the head would have to be taken of the block and i would have to re shim everything,and obviously remove hla. i think that would be to much at my skill level right now.and not for nothing how do i pressurize the cylinders with a compressor correct.
