Try contacting jimwolftechnologies.com for some great advice for achieving the power you want. Don't believe me, check out the '92 Sentra w/SR20DE spanking the 5.0 Mustang at streetfire.com (pg.7). Some of the parts were from JWT and they know thier stuff.

Yeah, i have one from my other sr. You think i should switch to a bigger cam. The car is setup just for drifting so i can't run to big.

And does anyone know of a company that does headwork. There is no one in my area that i trust.

For 400whp, a good cam would be some 264 duration 11.5mm lift. Ive got HKS 264 Step 1's and there very easy to drift with since there matched with the power of the turbo but cant wait to go bigger cams to take the powerband higher. If your gonna drift, you dont need 400whp anyways. 350whp is all you need.

LS1 would be the best engine for 450whp reliably but more costly than doing an SR to get the power. Stock LS1 into a 240 costs near 10k and thats getting 350whp 350tq. Still alot of work and money to get to 450whp or higher.

this is not an opinion thread or a flame or why I should do it its a how. Im buying a cheap ebay motor to build. My questions are what turbo would work good? gt35R? how many lbs could I push or should I. Im gonna run eagle H beams Wiseco pistons, good metal headgasket of course. what other things should I do to have it handle power? what cams are good? how big of valves can I go to? what fmic is best for a lot of power. can the stock 5 speed handle it. I really want to do a 6 speed but I heard they are not strong. what can I do to make it handle the power? what injectors should I go to? should I do a full stand alone? what intake manifold and header is best? should I do top mount turbo. 3 inch downpipe or bigger? what major things will i run into

OMG! :eek4: ....This not an attack at you, im not trying to flame you, and I dont mean to be a jerk of any kind but I finally realized why the moderators and older members get frustrated at how many times this or similar questions come up.

I would recommend doing some google searches on how to read turbo compressor maps and you will be able to tell how any turbo will work with your motor and how much PSI to run and if its realistic based on your motor setup.

FMIC usually have specs you can also look up to see what hp range they recommend and how much heat they can take.

5 spd will work the S15 6 speeds are crap and weak. That is unless you want to invest in the HKS transmission.

Turbos you can run bigger exhaust (3"-3.5") without worrying about back pressure lost like NAs.

There are many threads already on the pros and cons of a standalone ecu, depends on how often you want/need to tune and spend.

Cams affect the air intake of the motor, the different sizes will let more in and
at different rates. Also the bigger the cams the later you will really notice them 264 mid rpms, 275 higher rpms etc. So it depends on your turbo and your needs.

Also alot of people on here have worked hard and taken time to post thier setups and dynos or hp estimates, so why not look for some to get an idea and not reinvent the wheel.

Im one of the older members on the forum and i dont feel this is a thread to just tell a guy to search for the reason of, he actually seems like he wants to do it. He knows the rough idea of what he needs and hes just asking for some guidance. Thats why i already posted a list of what would be good for him to get. Read everyone elses posts before telling him to search because so far we were all trying to help.
 
#29 ·
I answered as much as I could off the top of my head and was more of trying to guide him to answers than flame him to search. I guess I was just being a little moody after reading several similar post, they all start to look the same. I will cut out the last line of my last post, it is excessive and TinyT I aplogize if I offended you in anyway. Good luck with your project.

no worries mosill im just trying to figure out what I need for my application...if this was a sb or bb chevy Id know what I need to do to make power but this is just my first time actually building a 4 cylinder and its funny because the more everyone educates me on these i find it hard to believe how much power can be made cheaply and easily. so everyone thanks for giving me some light. I pick my 92' hatch up in 2 weeks and then im just gonna buy a bare block and go for it! I have some awesome motor builders around so the block is headed for the machine shop. im going with the gt35r, eagle h beams wiseco pistons.....and so on.... the only thing im wondering about yet is fuel....the more I look into this motor the more it seems like i can make 500-550 hp just as easily so what do i need for fuel....full standalone...1000 cc injectors? custom rail? thats really the only thing up in the air.

heres a list i think might help
full race top mount turbo kit with their intecooler or other ic they are the best kits around
gt35r
apr
bosch fuel pump or twin walbro pump or maybe single walbro
1000cc injectors
new fuel rail
greddy intake manifold
3in catback
apexi profec d-jetro or aem ems which ever you preffer
built block sleeved with pistons rods maybe balanced crankshaft
metal headgasket
arphead & main studs
cryo treat a 5 speed sr tranny or get 300zx tranny
and for the head im not sure
correct me if i missed some stuff
also you would surely need to buy my bost controller in my sig

if you have a good sized budget I would reccomend a big bore kit with higher than stock compression. I have seen kits w/ pistons and sleeves labeled as 2.2L big bore kit that would give you a great amount of power across the board. It would make that 450hp mark alot easier to hit.

alright that makes sense, but now what do I go by for year because im buying a bare block, head etc...

Buy for whatever year/type ECU your engine was running, along with which sensors...for example, it would probably be easiest to use an S13 redtop setup, as long as you're using the same sensors & wiring harness for an S13 redtop. Obviously it's different than the newer VTC equipped motors (S14, S15) but if you're buying an Ebay motor to build, chances are you'll be using an S13, which is a lot easier to score parts for anyways...

There's a lot of posts here that say go with this certain brand or combo, but you really got to get into what it is you're trying to do. Is this for road racing (SRs have numerous issues that must be addressed to be reliable for it), drag racing (stock trannys won't hold up!), drifting (don't need a lot of HP to drift well), or what? This will be the foundation of what your combo needs to be built to, to be efficient.

I built mine to be more drag & road race oriented, as I'm not into drifting. A D-Jetro is not required for ~450HP, a regular Power FC is fine. Whoever thinks the GT35R is "very laggy" obviously never drove one daily like I do...Injectors need to be at least 850cc at ~450HP level to have enough duty cycle at reasonable levels...Yes 600s can make that much, but you have to run them at much higher duty cycles/pressures which causes tham to fail prematurely-something you don't want happening under boost-KABOOM!!! A stroker motor may make more HP due to its extra size, but most stroker motors don't last as long as stock displacement motors. Sleeves aren't necessary unless you have to overbore more than 20 thousandths, although good sleeves are necessary for a HIGH HP application (over 600).

thanks matt k for the info. The car is mainly going to use its power for straight line. any handling/cornering/road racing/ drifting will just be for fun, so im not going to build it strictly for those reasons.

right now im going with a...

feshened up and sleeved block
proffesionally done head work
gt35r 3 in. inlet 4 in. out
4in. downpipe all the way back, no cat, to a magnaflow muffler
1000cc injectors
aem ems
custom fmic setup
tial 40mm wastegate
greddy intake manifold
300zx tranny

and etc. etc. etc.

what is a good top mount turbo manifold
and what is a good non ssq bov

I think some of the setup posted for his 450 goal is an over kill. I make 450+whp and 370+wtq through a full 3" crush bend exhaust with a muc smaller set up.

hks step 1 264's
mspi/tdf full race manifold
top speed intake manifold
garrett 57trim turbo
power fc
72lbs inj
cometic head gasket
apr bolt
with basic bolt ons
I made 402 and 335 on pump @19psi
I made 440whp and 366 on c16 23psi
Because of the restrictiveness of the crush bent exhaust I have been running off the down pipe and the car pull harder. I just have not gotten new number since.
