sr20 upgrades, what to do next?

[agile_moments]

After the basics that occured with the swap (downpipe, exhaust, bov, fmic, turbo timer, boost controller) what should come next? I've read some different things, but it seems like maybe the fuel system needs to be next? upgraded pump, injectors? Is this a correct assumption? What else should I be looking at next to begin making more power?

[Poor_S13_Driver]

I would highly suggest you get a new fuel pump before you even do anything else to you car. From what i understand thats a no-no not upgrading that first.

[SilviaSlydSydway]

yeah you definatly need to get a walbro. You can get them in the advertisers specials here for around $95.

[kamikazestorm420]

stock boost is fine on stock pump. IIRC WD confirmed that a while ago.

but anything over stock boost i say get a walbro

[agile_moments]

alright, consider that done, what next

[nwmrkt]

if your going to be running the stock t25, injectors and Maf is any kind of engine management needed to run it safely like SAFC? Even if you up the boost abit?

[agile_moments]

i plan to upgrade the maf and injectors, but don't know at what point I need to do that

[jr_ss]

How about a full 3" exhaust?

[ILikeMy240sx]

no point in upgrading injectors + maf unless you are going with a bigger turbo.

[luv2spedup]

you can consider doing the headgasket and head studs

[S13FASTBACKSR]

no point in upgrade hg and head studs if your not upgrading the turbo and boosting biiiig...i say upgrade the turbo, injectors, maf and get thet tune..or go cheaper and do a vlsd or a lsd of some sort..oooor you can buy my set of hks step 1 camshafts i have that require absolutely no other mods

Bigger turbo. But you cant go bigger turbo w/o getting everything else. When i say everything else i mean fuel system, headgaskets, cams, and all that other junk (every important things).

Think of it as one big step.

[goj_cloud]

you dont need a new headgasket if u run a bigger turbo, i know people runnin the gt2871r turbo stock block

[S13FASTBACKSR]

^^^ true..when i said there is no reason to upgrade the hg unless upgrading the turbo i did not mean you must upgrade the hg when you upgrade the turbo..sorry for confusion..upgrading the hg all depends on how much boost you want to run

[agile_moments]

exhaust and lsd is done. what gains can be expected from cams?

[S13FASTBACKSR]

imo cams are the cheapest upgrade you can do to earn the most amount of hp..when you upgrade your turbo you should get bigger injectors which requires a tune which in the long run costs quite a bit more money than cams..the cams i have are hks step 1's very nice condition they look brand new..they are absolutely plug and play no tuning or valvetrain modification needed..are you interested? do you have aim or email? let me know

[SlowS13Silvia]

whoa alex whats up man this is eric. where have you been i havent seen ya around, also how much do you want to sell your cams for i might be interested...

[DrifterProdigy85]

HG is all based on power output and intake temps. I run 19psi daily with my 2871R .86 on stock HG and block with no ill effects. Ive even ran 24psi on 100 octane with no problem. On stock turbo, no gains will be had from cams. Itll drive like crap because the cams are made for a different powerband than the T25 provides. Id go 550cc injectors, Z32 MAF, and a ECU tune for GT28R at least. Tune will work fine with the T25 and work better with a larger turbo.

[goj_cloud]

i ment that towards TchouikoS13 he said you have to get a new hg

what differentiates step 1 from subsequent steps? Will these change how high the engine revs?

As far as a bigger turbo, is there anywhere to find a good turbo for less than 1,000 dollars?

[S13FASTBACKSR]

I dont know what that means

these wont change how high the engine revs, if you are on the stock tune then you still have your rev limiter..but you will gain power after 6k rpms because with stock cams you start to lose power after 6k rpms. with these you will be able to go beyond that without losing power

[agile_moments]

I dont know what that means

meaning is there a step 2, 3, so on? if so, what is the difference between these

[S13FASTBACKSR]

there is a step 2 and 3 yes..hks makes a 256 duration camshaft in step 1 and 2 (however 2 is only for the intake side and only for a s14 and s15 sr). they make a 264 duration in step 1 and 2 as well. and i believe the 272 camshaft is in 2 and 3. what determines whether or not the camshaft is a step 1 or 2 is the lift of the camshaft. step 2's have a higher lift than the 1's and require aftermarket valvesprings. the camshafts i have are a step 1 264.

the higher the step the more other upgrades you have to do to support it.

example:step 1 cams - no support upgrades neededstep 2 cams - needs aftermarket valve springsstep 3 cams - should have just about everything replaced

my setup: (not installed yet)HKS stage 2 264in w/vtc HKS stage 2 272out peak performance valve springscryotreated OEM retainers

correct but what i am saying is hks makes the same duration cam in 2 different steps and what determines whether the cam be a step 1 or 2 is the lift of the cam. you have a hks 264 step 2 cam in. i have a hks 264 cam in but its a step 1 because the lift of my cam is not as aggressive as yours

[SilviaSlydSydway]

Something cheaper and easier would be an exhaust manifold, and 02 Housing.

[spider_slayer]

yea, i was gonna say something like lightened fly and/or driveshaft. but that works too.

if your on stock suspension then start dumping money there, your engine set up is fine for now after you install the walboro.

[agile_moments]

coilovers, camber plates, strut and sway bars are already on. I guess I'm going to go ahead and go for the front mount, exhaust manifold and turbo outlet, then start saving for the turbo and necessary components

[TchouikoS13]

Now i didn't mean you HAVE too. I just like keeping my engines nice and maintained. As in im not trying to peak the internals. As in im not looking up how much power things can hold before blowing up. know what i mean
