What to do for 12's?? (RB20DET)

[RB280SX]

Ok, I know that some of you guys might say something negative, but I'm asking just once, to contribute. I've searched and can't find anything, so I am asking here.

What is the cheapest route to hit high 12's with an RB20DET in an S13 with no carpet, backseats, and spare tire? I want to beat my friend's 300zx with tt swap that he has invested about 4g's into the swap alone. My max budget is currently 500$ (I've spent ~1500$ so far, trying to keep this car under 2g's). He says that it can't be done. Well, I want to prove him wrong .

So far, I have a filter (not sure of the brand or where it came from), 3" DP and testpipe, 3" catback exhaust, and a Johnny Racecar 24x12x3 Intercooler w/ Custom Piping. I'm going to be pushing around 11 lbs tuned with an SAFC II. Again, I am looking for the cheapest route (for bragging rights). Thanks.

[krayton]

nope, not reasonably.

unless u get hooked up here, hooked up there.

your looking for around the 300ish+ and some good driving. but getting to 300ish is gonna take more $$$

[RB280SX]

300+ to the rear wheels ? I thought that this would be achievable with 240ish whp. If I push the boost to 11 lb's and have the car strapped to a dyno and tuned with the SAFC, won't I get to the 240 whp mark?

I might just strap a T28 or T3 onto the motor and see what happens...

Btw, the stock turbo on these motors are only good for up to 12 lb's with an SAFC, exhaust, and FMIC right (from what I've been reading)?

injectors next with turbo upgrade

plus a hookeup ona wideband or some free tuning, cause otherwise thats $$$

240ish? better bring some slicks too. maybe a stage 5 weight reduction.

[DriftingisLame]

For 12's on a budget on a $500 budget, your gonna need to make some massive sacrifices.. First I would find a used turbo, probably a t3/t04e. Look hard enough and you can find one of these for around $300. Max out your injectors, and maf (both unsafe). Buy drag radials with the rest of your money (already exeeding $500), and then randomly pull a wideband out of your ***. Tune like a God with that SAFC.

Have everything hold for a few runs and you'll be in the 12's

Just like they say: Fast, reliable, cheap

Pick 2.

Oh and for the record, it is not safe at all to try this... thats too low of a budget.

[Joe]

theres no possible way your gonna hit 12's with 240whp.

and as for "cheapest way possible" im gonna tell you what i tell everyone else

Cheap, Reliable, Fast.

you can only have 2. never the 3rd.

Cheap and Fast, will never be reliable.

apparently the dsm world begs to differ .anyways you wont be able to reach your goal for 500$, no way unless you get some injectors free, know how to chip an ecu,steal a z32 maf, and have some one almost give away a t3/t4 turbo.i had ~4k total invested in my motor and it made 387whp no problem, and thats including the cost of new parts and some bargains i had stumbled across, but good luck trying to do that on 500$...

[RB280SX]

Time to start looking . Btw, Supra 440 from an Mk3 works correct? I'm about to purchase the injectors and a 300zx mafs for 250$. I'm also picking up a Walbro 255 fuel pump for 100$. I'm in about 350$, so now I have roughly 250$ to spend on a turbo (after I sell the T25 for 100$ or so)...

I am also not factoring in tuning cause I can get that done for very cheap.

I´ve said it before but as a fun fact a CA18 powered S13 here ran 12.28 with around 300 hp.He used stock injectors with higher fuel pressure and you can´t reach much higher on those.

I would say 300 engine hp to reach 12.99 or lower if you are a good driver and good traction.

With my setup, I'm going to be aiming for 300whp . It's going to be tough, so I'm raising my budget another 100$ ( , like that's going to do much...). Well, after I spend about 350$ for the injectors, mafs, and fuelpump, I'll have 250$ for a turbo, which should net me a T3 or T28 of some sort.

Yeah, 300whp and a pair of 10.5" ET Streets will take you there.I really don´t like the T28´s but that´s a bolt on and it´s easy.

..

I have a new Walboro that was used for 400miles... I'll give it to you for $80 shipped if that helps.

[RB280SX]

I'm running 8.5 in the rear. Hopefully I'll nail a 2.0-2.1 60'. I'm going to be purchasing all of the items later today or sometime tomorrow, and will have them installed and tuned by next weekend.

Emailed.

I mean 10.5" MT Street tires, the 12 sec guy used 7" rims to those tires. I don´t think you will make it with low profile tires.

/Mike

[RB280SX]

Ooo . I dunno. I'm pretty inspired right now cause one of my friends ran a 14.6 in a bone stock rsx type-s. The other ran a 14.0 with i/h/e and a vafc tune. As for my other friend with an evo..., he ran a 12.2 with a boost leak, basically stock with an increase of boost, exhaust, and a vishnu tune.

jimmy!

whats that gif from ^

and good luck with that 12sec pass! let us know how it goes

[Arrow]

I know that show! FIREFLY! one of the best sci-fi tv series out there, too bad fox cancelled it after the first season.. =(

As far as the topic is concerned, I had been doing some figuring and in order to run a 12 sec you would probably need to have better than a 1 hp per 10 lbs of car ratio... so either a decent bit of weight reduction (to get the weight close to 2500) or closer to 300 hp... which is doubtfully not going to last too long on your budget (inless as others have said, you get some good deals/steals and hookups)

Good luck though

[krayton]

i know, im a nerd! i love that show.

but i just couldnt remember what episode

[SeVa-S13]

Nitrous.

It's from the Train Robbery episode. Technically the 2nd episode, but it was aired before the pilot for some really dumb reason... Stupid Fox.

[jdmser]

drag math says you need to weigh 2800lbs and make 260hp for a perfect 12.8- wet kit should get the job done

[lyon23]

like everyone has been saying on a udget your really pushing it..I got 325 on my rb20 right nowon my s14 with rx7 460cc injectors, t3/t4e turbo, same FMIC, safc2 and welded diff.. on regular street tires and a full interior I got 13.0 at gainesville that's with a 2.2 60'. The turbo has got some lag on it but great top end. I was looking for a ultimate emanage to tune instead but for now I'm not even driving it. If you want your engine to last I'd say don't build it the cheapest you can and then dog it out. Another thing who says you have to tell your friend if you spend more money. he doesn't have to know you paid full price for things.

[RB280SX]

Well, time to start proving people wrong . I'm not going to use nitrous because I find it risky using it with stock internals.

o_O

my idea of risky was trying to run that gay safc with 300hp (which i couldnt/didnt wanna fine tune too)

sorry if im offending anyone with an safc, but those are a lil scary. just the idea of tricking my ecu finally got to me.

i took a huge hit in the wallet and went with the aem, but no regrets. fine tuning the aem to what the safc was trying to run we made near 50hp

[RB280SX]

Yah, but an ems is going to cost about double my budget (1000$)...

[RBTALLY]

Nitrous.

+1

It is safer than some of the other options... my new setup has a 50 shot to help build boost at the line

[RB280SX]

Well, I found a T3 Turbo with .42 AR. I was wondering if this would be good for 300whp.

Always hard to tell when we only have A/R but with the right compressor, yes.

if you cannot afford to build your car right......then maybe you should wait and save up a bit. It will probably be cheaper to build your car right, than to replace your motor after building it wrong. thats why my rb is still stock:)
