Looking for a good setup 250/300whp for daily and 400/500whp for track

[rid'n solo]

I'm looking for the best and most helpful info since I don't have access to the net all the time. I have a '93 240sx h/b with 142k miles before I had 2 put it down, because some a@$ hit it while it was parked. I don't wanna pull it back out until I have some boost. The motor's still in good shape but radiator is gone. I'm looking for a good setup with at least 300 to the wheels daily driving and when I crank up the boost I want at least 500 to the wheels or close to 500. The 500 isn't for the street, just for when I feel like taking it out to the track. I've seen and priced a couple parts when I have the chance, but I'm just looking to do it right the first time since me and a friend are going to be doing majority of the work ourselves.

p.s. If you dont have anything helpful or some kind of good advice please don't say anything at all, because that would be a waste of my time.

thank you all for your help

First of all don't come in here telling us not to waste YOUR PRECIOUS TIME. YOU ARE THE NEWBIE. You don't run this place. And if you took a few minute to search you'd find all the info you need. SO NOW YOUR WASTING OUR(Nico's) TIME to answer your stupid question.Everyoen is going to tell you to search as will I.However I'll give you this info.If you want 300 reliable you can do thta with a good kit. t3/t4 turbo. Try IAP our sponsor I run their kit. Anythign over 350rwhp your going to need to get your engine built.AMS is our newest sponsor and they do full race build as well. Just dynoed a KAT at 718rwhp threw an auto transmission.To have reliability you should go with either an enth ECU or be on the dyno and have someone tune you. Welcome to NICO, please use search before making a thread that has been covered countless times.

+1... youll probably be spending spending around 10 grand.

youll need a nice t3/t4 or even a straight T4, huge injectors, fuel rail, fuel pressure regulator, fuel pump, some sort of engine management (like florida240sx said, either enthalpy, or something like AEM EMS), pistons, rods, rebuilt head with valve jobs, cams... basically all new everything in the motor. Youll also need a clutch, a good rear differential, guages, exhaust, and lots of time. Have fun.

[lilskyline240]

I love when ppl come on a board and think that by tellin us they dont have time to search well give them answers....it obviously took him time to write the post....time that could have been spent searching....

Id say go with the IAP stage 2 kit as it has everything you will need.....but if you have time to search around, youll find it prolly WAYYYY cheaper to pieced it together yourself

[Jookmasta]

whats ur budget for the project? this could help us throw out some more detailed suggestions on certain parts.

[KATwo40]

$10,000 ???? YEAH RIGHT!

GT35R, .82 A/R exhaust housing.

'nuff said.

Match that up with a good standalone ECU (AEM EMS, Haltech E8, etc.), 800cc/min injectors, a good pump (possibly dual Walbro255's), nice freely flowing fuel rail and adjustable FPR, 3" turbo-back exhaust and you have your 300whp daily, 500whp track setup.

http://www.agpturbo.com can hook you up with the GT35R for about $1200.

You can do this setup for about $6,000, figuring in the FMIC, misc. oil lines and fittings, good tubular manifold, IC piping, etc.

Thank you and goodnight.

I said what I said because there are some people who just have smart a@# comments to say and nothing thats helpful for those that are looking for help. If I offended anyone then I apologize, but to those who help thanks.

But anyway I'm looking to spend at least 5k but not more than 6k.

Thank you for the apology. Rest assured if someone decides to be an a$$, I'll take care of it myself .

I'm not going to tell you exactly what to buy for your goals, but I'll tell you this: if you want something capable of 500 horse with any kind of reliability, you're going to need to fully build your motor. No if''s, and's or but's.

On top of that, figure:

Quality engine managment A solid turboYour basic IC/Pipe/WG/BOV/Mani/Exhaust setupAn ignition (MSD) setupAnd periphial stuff (gauges, misc parts, ?suspension, ?rubber, etc)

$10k might seem a little high, but you could easially spend that much building a car like you're doing. If you can do mostly all of your own labor, search for good deals, and plan well- you could probably get the car done for around $6k. No less than that though.

Good luck!

[rid'n solo]

I knew from the begining that I would have to do that. I checked out the AMS Adv. rebuild kit for 2k. I was kinda concerned about the pistons, because I know that you should have a low compression but I thought having a too low compression was bad. For the turbo I thought about going with a Garrett Turbo GT series Universal GT40, 750hp, Comp Trim/Hsg: 88 mm, 54 Trim (0.72 A/R), Turbine Trim/Hsg: 73 Trim (0.81 A/R), 105557 for about $700+. I'm not sure which trim to chose though.

[emperor_lunchbox]

I think that turbo it too big for your daily horsepower goals, 250/300. 250-450 is quite a spread. I know its possible, but you will need to plan carefully. If I were you I wouldnt buy anything until you have talked to everyone and anyone who has achieved what you want. Who knows, you may end up altering your goal a bit.

As said before if you want something reilable with proven performance get the IAP kit. A similar kit could be built for way less, but you seem like the person who would rather buy it and drop it in. Also, AMS is working on a turbo kit, I dont know anything about it, but from what I hear it should be out soon.

you forgot about building the engine and other misc. stuff. Just ask fiz.. he spent something like 13 grand on his car only to have it blow up after 1000 miles (sorry dude... dont mean to envoke bad memories)

[KATwo40]

I'm building my engine right now, and after all the machine work, parts, gaskets, etc. I'll be under $2800.00 for the engine...fully forged bottom, ported head, 240/248 cams, stock valvetrain.

Factor in the other $3-4k for the turbo, mani, WG, FMIC, pipes, fittings, BOV, oil lines/fittings, couplers, exhaust work, injectors, fuel pump, etc., and you're in the $6k range, overall.

I'm not saying that it can't cost $10k, I'm just saying it doesn't have to cost that much.

[Florida240sx]

Curently I got 5k into turbo kit and engine. Then $500 for clutch, $1500 in electronics(gauges safc wideband etc.)I still need lsd suspension and tires.

fiz is right...ive created possibly the most complicated spreadsheet ever, all in the quest of building a 400ish hp KA-T. there is absolutley now way to do it for less than $5500...period, unless you can get quality parts for free. if anyone wants a copy ill share it, but all of the info on it can be easily found with a little time speant searching the forums.

[emperor_lunchbox]

I would be interested in your spreadsheet for comparison. I have created one, but I was severly upset with the prices I came up with.If you wouldnt mind, please email it to me. [email protected]

[superDorifto]

sent...email me if you have any questions.

so..i guess add ~3 grand or so for engine rebuild.thats est. 10g.500 whp isnt going to come out on the stock block w.o something coming out the side.

[lilskyline240]

I too make spread sheets for parts on every build i do...i found it very handy....expecially when you find good prices on a site, you can bookmark it and put it on the spread sheet for furthur reference...

[superDorifto]

and without the sreadsheet, all the little costs that add up to bite you in the *** can be accounted for. i love excel

[hannibal]

OMG, I thought I was the only one that used spreadsheets for this stuff, haha. I'[m sure mine is less complex, as I wasnt planning on building the motor for 300whp.

Will, I'd like to see how your spreadsheet looks.hannibal.jones AT yahoo.com

Wouldnt a ball bearing turbo be best for such a large range of power? It'll be tough to find a turbo that will be efficient at 250whp and 500 whp.

[lilskyline240]

its just nice to see how much you have spent and how much is left to spend to reach your HP goal...

[myRed240]

I also have an excel spreadsheet with all kinds of prices. Would you mind emailing me a copy of yours to see if I've missed anything?Thanks!

You really can't have both, unless you compromise one or both of the tunes. A good tune for 250 daily hp won't be even close to what the tune should be like for 500 track. There's way too far of a spread.

Likewise with the turbo...a turbo that is good and has a reasonable amount of lag for 250-300 will NOT be big enough to give you enough flow to reach 500 whp; conversely, a turbo that is big enough to get you to the 500 whp mark will seem absurdly matched to a 250whp level. There will be a LOT of lag.

As far as engine management goes, how are you planning on switching between 250 whp and 500 whp? The difference between a 250 and 500whp tune are SO marked it seems impossible to have both tunes run well. What are you planning on using? You could use a stand-alone and tune it for 250 whp, and then completely RE-TUNE it every time you want 500 whp, but that doesn't seem very feasible nor practical. There's more to making 500 whp (as compared to 250whp) than just cranking up the boost. A LOT more.

I think you're trying to achieve something unachievable...you'll have to seriously compromise both tunes to make it run well in the large spread between 250-500 whp.

If I were you I'd try and determine, REALISTICALLY, what power level the car will see the most. Why not shoot for an in-between like 400 whp, which would be easier to achieve with a turbo that offers good daily drivability, and could be achieved with engine management as basic as a re-flashed ECU and 72 lb/hr fuel injectors. Have you ever been in a turbo 240 with a decent amount of power? Even 350whp seems absurdly fast...Let's say your ultimate goal is 400 whp and you use a re-flashed ECU and 72 lb/hr fuel injectors....then you could run say 10 psi daily, and 20 psi for track days, but again, 10 psi on an ECU tuned for 72 lb/hr fuel injectors will have you runn quite rich and conservatively (e.g., a lot of timing retard).

It'd be nice if there were some magical switch that changes the ECU tune from a low-hp one to a high-hp one, but alas, this switch does not exist.
