dat240zg Posted December 19, 2007 Share Posted December 19, 2007 Alright.. I recognize that these type of questions frustrate some people, so if you're one of those, don't worry about it... For the rest of you, I have approximately $1000 that I can spend on the Z to boost performance. This is seperate from the restoration, so I can finally pick up a few goodies. Anyone want to make suggestions? Keep in mind one thing - dsommers is at this time building a motor that will kick my tail, and so I've got to be ready... As the car stands, I have the following as a baseline: LT1 with ported intake, 30# injectors, 52mm TB, Headers and 3" mandrel exhaust. Brakes have been mildly upgraded to 4 piston fronts and 240sx rears; Nismo R180 LSD and 17" wheels. I've installed coil overs, adjustable T/C's and camber plates. I'm watching a nice Nitrous setup as well as a LT4 hotcam kit. Anyone want to throw another couple of ideas in the ring? Bryan Quote Link to comment Share on other sites More sharing options...

Pop N Wood Posted December 19, 2007 Share Posted December 19, 2007 Bad Dog frame rails. The LT4 hotcam does wake things up, but depending on usage you can go bigger. Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted December 19, 2007 Share Posted December 19, 2007 without decent AFTERMARKET heads or seriously ported LT4 heads and a cam that takes full potential of the head flow your beating a dead horse http://www.malcams.com/legacy/misc/headflow.htm http://www.h-body.org/people/projects/building_lt1/lt1%20info.html http://www.chevyhiperformance.com/tech/engines_drivetrain/cams_heads_valvetrain/0612ch_lt1_engine_build/photo_15.html http://www.customclassictrucks.com/techarticles/0602cct_lt1_engine_history_build/specifications.html http://www.ideasandsolutions.biz/HooverSB/top.html http://www.ideasandsolutions.biz/HooverSB/top.html http://airflowresearch.com/227sbc_lt4.php Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted December 19, 2007 Share Posted December 19, 2007 PM me for my Paypal account info. J/K Interior? Seats, harness, cage... Quote Link to comment Share on other sites More sharing options...
Gareth Posted December 19, 2007 Share Posted December 19, 2007 Keep the money and spend it wisely on something that you'll decide about later. I know they may be burning a hole in your pocket, but time will tell whether you will need any additional funds - that's when the 1000$ you have could come in useful.

dat240zg Posted December 19, 2007 Author Share Posted December 19, 2007 All good ideas - I forgot to mention that when the body was done, we installed the bad dog rails and installed a 6 point cage, harnesses and '07 Miata seats (I'm too tall for other more common racey seats).

dat240zg Posted December 19, 2007 Author Share Posted December 19, 2007 BTW, Grumpy, thanks for the good links - more reading material for the evening! Bryan Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 19, 2007 Share Posted December 19, 2007 Better front brakes (assuming you're using Toy calipers on solid rotors). You might also consider the http://www.wolfcreekracing.com CV upgrade for the R180, if you're worried about breaking U joints. Quote Link to comment Share on other sites More sharing options...
dat240zg Posted December 20, 2007 Author Share Posted December 20, 2007 Didn't know about the R180 kit - honestly, now that Gabe has his parts in line for the rear end swap, I've been considering going with a R230 (and that may be where I put the $).

Bartman Posted December 20, 2007 Share Posted December 20, 2007 Without a doubt...ported and polished heads, and a matching cam if you can swing a little more cash. This isn't where I got mine from, but it can give you an idea of costs and potential results http://www.eportworks.com/lt1.html This is where my heads were ported and polished: http://airflowperformance.net/index.html Quote Link to comment Share on other sites More sharing options...
80LS1T Posted December 20, 2007 Share Posted December 20, 2007 I have the LT4 hotcam kit in my car. It's an alright cam but I am already looking for something "bigger". Bang for the buck its a nice kit but buy better springs as the ones in the kit are marginal for the HC as it is. If you want a little more power get the HC kit. If you want 400WHP get a nice set of heads and a cam that matches them with some roller rockers. You wont get much for $1000 though...

LLave Posted December 20, 2007 Share Posted December 20, 2007 How about, build a turbo kit using a MP t70? Quote Link to comment Share on other sites More sharing options...
dustin280zx Posted December 20, 2007 Share Posted December 20, 2007 How about, build a turbo kit using a MP t70? Costs way more than 1000 for that...I thought i could get by with 2000. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted December 20, 2007 Share Posted December 20, 2007 Nitrous system, cheap power! LT1 should be good for a little 100-125 shot. Quote Link to comment Share on other sites More sharing options...
dts300z Posted December 20, 2007 Share Posted December 20, 2007 +1 on the turbo... just save up another grand or so. Just think how much your going to spend on bottle fills over the next couple years (average bottle fill $27.00) I ran a few a week through mine for a long time but thats just me. Now I'm working on a turbo kit!!! Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted December 20, 2007 Share Posted December 20, 2007 HEADS (get the best you can afford, spend at least 1/3 of the build cost on heads & components on the heads) DISPLACEMENT (within logical mechanical and budget,limits, bigger is amost always better) CAM (must match the rpm range, gearing,displacement,compression, and take full advantage of head flow potential) COMPRESSION RATIO get it built on the higher edge of the range your octane rating will allow, in both the static and dynamic compression ratio POWER TO WEIGHT LIGHTER IN weight is USUALLY BETTER FLOW RATES (try to get everything in the engine too match, the engines designed rpm,displacement and power range) ROTATING ASSEMBLY (spend a 1/3 here, and take the time to think it thru and get the clearances and lube system correctly built) Quote Link to comment Share on other sites More sharing options...
dsommer Posted December 20, 2007 Share Posted December 20, 2007 Oh gotta throw my name in the mix huh? Well no worries the engine I'm building will be sitting on a stand for quite some time before it goes in the car so your $1K can grow in to let's say $2K before my car gets on the road and your's will still be soooo much nicer. $1K for performance hmmmm. ECU chipped/custom reflash plus a NICE nitrous system as stated 100 to 125 shot will get things going. I'd save it until the car is on the road, tuned and running like it should then dump the grand in to it. Just my .02 worth (buy a 90 day CD David Quote Link to comment Share on other sites More sharing options...

From my experience with our GTO a good tune and possibly nitrous. A guy in phoenix I know has a cammed, nitrous, + his own tune (he tunes for AZ Power and Sound) and its pretty crazy. He also has a ~900 rwhp street tune Camaro that he built. Quote Link to comment Share on other sites More sharing options...
