PhaTTy Posted March 6, 2003 Share Posted March 6, 2003 Hey there.. was looking at getting 280+ hp in my 280zx N/A .. I have been working with someone on the following intake/fuel setup: Clifford 6=8 intake (modified for torque and L28 hookup) Quad T-body with fuel rails 4 42lb O-ring injectors Microtech MTX-8 with programer and sensors Bosch fuel regulator Now, just this would run me around $2500 but how much do you guys think the power would be if I stuck this on a 3.1L N/A buildup engine. I was also considering a JCR supercharger if it would handle it with the 3.1L buildup or if I would blow something. Any thoughts on this would be MUCH appreciated as I do not want to spend precious dollars that I do not need to. I would love to run 13's in this car but most importantly I want a streetable fast take off car that will run on pump gas.. Any suggestions for the 3.1L buildup or the intake buildup / supercharger would be MUCH appreciated. Thank you all so much for your help and have a nice day!

Mudge Posted March 6, 2003 Share Posted March 6, 2003 On an NA car, it is not going to make you any new power, other than increased engine management. Heads and cam, along with cubes make power. Swap the cam, raise the powerband, and you have some power when tuned. With a turbo you can turn up the boost, or do similar things that you do on an NA car, cam/headwork etc More fuel wont make power in other words, it supports it.

PhaTTy Posted March 6, 2003 Author Share Posted March 6, 2003 I was wanting to go the route of supercharging the 3.1 buildup engine because I am interested mainly in acceleration. How much would a turbo setup cost in comparison to a supercharger setup (like the JCR?).. Let me know! Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 6, 2003 Share Posted March 6, 2003 No comparison, since there are turbo parts out there and they plug right in. Intercooling, not a problem. On a blown setup, your going to fab up everything yourself, and being a pioneer usually is more expensive. Quote Link to comment Share on other sites More sharing options...
fl327 Posted March 6, 2003 Share Posted March 6, 2003 supercharger is nice eye candy though, but extremely expensive, ive seen those camden blowers go for 2000.00 used and still need a rebuild and fab to work on a L motor. you can always make one off a grand prix work, but once again the turbo setup for the same money will smoke it. if youre really interested in some straight line terrorism, do a V8 swap, it will cost a little more to get dialed due to the other modifications, but once its in and putting power to the ground, youll love it.

PhaTTy Posted March 7, 2003 Author Share Posted March 7, 2003 wanted to stick with the L28 but what about a twin-turbo setup??? any suggestions for which turbos/intercoolers and setup? Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted March 7, 2003 Share Posted March 7, 2003 wanted to stick with the L28 but what about a twin-turbo setup??? I hope your pocket book is REALLY deep, or you have mad fabrication skilzzz... To achieve you horse power goals, realistically you simply need the stock turbo drivetrain from a donor car and and intercooler to turn up the boost. Get the best intercooler your budget allows the first time so when you upgrade to get over 280hp (and you will), you won't have to run the plumbing twice. my $.02 Quote Link to comment Share on other sites More sharing options...
katman Posted March 7, 2003 Share Posted March 7, 2003 the next kills on my list have rebell-HOE motors. Ha, that's funny. We call them Re-bomb-oh motors. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 10, 2003 Share Posted March 10, 2003 The turbo is the way to go here because, the turbo parts are easy to come by. The superchargers are very expensive and very costly to rebuild if and when the go out. Mudge is right intercooling is easy as 1 2 3, if you know how fab the pipes yourself. My buddy just bought a npr intercooler and I will be the one to weld them together. You just got to be careful. Dave Quote Link to comment Share on other sites More sharing options...
PhaTTy Posted March 10, 2003 Author Share Posted March 10, 2003 Hrmm.. my dad welds.. wonder if he could do it hehe.. I havn't a clue about fabbing piping or anything but I guess its always time to learn.. Any tips or tutorials out there ?? You guys rock thanks for the feedback so far for all my questions. (btw- what would I need for a 11 second car?) Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 10, 2003 Share Posted March 10, 2003 Twin turbo would be awesome, but plenty more difficult because you would be forced to fab up some headers, intake and intercooler routing as well (I just saw a Porch TT intercooler on eBay). It has been done (haven't seen any cars running yet though?), if you dig around the Turbo forum I believe is where you will find TT header pix, if not I can dig them up or someone else can post the link. If you avoid the TT job then you can run the stock manifold and upgrade to TT later, once you understand the turbo getup a bit better, as far as what kind of fuel issues you will need to take care of, intercooling, and other things to expect. At that point you may well want to pull out the engine and refresh it, maybe go full floaters on the rods as well, better cam setup, headwork, stainless and polished exaust valves, and other upgrades like that.

PhaTTy Posted March 10, 2003 Author Share Posted March 10, 2003 Well I was thinking of doing the TT setup on a the 3.1L buildup (from the stock 2.8) ... What kind of power and drivability are we looking at? I know you can adjust the turbo boost from inside the car but I would still like to be able to run pump gas with those babys boosted up. Ideas/Suggestions and yes TT header pics and intercooler info and pics would be nice as well as detailed info on how it could be done and all that was needed.

Mudge Posted March 10, 2003 Share Posted March 10, 2003 I know you can adjust the turbo boost from inside the car but I would still like to be able to run pump gas with those babys boosted up. Not without buying an electronic boost controller, otherwise your not going to be doing anything from within the car other than driving. http://www.hybridz.org/phpBB2/viewtopic.php?t=18892 Quote Link to comment Share on other sites More sharing options...

Mudge Posted March 11, 2003 Share Posted March 11, 2003 A dual boost controller would be nice, too pricey for me though Quote Link to comment Share on other sites More sharing options...
ZR8ED Posted March 12, 2003 Share Posted March 12, 2003 Whoa!.. reality check here.. your talking 280+ horse.. then your talking all this FI stuff.. then superchargers..then turbos then twin turbo's, and then asking about 11 sec 1/4 Z??? Your all over the map man! You are talking from 5-20K for the range of engines your talking about.. even more if you have to pay someone to do all the work.. What are you trying to accomplish? how do you want to use the car?.. do you have emission requirements in your area?...There is a lot more to this before you decide on HOW to get the 280+ hp you want... 280 + hp from an NA engine.. even a 3.1L will cost big bucks.. heck the parts and machineing to get you to a 3.1 aren't cheap.. and then you haven't even mentioned if you want this thing to last?.. A proper balancing, polishing of the rods/crank, and shotpeening the rods are not afterthoughts, but are critical to making that setup HOLD the power reliably.. $2K min, anything less I believe would be shoddy workmanship, or just plain lack of serious race preping... Actually I think it is pretty easy to generate that kind of hp on a na Z engine.. what is tough is freeing up all the wasted hp... That is the difference between guys running 240hp and guys running 280 hp.. (increasing the VE of the engine).. Think about as freeing up hp that is used just to make the engine turn over... What are your skills?.. whats your budget? A simply port and polish on your cyl heads is not going to give you much hp.. SERIOUS head work.. in the neighbourhood of $1K+++ $400+ just gives you a rebuilt head... And when you do get this motor.. better think of how to stop that rocket! Nuff said.. Now answer some of those q's and come back.. there are a ton of answers to match your particular needs/budget... Quote Link to comment Share on other sites More sharing options...

PhaTTy Posted March 12, 2003 Author Share Posted March 12, 2003 Vee Eight heh.. my dad is a 14 year ASE certified race mechanic and he says the OHC 2.8 can be beefed up to beat ANY 350 due to the weight/design. As for the tons of questions.. I am planning on a brake buildup to stop the thing and I am getting all the machine work done for 100% FREE through my dad who has been doing these things for 10+ years and has all the equipment at the race shop to do. Having a 6=8 intake put on also (free) and plenty more.. It is a nice dream but it is becoming reality every week that goes by as more and more work is being done. Don't want to sound mean but instead of critisism how about some support and suggestions here. I would like to do the job right and so it lasts a while so I would appreciate feedback on what all is needed. The 6=8 intake will either be port injection or using a 4 barrel throttle body injections using (4) 42# injectors and a nice Microtech MTX-8 EFI system. Any suggestions/ideas/comments or creative critisism? Thanks for the input so far and hope I don't come off as angry hehe Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 12, 2003 Share Posted March 12, 2003 Vee Eight heh.. my dad is a 14 year ASE certified race mechanic and he says the OHC 2.8 can be beefed up to beat ANY 350 due to the weight/design. Well you better let go of that thought right now. The L28 N/A is a good engine, but 300hp is tops, and is hardly streetable. A mildly warmed over 350 will easily top 350hp, easily streetable. Consider your goals, and your options. There is a huge base of knowledge here, and plenty of people who can answer very specific questions.
