Help me spend money..

[CadetLD]

So my tax return is coming soon and the majority of it is going into the coupe. Im going to be spending about $1000 on it but not too sure what to spend it on. The car needs a clutch BADLY so that is the first priority. Also Im in need of a new BOV so thats another given. Lastly I'd realy like to get a tune but I dont think I can aford it all with the money left over. So with that said, I need to start gathering parts for the tune aswell. Now my question is what would you do with the money? What parts would you buy and why?

Heres a list of what I have to work with. If its not listed assume its stock.

CA18DET, S15 Spec R T-28, FMIC, MBC, Walbro 255, Blitz SS BOV, Blitz Access ECU, Spare stock ECU, Tube Ex. Mani, DSM 440cc Injectors(not installed), turbo back exhaust,turbo timer, boost gauge.

Heres a list of parts I have chosen so far so please if something sucks in this list let me know.Spec stage 3 KA24 clutch. $300 (apparently they work on CAs?)Blitz DD Bov $200Welded Diff $50SARD FPR $135SAFC II ~$250

Dont know what numbers to expect but I think the clutch I chose should hold up to some good abuse with a CA18 dont you think?

Sorry if its a bit long winded, and thanks in advance!-Shane

SPEC makes CA-specific clutches.

Screw buying a BOV new, just eBay it up for a used one for like $60

Spend the rest on a tune. Your car would be pretty fast with a tune mang.

[Liquid_Neon]

paypal me all the money u cant find a use for, trust me... ill take good care of it

[Reno]

and if that doesn't work, you can pay pal me the rest.

[r34 gtr]

You know, with some bigger injectors, you could make it to that realm of 300hp glory everyone wants from their CA. Only difference is, you are already there man.

Spec stage 3 CA18 clutch. $300 (Spec make CA specific.)ebay Bov >$100Welded Diff $50SARD FPR $135SAFC II ~$250 err noNisTune ~ $400Having a very quick CA18DET ~ Priceless

Fixt.Wish i could get a Tax Return

Here's how I would spend the money.

Nistune - $500Get Spare ECU socketted - $30Used/Ebay BOV - $50Non knock off FPR - $125Clutch (spec or Centerforce) - $300

OR

Used SAFC 2 - $150Socket spare ECU - $30Used/Ebay BOV - $50Non knock off FPR - $125Gently used super single OGURA/OSGiken/ETC SR clutch- $500Z32 throw out bearing for clutch - $30Junkyard J30 VLSD $150 (max price)New gear oil for VLSD $15

If you get nistune installed I can email you a .bin file to use. I have an Impul tuned .bin file thats tuned for upgraded stock...you can use it as your OEM basemap and modify it in Nistune for your setup. I also have a chip burner that I could burn you a chip with if you didnt use Nistune but did socket your ecu. It's in storage, I'd have to dig it out.

Wow, thanks for the feedback guys! I had totaly forgotten about Nistune, Im going to be looking into that. Now, let te explain why I chose the parts I did (Im not challenging anybodys comments here just trying to save a few bucks) starting with the clutch. I know Spec makes a CA-specific clutch but they are also more expensive comparativly to the KA clutch. For the price of the CA stage-1, I can get the stage-3 for the KA. If they fit up just fine by removing some dowel pin then why not save some money? This is just what I've read down the grapevine so if theres more to it than please let me know. The BOV, I refuse to get some leaky, slow opening, knock off BOV. Sorry but I loved my old BLITZ SS untill it started leaking after years of use. I found the new DDs for about 180 after shopping around more and besides I wount have to change flanges for another Blitz unit. 300hp would be sweet, realy sweet. What kind of injectors and internal mods do the 300hp club usualy have? That sounds like alot for a 1.8 to last any period of time. Please give reasons for the parts you chose over what I have listed. Thanks a million guys, your insight is invaluable! -Shane

Z32 throw out bearing for clutch - $30

Those are $40.08. I have the invoice from the steal-ership in front of me. Just so you know. Part # 3050245P00.

All you would need is some 550cc injectors and a n60 or n62 MAF on top of what you have, and you would be good to go. No internal mods necessary, and you shouldn't have any reliability issues so long as you have a good tune.

[CadetLD]

Dosnt Spec include a throwout bearing with there clutch kits? Or are the z32 bearings tougher or somehting? If they are then Ill get one too because the throwout on my current clutch started making noise a bit before I noticed it slipping. Also I found these on ebay.

http://cgi.ebay.com/ebaymotors...ories

They are pretty cheap compared to alot of other brands seems like. They have them all the way up to 1000cc and come with a 1-year warranty. Are injectors one of those things I can get knock off parts for or should I go with something more popular like Nismo or SARD? Thanks again fellas! -Shane

[r34 gtr]

How about you man up and get some of these? http://cgi.ebay.com/ebaymotors...A1318

Then you could sell the other four and essentially get them for free, or even make money, depending on how much you buy/sell them for.

If you want to wuss out, here are some 450 DSM injectors for $80 http://cgi.ebay.com/ebaymotors...A1318

The point is, if you take a little time to look around on eBay, you'll find some really good deals. Just because it isn't JDM tyte, doesn't mean they will not perform wonderfully. I got my 510cc evo III injectors for next to nothing off ebay, and they have served me well.

Search major brands like Bosch, Sard, Denso, etc. and you'll probably find some brand new for very little money, relatively speaking.

[CadetLD]

I dont know what to look for though. Thats why Im asking you guys. I already have an old set of DSM 450s but if thats going to be the "bottle neck" then I wount use them. If they will support 300hp then so be it. Trust me, I dont care what country the part comes from or what they are ment to fit originaly as long as they fit my engine, work, and dont need to be hard wired into my harness. Those mustang injectors, I dont know what im looking at lol. One question though. Say I found a good deal on some larger injectors localy like 800ccs or something, but they fit. Could I use them still and just tune so they dont open as long? Or would having injectors matched to my HP goals be a better idea? Just asking because if somehting like this shows up in the local classifieds ill scoop them up if it will work. Thanks again! -Shane

[r34 gtr]

Huge fuel injectors is where its at. If you get a screaming deal on some 800cc injectors, go for it. Low impedance top feed is what you need. Anything of that sort will work fine.

Best bang for the buck, used Evo IX 560cc injectors. Watch out for ebay injectors like the Siemens injectors above, those injectors are sold individually but not advertised in an obvoous way...so they are $100+ for each one. They probably try to trick you into buying one....then when you get pissed that you didnt receive a full set (4, 6 or 8).....they sell you the other 3, 5, or 7 you need at a discount to "make things right"....still coming out ahead on the sale.

Remember, when installing used injectors you will want to buy new pintle caps and CA18DE O-rings for them. You COULD use DSM 450's but you'd have to turn that FPR up to about 61 psi from 43 psi....and they would be about 80-90% of max duty cycle (if I remember correctly).

If you did buy huge injectors, Nistune allows you to change the size AND lag time. Best thing to do once you've purchased the unit is log into the Nistune board and ask the smarter folks on there to help you find the correct value to plug into Nistune to get this lag time correct for your setup. For a BOV...I said "used" because I would rather have a good condition used brand name one than a new chinese knock off. That being said...the rubber inside the diaphrams (even brand name) does wear out....so.....buying a new and trusted (brand) one (or new and never installed from the boards) might be the safe and economical bet in the long run.

Z32 TOB's are larger than S13 TOB's and work....and the larger something is...the better it dissipates heat and the wider the load can be spread over it. That's enough to sell me on it.

Clutches....Keep in mind, a stock KA is like 135hp...stock CA is 175hp....and "stages" are usuallly just a percentage HP (or torque for a better measurement) handled over what the OEM clutch can handle....so if a "stage 1" clutch handles 25% more torque than OEM and a "stage 2" handles 50% more......a stage 2 KA clutch would be rated to 202 hp.....while a "stage 1" CA clutch would be rated to 218 hp. See what I mean?

Wow every reply sheds a whole new light on things for me. I wish I could contribute to the site like you guys do but I would only be the guy stating the obvious haha. You all have been so helpfull and patient with my questions, THANKYOU!

...just had to get that out

Evo injectors...hmmmm..I could probubly find some of those localy pretty easy. Good idea! Not to sure what to do about pintle caps though but I'll cross that bridge when I come to it. I think I misread you about the ebay BOV, sorry. I know a few bucks can be saved there by geting a used one but, for parts that are designed to wear out over time, Id rather just get a brand new one and not worry about it for a long time. It took me a week just to figure out that my BOV was leaking internaly at idle lol. Cool beans on the z32 TOB, Ill make sure to order one when I get my CA clutch. I never thought about the "Stage#" being relative to base HP, good call. Thanks again fellas!-Shane

spec stg3 clutch, $300.vlsd ~$350(ebay)set of the lower grade megan coil-overs. price varies, but do ittt

[r34 gtr]

^coild would be the bee's knees, but trust me, if you buy one thing for your car make it a tune. Not having a tuned car is the sh*ttiest thing ever. Trust me on this, my car is never tuned.

How about the parts counter at the Mistu stealership?

=)

[bentvalves]

be weary of those venom injectors on ebay....google venom / tlfperformance and see what Supra guys have to say about them.

I have a set of 660's in my garage that I look forward to flow testing sometime to see the numbers myself.

[lucky1.8]

I agree; use caution with vemon. My friend purchased them for his turbo 280zx. We flowtested and got diffferent numbers on each.

[bentvalves]

you dont happen to remember the numbers do you?

[lucky1.8]

sorry ks i don't; it was a few years back. Next time I talk to him I ask if he does.
