I plan to pick up a s14a in the spring and have an sr swapped into it right away. Let me know what you think of this setup, all these parts will be done at the time of the swap.

1) '97-'98 240sx2) S13 SR20DET3) Blitz LM FMIC4) HKS SS BOV5) Blitz 3" downpipe and some 3" testpipe6) APEXi GT Spec Exhaust7) Metal Headgasket8) Walbro 255lph or 300zxTT fuel pump9) Larger Injectors (any recommendations for size, if I am going to keep the T25 for a while, I'm thinking 550cc might be overkill?)10) Clutch (possibly ACT or SPEC)11) OBX short throw12) KOYO Radiator13) EBC14) APR head studs15) GReddy Oil Pan

After that is all installed and running well, my plan is to turn the boost up to around 1 bar and run like that for a while until I can get the money to swap the turbo. So for now, I'm trying to get all the essentials for at least 350whp done right now.

Do you think, from what I've listed, that I would be able to eventually put on a larger turbo and make 350 horsepower to the wheels.

Tell me if you see any problems with the list, and thing I've forgotten on my quest for 350, or anything that you would suggest changing in my list...

looks good to me. (you might want to consider doing rocker arm stoppers before getting 350 to the wheels.)

Is S13's Sr20det fitted with only T25? I thougt it hade a T28 like the S14,15? The T25 will probably go warm and at max so 1bar seems good.

Some "points".

4) HKS SS BOV. You don't need it. But they are cool ;)5) Make sure to get the "elbow" from the turbo.7) You don't really need it. Atleast not now. But if you have the engine apart. Why not?8) I run 300zxTT fuel pump. Fits great! (and cheep, 80$)9) Probably to big now yes. But right if you change turbo. You could raise the fuel pressure and check the EGT temp. You might get away with it.12) Do you need a new radiator? Is the NA bad? (don't know 2.4)13) Haven't tried but should be "ok". I have Endress CC-X. Great.15) Why not an oil cooler instead?

* Dont forget boost meter, Oil temp and if afford EGT, A/F.* How are you planing on running the injectors? Ecu?

350 ATW is alot! So I think you should need some more stuff if you want a street car, but do this first, it will be lots of fun :)

Yeah, I left out a few minor things: I plan to have a boost gauge and EGT to start.

As for fuel management, I'm not too sure. I could have JWT program the ecu for the "T25" setup and then have it reprogramed later on when I upgrade the turbo. Any suggestions or experience with the upgraded ecus??

I would suggest getting a HKS VPC/S-AFR combo for fuel management if you can find one. The VPC was discontinued awhile back and they haven't released it's successor yet.

Well... I think it a good setup.

But if your going for the big HP, you should change pistols, camgear etc etc. But you can wait some with that.

For the injectors you can get some fuel computer, like Apexi S-afc or Hks. But then there is limitation ofcourse. They are good, but cant to so much more then fuel :)

I'm looking for a Apexi Power FC ecu. Check it out. The best buy I guess... But You maybe have to tune it yourself. Motec is good, but maybe overkill for a normal streetcar.

You can also get a 300zx TT Air flow meter. Buy that and the pump from a dismounter. You can control it with S-afc or Power FC.

And there is 1000 other things you can do if you have the cash, but I think this sounds like a very good begining.

With the VPC, you convert your car to speed density and get rid of the MAF all together. You can also get a chip to put in the VPC that is specific to what size injectors you have. The HKS S-AFR is a much better option for fuel tuning than the S-AFC but it's not as pretty.

Haven't tried the HKS fuel computer so I cant tell, but whats the diffrency? Can the HKS manage new (300zx) afm also? Thought that was a good point for the Apexi.

I don't think that there is a VPC verision for Nissan 200sx? Is there? Sounds good if so.

And if you should get both vpc,chip and afc. A New ecu would be to prefer I think.

The HKS S-AFR has more adjustment points than the Apex-i. They do make a VPC for the SR but it will take some hunting to find the actual unit, harness and proper chip. If you go this route, you will not need a 300ZX AFM.

Looks good...

Get guages, atleast boost gauge and egt gauge, if you have more money I'd get water temp, oil pressure & fuel pressure guages aswell.

EBC... as in a Electronic Boost Controller, which one? ..or as in the brake pads?

In either case.... for boost controller I'd recommend the Greddy Profec B, for brake pads I'd go with Porterfield or Carbotech.

Yeah, I meant Electronic Boost Controller, The Profec B was one I considered and is popular. Do you have any personal experience with that controller, or any other types you would recommend and why?

I've never used any electronic boost controller, my previous car was a turbo Integra and I had just used a Hallman boost controller.

scruf1986 - You never know.... besides, I know there are alot of quiet guys out there that never post that can also gain information from these posts.

Wether the subscribers intentions are are true or false is not the point =)

sledgehammer - I have actually not experienced the Profec B personally, but, lots of friends have them and they work great. I like how simple and cheap the Profec is, I like it because it doesnt have Fuzzy logic, no crazy buttons or crap like that.

I used an HKS EVC PRO on my old Supra and it had sooo many features, I never even fully played with it. Since my old Supra and the sr20det is a single turbo and not a sequential twin you dont have to be scared of getting a fuzzy logic boost controller like the HKS EVC, but I'd still go with the Profec B...

Have someone COMPETENT install the EBC.

The list I made is just work I want done to the engine, so tires and suspension, etc. isn't included. I understand the importance of an LSD (had one on the integra)...but I'm getting up there in price as it is. Is anyone positively, absolutely clear on which '97-'98 models came with an LSD?? Or is it purely an option, that I'd hope the original owner chose?
