Boost designs turbo kit?

[nismo_12]

I'm thinking about either the Sr 20det swap or turboing the Ka24de. I own a 1995 240sx and was wondering how reliable boost degins turbo kits are and if anyone has any suggestions or comments on any other turbo kits made for the Ka24de thanks in advance. I'm new to this bored but i really like how it's set up. Thanks again.

welcome to nico

there's somebody here with an S13 and a boostdesigns stage 1 kit with FMU, pretty sure he's been runnin it for quite sometime...

Also If i decide to turbo the Ka would it be a good idea to port and polish the head and buy forged pistons and so on? sorry for all the questions new to nissans and just needing answers Thanks. I owned an RX7 before this car and it was almost impossible to find anyone with knowledge about the rotary

The ka24de can handle 350rwhp safely as long as there is good tuning at 400rwhp the pistons rings go.So if your setup is going to be under 400hp you don'tneed to upgrade your engine...however it would be better to upgrade pistons if compression is low.What's your goals for this car?

[nismo_12]

My goals are to have somewhere between 375 and 450 rwhp. It will be a daily driver and do some drifting on the weekends. Any suggestions on what turbo kits are best? I looked at boostdesigns website they seem to sell alot for the Ka24de but how is the quality and how is the quailty of KA24de.com products. Thanks again for your help in advance.

375-450 is gunna be hard to get reliably in anything. i'm new to the turbo thing but i don't think much of there kit is good up to that kind of power

stage 2 made 301rwhp @ 10psi

Yeah Im one of the guys with the boostdesigns kit on my s13. The intercooler piping is a pain in the butt to figure out, plus you get no instructions....at all. PJ is very very hard to get in touch with, if you have questions.....which you most definitely will. You can run a safe 8-10 psi with the fmu, but then it becomes worthless. Right now, I have a 1993 kat with the boostdesigns kit and a 1997 s14 with a s14 sr. The 1997 will be completely finished in about a week. Ive been waiting on parts for forever lol. So far, believe it or not, the sr swap was easier than installing the boostdesigns kit. The piping took forever to cut and weld and the freaking downpipe doesnt bolt up to anything but their exhaust, so this in turn made me have to wait in line for two weeks at a muffler shop to get a 3"pipe thats 2 & 1/2 feet long. My wastegate from boostdesigns was supposed to come with a 8lb spring....lucky for me it came with a 14.7....1 bar spring which caused me to over boost, blow off a wastegate hose, and couldve blown my head gasket.....im not sure about the head gasket yet. Ive got to get that checked, but my car is running really stupid. All in all, for 2k the boostdesigns kit is worth the money, but I think they get in too big of a hurry there. If you check everything you get (very throughly) then you should be ok. I think Im getting around 250whp or so at 10psi. Thats what my butt and back tell me (its usually pretty accurate bc Ive been in many many high horsepower cars). Thats not bad for spending only 2k on the kit, but I didnt have to pay labor since I own a body and mechanic shop. Good luck on your embarkment and be sure to let us know how it goes. We all like pics

FMU is said to be good only to 10 psi there is people running more although i dont advise it. everyone knows our DP is for our exhaust systems and is clearly stated eveywhere on every nissan forum out there it was never meant to bolt to any other setup. i have been hard to get ahold of becouse of the merger sorry.

How close is it to the APEXI N1 exhaust

[D1 guy]

The apexi N1 likes about.....well almost 3 feet and will have to have a wierd angle at the end to bolt up to the bd downpipe.

[GEO]

so like I nee dmore then a test pipe.. lol

[D1 guy]

pretty much. Youll have to have a shop build you a pipe...no doubt about it. Sorry, but thats just something that has to be done when buying their kit. Boost designs should offer an adapter for their downpipe. They could make money that way for people who are wanting to keep their own exhaust. Now thats a good Idea if they arent going to change their pipe.

sorry for being a retard, but what is FMU?

I personally would be happy with about 250WHP to start with. Can this be done with a stock KA in good condition? IE no cams or head work. I will be rebuiling a KA IE new headgasket maybe rings and stuff, the usuall so the engine will be good.

for the 250 to 300 WHP range will i need to do anything more than a SAFC plus injectors for fuel management?
