do you have a 240 vert?
vert? probably some lingo I havent got yet because im new to these forums???
Hey Im new. Obviously. I am here because I recently became very serious in buying a 240 about the cars when I find one to buy.
I originally wanted a LS1 Trans Am Turbo, still do. But I decided it may be a little cheaper to do what I want in a 240.
I want a Coupe version(not the hatchback, dont know the different models). What I would like is a nice looking car so paint will be a must unless its good and some rims not into ricing it out. I would like atleast 400whp, with a road race suspension. It will mainly be a fun car for cruising, it will see a lot of road racing/auto cross and very minimal drag racing.
Well hope to learn lots. First I would like to know how possible my power goal with reliably is and much dinero I would be talking(roughly).
Well, you can price the stuff yourself unless someone else wants to chime in on it but Ill tell you some things I would recommend for your needs. The turbo I'm going to list would probably be a good one for you because it can produce a little more than 400whp with a good tune and you will see that 300hp is still extreamly fast in a 240. If you ended up going with a larger turbo you would most likely end up with some lag which you wouldn't really want considering your needs.
A sr20det for starters. Probably go ahead and get better pistons (cp, wiesco ect.) installed just for the reliability factor along with putting arp head studs and a cometic head gasket in as well. Stock rods should be fine. Actually a completely stock sr SHOULD be able to handle 400whp although at that point your nearing how much hp you want to reliably run on the stock sr and a simple tuning mistake can cause engine failure.
While the engine is out go ahead and install a greddy intake. It seems to clean up the engine bay and I heard it more evenly distributes the air to all cylinders more evenly helping with the tuning process.
Throw some 74# injectors on that and either a hks or jgy fuel rail on there for better flow.
Get a adjustable fuel pressure regulator (maybe nismo or other)
Get a turbo manifold and bolt a gt2871r turbo on it.
go with all new exhaust pieces, all of them being 3" from th outlet, downpipe, test pipe, catback
Get a racing radiator (koyo or other) made for the sr. Put electric fans on it and nix the clutch fan.
Get a front mount intercooler and piping kit. (greddy, hks, other) and a decent blow off valve.
lsd, (j30, 180sx) and the axles that go on it.
Upgrade the brakes to z32 because they are cheap, effective and easy. Don't re drill them for 4 lug either, do the 5 lug hub while your at it so your rim choices are easier also.
You might want an oil cooler also. (i want one) its on the to do list.
Get a light weight flw wheel (not necessary) (jgy, enjuku)
Get a good clutch that can clamp 400+ whp. (they can be a pain in traffic)
Now in the engine management catigory your looking at about $500-700. I have a jwt and would have liked a user tunable one. (greddy, aem)
Get gauges that will let you know whats going on such as a boost gauge, afr gauge and a fuel pressure gauge. I would like to have a oil temp gauge too but I dont have one. Go for it.
Most of the things I listed are things I either have or would like to have. I have a more detailed list in my first post in this thread. The b&m shifter in nice too!
The reason I stayed pretty close to my setup is because Im supposed to have somewhere in the 400 hp range and Im sure I do after driving this thing! Ah,I almost forgot, your going to need a good fuel pump. Most commen is a 255lph walbro.
I have whiteline swaybars which I believe are adjustible but I have really looked into that too much. I would recommend a better suspension than I have but I dont know how soon Ill change mine. Im happy with the sway bars but I would like more adjustibilty with coilovers. I just have tein lowering springs but I may just look into dampners to add to them.
Hope I could be of some help. I had no say so in the build in my car either. It was being built for someone that ended up not being able to pay the full bill so I picked up the differnce so I really cant complain about some of the stuff that "I" didnt need or like or that didnt suit my taste as well as it could.
After driving a s13 with as much power as mine has and a few completly stock ones, and some with a stock motor but some good suspension work, I think 300-375 whp is actually perfect.
