Next month I'm purchasing a JDM motor and tranny and was wondering what I should do to it. I blew the old motor by turning the boost up too high like an idiot. Not trying to have it happen again. Just need to know what I need to get my hp up to 350 running safe.

On my blown motor
1. Full 3" turbo back exhaust to dual mufflers (canister about 6.5 " and tip 4.5")
2. Garrett turbo a/r .50
3. Greddy 3 row fmic with 2.5" piping
4. Greddy type RS BOV
5. Apexi S-afc2
6. Apexi AVC-R
7. removed air pump
8. buying a new stage 3 clutch
9. HKS Intake
10. Fluidyne Radiator

Im in the middle of purchasing ported TB and intake and was wondering if I have to Upgrade my injectors and If so whats the best setup to go with. Also do I need to upgrade my ignition b/c I don't have much money right now

550cc primaries will be fine
720cc + for secondaries
You don't ignition yet, but you get like Jacob FC2000 for less than $200, also you may want a FCD otherwise you going to be hitting a wall after 8psi of boost. + porting your stock turbo wastegate.

*you will not reach 350hp with a stock turbo. At most maybe 300-320hp.

 

well without sounding harsh, a little searching will get you some valuable information. This has been covered quite a bit, but lets start out with what you need: first of get the jdm motor in and running. it is going to be crucial that the jdm engine be total gone over prior to expecting to run it hard. after installed and all possible leaks tended to you need to do a compression test. most people are going to recommend a rebuild right off the bat. even though its a "low mileage" engine, you never know how it was treated prior to your ownership nor do you know how long it was sitting somewhere across the ocean then on a container to get here. well if all is well and there arent any bad coolant seals or low compression, then you could go from there. your current arsenal is a great start, however you need to take some precautionary measures. fuel system is going to need a pump and at least 720 secondaries to be safe. you also should consider a chip for your ecu. search for the rtek (either rtek 1.5 or 1.7) would be great upgrades. they will further assist you. a wideband o2 sensor is an absolute must if you are going to be attempting anything of this caliber. the original computer is stupid. it doesnt have learning capabilities and can only adjust so much for your increased performance needs. the ignition as long as its working properly should be more that effective. 350hp may be too much to expect without a standalone or some other type of engine management upgrade. that should get you started.

There is no bumping in the 2nd section. I pretty much summed up on what you need/

 

If you want 350 and you're on a bidget go for a bnr stage iv. That and an rtek and fuel upgrades.

Clean the carbon out of the new engine and do what everyone else is telling you to do.

 

if you want like 350rwhp you may want to look into a EMS, BNR stage 3+ with 1000cc + for secondaries. Also you might want rebuild your motor for it. Such as Street port and 2peice 2mm apex seals or even 3mm.

 

Get 3mm apex seals, because they don't seal as well, and j-rat pulled 437whp on a stock engine with 2mm seals.

For an EMS you could always go with megasquirt, A little more than an Rtek2.0 i think.

I wouldn't personally trust the JDM motor, but if thats what he wants to do he should go for it.

 

megasquirt is the cheapest but you need to assemble and program everything yourself.
I rather do a full rebuilt with street port and 3mm apex seals.

I rather spend a little more for something better and do it right.
