So I picked up a used turbo kit not too long ago, consisting of a Garrett t25, greddy top mount cast manifold, Godspeed intercooler, shitty crush bent ic piping, hks ssqv, autometer boost gauge, random oil lines and fittings, and some 1.8 injectors. Now I know it's not complete, obviously, missing a downpipe, real piping, fuel management, and most likely will be getting a mspnp. But my questions are will this turbo build enough boost for a noticeable difference in power? I know it spools super fast but I've heard it also cuts just as quick. Also do the 1.8 injectors push any more fuel than the 1.6? Or will I need to invest in some bigger ones? Say Around 8psi Is what I'm planning for. I also know if I keep this turbo I'll have to make a custom downpipe because the flange is flipped, from using the top mount manifold. Any criticism or help is appreciated, thanks for the input in advance.

 

you will notice a difference with the T25
I recommend getting some Rx8 injectors 440cc or some ev14 based fuel injectors, 400cc+
those 1.8 injectors won't handle too much before being maxed out, mighta s well sell them and get some bigger ones if you plan to go standalone

 

Is that the standard GReddy turbo (TD04H 15?)

If so, you'll have some fun with it, but you'll need to keep tinkering.

Consider some more fuel flow - I went with a pierburg, 1.8 injectors (need to go larger, but no ECU yet)

 

Don't believe the Greddy kit has a T25, so either it's not a T25, it won't fit the manifold, or I'm wrong.

Power doesn't "cut just as quick", it'll just stop building. Great turbo, and with the power you can get from MSPNP and proper injectors, you will hopefully notice when the power doubles.

 

Stupid question is stupid.

yeah when you make 220rwhp and pull along with 90% of v8s no worries im sure youll notice it..

I'd say keep the 1.8l injectors, get a FPR, and a timing retard box of some sort, and have a solid 8psi set up that will be very reliable, and dead nuts simple. You didn't put much effort in to your post so I really doubt you will put the effort in to turbocharging your Miata.

 

I didn't buy a greddy "kit" it was peiced together by a previous owner, it has the 300zx t25 and I'm pretty sure that's the only turbo they came with.

 

I edited your post. You do NOT want to start calling people dick bags. Read past our insults and sarcasm to the true meaning of our posts, we are trying to help.

You used poor sentence structure in your original post, which, despite your thoughts on whether or not that is important on the internet, does make or break your post's chance of being easy to read.

Since Bond had this same thought, he conjectured that if you are not willing to put time and effort into a post, you most likely will not put the required time, effort, and money into a proper MSPNP setup and tune. Hence his comment about bandaids, which, as he said, are indeed good for a solid 4-8psi setup.

 

Ah I see, I'm sorry for overreacting. I assumed he was just telling me to blow up my motor.

 

You know what they say when you assume things
