So I am currently in the process of tryen to finish my build on my 95 gsx 7 bolt and collecting part to make the final assembly as quick as possible, And want to make sure that I have mostly everything on hand before starting the assembly.
So far my engine is completely new and assembled with stock 7 bolt crank, stock head, Eagle rods, wiseco pistons, cometics head gasket, arp main studs and head studs. Other parts waiting to go on I have 1200cc precision injectors, new t3 manifold, dsmlink v3, tomei Afpr, new fmic, and a wahlbro 255 lph fuel pump.
Is there anything else that you all can think of for me to get ahold of before trying to get this all assembled?

Thank you

Sorry forgot to mention it but I do have a innovative mtx-l wideband already as well. So far the big things I think I am missing is the oil feed and drain for the turbo, and possibly a tank to rail line with a filter if eliminating the stock fuel filter is even required. Since right now the gains I am looking for is about 375 to 400 whp on 93 octane.

No need for the fuel line or eliminating the fuel filter. It will not be a restriction at that level.

At what point in time does the stock filter and lines start to become a restriction since those are my daily driven goals for the car. But we all know how it is on occasion we wanna play specially if there is more power in the setup to be had.

Thanks again for all the responses

This is just a general answer as there are many factors that come into play here but your single 255 wally and 1200cc injectors will get you to the 500 hp mark with the stock hard lines/filter.

However, there is a pretty substantial benefit to flow if you do upgrade them.

Road race engineering tested the rewired stock fuel pump with upgraded lines and in flowed almost as much as a 190lph fuel pump.

Just some food for thought if you do find yourself needing more flow.

I'm still running stock fees filter and return for what it's worth. I plan to upgrade to -8 nut for your goals you should be fine

Even if you keep the stock filter, provided it doesn't need to be replaced just from age, deleting the banjo fitting line between it and the rail will make for a noticeable drop in IDCs.

Put an M12X1.25 to -8AN adapter in the filter, then run a new line 8AN Rail adapter.

The last time I did this for someone, I had him buy a Male-Female Fuel Pressure Gauge adapter and liquid filled gauge to plumb in also. Great diagnostic tool.

You could also pop a pressure sensor in their to datalog.

Absolutely but who doesn't like a little leaky fuel in the passenger compartment.

Yeah not my first rodeo on building a nice performance car just my first time with a turbo import. Had a twin turbo setup on one of my old foxbody mustangs.

Good friend went 10.71 and made 560whp on pump gas with a street-driven 2G using the stock fuel lines, fuel filter, and banjo bolt. I don't see you running into any restriction anytime soon. :D

Hey-hey-hey. Watch it with the swear words around here.


:p



This is your cue to go look at the place of manufacture on the tag inside the driver's door. ;)

It's certainly possible. I know of another car that made comparable power with a minimal fuel setup. The results are not common though.

The option I described is cheap, basically future proof, makes it easier on the pump and lets him mount a gauge. Just sayin.

-10 isnt to spec for the hx35 or hx40, technically -12 is still 1 or 2mm too small. But -12 is the closest to spec which is 19mm ID. I run the same feed with no restrictor but i checked my oil pressure.

The hx35 and hx40 share the same chra and bearings. Therefore oil requirements are the same.
