critique my DD re-build.

[Boosted6]

I just bought a 1991 talon awd auto.
It will be my summer car,mostly a daily driver. The motor has nasty blow-by,so i will perform a rebuild.

Please give me your $.02 as to what would be a better/smarter way to rebuild the motor:

The car is an auto, has a IPT re-stall converter. a garrett gt-30 turbo 50lbs/min.
Will either run pump or e85,not sure yet.

parts already in hand:

dsmlink v2.5
ets race fmic
all supporting fuel mods and 1000cc injectors.
all maintenance will be taken care of at time of rebuild.

Option 1:

OEM rebuild and stay on pump gas(93oct)

Option 2:
CP 10.5:1 pistons/eagle rods and tunne on e85


What would you do? and why?

How much power are you trying to make?

 

[Boosted6]

I would be happy with ~320-350awhp.

Both options with that turbo would be capable of 350hp, option 1 would be much easier of course. But why not meet in the middle with around 9:1 compression? That would keep pump gas on the table while still gaining a good amount of compression.

I'm also not familiar with V2.5, does that version include access to the DA tables?

OP- oem rebuild should easily handle that power level. But going forged leaves the door open to more power, so keep that in mind.

But if you really only want that kind of power, I think an FP HTA68 would more than suffice, and it is 100% bolt on, so you can keep that stock manifold if you want

With it being a DD I question your choices of parts. Why such a large turbo, why e85 on a auto. I would stick with the KISS rule. The lag is going to drive you crazy and the daily trips to gas station. As stated 9:1 comp, FP 1,2 cams, stock intake and a 16g will meet your power goals and make it a fun DD.

Well, if that's the case then I'd advise upgrading to V3 for more precise timing and fuel control. Otherwise I'm not sure you could take full advantage of E85.

Good advice here. I absolutely loved my Small 16g for street driving, especially when running E85. With nearly instant spool and 300-350hp on tap it was very fun.

That is some serious overkill for only 350whp, heres another vote for the S16G.

Stock rebuild

ECMLink V3

Some ID1000s

Rewired GSS342 pump

Replace the stock fuel filter and banjo bolt'd line to the fuel rail

Manual Boost Controller

HKS264, GSC S1, FP1, etc for cam

Switch to E85

Car already has the GT-30 turbo. It's an old SBR 30-11 bb turbo. has HKS 264/272 walbro 255 rewired,1000cc injectors, s.s fuel filter,link v2.5. I don't really wanna do too much more than this setup. Since i'm going to tear it down,i figured either stock or get some much higher CR pistons in there. Looks like there's no point in spending all the extra $$$ for what i'm seeking out of this car.

Plenty of people making good power on e-85 and V2.5

No doubt about that. But with V3 you can make changes to specific points in the DA tables while V2.5 simply adjusts at RPM points. Those fine adjustments allow for a much more detailed tune. Once I stopped messing with the sliders and started using the DA tables, my setup not only spooled faster and made more power, it ran smoother overall.
