SMIM question worth it on my set up ?

[awdmonster1904]

Here is my mod list

ALL STOCK 7.8to1

FUEL:
RC1200
walbro 255
REwire kit
Aeromotive AFPR

ELECTRONICS:
ECMlink "lite" V3
AEM wideband

HEAD:
Crower springs
Crower TI Retainers
Ferria 1mm OS valves
HKS cams 264/272

TRANSMISSION
all stock gears and diff

TURBO
"FRANK 2 turbo" old school 20g TDO6
42lbs of flow at 25psi
PR intercooler short route
Gready type S
Dejon intake 2g MAS
slowboy racing manifold
Tial 38mm O2 housing rerouted


My question is it worth the time and money getting a JMF OR Magnus manifold will the added flow help in efforts of making it "91 friendly"
I would like to make my set up 91 oct friendly When i was on street tuning with my friend I was 25 psi 12* peak timing no knock it pulled really strong
this is still on the stock manifold.

Another question What makes a efficient pump gas set up I know there limited amount of octane i can play with being CA piss 91 But its also convenience to run 91

I have the option to run E85 I have the set up for it already
but there limited to the number of E 85 stations where i can refuel on a long trips I love E85 it works wonders but i just wished it was more available in California
Please help me with some input


thank you

I figuere it would especially on top end but my other question "would it make it pump friendly" with the added flow

It will be if you get the street one, I know someone who picked up 40whp using one. You have a decent amount of mods, I'd say do it.

What he said dont go over kill with a race manifold,stick with a street version.

The JMF drag manifold gained whp in the midrange and torque while spooling the turbo faster vs the race manifold. The street manifold is very similar to the race manifold except for plenum size. Since the drag manifold gain MIdRANGE, and is MUCH larger than the race manifold, my suggestion is to skip the street manifold.

The race manifold seems like overkill for his mods.

IMO it wont be beneficial. Very little difference. Guy here added your same cams and a SMIM to his 16g car that was flowing around 40lb/min. He gained zero on the dyno and was very upset with the performance. I would spend all that extra money on a new turbo, something that will flow better. That will give you more gains IMO.

Just to add I dynoed my car the same day and made the same HP and 20lb/tq less than his car. We are close to the same setup except he had a SMIM and 264/272 cams.
