Yes I have searched before I get flamed. I have a few questions about the non seq twins?

1. if i want my non seq twins to be fully spooled by umm 3500rpm what all mods will need to be done..
so far I have ported wastegate, rich mans modded twins, full 3" exhaust open, intercooler upgrade, intakes.. will a lightweight flywheel help out? or anything else I am missing?

2. since the twins will be less restrictive are they more efficent at higher boost levels and or more stable? meaning is it more safe to run them at say 15 or 16psi on a daily driven car?

3. finally is 350whp feasable on non seq twins running a stock unported motor with full bolt ons or majority of them at around 14psi?

thank you in advance..

i kinda have an answer for #3 but the search never said how much boost was ran and mods etc to get over 350whp. just that it went over 350.

 

I do not remember sending a set of turbos to Peoria .

 

why would u have? i did the work myself with a drimmel for the porting, and the rich mans mod ill be doing as soon as i find out if i can reach boost where i want it or if i should stay seq... im very good with a welder.

 

Garco was saying that he didn't send turbos your way since he kind of coined the whole "rich man's" seq thing. He's just poking you.

Sounds like a good list of mods for getting the lowest spool rpm without cracking into the motor (eg streetport etc). I don't think the flow mods are going to change the restriction enough that you'll want to run higher boost than on typical twins, so I wouldn't run 15-16 daily without meth inj etc.

 

hey heidihi if gains on non sequential are good maybe you can help me with converting mine as well =)

 

Ahh thanks Prophet.. and to garco im sorry for sounding rude I was just ignorant so i appologize to ya man! and ill stick to 14psi for my boost levels.

xCxH-- heck yeah man ill help mod ya if we like myset up when its done ill swing up and take ya for a ride in it or maybe u can go with when Steve Dynos it? i plan to have my car up and running early september but I wont have a tune till november when steve kan is somewhat local.. then ill get a full tune but till then I will just be putting around town getting miles on the motor getting it all broken in nice and checking for leaks and so fourth etc..

from what i understand its about average to gain about 5hp by going to NS twins just cause there less restrictive.. but is this the absolute fact?? No its just what ive read about them..

 

alright what day you going up to get dynoed

 

I've done the whole conversion and love it pulling strong at full boost by just over 3000rpm. I've street ported my motor tho, but full 3inch exhaust and HKS a/filters and ported intake manifold too along with all the required non-seq mods like wastegate ported too.
It's definately worth it and much less rubbish around the turbos that can go wrong too. Simple power.

 

since no one has answered this part, i don't believe you'll see 350 at the wheels with your set-up on a stock port motor at 14psi. i had a ported motor with a similar set-up and made 318 with a steve kan tune on a dynopac.

 

ohh man its in late november after thanksgiving.. viking warhammer is seting it all up. we have plenty of time to plan the trip.. im planning to drive there the day before get a hotel and get tuned then drive home!

 

dang i thought 330hp was attainable with 13-14psi on the seq system with minor bolt ons.. maybe im thinking was off??

 

if you searched there is a ton of info on all those questions. anyways:
2)yes but u can run 15psi on seq or non seq
3) yes easily

 

No problems , typed in jest , if you you did all the work that I do on your turbos,manifold ect then you will see boost well before 3500 rpm . The job I do on the castings takes at least 1-1/4 lbs of welding rod ,more if the cracks are really bad . if you did it all you will need to put the prespool door in the wastegate and open the hole bigger than the stock door will cover .Good skill to you .

 

why go nonseq is the better question here?

 

The Rich Man non mod gives the car better turbo flow faster spooling than normal non seq and less problems to solve . My car is more fun to drive, easy to maintain and looks good under the hood with out all the vacuum lines and other junk .If you wont a ride come on and just hold on .

 

My design and execution must be good as I have never had any problems with the turbo system that has been in there for several years, BNR built the units, one off ,and my Rich Mans non seq mod .Of the ones I have done for customers no one has reported not liking them , or the way their cars run .

 

so do you remove material also besides the flapper and around the wastegate?

so far thats about all i did to make it non seq? i didnt have any cracks thank god prob cause it was an extremely low mileage set i have.. should i be doing something also to get a lil extra spool time?

 

does any one have a link for this to make it non sequential

 

this pretty much answers any questions people can have. bookmark the site:

http://www.fd3s.net/non-sequential.html

 

thats the site that I used when i modded mine.. the way i was understanding more was removed by this thread.. but if that site is everything that needs to be done then my twins are fully modded..

 

A part of what I do to the castings can be seen on the following ,the pictures do not show all that is done . http: //www.blackgto.com/rx7/turboes/garfinkle.htm

 

This is the walk through I used off of the RR website, minus a few changes (eg. MBC etc). It's pretty thorough. I had a fully functional seq system when I changed over and I certainly won't be going back. I love it.
