Non Sequential (Should I)

[allstaruk]

Hi ya guys,

As some of you may well know i am having some boost problems and am getting fed up fixing them, the RX7 is strictly a toy and have a lot of mods to go on soon, also I am in the process of cleaning up the engine bay to make ti nice, at some point I\'m going to go single too, so basically what I\'m saying is, should i go non seqential.

I have a downpipe/Decat/Cat Back so it should still spool up relatively quickly, I don\'t mind fixing the boost problems I have I just don\'t really want to get anymore, the though of getting them all working then a month later them stopping already annoys me.

If I was to go non sequential I\'d do it properly by removing the turbo\'s and having the wastegate enlarged.

So come on guys, pro\'s and con\'s what does everyone recon?

No cons from me mate... Just do it.. best thing ever... you will never have hassel again!  
 It either works or it don\'t....  Simple and sweet..... :Thumbs-up

 Now stop posting and get cracking with it....

Oh, and yes deffo do it properly, it\'s the only way!

From what ive heard you can avoid the lag with driving style, like if youve got a big single. If your on a bit of a run your normally in non-sequential mode anyways.

I\'d probably do it if I was planning on going single anyways, could save you a bit of time and money, if I was keeping twins though would prefer the sequential mode.

Here a recent thread about pros and cons, some info after the initial few posts http://www.rx7club.com/showthread.php?t=596489&highlight=turbos

As I\'m sure you all know I run a T51, ( they don\'t come much bigger on a road car) It does not come fully on line until 5000 revs, so yes, you do have to change your driving style. But it dosn\'t take long and the power is FANTASTIC.
There is a big plus that I had no idea would be out there. If I only drive using up to 4000 revs and 0 boost I get 350 miles to a tank of fuel. Found that out running in the RE Engine, needless to say I don\'t do that but I do know that normal driving I have a good fuel consumption.
Going single is all about what you want as an end result. HTH.

Oh don\'t get me wrong i\'m heading single at some point but I\'ve got some interesting plans first though an some r and d to do so basically everything I\'m doing now means I can just bolt a big single on at some point.

So should I do it? I\'ve got a second set of twins encase I want to put it all back to rights.

Also what sort of cost am I looking at to have the wastegate milled out as thats the only bit I don\'t think I can do.

£500 plus mines getting milled shortly from 25mm to 28 mm

Just to have it milled thats the only bit I need doing i can remove the turbo\'s and do the rest.

I\'ve been quoted less than that by one of out more well known tunrers.

Your plans wouldn\'t involve a T51 " Rules " would it.

[allstaruk]

You never know, I\'ve not finished deciding what turbo yet.

So anyone know anywhere cheep to get my wastgate enlarged?

Call Pip, bet he may have one on the shelf waiting for you!

Do you mean, buy a set of turbo\'s already converted, I\'m not to sure how all this works what bit is enlarged it it on the turbo\'s or does the wastgate come off, any explanation would be great.

I went non sequential and much preferred it matey.

Just a little off the subject, can you go N/S on a stock engine?
what i mean is no porting or map?:xconfused

I guess that you couldnt !!! as you would have to tell the ecu to add more fuel to get the most out of it?

or could you???...........

you need the car to be mapped to go non seq..and youd get terrible lag without a catback at the bare minimum.

I was toying with the idea of non-seq but it only took one ride in a car running sequential properly to tell me that was a bad idea! I personally wouldnt bother...thres so many fds out there which are iehter single or non seq...its soon gonna be rare to find an fd runing seq stock twins!

You shouldn\'t need porting to run non sequential but I will need a map, I\'m gonna give it a go I think along with everything else that I\'m fitting to the car then trailer it down to reworx and get it mapped.

 That actually works without hassel all the time! :Tongue1
