Curious to know if anyone has been running a sinlge making 450 plus for over two yrs time w/o problems?

Matty is considering going single

A3ON7

heard that single turbo boost lags a lot compare to upgraded twins.

matty

i am going single. enough of the bs...been putting this off forever. going t78. i am not sure if i am waiting for winter to do it though.

i made up my mind the other night...but after watching crispeed vid that was the icing on the cake. Going for over 500rwhp on race gas.

As long as you pay attention to the right things you will have a solid car. I have customer cars going on 5yrs with a single. Those are running anywhere from 380-450whp on pump gas. You should be fine, just do it right the first time and take your time, and find the right shop to do the work.

matty

i am gonna have ray wilson at pfs do it. i wont skip out on anything! Care to give some advice as to what it means to do it right the first time?

Don't cry about lag... at least until you feel the power that comes after it.

I see boost late as all holy hell... you'll be able to take nap before my turbo spools up.. but when it does... oh damn, better hold on.

Its all driver preference... I don't mind lag.. cause I don't street race my car.. so for the track, lag is just fine since I power shift and keep my turbo in the boost range the whole time.

If you're into autox - then lag is a concern.. you don't want it too laggy...

Common sense here...

For instance.. if you're going to go single, don't go cheap or halfass your setup. Do things correctly. Vacuum lines, ignition, reliability mods. I'm sure he can go further in depth.. but don't half *** your setup. Tuning, mods, etc etc.... make sure they're all done properly. You should be confident with your setup when you're doing it and/or done with it. If you're iffy about a component you're throwing in.. maybe you should reconsider your setup.

If the harness is all crispy and needs replacing.. replace it... you'll spend some money but your car will thank you for it!

tks for replies guys....

What about intercooler? i have the m2 medium but i was under the impression that most sinlge guys use a front mount. Which front mount is the best for a t-78?

One thing that struck me as odd when i was speaking to ray was that its gonna cost me $5100 for my motor even is my core is good. my engine runs great and makes 360 and traps 118 so i think the core is good. if he only needs to pull it out, port it, and reinstall why would the cost be the same as starting from scratch buying a reman etc?

It depends on the complete setup, and turbo size. Just like the poor man's non-seq setup is not as good as compared to a complete full non-seq setup.

You can have a single that has lag below 4000rpm but still make more power down low than stock seq twins, so it ends up being a meaningless point.

The A-Spec GT35R kit is one of the best all around driving kits you can buy.
Full boost by 3500rpm and very little lag unless you are in the wrong gear and do not know how to properly use them.

You need to drive a street single to truely seperate fact from fiction.

matty

i received a couple pm's from guys recommending the gt35r kit. any clue what kind of power it makes? Everyone telling me how fast the gt35r spools but doesnt mention power. I was underthe impression that in order to make 500 plus rwhp i am gonna need a laggy/decent sizzed turbo

If your looking for around 500whp and little lag I would strongly suggest looking at our 500R. It will allow quick spool on pumnp gas. And higher P/ratios on race gas. The 35R with the 1.0 T4 is a great performer we got 436whp at 14lbs if memory serves. Depending on a few things we see 1bar anywhere from 33-3500rpm. The transient response is really good also.

I converted mine over and broke 400rwhp with it 6 years ago. Still works just fine and will if you use the right gas for the application. The higher the effective octane, the better.

Just let Ray take care of you, your car will be fine, he has tons of experience to let you know what works best for your intentions and budget.

matty

yeah i feel good about him....one thing that struck me as odd was that my rebuilt would cost the same even if my core is good. I am sure that i am not understanding what he is saying. If my core is good it will cost me 5k to pull engine port and reinstall. if my core is bad it will still cost me 5k for the same work plus a reman. how could this be?


i am thinking about the 500R. does anyone have dyno results. bASICALLY I AM thinking about the t-78 and the 500r.

really appreciate all the help so far guys. i been around 7s for 15 yrs now....but havent spent much time looking at turbos until recetnly.

A3ON7

thanks for sharing with me the information. is really hard to know the difference between reading the information and to really drive it with the turbo installed.

A3ON7

well i have a thread about fmic and smic intercooler a couple of days ago and those vets was giving me advise to do a V mount intercooler. here's the link to the thread: https://www.rx7club.com/showthread.p...nt+intercooler

maybe u can learn something from there.

bmwjdmking

my buddy is running a t78. big results with his setup!

A3ON7

from what i'm reading it seems that T-78 turbo set up produce more result than 500R.

I have built and driven both. The T78 is a larger turbo and has higher "potential" but it has nowhere near the response. If your shooting for around 500 or so I think you will have way more fun around town being in boost sooner. 500whp and quick response in a light car like the FD is more than enough to scare the crap out of most and certainly more than enough for around town.

A3ON7

T-78 turbo spools at around 5000-6500 rpm right?

matty

4k if tuned right.

now the 500r....that will make 500rwhp at what boost? guys are making low to mid 500s@ 22psi on the t-78 and thats not even opening the turbo up yet.
I am interested in the 500r but dont see much results around for it yet. Also the t-78 is time proven winner!

A3ON7

wow....22 psi is kind of high don't you think, maybe zero R can scan the dyno chart on his car that he installed with 500R turbo.
