Im not at all impressed with 379 to the wheels
at 15.5-17 PSI on his dyno sheets I think that is VERY sad Mod-to-HP ratio I made a bit over 400 at only 14PSI with a T66 .81 Hotside 11.72@118 Marshall should post what his car has run in the 1/4 and especially the MPH in that run that will indiciate how the car pulls with such a small A/R Hey you have your mind made up so go for it and we shall see who is right thats the only way to do it put real to potential too task |

I am sure surgemonster will jump in here soon. He also used a t66 with a very small exhaust side and did some pretty good things with it. If he doesn't jump in here you might want to shoot him a pm. he'll answer all your questions about it. BTW that turbo is ssautochrome's "GT45". he kind of names his turbos what ever he wants so if its confusing thats why.

Just giving him an idea that it doesn't choke the engine above 6k. |
not really pal
at the track the best MPH is 119.97 so you got me by .003 tenths :D |
Originally posted by kabooski not really pal at the track the best MPH is 119.97 so you got me by .003 tenths :D Hmmmm....you have more horseys and he still beat your trap speed. Do you think that could be because of spool time?? His turbo is in its powerband sooner, thus increasing his trap speed and lowering et's??? Perhaps a 4th gear pull on the hwy would show the advantages of a larger a/r turbine, but the advantages don't seem to show up on the street and strip. As far as daily driveability and the occasional auto x, It seems that using a smaller turbine will allow you to run a larger turbo without sacrificing driveability. Well done Marshall.;) |
Originally posted by fc1jz By the way, I know I am a cheap bastard, but so far I have this much of my dough into my setup (all items are brand new, and prices are shipped to me): ebay t70 Turbo+ Ebay divided manifold $500 HKS 40mm w/g $200 KGparts 2ndary Fuel Rail, adaptors for stock primary rail, braided fuel lines, aeromotive fpr and fp guage $450 1600cc injts $100 FMIC (no tubing) $400 Apexi Power FC+Commander (only thing not new) $900 Misc gaskets & flanges $50 .................... Not bashing but you need: Fuel pump down pipe/pipe for wastegate too I commend you on doing it on a budget however I myself would have went the extra mile to get a new garrett peice rather than buying the ebay t70.. but that's just me. |

And I was figuring the dump tube with the DP since I am having it exit through the exhaust rather than open air. I already have a gutted hi-flo cat/midpipe (for that emissions friendly look) and a catback. |
why has he not stated the 1/4 mile time?
theres no excuse (traction issues etc) I ran 12.3 on plain plain street tires with a 2.2 60" besides next time I hit the track im going for 10's : Also remember I have a FC FD trannies have slight diffrent gear ratios |
Originally posted by kabooski why has he not stated the 1/4 mile time? theres no excuse I ran 12.3 on plain plain street tires with a 2.2 60" nice 60", what type and size of street tires were you running? |
Toyo proxies
255/50/16 the 11 second pass was done on 255/50/16 BFG drag radials with a 1.63 60' |

Nobody slams 3540 owners. |
Originally posted by Marshall sorry, 12.20-12.40s @ 120, 2.1-ish 60's, street tires.

Nobody slams 3540 owners. Anyone remember the wheelspin factor during these runs??? Do you have anything done to prevent hop?? My car hops like a horny bunny when I get wheelspin. I need to get a diff brace. |
I'd give it a shot. You may be very surprised at how
well it works. I have gone down on the turbine a/r against conventional thought with very good results. |
I am almost done with the conversion now. Manifold fit good except The w/g flange holes were tapped crooked so I had to drill them out, and use nuts/washers to attach the w/g.
Turbo is hooked up with braided ss oil feed and return lines (fabbed at local machine shop). Next step is installing the fuel system. Power FC came in yesterday :D So I will be installing that as well. My intercooler is at the machine shop getting reworked for a custom setup to utilize the vents in my CF hood. I am hoping for a sort of venturi effect on the intercooler. I will keep everyone posted and I will take some pics soon. Whats left: Custom fab Downpipe and wastegate dump tube. Custom fab Intercooler tubing Couple more block off plates Install Fuel Rail/ss fuel line Install and tune Power FC And I am sure a few other things I am forgetting |
Did my fuel today. Need to know if i need to run resistors with 1600cc bosch injectors. And if I do, what specs on the resistor.
Heres what I wrote about putting in the fuel rail/injectors. https://www.rx7club.com//showthread....hreadid=299149 |
I was running 125mph with upgraded BNR stage 3 twins

Thats impossible Stephen! You're choking the motor with those stock exhaust housings.
:) |
just curious of any updates on this turbo man,...
|
me too

me 2

Thats impossible Stephen! You're choking the motor with those stock exhaust housings.< Yeh, impossible :-) I only did it 4 times with stock non-seq twins !!!! |
