alright i just bought my 94 fd while i am in japan and my buddy bought my 91 gto(3000gt VR4) which is bone stock and my fd has a catback as its only performance mod soo far. well we raced a lil; from apox 50kph 2nd at 3800rpms-mid 4 th and it was pretty much dead even as he jumped out about a nose and on the 4 shift i started to pull ahead and had to let off due to traffic. does this sound about right? i know the gto is fast but i thought the rx7 was faster. anyways i ordered a down pipe and am looking for an intake. just wondering if my car is performing like it should. btw the car pulls insane from 4500-7500.

 

Good to hear the second turbo is working then.

 

That sounds about right, a friend with a 92 3000g VR4 and I where really close in straight line power when I had my fd with a few bolt ons.

 

yeah but i think it has a manual boost controller because the gauge shows 8 psi insatantly and doesnt drop until the 2nd one comes online and you can feel it but only for a split second and then its back up to 8 and it feels like the car is pulling harder after the second one comes online its just not at 10 psi.

 

your boost should read 10psi

 

10psi is stock... but it up to 10 then maybe just maybe you coul crawl away from him

 

i know it should but it doesnt get over 8 its always in the vaccum area at around 2-5 at idle or when driving normal not in boost. is this normal? but like i said it jumps to 5 at half throttle and instant 8 full then drops to 6 and back up to 8. idk if there is a manual boost controller or something limiting it, can anyone tell me where to look for one to check?

 

I'm new to FD's also ( I've had mine for a few months), but 10-8-10 is the correct stock boost pattern. 8-6-8 means something is wrong. At idle vacumn should be about -17mmHG, that what my boost gauge reads.

Boost leak maybe?

Hope this helps.

 

sorry psi not mmHG

 

i think the gauge isnt calibrated to be honest with you i can not find any leak at all. i may have a small exhaust leak but i will worry about that on sat when i put in a new downpipe.

 

see if you can borrow a firends gauge

 

The VR-4, if bone stock, should only be trapping ~100-105, so I would think with some very basic mods to the 7 it'd be no contest.

 

alright the boost issue is solved and i have added an intake and this weekend a down pipe but either way i could/would have beaten him but we had no room to really run japan is pretty crowded. but i know i will beat him now. and i know this because i used to own the gto sold it to him to buy my 7.
