Computer issues
 

Ok so last night i raced a civic THREE times. Every time he got like a car almost two ahead of me.

My car has the following mods:
Full Racing Beat Stainless Exhaust (Header,Pre-Silencer,Y-Pipe,And Racing Beat Mufflers)

Turbo II Transmission

430 Differential

Rebuilt Bridge Ported Engine With 3MM Apex Seals

Judging by the Mods that should not happen against a ls vtec. i know that the only thing the civic has because is my brother in law's car.

Something i noticed is that when i get to 6000 rpm the engine gets stuck there, it only happens in high gears 3, 4 and 5. sometimes in 2 but rarely. And it doesnt go past 120 mph in 4th gear. so my conclusion to this problem is that the computer is bad or the msd box is going bad. i just need some opinions before deciding what to do or where to look. The MSD box i have doesnt have a chip. is a 6A.

Thanks in advance.

I'll go ahead and say it before the flood of people telling you to, check your grounds real good.

fixed.

Possible connection here, I think.

you have 110 untuned horsepower vs what? extra weight from the heavier turbo transmission/flywheel/clutch. who know's if your 6pi and or VDI is working?

n/a FCs are not fast nor race cars.

^^^exactly! Ls/vtec setups make about the same power as a ls with a t3/t4 on 6 psi according to sport compact car mag a handful years back. Just an ls swapped civic would probably walk you. He's got more power and most likely slightly less weight. Your bridgeport untuned is most likely causing your high rpm issues due to improper a/f ratios and timing maps let alone if your 6pi and vdi are working

Full or half bridge? 4 port engine? I hope you're not using the stock intake manifold and computer.

You don't have a computer problem.

I beg to differ...maybe not by todays standards, but, back in the day we were a force to be reconed with in SCCA Pro Racing "Escort Endurance Cup" class SSA. Were were third in points for the the season, 1986, behind 2 turbocharged cars, the Mitsubishi Starion ESI Turbo and 2nd place Dodge Charger with the 2.2 Turbo. We were the fastest naturally aspirated car in SSA and often beat some SS-GT cars...
but that was back in 1986.

I got this car about a month ago. The guy i got it from didnt even know what type of brigde he did. Yes it has stock computer and manifold

wasn't a similar question asked about this only a few days ago?

first issue is the stock untuned ECU is going to be a limiting factor, you need a tunable ECU to take advantage of a bridgeport if you don't know of how to tune around it.

next issue is it sounds like there is a fuel system issue, you probably have a bad connection at one of the secondary injectors or a faulty secondary injector. a heavy hesitation at about 6k is where you will see issues arise from only 3 injectors functioning on the stock n/a fuel setup.

I changed my mind. Im going with a turbo 2. I might put my rotors if the turbo 2 rotors are bad.

O.O

I HOPE by "bad" you mean the apex seal grooves are worn out of spec.

You can't run a bridgeport on the stock ECU.

You need more injector.

The stock intake manifold is a serious limitation to a bridgeport.

Just compare his timeslip to yours to find out where you need improvement. He'll always have better 60 foot times due to a wider powerband than an NA bridgeport. But really, all the stuff I mentioned above is the problem.

I'm just going to get rid of it and get something better

Get rid of the car?? o.O

Yes, and maybe save for a turbo 2 in good condition or maybe a fd. Im tired of non turbo engines
