Alright Friday night I met up with my buddy that has a 94 se-r with a turbo kit on it, I think t25 and cams. He let me drive it on our state street where everyone cruises for races and we simply whoope on anyone that tried to compete ex... brand new civic si with plenty of addons, eclipse, and it was wet out. Anyways he is running with stock boost, stock as in de ecu, and it isnt quite tuned all the way yet but the car pulls so damn hard its amazing. I felt like god when I was behind the steering wheel. His buddy that just came over from N.C. has a se-r with the det swap and his is slower than the 94 se-r, and the NC dude is boosting like shit I cant remember, 7-8lbs. and has a 2 1/4 exhaust, but it doesnt seem to be as fast. Is there a reason for all of this, I have always read that the swap would give you more power than adding onto just a de. Any reasons anyone can think of?
Peace.

det boosts 7 lbs. stock and they do not like that small of an exhaust, he should def. go get a 3" exhaust. is the guy with the t25 running anything else with the turbo, ex. FMIC, cams, etc. and did the guy with the det get a jwt ecu? if not, he could be having some air/fuel probs. that need to be worked out.

Well yea the guy with the t25 has a fmic, cams, and a 3" stromung exhaust but is boosting 14lbs lol. The guy from NC does have a jwt ecu and also a fmic but is still boosting 7-8lbs. Its weird lol.

Well your post didn't make that much sense, but let me guess what your trying to say. You drove a se-r with a t25 and cams at 14PSI with stock ecu. And your other friend from NC has a sr20det swap and is on stock boost with JWT ecu.

The reason the car you drove is so much faster is because all the exhaust gases are flowing more freely. The cams deffently create the exhaust gases to flow better and the 3in exhaust gets the gases out faster. Plus you have 6 more pounds of boost the the SR20DET swap has. Plus the cams make a signifigcant power increase.

Now for the other car. That car is at stock boost which is fine, but he needs to get a 3in exhaust piping all the way. He will notice a increase in power due to the exhaust gases flowing more freely.

Now for the swap giving more power then a DE+T I don't know. That's mostly opinion. Right out of the box I think that a swap would give you more power, bu tif were talking big power 350- 400Hp then you can turbo a de and get just as much power as a Sr20det. This question is all personal opinion

ahah thnx man, sorry about the confusing posts, im kinda still fucked up from last night :(. So what you are saying is if the guy with the det would get a 3" exhaust he will notice a huge diff? Or would he need to get cams too?

Well the 3in exhaust will help him out alot and he'll notice a difference but he would need to get cams to start feeling like the se-r you drove. So just tell him to get 3in exhaust then tell us what he thinks

Buddy #2 needs a boost controller, and can crank it up much more safely because he has a DET instead of a turbo-ed DE. JWT S3 cams, with sprockets (to dial out overlap) are said to be worth 30 WHP on an otherwise-stock (7PSI, stock fuel system, stock MAF, etc) SR20DET. I would say that between that and the small exhaust system, the DET is currently slower. Fix those three things, and the DET will be showing taillights to the DE(T).

A real DET can go to higher HP levels (300+) more safely than a DE can, but that's not to say a DE is weak. For about the cost of a DET swap, one could have an F-Max Stage-II turbo kit, and not be making much different power levels (230-ish). Start spending more money, though, and a DET starts looking like a better place from which to start.

thnx
