turbo or no turbo - Page 2

Zeiss · #16 08-06-2005, 10:59 AM

Im not racing pro drivers by any means for one thing. And the races vary from 0-60 to 40-100 etc. even up to 150 mph thats when you start loosing them

haha. Im not racing at a strip or anything just a few jaunts here and there. The GTPs i have had "run-ins" with were not impressive, probably stock. 305 camaros are less impressive then the GTPs I have raced. Even worn 350s can get beat, not like ls1 material but you know the older style. Like I said though depending on the race, from a highway or stoplight it differs. I live in MN, you?

a stock vr4 can beat a stock tansam or ss-z28 camaro to tell you the truth... ive raced a 02 transam and beat it many times and the 2002 trans ams are the ones that came with the aluminum block and heads its the same ls1 they put in the z06s. ive beat a z28 camaro easy and a single cab SRT-10 with ease... this was back when i only had exhaust BOV and boost controller. the transam has full exuahst and headers. the z28 was the same as trans am. and the SRT-10 just had full exhaust. but now i woulndt be abel to test this theory because im far away from being stock now...

zeiss could have himself a factory ringer, but it just seems a little wierd that you're beating those gtps, but more power to ya.

92vr4red, hes non turbo.......

Zeiss · #20 08-06-2005, 06:27 PM

Ive seen the times for GTPs you guys listed but I dont know that just seems hard to believe from the few I have raced. I havent raced a full quartermile like from a stop just like I said so maybe its true

. Just highway races with them or smaller jaunts. And yes i have raced LS1 trans ams, they are beasts. Btw do you guys know what GTPs are governed at or top speed?

92VR4Red · #21 08-06-2005, 08:39 PM

oh didnt know that... then hes lieing no non-turbo could beat v8 camaros

Zeiss · #22 08-07-2005, 02:56 AM

uh yeah right i owned a 92 camaro 305 and it sucked balls, I hope your not serious. even the 3rd gen 350s are not that great. Maybe you should clarify V8

please remember im not racing proffesionals on a closed course. Little jaunts where I can choose my gear

Why do people think na are so slow? And "no non turbo can beat a v8 camaro" please

Used tubors are really cheap. you can go to DSMtrader.com and find some 13bs or 14b for like a $100 bucks a peice... but seince your a SL this is what will be involved to comvert it to turbo.
First off your compression needs to be lowered... that is something you cant really do your self... so you would have to have it built to 8:1 compression. then once you have that done you will have to then but new exauhst manifolds that will allow the turbos to bolt up. new downpipe, intercooler/s, and new intake lines, and then once you have that done you will have to get it tuned with a piggy back MAPing system (MAP-ECU) because it will have to be running just right not to destory the engine. all in all i mean thats about a $7000 - $10,000 conversion (the right way) and if you where geting new turbos then it would be alot more ALOT. and thats just to get it running... to get it running like a vr4 you would have to get alot of stuff... the SL throttle body is much smaller than a vr4s and the intakes is smaller too... i mean once you get into it... it is a very pricey thing to do... i can go on forever. you would be better off going and buying a vr4 or a JDM vr4 engine and drop it in.

Lets see here. There are multiple, many, many, many 10:1 conversions running around on 8psi plus. 8psi on There are several running above 10 psi as well. The turbos you mentioned will not bolt up to stock VR4 manifolds. You would either have to get TD-05 adapter plates or TD-05 headers. You can use the stock TT wiring harness and ECU with the addition of an SAFC and the car will be fine. The DOHC TB's are ALL 60mm. NA and TT have the exact same size ones, only difference that I know of is the TT one has a dashpot. Jeremy C over on 3si did the 10:1 conversion for just under $2000 if I recall right and his car has been running fine for the last 2 years.

GTP's arent all that great. I ran a 97(?) at the track and the best it could pull was 15.5. If they add a pulley and chip it then its of course going to be faster.

13b's are bolt up, 13b's off DSM are very close to bolt up.

i did say you had to get new exhaust manifolds didnt i? never said they would just bolt up.

Jomojr · #28 08-07-2005, 11:41 AM

Just as an FYI my tt conversion is running great as a 10:1, I run 10psi daily, and can turn it up to 12 if I feel like goin to the track.

92VR4Red · #29 08-07-2005, 11:45 AM

thats just my point though... i said you wont be able to run more than 10 psi... i can run well over 20 on my car when it was stock and had no problem with it. if you cranked it up to 20 you will mess things up.

might not be able to run 20 on pump gas, but from as much as i have run on pump gas before, i should be able to run that on race gas. And even if not, it still doesnt matter, IPO ran mid 11's at 10-12 PSI on his single big turbo back when he was 10:1 and it was just SL-T
