50 trim in - lot's of smoke from exhaust - Page 5

**JET** · 05-10-2005

No need for DSMlink. There is a knock sensor in a 1g also, same threads. Just put your 2g sensor in there.

Yes the 2g head will go on a 6 bolt block. You just need to drill/ream out the head bolt holes since 6 bolts are 1mm bigger. There is a ton of press on doing the swap. I am sure vfaq.com has a full procedure for it.

Ok so you are saying since he's changing to a 1G block, a datalogger can then read the knock or?

Does the ECU get changed in this swap as well or?

This guy really needs to understand the concept of knock, how to read it and how to tune around it or he's just going to be right back in the same trouble again.

I used dsmlink for my 6 bolt in a 2g swap. I know when the battery has been disconnected and the settings in the link have been reset, my car misfires horribly without dsmlink.

I also reused my 2g head, thermostat, waterpipe, some of the timing componets, intake, throttle body, wiring harness, pulleys and accesories. Only thing 6bolt was the shortblock, lower timing cover, oil filter housing, waterpump and 1g cas.

Good choice on the 6 bolt. The people that are making good power on the 7 bolts have the knowledge and know how to swap crankwalked or bad 7 bolts with out too much time and effort. I know the guy who was making the most power on the 7 bolt used stock internals and collected various 7 bolts so that he had a fresh supply of parts when things went bad. He wasn't building up the bottom end at all.

ok, do i need dsm link or not? because i would like to know - i was told i don't need it, i really don't understand the concept of knock at all>> i'm sorry for being a newbie about that but all help would be nice on that subject!

DSMlink was needed in my case for getting rid of the Random Misfire issue that 2g owners tend to have when swapping a 1g CAS (needed for 6 bolt swap) into there setup to replace the signal of both the crank position sensor and the 2g CAS. Damn that was a long sentence...

A few people have had sucess without DSMLink by making very small adjustments to the 1g CAS once base timing has been set. RM sucks and is near impossible to get rid of unless you have DSMLink or use some other hack. DSMLink can ignore the random misfire checks by the 2g ECU, thats why people say you need it for the 6 bolt swap.

All the other good things DSMLink can do will help you from ruining your motor if you can have someone help you tune. Its nice to know when and how your engine is knocking, knocking under load will make quick work of even the best built engines. You can capture all of this with DSMlink, where as pocket loggers can not log knock on 2Gs.

I have a 6 bolt in my car (97GST) and I have put 2 - 6 bolts in 2 other 2nd gen DSMs and I havent had a problem with misfire in any of them. I thought I had misfire in my car but it was just a bad plug wire. I guess some just get away with it. I'm sure not everyone with a 6 bolt in a 2g has DSMlink. So either deal with the misfire if you get it or get dsmlink.

**Kracka** · 05-10-2005

YOU DO NOT NEED DSMLINK! Knock is not readable since you'll still be using the OBDII ECU. Make sure Shindley knows you are using a 1G 7-bolt head.

Raptor · 05-10-2005

We do a lot of 6 bolt swaps without issue or DSMlink. I wouldn't worry about it unless it ends up being a problem in your case. Cross that bridge if and when you get to it.

BKs50trimGST · 05-10-2005

he knows, him and mike from qpr talked about everything that needs to be done - the 7 bolt head he knows about. mike made sure that i get stock mains or else if we put in arp mains we align hone first - i heard about the incident with jet and shindley - cranked 6bolt because of the arp mains not aligned honed. will a 1g intake manifold give me noticeable power gains? also- probably stupid question - how do u get your turbo to spool faster - i know u can get a new exhaust manifold or port it out, but what's other ways of getting it to spool faster>?

BKs50trimGST · 05-10-2005

cuz right now even though i am really happy about the turbo, it spools around 4300rpms and i'm not used to not being able to spool fast, like the stock turbo did.

**JET** · 05-10-2005

One of the big parts with spool is having a free flowing exhaust. And PLEASE use some decent punctuation and capital letters! Your posts are a bitch to read sometimes. Your 50 trim should be spooling at ~3600 rpm on a 2.0. There must be something wrong or you have a really big exhaust side.

For the 30-thousanth fucking time: use a 1G throttlebody and 1G intake manifold with the 1G head to make this work together as easily/best/cheapest possible.

For once I wish Craig would go out of control!

BKs50trimGST · 05-10-2005

well, when i get the car back from shindley, hopefully soon - i will be able to check what my car is spooling at, i think it probably does spool around 3600rpms. i just never watched the boost gauge until i really felt something. what do u mean by big exhaust side? stupid question> and u mean free flowing exhaus meaning - something that won't hold it back, correct> like having aftermarket 3" all the way - which i do have, i have the Xtreme/Thermal 3" SS turboback set-up with the test pipe.

BKs50trimGST · 05-10-2005

kracka go easy, i know, i'm putting that in when i rebuild the 6-bolt. i'm just wondering if i will see noticeable power gains>that's it!

You would probably want dsmlink either way to log. It should run fine after the swap without it though.

BKs50trimGST · 05-10-2005

ARE U ALL HAPPY THAT I MADE THE DECISION ON THE 6 BOLT? i know it was the right decision - but damn, you all are a pain in the ass>> joking of course!

TheBlizzard · 05-11-2005

Great you finally found the fucking caps lock, now just try use the rest of your keyboard properly and we will not have problems. If people are having a hard time reading your posts and you will do nothing to correct them I will make sure you don't post on here anymore. Fix the problem or I will.

No shit, I wouldn't even think of using a 7 bolt if this happened to me....

btw, my 95 is currently at QPR getting a 6 bolt... and nobody had to even talk me into it!

If you're gonna do shit, do it right
