6 bolt vs. 7 bolt [merged] 6bolt 7bolt 6-bolt 7-bolt six bolt seven bolt - Page 8

Hey guys, I was just wondering since I already have my motor apart should I buy a 6 bolt shortblock to eliminate (or extremely lower) my chances of getting crankwalk.
Does the head from a 97 just bolt right up to it?
What about transmition?
What modifications are necessary to successfully complete this conversion?

dsmpride · 04-24-2005, 05:40 AM

The transmission will bolt right up. The head will bolt right up too but the bolt holes need to be bored out slightly. Other modifications include the wiring of the 1g cas. (Find more here)

Other than that, you should be good. And don't forget that if you have any questions, ask them. Its better to ask a question and do it right than to do something wrong and look stupid. Good luck on the swap!

i have a 92 turbo laser. how do i tell if i have a 6 bolt or a 7 bolt motor? I need a new head and want to know what i have. I found on thats ported and polished but dont know if its a 6 or 7 or even what mine is. Im new to this and would like to get my car running asap. Thanks for the help in advance. Cody

Well if you have a 92, the 1g 6 and 7 bolts both use the same head. In 95 they started changing to the smaller port heads. But you can tell by the corner manifold nut, headstuds 6 bolt are 12mm, 7 bolts are 11mm. Your oil pan, and flywheel bolts.

This may be a dumb question to some but it has been bothering me for some time. I am planning a 6 bolt swap into my 95' gsx this summer but I am curious as to what parts you then buy for your car. Obviously you buy 6bolt internal like rods etc.. but what do you buy for ic piping etc. How compatible are parts like injectors, heads, etc.. I'm sure I could search this forum for days and get all my answears but this way someone else has something to do like explain this to me when they are bored. I'm just curious how 7bolt to 6bolts parts are compatible. And if there is a thread about this that has been going on for some time just post the link. I will sleep better at night once this question no longer bothers me. lol

How to do a 6 bolt swap and what you need
http://www.magnusmotorsports.com/article_1g2g.htm

I'm pretty sure you can keep your stock piping but if you go for a 14b/16g, you will need the j-pipe and a few other parts. Also, you may want to get a 1g throttle body and intake manifold too along with the head.

t3/t4eclipse · 05-04-2005, 10:05 AM

Hey thanks I appreciate it. However I am still curious as to what aftermarket parts to buy. Do I buy parts for a 2g or a 1g like intake, ic piping, etc... Do I buy the parts based on the motor im using or on the shape of the engine bay and body. I might be wording my thoughts wrong. sorry.

dave99gst · 05-04-2005, 10:13 AM

everything you listed would be 2g parts.
they have nothing to do with the motor.

Attack Eagle · 05-04-2005, 01:06 PM

and if it 's a 99% street driven daily commuter car you may consider using the 2g head and doing the so called "block only" swap.

I just got done with mine last week and the car looks bone stock... everyone is disappointed when they pop the hood and there is nothing to see except that it is clean.

you will need everything 1g from the pan to the head, and from the rear seal plate to the plastic covers, drill out the 2g head to fit ARP studs... and reuse your 2g thermostat housing and water piping and water/oil cooler on a 1g stand. IF you want the straight bolton way then you can use a 1g thermostat housing, neck, and water pipe. I had the 1g thermostat housing and neck brand new but chose not to use them
you also need a black top cas.

Best of luck to you! If you have any questions PM me.

I just bought a 1g 6bolt bottom end with everything in it now i need to know what do i need to buy and what needs to be taken out of my 2g. Besides the new cltuch, and oilpan what else needs to be changed for me to do this convertion. Also what about my crank sensor is it the same? please can someone help me on this steps on how to do it??? thanks.

ADrewzki · 05-07-2005, 05:06 PM

You should really do a search on this. There's about a million threads on it. There's one by hellotbone which I like because it has a lot of pictures and it's pretty well written. Search button.

blackGSX2g · 05-07-2005, 07:36 PM

Search on the RRE site and the Magnus site for more the broad checklist and come back when you have more specific questions. I will be glad to help you then.

I just completed the swap... look at my posts...

HazardTSi · 05-11-2005, 03:51 PM

I have a 91 Talon TSi that I wrecked. Pretty much everything major is bad except the Engine. My question is this: Would it be possible to swap a 1997 Eclipse GST Motor for mine? If so, what kind of $ am I looking at? Thanks.

marcmsj · 05-11-2005, 04:14 PM

yes you can... people do it all the time... price you're gonna get for it depends a lot on the condition of the engine (compression, etc.) and the mileage.

HazardTSi · 05-11-2005, 05:05 PM

Well the cars motor went after about 20k, then was rebuilt. Currently has about 85k. It's in good condition. I've ran it hard and only had one problem with it... I have to put tape on top of the ECI part. If I don't, it sucks in air and makes the motor stall out and die.

HazardTSi · 05-11-2005, 10:40 PM

Guess I should better phrase that... I have a 90 model Talon TSi (not 91, sorry). I am wanting to buy a 97 GS-T with a blown motor. How much price and effort would it be to trade my current 90 engine with the 97. both 4G63T right?

It's not too difficult. Start here http://www.magnusmotorsports.com/article_1g2g.htm and then go here http://www.roadraceengineering.com/1gcasin2g.htm

They go over a few, 6 bolt bottom end / 7 bolt head issues in this post... Will a 2g head be good enough?
I have a 6 bolt bottom end, being machined in the shop right now for this setup.
