Help with stroker kit 8v

[CJAnsell]

Ok so I'm just about to bring my saxo off road for I'm guessing a good few months. I've just picked up a turbo so the turbo setup will be done. I'm sure once that's done though ill be wanting more power and as this car is just a project of throwing money at I've tried to find a stroker kit for a VTR. Of course this means it's an 8v and it seems even though I've searched far and wide (maybe not enough) I cannot find a kit for 8v's.

Yes I know the kits cost a bomb but I know what I'm getting into with pricing. The question is, does anyone know where to find the stroker kits for a VTR ?

[josh89vtr]

There was one on gumtree a few weeks ago. Think it was in Newport??

[CJAnsell]

Just checked, not there now. It seems the only kits I can find are for 16v

A decent forged boost set up should make ample power with out stroking out the engine!

[blackie_2k5]

16v kit will fit the 8v

It's really not worth it, if you were going to you may aswel do 16v engine


What's your goal? Other then to blow a small fortune by the looks of it

[CJAnsell]

I think a VTS engine is the better option I think.

I'm not trying to rebuild everything to then crash the car because of stupid ideas, it's more of just being a major project. I can afford the parts to do so but that pretty much it. It's just a project.

Have no decided about after that but could well use the car for track afterwards.

[blackie_2k5]

But what are your goals

You an run more power then you could use with a turbo set up, so no need for a stroker really

If wanting a big power n/a that nobody's really done.. Then yeah I could see a stroked bodied vts being worth it, but not unless

[adzvtr]

A stroker kit is a great idea even with boost.. will make for a much better allround drive. Theres no substitute for cubic capacity..

[VTRelite]

There's no replacement for displacement

With the cost of a stroker kit I'd fit an EW lump and get another 200cc.

I often wonder with things like this why people use odd base cars as projects.

If your just wanting some fun whiz bang for a few grand why dont you buy a GTST skyline or 200sx for very little and use that as the project base. I love saxo's but doubt i would consider spending a couple grand on a VTR for a laugh, knowing built, its worth about a tenner afterwards.

Im sure you could find some pistons that would fit the saxo rods.
For example, in ford land, 2.0 pinto pistons will fit the rods on a 2.9 cologne v6, bore the block out to fit and you go from 2819cc 7.5/1 to 3090cc (cant remember CC exactly) and 9/1. people throw out stock pinto pistons, great upgrade.

If you were to find a piston that would be a direct swap, allowing a VTR to be bored out to 1.8 or so, im sure people would be very interested.

[blackie_2k5]

You cant bore Saxos out matt, the cylinder walls are very thin as is, can only take fractions off for slightly oversize pistons on worn blocks

Even then it's not advisable if going boosted

[m4tt274]

aha, i never knew that! Ok well, scrap that idea.

[blackie_2k5]

There will be other pistons s that can be used, will be little known Info found by old fellas that have worked on cars for years and fucked about with them lol

The Saxo stroker kits work by increasing the stroke with "shorter" rods/pistons rather then over sizing the pistons and increasing the cc's that way

[m4tt274]

Yeah i guessed as much.
truthfully i have never had the head off a TU, some are surprised when i say ive never needed to, ive never actually had one break lol.

If you can remember the old xflows that were in the mk1 fiestas and escorts etc the 1.3 pistons will fit the 1.6 blocks, the 1.6 was just a longer stroke. :L

[atspeedracing]

the 1800cc stroker kits use a 80mm piston (+1.5mm) and of course long stroke crank.
bottom of the block needs machining for clearance of the rod on bottom of the bore walls.

buy a 16v kit. sell the pitons. buy 8v pistons, or better still get some made specific to your application.

never been a lover of 80m bore on saxo --too thin inbetween the bores --stroke it yes but leave it std or max go to 79mm --that gves1768cc from memory --still a big lift on 1587cc
latest ep engine has gone smaller bore and even longer stroke to get 1598cc --but they have been desinged with boost in mind ,so need the extra spacer between liners ,as they are now an alloy block with fixed in liners and a clear space between liners for water flow

I would also imagine that the EP has a longer stroke/smaller bore because of the fuel economy benefit that comes with downspeeding the engine.

[axsaxoman]

certainly cars are higher geared now ,so a wider spread of torque at lower rpm will suit that better,but i beleive the main reason is to get over the block problems of the tu5 --which has same bore spacing as its original 1.0 tu alloy engine which it was developed from and now at 1587cc the bore has gone from 69 to 78.5 --so it has come to an end of development and with running higher combustion temps block has shown its limit ,which is why the pistons are 6thou oval on the cast iron block engines to allow for block movment under high temps --new ep has round pistons as do all the alloy loose liner tu engines
